SuperHome case study – Neil & Aileen Walker

A SuperHome is an energy efficient home that has implemented all the cost effective and sensible energy measures. These include insulation, air tightness and advanced ventilation. Heat and hot water is provided by renewable energy technologies such as solar photovoltaic panels and heat pumps.

Since the launch of the first pilot programme in 2015, we have retrofitted over 70 houses to a near A3 Building Energy Rating (BER). The average net investment by homeowners in 2017 was €33,000. As well as average financial savings of €1000 – €1500 per annum on oil, homeowners benefit from living in a comfortable, healthier house with better air quality.

Before Neil and Aileen Walker retrofitted their 1995-built timber frame house it had a C2 energy rating. “Not the worst but not great,” says Neil, an engineer who heads up the energy and environment section of the national business confederation, IBEC. Their 175sqm home is a two story four bedroom detached house on quite an exposed site in Ballyboughal, north Dublin.

“For a long time we had struggled to heat it effectively. The kitchen diner was never warm and various attempts over the years, such as extra insulation in the attic and wood stoves rather than open fires, had not made much of a difference,” says Neil.
