  2. 2. Plaza Loiste Key Facts • 7 240 m² office space • 6 office floors, of which 2 for Uponor • First BREEAM Very Good certified office complex in Finland • Energy Class A • UFHC, ceiling cooling, ground energy • Architect: Forma-Futura Oy • Developer: NCC Property Development • HVAC design: Optiplan Oy, Uponor 25 November 2013 ©Uponor 2
  3. 3. VENTILATION MACHINERY ROOM • Mechanical supply/ exhaust with high efficiency heat recovery • Water chillers for peak cooling demand UPONOR FLOORS • Underfloor heating and cooling with free cooling from boreholes • Ceiling cooling for peak demand • Air circulation chillers for peak demand in meeting rooms ENTRANCE AREA Snow and ice melting • BOILER ROOM • Connections to district heating and boreholes FREE COOLING 11 boreholes with Uponor G12 providing free cooling to Uponor floors 25 November 2013 FLOORS 1 - 5 Underfloor heating ©Uponor 3
  4. 4. 25 November 2013 ©Uponor 4
  5. 5. Plaza Loiste Environmental Performance Free cooling for energy efficiency Energy production of the Plaza Loiste borehole cooling system Month • Free cooling energy from the boreholes covers the cooling demand of the Uponor offices • Purchased cooling energy need eliminated on an annual basis • Monitoring program established from the cooling season 2014 onwards Simulated energy production of the borehole field Cooling energy demand of the building kWh/month Anna Forsström: G-12 ENERGIANKERUUPUTKIEN KÄYTTÖ MAAVIILEÄN KERUUSSA Opinnäytetyö, Ympäristöteknologia, YAMK ,Toukokuu 2013 25 November 2013 ©Uponor 5
  6. 6. Plaza Loiste occupant survey Thermal environment and sensation • High satisfaction level, with some remarks on too cold temperature levels especially in the meeting rooms • Regulation of the meeting room fan coil units has been adjusted after the summer period, and they should now work appropriately during the next cooling season 25 November 2013 ©Uponor 6
