Now, while I am having work done (by "professionals" (hopefully))
for CH and loft I would like to incorporate as many energy-saving /
energy-generation mechanisms as possible.

I will check all the obvious like quality of insulation and
eliminating damp. However, I would like to find which other "eco"
techniques are effective and have a pay-back of say 10 years or less. I
have thought of the obvious such as some kind of solar panel to
pre-heat water, ground heat collection, water butts, wind generator.
Are there any good Web sites that give "long-term" analyses of these
techniques such as cost of installation and maintenance, effectiveness,
usefulness in SE UK (e.g the amount of "collectible" power form the
wind), reliability etc. etc. ?

Thanks

To kick off...

insulation insulation insulation
solar hw can pay back but too often doesnt.
solar warm air can give good ROI
underground pipes can give a nice return as an ac substitute
solar pv forget it
windgens in inhabited areas forget it
shower drain heat exchanger can pay back well
passive cooling avoids much ac
deciduous climber on house walls producng fruit gives summer colling &
food, but must be kept off the roof. High ROI.
