Certified Passive House Planning
Homesol Building Solutions continues to be on the leading edge of sustainable design with Passive House, a building performance standard that results in a phenomenal reduction in heating and cooling energy compared to a standard-built new home.
As one of Canada's most experienced energy modeling companies, fully trained as Certified Passive House Consultants with both European and North American qualifications, Homesol can determine exactly what you need to do to reach the Passive House standard. If you want to achieve the highest level of energy efficiency possible for your building project, we're the people you want to talk to.
We're based in Eastern Ontario, but we gladly serve anywhere in North America and the world. Contact us to get started on your Certified Passive House!
Homesol's Passive House Design Process
Stage 1: Preliminary Design Meeting and follow-up
A preliminary meeting (in-person or video conference) of approx. 1-2 hours will be held, covering the general outline and proposed scope of the project. The key areas that will be discussed include:
- Building site
- Orientation and location
- Preliminary design and geometry
- Budget and energy performance target
A follow-up summary of the meeting will be provided including feasibility and the proposed design solutions to Passive House.
Stage 2: Completion of Construction Design Consulting, PHPP Analysis & Plans Verification
If the decision following the preliminary meeting is to move forward with Passive House, Homesol will work with all the key players in the project - Client, Architect/Designer, Builder – to assist in developing a design that will meet the Passive House criteria. Multiple iterations of the Passive House Planning Package (PHPP) energy modeling software will be used to find the most cost-effective and buildable solutions, concluding with the development of final construction-ready drawings by the design team.
The key components that need to be determined at this stage are:
- R-values and construction details of all the building assemblies
- Airtight construction details
- Thermal-bridge-free construction details
- Window sizing, thermal and solar gain characteristics
- Overhangs and shading
- Ventilation system selection
- Lighting and electrical base loads
- Heating, cooling, domestic hot water and renewable energy systems
Stage 3: Completion of Site & Trades Orientation, Preliminary Air Leakage Test, Continual PHPP Updating
On commencement of construction, Homesol will hold a Site Meeting with the entire Project Team to explain the unique Passive House criteria and ensure a good start towards successful completion of the project. At this point a Solar Pathfinder shading analysis will be performed.
During construction Homesol will be available to answer any questions, and will make periodic visits to the site to ensure Passive House design criteria (insulation, thermal bridging and airtightness details) are being adhered to. A preliminary air tightness test will be performed as soon as the continuous air barrier is complete, before drywall, and if the mandatory 0.6 ACH50 airtightness is not achieved at this point we will provide diagnostic testing to determine leakage locations and ensure they are properly sealed.
Throughout construction the PHPP energy model will be continually updated to reflect any changes in the construction details.
Stage 4: Completion of Final Site Inspection, Air Test, Ventilation Commissioning, PHPP Verification and File Submission for Certification
A final site inspection on completion of the project will verify that the certification file for submission matches what has been built or installed. The final air test will be performed, and the air flow rates of the ventilation system will be measured and recorded. This Quality Assurance process ensures that the building will perform as modeled.
