31 Thermal storage In 2018 a permit was issued to Suitsupply 2Amsterdam and the new WTC tower to apply a thermal storage system. The permit allows for a maximum of two million cubic meters of ground water transport each year. This brings the total power output in Zuidas to 40 megawatt whereby 19 million cubic meters of ground water can be moved each year. The Zuidas Amsterdam Development Office formulated a Masterplan Thermal Storage for the sub-districts Ravel and Vivaldi. The plan will allow for new thermal storage initiatives to be applied in the future. The masterplan for the Kenniskwartier received an update this year to better fit the needs of the VU Amsterdam and the medical centre VUmc. Underneath the VU Amsterdam’s New University Building are two 160-metre-deep thermal storage wells. The wells were charged in 2018 for operating at capacity in 2019. After a year’s charge the system will work independently with incidental aid from above-ground installations at peak moments. Climate and lighting system Vesteda headquarters The De Boel building where Vesteda is headquartered has climate-control smart ceilings that heat and cool the offices. Smart ceilings work through heat irradiation and convection to make offices require less energy to operate at a comfortable temperature. Office lighting in De Boel consists of fluorescent and led lights. Most of the lights are triggered by sensors so the lights are only switched on when people are in the rooms. GVB invests in locally sourced green energy From 1 January 2019 Nuon/Vattenfall is the new energy supplier for Amsterdam city transport company GVB. This is the result of a tender that GVB issued together with Metro and Tram from the Municipality of Amsterdam in May 2018. The contract will run for ten years ending in December 2028. The green energy will all be produced nationally. In addition, Nuon/Vattenfall will increase their sustainable energy capacity in order to supply the GVB’s energy needs. Crowdfunded solar panels Nuon/Vattenfall crowdfunded bonds to take the first steps to develop three solar parks at existing electric power plants in Velsen, Eemshaven and Amsterdam. The full target investment of two million Euro was reached in less than two weeks after allowing Nuon customers and non-customers the opportunity to buy bonds in October 2018. The capacity is estimated at around 7.8 megawatt generated by 27 000 solar panels and will be enough to power 2500 households. Zuidas off the gas During Green Business Club Zuidas EnergieLab in October 2018 the ambition to get Zuidas off natural gas was launched. The Zuidas Amsterdam Development Office has already taken many steps to phase the area off gas. Together with Alliander they are mapping the energy needs for the area and the possibilities to use new techniques to optimise the energy network. Roland de Vlam, chairperson of Green Business Club Zuidas and lawyer at Loyens & Loeff wants to concentrate on getting existing buildings disconnected from the gas supply. VU Amsterdam and WTC have already started on this goal. Green Business Club Zuidas will develop a master plan with its participants to bring the ambition to fruition.
