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
