A Vision for Sustainable Education
• The education experience incorporates the living
environment – a lifestyle education
• Active participation by all members of college-
faculty, students, staff, facility managers
• Transparency and targets for open
communication, discussion, and motivation
Building Environmental Awareness
• Installing an effective monitoring system
• Informing decision-making with the data
• Locate waste of resource
• Creating a low-carbon community
“Once it gets measured, it gets done!”
Chris Blencowe, Bursar of Pembroke College
The monitoring system
• Locate processes with high
energy consumption
=> Apply reusable current
clamps to track the sources of
high energy usage• Technological origin => technological
solution
• Behavioural origin => build
environmental awareness
• Continuously control critical
processes
=> Install stationary metering• i.e. air-conditioning etc.
Data analysis: informing decision-making

Environmental awareness campaign
• Spread the
word!Pembroke is a
„Green college‟ =>
Attract “Sustainable”
students
• Set up monitors in each
building showing energy
consumption
• Personalised feedback
to staff and students
A low carbon community
• “Green is cool”
• Enhancing current students and staff commitments
• Organise a “Green race”
• Attract
sponsors
• Regular
meeting of
the “Green
club”
Greening the Heat - Research
• Listed buildings!
• Gas = 6067 Mwh/yr
• Gas = 54% CO2 emissions
• For buildings and per person, gas is by far the largest consumed utility.
• At peak, 6/7 gas used for heating, 1/7 hot water
• Meet the English Heritage/CIBSE 4 aims for sustainable historic buildings.

Heat – what can be done?
• College provided branded blankets/sweaters
• Foil behind radiators
• Phase change materials
• Tri-Iso or vacuum thin room insulations
• Additional insulation of heat distribution and storage
• Thermal imaging/surveys
• Heat Technologies• Heat recovery systems
• Solar thermal
• Air source heat pumps
• Geothermal heat pumps
• CHP
• Radiant technologies
Geothermal Heat Pump
• 5kw/bore hole @ £5k
• One hole every 10m up to 100m deep
• 53 holes = 265kw @ £265k (1/4 load)
• Darwin College & Architecture have systems
• Water may not be hot enough for purpose
• Electricity needed for pumps
Inverter Combined Heat and Power
• Replace 1 boiler with 2 inverter-based 100kw CHPs that produce 250kw heat each @ £50k/engine (1/2 load)
• Peak electric use = 200kw+ = peak CHP production
• Modulate heat production based on use according to demand
• Possibility of excess electricity if use continues to decrease-ESCo opportunity?
• Gas dependence for life of boiler (~25 yrs)
New Radiant Technologies
• 90% efficiency for
electric heating
• „Warm edge‟ secondary
double glazing
• Room temperature
typically 2° cooler, or
12% reduction of power
• Single room controls
• Electricity dependent
