Eco-friendly building practice and technologies
I am well versed in most of the 'green' technologies that are
currently employed in the building trade.
I have extensive experience with low energy lighting both CFL and LED and can either recommend fixtures and fittings that last
or supply to your specification.
As a rough guide CFL bulbs have an energy to light ratio of 1:5
compared to standard fitments, whilst LED offer up to 1:10 saving.
In
addition there are a variety of intermediate technologies such as
xenon and other halogen bulbs that offer smaller savings without
having to change fittings or transformers. Colour Temperature is also
a consideration.
I suggest the use of Luxeon or Cree single filament bulbs if LED
lighting is to be used for longevity, quality of light and aesthetic
appeal. I can supply as well as fit.
In older properties insulation can be a challenge to achieve a
performance that home owners strive for. Experience has taught me that
with thought and careful choices older properties can be made to
perform close to
When insulating, I can calculate
U-values for any given project and provide advice on how to reach
statutory requirements for the envelope in refurbishments, extensions
and
new builds.

These savings are year on year, and
continue to be made. Even the most expensive of installations will
only take a few years to repay its costs, in addition to
increasing the value of your home. |
