THE SEARCH FOR WASTE HEAT FROM BUSINESS PARKS FOR HOUSING Eveline Huyghe WVI www.wvi.be BARON RUZETTELAAN 35 8310 BRUGGE T +32 50 36 71 71 E [email protected] THE SEARCH FOR WASTE HEAT FROM A BUSINESS PARK FOR HOUSING - who is WVI? - history of the sugar factory - location Veurne and site - masterplan - energy study - availability of heat - need for heat - technical design - financial feasbility - conclusions WHO IS WVI? Who is WVI? • intermunicipal association for regional development • service rendering association • owner and developer of the former sugar factory site Working area • 54 municipalities in the regions Westhoek, Ostend-Bruges, Roeselare-Tielt • 930 000 inhabitants Competencies • realisation and management of business parks • Realisation of housing projects • Spatial and mobility planning • Advice concerning environment, nature, energy & climate • Project direction HISTORY OF THE SUGAR FACTORY 1924: °sugar factory Veurne in art deco (arch. C. Van Eslande), first sugar beet campaign (700 tons/day) by railway, tramway, ship 1960: until 1 800 tons sugar beets/day by truck, seasonal employment of about 200 people – decline of railway station area December 2005: sugar factory closes 2006: land purchase negotiations + demolition of buildings & silos December 2006: WVI buys the land (excl. site Dreamland) 2009-2011: masterplan design by in cooperation with Veurne & WVI communication and particpation with inhabitants 2011-2012: design and approval of the formal spatial plan public investigation: information market for inhabitants 2012: project advice sustainable town extensions (PADD) LOCATION MASTERPLAN the site, 48 hectare MASTERPLAN HOUSING • • • • • number of planned dwellings: ca. 450 (13.5 ha) proportion apartments – single family dwellings: about 60/40 all dwellings are connected/houses in the row usable floor space houses = 210m², apartment = 120m² density 25 dwellings/hectare MASTERPLAN BUSINESS PARK BUSINESS PARK - 8,6 hectare - +/- 14 buildings with a floor space of average 7.000m² - New to develop business park borders the existing business park Veurne I - reserved for companies how need > 5.000 m² ENERGY STUDY AIM appoint a consultant to execute a feasibility study for a sustainable location fixed energy supply in the form of a heat network, investigating the market conformity and technical & financial aspects for the project Sugar Factory in Veurne. ENERGY STUDY VISION • WVI considers this project a unique opportunity for a heat network the availability of waste heat is an added value! • important questions: • What about the market conformity of a collective heating systems? • What is the profitabililty for the different stakeholders: producers of heat/waste heat, purchasers, grid operators, suppliers? ENERGY STUDY ASSIGNMENT part 1: part 2: part 3: part 4: inventory, heat supply and demand market conformity and simple technical/financial feasibility study detailed technical study (optional) detailed financial study (optional) HEAT SUPPLY EXISTING BUSINESS PARK • Pepsico • investigates internal re-use of heat • 500 kW per fryer (2 units), 40°C Too much uncertainty to consider Pepsico as a supplier • Trotec • treatment of unused food products • re-use from process gas, 300 kW, max. 80°C • week regime of 5 days/week continuous, increasingly regarded as supplier of waste heat in the feasibility study HEAT DEMAND EXISTING BUSINESS PARK • limited reaction on the survey 18% • a lot of logistic companies • biggest heat demand with Baronie and Meli (chocolates and honey) • inventorised heat demand based on the survey = 4.920 MWh HEAT DEMAND NEW DWELLINGS • assumption of heat demand for heating and hot water • total heat demand HEAT DEMAND NEW BUSINESS PARK • assumption heat demand for heating • total heat demand HEAT DEMAND DEMARCATION OF THE REGARDED AREA • guaranteed heat demand is needed for the realisation of a heat network • the new to develop housing area on the sugar factory site gives this guarantee when no gas network is implemented. • the heat demand of the new to develop and existing business park is not guaranteed only the housing zone is further regarded in the feasibility study TECHNICAL DESIGN: HEAT NETWORK ROUTE TECHNICAL DESIGN: HEAT PRODUCTION FINANCIAL FEASIBILITY: RESULTS CONCLUSIONS • large scaled project with guaranteed reasonable heat demand • heat supply from waste heat is preferred • current concept using waste heat is financial feasible with some optimisations • • • • • implementation of a boiler house construction heat network at the same time as other utilities investment support higher contribution as avoided cost for renewable energy assumption of heat demand • phased development, currently 2 phases
