The glass facades of the building capture daylight and limit solar gain through a series of horizontal and vertical shading devices that provide dynamic perspectives of the building when it is viewed from different angles.
Australian Antarctic Division director Kim Ellis said the special mounting of the panels would strike a balance between maximum solar gain and stability in the wind, as well as ensuring the panels were easy to install, access and maintain.
"The tower's cylindrical form opens like a shell to the north to avoid solar gain, while revealing views of the Arabian Gulf.
These active facades include such things as automatic solar shading to reduce solar gain, screens which automatically close at night to maximise insulation and automatic natural ventilation systems to purge stale air.
The sensible capacity of a radiant floor is 12-14 Btu/h.[ft.sup.2] (38-44 Watts/[meters.sup.2]) and this capacity can double if the floor is receiving direct solar gain, as shown in Figure 4-C.
Lidl said: "The fully glassfronted facade maximises natural daylight entering the building, whilst sensor controlled exterior sun blinds automatically operate to mitigate the effects of unwanted heat from solar gain.
The images depict the museum's 7,000-tonne dome covered in steel latticework, which will house its gallery spaces as well as acting as a micro-climate without excess solar gain.
There are also a number of energy efficient fittings, including: | A glass-fronted facade maximising natural daylight entering the building | Sensor-controlled exterior sun blinds automatically operating to mitigate the effects of unwanted heat from solar gain | An electrical lighting system made up entirely of LED fittings which, compared with a traditional lighting system, are over 50% more energy efficient whilst still providing good levels of lighting.
The new applied film technology used in the field test provides both solar gain control and thermal insulation thanks to an additional low-E surface that faces into the room.
And in winter, they ensure solar gain. So that no matter what the season, people inside stay comfortable at all times.
It addresses the energy problem; what is needed for human comfort; heat losses from a structure; materials used in residential construction and construction techniques; the seasons and solar angles; the transmission of light through the atmosphere; solar gain and attenuation; the transmission of solar energy through glazing; climate and the siting of a solar structure; the history of solar structures; passive solar collection; non-concentrating, active solar collectors; photovoltaic panels; smart grids, FiTs (feed in tariffs), and net metering; architectural considerations for capturing solar energy; and methods of energy storage.
One coil is connected to a boiler (or heat pump) and the other can be connected to solar thermal panels to store any solar gain collected during the day.
