Personal story:

I became interested in environmental issues in the early 80’s following a period working in developing countries. Subsequent projects included an early insulation project in a solid walled house, cycle campaigning, and environmental jobs, working for a local authority Sustainability team before recent retirement.

Motivations:

80’s inspiration came from Granada TV’s “House of the Future” programme, sort of a cross between It’s not easy being Green and Grand Designs. Airtightness and thermal bridging were not even known about then!

More recently, part of my Sustainability work was to keep up to date with greener building methods, and I learned about Passivhaus, Code levels, airtightness, thermal bridging/bypass and how they could be applied to existing homes. This inspired me to start testing some newer methods and materials in my current house with a view to it being more energy efficient and cheaper to heat. As the building is “hard to treat” and has an exposed northern aspect I hoped it could become a local example of what can be achieved on a limited budget.

Property background:

An 1890 end and corner terrace building, of stone and brick construction. It used to be a corner shop, and the diagonal shop door faces due north, making its situation very exposed to the Pennine winds and rain, with minimal solar gain.

Key changes made:

Timber triple glazed double sealed doors and windows on NE and SE sides. U values 1.00 or below. 2 small A rated double glazed UPVC windows on NW side, above shop window.

Internal Wall Insulation to all external walls, comprising 80mm Celotex, plus TLX multifoil with 25mm air gap both sides, thermal break between 4 x 2 timber battens and walls, taped edges between Celotex & battens.

Loft insulation: Topped up to 270 mm fibre insulation.

Floor insulation: Living room – 6mm plus hardboard under carpet underfelt, laid on new asphalt base. Upstairs floors – edge to masonry partially sealed & insulated, fibre insulation installed to limit of reach under floorboards.

Ceiling insulation: 25mm polystyrene within timber tongue & groove kitchen ceiling, partial fibre insulation under first floor floorboards.

Airtightness tape (Tescon Profil) and/or Orcon sealant used at all joints from new windows & doors to building fabric/edge insulation/vapour permeable membrane, to achieve optimum available airtightness & thermal breaks. Similar treatment at edges of walls, floor joints & some ceiling joints. Other doors draught stripped.

Kair single room heat recovery ventilator fitted in bathroom.

Alpha A rated boiler with Gas Saver heat recovery unit, new TRVs on all radiators, programmable TRVs in 3 upstairs rooms to achieve timed zone heating.

Measures installed in detail:

  • Internal wall insulation
  • Triple glazed doors & windows
  • Airtightness & thermal breaks improved
  • A rated boiler and gas saver heat recovery unit
  • Single room heat recovery fan
  • Partial floor insulation
  • Loft insulation increased to 270 mm
Benefits of work carried out:

Attention to details such as airtightness and thermal bridging, along with insulation to the best practical standards and triple glazing at key points, has produced a “whole house” solution to what was a typically inefficient building of its age. Heat recovery is the only technology applied on top of basic building efficiency, and this maintains comfortable humidity levels despite being in a single room.

The most obvious benefit is a large reduction in gas bills – the annual cost is less than half what it was before doing the work, and this period included big increases in tariffs (for comparison, I had stayed with the same gas supplier over the main work period of late 2010 to late 2013). Other benefits are a house which warms up quickly and cools down slowly; a much quieter house, mainly due to the triple glazing; and a very comfortable house in hot summer weather, which may be a result of the multifoil insulation reducing radiated (sunshine) heat gain. The triple glazing helps in this respect too.

Favourite feature:

My favourite feature is the combination of all the features working together, so it’s hard to identify a favourite. Using the triple glazed, double sealed doors to shut out cold and wind is a pleasure, as is returning home after several hours to find that rooms are still warm from earlier heating (which is due to the combined features, including invisible insulation and airtightness features).
