Glad you appreciate the irony. 🙂
My statement that hardly any new builds are passive is true, that most people aren’t prepared to pay the extra is also true. If yours is to be passive it will be one of a handful in the country. Tell us more:
Do you reckon it’s better to use triple-glazed windows all round at your latitude or is there enough solar gain to make double glazing a better option on the south side?
What sort of insulation are you going to use: organic materials, recycled materials, the cheapest, high-tech insulators or… ?
Will you be using heat recovery from both ventilation and waste water?
Is the roof designed so it maximises solar gain in Winter and limits it in summer or/and will you be using shutters?
