The Project
• To reduce CO2e year on year
• Baseline Energy Consumption 2,043MWh pa
• 2011/2012 Energy Consumption 1,669MWh pa
• Carbon Savings
- Base Year 251tCO2e
- Previous Year 111tCO2e
The Cost
• Recent Initiatives:
- Car park extract fans install CO2 detectors
Cost £14k Savings £21k pa
- Replace lights with new energy saving lights
Cost £6k Savings £3k pa
- Replace hand dryers with more energy efficient
Cost £20k Saving £10.5k pa
- = Return on investment 15 months
Unexpected Outcomes
• Easy quick wins
• No resistance from Finance Director
• Wish we had known about Smart Meters, ability
to obtain half hourly meter readings combined
with data from our sub meters.
• The tour !!

Achieved 14% reduction in CO2e between 2010 & 2011
Removal of 10 server boxes and making these virtual servers which has meant that they were using 5% energy of previous
Installation of about 18 PIR (passive infra-red) sensors for lights (@ less than £20 each) in common stair areas (working off movement and light)
Implementation of power saving
settings on all computers so that
monitors turn off after 10 minutes of
inactivity.

Server Virtualisation
Annual Energy saved =

Cost of traditional
replacement = £40000

Implementation of power saving

Implemented using MS SCCM –
acquired to roll-out new
applications to all computers – but
also provides central control of
power saving settings over our
internal network

Server Virtualisation
Positive – more space and less noise
Negative – not possible with all applications (i.e. Dongle licences)
PIR Sensors
Positive – adjustments available – light level and time on
Negative – gradual approach – not all at once
Computer Monitors
Positive – nobody complained!
Negative – actually not quite true – some engineers running long programmes
complained
We could have done some of this stuff earlier.
Unexpected outcomes and learning
Introduction
CODA Architects
• Medium sized Architectural practice
• Bristol Based, operating nationally
• Health, retail, Hospitality and education
• Projects from £100K to £100million
• Award Winning
• Collaborative and Ethical Approach
What was the project?
Coda Green Guide
• A Sustainable – in house, Design Guide
• Sharing our knowledge and plugging any gaps
Team Project involving:
• Workshops
• Individual study
• Presentations
• Discussions
What did it cost? What are the expected energy/carbon/cash savings?
Indirect Savings:
• Time - Efficiency of Design / work process
• The buildings we design are more energy efficient
• Our staff are more aware of Green Issues and therefore
more engaged in cutting carbon
Cost:
• Time
Were there any unexpected outcomes of this project? (both positive and negative)
Staff Engagement
• Better understanding of the issues and the need for change
• A willingness to accept other office wide initiatives
• Taking initiative and proposing better ways of working
What do you now wish you had known when you started?
• Keeping the information up to date is a challenge
• It hasn’t increased our ability to influence decisions as we had
hoped it would
We should have done it sooner

Energy Monitoring System
138 sensors throughout the building
Constantly recording energy usage of every
electrical appliance 24 hours a day
All data processing done in-house
An invaluable tool for reducing
consumption
Approx £8,500

Typical daily usage
Sustainability
Culture Change across the organisation
• Energy Reduction Group – 8 key staff
• Using energy data to make better use of the building, to
eliminate unnecessary usage and reduce necessary usage
• Improving departmental procedures, the way activities are
planned and the way spaces are used
• Introducing new duties for key departments and individuals
• Creating an environment where every member of staff is
constantly aware of the energy that they are using and
encouraging and enabling them to reduce it
