EP100 Member Case StudyGodrej Industries
Factories in Valia, Ambernath, Uppal, and Taloja, India
Godrej Industries – a holding company doing business in consumer goods, real estate, agriculture and gourmet retail – has set its sights on cooling efficiency for the long haul.
Having already made strides in increasing energy efficiency, reducing water use, and incorporating renewable energy, the EP100 Cooling Challenge helped Godrej assess the long-term implications of its cooling loads and create a vision for greater cooling efficiency.
As the company works to achieve carbon neutrality, improving cooling efficiency stands out as a key opportunity to both cut costs and decarbonise.
"The EP100 Cooling Challenge has helped us be more precise on where we want to be for cooling efficiency in the next 5-10 years.”

Taking Positive Steps
At its chemical facility in Ambernath, Godrej plans to modify its schedule for flaker operations to enable the facility to turn its chiller off for at least 24 hours each week.
Turning off the equipment could save more than 190 megawatt hours per year (MWh/yr) and reap US$20,000 in cost savings annually.
Godrej is also investing in measures with a payback period of more than two years. For example, it purchased a new chiller for its chemicals facility in Valia that is significantly more energy efficient and uses a lower global warming potential (GWP) refrigerant.
The new equipment came at a higher upfront cost but will yield US$14,000 in cost savings annually.
Investing in real-time monitoring and controls will further optimise the setpoints of Godrej’s cooling equipment and achieve deeper savings.
Top-level support for sustainability
Support from the top has been critical to Godrej’s sustainability accomplishments.
Management identified cooling efficiency as a key area of opportunity, and then established goals and processes that enabled its facilities to move forward.
Godrej offers incentives to employees – in both the corporate offices and in plants – who achieve their sustainability performance targets.
"The drive for sustainability comes from Mr. Godrej himself.”
