Energy Efficiency News & CampaignsSchools Energy at Easter March 2013Easter comes towards the end of the heating cycle; however having just seen the weather forecast it may be as cold as Christmas. Good management of your schools energy use during Easter will deliver savings and help you establish your baseline. Remember the clocks move forward one hour on Easter day so make sure your energy controls reflect that change Heating Actions To drive down your heating costs during Easter the following actions could help:
Warning: Monitoring your energy use is the best way to control your consumption and save money. To check your current gas consumption details visit:: username – SCHOOL(no)*@HERTSCC.GOV.UK PASSWORD – School(no)* There are standard actions which can be employed to reduce electrical energy use during Easter.
After Easter there will no longer be dedicated staff to help schools reduce their energy consumption. Please visit the GRID Energy Management Pages for more ideas and help with your schools energy management. Save £30 for every 1000kWh gas your school does not use and £80 for every 1000 kWh electricity over the holiday. Most primary schools use between 1000 -3000 kWh of gas on a normal school-day and between 200-500 kWh of electricity
Half Terms Here - Another Chance for Energy Savings Feb 2013Over 200 schools managed reduce their energy consumption over the Christmas and New Year Holidays. Now another opportunity is here with half term fast approaching. How low can you go at during half term? Below is a list of actions that should help your school reduce its energy consumption and lower its costs. Heating ActionsThe following actions will help drive down your heating costs during half term:
Warning: To check your current gas consumption details visit: username – SCHOOL(no)*@HERTSCC.GOV.UK password – School(no)* Electricity ActionsThere are also standard actions to reduce electrical energy consumption:
Save £30 for every 1000kWh of gas your school does not use and £80 for every 1000 kWh of electricity.
Reduce Electricity Consumption - Free Lighting Surveys Available Jan 2013Analysis of electricity consumption across the school estate shows that many schools could benefit from an upgrade to their lighting system. HCC has the means and the money to make this happen. Lighting in schools probably accounts for up to 50% of the electrical energy used in a normal school-day. If your electricity consumption is three times or more on a school day compared to that consumed at a weekend or holiday, the opportunity exists to reduce your total electricity consumption by up to 25%. At the very least you can have a full lighting survey completed free of charge to identify the potential for savings. Currently HCC has an interest free loan fund, The Salix Fund, which will pay for the upgrade to be installed without any capital requirement from the school. The first loan repayment will not be due until March 2014. The deadline for forms to be returned is by March 31 2013. The normal return on investment is circa three years. Loans will only be awarded if the efficiencies within the proposal meet the criteria of the fund which are there to protect schools. The upgrade is a simple intervention that allows the most efficient fluorescent lamps to be installed into existing fittings. It is non intrusive and can be completed at times to suit the school. Typically an upgrade at a primary school takes 7-8 hours, which can be done at a time to suit the school including evenings. The upgrade comes with a five year warranty that includes replacement tubes and an annual service visit.
Christmas Energy Consumption Jan 2013Prior to Christmas schools were informed of actions they could take to reduce their costs associated with heating, and to aim to see how low they could go. Preliminary analysis of schools within the Hertfordshire estate shows that over 220 have made significant savings to their heating costs by ensuring their management system was set up for Christmas week. These 220 schools lowered their normal gas consumption significantly by ensuring they had programmed the holiday period correctly into their controller. Typically the average savings were several thousand kWh leading to cost savings in excess of £100. Modern electronic controllers can be installed for circa £3000 and have a return on investment of under 3 years. Salix funding is for community schools for this upgrade. The analysis also highlighted that there are many schools that are in full control of their heating, with weekly profiles that show controllers are set up not to deliver heat at weekends.; however many of these schools showed normal energy consumption on Christmas Day. If your school was one of those with normal consumption for Christmas Day then another opportunity is fast approaching to save heat energy with the February half term on the horizon. If you have AMR or optimal fitted you should be in the position to monitor energy use on a regular basis and identify any anomalies. Full instructions on the sign in procedure and what to look for are on the live energy monitoring tab.
Schools Energy Savings over Christmas Dec 2012Christmas falls after the main heating cycle has started in schools. It offers a major opportunity for schools to adopt good habits and to establish their winter baseline energy use for both electrical and heat energy. Below are standard actions which can be employed to reduce energy consumption over the Christmas break. Heating ActionsTo drive down your heating costs over the Christmas break the following actions could help:
Warning: To check your current gas consumption details visit: username – SCHOOL(no)*@HERTSCC.GOV.UK PASSWORD – School(no)* Electricity Savings
Find out what your energy baseline is this Christmas. Save £30 for every 1000kWh of gas and £80 for every 1000 kWh electricity your school does not use over the holiday. Most primary schools use between 1000 -3000 kWh of gas on a normal school-day and between 200-500 kWh of electricity. Senior schools use between 2000 - 10000kWh of gas on a normal school day and between 1000-3000kWh of electricity. The Grid energy management pages are regularly updated to help your school reduce its energy costs.

Save Money: Manage Your Heating Oct 2012Now that Autumn is truly upon us schools’ energy use will rise significantly as heating is switched on. Good management of your schools heating systems can save money and lower its carbon footprint. If your heating is on for a day when it is not needed you could save anything from £30 upwards. Regular interrogation of automatic meter readers enables anomalies to be identified, rectified and therefore leads to a reduction in energy consumption and costs. Monitoring will show if your automatic sensors are facilitating good heat management or simply wasting energy. Electronic controllers allow you to manage heating so that it corresponds with the school day. This means your heating can make sure the desired temperature is reached at the start of school, with another burst mid morning and a third after lunch to maintain comfortable temperatures throughout the day. Instead of one continuous heating period which often leads to heat being wasted at break and lunch times. See the potential savings available by looking at the case studies on the Grid. Brooklands School example shows what could happen by improved heating management at weekends:
or how minor changes to daily temperature and timing controls can lead to major savings over a school year. For more information and help contact your schools energy advisers:
