The PassivHaus Institute has pioneered a standard for low energy buildings. It includes very low energy usage and ways of achieving this. The word is derived from the idea of buildings which are fundamentally low energy and passive solar heated rather than using extra gadgets to heat them.

Advantages of timber
Constructing with FSCForest Stewardship Council (who accredit timber) timber (or another accreditation organisation such as PEFCProgramme for the Endorsement of Forest Certification. See their web site) is potentially one of the greenest ways of building for several reasons.
Timber itself captures and locks up CO² as it grows and keeps [...]
multiple glazing Types of sealed unit
As a minimum try to use sealed units with a spacing of 16 or 18mm. rather than 6mm. This is the optimum gap for heat insulation. However the frames need to have sufficient rebate for this. See window design. Use a filler of argon gas rather than air. [...]
sourcing timber
Sourcing sustainably produced timber and manufactured timber building products requires checking the following -
Was the timber sustainably grown? How far has it travelled? Does it contain chemicals such as adhesives or timber treatment?
