The City of Zürich’s stream daylighting policy has long received the attention of researchers [1] and is considered by some to be unique in the world. [14] It had been adopted since 1986 and ensued in daylighting nearly 21 kilometers of Zürich’s buried streams thus far.
Active daylighting is a system of collecting sunlight using a mechanical device to increase the efficiency of light collection for a given lighting purpose. Active daylighting systems are different from passive daylighting systems in that passive systems are stationary and do not actively follow or track the sun. [ 32 ]
These greater environmental systems include the watershed, bioregion, and ultimately, of the planet, as well as human social systems such as local, regional, national and world economic, governmental, and cultural exchange systems. Biometrics is central to the Ecocity concept through the analogy of the cities as living organisms. Cities ...
Daylighting can refer to: Daylighting (architecture), use of windows for indirect lighting; Daylighting (intersections), improving road visibility at intersections; Daylighting (streams), restoration of a previously buried watercourse; Daylighting (tunnels), opening a transportation tunnel
Cities around the world, including Amsterdam, Toronto, Seoul as well as many across the U.S., have launched actions to protect water systems, but the latest climate emergencies show that even more ...
Scott governs one of the nation’s oldest water systems in the U.S. and recently led Baltimore through a short-lived emergency involving E. coli contamination in the city’s water.
There is an incremental cost to daylight harvesting systems. Dividing this cost by the annual energy savings provides a "simple payback", the number of years for the system to pay for itself. [19] The shorter the calculated payback period, the more likely it is that a building owner will invest in the system. Costs vary for a whole host of ...
The website 24/7 Wall St. examined the quality of water supplies in most major America cities, using data collected from multiple sources for five years (ending in 2009) by Environmental Working ...
