THINGS TO CONSIDER ABOUT

1.INTRODUCTION – ARCHITECURAL CHARACTERISTICS

The main building of the University of Athens :

designed by the Danish architect Hans Christian Hansen constructed between 1839 and 1842

Today :

headquarters of the University of Athens houses the offices of the Rectorate, the Juridical Department, the Archives and the Ceremonial Hall for official ceremonies refering to the University community.

6. IF THERE WAS MORE TIME.. – THINGS TO CONSIDER ABOUT

The Building :

Neoclassical style with a double T or H shape Two symmetrical courtyards Strictly symmetrical facade with an Ionian-style entrance Entrance emphasized by two heavy columns with impresive capitals, similar architecture to the Propylaea of AcropolisClassical fresco on the inner walls designed by the Bavarian Karl Rahl and painted after 1888 by Eduardo Lebiedzky

1. INTRODUCTION - ARCHITECTURAL CHARACTERISTIC OF THE BUILDING

The Exterior :

Five statues stand in front of the building, commemorating important figures of the modern Hellenic history (William E. Gladstone, Rigas Pheraios of Velestino, Gregorios V,Count, loannis Kapodistrias, Adamantios Korais).

Exterior consists of stone and green areas, formatting a circular entrance space. Two marble fountains at the front of the entrance complete the scene.

There also two paths that climb up sideways, at the front of the building.

2. CURRENT LIGHTING STATUS (Cont.)

* Actually, we saw no light nor water in the fountains!!

3. LIGHTING CONCEPT - DECISIONS

Aims and goals: Emphasize the functionality of the building ( a place for

learning, communication and intellectual exchanges).

Show the historical and cultural characteristics of building. Use the lighting to create an attractive atmosphere. Visitors are

invited to feel attracted and curious to explore. Emphasize the hug-shaped entrance.

Arrange the surroundings to create a friendly and calming place.

Emphasize the green space, highlight the fountains and the statues.

Finally: Playing with columns and fresco, giving the impression of a book that is ready to reveal its content but not without effort.

6. IF THERE WAS MORE TIME.. – THINGS TO CONSIDER ABOUT

• Examine different scenarios

• Examine lighting with respect to the two other buildings which consist Athens's Trilogy

• Full technical and economical analysis, regarding various different types of luminaires

• Exact photometric computations: how much lux needed and how much are finally delivered? (insert virtual surfaces in Relux)

• Regard mistakes done and have feedback

• Examine side views

• .. and maybe have a better presentation!

THANK YOU FOR YOUR ATTENTION!
