75F's Hiranandani Hospital Case: 16% Energy Savings

Content

Hiranandani Hospital — a 258,334-square-foot critical-care facility in Powai, Mumbai — partnered with 75F and achieved a 16 percent reduction in energy consumption versus baseline, saving 795,266 kWh across its Chiller Plant and Air Handling Unit (AHU) operations over the two years from July 2023 to August 2025. Verbatim from the 75F case study: "75F's IoT-based Building Management System (BMS) facilitated significant energy savings for Hiranandani Hospital. Within 2 years of installation from July 2023 to August 2025 the client has saved a total 795266kWh across the hospital's Chiller Plant and Air Handling Unit (AHU) operations." Hiranandani Hospital had been running on dated HVAC assets that could not operate at optimum levels, with only a partially working BMS that offered no real-time monitoring or centralized control of its AHUs and chillers. The facility management team needed automation, simplified energy dashboards, and reporting — and, per the case study, upgrading to 75F's IoT-based BMS was also "essential for the facility to apply for green building certification." The deployment ran from mid-January through mid-April 2023 — a 90-day retrofit with zero downtime, as 75F's specialized execution team worked nights to avoid shutting down HVAC systems in a critical-care environment that could not tolerate outages. Tata Power Trading Company Limited (TPTCL), the integrated power company that supplies electricity to Hiranandani Hospital and a 75F partner, identified these needs and initiated the engagement. 75F deployed its proprietary IoT-based BMS across the reception, lobby, outpatient department, laboratories, and patient rooms, with customized dashboards surfacing energy consumption, emissions, and spend for the facility team. Implementation had to be designed for an environment that could not tolerate HVAC shutdowns, so 75F selected the most appropriate configurations and worked nights to keep the critical infrastructure online throughout the retrofit. Beyond the 16 percent energy reduction and 795,266 kWh saved, the case study reports a 628-ton reduction in CO2 emissions — equivalent, per 75F, to the carbon absorbed by 9,305 tree seedlings over a decade — and an annual electrification footprint equivalent to powering 900 Indian homes. 75F's Managed Services team also took over the site post-commissioning to keep it operating at peak energy-efficiency. The case study frames the engagement as a foundation for "alignment with global sustainability objectives," and explicitly notes that the 75F BMS upgrade was a prerequisite for Hiranandani Hospital's application for green building certification — positioning the deployment as a baseline for additional sustainability programs at the hospital going forward.
