Building Performance Starts at the Site: Early Decisions That Shape Architectural Outcomes

Some of the most important decisions affecting building performance occur before plans and elevations are fully developed. Site grading, finished floor elevations, drainage strategy, solar orientation, envelope exposure, snow accumulation patterns, access requirements, and relationships to surrounding context can significantly influence energy performance, durability, constructability, and long-term building behaviour. Yet these decisions are often treated as technical coordination exercises rather than core architectural considerations.

This session examines how early site and building planning decisions shape project performance across contemporary architectural practice. The webinar explores how architects coordinate topography, climate response, building envelopes, accessibility, servicing, and landscape relationships from concept through technical design. Participants will gain practical insight into how relatively small early-stage decisions can substantially influence building quality, resilience, construction efficiency, and long-term operational performance.

Key Topics Discussed:

• Site planning as a building performance strategy
• Finished floor elevations and building relationships to site
• Drainage and stormwater considerations
• Snow accumulation and climate-responsive design
• Solar orientation and passive environmental response
• Building envelope exposure considerations
• Accessibility and topographical constraints
• Retaining walls and grade transition strategies
• Landscape and architectural integration
• Coordination with civil and structural teams
• Constructability and site-related project risks
• Lessons learned from contemporary projects
