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.

SITE & CONTEXT

EAST HILL INFILLLEED FOR HOMES PLATINUM RATED DUPLEX

Replaces 1100 sf home with duplex that can potentially accommodate 4 dwellings.

5 x increase in floor area while only increasing bldg foot print X2

Close proximity to services, amenities, and alternative transportation ( ½ mile of > 14 services/amenities

Architectural continuity - maintain valued character of neighborhood

Semi public space for active community engagement + eyes on street

Xeriascape planting + permeable surfaces

Harvested rainwater for irrigation

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

SITE /CONTEXT Increase Density -Subdivide

0.3 ac property to allow two single family dwellings.

Re-use - relocate and renovate existing single family home on site

Add new dwelling - design based on passive solar assisted heating + cooling by natural ventilation. SITE SPECIFIC DESIGN

respect scale and character of neighborhood while re-invigorating architectural language

Position homes closer to street. Include active outdoor spaces for community engagement & eyes on street
