Reducing energy costs for schools and colleges in Sussex

Schools and colleges across Sussex can free up budget and demonstrate leadership by driving down their use of fossil fuels

As a result of years of austerity budgets, schools and colleges in Brighton and Hove are used to juggling scarce funds.

Spending on educational resources such as books and ICT is an obvious priority, but providing adequate lighting, heating or cooling is also important in creating an optimum learning environment.

Installing appropriate energy saving or energy generating technologies will minimise the amount of money that schools have to spend on heat and power and achieve a significant reduction in monthly outgoings, leaving more money available to spend on teaching resources and staff.

A well thought out energy policy also delivers a clear signal to students and the wider community that your school or college is demonstrating action and leadership in the fight against climate change.

Why energy efficiency improvements make for a successful school or college

Research by the Institute of School Business Leadership1 indicates that energy costs are often the second highest expenditure in schools after teachers and staff.

Whilst energy demand and associated costs will vary from site to site, what is true for all school facilities is that energy costs can be managed and minimised by implementing an effective long-term energy strategy.

By introducing energy efficiency and renewable energy initiatives in your school or college, you will not only secure significant cost savings and create and improved learning environment, you will also be providing a powerful demonstration of sustainability in action. You are showing a willingness to take steps to reduce the dangers of climate change and are encouraging responsible behaviour from students and parents beyond the school gates.

Government bodies are beginning to recognise the important role that educational establishments have to play in our move to a zero carbon future. In its election manifesto, the current government pledged £2.9 billion over the next five years (yet to be confirmed) towards improving energy efficiency in schools and hospitals to boost momentum in energy efficiency sector supply chains.

In Brighton and Hove, schools and colleges are based in a wide variety of buildings. Some are relatively new, some are very old, and all will present unique challenges when it comes to designing an energy performance improvement strategy.

Identifying the most effective ways to reduce energy costs for your school or college

To identify opportunities for improving the energy performance of your school it is vital to gain a thorough understanding of energy demand and consumption patterns.

For this reason, a bespoke BHESCo energy survey should be the first phase of any planned building improvements, underpinning every other stage of your future energy strategy.

The most appropriate solution for improving energy efficiency will differ from school to school depending on the physical characteristics of the building and the particular ways in which it is used day to day.

Our bespoke energy survey will provide a thorough and detailed examination of every aspect involved with heating and powering your building.

Our Energy Saving Team will conduct an on-site survey to capture all relevant data, using FLIR thermal imaging software where neccessary. We will analyse your energy bill data to gain an understanding of your energy usage and to identify where performance can be improved.

We will produce a survey report detailing where heat and electricity are being wasted and recommending the most cost-effective ways to take remedial action.

Our report will look at a variety of potential solutions for your buildings, comparing the costs and benefits of different types of technologies. This includes a breakdown of the anticipated reduction in energy demand that we would expect from installing specific measures and the corresponding financial savings on future energy bills.

This allows you to make an informed decision about which technologies will deliver the best outcomes for your school or college and which offer the best value for money and quickest payback timeframes.

What typical upgrades can be made to improve the energy performance of schools and colleges?

The optimal design for improving the energy performance of your educational facility will incorporate a range of energy saving and energy generating technologies that work in synergy to deliver maximum efficiency.

Schools and colleges are often ideal candidates for generating solar heat and power. Their buildings are used throughout the day when solar power is at its peak, and they often have large roofs that provide ample space for large solar arrays. Depending on individual circumstances, other appropriate energy generating systems might include the installation of air source or ground source heat pumps.

On top of generating your own energy, there are many ways to reduce the volume of heat and power that your school or college uses. One of the most effective ways is to instantly reduce inefficiency and heat loss is by ensuring that roofing, walls, windows and doors are adequately insulated and draught proofed.

Does your heating system have the latest efficiency controls such as smart thermostats and data-driven heat demand management? Have you switched to LED lighting and installed movement sensors or power down plugs?

These are just some of the questions that school facilities managers must address when reviewing their energy strategy. Other considerations can include:

For schools that have solar panels installed the addition of battery storage technology enables owners to store electricity for use at a later time of their convenience.

Battery storage can also enable users to take advantage of ‘Time Of Use’ Tariffs, whereby a battery can be charged during times when energy prices are low and discharged at when prices are high.

Alternatively, they may choose to sell any surplus electricity back to the electricity grid at times of high demand.

Switching from traditional incandescent or halogen lighting to energy efficient ‘Light Emitting Diodes’ (LEDs) can reduce electricity consumption for lighting by up to 90%.

Adding motion sensors for lesser used rooms or corridors can further help to drive down energy bills.

Chances are that your heating consumption makes up the lion’s share of your monthly energy bill.

Generating your heat more efficiently can greatly reduce your bills and dramatically improve comfort in your property. This could involve installing radiant panel heating or underfloor heating.

Depending on the the type of building in question and the amount of neighbouring land available you may be able to start generating your own renewable heat using and air source or a ground source heat pump.

The cost of heating in the UK can be very expensive.

If you are losing heat through draughty windows and doors then your property will not only be uncomfortably cold but you will be wasting huge amounts of money as well.

Improving your windows and doors will make your property feel much warmer in the winter and much cooler in the summer.

Furthermore, as well as helping you cut down on energy bills, new windows and doors will reduce levels of noise pollution from outside.

Any floor that is above an unheated space (like a garage or a basement) can easily lose a great deal of heat to the colder area beneath.

In some properties heat can be lost throught the ground floor as well, so it is important that floors are properly insulated wherever possible.

The type of floor in your property (concrete or suspended timber) will determine which solution is most appropriate.

Hot air rises, which means that up to a quarter of heat loss in can occur if your roof is not properly insulated.

Fortunately, topping up your loft insulation is one of the cheapest and easiest ways to make a big difference to the energy efficiency of your property.

Increasing the depth of your loft insulation to the recommended minimum of 270mm will immediately improve comfort and wellbeing while helping you to dramatically reduce energy bills.

The majority of heat loss  occurs through the walls – in some cases heat loss though uninsulated walls can account for up to half of all heat loss in a property.

There are a variety of solutions for improving the energy efficiency of your walls which can depend on the age and the type of the property.

Possible solutions could include Cavity Wall Insulation, External Wall Insulation, or Internal Wall Insulation.

If neccessary our energy assessment can include a boroscope survey to identify the current state of the walls and what insulation there may or may not be already.

In many instances there is no need for lights to be left on continually. Adding motion sensors to turn lights on automatically whenever an employee is in the vicinity will cut down on waste and can achieve savings of up to 30%.

It is also advisable to install remote heating and lighting controls, enabling specific heat and light levels to be set for different zones of the building and in relation to time and seasonal variations.

Integrating remote monitoring and controls will enable facilities managers to continually gather and analyse data about a building’s energy use, adjusting heat and lighting settings in reaction to the information available, and creating a business case for the adoption of new measures where necessary.

How schools can show leadership on the climate emergency

Today’s young generation demand urgent action and leadership on the climate emergency.

As demonstrated by the recent school climate strikes and the popularity of climate action groups such as Extinction Rebellion, many young people are deeply concerned about the threat of climate change and feel let down by many of their leaders and the older generation.  

When covering environmental aspects of the school curriculum, what better way of bringing the climate emergency to life than through tangible examples of energy efficiency and renewable energy generation in your own school or college?

The importance of buy-in from faculty and students

In order to gain maximum benefit from any physical energy efficiency improvements that are made to your school or college premises, it’s vital that you have the support and co-operation of your colleagues and students.

Educating colleagues and students on effective energy management and efficient behaviours will help to embed sustainability practice into the school or college. When colleagues and students have a good understanding of the financial and environmental benefits of sustainable behaviour, they will be better placed and more emotionally invested in supporting efforts to reduce energy consumption.

As well as reducing costs, encouraging colleagues and students to reduce energy consumption within the organisation demonstrates environmental responsibility and shows leadership within the wider community.
