The document describes Kohinoor Hospital, a 227,000 square foot, 150-bed multi-specialty hospital in Mumbai. It has implemented numerous sustainable and energy efficient practices, such as using natural light, recycled materials in construction, an on-site water treatment plant for reuse, and solar panels. As a result of these initiatives, Kohinoor Hospital is the first and only LEED Platinum certified hospital in India, demonstrating industry-leading sustainability standards.

5. Features
 The Kohinoor Hospital is a 227,000 Sq.ft. with 150 bed health
care facility that houses 2 basements, ground+5 storey
structure.
 It is a multi-specialty hospital is implementing a range of energy
efficient measures to reduce energy consumption, decrease
greenhouse gas emissions and improve the quality of patient
care.
 At Kohinoor Hospital, of all the materials used, more than 40%
is recycled material.
 Foundation of the overhead tank was built reusing scrap
material. Salvaged wood was reused for making frames which
helped to conserve trees.
 The hospital is built with an emphasis on getting natural lights
in all the patient areas, which reduces the consumption of
electricity. The large windows and open sky light keep the area
cool and ventilated along with incoming natural light.
 The waste water from various zones of the hospital is treated
using disinfectants at the Sewage Treatment Plant. The water is
then reused for flushing, cooling air conditioning towers, DG
sets and for horticulture. Therefore conserves 40% of the water.

6. Features
 Also have dual flushes and urinal sensors in place to control water flow.
 Installed state-of-the-art Demand Control Ventilation and Variable Air Volume
systems to keep indoor air quality in check. This system uses sensors to
monitor the quality of air and keep it fresh.
 To prevent an Urban Heat Island Effect, where a particular area becomes
hotter than its surroundings, solar energy pavers and panels have been used.
 The hospital has also installed advanced internal and external electrical
systems to automatically adjust the lighting levels needed during the day and
at night.
 The only hospital who uses Earth Leakage Circuit Breakers as a measure
against electrocution.
 In case of emergencies, the hospital is well prepared with public address
system, fire hydrant system, fire alarm system along with smoke detectors,
heat detectors and sprinklers. There is also a emergency lighting for all exit
signs and on escape routes.

7. Features
 Energy Use Intensity at 53 KBTU/ Sq. Ft./ Yr.
 Insulated walls with a very low ‘U’ Value.
 High Performance glass, optimal Window to wall ratio, and
recessed and shaded windows.
 Very low LPD. Typically, artificial lighting constitutes 20% of the
overall energy load- where we have an almost 50% saving. Also
the useof LEDs and low LPD results in substantial reduction in
internal heat gain.
 The chillers have a high COP, which along with Heat Recovery (in
non –critical areas) VFDs on CT and AHUs contribute to low
energy demand.
 Onsite sewage treatment plant recycles 100% of grey and black
wastewater.
 Nine different varieties of vegetation was used in the landscape
with all with a water requirement of zero.
 storm water collector has filters with a 90% removal of total
suspended solids removed before being discharged.
 100% of the waste produced was reused, recycled, or given to the
local of community to be used.

8. Certifications and Especial Features
 Kohinoor Hospital is Asia’s first LEED Platinum Certified hospital and the
world’s second LEED Platinum Certified hospital. For a Platinum rating, one
has to achieve 52-69 points.
 Kohinoor Hospital has been awarded 54 credit points, making itthe only LEED
Certified platinum rated hospital in Mumbai, India.
 30 percent more of pure air is circulated as compared to other constructions.
 use astronomical time switches for controlling external lighting. These
switches are programmable on the basis of sunrise and sunset, and work
without the use of light sensor. This saves substantial amount of electricity
and increases the life of lamps. A green building consumes 0.66 watt /sq. ft.
as compared to a normal construction which consumes 2.0-2.5 watt / sq. ft.
 Green roof provides insulation for the building from outdoor environment. It
helps us to lower urban air temperatures and combat the heat island effect.
 solar plant installed on the roof, these solar panels are used to harvest the
solar energy which is the energy derived from the sun through the form of
solar radiation. Its use is to heat water and maintain the humidity in the
operation theatre.

9. HVAC
 HVAC Design includes the chilled water plants, these generally consists of
energy efficient screw chillers.
• Variable Frequency Drive (VFD) driven chillers
• Multiple primary chilled water pumps
• Secondary chilled water pumps with variable frequency drives.
• Condensing water pumps
• Fibre reinforced plastic (FRP) cooling towers
• VFD driven double skin air handling units with thermal break and variable
frequency drive.
• Fan coil units, chilled and condensing water piping, air distribution system,
insulation, electrical panels, wiring, control wiring and earthing.

10. Integrated Building Design System
 Building Automation System (BAS) is a micro processor control system which is
used to monitor and control all the parameters of HVAC, electrical, fire
protection, elevators and other building services/utilities.
 The DDC (Direct Digital Control) system interfaces with sensors, actuators and
environmental control systems, carries out various functions of energy
management, alarm detection, time/event/holiday/temporary scheduling,
communication interface/control and building maintenance and report
generation.
 Internal electrical system uses the latest technologies and fundamental
principles of energy conservation and safety that encompass protection
against electric shocks, thermal effects, over current, fault current and over
voltage.
 Dimmers are provided for lighting circuits to reduce the lux level at times
when higher lighting level is not required. Also sensors are provided to switch
off lighting when the space is not occupied or where natural light is available
to achieve the required lux level.
 The use of Earth Leakage Circuit Breakers (ELCB) is to safeguard against
electrocution through direct or indirect contact with a live circuit.

11. Landscaping
 In landscaping, the focus has been in using native
plants like roheo, chlorophytum, bahunia
purpuria, bahunia blackiana, plumeri alba, pisonia
alba, polyathia longifolia etc. that require less
water for survival.
