Rosscarbery Housing Association, National Housing Retrofit Scheme Case Study
KORE case studies offer an inside look at how our retrofit solutions perform in real-world applications. This deep retrofit was part of the 2021 National Housing Retrofit Scheme, coordinated by KORE Retrofit and supported by the Sustainable Energy Authority of Ireland (SEAI).
Case Study Details
Project Name: Deep Retrofit of 11 homes in Rosscarbery, Co Cork
Products Used: KORE Fill Cavity Wall Insulation, 5KW Panasonic Heat Pump, Aereco Demand Control Ventilation System, uPvC Windows and Doors.
Project Coordinator: KORE Retrofit Ltd.
Sub Contractor: Waterford Insulation
KORE Project Manager: Leighanne Fay
“We built 11 homes in phase one of our development in 2005, and then in 2021 we decided to retrofit these homes with funding from SEAI to give extra comfort to our elderly residents. KORE Retrofit were the chosen contractors for us and we found them to be very professional and they gave us a project plan for the different stages of the project which we shared with residents to minimise disruption as they all remained in their homes during the works.
All our residents are delighted with their “new” warmer energy efficient homes. Thanks KORE Retrofit.”
Achieving B1
11 homes took part in a whole home energy upgrade under the National Housing Retrofit Scheme, with varying Pre-BER’s (Building Energy Rating) of E1-D1, and post-BER ratings of B1 and B2.
One home, for example, House A, starts with a pre-works BER of E1, a primary energy rating of 323.99kWh/m2/yr, and 63.71 kg/CO2/m2/yr carbon dioxide emissions indicator.
The post-works final results came in at 105.12 kWh/m2/yr for primary energy use and 20.67 kg/CO2/m2/yr for the carbon dioxide emissions indicator, resulting in an overall energy rating of B2.
Upgrading Ireland’s Housing Stock
Located in Rosscarbery, Co. Cork, these 1980's homes were included in the 2021 KORE National Housing Retrofit Scheme, part-funded by SEAI, to undergo energy efficient deep retrofit works. The grant provided by SEAI helped fund the energy efficiency upgrades including cavity wall insulation, attic insulation, air-to-water heat pump, heating controls, and demand control ventilation. KORE Retrofit Ltd. provided project management services, design solutions, technical expertise, quality control services and full grant administration.
Breaking down the details
Wall & Attic Insulation
The existing cavities were filled with KORE Fill Cavity Wall insulation, achieving a U-value of 0.32W/m2K. Existing attic insulation was topped up with mineral wool insulation of 400mm, achieving a U-value of 0.12W/m2K. Best practice and high-quality workmanship ensured that repeating and non-repeating thermal bridges were eliminated or kept to a minimum.
Heating System
KORE installed a 5kW Panasonic air-to-water heat pump system to provide all homes with reliable, trouble-free, renewable heating and hot water. The existing radiators were upgraded with new low-temperature radiators with full heating controls.
Ventilation
KORE installed an Aereco V4A Premium Demand Control Ventilation System, designed to ventilate the complete home, providing comfort and healthy indoor air quality.
Windows and Doors
KORE installed new composite doors on all 11 properties, as well as new uPVC windows, which provided a U-value of 0.94 W/m2K for the windows and a U-value of 1.1W/m2K for both external doors. LED lighting was utilised throughout the entirety of the house.
