How did a large comprehensive school achieve a dramatic reduction in gas consumption by Smart Metering?
A large comprehensive school achieves a 42% reduction in gas consumption simply by implementing smart metering. The school with 1,600 pupils and a large leisure centre has seen gas costs rise inexorably over the last few years. New boilers and efficient controls were tempting choices, but the first move is to use the data from the Smart Meter to analyse current consumption patterns, identify areas of waste and consider possible solutions. Overview: Prior to the start of the program the school had an approximate annual gas consumption of 1.7 million kWh. This was projected to reach 2.2 million kWh within a year. The current cost was £39,000 per annum and would rise to £50,000 if nothing was done. To compound this, gas prices are forecast to increase over the coming years, putting even more pressure on budgets.

British Library saves energy and money:

£30,000 reduction with SavenergyOnline
Although the British Library has reduced energy consumption by 15% over the last four years, fuel prices - and therefore energy costs - continue to climb. Like all organisations, the Library has had to improve its ability to reduce wastage to try and lessen the financial impact.
The British Library has 16 half hourly electricity meters located in buildings across London and Yorkshire. In order to maximise a reduction in waste and costs usage data was needed fast and accurately without waiting for the monthly energy invoice, in order to see where further savings could be made.
Environmental Manager, Gerry Goldner, explained: “Originally I had to rely on the figures sent to me by the electricity supplier, which were a month out of date, and do all the number crunching myself. What I needed was speedy and accurate data and software that would run the analysis for me.”
The information that SavenergyOnline provides has shown that, on the four smaller sites, there is a definite pattern of usage. As a result, the Library decided to opt for a seasonal time of day contract profile, where the summer time costs are considerably lower than standard 2 rate profiles, but where the charges between 4pm-7pm in the winter rise sharply. At the flagship St
Pancras building, winter time demands can be managed lower, giving even more reduction in costs. The additional savings are at least £10,000 per year. Gerry concluded, “SavenergyOnline has proved to be a highly cost-effective, energy-saving service. We are in a win-win situation.”

Bath University, 3 West North – optical fibre laboratory

A combination of technology, information and people make big savings and so, thanks to the efforts of Harry, Alan and the team in Estates has saved
  • 380,000 kWh every year
  • £35,000 every year
  • 160 tonnes CO2 every year
3 West North (3WN) is one of the newest buildings on the campus, built in 2005 to house a number of research laboratories as part of the Department of Physics. It includes drawing towers for making photonic crystal fibres, a 200-seater lecture theatre and two general teaching classrooms for 100 and 30 people, as well as various labs with equipment including lasers, lathes and furnaces. This vital research, however, is energy intensive, and the building has an annual electricity bill of £70,000.
Within the Department of Estates, significant investment has been made in improving the energy monitoring of buildings such as this, and through the Our Big Energy Challenge project, a departmental energy champion has been trained and now acts as a point of contact for the Energy & Environment team.
This champion, technician Harry Bone, together with Alan George, the Technical Manager for the department, helped organise the key people to get together and examine the energy information for the building. An action plan was put together and certain key changes to the operating regime were made, without risking the integrity of the research conditions.
The very positive results of this exercise can be seen in the graphs below showing the weekly electricity usage pattern before, during and after the changes were made.
