Net-Zero Ready Home in Whistler
|
|
We are excited to showcase this beautiful high-performance Net Zero Ready home in Whistler by RDC Fine Homes.
The home was designed by Whistler’s Brigitte Loranger.
What are CHBA Net-Zero Homes?
CHBA Net-Zero Homes are homes designed, modelled, and constructed to produce just as much renewable energy as they consume annually. Net-Zero homes are up to to 80% more energy efficient than a typical new home build. To put this into perspective, the EnerGuide score for a Net-Zero house would be 0 GJ (gigajoules) per year, measuring the natural gas energy content. Comparing this to an average home score, Net-Zero homes are 8 times more efficient than average homes.
A Net Zero Ready home, is a home that has met the CHBA Net Zero criteria, but the onsite renewables (in this case Solar PV panels) have not been installed yet. This allows for the homeowners to install the panels later when the budget allows for it.
Characteristics of this home:
- Walls: 2” Neopor exterior insulation BASF HP wall – Effective R-25
- Foundation: ICF Effective R-22
- Ceilings: Exterior insulated + 2lb spray foam Effective R-50-60
- Windows: Triple glazed USI 0.90 SHGC 0.16
- Exterior air barrier + AeroBarrier
- Airtightness: 0.98 ACH @ 50 Pa
- Heating: Dettson electric furnace + Air source heat pump
- Domestic hot water: Rheem hybrid electric heat pump

2022 VBBL Update For 1-3 Storey Residential Buildings
|
|
The City of Vancouver has introduced changes to the Vancouver Building By-law (VBBL).
The City of Vancouver has introduced changes to the VBBL that includes updates to the energy compliance requirements’ for new construction of single family and multi-family residential buildings three storeys and under. These changes went into effect on January 1st, 2022 and will apply to all new permits after that date
The update introduces:
- incrementally greater performance requirements for various building components
- stricter limits on the use of gas-fired equipment, and additional paths for demonstrating energy compliance
- to provide more flexibility in meeting specific targets
These changes will have an impact on what types of building systems are specified, and how a low-rise residential building is designed and documented. It is important as a builder, developer, or individual involved in a new 1 – 3 storey residential building to be aware of these changes and apply them to an project’s permit application submitted after January 1st, 2022.

Built Green Launches Net Zero Energy+ Program for Single Family New Homes
|
|
Kicking off the new year, Built Green Canada launches its Net Zero Energy+ program for single family new homes, a new level of achievement within the organization’s long-held, industry friendly green building program.
By 2030, the Government of Canada aim is that all provinces and territories adopt a net zero energy ready building code. For our context, “net zero” refers to a home producing as much energy as it uses in a year.
Builders pursuing this certification are required to pass the training course, BUILT GREEN Net Zero Energy for New Construction, and may work with any Energy Advisor licensed through NRCan who has also passed the training. One of the organization’s mandates is around offering industry options, instead of a prescriptive approach, and this extends to process, as well as the programs themselves.
For more information about the program, click here.

Normalized Leakage Area (NLA)
The NLA is calculated by dividing the Equivalent Leakage Area (ELA) from a fan test by the area of the exterior envelope of the house. The ratio of the equivalent leakage area at 10 pascals (ELA@ 10 Pa) to the area of the building envelope, where the area of the building envelope is defined as all floors, walls (including doors and windows) and ceilings (flat or sloping) that are corresponding below, above, and adjacent to unheated spaces and spaces heated to less than 10 C, and are based on interior dimensions; express in cm^2/m^2 (sq. in/sq.ft).

Please remember to book your mid construction and final tests at least two weeks in advance!
Friendly reminder to all builders needing to book their mid construction and final blower door tests. Please give us a call two weeks in advance to ensure we can have you on the schedule and to ensure a quicker turnaround time for your reports! We recommend contacting us for your mid construction test when insulation has started.
