Asset aura is a high-rise residential building with ground plus five floors. Excess heat gain into the building is avoided by orienting the building appropriately. The external walls are built using autoclave aerated concrete (AAC) blocks which offer better insulation properties compared to regular burnt bricks. External shading elements in the form of overhangs, and high performance double glazed windows have been provided in the building to reduce solar gains through windows.
The building envelope comprises of heavy weight construction. The external walls are made up of AAC blocks and rendered with external plaster measuring a U value 0f 2 W/m2K.
The ground floor comprises of 1 cm thick vitrified tiles, 5cm thick cement mortar, 15 cm thick RCC slab and 20 cm thick cement plaster with the U value 0f .33 W/m2K and total surface area of 3,340 m2.
The external roof of the building consists of 30 cm thick external coir pith, 5 cm thick geo textile, 15 cm thick RCC slab and 20 cm thick internal ceiling plaster measuring a U value of .44 W/m2K and a surface area of 3,340m2.
All windows are double-glazed with gas filling (SHGC 0.45) and aluminium frame. Total window area inclusive of the frame is 1,028 m2.

The building has been designed for natural ventilation, with proper arrangement of windows to enhance cross ventilation in the building.
There is adequate daylight in the building and high performance glazing has been used to reduce the solar heat gain in the building. Most of the materials used, by quantity, for subassembly, internal partitions, false ceiling, and in built furniture are obtained from low energy materials having recycled content. Flush doors and granite doorframes have been installed in order to reduce the usage of hard wood in the interiors.
There is no central heating or cooling system installed in the building. Most of the spaces of the building are designed for natural ventilation.
