Today the highly glazed façade has almost become an iconic element for a "green building" that provides daylighting and a visual connection with the natural environment. Even before the current interest in green buildings there was no shortage of highly glazed building designs. But many of these buildings either rejected sunlight, and some associated daylight and view with highly reflective glazings or used highly transmissive glass and encountered serious internal comfort problems that could only be overcome with large HVAC systems, resulting in significant energy, cost and environmental penalties.</p>1 aSelkowitz, Stephen, E.1 aAschehoug, Øyvind1 aLee, Eleanor, S.  uhttps://facades.lbl.gov/publications/advanced-interactive-fa-ades-critical02057nas a2200133   4500008003900000245009300039210007000132260007700202520149400279100002701773700002101800700002301821856007901844       2003                          d00aPerspectives on Advanced Façades with Dynamic Glazings and Integrated Lighting Controls0 aPerspectives on Advanced Façades with Dynamic Glazings and Integ  aEcole Polytechnique Federale de Lausanne, Lausanne, Switzerlandc10/20033 a<p>There is growing interest in North America on the subject of highly glazed building façades. The concept of a smart, interactive façade is not new – the ability of specific façade systems to work reliably and effectively is a far greater challenge. We have been exploring various dynamic façade systems with integrated lighting and HVAC over the last 10 years. These include automated blind systems as well as emerging electrochromic glazings, both with automated dimmable lighting and smart controls. More recently we have extended this work to include internet-based control of lights, blinds and glazings using low cost chips embedded in fixtures, motors, and glazing controls. As each window and lighting element becomes a node on the internet they can be controlled via the existing building energy management system either from an occupants desktop computer, an on-site facility manager or even from a remote location. Recent experience in California with disruptions in electric supply and costly peak power suggest value for such capabilities. This paper briefly summaries the state of recent work in this field, describing a new facility with three side-by-side test rooms in Berkeley to test new electrochromic window prototypes, and identifies key performance, systems integration and cost issues now being studied. The authors bring a cross section of both North American and European experience to address the many technology, design and business issues involved.</p>1 aSelkowitz, Stephen, E.1 aLee, Eleanor, S.1 aAschehoug, Øyvind  uhttps://facades.lbl.gov/publications/perspectives-advanced-fa-ades-dynamic00811nam a2200241   4500008004100000050001500041245007900056210006900135100001600204700002300220700001900243700002500262700002000287700001700307700002000324700003000344700002000374700002100394700002000415700002800435700002700463856007900490       2001                        eng d  aLBNL-4749300aDaylight in Buildings.
