House Notes – Nantes House

This is a new home built after many years in the planning. The goal was to create a warm, bright, airy and comfortable but low energy home in which my wife and I could enjoy our retirement. We were able to do a lot of research and were then closely involved in the design and construction. The combination of north facing glass, careful insulation and a large amount of thermal mass means the house requires no heating except on overcast days in the coldest months of the year, while typically maintaining a comfortable 20 to 23C. The house is all electric and with 10kW of solar panels will be a net exporter of energy over the year.

This house achieved a NatHERS rating of 7.3 stars using NatHERS accredited software. Find out how the star ratings work on the Nationwide House Energy Rating Scheme (NatHERS) website.
