Sample interview questions: How do you approach designing for efficient building envelope insulation and thermal performance?
Sample answer:
-
Zoning and Compartmentalization:
- Segregate spaces based on their usage and thermal requirements to minimize heat transfer between different zones.
- Use insulation and air barriers to minimize thermal bridging between different building elements.
-
Continuous Insulation:
- Apply a continuous layer of insulation on the exterior of the building envelope, minimizing thermal breaks and heat loss.
- Ensure proper insulation at all building junctions, corners, and penetrations.
-
Airtightness and Vapor Control:
- Design a continuous air barrier system to prevent air infiltration and exfiltration, reducing heat loss and moisture problems.
- Incorporate vapor control layers to manage moisture movement within the building envelope, preventing condensation and mold growth.
-
Window and Door Design:
- Select energy-efficient windows and doors with high thermal resistance and low air leakage.
- Consider triple-glazed windows or windows with low-emissivity (Low-E) coatings to improve thermal performance.
-
Roof and Ceiling Insulation:
- Install adequate insulation in the roof and ceiling assemblies to minimize heat transfer through the top of the building.
- Use reflective materials or radiant barriers in attic spaces to reduce heat gain during summer months.
