HADEN COURT ENERGY EFFICIENT ESTATE IMPROVEMENT

ABSTRACT Haden Court is a demonstration project within the Energy Efficiency Office's Energy Efficiency Demonstration Scheme looking at rehabilitation of traditional construction, low/medium-rise flats. It shows that a comprehensive package of energy measures, including both insulation and passive solar features can provide energy-efficient homes cost effectively when applied as part of a general rehab programme — as well as providing additional, non-energy benefits. An energy target of 25–30% below 1985 Building Regulations standards was achieved using available technology — which is still 10–20% below the revised 1990 Regulations. Stage I was completed in May 1990: the cost of the energy measures was £2430 per flat — out of a total of £34800 per flat. With a predicted saving of £110–220/flat per year this achieves a simple payback of 11–22 years.
