Hotel merges sustainable design and energy usage

Located in Hyderabad, India, and designed by New York-based Skidmore, Owings & Merrill, The Park Hotel Hyderabad features a highperformance curtainwall with a perforated aluminum screen that provides sun shading and privacy for the guests, while still allowing for views of the city.

A new flagship hotel for The Park Hotel Group, the 531,550-square-foot, 270-room hotel infuses a modern and sustainable design with the local craft traditions, while being influenced by the region's reputation as a center for the design and production of gemstones and textiles.

Inspired FaçadeIn addition to a number of sustainable design trends, special attention was paid to the building's relationship to its site, daylighting and views. The building's three sides wrap around an elevated central courtyard that can be accessed from the hotel lobby. Protected from strong winds, this flexible outdoor area serves as an extension of the restaurants inside, and features a private dining court and swimming pool. Inspired by the metalwork forms of the Nizam crown jewels, the city's historic ruling dynasty, the nine-story hotel's unique perforated metal exterior provides a range of transparency. Perforated and embossed metal screens over a high-performance glazing system give privacy to the hotel rooms, while allowing diffused daylight to enter the interior spaces that reflect traditions of patterning, craftsmanship and style, all while providing acoustic installation from nearby passing trains.

The custom unitized curtainwall system consists of high-performance acoustic glass from China Southern Glass, Shenzhen, China, and 4-mm-thick ALPOLIC aluminum composite spandrel panels supplied by Mitsubishi Plastics Inc., Tokyo. The curtainwall system, including the custom aluminum screen, was manufactured, assembled and installed by Treviso, Italy-based Permasteelisa, with fabrication in the Thailand factory and assembly in the Bangalore, India facility. The project features more than 139,935 square feet of 3-mm-thick outboard, custom embossed and cutout aluminum screens supported by the curtainwall with small aluminum connector arms. The screen panels were fabricated and finished in Permasteelisa's Thailand facility and shipped to the project site.

Through collaboration with manufacturers, fabricators and researchers, this low-energy prototype building has reduced its energy use by 20 percent, and has an on-site water treatment facility and sewage treatment plant that processes both gray water for reuse and waste water for release back into the city's sewer system.

Completed in 2010, the project received the first LEED Gold certification for a hotel in India, and was awarded the Best New Hospitality Project of 2010 from Cityscape India. SOM also designed many of the project's interior spaces, including the lobbies, the lobby lounge, retail and banquet halls. With silver, gold and gemstones throughout, the interiors continue the jewelry concept.
