One page descriptions of a technique or action for a given designer, planner, engineer or project manager to take.
Daylighting refers to using natural light to illuminate a building. This controlled admission of natural light into a space through glazing is used to reduce or eliminate electric lighting. By utilizing solar light, daylighting creates a stimulating and productive environment for building occupants.
Strategies to consider include building orientation, shallow floor plates,
increased building perimeter, exterior and interior shading devices, high
performance glazing, and automatic photocell-based controls.
Simple tools and calculations are used in the most preliminary of design concept stages to help determine the viability of daylighting. Simple tools and calculations include:
Physical modeling is another approach to conducting analysis, with the advantage of using real natural light, demonstrating its subtle qualities, and the capacity to represent any room geometry. However:
Today, the trend is toward computer analysis to provide daylighting design information and feedback immediately to the design team. Historically, these tools were sufficiently complex that only researchers involved with product development and/or primary field research were able to use them. Today, however, there are many tools available that have varying levels of complexity in both input required and output obtained. There are free programs available as well as ones for purchase.
