1. Environmental Profiles Data Release: BRE Global’s proposed approach
Introduce yourself and what you do
Jane Anderson
BREEAM Materials, BRE Global
9th February 2010

2. Background Commitment to make LCA data available
Licensing of BBA to undertake Certified Environmental Profiles
Increasing numbers of industry tools based on ICE data, rather than cradle to grave LCA data from UK industry
Increasing requests from consultants to obtain data for use in internal tools
Requests from companies for data to “cross check” BRE Environmental Profiles and Green Guide with other LCA work
Integrity of Green Guide called into question
BRE need to increase functionality and understanding of data behind Green Guide Online

3. Approach Levels of Data Levels of Transparency
Levels of Confidentiality
Levels of Access
Levels of Knowledge
Validation of Users
Validation of Tools and Approach

4. Factory Data – annual production figures
Factory Data, eg.
Outputs:
21,539 tonnes
Inputs:
17,090 tonnes sand
5,209 tonnes cement
1,209 kWh Electricity
403 therms Natural Gas
Emissions:
179 g NMVOC
BRE will never make this data available to anyone, unless at your request

5. Factory data – per tonne Unit Process
Outputs:
1 tonne
Inputs:
0.793 tonnes sand
0.242 tonnes cement
kWh Electricity
therms Natural Gas
Emissions:
8.31 mg NMVOC

BRE will never make this data available to anyone, unless at your request

6. Factory data – per tonne System Process
Resources
Aluminium, 24% in bauxite, 11% in crude ore, in ground
in ground
2.7725E-08 kg
Anhydrite, in ground
5.2097E-12
Barite, 15% in crude ore, in ground
1.1424E-09
Basalt, in ground
1.4389E-10
Borax, in ground
6.8577E-12
Emissions to air
Acenaphthene
high. pop.
9.247E-15
Acetaldehyde
2.7931E-10
Acetic acid
2.2523E-10
2.379E-09
Acetone
2.2547E-10
low. pop.
1.6847E-10
Acrolein
1.1332E-13
2.079E-13
Actinides, radioactive, unspecified
4.8461E-10 Bq
Outputs:
1 tonne
Lists all resources and emissions to the system, cradle to gate
Normally about 300+ items
presentation
BRE will never make this data available to anyone, unless at your request

7. Factory Data
BRE will never publish or share any factory level data unless:
Manufacturer requests it
Data is Certified and used as a specific input to another product being modelled by another Environmental Profiles Provider – we will provide per tonne system process data

8. Generic data – per tonne Unit Process
Mass weighted Outputs:
1 tonne
Inputs:
0.769 tonnes sand
0.238 tonnes cement
kWh Electricity
therms Natural Gas
Emissions:
5.31 mg NMVOC
presentation
BRE will never make this data available to anyone, unless at TA request

9. Generic data – per tonne System Process
Outputs:
1 tonne
Resources:
0.8 tonnes sand and gravel extraction
0.315 tonnes limestone extraction
0.02 tonnes coal extraction
0.03 m3 Natural Gas extraction
7.3 litres surface water extraction
Emissions:
573 g Carbon dioxide
2.9 g methane
4 g NOx
10.3 mg NMVOC…
presentation
BRE have to make this data available to BBA and want to release to others

10. Generic data: System Process Data
BBA and any other Environmental Profiles Providers have to have access to your Generic Data for input materials
System Process data allows them to understand the causes of impact for input materials so that they can advise clients
BRE can ensure licence prevents use for any other purpose
Bath ICE data would need Carbon Dioxide and CO2 equivalent data for inclusion within their database, together with EPD report
Any other release:
only if Trade Association requests it

11. Generic data – per tonne characterised data
BRE want to use this data within BRE tools such as Green Guide, Envest, IMPACT etc
BRE want to release CC data to ICE (Bath)
BRE want to release this data to those who want access to LCA data for construction products for consultancy and in-house tools
BRE could manage requests and ensure cradle to grave LCA data is used
BRE could “validate” those wanting to use this data to ensure they understand LCA and how to use data correctly
BRE could “validate” internal and external tools
Payment would cover administration, validation and provision of other datasets, eg disposal, transport etc

12. Green Guide Online: Green Guide Expert
Green Guide Online: BRE want to provide breakdowns for listed specifications as a subscription service

13. Green Guide Online: Green Guide Expert
Green Guide Online: BRE want to provide breakdowns for listed specifications as a subscription service

14. Green Guide Online: Green Guide Expert
Green Guide Online: BRE want to provide breakdowns for listed specifications as a subscription service

15. Development of Green Guide Online
Green Guide Publication already provides
Embodied CO2
Service Life
Recycled Content (kg and % by mass)
Recycled currently at EOL (%)
Service will be subscription only
Annual Cost will be more than purchase cost of Green Guide publication
Cost covers BRE Costs to develop website and provide other data (transport, end of life, other datasets)
If significant profit then this will be discussed with the BRE Global Governance Board to consider future action (reinvestment in tools, reduced cost for profiles or reduced cost for access?)

16. IMPACT: TSB Design and Decision Tools Call
Basically Envest integrated with CAD models
Will provide Cradle to Grave Embodied data for whole building
IES undertaking software development for Phase 1
Links to Google SketchUp (early design)
Links to various CAD/BIM packages (detailed design)
Links to IES operational energy models
Overseas Versions using overseas databases
Delivery within 18 months
Phase 2: AEC3 – IFC compliant protocol for development of IMPACT by any other software developer/BIM package
Phase 2: Provision of IMPACT UK database for validated software

17. Certificated Environmental Profiles
Certificated data can be used in certificated Profiles where certificated input is used
BBA now licensed to undertake Certification of Environmental Profiles
BRE reviewing Cross Listing with other EPD schemes
European EPDs are mainly cradle to gate

18. Next Steps
BRE will be in contact with each Trade Association or manufacturer who have provided data
Letter will set out levels of data which
A: BRE have to release to operate the Environmental Profiles Certification Scheme
B: BRE want to release
BRE will give you the opportunity to opt out of release
In the absence permission for any level, BRE will:
Publish contact details for users to apply for permission
Discuss with you what alternative data we will use where we have to provide information
