Area
environmental parameters of the area to minimize energy demand and provide comfortable internal conditions. The overall project is totally compatible with the initial targets and the area’s restrictions. We are called to design for a 4-member family (a young couple with two little children, a girl and a boy) who have decided to move from the center of the city to their new house at the South-East suburbs of Washington in order to raise the children in a more pleasant environment. The desired conditions in the spaces were carefully defined according to Ashrae 55 guide. Both PMV and Adaptive models were used where applicable.

THEATRE IN LONDON
U.C.L. EDE Natural and Mechanical Ventilation Project Supervisor: Dejan Mumovic Design Team : Andreas Alygizos / Georgios Koronaios/ Feng Yifu / Kontopoulou Vasiliki Location : London/Uk Dec 2014
ABSTR ACT: Aim of this particular project is to introduce the fundamental principles of passive thermal and ventilation design during the design process of a new building. The principles implemented should adapt and reinforce the architectural synthesis into a united complex. The building is a theatre and is open to everyone so this public character is revealed throughout its design. Except from the auditorium space where scheduled performances are being held, the building also includes a cafe and a reception space which complements its character. The main entrance of the building leads to the reception space from where there is the access to the rest of the building. In the same space a box office is located, where people can buy tickets for the

ABSTR ACT: The subject of the diploma project, is located in Chania, a provincial city on the island of Crete, at the south of Greece and puprose of the project is to reestablish the spatial relation between the current city with its Venetian walls that were build in the 14th century.The Venetian walls and the moat surrounds them constitutes a very strong edge over the city’s urban grid. The place of interest is the east side of the walls where the problems are more intense. The total site has split into three parts, the main side of the walls and the two corner sites of the bastions. Through the design approach is suggested a solution that makes the people reconsider their past through the memory carried through the walls, and establish a new way of confronting that historical site, while connects again the separate parts, creating so a unified complex.

ΤOURIST INFORMATION DESK
Architectural Student Competition May /2012 Design Team : Andreas Alygizos,Georgios Koronaios Chania_Crete
A B S T R AC T The subject of the competition was the design of an information pavilion for the city of Chania , which will be used for giving advices to the tourists visiting the city during the summer months. The proposed pavilion, has the size of 4 sq ,and can be placed in several spots in the urban area. The structural framework is made of metal, and is being constructed in the factory, and it is covered with surfaces made of PVC of glass. The pavilion is being transported to the site of interest and is being assembled on the spot. During the operating hours, the construction opens, and splits in two parts, an external one, where people can have free access to the digital material about the city and the weather, and an internal one, where tourists can be informed by the working staff directly. Moreover, there are places for printed materials, both inside and outside as well as two screen projectors on both sides of the pavilion, which function all day long, showing useful information about the city’s sites of interest.
