A Sustainable vision for PembrokeEnergy supply:

Heat, electricity, waste to energy, biomassEnergy demand:

Laundry, insulation, windows, measuring and monitoring, smart controls, behavior change, lighting

Water:Grey water, rainwater, toilets, timers, temperatures, flow

restrictor, laundryWaste and Recycling:

Composting, sorting, audits, student swap scheme, behaviorManagement:

Oranization, rules, surveys, incentives

Greening the heating supply

If we can not insulate and reduce heating demand through envelope improvements, we can green the

heating supply

Current situation:

Heating is the primary energy user at Pembroke College

Technologies to examine

Solar thermalAir source heat pumps

Geothermal or Ground source heat pumps

Combined heat and power CHPNew Radiative technologies

Monitoring and metering: accounting for resource use

We can only optimise the environmental performance of Pembroke College if we

have sufficient knowledge of consumption

Current situation:

Monthly manual meter readings of the overall site

for gas and electricity

Aim:

Short interval, remotely read data with appropriate spacial granularity

For gas, electricity and water

Strategy:

1. Understanding the baseload and locating waste of resource

2. Informing decisions for resource management

3. Visualising consumption in an innovative way and providing feedback in order to

achieve behaviour-change

Positive potential:

Already motivated and concerned staff and students
