Heating and Cooling Strategy

My design employs three systems for maintaining a desired and stable internal temperature. The first utilises the thermal mass of the concrete floor slabs to help ruglate the buildings internal temperature. The sun, heats the floors slabs throughout the day, made possible by the large expanses of glass. At night this is radiated back into the spaces, creating more stable internal environments throughout the year.

The second is an Open loop Water Source Heat Pump, this genreates heat from the River Seine, by using the small amount of embodied solar heat within the water which, under intense compression yields heat suitable to maintain the building . This system, uses minimal electrical power and no waste products. This system is more reliable than ground source heat pumps, because the temperature os water varies less on average than the ground or air, fluctuating generally between 7 to 12 degrees year round.

Finally a heat recovery system will be installed at each of the exhaust air vents on the service towers. This uses the waste heat generated by the buildings inhabitants to heat fluid that can then be returned to the buildings radiators. Insuring that energy waste within the building is minimised

Heating Services distributed via similar mean s as ventilation. However all heating elements pass first through the ground floor plant room . For the atrium, heating pipes pass under the floor, due the height of the space and lack of a consistent ceiling.

The structural strategy of the building was one of the primary design focal points. The structure intends to mix a highly regimented steel scaffold like frame that relies on vertical supporting columns, with interior spaces that, to make them as flexible as possible have no internal columns at all. These volumes sit within the scaffold frame, but apart from four linking bridges, never touch it. Part of the scaffold frame is enclosed by glass walls and a single span roof, so that people can inhabit not only the interiors of the volumes but also under and on top of them.

Roof slab, like volume floors and roof, performs a non-essential bracing role

Warren truss steel roof supports brace the outer scaffold frame.

Reinforced concrete slabs provide bracing function for volumes, but in this system, are not essential to the buildings structural integrity, and are installed after the frame is constructed
