It was a challenge for designers to produce a design concept appealing to Palace standards and at the same time energy

efficient with sustainable design meeting Platinum standards.

This was achieved by way of working in parallel with Architect in USA, MEP consultants in Delhi, Structural

Consultant in Mumbai, Interior and Lighting consultant in USA, F&B consultant in USA.

Due to restricted times line & to open the hotel before the CWG games, dedicated team was assigned in office to work

on the MEP & Green design so as to produce an integrated design at all stages of the development involving close

coordination with Architects, Structural consultant, Interior designers, F&B, Lighting consultant. Compliance with

international & local codes and prevailing practices.

LEED Analysis

Green Building Design: Hotel Leela Palace followed green building practices to substantially reduce or eliminate negative environmental

impacts and designed to reduce operating costs, to contribute health and wellbeing of the occupant and reduce

potential liability resulting from indoor air quality problems. Project team has considered several environment

friendly design and measures which led to meet ‘LEED India Platinum Rating’ requirements. Designed Green

Building features as stated below are incorporated in all phases of construction and shall be followed and

maintained during post occupancy of Hotel Leela Palace.

Hotel Leela Palace site is well located with pedestrian access to ample number of basic services and public

transportation services like bus and rail to reduce pollution from private automobile use.

Designed, implemented erosion & sedimentation control measures during construction and post occupancy by

retaining top fertile soil for landscaping within site, reduction in air pollution and water pollution through efficient

storm water management and dense landscaping.

Project parking is designed as per Delhi Development authority. Parking is facilitated with electrical charging

stations so as to encourage usage alternative fuel vehicles and also considered exclusive parking spaces for car pool

services to reduce environmental impacts.

LEED Analysis

Designed efficient Rain Water Harvesting (RWH) system to recharge site aquifer through recharge pits so as

to reduce storm water run-off volumes after post development and these RWH pits will be cleaned and maintained

periodically.

All exposed roof of Hotel Leela Palace are cent percent covered with vegetation and high Solar Reflective

Index (SRI) paint material to maximize energy savings and minimize heat island effects.

Sewage Treatment Plant (STP) is designed which shall treat 100% waste water generated from the building

during post occupancy phases of the project to eliminate potable water usage for irrigation, cooling tower makeup

and flushing,

LEED Analysis

By installation of low flow fixtures, project saves potable water to an extent of 41%.

By efficient envelope, lighting and systems, project saves 56.93% in energy costs over ASHRAE 90.1 – 2004

baseline.

All the building energy systems and system components are commissioned, measured and verified in accordance

with the operational requirements of the building owner and the design intent.

Designed measurement & verification plan to verify the cost savings associated with energy efficiency measures

incorporated into the design, and to provide a recalibrated energy model that will serve as a tool for building opera

tors in identifying and remedying causes of underperformance.

Reduced ozone depletion and support early compliance with the Montreal Protocol through HCFC & Halon

free based HVAC&R and fire suppression systems.

Diverted more than 95% of construction waste from landfills and routed to recycling zones and reused the

construction waste appropriately.

To encourage recycling activities, Hotel Leela Palace facilitated separate space for segregation and collection of

recyclables (Paper, Plastic, Metals, Glass etc.,) generated in the project during occupancy.

Locally sourced materials with high recycled content and rapidly renewable content to reduce impacts resulting

from extraction and processing of new virgin materials and environmental impacts.

LEED Analysis

Declared as NO SMOKING zone and well communicated to building occupants through web check-in and

signage’s.

Maintained Construction Indoor Air Quality (IAQ) during construction and before occupancy as per Sheet

Metal Air Conditioning National Association (SMACNA) guidelines.

Designed ventilation systems as per ASHRAE 62.1 – 2004 Std and monitored through CO2 sensors

connected to Building Management Systems (BMS) to contribute health & wellbeing of the building occupant.

Reduced the quantity of indoor air contaminants that are odorous or potentially irritating harmful to the

comfort and well-being of installer and building occupants through low emitting adhesives & sealants, paints,

composite wood.

LEED Analysis

Selected Carpet Rug Institute (CRI) Green Label Indoor Air Quality Test Program certified carpets.

81% of the building occupants are having individual control over lighting systems and thermal comfort to

promote the productivity and wellbeing of the occupants.

Designed comfortable thermal environment throughout the year as per ASHRAE 55 Std in view of Delhi

climatic conditions.

To decrease the consumption of potable water for flushing & landscaping water requirements treated water

from STP is used.

To reduce the site disturbance, green area provide in our project is 25% more than the local norms. The species

where selected of native/adaptive nature to reduce the consumption of water.

Car parking with 3% of Alternate fuel vehicles with electrical charging points provided in our project.

5 % of the car parking for car pool is provided in our project.

Energy conservation and ECO friendly Measures -

Dual Fuel Gas Generator – 1900 KW In dual fuel engines equipped with a carburettor, an air/gas mixture is brought to the cylinders and then

compressed. A small amount (about 8% of the energy-input) of gasoil is injected for the ignition of the mixture.

Heat Recovery Vapor Absorption Machine Our hotel is equipped with dual fuel gas generator of 1900 KW. The flue gas waste heat is being used to run the

Vapor Absorption Machine. The heat recovery is approximately 720 TR capacity.
