Construction Industry

MAJOR sector of the national economy

8% of the UK GDP

Annual Output of £58 billion

But in environmental terms the…
Largest consumer of ALL resources of all
UK industries both directly and from its
supply chain of materials, producers,
fabricators and stockists.
Environmental Impacts

Approx 300 million tonnes of materials
extracted and quarried

72 million tonnes of construction/demolition
waste ( 17% of UK total)

40-50% of total UK emissions of CO2

Major consumer of energy ( buildings consume 49% of all energy in UK)

16% of water withdrawals

Approx 60% of all UK timber use – 25% virgin wood use – 90% of the 60%
imported

20% of all commercial and industrial noise complaints

Greatest number of water pollution incidents

Construction transport accounts for 13% of total UK fuel use and uses 4% of total
energy

Transport accounts for between 10-20% of total construction costs

Bill (2004)
– Code of Sustainable Building
Practices based on BREEAM
– The new code will establish
higher standards for energy and
water efficiency, as well as
waste and use of materials.
– Complete by the end of 2005, in
order to take action on a
national rollout by early 2006.

Edinburgh Vision- “to lead the most successful and
sustainable city region in northern Europe by 2015 and
sustain the highest quality of life of any UK city”
CEC Policy Drivers
 Standards
 Policy

Design Guide
Sustainable Design and Construction Policy Aim

The City of Edinburgh Council is committed to leading the
most sustainable northern-European city region by 2015.
The Council aims to integrate all the policy objectives into
our design and construction activities for all facilities and
buildings including refurbishment, new build, maintenance,
and decommissioning, irrespective of size. It shall be the
policy of the Council to aim to reduce the environmental
impacts from our buildings and ensure that natural
resources are used efficiently.
CEC Sustainable Design Guide
 Launched
 Assist
22 March 2005
in the implementation of the policy
 Training
being developed for Council staff and
external consultants/companies - modules to be
developed
 Roll
out of the policy across Council departments
Council Contracts for Construction

Incorporation of new clause in Council contracts (May
2005) that states:

The Council will expect the consultant appointed under this
contract to fully adopt the sustainable development aspirations of
the Council described in the Council documents “Towards a
Sustainable Council” , “The Sustainable Design and Construction
Policy” and the “Sustainable Design Guide”.

New CEC HQ
What was required from the developers?
“The City of Edinburgh Council is committed to sustainable
development in all new city centre building projects. The Office
Rationalisation Strategy provides an opportunity for the Council
to demonstrate this commitment and encourage the adoption of
sustainable development principles in the design of this project.
The selection board will be looking for evidence of a thorough
understanding of the issues with particular respect to the
environmental performance of the building, transport needs, the
working environment, maintenance and life cycle costs of the
building”
Taken from the Client Specification
Process

Unique approach involving developers, Council officers, design
team and sustainability consultants

Establishment of a Sustainability Working Group

Agreement of a set of sustainability criteria covering issues such
as energy, waste, water

Development of a series of targets to be met if appropriate or
feasible (exemplars)

Understanding the constraints in sustainability terms

PROCUREMENT PROCESS - absolutely crucial - also VERY
problemmatic
New CEC HQ Sustainability Key Performance
Indicators
There are 74 Sustainability KPI’s applying to ALL the stages of
the project: Design, Construction, Fit out and Operation.
These are incorporated into the Agreement for Lease
There are 14 categories of KPI’s:
Biodiversity
Management
Maintenance
Safety
Waste
Transport
Water
Materials
Pollution
Health and well being
Energy and C. Change
General
Social and Economic
Indoor Air Quality
Energy Efficiency & Climate Change KPI’s

 KPI

Materials KPI’s - some examples
•KPI 1.15
Timber - only use from certified
sustainable sources - preferably FSC
•KPI 1.16
PVC - use to be minimised
•KPI 1.24
Supply Chain Management Plan
•KPI 2.21
Use of recyclable materials
In practice - this is a very difficult area in construction to
address
KPI 1.15 - TIMBER
•Monitored in the construction phase - mixture to date of
FSC and PEFC timber
•Also applies to the fit out phase. Council contract went
out in Dec 2004 for its HQ furniture stipulated that :
•“companies have to have ISO 14001 Environmental
Management certification and Forest Stewardship
Council accreditation certificates (or equivalent) and
chain of custody certificates for all products. They had
to provide documentary evidence (that has been or
can be independently verified) to show that the
wood/wood product has originated from sustainably
managed resources.”
•TENDERS RETURNED WITHOUT THIS INFORMATION (OR
EQUIVALENT ) WILL NOT BE CONSIDERED

CASE STUDIES
 Schools
PPP2 ( 6) - set targets in the bidders
specification e.g carbon targets - kg/carbon (worked with
BRE), held meetings with potential bidders, worked up
sustainability requirements for insertion into contract spec
 New
Care Homes (4) - working with contractors -
feasibility studies for Biomass
 New
Civic Centre - set targets and use of workbook

BARRIERS

Procurement processes of the contractors particularly for
major projects but also smaller ones

Lack of knowledge of designers and contractors

Being too specific in setting KPI’s at the outset

Being too general in setting KPI’s at the outset

Difficulty in specifying local suppliers and contractors

Perception of cost vs sustainability options

Capital costs of some sustainability options - e.g New Care
Homes
LESSONS LEARNED

Devil is in the detail - need to have sustainability criteria in
contracts!!

Having a policy in place and ensuring that all relevant
Council officers are aware of it -

Importance of setting KPI’s (if that is the way a LA wants to
proceed) and having a process in place to allow this to
happen (or alternative)

Have expertise in house or seek it externally - from
consultants or other LA’s

Sustainability can save money!
