The iconic building in one place in San Francisco is a 12-story commercial structure built at the turn of the last century and survived earthquakes in 1906 and 1989. Therefore, in the view of the city, it is an old building. So it might be surprising that, thanks to an energy retrofit by local engineering firm Carbon Beacon, Flood's 290,000 square feet of building is carbon neutral and boasts energy efficiency and operating costs with a modern efficiency-conscious building. As part of a major renovation of a 350-tenant site, Carbon Beacon used occupancy/light sensing data loggers (ONSET, MA) to determine if energy and money could be saved in the building's toilets. These battery-operated devices can be easily installed in ceilings, light fixtures, and stairwells – whatever the data needs. The UX90-005, UX90-005M, UX90-006, UX90-006M have two integrated sensors, and together they continuously collect real-time data at user-defined intervals. They also feature a large LCD display for visual confirmation of recording work, a signal strength indicator to ensure proper recording position, large storage capacity that can be deployed with less site traffic, and a full-speed USB 2 port Data offload. The bathroom's existing lighting with occupancy sensors is several years old. Carbon Lighthouse first evaluates whether these existing sensors are functioning properly, and then determines whether lighting operation will justify replacement with more efficient equipment. In today's market of constant innovation and new energy efficient products, it seems like a no-brainer to replace all restroom lighting with more energy efficient fixtures. But, as Matt Casse, director of engineering at Carbon Beacon, explains, "In a new build it makes sense to utilize the most energy-efficient systems. But in a retrofit of an older building, you need to approach it differently. .” In commercial buildings like this, there are systems running 7/24, and those systems are often targeted for upgrades. By looking up occupancy first, we can see what real changes are making which will save time and effort. In the case of flooded buildings with toilets, the Carbon Lighthouse team determined that eight would statistically represent the total number of buildings. According to Kaser, it took less than an hour to deploy a palm-sized, battery-operated occupancy/light logger, taken in the field Measurements including ballast, number of bulbs, type, etc. are then collected data loggers leave for three weeks. The data is used by hoboware ®Pro software for logger download and import into your own Carbon Beacon application. "It's easy to do," Kacey said. “We can go from raw data to decision in minutes. The data shows that occupancy rates between 9pm and 7pm and 6pm are significantly less than half of the 24 hours.” Three representative datasets, pp. Two clearly show good occupancy and lighting integration, while the third shows an instance where all lights are on all the time, "according to the data, existing occupancy sensors work successfully to control lighting, with one The room exception. There is no need to spend a fortune to replace occupancy sensors throughout a building. The next step is to calculate whether it makes sense, based on the lighting runtime, to improve the lighting. it doesn't. "Vendors will always want to sell new products, new devices and applications to incentivize more effectively rather than encourage control of existing systems," said Kacey. "Just because a new piece of equipment is more efficient than existing equipment, the cost of replacement may not justify its purchase, especially if you can use aftermarket controls to improve efficiency. You can always replace equipment and reduce power, but it Doesn't always yield enough cost savings. You can make your money bigger elsewhere." UX90-005, UX90-005M, UX90-006, UX90-006M let engineers quantify the actual utilization of space.
