FXFOWLE Architects will undertake a research study to determine the viability of implementing the Passivhaus standard on tall residential buildings in New York State. Using a 25 story multifamily project currently in design as a base building, the study will investigate the detailed implications of adapting a typical tall residential building to meet the Passivhaus standard. This work will analyze the impacts from architectural, structural, enclosure detailing, materials, mechanical, zoning, financial, marketability, and constructability perspectives. Market barriers and opportunities will be identified and addressed. In addition, the study will evaluate how applying the Passivhaus standard to a tall multifamily residential building can affect resiliency and security issues

Evidence in a new, groundbreaking Energy Department report, Home Rx: The Health Benefits of Home Performance, shows that home performance upgrades can improve the quality of a homes indoor environment by reducing the prevalence of harmful indoor air pollutants and contaminants. This paper is just one part of the Energy Departments broader Health and Home Performance Initiative. Another step will be to develop messaging that home performance programs, contractors, and partners can use to communicate clearly about the health benefits of home performance work with consumers and stakeholders.

The next step for the Initiative will be to engage with stakeholders to develop a roadmap to facilitate the home performance industrys incorporation of healthcare into their work. Workshops are slated for conferences in January, March, and May 2017.

BPA is seeking to expand multifamily energy efficiency incentive offerings for new and existing construction. The goal is to identify and work out the technical challenges associated with integrating technologies into multifamily buildings.

High performance, low-load homes face unique space conditioning challenges that are not adequately addressed by HVAC design practices and equipment offerings. Equipment manufacturers have yet to include a diverse set of low-capacity equipment in their product offerings due to a lack of understanding of (1) where the low-load home market is headed and (2) the load profiles typical to low-load homes. This project looks to address both of these information gaps and ultimately send the necessary low-capacity equipment market signals to manufacturers, enabling them to design better products to meet production builder needs. The team will develop a technical whitepaper and presentation on the performance and cost tradeoffs of various equipment types/systems at meeting the comfort requirements of low-load homes, and forecasting the market penetration and equipment needs for these low-load homes.

The National Renewable Energy Laboratory will work to significantly increase the capability, cost effectiveness, openness, and reach of the Residential Buildings Integration (RBI) programs tools and analysis methods to accelerate the adoption of zero energy ready homes.

International Center for Appropriate and Sustainable Technology will expand its one-stop-shop model to address the Small Commercial Apartment Property market with deeper retrofit. Using the model is expected to cut energy use by 20-30% in small commercial apartment properties, reduce individual building utility bills by $3,100 annually, and create 200 jobs.

This project researched new phase change materials (PCM) to store thermal energy for wall assemblies, and develop associated software tools. Heat is absorbed or released when the materials change from solid to liquid or vice versa. PCMs absorb thermal energy and they can reduce the need for heating and cooling in some buildings. Their impact is similar to that of adding thermal mass to the building. Unlike air conditioning systems, they require no maintenance. The use of PCMs and associated software tools can contribute to zero net energy commercial buildings by reducing the energy needs of a building through passive design.
