Built in 2009 as Zero carbon housing was starting to take shape these Logix homes prove what can be done to save energy and CO2 on tight budget.
The Client’s view:
“These were built to rent out, so low maintenance costs and long term performance were important to us, but we also wanted to build something that uses as little energy as possible.
Planning restrictions meant that we couldn’t use any roof mounted technology to generate energy, no solar panels or wind turbines here, so insulating properly was only option.
We wanted to create a thermal envelope around the house. We also knew that due to the orientation of the site achieving a certified Passivhaus design would be difficult.
We set out to follow Passivhaus principals, in terms of ensuring the building was as well insulated and air tight as possible, and using Logix ICFs made that easy for us.
We combined the Logix walls, with triple glazed windows, concrete floors and a sips roof, and were delighted to match the Passivhaus target for air-tightness at our first attempt.
With a very low predicted heating demand we chose to use a combined MVHR and air-source heat pump system, from Genvex. Which eliminated the need for UFH or radiators.
Having completed the builds the real vindication or what we achieved has been the running costs.
Without any solar panels, these homes exceed the Passivhaus standard for heating, and primary energy use, costing less than £8/ month to heat.”
