“…In a separate study of automated venetian blinds in the same test rooms, the activation time was varied from 30-s to 5-min and 10-min. Daily lighting energy use increased by 31-43% and 72-86%, respectively, while daily cooling load and peak cooling loads remained unchanged on clear summer days [41]. Separately, some manufacturers may impose surface temperature limits on the electrochromic itself and force "relaxation" or no switching activity to prevent coating damage if these limits are exceeded.…”

“…Therefore, windows directly impact comfort, productivity, and health of the occupants [1][2][3]. At the same time, daylight can significantly reduce buildings electric energy consumption, due to reduction of using artificial lighting [1,4]. This also may decrease internal gains, which reduces the buildings cooling energy demand.…”

Solar and Lighting Transmission through Complex Fenestration Systems of Office Buildings in a Warm and Dry Climate of Chile

et al. 2014

Overheating, glare, and high-energy demand are recurrent problems in office buildings in Santiago, Chile (33°27'S; 70°42'W) during cooling periods. Santiago climate is warm and dry, with high solar radiation and temperature during most of the year. The objective of this paper is to evaluate the thermal and daylighting performance of office buildings transparent faç ades composed of three different complex fenestration systems (CFS). Each CFS contains a different external shading device (ESD): (1) external roller, (2) vertical undulated and perforated screens, and (3) tilted undulated and perforated screens. The study was carried out by in situ monitoring in three office buildings in Santiago, Chile. Buildings were selected from a database of 103 buildings, representing those constructed between 2005 and 2011 in the city. The monitoring consisted of measuring the short wave solar and daylighting transmission through fenestration systemsby means of pyranometers and luxometers, respectively. This paper shows measurements that were carried out during summer period. A good performance is observed in a building with the external roller system. This system-applied to a northwest faç ade-shows a regular and high solar and daylighting control of incoming solar radiation. OPEN ACCESSSustainability 2014, 6 2787The other two ESD systems evidence a general good performance. However, some deficiencies at certain times of the day were detected, suggesting a non-appropriated design.

“…These systems coordinate the control of automated electric lighting and blind systems -which usually operate in isolation-with conventional building energy management systems like heating and cooling units 2,3 . The assumed benefits of this system integration are that it should yield an overall gain in occupant comfort and energy performance over conventional systems 2 while still being "costeffective and practical" 4 . Previous research addressed the technical feasibility of integrated lighting controls 2,3 and their acceptance by the occupants 4 .…”

F.; Voss, K. Monitoring manual control of electric lighting and blindsReinhart, C.F.; Voss, K. NRCC-45701 AbstractThis paper reviews, validates and extends present knowledge of the degree and kind of manual control strategies of blinds and electric lighting systems that are used in private and two-person offices. A new monitoring setup was applied from March to December 2000 in ten daylit offices in Germany that featured manually operated electric lighting and automatically controlled external venetian blinds with manual override. The data shows that individuals consistently followed the same control strategy for their electric lighting and blinds. Groups of individuals tended to activate their electric lighting according to Hunt's probability function although there was a large spread between individual control levels. All subjects used their blinds to avoid direct sunlight above 50Wm -2 and incoming solar
