LEED
A prescription for Sustainable Design
The LEED Rating System
recognizes the unique nature
of healthcare facilities while
maintaining close alignment
to LEED for New Construction.
2
Global
Engineering
Systems
understands
healthcare facilities have unique needs:
that
•Strict regulatory requirements
•24/7 operations
•Specific programmatic demands
•Energy and water use intensity
•Chemical use
•Infection control requirements
•Heightened need for patient privacy
•Health Safety Environment
Many healthcare facilities are already designed to be
long-lasting, durable buildings, a core principle of
sustainable design.

–
The design features of the chillers, which
account for upto 55 % of the total power
consumption, already exceed the ASHRAE
(American Society for Heating, Refrigerating
and air conditioning Engineers) standards of
baseline power consumption
The chillers are fitted with variable speed
control- one of the most energy-efficient ways
of operating chillers at the highest efficiency at
all capacity utilisation
The chillers selected are of the most modern,
energy-efficient one, and is being nowadays
sought after by many customers who are going
in for Green Building Certification
Variable speed control helps the power
consumption at all operating loads-especially
when there is partial load and is expected to
save about 25 % over conventional chillers
12
Energy & Atmosphere
How the chillers of Zulekha Hospital Project compare
• *Inference on the above comparison:
– Chillers installed for this project save a minimum of 25 % of
conventional chillers
* Source: website of York chillers
13
Energy & Atmosphere
Airconditioning – auxiliaries
– Chilled water system with pumps
controlled with variable speed to
save on pumping energy
– All AHUs (air handling units), which
together account for upto 10 % of
the total power, are also with
variable speed controls, enabling
optimum energy consumption at all
running times
– FAHU (fresh air handling unit) is with
heat recovery unit, thus utilising the
cooling energy of the exhaust air.
This design is also exceeding the
recommendations of ASHRAE
standards
14
Energy & Atmosphere
Airconditioning – AHUs & FAHU’s
– AHUs in OTs and ICUs have double
cooling arrangement, i.e provided
with units using chilled water coils
normal airconditioning units, so
that during chiller trippings, the
normal units can continue with
power supplied by the generator.
This will ensure continuous
availability of air conditioning
even when there is power trippings
15
Energy & Atmosphere
BMS (Building Management System)
– Chillers, pumps and the other auxiliaries are to be
controlled with BMS, thus enabling through
automatic operation, thus operation exactly to
the requirements, making the operation moreenergy efficient
– BMS will also ensure that the main and auxiliary
equipment all operate a optimum conditions
always, thus making the
process energy-efficient
– BMS also facilitates lesser
dependence on manpower
16
Energy & Atmosphere
Electrical & Lighting system
– Generator and UPS power supply systems-power supply for the
most critical areas such as Radiology, Labs, OTs, ICUs, etc. are
provided with uninterrupted power supply and generator supply
backup
– Secondary critical areas like cath labs, select HVAC systems etc.
are provided with generator power supply backup
– Power supply to OTs is provided through isolated power supply to
avoid any earth leakage problems
– Electrical system is to have capacitors to make the pf 0.99, thus
reducing fixed losses
– Energy-efficient lamps provided in the entire building,
– LED lights in common areas like lift lobbies especially in places
where there is round-the-clock lighting
– Lighting in common areas are to be regulated through automatic
controls, thus avoiding wastage
– Televisions provided in the patient rooms are to be of the energyefficient LED type
17
Energy & Atmosphere
Hot Water system
– Hot water recirculating pumps which
optimises the power consumption &
usage
– Stepless thyristor controlled calorifiers
which sequences all heating elements
operation as per temperature & water
flow demand
– Booster pumps will have energy
efficient type of capacity control
i.e variable speed drive, for both
cold water and hot water
18
Energy & Atmosphere
Medical equipment system
• Energy efficient LED lights for Operation theatres
• Energy & Water efficient CSSD equipment saves
approximately 75% water.
• Zero boil off MRI unit which requires less frequent
refilling of Helium
