ESD GreenTech is proud to have been part of the sustainability journey of Menara Kementerian Perumahan dan Kerajaan Tempatan (KPKT), Putrajaya, which has achieved the GreenRE Gold Rating under the Existing Non-Residential Building (ENRB) v3.3 category.
The achievement marks an important milestone for KPKT as the first ministry in Malaysia to receive a GreenRE Gold Rating, demonstrating its commitment towards energy efficiency, environmental responsibility and sustainable building management.
What ENRB v3.3 actually assesses
It is worth being precise about which tool this rating was awarded under, because the distinction is not cosmetic.
GreenRE’s new-build tools assess a design. The envelope, the plant, the facade, the water strategy: all of it is still specification at the point of assessment, and the rating reflects what the building is intended to do once it is built and occupied.
The Existing Non-Residential Building (ENRB) tool assesses a building in service. There is no design to improve: the envelope is built, the plant is installed, the occupancy pattern is established. What the assessment examines instead is measured energy performance, documented management policy, operational records, maintenance regime and occupant outcomes. These are the things that only exist once a building has been running long enough to have a history.
In practice that inverts the work. A new-build certification is an exercise in shaping decisions before they are made. An existing-building certification is closer to an audit: establishing what the building genuinely does, locating the evidence for it, and presenting that evidence in the form the assessor needs. It is less about ambition and more about proof.
Gold under that tool, on a 38-storey ministry headquarters, is therefore a statement about how the building is run rather than how it was drawn.
Our role in the certification
ESD GreenTech was engaged to facilitate and manage the GreenRE certification process for Menara KPKT, working closely with Bahagian Khidmat Perunding and the Building Facilities team throughout the assessment.
The exercise involved a comprehensive review of the building’s existing environmental performance and operational practices against the requirements of the GreenRE ENRB v3.3 framework.
Our team coordinated the site assessments, technical reviews, supporting documentation and GreenRE submissions. Close coordination with Bahagian Khidmat Perunding and the Building Facilities team was particularly important in facilitating access to the building, gathering operational information and records, identifying the existing green initiatives already implemented within Menara KPKT, and compiling the supporting evidence the assessment required.
The project was led from the GreenRE consultancy perspective by Ben Ng Kok Kin, GreenRE Accredited Professional, together with the ESD GreenTech project team.
Green features of Menara KPKT
Menara KPKT is a 38-storey office complex with four basement levels, comprising approximately 117,539.73 m² of gross floor area. Despite the scale and operational demands of the building, a range of energy, water, environmental and sustainable management measures have been built into how it runs.
A key energy efficiency feature is the adoption of a District Cooling System. The building records a Building Energy Intensity of approximately 89.9 kWh/m²/year, reflecting its overall energy performance. A solar photovoltaic system contributes approximately 0.26% of the building’s energy consumption.
Water efficiency is a further strength, with 100% water-efficient sanitary fittings provided throughout. Within the basement parking areas, carbon monoxide sensors regulate the mechanical ventilation system according to conditions, keeping ventilation appropriate without running it unnecessarily.
Beyond building systems, Menara KPKT has implemented a number of operational initiatives:
- an Energy Management Policy supporting continuous monitoring and improvement of energy performance;
- a building-wide recycling programme encouraging waste segregation and responsible waste management;
- electric vehicle charging stations supporting the transition to lower-carbon transport;
- convenient access to nearby public bus services;
- bicycle parking facilities;
- annual Indoor Air Quality audits; and
- an environmental education corner promoting awareness of sustainability and green practices among occupants.
Together these measure something design alone cannot: green building performance depends on how a building is operated, maintained, monitored and continuously improved across its lifecycle.
Collaboration towards sustainable building operations
The certification was made possible through close collaboration between KPKT, Bahagian Khidmat Perunding, the Building Facilities team, ESD GreenTech and GreenRE.
Throughout the process, the cooperation of the KPKT teams was instrumental in facilitating the on-site assessment and providing the technical documentation, operational records and supporting information required to demonstrate compliance with the GreenRE criteria.
For ESD GreenTech, the project represents more than a certification rating. It demonstrates how existing large-scale government buildings can enhance and validate their environmental performance through structured assessment, effective facility management and sustained sustainability initiatives.
We are honoured to have supported KPKT in becoming the first ministry in Malaysia to achieve GreenRE Gold certification, and we extend our appreciation to the KPKT team, particularly Bahagian Khidmat Perunding and Building Facilities, for their commitment, cooperation and support throughout the certification journey.
Congratulations to KPKT on a significant green building milestone.
Is your building a candidate?
The question we are asked most often after a project like this is whether an existing building has to be exceptional to be certifiable. In our experience it does not.
A building is usually a stronger candidate than its owner expects if it already has:
- metered energy data going back a year or more. Measured performance is the backbone of an ENRB assessment, and consumption records you already hold are the single most valuable asset in the submission.
- an efficient cooling strategy, however it was arrived at. District cooling, a well-maintained central plant, or a plant that has been recommissioned in recent years. Cooling dominates the energy result in this climate, so a building that has already addressed it starts well ahead.
- sustainability initiatives already running. Recycling, demand-controlled ventilation, air quality monitoring, EV charging. These earn credit, and in most buildings several are already in place without having been recognised as creditable.
- a facility team that keeps records. This matters more than it sounds. Operational evidence cannot be reconstructed after the fact, and a building with disciplined record-keeping is often one short step from certification.
The common gap we find is documentation, not capital expenditure. Buildings that are already well run frequently cannot prove it in the form an assessor requires, which is a far cheaper problem to solve than a plant replacement.
If you are responsible for a government, institutional or commercial building and are weighing this up, the useful first step is a short feasibility review against the relevant tool. It establishes where the building would land today and what it would take to move it, before anyone commits to a target. Tell us about the building and we will look at it.
