The inclusion of daylight in buildings represents several benefits: its use not only signifies a reduction in the building energy consumption through the compensation of electric lighting, it also has positive effects in the execution of human activities. ...
Data from multiple sensors and actuators has been recorded from December 2001 to March 2008 at the LESO-PB building of the EPFL campus, using the EIB/KNX bus standard. Sensors and actuators provided data on room temperature, presence, lighting level, windo ...
Today, the challenges of sustainable development require revisiting all the parameters of architectural design. According to the International Energy Agency , in 2005, 19% of the electricity produced in the world was consumed for lighting. We know that the ...
The design of a solar protection system that can minimize solar gains while maximizing daylight and view to the outside is particularly challenging in arid climates, such as in the Middle-East, where sand, wind and corrosion impose specific constraints. We ...
We propose a low-cost system for indoor self-localization of mobile devices using modulated LED ceiling lamps that are fully autonomous and broadcast their identifiers without any synchronization. The proposed self-localization method is designed to handle ...
This Recommended Practice conveniently gathers the basic data and techniques which help those concerned with the design of buildings and lighting systems understand and appreciate the opportunities and constraints inherent in daylighting. Daylighted buildi ...
This presentation will explore the multifaceted nature of daylight performance in architectural spaces by discussing ongoing research regarding the dynamics of daylighting performance considering three interpretations of “well-being” in a space: as a human ...
This study presents the results of a monitoring campaign aiming to further our understanding of occupants' behavior regarding the manual control of electric lighting in combination with shading control. It was performed on eight single-occupied offices in ...
High demographic dynamics and greater poverty in developing countries carry the urgent need to provide low cost housing to the poorest in urban regions. In Colombia the development of social housing settlements is characterized by two deficits, a quantitat ...

Total energy consumption by com. and residential buildings in the US nears 40 Quads. Approx. 1/3 of that energy use is due to space heating and cooling. Recent anal. of materials that comprise the building envelope would benefit from smarter windows that m ...
