Description

The HIRO Detail Package in PDF Format is engineered for Cool Temperate & Cold Climates (ASHRAE Climate Zones 4, 5, 6, 7 & 8).  The building enclosure uses a standoff wall consisting of a conventional 2×4 framed inner wall (load-bearing) with vertical wood I-joists (9.5” deep) exoskeleton fastened through the exterior wall sheathing into the 2×4 wall studs.  The structural frame uses standard framing techniques with exterior wall sheathing, interior gypsum wallboard with standard platform framed floors and interior wall junctions.  The primary air barrier system uses the exterior plywood wall sheathing with taped joints to maintain air barrier continuity.  The secondary air barrier system uses an exterior sheathing membrane (WRB).  The interior vapour control membrane is shown as an optional air barrier.  The design includes multiple roof options including sloped roofs and roof decks (inverted and vented assembly options).

Overview of what’s included

COMFORTABLE

Discomfort is felt when your body radiates heat to colder surfaces around you. This does not happen in a Passive House. Super-insulated building enclosure including high performance windows ensures comfortable interior conditions with no cold surfaces on the walls, floor, or roof. No temperature swings or drafts. The constant interior temperatures provide a new level of comfort – once you experience it you won’t go back.
BETTER INDOOR AIR QUALITY
Heat recovery ventilation (HRV) system delivering constant fresh filtrated air resulting in better indoor air quality, free of mold and lower levels of carbon dioxide, creating a healthy space to live.
SOUNDPROOF
Super-insulated and airtight building enclosure eliminates nearly all street noise when all windows and doors are closed. So you can get back to Netflix in peace and quiet.
DURABLE
Super-insulated and airtight building enclosure that’s thermal bridge free with controlled ventilation prevents condensation from forming on interior surfaces. A structure free of condensation damage will ensure an extraordinary service life.
HIGH PERFORMANCE
Passive House buildings consume 75% to 90% less heating energy than conventional homes. Save money on your monthly expenses by reducing your energy consumption.
