Mechanical systems play a critical role in residential building design, yet HVAC coordination is often addressed too late in the design process. In many jurisdictions, including Ontario, permit applications for new homes and additions require detailed HVAC design documentation such as heat loss and heat gain calculations, duct layouts, and equipment sizing. When mechanical systems are not properly coordinated with the architectural design, it can lead to permit delays, costly revisions, and construction challenges.
This webinar explores how mechanical systems should be integrated into the residential design process. Participants will learn how HVAC requirements influence building layout decisions, including room configuration, ceiling spaces, and duct routing. Using Ontario permit requirements as a practical example, the session highlights common coordination issues between architectural drawings and HVAC design documentation, helping attendees avoid mistakes that slow approvals or create redesign work during permit review.
Learning Objectives:
- Understand how HVAC design requirements influence residential building permit applications.
- Identify the role of heat loss and heat gain calculations in residential HVAC design.
- Recognize how duct layouts and mechanical systems affect architectural floor plans.
- Learn how to coordinate HVAC systems with residential building design.
- Avoid common documentation and coordination mistakes that delay permit approvals.
