Energy efficiency in loft conversions

Loft conversions are important; they can provide new, energy efficient accommodation and can also improve the overall energy efficiency of the houses. Converting a loft into a living area provides more space but need not increase heat losses or fuel costs.The homeowner can quickly recover any additional costs for energy efficiency measures through reduced fuel bills. Payback periods are usually less than seven years, and fuel costs are reduced for the entire life of the building.

The three most important factors that contribute to energy efficiency are:

• the level of insulation and the air-tightness of the walls and roof;

• the choice of fuel and the efficiency of the heating system;

• the efficiency of lights and electrical appliances.
