PROJECT INFORMATION
Sustainable High-Rise Oasis
Thinking about high rise, a tree came into mind which is a natural highrise structure. Thus decoding the tree with high rise similarities were found. The circulation of core resembling the xylem phloem of tree. The facade with bark of tree, branching of tree with the lobby branching the hotel rooms. Thus celebrating the defects in trees resembling them with a recreational floor in design.
Intro: The Paradise Hotel is a Multistoried Business Hotel in the bustling city of Ahmedabad. Towering over the breathtaking Sabarmati river, this structure is designed as a net zero building.
Location: Location of the hotel is based on high proximity of the city, and well connected with the road networks, targeting the market segments that will become the beacon and identity of the city.
Site: Site of 5.13 acres land decoded with road setbacks as 15m and side 7.5m. The buildable area of 15,000 sq.m according to the local byelaws.
Design Goals: Design goals orienting towards sustainability and user experience included, social impact, health and wellbeing, resilience, renewable onsite energy, embodied carbon, daylight, landscape, engineering and operation, water performance, sewage treatment, HVAC and service.
Form: The form was modulated such that the building forms multiple green pockets at different levels acting as spaces to interact, socialise and celebrate. The pockets are further oriented such that it maximises the views meanwhile the sustainable features like double facade, kinetic facade helps to control the solar gains from the south. The built spaces and landscapes balance the environment creating a suitable microclimate with richer flora and aura on the site.
Kinetic Facade: Minimum SHGC glass used on south and west facades from the AIS brochure, double low E-glass with 12mm air gap, ecosense clear marvel and blue berry plus glass is used for facade windows and doors.
The building is equipped with kinetic façade for fighting against harsh climate. The double-skin façade also acts as a thermal and acoustic buffer protecting against heat gain/loss and high wind speeds.
The integration of kinetic system with sun hours such that from the shift of east to west the facade opens and closes according to sun angle.
Thus the opening of kinetic facade with the sun path, facade closes when sun approaches.
The integration of kinetic façades that are light sensitive, responds to the movements recorded from the sun paths. The system of kinetic facade movement gives a signal to mechanical ventilation in buildings.
The system allows natural ventilation as the kinetic façade senses the light and opens. Vice versa, the system activates mechanical ventilation as the kinetic facade modules close. To customise the user needs the kinetic façade has variable façade system control which can be monitored.
This creates the double façade of kinetic curtain to the building.
Sustainable Strategies: Path towards sustainable net zero goals includes water, energy, waste management, pursuing the net positive goal.
Sustainable strategies in the project include water management from stormwater, and rainwater harvesting. Two rainwater harvesting tanks underground are integrated to merge with the landscape above.
Calculations for Rainwater Harvesting Tank: In the wastewater cycle, the grey water is treated in a reed bed system and collected and used for landscape irrigation, and separated black water from the septic tank is reused to flush toilets.
