2) Environmental savings

What green services can do for your Charity or Social Enterprise

We can assist social enterprises , charities and voluntary sector organisations fulfil their legal & moral obligations whilst saving money by providing a range of outsourced or support for `green services`. This includes devising a `Green Strategy ` by carrying out an audit of current practices and devising attainable targets which transforms the way the organisation inter-acts with the environment minimising the impact. We may be also able to achieve some funding for you to help allay the cost. Please also see our section on the Passivhouse.

One major component of our approach focuses upon the reduction of energy consumption and CO2 emissions. The changing climate, legislative, funders and regulators requirement’s brings renewable energy sourcing and insulation levels within buildings into the cost equation. It highlights the fact that `green` is a necessity not a luxury. We help the environment, achieve substantial savings and generate an income through a renewable energy strategy.
The benefits of renewable energy is that (subject to free site survey) it never runs out; there is more than one choice and combining 2 or more sources can provide even greater savings. The benefits of higher insulation is that (subject to free site survey) we can find the cost effective options for all types of offices and building detailing  the benefits it will bring. Depending on the services you provide we can arrange suitable times for survey/installation etc. Below is further information on energy alternatives we can provide subject to suitability.

Ground Source Heat Pumps

This uses the natural heat stored in the earth so that for every 1 Kilowatt of electricity used to power the pumps generates 4 KW for consumption. It requires a separate cylinder and can be used with solar water heating. It is very suitable for new developments with available land.

Air to Air Heat Pumps

This can provide both heating and cooling with air purification technology distributed directly into the building airspace. It converts latent energy in the air (even on cold days) absorbing heat via a refrigerant solution into hot air. It is suitable for a wide range of buildings (flats, offices, churches, halls etc) and operated using a remote control. It has a co-efficient of performance (COP) of appox 4.6.

Air Source Heat Pumps

This absorbs heat from outside even when the temperature is as low as minus 15C distributing via radiators, under-floor, or warm air convection alongside hot water. The co-efficient of performance (COP) is typically in excess of 3.0. ASHP`s can provide an income via the govt Renewable Heat Incentives (subject to changing tariffs) & need little maintenance (fit & forget).

Solar PV

This converts solar energy to DC power via panels on the roof or walls. Any surplus electricity can be sold back to the national grid. The average domestic system of 3.5 to 4 KW cost £5K (incl VAT at 5%) with larger systems more cost effective. The smaller size can generate 3000 KW hours of electricity per year typical household saving 1 tonne of CO2. If eligible for Feed in Tariff generates savings of circa £600 per year.

Solar thermal

This produces hot water but requires back up for nights and cooler days. It can produce 50-70% of average requirements over the year with more in summer and less in winter. Solar thermal part of RHI payment scheme from April 2014 based on 19.2 p/KWh.


These latest panels unlike solar thermal work in all weather 24 hours a day all year producing 100% hot water for a typical 4 bed house, take little to install, weigh only 8KG,  heat a temperature of 55C  and are an easy replacement for traditional boilers. Thermodynamics have a COP of 4.0 but rise to a high of 7.0 on larger systems with up to 80% savings on current hot water bills.

Green Benefits

-Whilst energy supplier will continue to raise prices the sun/air/earth as fuel sources are free.
-All increase property values
-No planning permission required (unless in conservation area or listed building)-Systems are durable with lifespan 30-40 years.
– The co-efficient of Performance (COP) measures efficiency via the ratio of input energy to output energy. The COP of electrical heating is 1.0 and gas heating is between 0.6 and 0.9 compared to thermodynamics of 7.0, Air to Air Heat Pumps of 4.6 and Air Source Heat Pumps of 3.0 demonstrating considerable gains on an annual basis.

So consider what your charity needs to do and talk to us. Please also see our section on the Passivhouse (or Passivhause). 

It costs nothing to talk to us. Our conversations are in the strictest confidence and covered by both our confidentiality agreement & Terms of Business as displayed on this website.
