Low energy buildings are not about bolt on technologies or cross flow ventilation. Natural ventilation is inappropriate for office buildings or homes, it is uncontrollable, not acoustically sealed, dosent filter air or manage humidity. Humidity is our biggest building defect in Ireland. Natural Ventilation does not deal with those clammy wet summers day.
The Deap software looks simply at energy balance, Passive house measures performance. The cost of a building should be measured over a couple of decades with even conservative energy price increase estimates. Its not enough to simply leave it to the plumbers and the electricians. A building needs to be designed around comfort and future proofed so as it dosent become a lead weight around the clients necks. Have architects realised that the days of churning out sub standard speculation stock has ended.
