How to quantify the value of energy saving improvements

A question we get asked a lot is whether energy saving improvements add value to your property. For many of our clients, a positive answer makes the capital expenditure easier to bear as you know that you get the value back on a sale. Traditionally, energy and energy efficiency measur…

Reader tip of the month - turn it off!

We talk about technology a lot on the website, but technology by itself is not enough - it's the user that makes the most difference. It's no good having the most efficient boiler, if you turn the thermostat up high, and then open the windows when it gets too hot.  User-behaviour was the the…

How to send a simple signal that energy efficiency is important

We can bang on about the importance of energy effiiciency as much and as loudly as we want, but maybe there are more subtle ways of stating its importance and raising it up people's consciousness. On my recent holiday in France I saw two examples of simple, yet really effective awareness (and consci…

How to choose the best low energy lighting

Traditionally we've measured the strength of our lightbulbs in watts. A 40 watt incandescent light bulb was dim, a 100 watt one was bright. However, that measure was misleading. Watts are a measure of power consumption, not of light. A 100 watt incandescent bulb needed 100 watts of electricity to…
