Window Energy Balance #354

Closed ghost closed 4 years ago

ghost commented 6 years ago

It would be useful to have the gains and losses from the windows in the fabric page in the same units - for assessing the energy balance.

(If possible, totalling up each at the bottom of the table would also be useful).

I am googling with no result, how do you get to W/K from W for the gains? In fact it doesn't makes sense to me that light gains and heat losses can have the same units

I have added the totals to the bottom of the tables

Ok, can see why this would be confusing. Both gains and losses (which are both about heat) should really be in kWh/year - so you can make a comparison. Ideally per window and per orientation. This would allow you to make a judgement about the size of windows and amount of glazing. e.g. sometimes can be a good idea to decrease or increase glazing on a particular facade to improve the overall energy balance of the building. In any case, not a priority.
