EXTERNAL ENVELOPE


Small skylight openings have the same effect as much larger side windows and can easily illuminate the entire room


Where should daylight enter our buildings?


Natural daylight is therefore the best way to work more productively and healthily, but not all light sources are equally suitable for this. Daylight in any form is superior to artificial light sources, but windows in the wall are often not enough. The setting of your site will be influential on your daylight design strategy. If you are designing on new greenfield land you have lots of scope to design your building and its orientation for


energy efficiency and optimum daylight. However, when working with existing sites, the sky may become more valuable to utilise as a light source. Especially in larger rooms, not enough daylight can penetrate into the depth of the room from the wall. Additionally, we only ever capture part of the sky through wall windows. The University of Roehampton Library project illustrated here is a perfect example of designing for light from above, flooding the room with natural daylight. Even small skylight openings have the same effect as much larger side windows and can easily illuminate the entire room on the top floors or in single-storey buildings. And this is precisely where rooflight solutions demonstrate their efficiency. Bright rooms appear larger – as well as more charming – natural daylight helps us to concentrate, and creates the hormonal basis for a healthy mind and a balanced day-night rhythm. Rooflight professionals will demonstrate how to bring daylight into a design as early as the planning phase, or how to easily retrofit elegant flat roof skylights.
