The international Passivhaus standard is the world’s leading standard in energy-efficient building design. In this article, Passivhaus designer Es Tresidder of HighlandPassive.com explains why you should consider going for Passivhaus certification for your new-build or retrofit project, and how you should go about it.
The Passivhaus standard is well known as an energy-efficiency standard, and it certainly does that well – Passivhaus-certified buildings typically require 90% less heating than existing buildings, or 70% less than typical new-builds (think annual heating bills of around £100 for a 2-3 bedroom house, for the house being warm 24 hours a day). They achieve this through high levels of continuous insulation, high-quality triple glazing, airtight construction and careful design and attention to detail.
