10. CO2 Emissions Reduction
Robert Stanley
Director Property and Facilities
27 September 2012

11. 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

12. 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

13. 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 !!

15. Buro Happold
Camden Mill, Bath (400 staff)
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.

16. Buro Happold
Server Virtualisation
Server Virtualisation
 Annual Energy saved =
54 MWh (£5562)
 Servers at end of useful life
(5 – 6 years)
 Cost of traditional
replacement = £40000
(Capital cost and
maintenance)
 Actual cost of server
virtualisation = £16000
(Capital Cost &
maintenance)

17. Buro Happold
PIR Motion and Daylight sensors
PIR Motion and Daylight
sensors
 Annual Energy saved = 4 MWh
(£400)
 Installation of about 18 PIR
(passive infra-red) sensors for
lights in common stair areas
(working off movement and
light)
 Cost = £36 per PIR (£18 plus
installation)

18. Buro Happold
Power Saving Settings on Monitors
Power Saving Settings on
Computer Monitors
 Annual Energy Saving = 5-6 MWh
(£600)
 Implementation of power saving
settings on all computers so that
monitors turn off after 10 minutes
of inactivity.
 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

19. Buro Happold
Unexpected outcomes and learning
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.

21. 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

22. 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

23. What did it cost?
What are the expected energy/carbon/cash savings?
Cost:
• Time
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

24. 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

25. 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

26. Sustainability

27. 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
Sustainability

28. Typical daily usage
Sustainability

29. 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

31. The next step in energy reduction:
Our 50 kWp photovoltaic array
Large enough to power 11
households
Providing 3.2% of our annual
electricity use
Meeting 20% of the building’s
needs at peak performance
Saving 25 tonnes of CO2 per
year
Currently performing 7.5%
above predictions
Funding grant from EDF
