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.

Learning Objectives:

• Discuss the importance of good filter placement/housing vs. MERV rating 
• Identify the top certifications and scores that may help convey the value proposition of good IAQ
• Reference current and upcoming resources for sourcing products and processes designed to maximize good IAQ beyond ventilation products 
• Recognize the value of system use vs design in reducing the risk of bad IAQ

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?”

Learning Objectives:

• Understand how off-site prefabrication construction approaches can overcome productivity and energy efficient buildings adoptions issues in US construction market.

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.

Recent energy efficiency practices have led to greater airtightness and insulation levels in houses, prompting concerns about interior moisture levels and comfort. At the same time there is growing industry interest in peak load management of large energy consuming home components. Constructing low-energy/ low-low homes and conditioning them with mini-split heat pumps (MSHP) have been common options in these overlapping conversations. But very little data exists comparing the desired outcomes of these paired technologies with the real-world results in the mixed-humid climate of the Southeast. Advanced Energy has been studying these systems in nine low-load houses in mixed-humid climates by sub-metering MSPHs and monitoring temperature and relative humidity measurements. Advanced Energy’s research indicates both desirable and undesirable outcomes from this field research. Some desirable benefits from these paired technologies include operational energy savings, coincident peak savings and low installation costs. Some undesirable outcomes include high indoor dew points, MSHP fans running when the coil is not below dew point, and design- and occupant-related issues.

Learning Objectives:

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.

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.

Learning Objectives:

• Understand how building design and construction affects HVAC equipment design and capacity
•  Define and describe what is meant by the terms “high performance home” & “low load home”
• Identify differences between traditional and high performance residential HVAC system components
• Understand how to control humidity in high performance homes and the benefits to occupants and builders.

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.

Learning Objectives:

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.

Learning Objectives:

• Builders will be introduced to the four control layers for high-performance homes and how these layers compare with control strategies for high-wind and high-rain events.
• Builders and designers will learn how high-performance specfications may be enhanced to improve disaster resistance.
• Builders, program managers, and building code professional will be introduced to comparions of adopted energy-efficiency and disaster-resistance codes.
• Builders will be introduced to plans to incorporate disaster resistance information in the Building America Solution Center (basc.energy.gov).

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!

Learning Objectives:

• Describe the three main ways in which RESNET Staff implements QA oversight of Rating Providers
• Share at least three "Best Practices" identified from 2018-2019 RESNET QA Program activites
• Understand the most common mistakes or misrepresentations made by raters and providers

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.

Learning Objectives:

• Builders will learn how to select mechanical designers, contractors, and raters to implement Standard 310.
• Builders will learn how to estimate the HERS point savings Standard 310 may provide for their plans and the estimated cost to implement it. Builders will also learn how Standard 310 fits in with potential 45L tax credits to achieve a dual return on investment.
• Mechanical designers will learn the design criteria established to qualify for Standard 310. Contractors and HERS raters will learn commissioning best practices to implement Standard 310 in their builder’s projects.
• Utility program managers will learn how Standard 310 impacts both total energy consumption and peak load to determine whether to incorporate the new standard into incentive and rebate programs that will have a material impact on grid performance.

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.

Learning Objectives:

• Understand the critical role of addressing refrigerant use intensity and other measures that can significantly reduce the global warming potential of projects in the short term.
• Shift their thinking from a focus on efficiency and the reduction of waste to a new focus on the potential of surplus energy and sharing.
• Discuss the basic principles and potential of neighborhood-level district energy systems.
• Begin to identify the network of partners and work required to bring a project such as the SunBlock to fruition.

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.

Learning Objectives:

• Why focusing on sales will, paradoxically, lead to poor performance.
•  What separates the great companies from the wanna-be's. 
• How to get and keep your team focused on the right principles, priorities and processes to drive success.
• What are the two most critical KPI's you need to measure and why?

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.

Learning Objectives:

• Identify factors that are driving the U.S. housing market toward zero energy homes.
• Name barriers to the widespread adoption of zero energy homes.
• Describe three ways to present the financial benefits of zero energy homes.

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!

Learning Objectives:

• Develop an understanding of how looking at the financial side of high performance / zero energy ready homes must include an analysis of Total Cost of Ownership (TCO). 
• Develop an understanding of new “Best Builder” program and how is enhances the value proposition of a newly built high performance/zero energy ready home. 
• Develop an understanding of how TCO-Flex Choices gives a builder control over how his sales concession dollars are used and how he/she can use them as an affordability tool or a marketing advantage over their competition 
• Develop an understanding of how increasing home prices & interest rates “price out buyers” and what a builder can do to mitigate this in their markets.

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.

Learning Objectives:

• Participants will learn how WaterSense Homes program structure for the latest WaterSense Labeled home specification differs from previous versions.
• Participants will have a better understanding of the new water efficiency thresholds and how to achieve them under the new WaterSense Labeled Homes 2.0 specification.
• Participants will learn the basic structure of RESNET's numeric water efficiency rating system for homes, and its similarities and differences from the HERS rating system.
• Participants will learn to identify the specific features and attributes of a home that will influence its numeric rating for the water efficiency.

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.

Learning Objectives:

• Understand how the revised technical requirements provide more flexibility and better quantifiable water savings.
• Learn how the program will work in concert with existing green building certification programs.
• Understand the process of obtaining the WaterSense label for Homes under Version 2.0.
• Learn how the WaterSense Specification for Homes, Version 2.0 has improved regional applicability.

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.

Learning Objectives:

• List the top ten design mistakes by architects and engineers that decrease constructability, affordability and quality of multifamily housing.
• Choose design choices from a selection of scenarios that increase energy efficiency, building durability, occupant health and affordability.
• Justify design alternatives to clients and contractors in terms of energy, durability, health and budget.
• Develop a checklist to help you make design choices that increase energy efficiency, building durability, occupant health and affordability on future projects.  

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.

Learning Objectives:

• Learn about how best practices yield savings, and how this can be used to advance code
• Learn about Home Certification Programs, their parameters, and how a region-wide program can help expand their footprints
• Learn about the role of software platforms in collecting data points that will ultimately help drive market transformation
• Learn about the data that is used to support integrated resource planning at the regional level

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.

Learning Objectives:

• Learn about the DALY as a metric for health;
• Appreciate some of the factors that impact health in houses;
• Gain an understanding of the connection between ventilation and long term health;
• Appreciate the value of an effective mechanical ventilation system.

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.

Learning Objectives:

• Familiarity with the concepts and definitions for high-performance and net zero energy homes.
• Be able to apply basic building science principles to building and systems design.
• Recognize key enclosure and mechanical strategies for cold climates with summer cooling loads.
• Recognize the critical need for pressure management.
