Global problem, local solutions
Airedale Mechanical and Electrical Ltd is committed to working with all stakeholders to create and sustain enhanced environmental performance on all projects. We constantly keep our skills and knowledge at the cutting edge of the latest efficiency-driving technologies.
Our renewable energy policy is to surpass Planning Policy Statement 22, part L2A and part L2B. We explore all options for electricity & heat generation, cooling and combined heat and power generation. We are unbiased in our selection of technologies - whichever is most fit for purpose, taking into account natural resources, aesthetics and access.
Ground source heat pump
- The Earth's natural heat remains reasonably constant
- Like a huge rechargeable battery with sun providing energy
- Can be used to heat liquid for space heating circulation
- Can achieve a coefficiency of 3kw electrical power in - 4kw of heat out and thus gaining 25% of heat
Reduced noise helical wind turbines
- Can be an effective source of renewable power
- Site winds of 12.5m/s can generate approximately 1.5kw of electricity
- Many systems available to store power or offset bills
- Usually a planning submission required for the installation
Photovoltaic cells
- Generate direct electrical power when exposed to light
- Can achieve 7 - 15% efficiency under lab conditions
- Due to the size of panels vs power produced, they seldom feature in more than school education facilities
- 5m2 panel is expected to produce approximately 500W of useful electricity
Solar hot water panels
- Water heated by approx 16oC, saving energy before being 'topped up'
- Ideal for smaller buildings
- Become difficult in larger schemes where larger roof area is needed
- Payback in an office context is of the order of 40 years
- Buildings with high hot water use may benefit more
