Design-build and Load Calculations

Our design-build HVAC service covers concept development, TECA F-280 load calculations, equipment selection, duct layout to TECA standards, and a permit-ready summary for city review. We coordinate with your builder and trades, then carry the design through commissioning. This end-to-end design-build HVAC approach reduces rework, keeps budgets predictable, and aligns installation with the approved documents.

We perform TECA F-280 heat loss and heat gain calculations using project drawings, orientation, insulation values, window data, and occupancy. On site, we verify assumptions where needed. The results drive equipment sizing and duct design, not rules of thumb. Your permit package includes the required load calculation summary where the city requests it.

Yes. For Delta and Metro Vancouver municipalities, we prepare a permit-ready summary of the load calculations and design notes, and we include permit fees in the quote and schedule inspections. Our HVAC permit package streamlines plan review, because sizing, airflow, and equipment data appear clearly. Where a summary is required, we submit it with the application.

We right-size using TECA F-280 results, duct design, and verified airflow targets, not tonnage guesses. Static pressure is designed to land within 0.4–0.8 in. w.c. so the selected system delivers its rated capacity. This right-sized HVAC approach improves comfort, noise, and efficiency while protecting manufacturer warranties tied to correct sizing and commissioning.

You receive as-builts, a model and serial number list, startup checklists, and warranty information. When ventilation is part of the design, we provide balancing readings. The documentation mirrors the approved design-build HVAC plan, helping future service and warranty claims. It’s a complete closeout package you can hand to owners, strata, or project files.

Yes. During design-build and load calculations we compare equipment options, including heat pumps and dual fuel. We recommend the most efficient product for the job, then set automatic changeover using outside temperature. We do not provide energy savings modelling. This practical electrification consulting keeps code compliance, comfort, and budget aligned for Delta and nearby projects.
