Half Day Talk on “Conceptual Design: An Energy Efficient Approach to Design Centralized Air-Conditioning VRV System for Commercial Buildings”


(Co-organised with Daikin Malaysia Sales & Service Sdn. Bhd.)


Date              :      Thursday, 27 June 2024

Time             :      9:00 a.m. – 1:00 p.m.

Venue           :      Capri by Fraser, Menara Tiga Serangkai, Jalan Tengku Azizah, Kim Teng Park, 80300 Johor Bahru, Johor.

Speaker        :      Ts. Teoh Sun Jie, Manager of Application Engineering at Daikin Malaysia Sales & Service Sdn. Bhd.



To align with SDG 7 (Affordable and Clean Energy), and SDG 13 (Climate Action), optimizing energy utilization in a commercial building is important, especially since the air-conditioning system consumes more than 50% of the total building electrical load. Often, designers use equipment’s rated power consumption or coefficient of performance (COP) to design an energy-efficient building but overlook some factors that could affect the equipment's efficiency. In this presentation, these factors will be discussed, along with the suitability of centralized air-conditioning systems, such as VRV systems, for commercial buildings. Additionally, a proposal for a structural change to the building will be presented, which could potentially improve efficienc y of the air-conditioning system.
