Green Energy

As Project Managers we are at the forefront of considering alternative sources of energy to light, power, heat, cool and ventilate the building we deliver to our customers.

Depending upon the specific location of each site we will consider: -

Solar Energy

• Solar Water Heating
• Flat Plate Collectors
• Photo Voltaic Cells
• Passive Solar Design

Wind Energy

• Vertical Axis Wind Turbines

Small Scale Hydro Power

Biomass Energy

• Wood (chip, pellets)
• Willow & Poplar
  (grown on short rotation Coppice System)
• Energy Crops (Miscanthas, Switch Grass)
• Agricultural Waste - Straw

Geothermal

• Ground Source Heat Pumps

When the sun shines on the ground its heat energy is adsorbed. Ground source heat pumps extract this energy, to use for space heating. So strictly speaking, the energy source that is used for ground source heat pumps is the sun and not the heat from the earth.

In the UK, the constant ground source heat temperature is around 12°C and can be utilised to heat and cool buildings.  Pipe is buried underground in a trench or in a vertical well and water is pumped through it and heated by the underground energy.  A heat pump can extract the ground’s heat and transfer it into a building for space and water heating, or it can remove heat from a building and deposit it into the ground to cool the building during hot weather.

Heat pumps do need some power to operate.  However for 1 unit of energy they use they generate 4 units of power.  The energy generated by a ground source heat pump can be considered 100% renewable if the power to operate the pump comes from solar electric panels or a wind turbine for example.
