Before thinking about eco technology, of which there are many different and excellent options and possibilities, we always advise our clients to consider passive, low cost design features first, such as Trombe walls; high mass construction with very high insulation to moderate temperature swings; natural ventilation and cooling; careful attention to airtightness; heat recovery ventilation systems; careful consideration of building orientation, glazing, shading, external shutters etc.; water management systems - rainwater harvesting, grey water recycling, heat recovery systems etc. 


Then we consider materials, choosing carefully to ensure minimum harm to the environment and maximum cost benefit. Only then would we start to consider the benefits of high technological solutions, starting with biomass heating systems, passive solar water heating, photo-voltaics, wind turbines, heat pumps etc.

While these new technologies are now becoming more affordable, simpler, cheaper and less obvious things can have a big influence, such as sourcing materials locally in order to reduce the environmental impact of transport, and reusing reclaimed materials wherever possible. One of the most cost-effective strategies is to ensure that buildings are air tight.

A database of 'green' materials and suppliers is maintained, and materials are assessed to ensure that as far as possible they are produced with consideration for the environment, that they do not require large amounts of energy, or use toxic materials or produce toxic waste in their manufacture or final use.

Appropriate solutions are sought for each individual case, in order to optimise available resources. There is no reason why new buildings should not use cheap and readily available materials such as straw bales, or rammed earth without compromising quality. At all times primary consideration is given to the health and welfare of the end users, as well as construction personnel.
