A few steps followed by many construction companies in UK and worldwide are;

Improving occupant comfort in buildings
Due to the importance of social aspects of sustainable development emphasis is placed on occupant comfort.
Reducing the impact of the construction process
There are a number of environmental and social impacts in the construction process including noise, dust, traffic, waste and health and safety hazards. Thus to minimize them the construction
