ACRONYM

1. Roman structure 2. Modern structure
- Reference to the Italian cultural origins
- Image of monumentality
- Recognizable spatial sign
THE ARCH As Architecture sign

THE ARCH

Solar panels Movable louvers
(to get sunlight in)
Movable panels
(to open-up the
solar chimney)
Green Roof
Green Wall
Specialized subfunctions
THE ARCH As Energy solution
- ventilation
- solar energy collection
- shielding
- insulation

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 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
Big patio (shaded by the arch)

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)
HOUSE BOX

Total surface: 60 m2
- Open space:
4 m x 10 m = 40 m2
- Bathroom:
2,3 m x 2 m = 4,6 m2
- Bedroom:
4 m x 2,3 m = 9,2 m2
- Engine room:
1,6 m x 2,8 m = 4,5 m2

SECURITY POWER MANAGEMENT
-Occupancy monitoring
-Window and door sensors alongside
-Cameras
-Motion detectors
-Glass break sensors
-User location
-App notifications
-911 connectivity
-Gesture control
-Voice commands
-Play music and movies
-Control volume levels
-Power balance tracking
-Heavy use identification
-Using certain devices at different times to improve
energy conservation
-Centralized HVAC system

DESIGN DEVELOPMENT

ARCH DEVELOPMENT
-”More open” Arch design
-Emphasis on engineering subfunctions

SOLAR CHIMNEY DEVELOPMENT
-Invisible design
-Emphasis on the contrast between the arch and the house box

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.

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
