The Lowell House ended up not only becoming Passive House certified, it also achieved LEED Platinum certification, as well. Below, you’ll learn more about these standards.

Passive House

Ever wondered if the heating or air conditioning in your house is really necessary? Passive House (aka Passive Haus) is a design approach to building that reduces the energy required drastically. According to, Passivhaus (or ‘Passive House’) is the fastest-growing energy performance standard in the world. Comfortable, healthy, sturdy, and affordable, a Passive home performs 60-85% better than its traditionally built counterparts and is one of the greenest home designs available. But even a traditionally-built home can benefit from Passive features, such as passive windows and renewable energy sources. Learn more by watching this 90-second video.

LEED, or Leadership in Energy and Environmental Design, is the most widely used third-party verification for green buildings. LEED-certified buildings are resource efficient through water and energy use reductions and they also reduce greenhouse gas emissions. Materials used in LEED-certified buildings are safer for human health and designs are aimed at improving indoor environmental quality for the occupants. Not only do they help protect the environment and human health, they also save money.
