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


IntroductionAim of the Case StudiesCase 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.


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


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


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


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?

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).


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


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.


Progress to date

• Site clearance completed• Foundations completed• Ground slab completed• Concrete frame ongoing

• Data collected so far;Fuel used by temporary generatorElectricity used for temporary site offices and welfare facilitiesWater used, metered at site boundaryWaste generated from current site operations


Case Study 7Remade SE

Demolition of 11-13 Tontine Street, Folkestone, Kent, UKThe Development Team are as follows –

• Client – Creative Foundations• Architect – Jonathan Stuckey Architects• Demolition Contractor – Yet to be appointed


Materials to be segregated on site

• Bricks• Timber• Metal• General hardcore/concrete/bricks• Roof tiles• Plasterboard• Glass• Sanitaryware


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


• 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

Case Study 5 – CEIFA Goals

• 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 targetsFor that it is necessary to establish a baseline scenario

• Identify economic opportunities and barriers to cooperative working within zero-win strategies


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)


Case Study 8 – CEIFA Goals

• 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


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


Workshop Question 1How relevant /useful is it to collect the following data?

Energy (electricity) used within the site for:• plant/machinery, lighting, site accommodation, small toolsFuel use for:• plant/machineryWater use for:• wheel-washing , site accommodation, wet trades, i.e.

concreteCO2 Emissions from:• transport movements to and from site, plant/machinery


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


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?


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


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


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


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


Question 8

• What information shall we use to compare our measured results – baseline scenario?
