Question
Applicability
Answer
Select applicable:
- Yes — work is underway or has been completed
- Yes – we have done an assessment
- No
- N/A – New building is already at high-performance OR No systems or equipment in the owner/landlord’s control
- Not Applicable – new building is already at high-performance
Description
A high-performance building envelope aims to enhance occupant comfort, improve controllability and minimize the transfer of thermal energy between the outdoors and indoors.
Strategies, such as air tightness, shading, triple-paned glazing and increased insulation can be implemented to reduce energy consumption and GHG emissions while improving thermal comfort and reducing the mechanical system Requirements.
Requirements
- Identify the major envelope upgrades from the assessment, condition or deep retrofit studies that have been implemented
- Document extent of implementation
Also see Other Notes
Documentation
- Describe measure(s) implemented, the benefit and potential savings impact
- Evidence of implementation through photos, as-built drawings or other proof
Adapted BB3 Question
Question 01.01.03 – Does the capital plan include measures to ensure continuous improvement of the energy efficiency of the building envelope?
Question 01.05.07 – Are 75% of the building’s exterior windows considered efficient?
