The following are the session descriptions for the
EEBA High Performance Home Summit:
Water was once an afterthought in the modern built environment. Spurred by extreme drought, infrastructures concerns, and an innate comprehension of the importance of this vital resource, water no longer falls into that category. Using water effectively has been become a primary challenge for those in the building/construction, management, and buildings science fields. This session will explore not only cutting edge technologies and techniques for using water efficiently, but also the underlying drivers that are creating changes to law, code, and user expectations.
• Articulate several major drivers that are impacting water use through policy, code, and practices • Recognize trends in the building industry that are impacting water use • Understand how practices over time and across regions have influenced homes and water buildings • Identify several emerging trends in technology and management practices that can help address water use in homes and buildings

The 2018 IECC laid out a prescriptive path for the use of buried ducts with fibrous insulation in vented attics, for all climate zones. This new path was approved because it will allow builders to get much of the energy efficiency benefits of an unvented attic with closed cell spray foam by instead doing a traditional vented attic with the ducts buried in fibrous insulation.
While the practice of burying ducts is not new everywhere, having prescriptive code language is. This includes guidance on how to design and install buried ducts in hot/humid climates. The code change, which was the result of an NAHB amendment that had broad support, has potential to provide a vented attic design that is highly energy efficient but at lower cost than unvented attics.
1. A detailed summary of the code changes. There are variants of buried duct approaches with different code, and energy modeling, implications.
2. A description of how builders can use this practice today, even if their area is not yet on the 2018 IECC.
3. An overview of the energy and cost benefits of this approach compared to traditional or unvented attic design.
4. A synopsis of relevant field research proving out this practice by showing how it can be done effectively, and safely, in all climates, even hot/humid ones.

When companies strategically choose to cooperate to accomplish shared objectives, everyone benefits from leveraging shared resources, skills and knowledge. Collaboration is critically important when executing programs or initiatives that have a high level of uncertainty, complexity and risk. The building of higher performing homes contains all three of these elements, making collaboration an imperative for any builder that chooses to chart a better course.
In this session you will learn:
the critical elements for creating and sustaining successful collaborations, the benefits from collaboration and how to prevent a failed collaboration.
Lab and field studies have demonstrated that central air conditioning and heat pump systems are installed with faults and errors as often as 50% of the time, including duct leakage, refrigerant undercharge/overcharge, oversized systems with nominal ductwork, improper fan speed, and low airflow, among others. This results in up to 30% reduction in efficiency right from the start, in addition to comfort complaints for homeowners and callbacks for contractors. A new breed of “expert” automated validation systems (AVS) provide quantitative capabilities to commission systems at start-up by performing system diagnostics and coaching the installer. They also provide reporting and alerts through fault detection and diagnostics (FDD) to both the homeowner and dealer for the life of the equipment. This session will explain how two different AVS work, including what is measured, what is computed, and what feedback is provided to the HVAC technician. A live demo is included. It will also discuss how these systems are being used to verify proper HVAC installation for ENERGY STAR and utility programs. Importantly, presenters will also share feedback from HVAC dealers who are using AVSs, including impact on callbacks, installation time, and repair scheduling.
1. Dealer benefits to using an AVS for both commissioning and ongoing monitoring and alerts.
2. Homeowner benefits to using an AVS.
3. How to sell an AVS.
4. How internet of things (IoT) is enabling increased control, efficiency and comfort from HVAC systems.
Anyone can build an energy efficient or net zero home with unlimited funds, but for most projects, funds are limited. The challenge is how to assess where to most effectively put you energy saving dollar, and when does it no longer makes sense. With energy modeling tools at our disposal, we can answer this question.
With the cost of PVs coming down, getting to net zero energy use is now a realistic goal. Understanding when to stop investing in energy savings and when it is better to invest in energy generation is now the responsibility of designers.
Using several recent net zero and energy efficient projects as examples, Mr. Rahill will demonstrate a simple methodology for determining where best to spend your energy saving dollar, how to balance the investments among components and when to stop, using recent net zero and other energy efficient projects as examples.
1) Participants will understand the critical principles behind net zero design.
2) Participants will learn how and when to maximize energy savings through insulation, daylighting, and efficiency mechanical and electrical systems.
3) Participants will understand the opportunities and challenges of different power generation options.
4) Participants will understand the importance of balancing energy savings and generation.

This session will discuss the overall objectives and interim results of a Building America project focused on integrating a new technology for automating the building sealing process in new homes. The process involves briefly pressurizing the building while applying an aerosol sealant “fog” to the building interior. As air escapes the building through leaks in the envelope, the sealant particles are carried to the leaks where they impact and stick, sealing the leaks. A standard blower door is used to facilitate the sealing process, and provide real-time feedback and a permanent record of the sealing. The technology is thus capable of simultaneously measuring, locating, and sealing leaks in a building remotely. Demonstrations of the technology have been very successful typically sealing 80% of the sealable leakage in under two hours of injection.
The Building America project will provide significant research needed to successfully integrate aerosol envelope sealing into the home building process. The project team is working directly with builders to identify the best stages for incorporating aerosol sealing, from the perspectives of cost, performance, and seamless integration into the construction process. The cost of the aerosol sealing and resulting house tightness are compared to similar group of houses using conventional sealing methods. In addition to producing tighter houses, conventional sealing methods are evaluated to determine whether they can be eliminated or reduced to further improve cost effectiveness. This talk will present the results of the initial sealing demonstrations for builders in California and Minnesota.
At the end of the session, participants will be able to:
• describe the aerosol sealing approach for automating building envelope sealing
• compare the performance of aerosol envelope sealing to manual sealing strategies
• identify appropriate stages of construction where aerosol envelope sealing can be applied
• identify manual sealing efforts that can be eliminated when applying aerosol envelope sealing

New homes use less energy and water than their standard counterparts. But as envelopes, HVAC equipment, and lighting have become more efficient, heating water is a significant target for reducing a home’s energy and environmental footprint. Across the nation, consumers and utilities are targeting heat pump water heaters as the high-performance option for supplying hot water. The technology has been around long enough to be a proven performer, and recent innovations have enhanced reliability and performance. This technology provides benefits to consumers and utilities looking to save energy and enhance grid performance, and to state and local planners concerned with carbon emissions and other environmental effects. As consumers become more aware of this technology, and utilities and agencies continue to promote it, builders have an opportunity to improve their high-performance brand by adding heat pump water heaters to their product design. This session will describe key HPWH technologies, who manufactures them, tips on installing them, and the latest advances. The value of installing HPWHs to consumers, utilities, and local government planners will be described. The HPWH supply chain will be described, including topics such as product distribution and availability. Product cost and economics will be covered.

Attend this session for the latest information on new and improved Building America design tools that can positively impact how you design and construct homes. Oak Ridge National Laboratory will describe the Building Science Advisor. This innovative new design tool puts building science expert advice in the hands of every building designer who cares to manage moisture risk in high-R walls. As modern buildings become increasingly more airtight, constructed with modern labor-saving materials, and equipped with air-conditioning, they have become less forgiving to moisture intrusion. The Building Science Advisor (BSA) will provide building science knowledge and advice based on expert experience, field measurements, laboratory tests, and probabilistic computer simulations. Pacific Northwest National Laboratory will show attendees how to bring best practices for high performance homes into their construction practices with the U.S. Department of Energy’s Building America Solution Center. The Solution Center applies extensive, up-to-date building science content to specifications, field applications, training, working with code officials, and selling homes. These best practices are based on research generated by DOE’s Building America program.
• Builders and raters will understand how to access free best practices content within the Building America Solution Center, including: installation guides, CAD drawings, sales information, and code briefs. • Builders and raters will learn to use Solution Center technical support to train crews to install the measures needed to comply with labeling programs such as Zero Energy Ready Home, ENERGY STAR, Indoor airPlus, and WaterSense. • Designers will be introduced to the principles of moisture management in wall assemblies. • Designers will learn about a new design tool to help them apply expert building science advice in designing and evaluating the ability of high performance walls to manage moisture.
Many of us in the high-performance building world secretly feel a lot more comfortable designing and building a high-performance home than marketing and selling one. Or perhaps you feel like you’ve been building high-performance homes for a long time, but today’s homebuyer doesn’t care that much about what you’re doing? Or maybe you feel like the competitive market for land opportunities is putting you at a disadvantage compared to code builders? Hear real-world experiences from people who are successfully selling and marketing high-performance while building their brand and their business.
• Understand what the latest market research is telling us about today’s buyers and how you can apply these lessons in your sales and marketing program
• Discuss the delicate balance of educating prospective customers about the unique attributes of your high-performance home without “feature dumping”
• Learn how high performance building can help you grow opportunities for your company
• Hear perspectives on how to get your brand and marketing message supporting your efforts to sell high performance
Quality is not easily defined nor is it easy to quantify. That is, until you hold back $4,500 a home in order to pay for anticipated future failures and realize that’s exactly what you’ve done. Of course, it makes more sense to invest proactively in quality – in doing things right the first time – than it does in bleeding away already tight margins long after the home is delivered.
How much are you holding in reserve to pay for warranty claims, defects, and litigation? In this session, we will explore a model that “flips the script”—identifying the opportunities that come from investing those dollars in better building and management practices to achieve reliable profitability and boost buyer satisfaction.
Last year, IBACOS asked builders and developers to put some real numbers behind the Cost of Quality – a methodology that enables an organization to quantify how much they spend on quality-related costs and why. We received feedback from 21 companies during the initial study. In this session, we will present our findings on where the opportunities for savings lie in the areas of value engineering, construction oversight, cycle time, cost variance, customer engagement, warranty, employee satisfaction, trade/supplier loyalty, training value/valuation, documentation and execution.
By investing in quality, you can keep real money in your pocket. Money that you can plow back into your business, hire and keep the best people, grow your operations, or have on-hand to weather whatever storms may come your way.
1. Learn what 13 public builders have set aside (on average) to cover anticipated warranty an litigation costs
2. Understand how to quantify the cost of quality spent within your business.
3. Discover where potential opportunities for savings lie in the areas of value engineering, construction oversight, cycle time, cost variance, customer engagement, warranty, employee satisfaction, trade/supplier loyalty, training value/valuation, documentation and execution.
4. Identify the opportunities that come from investing dollars typically set aside for risk and litigation into better building and management practices.
Venting attics in hot humid climates leads to condensation especially with tile roofs, cool roof claddings and radiant barriers. Creating conditioned attics with low density and high density spray foam is one established approach to address the issue. However, there have been issues with the use of both low density and high density spray foam and other technologies have been developed. This session will look at using cellulose and fiberglass insulation in unvented attic assemblies in both cathedralized and uncathedralized geometries and address the issues associated with low density and high density spray foam.
1. How changing the energy balance of the roof assembly affects condensation in vented assemblies.
2. How condensation can be controlled by eliminating ventilation.
3. How to address the moisture balance in roof assemblies by increasing moisture removal that does not rely on dilution ventilation.
4. How to address the durability issues associated with low density and high density spray foam in cathedralized assemblies.
The U.S. Department of Energy (DOE) has been providing half-day seminars on Zero Energy Ready Home (ZERH) all across the country. Our favorite part of these seminars is what we call the ‘Voice of the Builder.’ Right after introducing ZERH as a powerful business solution, a few local builders who construct ZERHs tell their story. It’s one thing to listen to outside experts; it’s a completely different experience listening to local competitors who are among a select group of leading builders delivering a superior homeowner experience. Their journey to zero and lessons-learned along the way are incredibly important. This session will feature a select group of Housing Innovation Award winning ZERH builders to share what their wisdom leading the industry to zero.
For a leading group of builders:
• What business factors are driving them to lead where others wait and watch?
• What technical solutions allowed them to cost-effectively meet rigorous guidelines for outstanding home-performance?
• What marketing messages, tools, and strategies enable them to effectively engage homebuyers?
• What mistakes have they made that other builders need to avoid?
• What plans for the future do they have based on all that they have learned?
What is Demand Response and how does it fit in with building energy efficient new homes? As an industry we have focused on energy efficiency (EE) measures that provide additional non energy impacts (NEIs) such as comfort, durability, and IAQ. Due to a variety of source energy and site usage trends however, the needs to help shift loads and flatten load curves has become a real and pressing issue for utilities and municipalities. This session will look at how these trends may impact program designs, incentives, and product offerings that add a NEI that benefits utilities instead of homeowners. How can that work for us as an industry? How can we pass along or sell these benefits to homeowners? What products and processes provide both demand response and energy efficiency benefits?
1. Understand the basics of the "duck curve" for utility planning and evaluation
2. Discuss how time of use for power can impact and shape loads
3. Recognize the technologies and applications that can provide demand response opportunities in Residential New Construction
4. Engage in the discussion of unique value propositions for homeowners, builders/contractors/Raters, and utilities in participating in demand response savings programs.
