Touted as “the world’s largest passive housing” project, a 162 unit residential complex is currently under construction in Heidelberg, Germany. The solar-powered Heidelberg Village designed by the Frey Architekten firm will feature a wide range of sustainable features, as well as rooftop and vertical gardens. The complex is expected to use 75% less energy than a similar project using conventional building design.
The Passive design concept originated in Germany in the 1990’s, and has now been embraced worldwide as an effective and economic way to cut carbon emissions and reduce energy demand in buildings while still providing high-caliber living comfort, superior indoor air quality and structural resilience. While the movement began with a residential focus, passive “house” building principles have been adopted in major commercial building projects as well, setting new standards for heating and cooling efficiency, total energy consumption and air leakage.
One of the most ambitious “passive design” commercial projects currently underway is in Belgium where Europe’s largest passive office complex is under construction. The Herman Teirlinch government office will be a 66,500 square meter mixed use, low-rise, sustainable building designed by Neutelings Riedijk.
While entire passive home neighborhoods have yet to be created in the United States, passive design residential and commercial buildings are cropping up nationwide. The key components are 1) high-quality insulation and thermal-bridge-free construction 2) airtight construction 3) energy efficient windows and doors 4) mechanical ventilation for air quality.
Sto Corp has been a leader in providing passive design projects with energy efficient exterior insulation and finish systems. StoTherm ® ci continuous insulation, air moisture barriers, and advanced wall cavity systems have been used to meet and even exceed passive design energy efficiency standards in various climate zones across the country.
