Mar 24, 2009 · The Wonderful Energy Excel Spreadsheet. A number of months ago there was a post with an Excel Spreadsheet for you to work out gas and electricity cost by meter readings. What a fantastic spreadsheet I have used it religiously every week since it was put on year so thank you to the creator.

- So Who Enforces this?
It’s a UK building regulation issued by the Secretary of State which lays down specific measures for the conservation of fuel and power. It is now a general aim to make our buildings as energy efficient as possible and therefore efficient electric lighting is required in most buildings. You will have to comply with this regulation when your buildin...
Building regulations are legal requirements. You have a responsibility for ensuring compliance with building regulations and could be served with an enforcement notice, prosecuted and fined in cases of non-compliance.
Dwellings
In the previous Domestic building compliance guide, compliance was achieved with 75%, so 3 in every 4 of the fixed internal light fittings needed to have a minimum of 45 lamp lumens per watt. They also need to an output greater than 400 lamp lumens to count. This is now no longer the case and has been superseded with the below; 6.57 Any fixed lighting should achieve lighting levels appropriate to the activity in the space and spaces should not be over-illuminated. NOTE: In many cases, it is l...
Buildings other than dwellings
In the non-domestic building compliance guide again you can skip to Section 6 (page 52) for the lighting part. Importantly, for this section the regulation makes a clear definition between luminaire lumens and lamp lumens. Light fittings, often referred to as Luminaires, are not 100% efficient and a proportion of light is absorbed or blocked by the reflector, diffuser, or lamp shade. Luminaire lumens is the amount of light (lumens) produced by a product after you take into account these losse...
LENI (Lighting Energy Numeric Indicator) has also been included as an alternative to minimum luminaire lumens per circuit watt. So there are now two options to calculate energy use and show compliance. LENI is a change of philosophy, looking at energy use rather than installed load. It measures predicted energy used by a lighting system over the le...
The role of checking that building regulations are being complied with falls to Building Control Bodies (BCBs). There are two types – the Local Authority Building Control (LABC) or a private sector Approved Inspector Building Control (AIBC). Customers are free to choose which type of Building Control Body they use on a project. In addition a compet...
The collectors market for electric Aladdin lamps has virtually collapsed for the common lamps. The finial may be worth more than the lamp base and shade of many lamps. These electrics are utility lamps today – use and enjoy them as memories from the past.
