The demand to optimise energy systems producing either heat or electricity or other fuel is high. The following systems are efficient (>80%) and enhance the performance of other renewable systems.
Ground and Water based Heat Pumps We specify and install these systems when either landscaping and or water feature are present in a project because they can greatly increase the heat available especially if there is a surplus of electricity. 1kw of electricity can be converted into around 4kW of heat just by burying a matrix of pipes in the ground or a water source.The larger projects abstract ground water for cooling via Bore Holes these techniques save large amounts of energy used in the Air Conditioning of buildings.
Ground,Air & Water based Cooling Systems By integrating simple methods of cooling within buildings significant performance enhancements can be realised ie drawing intake air through below ground ducts (earth tubes) and/or using passive stack effects to drive air to air heat recovery maximising natural ventilation. We factor in life cycle and energy costs into our selection proposals to give you the optimum options. We are fully independant from all manufacturers and can propose alternative solutions.
Power Factor Correction/Active Harmonics/step down transformers/ load balancing The devices simply and effectively reduce the losses from all uses of electricity by improving lag or lead angles, balancing and eliminating voltage and current distortions or simply optimising the voltage to equipment requirements (UK 242V to EU 230V). Another simple way of reducing energy consumption is by analysing the dynamic phase balance of a load or whole building. This usually results in +-5% imbalance and lower peak demand loads. Typical reductions would be around 10% per annum saving energy and cost.
Timers / Meters & Controls The installation of simple timers / meters and reduction of temperature set points is one of the most effective ways of matching demand whilst at the same time saving money and energy. Seasonal control should be distributed and zoned to match occupancy / solar gain (heat and light) and heat loss. The reaction time of the buildings thermal mass should also be catered for. Other controls are also very effective (multi service metering and energy displays and increasingly internet / telephone enabled control devices are being installed.
The Site resources We advise including a site energy resource study as part of any projects. This can identify whether there are any renewable/sustainable applications for energy production and storage on site which can be integrated to form a resilient system. The occupancy patterns and waste streams and even the car park of a building are also energy resources.
