The energy performance targets, expressed in kWhr/m2/yr, are identified in a project’s Design Brief and are based on the uses within the building. A project’s design team will be given an opportunity to review and discuss the targets and their implication for building design; after final agreement on the targets the project shall be designed to meet this required performance.
Refer to the UBC LEED Implementation Guide for the current mandatory points required for Energy & Atmosphere Optimize Energy Efficiency.
UBC’s Approach to Energy Design
UBC seeks to design and construct buildings that minimize energy consumption and are optimized for renewable energy sources. Building energy demand should be reduced through the following hierarchy, which can be applied across all building types:
- Use less energy – apply passive design strategies
- Passive design strategies have significant potential to decrease energy use in buildings and to improve users’ comfort. An integrated design process is critical to ensure that the passive design strategies are considered at the appropriate time and in the appropriate sequence and combination. Consider: building orientation, building shape and massing, space planning related to passive energy savings strategies, window and glazing design and exterior solar management (see Vancover Campus Plan Section 2.3.10).
- Maximize thermal performance and air tightness of the building envelope.
- Use energy efficiently – incorporate efficient and right sized active systems
- Design low temperature radiant systems to use lower grades of energy. Connect building to the District Energy system or design to be District Energy compatible where applicable.
- Use heat recovery opportunities.
- For laboratories: use the Environmental Performance Criteria from Labs 21.
- Use low- and zero-carbon sources of energy.
- Minimize electrical peak demand to reduce future campus electrical infrastructure. Avoid the use of electrical baseboard heaters.
