India Advantage
Healthcare revenue in India is set to reach USD160 billion by 2017; expenditure is
likely to expand at a CAGR of 15.2 per
cent over 201117.
Rising incomes, greater health awareness, lifestyle diseases and increasing access to
insurance will contribute to growth.
Investment in healthcare infrastructure is set to rise, benefiting both hard
(hospitals) and soft (R&D, education)
infrastructure.
Medical tourism is emerging as one of the most lucrative investment areas in the
country.
Availability of a large pool of well-trained medical professionals in the country.
India has an advantage over its peers in the West and Asia in terms of cost of high-
quality medical services offered.

Given the backdrop of the power scenario, the way out to resolve the crisis is to reduce the demand to match with
the available supply.
As there remain a lot of social issues in bringing down the existing demand, the fresh demand that is being added
into the system should be managed.
Rational use requires that we obtain maximum efficiency from the energy consumption and from the facilities
required for the generation and distribution of such energy.

Designed to automatically manage a daily rhythm of light, promoting sleep-wake rhythm.
For better look out and healing environment, a colour rendering property and light reflectance values (LRV) shall
be ensured.
High Energy efficient light fixtures such as CFL, FTL (T5 lamps) and LED type pendant light fixtures in operation
theatre (replacement of Metal halide light fixtures) are
mostly used across these buildings,
The luminous efficacy i.e., Lumens per watts is increased without compromising the Illumination requirement in a
particular location.
SPECIAL CONSIDERATIONS:
Sustainable Lighting Solutions for a Healing Environment in patient
rooms

-
L&T CONSTRUCTION B&F EDRC - CHENNAI
A Centralized lighting control system is used to control the
light fixtures in common
areas like corridor, Lobby,
etc. across various floors in
the multi-storey hospital
building.
The centralized lighting control panel can be
integrated with centralized
BMS system interfaced via
Programmable Logic
Controller..
Remote operation via BMS provides an integrated
approach to control and
energy management.
LPD of 0.8 to 0.9 and total power load percentage of 6.5
to 7.5% is achieved against
the requirement of 25% for
lighting load from the total
power requirement.

Elevator is a mechanical device which is used for vertical
transporting of people or goods from one level to another.
This is treated as one of the lifesaving element.
Gearless types elevators are emerged as effective one and control drive with VFD working in closed loop system.
This paves a way to reduce the energy requirement much appreciable value due to the advantage of requiring a less
powerful motor to turn the sheave.
This type of Elevators is proved to be efficient in terms of operating speed as well.
This way, the power requirement has been brought down to 4% from the total power requirement against 15%.

Public Health Engineering (PHE) system, as a part of waste management system and infection control, an
amount of power is required to carry out certain
activities like Sewage treatment plant, Water treatment
plant and other treatment plant for radioactive wastes,
Infectious waste, etc.
This contributes to 10% of the total power load.
It is necessary to explore Energy efficient equipments such as selecting maximum efficiency between 70% to
80% for pumps/motors and Solar geysers/heaters for hot
water supply network with Electrical power back up.

Medical equipment also known as Life support is
designed to aid in the diagnosis and is used greatly to
maintain a patient's bodily function.
Monitors to measure patient vital signs and other parameters.
Most of them of Electro medical installations are of sensitive electronic equipments.
In a hospital building, Electro medical & its related installations contribute to 20% approx. of the total power
requirement in that building.
This Power electronic equipments are susceptible to mis-operation caused by harmonic distortion.

Non-linear medical equipment's and sensitive loads like CATH lab, MRI CT scan, LINAC, PET
CT, etc. loads should be designed such that to have
separate impedance.
Using a separate feeding circuit for separate loads can reduce shared impedance and minimize load to
load interference.
Load balancing should be achieved for better and efficient operation such that life cycle of the
equipment's installed can be ensured very high.
