12th IEA HEAT PUMP CONFERENCE 2017 Rotterdam 12TH IEA HEAT PUMP CONFERENCE WORLD TRADE CENTER ROTTERDAM 15 - 18 MAY 2017 ‘We’re from Rotterdam - we’ll keep going!’ appeared on a placard just days after by combining heat pumps with thermal the city was devastated by the WWII aerial bombings on 14 May 1940. This motto energy storage (ATES) in principal in many ways typifies the resolute character of Rotterdam and its inhabitants. In always in combination with district the war’s aftermath, a buzzing metropolis was built literally on the post-blitz ruins, heating. including a heating-network throughout the center. Sustainability is an important element In Rotterdam today, immigrants from over 170 different nations help create the city’s of Rotterdam’s vision. The thermal open and cosmopolitan atmosphere. The resolute perseverance of Rotterdam’s energy plan for the underground makes citizens still defines the city’s continual push for innovation at all levels of business, room for heat pump projects. Room for government and community life. innovation, but also literally: room to prevent interference between different Rotterdam is synonymous with innovation, whether it is in architecture, the creative sector thermal storage projects. or the port. Home to Europe’s largest port, Rotterdam is often a trendsetter. Just think of the Maasvlakte II project, extending the port into the sea, and of the architectural tours Rotterdam shows that having district de force in the Kop van Zuid district. heating does not exclude heat pumps nor energy storage, having this base The city on the Maas river is home to the offices of many of the world’s leading load opens opportunities. architects, including Rem Koolhaas’ OMA, the MVRDV and the ZUS. Rotterdam’s universities, educational institutes and knowledge centres, including the flagship Rotterdam strives for the optimal Erasmus University, have an international reputation for high-quality research and combination of different sustainable education. solutions, and the examples shown below prove that this approach works. Best practices Today’s Rotterdam is a young, multi-faceted and dynamic town. There is always something to experience in Rotterdam. It is a city that is booming and where the sky really is the limit. Rotterdam is also known for its vision for the future. The city centre of Rotterdam was completely rebuilt after the Second World War. ROTTERDAM Many new building projects fit the city’s commitment to strengthen its position both nationally and internationally in the 21st century. A MODERN A modern city with ambitious building projects also must have a heart for durable construction. The IEA honored that heart. In May of 2017, the 12th IEA Heat Pump CITY Conference will be held at the WTC conference hall in Rotterdam. So, how do heat WITH SUSTAINABLE BUILDINGS, pumps relate to the development of the city Rotterdam? Construction projects in Rotterdam demonstrate the very best practices of sustainable development, namely BUILT ON INNOVATION CASE: MARKTHAL 1. What is the project about? Situated in the heart of the center of Rotterdam just results of all these efforts. It shows the energy consumption of the building next to the current marketplace, the new Markthal and the resulting reduction of CO2 emissions in real time. provides space for a variety of functions.

In order to make this hall even every modern city center. more green, a passive, zero-energy ventilation system was also implemented. Outside air streams in at ground level and rises up to the roof, where fifteen chimneys function as exhaust piping. An information panel in the Martkhal displays the CASE: CENTRAL STATION 1. What is the project about? Central Station is fitted with the biggest solar panel roof ever to be found in a European train station. Of the roof’s 30,000 square meters, 10,000 square meters is covered in solar panels, an area larger than a football field. The solar power plant of 130,000 solar cells is expected to yield 340 MWh per year, which will provide ample energy supply for the escalators, lighting and elevators at the station. This is similar to the energy consumption of approximately 100 households. The sunroof achieves a CO2 reduction of about 8 percent. 2. What does the project include? • 10,000 square meters of solar panels, 340MWh per year • CO2 reduction of about 8 percent • Energy savings of about 30 percent for heating and cooling • Annual savings in CO2 compared to conventional sources of energy of about 20,000 kg • Average COP of free cooling and water- cooled machines of 7.2 compared to 3.5 for individual cooling • Complete renovation totaling 617 million euros 3. How are heat pumps integrated? Additionally, the station makes use of thermal storage. The shops and offices of the Rotterdam Central Station are connected to a thermal storage circuit and are kept warm and cool by the currents released from the station. Moreover, the cold and warm air are not only stored but also constantly reused. Three large frequency controled heat pumps are installed to cover the heat demand. 4. Why would you define this project a best-practice example? Rotterdam Central is expected to save about 30 percent on energy costs from this form of renewable geothermal energy. This will result in an annual savings in CO2 versus conventional sources of energy of about 20,000 kg. CASE: TIMMERHUIS AND BEURS/WTC 1. What is the project about? At the corner of the Think and Red Sand, Timmerhuis Rotterdam has been redeveloped into a multifunctional building with shops, restaurants, offices and homes. The new City Hall has also been built in this area. In paying tribute to the city’s history, the characteristic L-shaped Stadstimmerhuis from the 1950s is preserved and renovated. All construction work completed in the 1980s to the same area was demolished in 2009. In the new Timmerhuis Rotterdam complex, there will be a underground garage of approximately 120 parking spaces. The ground floor is accommodating shops and space for general use. Above the ground floor, 4 floors are dedicated to offices for commercial purposes. The remaining floors above composed of a mix of large and small apartments. In June 2011, the Board announced that it had decided not to move the Urban Centre of the City Hall to the Town Office. Part of the ground floor of the new City Hall was originally designated for the Urban XL. Demonstrating the flexibility of the space’s design, this space can now be filled in other ways, such as with restaurants or shops. Location of the 12th IEA Heat Pump Conference! 2. What does the project include? The building has 92 apartments with roof gardens and outdoor spaces. Construction of the Timmerhuis Rotterdam began in August 2012. 3. How are heat pumps integrated? At this project, they decided to use the so called cluster approach. Three ETP-Heat Pumps exchange heat and cold not only from the soil. The installation also uses two different buildings: Beurs/WTC and Timmerhuis as sources. Here a small smart cold net is created. In the near future also nearby buildings as the town hall and the shopping mall can be connected to this multifunctional heat-grid. 4. Why would you define this project a best-practice example? On one side, the builders had to deal with installations in a monument. Which is why strict rules apply on construction. The other side was that the new build construction is being done within a set steel prefab-cage. The plumbing had to go in between those steel pipes. It is a paradox to integrate the new and the old, yet mission was accomplished. No other building like this ever got the BREEAM Excellent**** certificate. CASE: MAASTOREN 1. What is the project about? With the construction of the Maastoren, the Rotterdam skyline gained a new icon. Erected in the Kop van Zuid area, the Maastoren has a height of 165 m, making it the tallest building in the Netherlands. Its floor space is ap- proximately 57,000 m², of which approximately 35,000 m² is reserved for office space, 17,000 m² for parking (both underground and street level), 4,000 m² is reserved for the entrance and facilities and 700 m² for technical space. 2. What does the project include? A practical but flexible and sustainable design within a strict budgetary framework: this was the design assignment that Techniplan Adviseurs received from OVG Projectontwik- keling for the Maastoren project in Rotterdam. Techniplan Adviseurs’ commitment to sustainable energy earned them the engineering award De Vernufteling in 2007. One of the most interesting aquifer thermal energy storage – is used to generate heating and cooling energy in the building as well as supply the sprinkler system.
