HIRO Assembly – PDF Version

The HIRO Assembly in PDF is a Best Practice Guide for High-Performance Building Enclosures in Cool Temperate & Cold Climates (ASHRAE Climate Zones 4 – 8) where space heating requirements dominate.  Includes 14 building enclosure assemblies to construct a high-end home with Passive House principles in mind.

  • Three separate air barrier systems in Wall Type 1 (W1) to achieve extraordinary airtightness.
  • All critical air barrier materials are clearly labelled.
  • Primary air barrier materials are in red font.
  • Cost effective constructability and locally sourced materials.
  • R-Value Analysis with an effective R-value for each assembly for energy modelling or building permit application requirements.
  • Moisture management guidance is provided with the water-vapour permeance of each material and vapour retarder class notifications.

Description

The HIRO Assembly in PDF Format is engineered for Cool Temperate & Cold Climates (ASHRAE Climate Zones 4, 5, 6, 7 & 8).  Includes R-Value Analysis and moisture management guidance for all opaque building enclosure assemblies including an above-grade wall, below-grade wall, sloped roof options, roof deck options, wood floors, and slab-on-grade.

The following opaque building enclosure assemblies are included in HIRO Assembly.

  • W1 Exterior Wall (R-48)
  • W2 Exterior Foundation Wall – Below Grade (R-53)
  • W3 Exterior Foundation Wall – Above Grade (R-36)
  • W4 Exterior Insulated Concrete Form (ICF) Foundation Wall – Below Grade (R-59)
  • W5 Exterior Insulated Concrete Form (ICF) Foundation Wall – Above Grade (R-43)
  • R1 Sloped Roof – Unheated Attic (R-70)
  • R2 Sloped Roof (TJI) – Vented Cathedral (R-42)
  • R3 Sloped Roof (Truss) – Cathedral (R-71)
  • D1 Roof Deck – Vented (R-42)
  • D2 Roof Deck – Inverted (R-56)
  • F1 Floor – Unheated Basement (R-57)
  • F2 Floor – Recessed (R-43)
  • F3 Floor – Cantilevered (R-44)
  • S1 Slab-On-Grade Floor (R-81)

Overview of what’s included

  • HIRO Assembly includes 14 opaque building enclosure assemblies.
  • R-Value Analysis with an effective R-value of each assembly for energy modelling or building permit application requirements.
  • All material layers are generic so a range of approved products can be sourced.
  • Moisture management guidance is provided with the water-vapour permeance of each material and vapour retarder class notifications.
  • All critical air barrier materials are clearly labeled.
  • Primary air barrier materials are in red font.
  • Integrated notes to clarify possible modifications without disrupting the moisture management strategy.
  • Easily modified to increase thermal resistance to meet project requirements.
  • All assemblies comply with prescriptive thermal performance requirements for both ASHRAE Standard 90.1-2010 and National Energy Code of Canada for Buildings (NECB) 2011.

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.
