Achieving A3
With a Pre-BER (Building Energy Rating) of C3, and a post-BER rating of A3, this energy upgrade project included in the 2021 National Housing Retrofit Scheme is now a modern, energy-efficient, comfortable and healthy home.
This C3-Rated home had a primary energy rating of 223.8kWh/m2/yr, and 56.46 kg/CO2/m2/yr carbon dioxide emissions indicator.
The post works final results came in at 73.55 kWh/m2/yr for primary energy use and 14.46 kg/CO2/m2/yr for the carbon dioxide emissions indicator, resulting in an overall energy rating of A3.
Upgrading Ireland’s Housing Stock
Located in Trim, Co Meath this 1970's home was included in the 2021 National Housing Retrofit 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, air-to-water heat pump, and new windows and doors. KORE Retrofit Ltd. provided project management services, design solutions, technical expertise, quality control services and full grant administration.
Breaking down the details
Wall Insulation
100mm of KORE External EPS70 Silver insulation was used on the main house, achieving a U-value of 0.15W/m2K. Internal wall insulation boards were used on two walls adjacent to the garage, achieving a U-value of 0.20W/m2K. 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, for a total of 375mm in the attic achieving a U-value of 0.13W/m2K.
Heating System
KORE installed an 12kW NIBE air-to-water heat pump system to provide the home with reliable, trouble free, renewable heating and hot water. The existing radiators were upgraded with new low temperature radiators with temperature regulating valves.
Ventilation
Aereco demand control 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
KORE chose uPVC triple-glazed low energy windows with a U-value of 1.1W/m2K and two composite doors, front and back. The windows were set out into the insulation layer which minimised thermal bridging, as well as airtightness tape used on all windows and doors.
