A report by McKinsey & Company states that 70 percent of
India is yet to be built. However, the existing stock of residential and
commercial buildings across the country has already put an immense pressure on
the resources as they guzzle huge amounts of energy and water. In India during
2011-12, electricity alone accounted for more than 57 percent of the total
energy consumption, with 40 percent of electricity being consumed by building
sector, reveals National Statistical Organisation’s (NSO) Energy Statistics
2013.
Existing buildings in India guzzle huge amount of energy and water
Experts suggest that existing buildings hold a lot of
potential when it comes to energy and water savings if they are retrofitted
with green and sustainable features. LEED for Building Operation and
Maintenance (O+M) rating system is a tool that is helping improve the
efficiency of existing buildings across the globe, thus reducing their carbon
footprint.
India has also set its feet towards operational efficiency
as a national capital based building is the first in the country to adopt a
top-rated retrofit from the U. S. Green Building Council (USGBC). Paharpur
Business Centre, is touted as the healthiest building in New Delhi as it boasts
of an air filtering technology that ensures best indoor air quality, and is
India’s first top-rated LEED O+M existing building. “Sustainability makes for good business and energy efficiency is a low
hanging fruit”, believes Kamal Meattle - CEO, Paharpur Business Centre, stating
that good indoor air quality enhances occupants’ health which leads to more
productivity and thus makes a good business case for brands and corporates.

NSO also reveals that by 2040, building
sector in India will consume 76 percent of electricity. A major chunk of
electricity demand is slated to come from the residential sector. The condition
will become more severe if the drought-like situation that the country is
facing currently continues. Hence, building green is no more an option for
India.
The green building movement, pioneered by
USGBC’s globally recognised rating system – LEED, has gripped the world with
excitement with steps taken every day to contribute to triple bottom line –
people, planet and profit. India too has marched towards sustainability as it
ranks third among top 10 countries for LEED green buildings outside United
States. Dodge Data & Analytics World Green Building Trends 2016 SmartMarket
Report, of which USGBC was a contributing partner, states that green buildings
will grow by 20% in India by 2018.
Green buildings development initially was
centred towards reducing environmental impact during design and construction
phase, which has now evolved to put much focus on optimising energy utilisation
and ensuring operational efficiency. Keeping this in mind, the latest version
of USGBC’s innovation – LEED v4, has been developed which emphasizes energy
efficiency and operational performance.
Operational cost savings has been one of the
major drivers of the green building industry growth. Presenting on the business
case of green buildings, USGBC has revealed that there has been a reduction in
operational costs by 13.6% for new construction and 8.5% for existing building
projects. Respondents of the Smart Market report hope to save 14% in
operational costs over a period of five years for new green buildings, while
they expect 13% operational cost savings over five years for green retrofit and
renovation projects. The report also reveals that 24% Indian respondents will
be undergoing existing building retrofit.
Even after achieving the highest level of
the world’s premiere green building rating system - LEED Platinum, certain projects
are constantly taking steps to enhance operational efficiency. “We have decided
to go for conversion of CFL/PL/T5 and T8 into LED in current financial year to
reduce further unit consumption”, said Dibakar Mishra - Sr. Manager Project,
Wokhardt Hospitals Ltd – Wockhardt South Mumbai is the first hospital in Asia
to earn LEED Platinum certification.

USGBC has extended its innovation to
developing the LEED Dynamic Plaque which helps gauge the performance of a
building in real time. It’s a scorecard of the building that doles out
information based on energy and water consumption, waste, transportation and
human experience.

Operational efficiency translates into
enhanced building performance. “20% energy performance can be enhanced with
improvement in operational efficiency”, said Rumi Engineer - Sr. General
Manager, Energy Management and Greener Initiatives, Godrej & Boyce.
Citing how commissioning is important for
operational efficiency and what is required to measure building performance, Rajat
Malhotra – COO West Asia, Integrated Facilities Management, JLL said, “A
transparent reporting mechanism is crucial to measure building performance. 90%
of buildings don’t get commissioned for HVAC, thus we need to interact with
contractors and engineers to resolve this. A commissioning report must be used
as reference for retrofits in the future. LEED is forcing an advanced commissioning
which is very good.”
“Performance period must be continuous. It
should be between 3 months and 2 years,” said Ken Simpson, Director,
Energy/HVAC, Green Business Certification Inc. (GBCI) while mentioning what
steps could to taken for operational efficiency. “Reading energy bills,
auditing waste, banning smoking, surveying indoor air quality are the few
things that one can do,” added Simpson.
He also stresses on the need to conduct
energy audit as energy auditing and commissioning can provide savings of 10-20%
with an average payback of slightly over one year.
Skilled and trained staff is also the need
of the hour when it comes to maintaining the operational efficiency of the
building as pointed out by Engineer. Building owners can take inspiration from
organisations of developing counties who are using online courses to train
green accountants who will be responsible for tracking factory emissions and
carbon-offset credits as part of the Paris climate deal signed in 2015.
Putting focus on energy efficiency, Simpson
commented, “Paint everything white as lighter interior surfaces reflect natural
daylight into rooms, reducing electrical lighting needs.”

Citing its achievements, LEED’s role in
enhancing operational efficiency is therefore undeniable.
