I gave a presentation earlier this week on ventilation and indoor air quality, and someone messaged me afterwards thanking me for highlighting the importance of this way of living because they’ve lost 5 FAMILY MEMBERS TO COVID. 5!! Holy shit.

Though I can see someone arguing to hit the energy metric anyway despite the higher ventilation.
@nb_covid_info Okay I get that the existing act is intended for outdoor air quality; occupational health leaves a big gap for the general public (non-workers) in buildings. Instead of dumping it altogether, NB gov't should take the lead on legislation that protects the public indoors.

Ultimately - where exemptions are not agreed - local (national/state) standards must also be satisfied …which is one reason why PH has been also successfully adopted in the USA.

Surprised @the_iPHA criteria for Ventilation so poor 20m3/he per person Especially in non residential High density occupancies Like schools What is the point of certification If the building is not Healthy 🤷♀️
@ScottFarbman Are you considering the lifespan of the systems? My understanding is that geo should last twice as long as ASHPs
@ScottFarbman @cornoisseur Thanks. I ask because while a bit over a tonne oer well sounds like a lot, that's in the ballpark of a kW of PV panel... And I suspect the heat movement will save more electricity over the project life than a PV panel produces.
@ScottFarbman @jonesbeall Any way you can run ac off renewables? We did a similar project in Australia and geo thermal didn’t work at both embodied and total demand (the project was too small and high performing to need consistent heat or cooling so kept turning on and off) we went with a vrf and solar
