Personal story:

I have always been interested in energy efficiency – both professionally, in working at the Building Research Establishment, and personally. So in 2009, I leapt at the chance to overhaul a tired Victorian terrace and improve its energy performance by installing insulation, a condensing boiler, and new windows and doors. These improvements didn’t just improve efficiency, but also added comfort.

Motivations:

– Reduce energy consumption

– Save money

– Improve thermal comfort

Property background:

I have always been interested in energy efficiency – both professionally, in working at the Building Research Establishment, and personally. So in 2009, I leapt at the chance to overhaul a tired Victorian terrace and improve its energy performance by installing insulation, a condensing boiler, and new windows and doors. These improvements didn’t just improve efficiency, but also added comfort.

Having been involved in authoring “Best Practice” publications for Energy Saving Trust whilst working at the Building Research Establishment, it was a good opportunity to implement recommended energy efficiency improvements. I mainly achieved this by applying insulation to the walls (internally), solid and suspended floors, and the roof.

I was particularly interested in optimising the performance of the new gas condensing boiler, which I connected to an OpenTherm compatible compensating control in order to minimise the average flow and return temperature to maximise condensation and therefore efficiency. More importantly, I designed the heat emitter (radiator) system for a maximum flow temperature of 55°C, which is much lower than common practice.

Creating a low-energy home isn’t just about efficiency, it’s also about comfort. A home without draughts or coldspots – especially a Victorian home – is not only a luxury – it’s a rarity. In order to achieve this I fitted good quality double-glazed period timber windows that feature double-seals and ensured all penetrations, gaps and details were properly sealed to maximise airtightness. Due to the low U-values (heat loss) achieved through applying insulation to walls, floor and roof, the home is very comfortable throughout the year.

Key changes made:

Windows new double/triple glazed Replaced throughout with double glazed timber sliding sash to front and tilt & turn (sliding sash effect) to rear (U-value = 1.4 W/m2K). Plus insulated panel timber front door.
Internally or externally insulating external walls (including cavity fill) Internal PIR insulation (100mm, average U-value = 0.210 W/m2K) throughout (insulated plasterboard)
Loft insulation 50mm PIR Insulation + 245mm Mineral Wool (75% area with U-value = 0.116 W/m2K); 150mm PIR Insulation for vaulted ceilings (25% area with U-value = 0.177 W/m2K). Airtightness measures included.
Roof insulation 50mm PIR Insulation + 245mm Mineral Wool (75% area with U-value = 0.116 W/m2K); 150mm PIR Insulation for vaulted ceilings (25% area with U-value = 0.177 W/m2K). Airtightness measures included.
Floor insulation Suspended timber floor (with Airtightness measures) – 70mm PIR Insulation between joists (78% area with U-value = 0.219 W/m2K); Solid concrete floor – 120mm PIR Insulation (22% area with U-value = 0.146 W/m2K)
Airtightness improvement In order to achieve this I fitted good quality double-glazed period timber windows (with trickle vents) that feature double-seals and ensured all penetrations, gaps and details were properly sealed to maximise airtightness. I also installed an inline extract fan, with high flow rate, to the bathrooms to ensure the option to provide boost ventilation (and minimise humidity) was available. The home is otherwise naturally ventilated.
Fitting a condensing boiler, with good controls (including percentage of TRVs) Remeha Avanta 28C condensing combination boiler (90% efficiency) installed with low temperature emitter system (oversized radiators) using a design flow temperature of 55°C. Remeha iSense control (Ecodesign Class VI) providing weather and load compensation. Only bedrooms and utility room feature TRVs to maximise boiler efficiency (minimise cycling).
Main method of heating hot water Remeha Avanta 28C condensing combination boiler
Low energy lighting Yes, CFLs and LEDs throughout, except Kitchen
Water saving devices and installations Flow regulators installed on all taps, toilets and showers (except bath) – this also improves service quality
Measures installed in detail:

  • Internal wall insulation
  • Floor insulation
  • Roof insulation
  • Double-glazed timber windows and doors
  • Air-tightness improvements
  • Condensing boiler
  • Compensating boiler control
  • Low temperature heating system
Benefits of work carried out:

The home is cheap to operate and very comfortable throughout the year. The Indoor Air Quality is also very good and I always recommend including provision for effective boost/purge ventilation to control humidity – many fans simply don’t work properly.
