1 5.3 Sustainability Central Plant nergy that is currently rejected to the atmosphere will be recovered. The existing TLUS facility contains a considerable amount of electrical equipment for telecommunications, which along with lighting, computers and people produces a tremendous amount of heat. The mechanical systems in response to this load, rejects heat to cool. Most of this surplus energy is currently rejected to the atmosphere. TLUS Garden proposes to harness this surplus energy in a Central Plant by sharing energy not only between the new and existing buildings, but between the different uses office and residential. There is also the opportunity to enhance the system by using geo-exchange as a heat source in the winter and a heat sink in the summer. Located in the new Office lobby, the Central Plant will be visible and a didactic testament to TLUS Garden s committment to a sustainable future. 48 H N R I Q U Z P R T N R S

2 TLUS Garden New Residential Tower New Office Tower The existing TLUS uilding has a condenser loop that transfers the condenser water (heat rejection cycle) from the Chillers or cooling plant to the Fluid Cooler that rejects heat to the atmosphere. y tapping into the existing risers with new supply and return pipes, we will direct that condenser water towards the new heat exchanger and recover that energy to pre-heat domestic cold water or use that heat in the condenser water loop of the residential tower to generate low grade heating energy. Visible Central Plant Heat Rejection verywhere in the world, the earth s surface under the frost line maintains a nearly constant temperature between 10 C and 16 C (50 F and 60 F), remaining warmer than the air above it in the winter and cooler in the summer. geo-exchange system takes advantage of this constant temperature by transferring heat stored in the earth into a building during the winter and transferring it out of the building and back into the ground during the summer. The ground acts as a heat source in winter and a heat sink in summer. Geo-xchange xisting TLUS Facility 49
