The aim of this study is to evaluate shading performance and the extent of sunlight penetration on the front house facade of the earliest terraced houses in Malaysia built in 1950s. Two house facades are selected for the case study located in Petaling Jaya Old Town, the first Garden City’s new town in Malaysia. The survey applies sunlight simulation technique using the SunTool programme. The simulation calculates at hourly interval from 7.00am to 6.00pm. The study finds that terraced house facades built in 1950s do not sufficiently design to tackle the house facade exposed to direct sunlight. The emphasis of façade design built in 1950s is more on the architectural style rather than designing efficient shading devices to tackle direct sunlight penetrating to the façade wall and windows. Roof overhang and recessed wall with balcony are the horizontal shading elements commonly used in the house façade design. No vertical shading device was applied to the façade design during 1950s.
