Tackling cold homes: a national infrastructure priority?

Rather appropriately on Cold Homes Week ministers have been told that reducing the number of cold, leaky houses in the UK should be made a national infrastructure priority. It seems there is now widespread, cross-party support for this. While this will feel like old news to us at Parity Projects and many of our industry […]

EPCs

Home Energy Audit / Assessment, Retrofit Design Services, Energy Performance Certificate; which one do you really need and how do you see through the jargon?

With the amount of organisations out there offering ‘energy audits’ or ‘energy assessments’ these days, particularly since the demise of the Government’s Green Deal scheme, it can be difficult to know where to start looking if you’re a homeowner. While we are yet to come across a service that offers the value of our own […]

A record breaking home! Energy figures for 2015

Ok, so its our own record, but we’ve had the lowest calendar year energy usage for our demo house so far. I’m putting it down to 3 changes over last year – a) slightly lower occupancy with the children being out at school b) a very mild 12 months c) some remediation work to some […]

A review of ‘Solid Wall Insulation: Unlocking Demand and Driving up Standards’ , Peter Hansford, Chief Construction Adviser to the UK Government.

It was […]

Some thoughts on low energy retrofit this autumn

Having spent most of last week working in the Lake District I can tell you that for some that time is already […]

Comparison to Passivhaus – update

Way back in September 2013 we posted a piece comparing our demo house to Passivhaus and Enerphit.  I’ve provided updated figures here based on our actual bills for 2014: The figures pretty much speak for themselves. Remember, we didn’t follow Passivhaus, we just followed sensible principles, worked out the cost effective solutions applicable to our house, […]

Renewable Heat Incentive for our Demo House

I eventually got round to applying for the Domestic Renewable Heat Incentive for the solar thermal system on our demo house. We’d previously received £300 from the Renewable Heat Incentive Premium Payment which rightly reduces the amount we will received. (not the best picture but the solar thermal is in the middle on the flat […]
