Abstract
This article discusses the performance of a new skylight for standard classrooms at the Egebjerg School (Denmark), which was built ca. 1970. This building underwent important reforms under a European project to which the authors contributed. This research aimed to create a new skylight prototype that is useful for several schools in the vicinity, since there is a lack of educational facilities. The former skylights consisted of plastic pyramids that presented serious disadvantages in terms of sustainability matters. During the design process, the priority changed to studying the factors that correlate daylighting with energy and other environmental aspects in a holistic and evocative approach. Accordingly, the new skylight features promote the admittance and diffusion of solar energy through adroit guidance systems. In order to simulate different scenarios, we employed our own simulation tool, Diana X. This research-oriented software works with the effects of direct solar energy that are mostly avoided in conventional programs. By virtue of Lambert’s reciprocity theorem, our procedure, which was based on innovative equations of radiative transfer, converts the energy received by diffusive surfaces into luminous exitance for all types of architectural elements. Upon completion of the skylights, we recorded onsite measurements, which roughly coincided with the simulation data. Thus, conditions throughout the year improved.

Summary
The Model Educational Buildings for Integrated Energy Efficient Design (MEDUCA) Project for the Commission of European Communities proposed the renovation of some relevant educational facilities in Denmark These buildings were inadequate as a consequence of the natural passing of time, and of the demands resulting from increased migration from the neighboring country of Germany. The authors collaborated to predict the effects and results of a new type of skylight on the luminous and thermal performance of a typical classroom in Egebjerg School, which is located in the municipality of Ballerup (Copenhagen, Denmark) This public school, which was built in the 1970s, went through a core refurbishment within the framework of the said project (cofunded by the EU Directorate XVII for Energy (Thermie Program)).
