CO2 Emissions Reduction

Robert Stanley

Director Property and Facilities

27 September 2012

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 =

54 MWh (£5562)

Servers at end of useful life

(5 – 6 years)

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.

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

Sustainability

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
