Daylight analysis for a Typical floor plan of Office Tower

OFFICE TOWER Office spaces on the North receive North light, with less glare with lux levels between 110-2200lux for upto 75% of their area. Office spaces on the West receive sunlight above 2200lux. To curb this, shading devices are placed on the West faรงade.

Shadow Analysis Preliminary shading analysis have been done for buildings on the day of vernal equinox, summer solstice, autumnal equinox and winter solstice. (10am , 12pm and 2pm)

Top view of the site showing shadows as on the 21st of March, June, September and December

Shadow analysis- View indicating shading of areas in the plaza

The north, north-east and north-west facades receives shade throughout the year. The south, south west and south east facades will have to handle more amount of heat and light throughout the year. To counter this, the south , south-west and southeast facades have been shaded using vertical and horizontal shading devices. The office tower that is not shaded by the large roof-form is designed such that the east and west facades are of lesser width. The majestic roof form provides

The waiting lobby receives day lighting between 110-1100lux for most of its area. The ticket counters receive between 110-550lux. The upper class and premium waiting halls also receive day lighting between 110-1100 lux. The first floor of the railway component comprises of the food court that has between 110- 1100 lux. The dormitories around the sky courts have between 110-550 lux of day lighting.

The second floor of the railway station comprises of mostly services and the dormitories. The dormitories have a day lighting of 550-2200 lux. It has been placed around the atrium to use natural light to its maximum potential. Shading devices like curtains and blinds will be used to cut the glare.

SMART HUB

COMPONENTS 2km

The Amaravati Master Plan is based on a 1Km grid system. The Smart Hub module integrates into the same 1Km hub at varying scales ranging from XS – L based on the location. This makes the entire cluster self sufficient providing last mile connectivity, public convenience to people of Amravati.

Void Deck Improves microclimate Increases wind speed by 50% Shaded space for children to play, eat and interact

West Facade Solid with no windows to avoid the harsh heat No glare

The design of the secondary school focuses on a porous massing and form. The class rooms are placed opposite to courtyards, with South West being the predominant wind direction. A central courtyard provides natural light within, while allowing the floor plate to be of optimal depth. A solar canopy was suggested to cover the roof, while keeping an ante space below to reduce heat gain. The void deck increases the wind speed by 50% in the ground floor, while also providing shaded areas for the students
