Office building “36-The Calls" Arch.Flavio Cucina
The building is composed of six levels and mainly used for the office spaces ;quality of natural illumination, energy saving, traditional materials and reasonable low costs are the guideline of the project .
Steel for the main structure and wood for part of the flooring as in the local use are the main materials; terracotta brise soleil are also well integrated with the surrounding docks realized in bricks .
At level 1 to 4 there are open space offices and all the services are located at the western side in order to better capture the light inside the offices . Apart from the main staircase located next to the elevator , there is a second open staircase connecting all levels with a vertical cut from the sky light to the ground floor and bringing additional natural light into the building . A conference room oriented towards south is located on each of the floors .
Roof plan contains the sky light as well as the system to collect the solar energy .
"Climate energy concept" M.Arch.Jochen Stopper
Facade: Thermal optimized facade with reduced transmission losses. Windows with U-Value 0.4 W/m ² K and opaque breast with U-Value 0.15 W/m ² K.
Shading and Photovoltaic: Optimized Photovoltaic (slope: 37°, south; ca. 3300 kWh/a) as shading device and renewable energy source. Electricity used for operating heat pump. Additional shading devices for summer sunlight. Indirect sunlight (north) as daylight source.
Heating: Ground water heat pump using river as renewable energy source. Amount of Electricity from Photovoltaic. Floor heating.
Ventilation: Mechanical ventilation with heat exchanger (CO 2 less than 1500 ppm guaranteed). Approximately 85% of the indoor temperature will be recovered and used to heat up the fresh air (approximately 30 – 50% energy saving potential).
