Abstract:

Actually the issue of daylighting in Architecture, in its technical aspects, is booming due to the increased rates for electricity expenses and the consequent energy saving aim. The best use made of daylight, leads to the lower contribution of artificial light needed and a more sustainable building.

The Spanish Technical Building Code (CTE), Book 10 DB HE Energy Saving, Section 3: Energy Efficiency of Lighting Installations, applied to indoor lighting installations, refers to one of the calculations required to be shown on the project report is maintained average horizontal illuminance on the working plane, which can be formalized either manually or through a computer program.

In this paper a new way to teach the concept of illuminance to architectural students is introduced, making use of a scale model of the place to study, from a theoretical and experimental viewpoint. For that, photometric sensors have been placed in different positions of the model, in order to show students the importance of the proper choice of luminaries considering windows and pillars enclosure.
The procedure outlined is valid for existing, under construction or project enclosures.
