HVAC Case Study
Porsche Centre
Malaysian automotive workshop and showroom exceeding expectations by choosing evaporative cooling over air conditioning
Located in the city center of Kuala Lumpur, Porsche Centre Sungai Besi is constructed on a 1.25 acre plot of land, with a built-up area of approximately 3,324 square meters. The 3s Porsche Centre Sg Besi is equipped with state-of-the-art sales gallery, parts and after sales service. The sales gallery has a capacity of displaying up to 18 cars, showcasing the latest Porsche models and a wide selection of pre-owned vehicles while the workshop houses 9 service work bays.
The Problem
As an effort to improve the thermal comfort in the workshop, an independent environmental study was commissioned by Sime Darby Auto Performance. The study revealed that the daytime temperature in occupied areas of the workshop routinely exceeds 32°C, and the 650 square meters’ workshop in the Porsche Centre Sg Besi is under-ventilated. High radiant temperature of the workshop’s surroundings (roads, roofs and dark cladding of the building) ruled out the use of a mechanical ventilation to maintain a reasonable working condition.
The study recommended to adopt measures to improve the thermal comfort, which included increasing the air velocity with big ceiling fans, installation of additional louvers, and also air conditioning the workshop.
The option of Air Conditioning was excluded due to the high initial investment and high running costs. Workshop doors would have to be replaced with expensive high speed roller shutters to retain the cool air inside. In addition the high energy consumption resulting in high running cost combined with the environmental unfriendly aspect is also why air conditioning was not an option.
