1. GENERAL SCHEME

The strategy for the final energetic delivery follows the peculiarity of the site, using the geological charachteristics of the context through the soil, and at the same time exploiting the features of the building. The museum as piece of architecture but also as a machine which tryies to be as much efficient as possible, by specific systems designed in a total architectural integration point of view.

3. CASANOVA DATA

CASAnova is used for heating and cooling energy demand computation as well as the temperature behaviour in buildings can be used intuitively in order to understand the relations between building geometry, orientation, thermal insulation, glazing, solar heat gains, heating demand, heating and primary energy as well as overheating in summer. The calculation of heating demand is based on the European norm EN 832. The program calculates balance transmission and ventilation losses as well as solar and internal gains. Heating demand is the difference between energy losses and energy gains of the building.

Calculations are based on sampling ONE of the SEVENTYEIGHT (1/78) modules which compose the entire structure. (7,50 m x 15,00 m x 12,00 m height)
