Sustainable energy solutions for Lidl distribution centre, Finland
The global supermarket chain Lidl has just opened its third distribution centre in Finland. The +60,000 m2 building is the size of 10 football fields and operates 100% on renewable energy.
Project DirectorT: +358 40 455 1130
Thermal energy and cold system design
The new distribution centre sets high standards for sustainable and smart energy solutions. Sustainable energy, construction and technology have been integrated in the project process and will be utilised throughout the lifecycle of the building.
Ramboll has played an important role in both project design and implementation. We have been responsible for the construction and control of the distribution centre and acted as environmental and energy consultant. Ramboll will also stay on as a consultant on the project during the operation stage of the building.
“It was important for us that Ramboll provides a high-quality expert organisation, which could contribute to the realisation of the project within a strict timeframe”, says Virpi Kaikkonen, Vice President for Real Estate and Development at Lidl.
- Construction management consultancy
- Site supervision
- BREEAM consulting
- Full thermal energy and cold system design
- Definition of the overall smart energy concept
- Ecological survey or the plot and surrounding areas prior to building and establishment of protection and improvement measures.
1,600 solar panels are installed on the roof of the building to generate electricity and heat through cogeneration. A significant part of the energy supplied to the local district heating network comes from the sun. Furthermore, excess condensate heat from the building’s cold system is likewise utilised for district heating.
With this two-way district heating connection, the building will end up having negative energy related emissions, as any excess energy is directed back to the local district heating network. As such, the solutions promote social, ecological and economical sustainability.
Moreover, the smart energy solutions comprise microgrid control of technical systems and optimisation of energy use, based on consumption data, weather forecasts and hourly priced energy supply. The building will also be connected to demand-response services with a 2.6MW electrical battery.
This is the first building in the world to combine microgrid control with the application of thermal energy optimisation and electrical side optimisation. It is also the first building to have both an MW-scale battery with connection to demand-response services together with a two-way district heating connection. All in all, a comprehensive solution like this has never been implemented in Finland before.
