What Houzz contributors are saying:
Starting from scratch? Consider a Passivhaus Last but definitely not least, is the much talked about Passivhaus, or passive house, standard. A pure Passivhaus is unlikely to be an option unless you’re building a new home from scratch, but there are plenty of ideas to steal and retrofit. Born in Germany and the Scandinavian countries, the Passivhaus is a contemporary way to build very airtight houses, where all incoming air is warmed up by the stale air before being pushed out. Thermal efficiency exceeds all current building regulation norms. To adopt the key idea behind this new way of thinking, try to combine thermal insulation and heat recovery (see the points above about heating and insulating), then you will be one big step closer to a true passive house. When you apply these principles to an existing house, you might not get the same results, but it will be a big improvement nonetheless. A lot of the success of the Passivhaus comes down to the many ingenious details geared towards making the property more airtight and reducing so-called ‘cold-bridging’ – in other words, addressing the heat loss that occurs where different materials meet, a detail that has frequently been overlooked in other types of building.TELL US…Do you have plans for green upgrades to your home?
