Horizontal daylighting system for office buildings
Graphical abstract Façade static daylighting system oriented to nonresidential applications. The goal of the project is to save energy by guiding daylight into a building for lighting purpose. With this approach we can reduce the electrical load for artificial lighting, completing it with sustainable energy. The innovative anidolic based collector of the system is integrated on a vertical façade and its distribution guide is always horizontal inside of the false ceiling which includes a series of luminaires.
Highlights High efficiency daylighting system and balanced flux distribution. Collecting matrix system, based on anidolic optical components which minimizes solar incidence dependence. Optimization process that ensures efficient light distribution, maximum uniformity and minimal glare. Lighting level of 300–400lx during the mid-time work hours in an area of 40m2 (4m (wide)×10m (deep)).
Abstract This work is focused on a sunlight collection device for solar lighting systems aimed at non-residential buildings. The design takes advantage of solar energy that reaches the facade of the building for lighting purposes, thereby reducing building energy consumption by supplementing it with clean, renewable energy. This daylighting system's structure comprises a light collector located outside the vertical facade of the building, a modular light guide that runs along the horizontal false ceiling and light extractor luminaires strategically positioned along the guide. The system is configured specifically to the particular characteristics of each building (façade orientation, latitude and longitude) to optimize the global performance. The present paper describes in detail the anidolic collecting system as a part of the comprehensive daylighting system. However the entire daylighting system has been completely developed and experimentally tested, and its prototype is currently integrated into Lledó S.A company's facilities.
