next generation infill housing
DESCRIPTION
A Recent presentation of strategies for sustainable infill housing in the Okanagan. The East Hill Infill follows a prescriptive (LEED for Homes) approach, while the Mission Infill utilized a 'common sense' strategy of passive solar assisted heating and natural ventilation. The former project achieved a LEED Platinum designation while the latter achieve an ENERGUIDE 81 rating.TRANSCRIPT

CONSTRUCTION
Simplicity– light stick framing between ICF (insulated concrete form) walls.
Exceptional R values for all assemblies ( R 30 walls ,R60 roof )Exceptional windows ( triple glazed)
Durability and improved FRR of concrete demising walls
Significant reduction of material waste
Clear span will allow for future plan variations and adaptive re-use
Adaptability – anticipates extrapolation into row housing configuration. Design anticipated a variety of roof truss shapes that will allow for different orientations
