Building Science
SWA is among a small group of leading building science researchers dealing with this rapidly changing and highly challenging field. Using the systems approach that is the foundation of all SWA’s work is the only way to understand the complex interactions between the building site, 
envelope, and mechanical systems, as well as other factors. Emphasis is placed on sustainable/green
building strategies that result in the construction of healthy, durable, comfortable, affordable, and energy efficient, houses which incorporate appropriate materials, systems and technologies.
SWA works with the building trades to adopt an integrated approach to assessing, correcting and building residential structures. SWA recognizes that features of one component in the house can greatly affect others and it enables the incorporation of energy-saving strategies at little or no additional cost.
SWA has expertise in numerous fields, including:
- the resistance of structures to both natural and man-made hazards
- factory-built housing, and a breadth of design experience using modular construction, including steel-framed modules.
- various types of panelized construction, notably those based upon structural insulated panels, or SIPs.
- moisture control, mold, and indoor environmental quality
- solar thermal and electric systems
In addition to analytical work, SWA is able to provide laboratory testing, as well as short-term and long-term field testing for various studies.
