Achieving a B1 BER
With a Pre-BER (Building Energy Rating) of F, and a post-BER rating of B1, this energy upgrade project included in the 2024 One Stop Shop Scheme is now a modern, energy-efficient, comfortable and healthy home.
This F-Rated home had a primary energy rating of 386.55kWh/m2/yr, and 96.28kg/CO2/m2/yr carbon dioxide emissions indicator.
The post works final results came in at 87.06kWh/m2/yr for primary energy use and 14.49kg/CO2/m2/yr for the carbon dioxide emissions indicator, resulting in an overall energy rating of B1.
Upgrading Ireland’s Housing Stock
Located in Co. Donegal this 1940s home was included in the 2024 One Stop Shop Scheme, part-funded by SEAI, to undergo whole home energy-efficiency upgrade works. The grant provided by SEAI helped fund the energy efficiency upgrades including wall and attic insulation, heat pump, mechanical heat recovery ventilation, and new triple glazed windows & doors. KORE Retrofit Ltd. provided project management services, design solutions, technical expertise, quality control services and full grant administration.
A Complete Home Energy Upgrade
Wall Insulation
100mm of KORE external wall insulation was installed on the existing building using the SolTherm external wall insulation system. Best practice and high-quality workmanship ensured that repeating and non-repeating thermal bridges were eliminated or kept to a minimum.
Attic Insulation
300mm of mineral wool was installed in the attic, between the joists, providing comfort and efficiency in the attic space.
Heating System
KORE installed a 5kW Thermia air-to-water heat pump, providing heating via a renewable source, eliminating the use of fossil fuels, while decreasing carbon emissions. New radiators and heating controls were installed throughout the home.
Ventilation
Vent Axia mechanical heat recovery ventilation was installed to provide superior indoor air quality that adjusts the rate of air exchange based on needs, including advanced settings for wet rooms such as the kitchen and bathroom.
Windows and Doors
Future proof uPvc windows were installed in the home, with ultratech front door and one ultratech composite door at the back.
