ACRONYM
SOLAR DECATHLON 2015_STILE_Università degli Studi di Roma Tor Vergata & West Virginia University
1. Roman structure 2. Modern structure
- Reference to the Italian cultural origins
- Image of monumentality
- Recognizable spatial sign
SOLAR DECATHLON 2015_STILE_Università degli Studi di Roma Tor Vergata & West Virginia University
THE ARCH As Architecture sign
SOLAR DECATHLON 2015_STILE_Università degli Studi di Roma Tor Vergata & West Virginia University
THE ARCH
Solar panels Movable louvers
(to get sunlight in)
Movable panels
(to open-up the
solar chimney)
Green Roof
Green Wall
Specialized subfunctions
SOLAR DECATHLON 2015_STILE_Università degli Studi di Roma Tor Vergata & West Virginia University
THE ARCH As Energy solution
- ventilation
- solar energy collection
- shielding
- insulation
SOLAR DECATHLON 2015_STILE_Università degli Studi di Roma Tor Vergata & West Virginia University
SOLAR CHIMNEY
The density differences established
between the top and the bottom of the
building allows the air flowing into the
house, coming from north, west and east
openings
A solar chimney is a key element to ensure:
- The passive ventilation of the house
- The control of natural lighting
SOLAR DECATHLON 2015_STILE_Università degli Studi di Roma Tor Vergata & West Virginia University
SOLAR CHIMNEY
The simulation results showed a remarkable reduction of
the temperature in the house during a typical summer
day, by controlling the chimney opening
High conductivity material
ArchExtendable
Glass-walls

THE LINK BETWEEN THE ARCH AND THE HOUSE BOX
1. External view:
COMPACT BOX
2. Functional distribution:
2 DIFFERENT SECTIONS
Enclosed and functional
ambients
(walls toward North)
Open space
(glass-walls toward
South, East, West)

Simulations gave the following results:
-the chimney works well to cool the house down
during the hottest hours ( 9 – 18 ) exploiting the
high temperature of the exterior wall.
-the optimal number of air inlets is 3 for each wall
of the living room and 2 in the bedroom.
SOLAR DECATHLON 2015_STILE_Università degli Studi di Roma Tor Vergata & West Virginia University
SOLAR CHIMNEY DEVELOPMENT
Three differents cases were simulated:
-the house without the arch;
-the house with arch and panels;
-the house with totally covered arch.
Best results in the third configuration
Compromise between the second and
the third configuration by using brise
soleils on the arch
Practically unfeasible
