Energy

Designing homes to conserve energy and use it efficiently, from sources that cause least environmental harm.

Lighting design

For maximum energy efficiency, homes should be designed to make the most of natural daylight.

Lighting accounts for 11% of energy used in an average New Zealand home, and that percentage is projected to increase in coming years.

For maximum energy efficiency, homes should be designed to make the most of natural light during daylight hours.  See daylighting for details.

However, artificial lighting is necessary for times when natural lighting is not available/adequate and for specific tasks. Artificial lighting especially using LED fixtures can be designed to provide appropriate lighting levels while using energy efficiently.
