2. INTRODUCTION
Green building also known as green
construction or sustainable building, refers to both a structure
and the application of processes that are environmentally
responsible and resource-efficient throughout a building's life-
cycle: from planning to design, construction, operation,
maintenance, renovation, and demolition.
Although new technologies are constantly being developed to
complement current practices in creating greener structures,
the common objective of green buildings is to reduce the
overall impact of the built environment on human health and
the natural environment by:
Efficiently using energy, water, and other resources
Protecting occupant health and improving employee
productivity (see healthy building)
Reducing waste, pollution and environmental degradation
3. Concept
Green building is a whole-systems approach for designing and constructing buildings that
conserve energy, water, and material resources and are more healthy, safe, and comfortable.
Many think of solar panels when they think of “green” building.
Benefits
Energy efficiency is one of the primary advantages of green building
Orient the house to reduce solar gain in summer and capture the sun’s light and warmth in winter.
Maximize natural light to reduce the need for electrical usage during the day
Reduces air pollutant quantitatively.
Create a national network of green corridors and nature reserves.
Design Considerations
Design an energy-efficient building
Design buildings to use renewable energy
Optimize material use
Design for future reuse and adaptability
5. INTRODUCTION
It is Nestled in greenery in the heart of Delhi. The ITC
Maurya, has been the preferred residence of visiting
heads of state and global business leaders for over 25
years. It is a tribute to the age of the great Mauryan
Dynasty, which created the golden era of Indian history.
It showcases Mauryan Architecture. The hotel uses a
signature ‘East meets West’ style of Mauryan diplomacy
that combines a historic aura with contemporary facilities
to create a luxury hotel experience.
It consists of 440 rooms, including 29 uniquely-designed
suites. The interiors of these suites provide a whiff of the
Gupta Empire, the polished marble, carved teaks, stone,
& iron caste structures define the Mauryan period.
6. SITE CONTEXT
ITC Maurya has come to be known as
the “Greenest Luxury Hotel Chain In
The World,” Certified by LEED
(Leadership In Energy &
Environmental Design).
Its premium hospitality chain has
successfully incorporated its
philosophy of “Responsible Luxury”
– combining elements of luxury &
environment-friendly operations.
7. The building consciously promotes cultivation
of native plants (covering more than 25% of
building area).
The hotel’s rain water harvesting capacity, is
30% of the peak rainfall. This helps in
reducing water demand & run-off.
Over 75% of roof area is covered with a
special paint that has a high Solar Reflective
Index, thereby reducing the cooling demand.
Exterior hardscape is maintained without use
of chemicals.
8. DESIGN
The design was inspired by echoing the design of a Buddhist stupa.
Lobby recreates the paneled dome of a chaitya.
9. Low window to wall ratio(WWR). Reduces the building cooling load.
65% of the area have day lighting. Reduces 5% of energy consumption.
Window over-hang. Reduces 1% to 1.5% of energy consumption.
North east ->Double glaze unit
South west ->Low U double glaze unit
10. Roof top vegetation is 15%of total roof. Reduces 1%of energy consumption.
Thermal resistant glazing. It reduces 2.5% to 3.5% of energy consumption.
11. Air filtration
Solar concentrator
Utilisation of waste material as fuel.
42.99% is recycled and
the rest is disposed.
Hydrophonic

13. 1. ENERGY EFFICIENCY
ITC Maurya uses 23% less energy than USGBC [U S
Green building council] national average for large size
luxury hotels.
Heating, ventilation and air conditioning [HVAC]
system, thermal system, water management system
and building management system underwent retro-
commissioning to enhance performance efficiencies.
Usage of solar thermal system for hot water and low
pressure steam application.
The Arun system and Thermax system were installed.
14. 2. WATER EFFICIENCY
ITC Maurya consumed an average of 1300 kilolitres of water, per day
ten years ago.
The average consumption was down to 800 kilolitres until a couple of
years ago.
Now, the hotel consumes 625 kilolitres of water on an average & is
striving to bring the consumption level down to an ambitious 450
kilolitres of water per day.
ITC Maurya boasts of being a water-positive facility, It is able to
generate more water than it consumes.
ITC Maurya has minimised consumption of water, energy & all other
natural resources.
15. Sensor operated and waterless urinals, dual
flush closets have reduced the water
consumption by 33%against USGBC
standards.
Treated recycled water is used for landscape,
cooling tower and miscellaneous cleaning
resulting in further reduction of water
consumption.
Excess treated recycled water is given to
Government Bodies for irrigation of
landscapes, gardens & forests.
Reduced water demand in Cooling Tower
through automation.
16. 3. SUSTAINABLE DEVELOPMENT
The hotel’s rain water harvesting capacity, is 30% of
the peak rainfall. This helps in reducing water
demand & run-off.
Steps have been taken to protect the ecological
stability of the immediate surroundings & landscape.
The building consciously promotes cultivation of
native plants (covering more than 25% of building
area).
Over 75% of roof area is covered with a special
paint that has a high Solar Reflective Index, thereby
reducing the cooling demand.
Exterior hardscape is maintained without use of
chemicals.
17. 5. SUSTAINABLE
More than 50% of ongoing consumables used at ITC Maurya
are either local or recycled. Low VOC (Volatile Organic
Compounds) paints & FSC (Forest Stewardship Council)
certified wood is used for refurbishments & renovations.
More than 30% of the food & beverage used is harvested &
processed locally within 160 kilometres of the hotel.
Usage of LED lamps that are energy efficient & no mercury
content.
More than 99% of the total solid waste is either reused or
recycled through Recycling programs or converted into manure
by Organic Waste Converter.
18. 4. INDOOR AIR QUALITY
Increased treated fresh air
infusion for higher human
productivity and better health.
Enhanced occupant thermal
comfort.
Green Sealed certified
Housekeeping chemicals and
equipment.
Mechanical means of elimination
of rodents and use of eco-
responsible pesticides.
