 Slab: R45- R55
 Windows: Triple Glazed, Argon, selective
coatings depending on exposure, R7.2
(overall)
 Air Sealing: <0.6 A.C./hr

Performance – roughly 29 kWh/m2




    Annual Heating Cost (electric): $422
Super Insulating Existing Walls

Envelope: Lessons Learned
• Residential trades
  challenged by typical
  commercial details –
  cost/quality
• Spray Foam – must have a
  secondary air barrier if
  attempting to get lower
  than 2 ACH
• 4” of external insulation
  results in labour intensive
  window/door installation
• Infill or tight city lot – carry
  expense for lifts

Lessons Learned:
Roadmap for a Deep Green Retrofit

   •   Shared Commitment to Ambitious Goals
   •   Strong Team, Committed to IDP, must
       have experienced trades at the table
   •   Sweat the Details
   •   Double the design/procurement time
          OR double your budget
   •   Find experienced trades who like problem
       solving.
   •   Expect site oversight to be more diligent
   •   Contracts with subs through GC need to
       be clearly defined

  • #35: Zero Waste – reusing and recycling building waste, composting, less packaging♣ Approximately70% of the existing building (by area) will be retained and renovated in the project. This represents more than 95% of the building’s mass.♣ Salvaged wood and bricks from the demolition will be re-used in the construction project.♣ Demolition waste will be sorted and separated for re-use and re-cycling with the goal of a 75% diversion rate.♣ Construction waste will be sorted and separated for re-use and re-cycling with the goal of a 95% diversion rate.♣ Post construction the reduction efforts will include purchasing decisions that reduce packaging and waste; swapping, sharing, and giving/receiving used items; recycling in the municipal program; backyard composting; and composting within the municipal program. A baseline will be established in the first year that has 80% diversion by weight, and then a plan for future improvement will be established for 95% by 2020.

  • #51: Steel or wood doors with the strip that holds the IGU in place, PVC in drywall return for windows., HCFC’s in blowing agent in closed cell spray foam insulation.IKEA kitchen – some formaldehyde (E1 standards).The building industry is largely responsible for many of these materials and chemicals in use. For example, approximately three-quarters of all PVC is in building materials. Some of the other items on the list such as cadmium, lead, mercury and phthalates are also used as plasticizers and stabilizers for PVC.Living Building Challenge recognizes that it is a tall order to eliminate the Red List in all cases due to current market limitations. There are several program exceptions that are footnoted in the Standard. As a last resort, the product is allowed to be used. However, when faced with imperfect solutions, project teams must communicate with manufacturers to share expectations about product ingredients. A letter must be sent to the manufacturer stipulating that the product purchase does not constitute an endorsement – and include a statement that requests that the company stops using the Red List material.
