DESIGN NAME: Arcot Plaza
PRIMARY FUNCTION: Sustainable Business Center
INSPIRATION: Usually commercial buildings in third-world cities like Chennai are energy-guzzlers with unplanned service lines all over and with fully glazed windows trapping the heat and are major fire-hazards. As an alternate, Arcot Plaza was designed after a detailed research to be a Sustainable Business Center which offered world-class commercial spaces for its users. From inception of the project care was taken to address the User comfort and ensuring the sustainable use of natural resources.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Arcot Plaza is designed to be a Sustainable Business Center which offers world-class commercial spaces for its users on an affordable budget. Design Objective’s achieved through the project are - 1) Creation of an Iconic Building with Lowest possible Budget 2)Natural Light without glare for Office spaces. 3)Climate Responsive Design with appropriate Shading Features and Lower heat-gain.4)Achieves maximum Revenue potential. Success - Maximum Rent/Sq Ft in Micro-Market. 15% Less Energy usage.
OPERATION / FLOW / INTERACTION: The Design idea was to maximize the visibility of the building and tap the potential in terms of footfall as the site is located between the existing railway station and an upcoming Metro Station. The ground plane was designed as a public zone. The front edge of the site was designed as a Public Plaza extending the pedestrian side-walk into the site with the building having an inviting double-height atrium for the Retail branch. The Office floors have a separate entrance lobby at the rear with a Vehicular drop-off. The terrace was designed to accommodate a large terrace garden which cuts the heat load of the offices and provides a break-out space for the Office workers

RESEARCH ABSTRACT: Sustainability_The Form of the Building was a direct response to the Climate. The Northern side faces the Street. Care was taken to protect the glass frontage of the building with appropriate and innovative shading-devices there-by providing effective day-lighting and reducing the solar heat-gain on the building. The Retail Facade is protected by the Office Floors Cantilevering from above. The Western and Eastern Side have been designed with appropriate openings to facilitate Cross-ventilation inside. The Building is designed to harvest 100 percent of the rain-water. Provisions have been planned for Grey-water recycling to reduce the requirement of the building on Metro-water. Solar energy use is planned for common areas. The walls are made of AAC blocks which has superior thermal insulation over bricks and is also more cost-effective as it reduces the dead-load of the building. Low-Maintenance Materials have been used which reduce the amount of energy spent on cleaning the building. Also most materials are locally available making replacements cheaper and easily available.
CHALLENGE: The Challenge was to design an Innovative Low-Cost Commercial Facade which could be mass-produced and provides constant day-light for Offices without glare.
Innovative Day-Lighting Facade_The Northern Facade of the Building for the Office Floors was designed to give glare-free day-lighting for the work spaces. The triangulated translucent poly-carbonate fins placed at carefully determined patterns cuts the direct sun-light. In Chennai during summer the setting sun moves northward. During such months the Fins provide diffused light. During other times they cut the glare from the bright sky. It also offers an interesting view to the street from the Office spaces breaking the monotony of the Spaces. Also the glass used is solar rated glass to cut heat-gain. The exploded diagram explains the facade construction system.
