Alternate Energy Systems

Combined Heat and Power

Combined Heat and Power (CHP) is an energy efficient form of plant which uses fuel for heating and uses the excess heat to generate additional electricity. This creates efficiencies of some 30% over traditional heating approaches. It is commonly used in larger buildings, although micro CHP can be used in homes

Other Energy Efficient Plant and Equipment

Artificial lighting, cooling or heating may be unavoidable in certain situations. Where they must be used there are often low energy alternatives which may be sourced and used.

Energy Efficient Management Systems

There are a number of ways of managing energy. Where the user has control or there is an automation of systems through the use of motion sensors or zoned heating and lighting, for example. The management of heating and lighting at this level can make significant contributions to energy efficiency as energy is only used when it is needed.

Renewable Energy

Renewable energy is generated from non-fossil based sources which are easily replaceable or freely available. This includes energy generated from the wind, sun or heat sources in the ground. It can also include energy generated from waste products. The energy may be used within the building itself or sold back to the National Grid.

Photo Voltaic Cells

Photovoltaic cells (PVCs) or solar panels have been in use for some time. They rely in the energy from the sun to generate electricity for use within the building and for potential sale back to the National Grid.

Passive Solar Heating

In addition to passive solar design, heating energy can be replaced by using solar water heating. This does not create energy to be released as electricity, but rather used to heat water and thereby replace traditional fossil approaches.

Passive solar is growing in popularity for domestic water heating. The ease of installation, maintenance and the lack of a need for it to be connected to the grid mean that it is already a viable option in terms of using solar energy to reduce traditional energy consumption.

Wind Turbines

Wind Turbines are a common, explicit way to be seen to be generating renewable energy. They take the form of windmills which use the power of the wind to turn the blades and generate electrical energy. The energy may then be used within the building or for resale to the national grid.

Ground Source Heating

Ground source heating uses the heat held within the ground to heat a building, usually through under floor heating. There are a number of different approaches, but the common approach is for pipes, containing a heat carrying medium, to be placed in the ground and the medium to be pumped from the ground where it is heated into the house heating system. This approach is becoming increasingly common.

Biomass Boilers and CHP

Biomass is fuel that is created from biological waste materials, commonly wood which are processed into pellets. Biomass boilers work using fuel from renewable sources, such as wood pellets. These work in the same way as traditional gas boilers, although there is an increasing use of biomass approaches being combined with CHP.

Energy Generated from Waste

This approach works in a similar way to biomass. Energy is generated using treated waste to create material which can be used in boilers to generate electricity.
