Guaranteed MEP Energy Retrofit & Decarbonization for Existing Buildings

Yes. We specialize in live-building cutover execution. We achieve this by: (1) Installing temporary skid-mounted air-cooled chillers or mobile pumping bypasses; (2) Performing changeover work during cooler winter months or scheduled overnight windows; and (3) Replacing multi-chiller plants one unit at a time, ensuring remaining units carry the building load during the transition.

The International Performance Measurement and Verification Protocol (IPMVP) is the globally accepted standard for quantifying energy savings. It establishes a mathematically sound baseline before work begins, accounts for weather variations and building occupancy changes, and proves exactly how many kilowatt-hours and dirhams have been saved post-installation.

Low delta-T syndrome occurs when chilled water returns to the plant room too warm (e.g., return temperature of 10°C instead of the design 14°C). This forces chillers and pumps to run at maximum capacity while delivering inadequate cooling, causing high utility penalty charges. We fix it by replacing malfunctioning 3-way valves with Pressure Independent Control Valves (PICVs), rebalancing hydronic networks, and rewriting BMS staging logic.

Simple payback periods for commercial retrofits typically range from 18 months to 3.5 years, depending on the scope. Fast-payback measures like LED lighting and VFD retrofits often pay back in under 14 months, while major chiller replacements pay back in 3 to 4 years through lower utility bills and eliminated maintenance breakdowns.
