Benchmarking with Energy StarBenchmarking with Energy StarSubmetering required for Energy Star benchmarking of Campuses.

College and University campuses can have quite distinct characteristics. Campus buildings include:(1) dormitories,(2) buildings with classrooms and office space(2) buildings with classrooms and office space, (3) gymnasiums, (4) dining halls, (5) facilities with classrooms, office space, and energy-intensive laboratories. ( ) , p , gy

Sub-metering permits comparisons of energy use among buildings within these various categories.

Dormitories and Classroom/Office space make up the largest square footage on p p g q gmost campuses, suggesting that schools might give priority to sub-metering facilities in these two categories.

Optimize Supply

Eliminate Waste

• Turn it off when not in use (printers, task lighting etc.)

• Occupancy sensors for Lighting and HVAC• Computer shutdown and power management• Optimize schedules to reflect occupancy• Optimize setpoints – heating and coolingg g• Outdoor air reset schedules

Most Frequent Measures

• The building is naturally ventilated and uses a geo-exchange system and water source heat pumps for heating and cooling.

• Five wind towers pull air upward through the building; undulating• Five wind towers pull air upward through the building; undulating concrete roof increases pulling power of wind towers by increasing wind velocity and sensor-controlled windows bring air into the building.into the building.

• Waste heat is captured from exhaust air and the building's exposed cast-in-place concrete and high-performance glass aid i t f d tin energy transfer and storage.

Employee Awareness Programs

Workplace Conservation Awareness (WCA)Workplace Conservation Awareness (WCA) Programs

People, not just technology, control, use and save energy.

WCAP is an staff driven energy awareness and behaviouralWCAP is an staff-driven energy awareness and behavioural change program. It is about engaging staff and students and harnessing their abilities to reduce energy . . . every day.

Community Based Social Marketing

WCA programs are based on Community Based SocialWCA programs are based on Community Based Social Marketing (CBSM) techniques.

CBSM is a “brand” of social marketingCBSM is a brand of social marketing developed by Douglas Mackenzie-Mohr
