Why Design Matters
Second + Delaware is the World’s Largest Passive House Building
Second + Delaware embraces the best of history and forward-thinking design by utilizing the world’s leading standard in energy efficient construction called Passive House.
To many “Passive House” is a new concept. At the fundamental level, a passive house is designed to be extremely energy-efficient so that it doesn’t take a lot of power to heat or cool. To be designated as a Passive House, a building must embody a set of specific best practices that seal it from outside temperatures, while maintaining a stable inside temperature and high air quality.
Early 20th century residential buildings in big cities featured large, protected, landscaped courtyards where urban homes were oases to escape the hustle and bustle of the city. Second + Delaware builds on that model and includes best practices in energy efficiency and long-lasting construction for residents’ ultimate comfort.
As a result of implementing Passive House design and construction methods at Second + Delaware, our community consumes 90% less energy. The triple-glazed windows and 16-inch walls provide a pleasant, interior temperature year-round. When scaled globally, the design concept of Second + Delaware has the potential to remove 10 billion tons of CO2 from the atmosphere annually - a meaningful step to solving global climate change.
