The following are the session descriptions for the
2019 EEBA High Performance Home Summit:
High performance builders, such as those who typically attend the EEBA Summit, have responded to the challenge to continually improve the energy efficiency of homes as they progress along the path towards Zero Energy Ready Homes. Simultaneously, consumers, in response to increasing land values, and access to more information are becoming more educated about the place they call home. They have new expectations for their total living environment that ensures safer, healthier, more durable and more comfortable homes. Builders will find in this session that they can leverage familiar building science principles and strategic partnerships to deliver the next generation of homes that are healthier both for their homebuyers and their communities. This session will empower participants to take the next steps beyond just energy efficiency and onto overall homeowner and community wellness.

Where can you find new employees and how will you keep them? What are the priorities of the new generation(s) of workers? This session will look at strategies for recruiting and investing in young employees with the goal of making long-term career out of skilled trades.
Americans want what high performance builders are selling! But there’s a pretty big gap between desire and action. Fear of the new and unknown, confusion about terminology, and misinformation from conventional builders all get in the way of fully leveraging your value proposition and closing more sales. Suzanne Shelton, CEO of Shelton Group, will share her firm’s latest consumer insights and give participants a how-to guide for messaging and marketing to move Americans from desire to action on high performing homes.
Understand who wants smart, healthy, efficient homes and why they want them
Learn the messaging that’s most effective to pique their interest (and what messaging doesn’t work)
Learn the visible cues that need to be present in your homes to give you an advantage
Get specific marketing steps and techniques — and even tools from a recently released toolkit — to drive customers to your homes.
Considering that ASHRAE 62.2 is titled Ventilation and Acceptable Indoor Air Quality (IAQ) in Low-Rise Residential Buildings, then dilution must be the solution to indoor air pollution, right? FALSE! Efficiency programs have historically focused on rates of dilution, even though it is only one component of IAQ. In many areas, the outside air contains higher levels of small particulates than the air inside a house. Does introducing this air unfiltered make the IAQ better or worse? Recent research has shown the potential negative health implications of ultra-fine particulates and the importance of fresh air distribution. This session will focus on strategies to incorporate the four horsemen of IAQ: filtration, dilution, source control, and distribution. Participants will learn how to establish and maintain high levels of IAQ and not just check a box to determine air quality.
The entire utility industry is migrating to time-of-use rates and demand management programs. That means your customers need homes that are built to respond, dialing down energy use during peak demand and automatically turning on key functions, like water heating, heating and cooling or dish washing, when the price is right. Hear from Rheem and two of their utility partners as they share how they’re creating products and programs that are “utility ready” so you can build homes that are as well. Learning Objectives:
The U.S. Department of Energy (DOE) Building America Program has been a source of innovations in residential building energy performance, durability, quality, affordability, and comfort for 20 years. This world-class research program partners with industry to bring cutting-edge innovations and resources to market. In 2015, Building America developed a 5-year Building America Research-to-Market Plan that contains a set of three integrated Technology-to-Market Roadmaps. In 2019, Building America awarded 11 new research projects to complete the 37 project portfolio. This session will discuss how this research portfolio and complimenting industry activities combine to accomplish the objective of the Research-to-Market Plan; advance technology adoption, promote high-performance buildings practices, and ultimately save energy. Building America research has evolved over the years to address the most pressing building science and systems integration questions facing the U.S. housing industry. This session will build on previous building science advances and identify a new set of challenges facing the housing industry today, including growing housing industry needs for “smart home” technology integration and advanced construction technology to improve construction productivity and housing affordability. Smart home technology integration will address emerging research questions associated with grid-modernization and connected devices. Advanced construction technology research will explore the application of modern manufacturing methods such as modular and panelized systems, and the integration of those systems into new construction and retrofit solutions. The addition of these important research areas provides new and exciting opportunities to significantly improve the energy performance of American housing.
Do you know the Institute of Business and Home Safety has a Fortified Build program to ensure a home or business is more disaster-safe? FORTIFIED Home™ is a set of engineering and building standards designed to help strengthen new and existing homes through system-specific building upgrades to minimum building code requirements that will reduce damage from specific natural hazards. The FORTIFIED Home program has three levels of designation—Bronze, Silver and Gold—that build upon each other, allowing you to choose the desired level of protection that best suits your budgets and resilience goals.Why we did it at our Habitat for Humanity affiliate? How we did it? What were the costs? What strategies we carried forward after constructing the first Certified Fortified Gold home in Minnesota.
Many AC’s and heat pumps are installed with faults that impact both their performance and efficiency. Come to this session to learn about a new RESNET/ACCA/ANSI standard with three simple field tests that can help a builder ensure they’re getting what they’ve paid for. Not only can this make for happier homeowners, fewer service calls, and lower utility bills, it can also unlock new points for homes with a HERS/ERI rating.
he U.S. building industry is beginning to use advanced manufacturing techniques, off-site prefabrication, and modular construction approaches to overcome barriers of labor expertise, cost, and speed of construction of buildings. However, the industry has not yet leveraged the benefits of off-site factory built construction to achieve higher levels of cost effective energy efficiency, advanced controls, and distributed energy generation strategies. In 2019, NREL has engaged the leading multifamily volumetric modular offsite construction factories to understand how advanced manufacturing provides a transformational pathway to cost-effective, energy efficient, affordable housing. We will discuss specific factory construction approaches to include barriers to system integration such as 1) problematic on-site installation, commissioning, and configuration of building controls, 2) poor installation quality of thermal and air barriers, 3) a lack of integrated and modular HVAC and Domestic Hot Water systems, and 4) lack of cost-effective integration for new grid-friendly design and emerging technologies. Our effort underway seeks to answer the question: “How can we achieve optimal integration of energy efficiency strategies and control systems through advanced manufacturing techniques and technologies with little or no additional cost?”
Zero energy ready homes and communities are emerging across the United States as the evolving building energy code sets higher requirements on energy efficiency and more home buyers are becoming conscious of the benefits of zero energy ready homes. With the installation of onsite renewable energy systems such as rooftop PV, a zero-energy home can offset all or most of its annual energy consumption. However, integrating residential communities with high-penetration PV may bring many challenges to the grid. Existing solutions, such as PV curtailment, battery storage, and direct load control, are not able to fully leverage the energy efficiency features in the zero-energy design of the homes or address the grid challenges in a cost-effective and holistic way. The National Renewable Energy Laboratory (NREL) is collaborating with Thrive Home Builders to develop and demonstrate a community-scale control system to overcome these challenges. The solution leverages the energy efficiency features of the zero-energy ready homes and advanced controls of the behind-the-meter assets to address the issues brought by high-penetration PV. This presentation consists of two parts. First, Thrive Home Builders will introduce the Waterfield Community, a zero-energy ready community in Fort Collins, Colorado, and the innovations from the design and construction perspective. Next, NREL will present novel methods on optimization and intelligent operations of the community, including 1) optimal rooftop PV placement based on the community’s renewable energy goals, 2) physics-based gray-box modeling of various residential building types for large-scale simulation study, 3) machine-learning-based end-use energy consumption estimation, and 4) a hierarchical control system that integrates these innovations and provides benefits to homeowners and the distribution grid. The homeowners will benefit from reduced utility bills and carbon footprint, and the distribution grid will have enhanced reliability and resiliency, which will, in turn, benefit the homeowners as well. We will present results from simulation-based study and recommendations for the design and operation of future zero energy homes and communities. The presentation will conclude with generalized guidelines for various stakeholders such as home builders, homeowners, utilities, technology vendors, and researchers.
EEBA Site Supervisor Certification is a one day course that covers how the knowledge, processes, and best practices gained from building science apply to site supervisors for residential construction projects. Similar job titles for a site supervisor include project manager, construction site manager, foreman, and field superintendent. All participants will be encouraged to raise questions, share their perspectives, and offer examples from their job sites. We will focus on actual job-site and real-world applications and the resulting value added to the company, the job site, and the consumer. Broad topics will include the following: Building science fundamentals Whole building integration, Building testing, and Quality Management. Applying experience from the job-site to integrated design Attendance and completing and passing a quiz at the end of the course will result in EEBA certification. This course is consistent with guidelines developed by the U.S. Department of Energy for building science education.
Cladding Systems, Moisture Protection, Thermal Control and Air Barriers: Effective Enclosure Strategies. This interactive workshop will examine the unique considerations of building enclosure design for wood, masonry and steel framed projects. Presented by two experts, it will break enclosure design into its main control layer topics: cladding systems, moisture protection, thermal control and air barriers. Each of these control layers will be addressed, including product options, assembly and detailing strategies, continuity, inspections, and how each control layer affects the others. The presenters will demonstrate best practices in high performance buildings while addressing lessons learned and construction sequencing challenges. While discussing materials, durability and composition, specifically chemicals of concern, will be assessed. Attendees can expect to gain a deeper understanding of the guiding principles of enclosure design, the variety of products, assemblies and details that can achieve desired performance, and the construction phase know-how to ensure that pen and paper details translate to real-world results.
Electricification of homes and cars will be the path forward to mitigate climate change and meet city, state and the Paris Climate Accord goals. The nexus of homes with solar, EV and battery technology and the grid make the increases the planning and strategy for the developer, builder and the utilities. How do all these new technologies work together to create more cost effective and sustainable homes not only today but for future generations. A esteem panel of researchers, policy makers and builders will discuss the path forward and what builders today can do to prepare.
This session will explore how emerging technologies in indoor air quality (IAQ) monitoring and smart whole-house ventilation systems could reach maximum potential in hot and mixed-humid climate zones and lessen industry push-back on fresh-air and tight building requirements. Presenters will dive into actual research findings from field studies utilizing real-time IAQ monitoring. Findings will include preliminary results from a current Building America project titled “Performance-Based IAQ and Optimized Ventilation”, which explores how a smart, weather-optimized ERV performs in the hot, humid south compared to a typical, continuously operating ERV. Additionally, presenters will demonstrate ASHRAE 62.2-2016 Relative Exposure calculations and how these calculations compare to real-world data.

Understand the implications of different climate zones and building assemblies on the Energy Rating Index and HERS scores. Attain a working understanding of computer modeling and the major approved energy rating software packages used in calculating an energy rating.
High Performance Mechanical Systems for Houses That Work is a mid-level, full day seminar geared towards Builders, Designers, Code Officials, and Trade Allies that focuses on HVAC, Ventilation, Hot Water, Indoor Air Quality and Electronic Home Controls in high performance housing. In the past several years, residential mechanical systems have grown in complexity and scope as energy codes have mandated higher insulation levels, better windows and tighter construction. There is now a great opportunity to rethink and redesign HVAC, hot water heating and electronic home control systems as they are major contributors to energy efficiency goals. This course will first review the key building science concepts that have changed the way houses are built and identify the relevant changes to mechanical systems. The remainder of the course will focus on the proper sizing and selection of appropriate mechanical equipment for high performance ever lower load homes. Compelling opportunities to simultaneously optimize comfort, durability, safety and health, efficiency and cost will be identified. Instructor will use lectures, case studies and group exercises to convey the information to attendees.
Based on years of field research from the US Department of Energy's Building America Program, our Houses That Work™ program provides proven techniques for boosting a home’s energy performance and your profitability. The climate-specific content includes measurement tools, the latest design concepts, application demonstrations and case studies.
As we build tighter homes to meet net zero energy requirements it is essential that they are also durable, safe and comfortable. This session will identify the most important IAQ challenges in new, energy efficient homes based on lessons learned from recent field studies, including an LBNL study of ventilation and IAQ in 72 mechanically ventilated. We will discuss source control, effective kitchen ventilation, efficient air cleaning and filtration, humidity control, and occupant education. We will show how the potential application of smart ventilation systems can save energy and help with utility-scale demand response while also improving IAQ. This will include the latest information on IAQ sensors & monitors: what they can do right now (and what they can’t) and what is coming in the future.
A key to ensuring the quality of HERS Ratings is to enhance the consistency which the various accredited HERS software programs calculate HERS Index Scores. Too often in the past, the same home could receive a different score based upon the software program being used. For the past four years, the RESNET Board has strived to enhance the consistency of the calculation of HERS Index Scores. A big step has been achieved with the formation of the RESNET Software Consistency Committee. The Committee is formed as part of a mechanism by which RESNET can improve the consistency of HERS Index Scores and modeled energy consumption (based on the RESNET/ICC/ANSI Standard 301) among RESNET, accredited HERS Rating Software Tools, and enhance accreditation testing parameters. This is intended to be a continuous, ongoing process aimed at improving consistency. To guide the efforts of the committee, RESNET hired an Energy Modeling Director. The RESNET Energy Modeling Director will act as the arbitrator of the Software Consistency Committee, making technical decisions about modeling tests, requirements, and guidelines with the support of other members of the committee. The position will also be the liaison between the SCC and RESNET staff. In this session, the RESNET Energy Modeling Director will describe the efforts underway to improve consistency among HERS Rating Software Tools.
Since 2017, Building America has been conducting an indoor air quality field study in multiple regions of the US. This as been a collaborative effort among the US Department of Energy, Lawrence Berkeley National Lab, Pacific Northwest National Lab, University of Central Florida's FSEC, and University of Illinois' Indoor Climate Research. Profiles of various contaminants of concern are being measured, and occupant activities impacting pollutant emissions are being tracked in homes with and without whole house mechanical ventilation. In this session, the data collection protocol will be presented, along with preliminary results characterizing IAQ in new homes, and identifying associations of indoor contaminant levels with the presence of whole house mechanical ventilation.
This award winning builder has successfully been building high performing homes for the last 34 years. He is constantly fine tuning his business plan. For the past 15 years he has mantained a waiting list of new customers who are willing to stand in line for a construction opening. Has built off grid and has lost count of the number of ZEH and near ZEH he has built. Spend an hour to learn how he makes it work.
As a product manufacturer with a long history of selling healthy air solutions, Aprilaire has been helping the HVAC trade increase IAQ product sales by educating consumers on the benefits of a healthy home for more than 60 years. They are uniquely aware of how quality indoor air is the grabbing the top spot on homebuyer’s checklists and how to deliver it. They’ve also worked directly with home builders and raters to understand the biggest IAQ challenges new homes face. 15 Light Years is “Energy & Electrical Experts on a Mission:” they provide builders and owners clean energy solutions, as well as test, verify, and certify new construction projects with the goal of higher performance and greater energy savings. They are driven by community and a greater purpose. Every time a customer invests in their service, they directly fund STEM learning programs for youth and adults in their community. Aprilaire’s Scott Grefsheim and Tim Smith of 15 Light Years will share with home builders how IAQ products work to meet code, improve building performance and ultimately help to deliver a strong promise of health to the homebuyer. Aprilaire’s Joseph Hillenmeyer will speak to how builders are successfully marketing IAQ products to raise the value of their homes, differentiate from the competition and meet a growing home buyer demand for healthier homes.
Tightly air-sealed, well-insulated buildings combined with increased ventilation rates has become mainstream, and in many cases required by code, and there is no going back. Better construction requires less heating and cooling, and better moisture management. In many cases, traditional HVAC equipment will not provide adequate space conditioning in high performance buildings, leading to poor heating, cooling, and humidity control. These problems lead to uncomfortable homes, excess energy use, and, in some cases, legal liability for the builder. It is critical for builders to understand how the way they build affects HVAC design requirements, and how to properly choose “right-sized” equipment for their projects. Real-world data and case studies will be presented to show that when it comes to occupant comfort and health, HVAC design can no longer be an afterthought. Strong graphic images (and props?) will be used to visually demonstrate building science principals and show how the old ways of addressing heating, cooling, and moisture management are no longer viable. We will demonstrate how high performance building changes the dynamics of heat and moisture movement in and out of buildings, and the affect on HVAC design and equipment selection. This seminar will include three unique perspectives on the subject. One long time builder and building science expert will share his recent experience with ductless HVAC, ventilation, and dehumidification in a new high performance home. A second builder and equipement manufacturer with extensive experience in affordable housing will review designing and selecting HVAC equipment for high performance buildings. Finally, we will hear from a manufacturer that pioneered whole house dedicated moisture control solution about current available solutions and products in the pipeline to improve heating, cooling, ventilation, and humidity control in high performance homes.
Facing an ever-increasing labor shortage for both skilled labor and supervision, the residential construction industry is struggling to fill positions as the housing sector has recovered from the great recession. Come hear about efforts from EEBA, RESNet, and the Department of Energy to prepare and connect students to the high-performance construction industry and learn more about how to attract young professionals to your organization. Be prepared to be engaged in questions about the hiring of Generation Z/Millennials and how these groups have affected your organization.
The U.S. Department of Energy's Building America Program will present the latest developments in two of its premier tools for builders, the Building America Solution Center and the Building Science Advisor. Builders can work directly with both tools to improve designs, find best practices, train their installers, and work out code solutions. Builders and designers can use the Building Science Advisor to test out the moisture durability of their wall designs. This much anticipated tool is now ready for prime time. Find out where to find it and learn from the experts who developed it how it will work for your projects. The Solution Center provides research-based best practices and critical information to help give builders a competitive edge. Use it to find details for construction documents, images to help with training and presentations, code briefs to aid in communicating with code officials, and access to Building America’s library of research reports and other references. Business teams and sales professionals will learn how to create custom sales flyers, use terms valued by consumers, and develop materials to train sales staff. With these free tools any builder can improve their buildings durability and performance. This session will emphasize the latest upgrades and plans for these tools.
Radon is the 2nd leading cause of lung cancer in the U.S. (2nd only to smoking). So radon-resistant new construction (RRNC) is critically important, particularly for well-sealed, high-performance buildings. However, as mechanical whole-dwelling ventilation becomes more prevalent in new construction, misinformation and skepticism still exist about the value of radon mitigation measures and testing. And even the most well-intentioned builders can often miss key construction details that impact the effectiveness of a radon reduction system. During this session, you’ll hear from leading experts who will “bust” some of the common myths about radon, explore the science behind radon intrusion within a home, and address typical mistakes in the installation of both passive and active radon systems. Presenters will also highlight RRNC details that can be used to address issues such as expansive soils and unique foundations designs, which are common in many central and southern states in the U.S. Speakers will also provide updates on recent events in the development of national radon standards such as ANSI/AARST CCAH, while exploring how EPA’s Indoor airPLUS Construction Specifications can provide a valuable tool for builders to pursue RRNC and market healthier homes to their buyers.
Gain and Understanding of the science behind radon intrusion and movement within a home. Learn about best practices for designing and installing passive or active radon systems, including unique design considerations. Hear how national standards continute to evolve to improve best practic and increase the adoption of RRNC. Learn how RRNC techniques can help you earn EPA's Indoor airPLUS label for new high-performance homes.
High-performance, energy-efficient homes feature carefully designed strategies to maintain the integrity and functionality of the building envelope. These measures include continuous control layers to block or retard the movement of vapor, water, air, and heat. This presentation explores how these strategies compare and align with features designed to help a building minimize or survive the effects of disasters such as hurricanes, tornadoes, fires, and earthquakes. These disaster-resistant features are also focused on the building envelope and share many specific measures with high-performance, energy-efficient structures. The presentation will discuss how building science has evolved in researching and demonstrating solutions for high-performance energy-efficient homes versus disaster-resistant homes and how builders can draw on the results of both disciplines for superior results. The presentation will also discuss experiences with branding programs for both energy-efficiency and disaster resistant homes and efforts at changing building codes to improve baseline performance in both areas. And finally, this presentation will discuss the role that insurance companies may play in achieving changes in building practices related to high-performance, energy efficiency and disaster planning.
Dangers from more frequent extreme weather events represents growing concerns for building owners. This session explores how we can addressresiliency at the scale of buildings; topics such as Colorado-specific vulnerabilities, projected impacts, & mitigation strategies will be covered. The session will also discuss the inherent synergies between resiliency, sustainability & social equity.

The landscape of RESNET Quality Assurance has significantly changed in the past several years and efforts have ramped up to ensure consistency. The RESNET QA Team has doubled, field QA reviews began in 2018 and technologies like automated QA are being used. Scott Doyle, RESNET Technical Director of QA and Training, will share observations and findings from in-field visits with QA Providers in 2019. We’ll share the Good, the Bad, and the Ugly, including the RESNET QA Team’s favorite best practices and identification of Standard change needs, formal interpretations, and much more!
RESNET® and ACCA have teamed up to create a joint ANSI standard on the evaluation of mechanical system design and installation. The result has been the RESNET/ACCA ANSI Candidate Standard 310 “Standard for Grading the Installation of HVAC Systems”. The standard defines criteria and processes to grade HVAC designs and installations, including non-invasive tests. This new standard rewards high-quality HVAC design and installation with lower HERS® Index scores. We all know that the low hanging fruit in energy efficient building components has been picked. Standard 310 offers the lowest cost method of materially impacting a building’s HERS Index score because poorly designed and commissioned HVAC systems have a huge negative impact on a home’s energy consumption. Research shows that in some climate zones Grade I HVAC design and installation could reduce HERS Index scores by as much as 6 points.
According to recent MIT Research, residential efficiency offers the greatest potential to achieving carbon reduction goals. Yet an overly narrow focus on efficiency at the building level can lead architects, builders, and code officials to encourage the use of materials and technologies that could have the unintended effect of contributing more carbon to the atmosphere in the next 10-12 years--the critical time period outlined by the 2018 IPCC report--than they would save over that time. To meet this demand, the building industry must reduce the use of materials with global warming potential, such as steel, concrete, and refrigerant, and increase the use of materials that sequester carbon, such as wood and other plant-based fibers. We must also shift scales and metrics. We need to stop thinking about performance in terms of the efficiency of individual buildings. This framework emphasizes the reduction of waste and leads us to make buildings that are merely less bad. Instead, we should instead be thinking in terms of how neighborhoods can work together to utilize the surplus of available solar energy. This presentation demonstrates this potential through a proposal for the SunBlock developed for the final round of the 2019 Solar Decathlon Design Challenge. The project, though proposed for the Garden District neighborhood in Tucson, Arizona, is replicable in other low-density western cities with abundant solar energy. Different building types work together with air-to-water heat pumps set to run only when electricity is generated on-site. The neighborhood shares excess thermal energy through a district energy system of hot and cold water circulated in pipes buried in existing backyard utility easements. First, a big box store is retrofit to become a co-working space that exports heat. Second, an existing elementary school uses a large and already built PV array that shares chilled water at peak times and when it is unoccupied. These buildings share energy with existing houses in the nearby neighborhood. Those houses receive either a light energy retrofit including an insulated storage tank, or nothing other than a new air handling unit, which is connected to the plentiful carbon-neutral energy shared by the district system. Preliminary calculations indicate that for every three homes retrofitted and connected, the SunBlock system could provide for the heating and cooling needs of two more homes. While similar in intent to distributed energy storage systems that use chemical batteries to store electrical energy, the SunBlock proposal for distributed thermal energy storage is better equipped to reduce grid stress and reduce nighttime loads. Financing for the SunBlock is anticipated to be provided by a combination of public and private funds underwritten by utility savings, leveraged by tax advantages from the project’s location in a designated Opportunity Zone.
Building better homes is a great thing to do, but to be successful the sale has to happen. Expecting to sell higher performing homes by focusing only on the selling process, however, won't drive the results needed to sustain the business. To be successful you have to be all in. Being all in requires the building of a high performing business--one that has the right set of principles, priorities, and processes in place to thrive.
In this session, we discuss the transformation of the electric grid and how utility providers are modernizing their power generation and distribution systems. We explore the role solar power, smart meters, microgrids, energy storage and emerging technologies play in grid modernization (also known as smart grid). We highlight the benefits, challenges and opportunities a smart electric grid offers builders, citizens, communities and businesses.
Rachel Romero from NREL hosts an engaging session that makes presentations concise, keeps things moving at a rapid pace, and engages the audience in learning creative ideas! In this fun, innovative and informative session, the Solar Decathlon 2019 Design Challenge 1st place winning teams will present their winning designs and show how they will become the next generation of building science professionals through designing zero energy ready buildings.
This session will discuss structural failures observed during storm damage assessments as well as energy efficient design that contribute to improved overall performance in the structure. Developed independently from building requirements imposed in Moore, OK, following the tornado that devastated that community, APA’s recommendations focus on good connection details to tie together exterior walls, roofs, and floors. Included in this discussion will be construction techniques that also increase the energy efficiency of the house such as 2x6 advance framed walls and raised heel trusses. These techniques can help builders cost effectively build a safer homes in tornado and high wind prone regions that are also more energy efficient.
Back for another round! ** If it is so important to have a mechanical ventilation system to make a tight house healthy, what do you do when the power goes out? @You’re going to have more problems than just happy air flow if the power goes out. You’re not going to have heat or lights. And what about fungi? ** How long do you have to wait to clean up the excess moisture? @You shouldn’t wait. Fungi happens fast. ^^ And how many cfm does it take to adequately suck the air out of the basement to dissipate radon? @How do you know if a cabinet has formaldehyde?

Zero energy homes (ZEHs) are a big part of the future of the home building business. While the materials and equipment to reach zero energy are available, designers and builders must create a bundle of energy-efficiency features that matches their climate, customers, and business constraints. This 7-hour class lays out numerous elements of zero energy design and construction, so that building professionals can formulate a package appropriate for their situation. There is no one-size-fits-all solution. Students in this class will learn design principles, equipment options, emerging technologies, material selections, and construction practices that can be integrated into their building process. Strong emphasis is placed on ways to make the final product affordable for homebuyers. Sales and marketing ideas are also presented.
Since HERS Ratings and Third Party Certifications first became part of the residential new construction marketplace … building science has progressed at a pace that seems never ending. Mortgage lending … not so much. This has changed … on March 15th 2019, Kerry Langley (Sr. Mortgage Banker / HERS Associate) announced that United Community Bank will be offering discounted mortgage loans, thru their “Best Builder” program, to prospective buyers of high performance/zero energy ready homes. The discount, which is paid in the form a lender credit / rebate at the purchase closing to the buyer, can be applied to reduce the long term interest rate on the buyers loan, to reduce the buyers closing cost or to reduce the cost of the buyers mortgage insurance (if applicable). While lender credits/rebates are old news in the mortgage industry, it is typical for mortgage lenders to increase the interest rate charged and then rebate funds to the buyer, usually applied to their closing cost. What sets the “Best Builder” program apart is that it is built on a reduced cost structure, and so the lender credit/rebates are a true discount (not just a shell game).The lender credit/rebate is equal to 1% of the loan amount (capped at $4,000) and typically will reduce the interest rate on a 30 year loan approximately .25%. The session offered by Mr. Langley will be a review of the “Best Builder” program for high performance / zero energy ready homes and will include TCO (Total Cost of Ownership) financial modeling and real world examples that illustrate how using this program can greatly enhance the value proposition for builders who build above code. The examples will include how the program has been used to increase prospective buyers purchasing power, to decrease long term TCO, to enhance affordability and maybe most important of all, to show prospective buyers a head to head comparison of the TCO of owning a code built home vs. a high performance/zero energy ready home. If you build, sell, rate or provide supplies to high performance/zero energy ready homes … don’t miss this session, it’s a game changer!
Zero energy home construction is not beyond the reach of the average builder. Come to this session to learn how this year’s crop of DOE Zero Energy Ready Home builders achieved zero energy homes, and you can too. This presentation describes the path to zero offered by the DOE Zero Energy Ready Home program and provides a compilation of the techniques used by award-winning builders in DOE’s Zero Energy Ready Home Program to achieve HERS scores of zero and lower. Learn how the program is growing with more builders signing on just as more states and municipalities around the country are committing to zero energy ready construction. The presentation will show specific examples of techniques developed and used by builders as they strive for zero energy ready homes. Construction methods used by Zero Energy Ready homes are compared with those used in just-to-code new homes and existing homes for key components like wall assemblies and HVAC s
In this session, CR Herro, VP Innovation Meritage Homes, will discuss the building science, sustainable design, and green building features of the VISION House Seattle Cascades, a project he is developing in conjunction with Green Builder Media. The off-grid, net-positive, healthy home optimizes demand-side energy management and incorporates of the most advanced green building products, systems, and technologies available on the market today, all at a reasonable price point.
The goal of EPA’s WaterSense Labeled Homes program is to encourage the construction and purchase of water-efficient, high-performing homes that use of water- and energy-efficient products and include advanced design. The program aims to reduce indoor and outdoor water use in homes and encourage community infrastructure savings. Given the changes in building industry since the program was first introduced in 2009 and based on feedback from stakeholders, years of operational knowledge, and changes in the home building marketplace WaterSense released the WaterSense Draft Specification for Homes, Version 2.0, which aims to further promote residential water efficiency and help enable market transformation in the building industry. In parallel, RESNET has been developing the HERSH2O water rating index with the aim of creating a companion product to HERS for water, one of our most vital resources. Through this planned partnership, EPA and RESNET hope to establish a powerful link between WaterSense and HERSH2O. The session will highlight the anticipated changes to WaterSense Labeled Homes program and delve into how HERSH2O can contribute to the revised program’s efficiency requirement. Thus allowing the programs to work in concert with one another with the goal of creating a clear message about a home’s water use.
The goal of the WaterSense labeled homes program is to encourage the construction and purchase of water-efficient, high-performing homes that use of water- and energy-efficient products and include advanced design. The program aims to reduce indoor and outdoor water use in homes and encourage community infrastructure savings. On April 2019, WaterSense released the WaterSense Specification for Homes, Version 2.0, which aims to further promote residential water efficiency and help enable market transformation in the building industry. The specification is applicable to single-family homes and multifamily buildings. The U.S. Environmental Protection Agency launched the WaterSense labeled homes program in 2009 with the WaterSense Single-Family New Home Specification and issued modifications in 2012 and 2014 to expand the scope to multifamily buildings and include minor revisions, respectively. With this latest revision, WaterSense will expand the reach of the program, adapt to changes in the building industry, and increase flexibility so that a broader range of professionals can participate in the program.
The residential building industry has made incredible progress toward sustainability and energy efficiency goals. At the same time, HERS Rater and registered architect Steve Klocke finds many new buildings are underperforming because designers continue to make SIMPLE, AVOIDABLE MISTAKES. The affordable housing market in particular has the most to gain (and lose) when mistakes impact health, durability, tight schedules and tighter budgets. SMART DESIGN CHOICES yield buildings that are easier to build, resulting in lower costs, more predictable construction schedules, and higher quality buildings. Inspections, testing and commissioning become more successful, and most importantly, a building that incorporates smart design decisions is more valuable to owners, consumes less energy and is HEALTHIER FOR OCCUPANTS. Based on lessons he learned certifying nearly 1,500 dwelling units over the past eight years, Steve Klocke will present the top ten design mistakes being made over and over again - and how to avoid them.
How do we use data to formalize a regional performance path framework that allows any utility or home certification program to accurately capture savings or stay a fixed percent better than code? NEEA's BetterBuiltNW Program in the Pacific Northwest has been collecting data since its inception in 2004 and in this session, Dan, Jon, and Emily from the program will discuss how the data collected is used in various ways to support regional goals. From one angle, the program supports best practices and trains stakeholders on how best to achieve energy savings, and we'll discuss how that can influence code advancement. From another angle, the program looks at transforming the market for above-code homes and can identify both how far we've come and showcase market transformation success stories. Finally, the session will tackle what data our presenters recommend collecting to demonstrate success in your new construction program, as well as share recommended practices that could be applied to above-code construction accross the country.
Disability Adjusted Life Years (DALY) is a measurement of reduced healthy life developed by the World Health Organization (WHO). It is a measurement of the “gap between current health status and an ideal health situation where the entire population lives to an advanced age, free of disease and disability”. Many elements impact a healthy life one of which is indoor air quality (IAQ). IAQ is impacted by ventilation. This session will review the work done by the WHO and other organizations on DALY analysis and consider the value of mechanical ventilation to provide a tool for weatherization and healthy home programs to tie an economic value to the improvement of mechanical ventilation systems.
A focus on building enclosure and mechanical strategies and systems for high-performance Zero Energy Ready Homes. While solar systems can be bolted on later, it is not as easy to change the efficiency of the building enclosure or equipment. It is critical to find cost-effective approaches to get the loads low and efficiencies high. This will keep the cost of a renewable energy system -- today or in the future -- more affordable, too. But beware, approaching "zero" is not simply adding more of the same, it requires new approaches for many things including design, ventilation, make-up air, and humidity control.
