Can you recommend a good Site for Info ?

Hi all, Been using Imeasure for a while now, really like the idea, and how I can see what's going on with our energy usage.

I would like to see if people have any idea's on ways that we can all save more energy/reduce co2 and ultimately costs. Does anyone have links to websites with relevant info, I know you could just google for them, But wouldn't it be nice to have a good source of recommended sites listed here as well ?

Things we have done so far to improve the efficiency in our home :-

1) New double Glazing, (95% energy rating, Opti-white front glass, Argon Gas Filled, and Pilkington K-Glass Inner with a 40mm gap) compared to our old 20yrs old wooden framed ones.

2) Cavity Wall filled, polystyrene balls type

3) Loft insulation, twice as much as recommended as its very blustery and large space

4) Underfloor Insulation using Kingspan boards 600mm thick.

5) New central heating boiler (not the best on the market but it claims to be A rated), all rads fitted with thermo valves, and digital room stat set at 20 oC max. ( it is on most of the day from 8:00 till 22:00 hrs, we do turn it off if the house feels warm, main reason for it being on all day is that I have a disabled partner and she tends to get cold quick, through lack of movement)

6) The Main living room is also Wall insulated with foam backed plasterboard on the gable end ( the end that gets all the weather)

7) Polystyrene roofing (old left over of the days when everyone used the cracked ice effect, its a fire risk really and should be removed but we did it back then in an attempt to help keep some heat in the house)

8) Flat roofs converted to pitched roofs and double insulated, with reflective kingspan and polywool.

9) All spaces between the dormers and windows fitting are also filled with kingspan.

10) Most of the rooms are Energy efficient bulbs 7w types, and only used when we enter the rooms, other than that they are off.

11) All Tv's are LCD type with energy modes on, so the back light dims automatically depending on room brightness.

Things we haven't done :

Left the Airspace between the lower and upper floors un-insulated due to moisture retention as some air flow is needed to keep the joists dry/stable. This is a real big bug bear for us as the majority of the heat we think is escaping from here, as the joists run from front to back and the wind that blows through them is amazing... was thinking of installing some ducted fans in there and make a small wind generator :)

So I throw it over to you, is there anything else you can think of, or know were doing wrong that could help us improve on our ratings.

As our average spend according to the new Imeasure is around £28 a week combined... is this good ?

The house is a 3 bedroom semi-detached built 1960's known as a dormer bungalow / chalet type

Thanks in advance :D
