We have a nice new home that is well insulated, however we still have energy issues. As our first winter in our new home is almost over, we have discovered 3 key concerns about modern house building techniques. Our concerns are moisture, heating and cooling - taking into consideration that we only have underfloor heating and no air heat pump to cool the home down.
Basically because the home is so well insulated the moisture builds up; secondly the home is positioned so well for the sun that it gets very warm; and lastly its very tempting to crank up the heated floor at the peril of the resulting power costs.
Many of the homes around us that I've visited have different issues, they have downlights that have holes in them so that in the summer they get a lot of heat gain, which has their heat pump working over time to keep up - these holes in winter obviously allow hot house air from log burners or heat pumps to escape up into the cool roof cavity.
Have downlights change them to the modern alternative.
