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

Proposed Solution
17
ecoflair® - Integrated solution patented by Uniflair
Unitile – Terminal units
Htwh – Heat transfer unit
Energy Provider - Multifunctional unit
Accv – Air Handling unit
Modular access floor
INSTALLATION SCHEME
Supervisory system
18
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, ..)
14°C
35°C
Separation of sensible/latent load
19
Unitile – Terminal unit
• 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
230 mm
changes
20
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.
(*) Designed with the Physics Department, Architecture University of Venice
21
Hydraulic Kit
• 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

23
Local User Terminal
• User setting for temperature and airspeed (1,2,3, auto)
• Stand-alone operation
• Integrated ambient temperature sensor
Wall installation
• Easy connection in TLan with Utat units
TLan
Table support installation
24
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
25
Energy efficiency
• 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
• 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
28
Heat Transfer Unit - HTWH
• Restores the water set-point temperature in the 2 loops, transferring excess
energy from the cold to the hot loop
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
29
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)
COOLING LOAD
(kW)
HEATING LOAD
(kW)
• Reduced footprint (1 unit only)
• Free-cooling operation available
TRANSFERRED
BY THE HTWH
• High energy efficiency (recovering heat)
• Outdoor and easy installation
PROVIDED BY
THE E.P.
30
ACCV – Air handling unit
• 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.
