With higher education institutions in England making a commitment to a collective 38 percent emissions reduction goal between 2005 and 2020, coordinated by HEFCE (Higher Education Funding Council for England) saving energy is high on the agenda for all Universities. Over 40% of a typical university’s energy spend is on Heating Ventilation
and Air Conditioning and generally up to 25% of this is wasted energy. A major opportunity in achieving these carbon saving targets should be explored by University estates departments as the savings can be significant for minimal cost.
Annual energy costs for the Further and Higher Education (FHE) sector are around £400 million, resulting in CO2 emissions of around 3 million tonnes per year. It is, however, possible to reduce these emissions by around 25%.
Along with this come big financial savings too. Energy is one of the major costs to a University and can vary from £10 to £30 per annum, for each square meter of floor space (in the UK). The opportunity to optimise HVAC through BeMS exists in most Universities leading to a short payback period. This is done through optimising the performance of systems, assets and in particular the BeMS (Building energy Management System) that control many of the assets leading to considerable savings in terms of energy consumption, asset life and maintenance costs.
For every additional hour of occupation each day, the HVAC consumption can increase by as much as 10%. Incorrectly set time schedules, setpoints and optimiser can be a large contributor to this additional usage. Maintaining optimum internal environments for staff and students will improve comfort, which in turn will help boost attentiveness and morale, alongside minimising energy consumption and carbon emissions.
Reducing the heating temperature by 1°C can reduce energy consumption by as much as 8%
Regardless of whether your facility has previously undertaken extensive energy saving initiatives and you are at an advanced stage of your energy efficiency strategy or if this is the first step, we are confident savings can be made.
We will review the BeMS operation including: time schedules, setpoints and control strategies along with any energy consumption data that will help us identify where energy is wasted. We will also review the physical HVAC plant and identify areas of savings due to assets configured incorrectly, equipment in manual or areas that may require maintenance or repair. All of which will be formed into a strategy agreed with the client and documented to get the estate on track.
