Retrofit Case Study- Better Energy Communities
The video below shows the works involved to upgrade this home from a G rating to an A3 rating.
Case Study – 1960’s Cottage
Project Description: A three bedroom bungalow with a high energy rating. The home was losing a-lot of unnecessary energy due to a lack of air tightness so the Sola team suggested a number of measures to improve the efficiency of the home;
Replacement of all windows and doors
Retrofits to improve air tightness
Installation of demand controlled ventilation
Replacement of the oil-fired boiler with an air source heat pump
These were the minimum number of upgrades suggested.
Pre Works– BER Rating: G
Post Works– BER Rating: A3
Works carried out included:
PVC Windows and Doors
100mm Platnium EPS External Insulation
Demand Control Ventilation
Air Source Heat Pump
Wood burning Stove
Sola also provided additional meters to keep track of the energy usage.
This retrofit has made this home far more efficient and healthier. Heating can be one of the homes biggest expense and effective insulation can reduce heat losses of up to 90%.
Not only has this retrofit provided savings but it also has provided a comfortable environment within the home.
The works completed resulted in the home improving its energy efficiency while decreasing the energy demand. Energy efficiency retrofits can reduce the operational costs, particularly in older buildings, as well as help to attract tenants and gain a market edge.
Renewable Heating – Heat pump
Advanced Ventilation (heat recovery or demand controlled ventilation)
Cavity wall, attic, flat roof and external wall insulation
