Trans-Atlantic Transformations: Challenges of Translating Successful High-Performance Building Technologies Across Continents.
41st IAHS World Congress on Housing, Albufeira, 13-16.09.2016, [Conference or Workshop Item]
Abstract
Climate change, resource availability, and subsequent energy efficiency in buildings have become international focus areas of research and policies, which are addressed differently in countries east and west of the Atlantic divide. This paper examines challenges and opportunities of transferring successful high-performance building programs, such as Low-Energy homes or buildings built to the PassivHaus standard in Germany and Net-Zero standard buildings in the United States, to their respective opposite continent. The paper discusses the different climate response strategies observed in design and construction, the differences in resource availability and pricing, and other factors that challenge a quick transfer and application of utilized technologies and design processes to the other continent. Specifically, thermal and hygro-thermal performance as they relate to moisture control in residential enclosure systems, have been identified as critical components that require further research to prevent future issues with changes in climate and new material technologies. Significant differences in solar radiation and electricity cost lead to different prioritization of technologies, which in turn lead to prevalence of different system configurations, which vary between the two continents. While some systems, such as high-performance windows have entered the U.S. market, there are still challenges in terms of competitiveness and availability. Lastly, occupant expectations and preferences, a vastly different real estate landscape, and differences in socio-economic context provide additional barriers to a direct transfer of technologies even though both countries have established successful flagship programs.
