Designers of modern building structure need to develop a new approach towards harnessing the attributes of nature and its immediate environment in order to achieve a great level of indoor comfort to the users. The concept of passive design planning and strategies has been known to achieve such thermal performance in building a structure and reducing energy consumption to the barest minimum. The study aims at conducting an assessment on the knowledge level of Architects conducting business in Lagos State of passive design strategies in terminal buildings.
