Outline
• Climate Action Plan
• Campus energy projects
• Energy use in labs
• Green Labs program
• What you can do
• Freezer pilot
UBC adopted its Climate Action Plan in 2010, committing the Vancouver campus to aggressive greenhouse gas (GHG) reduction targets of:
33% below 2007 levels by 2015
67% below 2007 levels by 2020
100% below 2007 levels by 2050
(or “net zero”)
Climate Action Plan
Targets
• Measure emissions
• Offset emissions
• Report on plans and actions to reduce emissions
BC Carbon Neutral Government Regulation
Greenhouse Gas Reduction Targets Act
GHG Inventory - Vancouver campus - 2012
Total offsettable emissions = 60,715 tCO2e
Buildings 47%
Fleet 1%
Paper 1%
Commuting 25%
Staff & Faculty
Air Travel 16%
Building Lifecycle
9% Solid Waste
1%
Other 51%
• Three key projects will achieve the 2015 goal:
Bioenergy Research and Demonstration Facility (9%)
Steam to Hot Water Conversion (22%)
Continuous Optimization and behaviour change (10%)

Building Tune-Up & Behaviour Change
• Laboratory space uses 10
times as much energy as
other types of space on
campus
• Reason: high ventilation
rates & energy intensive
research equipment
• Each fume hood uses the
energy of 3.5 homes
Energy consumption in labs
Energy consumption in labs
Lab buildings consume 49% of campus energy
Ventilation 49%
Plug load 16%
Lighting 9%
Other 27%
Green Labs Program
• Stage 1: Pilot Projects
– Behaviour change (Shut the Sash)
– High performance fume hood renovation kit (Chemistry East)
– Lab re-commissioning (Chemical & Biological Engineering; NCE)
• Stage 2: Analyze Results
• Stage 3: Program Implementation
Opportunity to improve lab safety, air quality and performance – and pay for it all with energy savings!
• Reduce fume hood face
velocity to 90 ft/min (new
EH&S regulations)
• Chemical storage cabinets
rather than using fume hoods
for storage
• Decrease air change rate
during unoccupied hours
(night setback)

What Can You Do?
• Where possible, use natural light
• Use a task light, if you’re working alone
• Turn off lights when last one out

What Can You Do?
• Purchasing:
– Buy energy efficient equipment
– Share equipment with others
• Computers: Power Settings
• Ovens/Incubators/Shakers: Turn off OR use timers
• Be Freezer Smart: Clean and manage your freezers

What Can You Do?
• Vacuums: Eliminate vacuum aspirators
• Purified Water: Only use it when you need it
• Autoclave/Dishwashing: Full loads only

Campus Sustainability – Freezer Pilot
Why focus on freezers?
• Freezers alone account for ~ 2% of campus energy use
• Energy used for 1 NEW ULT = 1 single family home
• Adds heat load to buildings
• Unmaintained freezers use 12-25% more energy
Bottom line: Proper freezer management minimizes operating/energy
costs, reduces freezer failure and ensures optimal freezer performance
Campus Sustainability – Freezer Pilot
To develop a freezer management program that reduces energy use from freezers
Purpose
Turn this Into this
Campus Sustainability – Freezer Pilot
• Freezer Maintenance: Clean coils, defrost and check seals on freezers/fridges regularly
• Freezer Space Management:
– Consolidate samples and discard unwanted & unmarked samples
– Inventory all sample boxes and organize shelves
– Fill open space with water jugs
• Temperature Tuning: Raise temperature setpoint by 10°C in freezers, if possible
• Retire or Replace Freezers
