What is the main focus of the Code for Sustainable Homes?

• A. Setting standards for the environmental performance of new homes.
• B. Improving energy efficiency in existing buildings.
• C. Reducing construction costs through faster methods.
• D. Establishing safety regulations for site workers.

Answer: (B)

The Code for Sustainable Homes concentrates on setting standards for the environmental performance of new homes. It provides a framework to rate and improve how sustainable a new dwelling is, covering aspects like energy and carbon efficiency, water use, materials, waste, pollution, health and well-being, and management. It applies to new-build properties, not existing buildings, and its aim is broader sustainability rather than cutting costs through faster construction or establishing site safety rules.
