Research & Development

SWA conducts ongoing research and development projects with both public and private sector partners and is among a small group of innovative building science research firms shaping this rapidly changing field. We use the systems approach to measure and assess the complex interactions between the building site, envelope, mechanical systems, and other parameters. Working with the building trades, we maintain an integrated approach to constructing, assessing, and correcting residential structures.

SWA has collaborated with product manufacturers to evaluate, develop and bring to market innovative building products, materials, and systems. Our mix of hands-on technical experience, testing capability, understanding of product development and marketing, coupled with our extensive network within the building industry results in a highly focused and efficient collaborative process.

Published Study: There Are Holes in Our Walls
The UGC selected SWA to produce a research paper on the impact of room air conditioners on building envelope performance. SWA’s Multifamily team conducted the study and authored the paper, finding that an average room AC accounts for as much air leakage as would a six square inch hole in the wall; room AC leaks add $130- $180 million to New York City heating costs every year.

Building Energy Efficiency Data Report
This newly published study shows the clear benefits of retrofitting existing multifamily buildings.  SWA building scientists and database experts conducted the research, while partners HR&A parlayed the information into financial and real estate terms.  This 18-month analysis of 19,000 New York City housing units details the significant economic and energy benefit of even modest retrofits. The study aims to provide the statistical underpinnings necessary to encourage private investment in sustainable, energy-efficient upgrades to existing multifamily housing stock, thereby revolutionizing an already dynamic new business sector.
