Performance Requirements
Sustainable Design Requirements
1 LEED Accreditation
- The University of Lethbridge requires that all new building design and construction follow the requirements of the LEED process. It is not the intention to have all applicable projects accredited but the practice and procedures that follow with LEED accreditations shall be maintained for all projects. The University will decide whether a project does not warrant obtaining LEED certification.
- The University of Lethbridge requires that the Prime Consultant conduct a LEED energy charette with Physical Plant for all projects. The purpose of the charette is to review and refine a preliminary LEED checklist along with potential energy savings to be pursued by the design team.
- The University will only pursue LEED points based on merit and value.
2 Energy Management
The University requires that all designs, whether large or small, adhere to a strict energy management policy and procedure. All energy conservation methods shall be considered and reviewed prior to finalizing the design. Items to be considered include but are not limited to:
- Free cooling
- Heat recovery (i.e. heat wheels, etc.)
- Variable frequency drives (on fans, pumps, etc.)
- Variable flow systems
- High temperature differential systems (hot water and chilled water systems)
- Variable air volume systems
- Demand control ventilation using carbon dioxide (CO2) control
- Time of day scheduling
- Thermal storage (if feasible)
- Instantaneous hot water heating
- Low water consumption plumbing features
- Displacement ventilation
- Low electrical consumption high lumen output light fixtures
- Occupancy control
- Energy management considerations should provide a simple pay back. The maximum pay back of any option will depend on the nature of the equipment and life of the materials being considered.
- High efficiency VFD compatible motors shall be used for all applications
