A Case History:
FARAM S.P.A. (PARMA , ITALY)
2
A significant example from
a recent Italian newspaper
(3rd 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

Proposed Solution

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

14°C35°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

(*) 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

• User setting for temperature and air-
speed (1,2,3, auto)
• Stand-alone operation
• Integrated ambient temperature sensor
• Easy connection in TLan with Utat units

Wireless control
• Advanced technology
• Simplicity and speed of installation
• Reduced cost of installation
• Increasing flexibility in moving Unitiles
• Captivating design
• No visible wires on desks
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

Cooling: some heat is
“removed” from the air, and
it is transferred to the cold
loop (water T. increases)
Cooling: some heat is

heat is “moved” from the
cold to the hot water
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

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 CO2 and VOC levels
• Cross flow heat exchanger to exchange
heat between exhausted discharged air and
incoming fresh air.
