Building regulations

The rules about how much Britain’s carbon emissions should be reduced by, and when, are changing all the time — and are becoming more demanding.

Buildings are responsible for about half the UK’s carbon emissions and so Building Regulations set out fundamental requirements which must, by law, be met when designing a project.

Building Regs Part L are designed to enhance sustainability, improve the use of low-carbon fuels, and reduce greenhouse gas emissions by at least 26% by 2020 relative to 1990 levels.

The current version of Building Regs Part L2A is the 2013 Edition which came into effect on 6th April 2014.

The regulations are not only about improving energy efficiency but also about understanding where energy goes in a building and taking steps to monitor and reduce this. To this end they encourage sustainable design & construction, include requirements to conserve and measure energy use in buildings, and advocate the adoption of green energy & control systems. For the first time, the 2013 version considers utilised energy (rather than just the installed load) and a new measure, LENI, measures the thing that really matters – the lighting energy used per square metre.

Delmatic systems comply fully with the regulations and address all the requirements – and more – including manual control of lighting, daylight-linking, presence detection, absence detection and automatic timed control, as well as energy metering and monitoring.
