Abstract: Residential buildings are responsible for a large share of the total energy consumption. It is well-known that the correct use of natural and artificial lighting can improve energy efficiency. However, lighting in residential buildings should meet other requirements: safety, security, health, comfort, well-being and functional performance. This paper presents an analysis of how these requirements have been incorporated in the Portuguese building regulatory system. The analysis focuses on the regulatory framework, certification systems, incentive programs and awareness initiatives. The main conclusion is that the regulatory system lays down provision mainly on functional performance and energy saving. Lighting requirements regarding safety, security, health, comfort and well-being are often neglected or minimized in regulatory documents. Specialized documents and initiatives present a comprehensive approach. Daylighting design is a challenge, due to its complexity, but has potential rewards. New indicators and methods should be used to lay down lighting requirements, preferably in a separate regulation.
