urgent need to transform our building stock to a better energy performance level, e.g. by increasing thermal insulation, installing better energy performing windows and improving energy efficiency of heating, cooling and ventilation systems.
At the same time, improving the energy performance of buildings and reducing the carbon footprint should not result in a negative impact on health, wellbeing and comfort of building occupants. A successful design or redesign of a residential building should aim at the best health and comfort performance in addition to good energy performance and use of resources.
It is important to remember that dwellings are primarily meant to provide a safe and enjoyable living environment for their inhabitants. In that context, it is also important to consider that the primary purpose of Building Regulations is to provide for the health, safety and welfare of people in and around buildings.
The principles and guidelines in this document can be used to guide and improve the design of residential buildings of all types, including apartment buildings, and are applicable to both new and existing dwellings.
