ZERO Carbon City Workshop with C40

IEN had the pleasure of presenting our low-carbon building recommendations report to the city council of Kuala Lumpur and other cities in the region at this C40 workshop on Building Decarbonization. Our report focused on the energy consumption, commuting energy and embodied carbon of office buildings and apartment buildings.

Over the last six months, we managed to collect a full database with detailed building information for:

  • 40 office buildings with 40 different building parameters

  • 21 residential apartment buildings with 35 different building parameters

Working with Dr. Nofri Yenita Dahlan and her team at UiTM, we used multiple regression analysis to establish Energy Use Intensity, EUI (kWh/m2/year), formulas and calculators for both office buildings and residential apartment buildings.

On a 50-year timescale, we listed out the submissions that the city council should request for, both during the planning and building plan submission approval process, but also during the operational phase of the building:

Recommended submissions to DBKL to ensure low-carbon buildings throughout their lifetime

We proposed a list of mandatory prescriptive building performance parameters to met by the submitting parties to the city council. We also proposed progressively more stringent requirements to be met by 2025, by 2030 and by 2035. Hereby, the city council can send a clear signal of its low-carbon building trajectory to the developers. And a consequence, some developers may choose to design to meet the future more stringent design requirements, as a way of future-proofing their developments.

We also conducted a comprehensive stakeholder analysis on the topic of how Kuala Lumpur can transition to becoming a zero-carbon city. Frequent stakeholder responses included:

  • Mandatory energy performance requirements for buildings

  • Mandatory annual building performance reporting

  • Economic incentives for enabling the zero-carbon transition

From the National Low Carbon Cities Masterplan, the capital city of Kuala Lumpur is placed in the group of Malaysian cities that first will become carbon neutral, namely by 2050:

As such, Kuala Lumpur, a C40 city, is becoming a de facto role model city for the transition to zero-carbon. We look forward to continuous collaboration with the city council and C40 in the zero-carbon transition quest that requires bold and imminent action.
