modern houses should be well-insulated, using heat exchange ventilators and heat pumps get proportionately more efficient in these conditions. i will be shocked

modern houses should be well-insulated, using heat exchange ventilators and heat pumps get proportionately more efficient in these conditions. i will be shocked if this is ever viable economically.
- Retric 3y agoOne possibility you lose from a well insulated house is the heat collection potential of your roof on a cold day. The roof is receiving close to 1,000w/m2 and that energy is just wasted. Passive houses use a lot of tricks around the angles light enters a home and skylights etc to collect that energy, but a system that uses little energy and doesn’t have moving parts so it can last the lifetime of the home should allow for more options and thus lower costs. PS: Solar thermal systems work well and have a fairly short payback period, but involve both moving parts and fluids.
