Daylight performance in mid/large buildings: basics, strategies, technologies
(2009-10) Astrich, Bobby; Morris, Alex; Walters, Briana
An examination of the lighting requirements of mid- to large-scale building projects, with a focus on the utilization of natural daylight. The paper considers the sorts of tasks to be performed in different rooms/sections of the building, as well as psychological and biological effects, and discusses strategies for optimizing natural light conditions. Five projects are given as case studies: the Arup Campus in Solihull, England (Arup); World's End School (Architects' Co-Partnership); the Administration Building in Wiesbaden, Germany (Herzog + Partner); the Nasher Gallery in Dallas, TX (Renzo Piano); and the Chelsea Club in London, England (Fletcher Priest).
Daylighting equity : evaluating efforts to daylight lower-income and minority areas in El Cerrito, California
(2018-12-07) Ligons, Sydni Atrice; Paterson, Robert G.
In recent years there has been a push to bring nature and its benefits back into the built environment. Urbanized areas are seeing the revitalization and restoration of once buried urban waterways. This growing trend is known as daylighting and has become an increasingly popular method of bringing nature back to the city. Although nature is making its way back into the built environment, the benefits of nature have been excluded from low-income and minority communities. Park space for the lower income residents has been an issue in the environmental justice arena for years, and in these low-income areas, the lack of green space for the city’s most vulnerable is a problem that has yet to be solved. This report examines urban green planning, daylighting specifically in the City of El Cerrito, California to explore whether daylighting projects present EJ concerns in a California community and the use of analysis tools under the National Environmental Policy Act (NEPA) to explore social justice issues. The PR draws on the California Department of Transportation (CalTrans) desk guide for EJ analysis under NEPA and CEQA (California Environmental Quality Act). That adopts the same definition and criteria of evaluation as NEPA. Smaller regional planning organizations also use this method. Using this evaluation process, I located communities of concern at the census tract and block group level in areas that were not located near daylighting projects in the City of El Cerrito. Although NEPA is primarily used for highway and transportation projects, this report demonstrates the potential of NEPA EJ tools to examine social justice issues for green amenity planning.
Evaluation of lighting conditions in portable classrooms and analysis for alternative daylighting systems
(2016-12) Zhang, Yan, M.S. in Engineering; Novoselac, Atila
Lighting conditions in multiple classrooms in central Texas were assessed, and the feasibility of improving portable classroom daylighting via alternative daylighting systems was also evaluated. Results indicate that surveyed portable classrooms generally provide sufficient levels of light with artificial lighting systems, but have less uniform lighting distribution than permanent classrooms. To evaluate the daylight availability in portable classrooms, a model was developed and verified using field data. Climate-based daylighting simulation was performed using DIVA for Rhino, which uses Radiance and DAYSIM as simulation engines. Results from the annual daylighting analysis suggest that limited amounts of daylight were available in portable classrooms over the course of a year. In order to assess the feasibility of improving portable classroom daylighting conditions, parametric studies were completed to investigate how different factors affect the levels of light in classrooms. Simulation results suggest that increasing window area and higher window placement allow more light into the classroom. Different external shading systems also affect the indoor daylight level. However, the impact of other factors, including building orientation, ceiling-to-floor height, and classroom length-to-width ratio is minimal. While changing the window systems for an existing portable building can require a large construction effort and financial commitment, retrofitting with tubular skylights is a more approachable option. Daylighting analysis shows eight 356-mm (14-inch) diameter tubular skylights can provide the portable classroom with a sufficient light level for more than 60% of occupied hours. When daylighting alone cannot provide sufficient light, lighting control will successfully combine a daylighting system and an artificial lighting system to provide an adequate lighting environment.
