Just looking to get some feedback on a house design. SOG, highly insulated, SIPS on exterior walls, flat roof with 2ft of blown in insulation, HRV, minisplit with ducted indoor unit. Image below and pdf’s attached. House is in southern Ontario, heavily treed lot. Climate zone 6.
A few questions;
– Should I put in a seperate Point Source hot water heater for kitchen sink?
– Basement? We are trying to keep our family close, and could always add on later when the kids get older.
– Are SIPS really worth it (~$12k)? Using for outdoor vapour barrier and R-40 (6.25in) insluation.
– Flat roof looking to use a thick 90mm EPDM/proactive trimming to avoid punctures.
