High-Rise Energy Recovery System
Lifts brake against gravity. Water falls forty storeys into a valve that destroys the pressure. Chillers reject heat to the sky while water heaters buy it back. HERS captures all three, stores what it cannot use immediately, and produces the measured, auditable evidence your building now has to disclose.
Why now, and why Malaysia
Energy recovery used to be a discretionary sustainability gesture. Between 2024 and 2027 it became a disclosure obligation, a licensing condition, a tariff exposure and a financing variable — all at once.
Malaysia's National Sustainability Reporting Framework phases ISSB-aligned reporting into Bursa-listed issuers. Scope 1 and Scope 2 emissions are required from each group's first reporting period; Scope 3 follows in the third year. Landlord common-area electricity is Scope 2 for the owner and Scope 3 for every tenant in the building.
Group 1 FY2025 · Group 2 FY2026 · Group 3 FY2027In force since 1 January 2025. Any consumer above 21,600 GJ (≈6,000 MWh) in twelve consecutive months must appoint a Registered Energy Manager, run an energy management system and submit efficiency reports. Office buildings from 8,000 m² GFA must carry an energy intensity label.
In force · Suruhanjaya TenagaSince 1 July 2025 the non-domestic bill is unbundled. Medium Voltage General carries a capacity charge of RM29.43/kW and a network charge of RM59.84/kW of maximum demand — RM89.27 per kW per month before a single kilowatt-hour is billed. Demand is now the dominant line item.
Effective to 31 Dec 2027GITA Asset gives a 60% allowance on qualifying capital expenditure, set off against up to 70% of statutory income. GTFS 4.0 adds a 1.5% p.a. financing rebate with a 60–80% government guarantee. Certified green assets also price better in SRI sukuk and sustainability-linked facilities.

Each section below stands on its own. If you only read one, read the reference case — every figure on this site comes from it, and the assumptions behind them are published alongside.
Why three small recovery streams become significant once they share a bus, and why under RP4 the timing of a kilowatt matters more than the kilowatt.
