2. ZeroWIN Case Studies CS4 & CS7 Remade SE & Wilding Butler CS6 Bauserve CS5 & CS8 CEIFA Working with other ZeroWIN partners to conduct research Questions arising from the initial work carried out Stakeholder input required to decide way forward

3. Introduction Aim of the Case Studies Case studies 4, 5, 6 new buildings • Creation of stakeholders’ networks (producers of materials and components,owners or promoters, architects, contractors, waste management and energy experts) that allow the research team to monitor a sustainable construction project from the planning phase through to completion. Case studies 7 and 8 demolition • Research and development needed to assist businesses to correctly plan a demolition / construction project • Large volumes of potentially recyclable and re-usable materials being disposed of to landfill • Direct monitoring by the research team to provide information about waste types and volumes, logistics, available end markets and demolition protocols.

4. Workshop discussion Progress achieved – case studies started Challenges arising through the project Baseline scenario – how best to collect data? Main environmental impacts (CO2, waste, water) What opportunities for industrial symbiosis? Use of information on site – practical implementation of theoretical studies from WP3

5. Fit with the ZeroWIN Vision WP6 is the core of the ZeroWIN project: Targets • 30% reduction of greenhouse gas emissions • 70% overall re-use and recycling of waste • 75% reduction of fresh water use • Preparatory work will enable the nine industrial case studies that form WP6 • Aims to test the new production model under real-life conditions • Approaches can meet at least two of the targets above

6. Vision ideas from 06.07.10 Producer responsibility What is waste prevention Generate economies of scale through networks Competing demands for raw materials Changes in types of materials in manufacture affects end markets Corporate social responsibility – source of supply

7. Vision ideas from 06.07.10 Some material streams are transient e.g. CRTs Challenge old ways of thinking Where is the transformational shift? Are social networks of greater relevance in vision? Engage with more practitioners form other EU countries Enable business to get more involved – language?

8. DESIGN EXTRACTION OF RAW MATERIALS MATERIAL SUPPLIER MANUFACTURER RETAILER CONSUMER ZEROWIN SCOPE AND BOUNDARIES 5 MANUFACTURER COMPONENT SUPPLIER MATERIALS RECYCLING FACILITY RAW MATERIALS REFURBISHER RECYCLER UPSTREAM DISPOSAL??? Zero Waste – No disposal! • NOTES: • The manufacturers product the final product but also they origin waste materials / sub products that shall be considered (blue dotted arrows) • It was decided in the Bilbo meeting that there should not be a distinction between upstream and downstream cluster, seen as before and after the consumer. • In the next slides there is a suggestion for the appliance of this scheme to the construction sector (construction and demolition case-studies).

9. Case Study CS4Remade SE & Wilding Butler Network comprised of: Step By Step, Mixed Development, Aldershot, UK The Construction Team are as follows – Client- Sentinel Housing Association End User – Step by Step (SBS) Main Contractor – Wilding Butler Building Services Engineer- PJR Services Architectural Services- Re Format Structural Engineer – CSC Ltd Clients Representative – Madlin & Maddison

10. Monitoring of water, energy and waste Both energy and water use will be measured on site via meters from a local supplier. Wilding Butler partner with a recycling/waste disposal company who will provide data All suppliers and sub contractors will provide data for their works Wilding Butler will endeavour where possible to engage local suppliers within a given radius to minimise energy use. Wilding Butler will endeavour to negotiate a ‘take back’ scheme with local suppliers who, if surplus material is left after completion of each item will reuse/sell on to other contractors therefore reducing waste costs.

11. Progress to date Site clearance completed Foundations completed Ground slab completed Concrete frame ongoing Data collected so far; Fuel used by temporary generator Electricity used for temporary site offices and welfare facilities Water used, metered at site boundary Waste generated from current site operations

12. Case Study 7Remade SE Demolition of 11-13 Tontine Street, Folkestone, Kent, UK The Development Team are as follows – Client – Creative Foundations Architect – Jonathan Stuckey Architects Demolition Contractor – Yet to be appointed

14. Materials to be segregated on site Bricks Timber Metal General hardcore/concrete/bricks Roof tiles Plasterboard Glass Sanitaryware

15. Baseline scenario Demolition of Victorian school, Hythe, Kent, UK Bricks, 50% reused on site, 50% crushed for road base Wood, 25% reused, 75% incinerated (power from waste) Hardcore, 100% recycled on site Roof tiles, 100% reused on site Plasterboard, 100% recycled Glass, 100% recycled Sanitaryware, 100% reused

17. Mixed waste sent to a local waste transfer station 75% recycling rate (UK average 55%) Only 9 tonnes of waste sent to landfill Almost 900 tonnes of waste reused or recycled 99% reuse/recycling rate

21. Case Study 5 – CEIFAGoals Build stakeholders networks involved in a construction project and identify with them their perception of suitable best practices Identify in the construction site the processes suitable for intervention (great impacts and possibility to improvements), in order to promote industrial symbiosis  environmental gains consistent with the call targets For that it is necessary to establish a baseline scenario Identify economic opportunities and barriers to cooperative working within zero-win strategies

22. Case Study 5 – CEIFAEnvironmental Impacts and Baseline Scenario Building indicators for waste production, energy and water consumption (contacts with construction companies), in order to establish a proper baseline scenario according to the methodology defined (case specific baseline scenario)

23. Case Study 8 – CEIFAGoals Provide information on how the role of the planning phase for the reduction of environmental impacts of demolition Study the relative opportunities and barriers for reduction, reuse and recycling of secondary materials Highlight best practices and identify areas where improvements can be made Identify, in the selected site, the processes suitable for intervention (great impacts and possibility for improvements), in order to promote industrial symbiosis  environmental gains consistent with the call targets. For that it is necessary to establish a baseline scenario

24. Case Study 8 – CEIFAProgress Achieved Analysed Sites: Demolitions of two high schools (Portuguese Program for rehabilitation of high schools): Escola Secundária da Maia and Escola Secundária de Paços de Ferreira (both near to Oporto) Industrial Partner: General contractor – EDIFER (project stakeholder) Current stage of the CS: collection of demolition data for the baseline scenario, together with the involved actors identification of key processes and the networks involved identification of documentation failures A third demolition site will be added in the next months

25. Workshop Question 1 How relevant /useful is it to collect the following data? Energy (electricity) used within the site for: plant/machinery, lighting, site accommodation, small tools Fuel use for: plant/machinery Water use for: wheel-washing , site accommodation, wet trades, i.e. concrete CO2 Emissions from: transport movements to and from site, plant/machinery

26. Workshop Question 2 How would participating contractors undertake the minimisation of waste prior to commencement of site? Examples Selection of materials that produce less waste Selection of materials where waste arising is recyclable Careful management of materials to ensure that waste is minimised

27. Workshop Question 3 What standard metric should be used to measure the data required? Examples Per person employed on site? Per square metre of build area? Per Thousand Euro cost? Per tonne of material?

28. Workshop Question 4 What materials currently in use might be replaced by alternative products that have a high recycled content or produce less waste on site? Examples Wood replaced with recycled plastic products Brick replaced with proprietary cladding Roof tiles/slate replaced with green roofing

29. Workshop Question 5 What elements of sustainable procurement are considered when planning a site? Examples Materials and products with low embodied energy Materials and products containing high recycled content Materials and products that are recyclable at end of life

30. Workshop Question 6 Which aspects of energy and water consumption are stakeholders concerned about on site? Examples Reducing the amount of electricity used on site Reducing the amount of water used on site Considering alternative construction methods to avoid wet trades

31. Workshop Question 7 Where do stakeholders see the biggest savings in energy and water consumption on site? Examples Pre-manufactured products/pods Greater subcontractor involvement, i.e. to delegate entire areas of the construction Metering and controls on water and energy use

32. Question 8 What information shall we use to compare our measured results – baseline scenario? Country by country? Sector by sector? Standard construction site?
