The stages of the BREEAM assessment

• Covers:• New build• Major refurbishments, i.e. building works that would significantly

change the environmental performance of the building, like changing the windows, substituting part of the fabric, adding insulation, changing the services

• Extensions• Existing buildings in operation

Any questions?

Management

• Effective Building Operation

– Commissioning– Construction Impacts– User Guide– Life Cycle Analysis– Publication of Building Information– Shared Facilities– Development as a Learning Resource– Maintenance– Consultation– Security

Health and Wellbeing

• Indoor Environment– View out– Thermal Comfort– Natural and Artificial Lighting– Air Quality – Acoustics– Microbial Contamination– Drinking Water

• Occupant Control

• Occupant Satisfaction

Energy• Reducing CO2 Emissions

– NCM’s kgCO2/m2 calculation• Activity• Geometry• Construction / Materials • HVAC systems• Hot water• Artificial / natural lighting • Renewable energy sources

– Improvement above Part L2 of Building Regs– Linked with EPBD and DEC

• Sub-metering of energy

• External lighting

Transport

• Reducing CO2 Emissions from travel

– Access to Public Transport – Cycling Facilities – Pedestrian and cyclist safety– Green Travel Plan

Water

• Reducing Water Consumption

– Low water consumption fittings– Water recycling– Metering– Leak detection – Maintenance

Materials

• Reducing Material Use– Reuse of Structure / Façade– Designing for Robustness

• Reducing the Impact of Materials– Timber/Glass/Concrete/Insulation…– Key Building Elements

Waste

• Recyclable Waste– Storage recyclable waste– Aggregates / Construction Waste

Land Use and Ecology

• Brownfield / Contaminated Land

– Reuse of land

• Ecology– Ecological enhancement – Ecological value– Local Wildlife Partnerships– Consultation with Students and Staff

• Protection of Ecological Features

– Long term impact

Pollution

• Minimising Harmful Pollutants

– Refrigerants– Insulation– NOx Emissions

– Renewable and low CO2 Emission Energy Sources

– Flood risk – Watercourse Pollution– Night Light Pollution

How do you get the higher BREEAM ratings?

• Early• Forward planning• Know BREEAM• Build relationships• Capitalise on project

opportunities– Cost effective credits– Consider weighting

• Takes time• Pre-Assessment Estimator

BREEAM

The price of sustainable schools

• BRE and Faithful+Gould – funded by BRE Trust and DCSF

• Information Paper IP 1/08: ‘The price of sustainable schools: how much does it cost to achieve BREEAM schools ratings?’

• Summary of the capital cost implications of achieving BREEAM Schools ratings and low/zero carbon for:

– Primary school– Secondary school

• IP now available from BRE bookshop £9 www.bre.co.uk/brebookshop

Summary of results

Pass Good Very Good Excellent Zero/low carbon

Primary school

0 – 0.2 0.5 – 0.8 1.4 – 2.5 4.5 – 7.6 2.1 – 9.8

Secondary school

0 – 0.1 0.2 – 0.7 1.0 – 2.6 4.1 – 5.6 2.7 – 15.3

• Percentage increase in capital cost to achieve a BREEAM Schools rating:

Putting a price on sustainable schools

• Publication FB15: ‘Putting a Price on Sustainable Schools’

• Detailed outline of capital cost per BREEAM Schools credit and cost of low/zero carbon solutions for two case studies:

– Primary school– Secondary school

• Available April 2008

Any questions?

Scope of BREEAM FE

• All further education / adult / vocational colleges, standalone sixth form buildings and 14-19 schools with vocational facilities.

• The LSC has stated: ‘To qualify for LSC capital funds all proposals will need to address Sustainable Development by ensuring that the completed development meets the criteria to achieve 'Very Good' Building Research Establishment Environmental Assessment Method (BREEAM) rating.‘

Further Education Tool

Function AreasCredit Criteria

Applicability of the credits: whole site / function area

BREEAM update 2008

• From May ‘08, BREEAM Schools and BREEAM FE will be incorporated in one scheme, BREEAM Education

• Filtered credits• One assessment tool / one manual • This might also include BREEAM HE – when developed

PembrokeshireCollege

BREEAM – Bespoke Assessments

• Area weighted– Whole building credits are most valuable and offer best value– Specific ‘Area’ credits can often be of low value– FMSDG identified the ‘best value’ credits to be targeted

– Now to be BREEAM FE – semi Bespoke – still area weighted

BREEAM – The important bit

• Every credit must be robustly evidenced before it can be awarded

• Design Team & Client responsible for providing evidence for all credits to be pursued

• Pembrokeshire College evidenced in 3 weeks!

Excellent Wasn’t easy!

• 100% of credits weren’t available• Several site related BREEAM credits not

fully achievable– Transport Links – didn’t fit the BREEAM mould– Ecology – not contaminated!

• Some BREEAM credits not available due to the design/specification

– Re-used Facades & Structures– Pollution (NOx)

Pembrokeshire College – How Excellent was achieved

Highly sustainable basic design• Low energy use and renewables• Water efficient• Re-use of land• Good location• Good contractor

Additional Requirements• Ecology• Further water efficiencies• Transport

facilities

Green Strategy – Breeam Wins Construction Technology Centre

• Water Section:- Low Flush Toilets- Waterless Urinals- Rainwater Harvesting- Passive Infra Red detection on taps- Solenoid valve shut off to WC’s not in use- Minimal Irrigation of plants- Water metering- Leak detection

• Energy:- 29% Total Building Energy supplied by biomass (renewable energy source)- 3% Total Building Energy supplied by Solar Thermal System- BMS controls thermal zoning for varying occupancies

• Management:- Registered with CCS- Building User Guide- Pre seasonal specialist commissioning- key stakeholder consultation
