The cost shock kept us occupied for some weeks. It gave us time to reflect, which was very much needed (our house search was going slowly at the time). We were able to put our finger on a fundamental flaw in my thinking.

For example: A tight building envelope, or a super-insulated home, is very important and a top priority for us. It significantly reduces the building energy consumption and operational cost. It further allows scaling back and cost-savings on mechanical equipment, such as heating and cooling.

With that said, why exactly do I want radiant floor heating in a super insulated home (see also 05/07/2009 post)? It’s like I am searching for a hybrid car with eight wheels, just because I like wheels. It is counterproductive and will have a negative effect on the gas mileage. Four wheels will do the job! And you know what? Two wheels will do an even better job – that thing called bicycle. Not only would I not burn gasoline or require all that energy that goes into the production of the automobile, but I get the needed fresh air and exercise and have the opportunity to wave hello to my neighbors while I am pedaling by.

Why was I focusing on radiant floor heating (and some other fancy but costly items), if all I really need is a solar collector, a hot water thank, and a very simple radiator system that only needs to come on occasionally?  Time to rethink and remember basic sustainable design principles!
