This document provides a case study of the ITC Hotel headquarters in Gurgaon, India. The 170,000 square foot building was designed to be a platinum-rated green building, achieving annual energy savings of 20 million kWh compared to a typical building of similar size which would use 35 million kWh per year. Key green features included the use of fly ash cement, double glazed low-e windows, energy efficient lighting and appliances, rainwater harvesting, wastewater recycling, and solar hot water systems. The L-shaped design maximized natural light penetration while ensuring parts of the facade remained shaded.

GURGAON
CASE STUDY

2. INTRODUCTION
• Location : Gurgaon, India
• Floor area: 1,70,000 sq. Ft
• Architect: Rajender Kumar and Associates
• Significance: Platinum Rated green building
• Rated by: USGBC-LEED ( US green Building
Council-Leadership in Energy and
Environment Design
• Year : 2004

3. ENERGY CONSUMOTION STATICS
• Normal building of similar area: 35,00,000
kWh/year
• ITC Green centre: 20,00,000 kWh/year
• Annual energy savings: Rs. 9 million
• % increase in initial cost: 15%

4. ORIENTATION
Design Intent:
• High energy efficiency of the façade with
optimum light transmission.
• On the Northern side, the glass solution was
required to give a higher light transmission
due to the orientation of the building.

5. BUILDING DESIGN
• By giving the ‘L’ shape
configuration the width
of the floor Plate is
reduced for the same
amount of floor plate
area thereby allowing
natural light to penetrate
deep into the interior
spaces.
Site Plan of the ITC

6. The building is a composition of three parts:
• Two office wings are held together by a central
atrium that as an ensemble creates a large L-
shaped figure focused on an exterior
landscaped court.
• The L-shape blocking ensures that part of the
façade is always shaded.
• The L-shape office wings end into hexagonal
ends that make a very strong presence on the
approach roads.

7. GREEN FEATURES OF THE
BUILDING
• Fly Ash based cement used.
• The glazing for the building has been designed
to maximize the effect of natural sunlight,
largely eliminating the need for artificial ones.
• Double glazed windows with low-e coating.
• CFC, HCFC & Halon free air- conditioning system
• Energy efficient lighting (T5 lamps with
electronic ballast, high efficient luminaires)

8. • Water saving techniques-Rain water
harvesting.
• Water efficient landscaping.
• Sewage treatment plant and waste water
recycling.
• Eco friendly house keeping chemicals &
practices.
• Use of recycled materials.
• Installation of solar hot water system and
solar concentrator for kitchen.
