Unit 4 – Create the Built Environment: Methods & Materials
›››› using energy-saving light bulbs
›››› insulating cavity walls and loft spaces.
Another way to reduce the amount of energy taken from the
national grid is through sustainable building design, such as use of:
›››› passive solar heat and light – the warming effect of the sun. The
location and alignment of a building, placement of windows and
careful selection of materials can make the best use of passive
heat thus reducing energy consumption
›››› local alternative energy systems, including solar panels and wind
turbines
›››› better insulation features
›››› high-quality distribution systems.

Sustainable construction and site practice
There are several innovative techniques that the construction
industry can use to reduce the impact of construction processes
