Traditionally, domestic hot water has simply been a choice between a combi boiler or a vented system (with the odd Point of Use water heater thrown in).
With water saving design, and zero carbonbit of a slippery fish. It tends to mean that a building uses no carbon (oil, coal, etc) to heat it (meaning […]
Existing houses present a much greater challenge than new ones in terms of energy saving. However in terms of reusing building materials they often provide better opportunities.
Patrick and Fiona run a very pleasant bed and breakfast near Nelson, Caerphilly and their house has been the subject of much renovation and extension over the […]
Bringing existing houses up to a high standard of energy efficiency is a much greater challenge than with new ones.
This particular example of self build eco renovation is outstanding because of the way it will achieve a net zero carbonbit of a slippery fish. It tends to mean that a building uses no […]
The Tree House in Clapham, London is a recently completed and very elegant example of a self build detached house. It has, on occasion, been open to the public as part of the London Open House programme. Situated on a small urban plot of land dominated by a large sycamore tree it has taken […]
Jim and Jo Monahan are nearing completion of their passive solar house in Spinningdale, Sutherland. This is a timber frame,self build project which utilizes roundwood for many of the structural members. This is a way of using timber at its maximum strength because it is not cut across the grain. The timber […]

In the UK there is plenty of heat energy to be harvested; it just doesn’t all come at the right time. Ideally you save all the surplus heat that comes along and then use it when there is a shortage.
Winter / summer balance
At one extreme is the interseasonal heat store such as was […]
High thermal massthis is about how much heat something can absorb - so it involves its specific heat capacity and its volume. It can be useful for levelling out the peaks and troughs of temperature within a house. See the page on
thermal mass is generally seen as a useful quality in a building because it can be utilised to trap and save any spare heat which might turn up.
It can also do the reverse equivalent for coolth during hot weather. This quality is utilised in passive solar design, including the PassivhausSee more […]
