1 ecoflair ® A Case History: FARAM S.P.A. (PARMA, ITALY)

2 A significant example from a recent Italian newspaper (3 rd February 2010) Controversy over modern buildings: a recent case

3 The Council building is making us ill ! Deluge of complaints from employees about the new headquarters Some areas are freezing whereas others are boiling, encouraging illnesses The building was designed as an open space but was then subdivided Controversy over modern buildings: a recent case

17 Proposed Solution

18 Htwh – Heat transfer unit Modular access floor INSTALLATION SCHEME Supervisory system Unitile – Terminal units ecoflair ® - Integrated solution patented by Uniflair Energy Provider - Multifunctional unit Accv – Air Handling unit

19 14°C 35°C Cold and Hot Loop Heating and cooling simultaneously Water based (no refrigerant indoors) Water Temp. : 14°C cold / 35°C hot high comfort energy saving (high C.O.P.) compatibility with alternative energy sources (geothermic, solar,..) Separation of sensible/latent load

20 Coil + fan: allows cooling or heating of the area in which it is installed Modular dimensions (600x600 mm): for integrated installation in a raised floor Connected with flexible pipes, these units can be moved according to layout changes Unitile – Terminal unit 230 mm 600 mm

21 (*) Designed with the Physics Department, Architecture University of Venice Directional grille (*) The discharge grille directs the air-flow to follow a “bell” path, creating a sort of “climatic bubble” between the Unitile and the suction grille. The air-speed is reduced in order to obtain a high level of comfort for users.

22 To connect Unitiles to the main pipes Increasing flexibility: with a local pump and “plug and play” connections, it allows to move and to add Unitile units, increasing the cooling capacity. Simplicity and speed of installation Hydraulic Kit

27 Commercial buildings often require heating and cooling simultaneously during the year Transferring energy is much better rather than creating it: this is the basic idea of the ecoflair ® system The Heat Transfer Unit (HTWH) balances the simultaneous opposite thermal loads within the building Energy efficiency

28 Commercial buildings often require heating and cooling simultaneously during the year Transferring energy is much better rather than creating it: this is the basic idea of the ecoflair ® system The Heat Transfer Unit (HTWH) balances the simultaneous opposite thermal loads within the building Energy efficiency

29 Cooling: some heat is “removed” from the air, and it is transferred to the cold loop (water T. increases) In the HTWH this q.ty of heat is “moved” from the cold to the hot water Heating: the heat which has been cumulated in the hot loop (water) is given back to the air in another building area Heat Transfer Unit - HTWH Restores the water set-point temperature in the 2 loops, transferring excess energy from the cold to the hot loop

30 HEATING LOAD (kW) COOLING LOAD (kW) TRANSFERRED BY THE HTWH TRANSFERRED BY THE HTWH PROVIDED BY THE E.P. PROVIDED BY THE E.P. Energy Provider - external multifunctional unit Integrates the unbalanced thermal energy Production of hot and cold water independently or simultaneously Independent cold/hot water circuits (no cycle inversion) Reduced footprint (1 unit only) Free-cooling operation available High energy efficiency (recovering heat) Outdoor and easy installation

31 Managing the quality of internal air: Humidity (humidification/dehumidification) Adequate air exchange Air filtration Monitoring of the CO 2 and VOC levels Cross flow heat exchanger to exchange heat between exhausted discharged air and incoming fresh air. ACCV – Air handling unit
