yes solar heat gain is highly affected on west & south facing orientations, if you have passive cooling options such as awnings, solar shading, it'll help quite a bit.
yes - less leakage = better retention of cooling, my point is, you NEED cooling, if you have a PH and cheap out and NOT have cooling (i.e. a developer that gives zero f's)... then it's gg and be a case study
well made PH won't have leakage, it'll generally be warm until you cool it which it'll retain. in order to keep said cooling it needs to be, well ... cool ... it'll be magnified in MURBS ... for a SFD, where in addition to passive cooling you may get away with passive measure such as cross ventilation (creating natural airflow), but in this day & age, if you're doing a PH building, please for the love of God whomever lives in that building, add cooling - my 2 cents.
disclaimer - i'm not a sustainability engineer, but used to champion sustainable principles for projects b/c i'd rather buildings be lived in vs ticking a box & having abc certification
and ventilation for asian cooking? are you gonna achieve that by a ductless hoodfan with a charcoal filter?
i'll hop off my soapbox now
