What is Passivhaus?
Passivhaus (or “Passive House”) is an internationally recognised standard for energy-efficient buildings. It focuses on creating homes that are well insulated, airtight, and designed to make the most of natural heat from the sun, people, and appliances. This means your home stays warm in winter and cool in summer with very little energy use. Passivhaus can also encourage innovative and exciting design, whilst working equally as well in a more traditionally designed home.

What are the Benefits for You the Home Owner?
