Efficient Buildings in India: Opportunity Lost or the Opportunity of a Generation?

On a recent trip to India, the scale of construction and vitality of the country again struck me. India is undergoing a tremendous building boom; everywhere one goes the sky is full of construction cranes. To give a sense of the magnitude, a full 20% of the India’s GDP is construction, employing some 35 million people. In all this chaos is hope for the changing prospects for millions of people who are getting their family’s first shot at the middle class, modest as the Indian version is. But with this opportunity come several pitfalls. One of the consequences of the rapid growth is air pollution, now plaguing the country’s largest cities. Most large cities suffer rolling blackouts for a good part of the year; there simply isn’t enough power. The imperative to build more efficient buildings has never been greater.
India’s extreme pollution is compounded by ever-increasing energy demands and the continued use of coal-fired power plants.
Point Energy Innovations (PEI) is working with developers to design buildings that are significantly more efficient and more resilient. Efficiency allows for smaller cooling systems, transformers and generators. We are providing strategic-level design services to a massive new community representing over 10 million sq. ft. in apartment buildings, office buildings, hospital, hotel, schools, a shopping mall, greenways and a park. Two other developer clients are each building one million sq. ft. office buildings.
One of the two large-scale developments in India for which PEI is providing strategic design services, including specification of cooling, transformers and generators which require less power.
Many of the developers in India are new to the industry. In May I gave a talk to a young developers association; the members were all very sharp and mostly educated in top universities in the US or Europe. I was chatting with one of the attendees about his new residential project. When I asked the size, he casually responded 4.5 million sq. ft. Quite a surprise for me, but not uncommon in India. The need for housing and office space is immense. In contrast with the United States, a 4.5 million sq. ft. project is a once-in-a-lifetime opportunity and only for seasoned veterans.
Demand for commercial office space is driven by a mix of local and foreign corporations seeking to take advantage of the huge supply of software engineers and information workers in the country. When a company needs office space, they hire agents, usually international advisory firms, to represent them in their search. Typically, the agent issues an RFP to developers that include specific assurances for cooling systems and generator capacity, etc. It’s common to see clients requiring 8-10 watts per sq. ft. of generator capacity and 250 sq. ft. per ton of cooling system equipment sizing. These companies will go so far as to say if you don’t have this, then our client is not interested in leasing space your building.
With our projects, we have demonstrated an alternative, one whereby developers can bring their construction costs down by making more efficient buildings. We help clients select better windows, more efficient curtain walls, LED lighting, improved insulation and energy-efficient chilled water plants for HVAC systems. More efficient buildings require smaller chilled water plants, transformers and generators and are thus cheaper to build. These buildings only require 4-5 Watts per sf of generator capacity 400-500 sq. ft. per ton of cooling system capacity. This is half of what tenants and their agents require.

Herein lies the dilemma. The more affordable building is the more efficient building. The more efficient building should provide lower rents to tenants and help deal with India’s struggling power sector and air pollution. But developers are reluctant to go against the standards that agents for those tenants have set.
A new standard is needed. We have encouraged our developers to guarantee temperatures for cooling systems and uptime on electrical systems instead of actual sizes. And we have initiated conversations with two of the international real estate consulting firms with a broad reach in India. It will take some time to change this paradigm. Unfortunately, the paradigm is one which was developed in the US and Europe. All too often, in my work in the US, I see tenant agreements with power requirements based on Watts per sq. ft., and cooling based on sq. ft. per ton.
PEI’s design of advanced chiller plants results in lower power requirements.
Every building built in India during this construction boom that uses the current metrics thereby missing the benefits of efficiency, is a lost opportunity. The building sector needs to catch up to other sectors such as transport and renewables generation. India plans to ban all internal combustion cars within the next 13 years. Speaking at the World Economic Forum, Piyush Goyal, India’s Energy Minister, says, “Not a single petrol or diesel car should be sold in the country by 2030.” The government is actively encouraging photovoltaic-generated (PV) electricity. And utilities are not resisting, unlike in some parts of the U.S. PV systems on commercial buildings are being installed widely. Recent central utility scale PV bids have been at less than $0.02/kWh. This represents some of the lowest pricing in the world.
One thing Silicon Valley has taught me is: when there is gross market inefficiency, it’s only a matter of time before a new business model emerges. New leasing models and requirements based on delivering services – not size – need to become the norm. More efficient and lower cost buildings are a win-win for both developers and tenants alike and cannot come soon enough to the booming construction industry in India.
