The Hilton @ Sandestin Beach Golf Resort & Spa, located in Destin, Fla.,along Florida’s northwest Gulf Coast between Pensacola and Panama City, features 600 guest suites, 32,000 sq. ft. of meeting space, four on-site restaurants, four championship golf courses, 13 tennis courts, two outdoor and one indoor swimming pool, and a full-service spa, salon and fitness center.
In the world of fire suppression technology, the sophistication of fire detectors and control panels and the sustainability of fire extinguishing agents are currently topping the list of recent technological advancements. “If a detector senses a fire and creates an alarm, the panel can not only tell that a potential fire exists, it can also indicate when, where and how big, and it also tracks the history of the event,” explains Joseph Behnke, manager of technical services engineered systems for Tyco Safety Product’s fire suppression business, Marinette, Wis. Not only that, but the latest control panels are not only faster and smaller, but they offer increased monitoring ability with graphic displays and text messages, according to David N. Holst, department manager for plumbing and fire protection systems, Bala Consulting Engineers, Philadelphia. “These panels offer more programming and connectivity options so that the extinguishing systems for multiple rooms, buildings or even locations can all report to one central panel,” explains Holst. With regards to clean agents, Jeff LaSalle, P.E., chief fire protection engineer for EwingCole, Philadelphia, explains that the phasing out of Halon 1301 has resulted in a significant increase in the number of viable alternatives. “As a number of these agents are considered to be quite sustainable, this gives the facility owner or manager the peace of mind that he or she will only have to purchase the system once, eliminating a costly retrofit due to future environmental restrictions,” says Behnke. At the same time, LaSalle points out that the increased number of agents can sometimes be confusing, but it is a small price to pay for providing engineers, designers and owners with more options. Elsewhere on the fire suppression new technology front, special purpose sprinkler heads and heads that provide greater coverage are being developed, says Holst. And while it is pretty hard to improve on the technology of pipe, there is a continuing attempt to make it stronger, lighter and cheaper, he adds.
Mesa Public School District #4 is the largest school district in the state of Arizona. It boasts over 70,000 students in over 100 campuses scattered over 200 square miles. Because of rapid growth, Mesa Schools, like many other districts across the nation, were forced to utilize modular classrooms for two reasons.
A school district’s biggest expense after payroll is its utility bill. Because the HVAC system is a major component of a school’s utility bill, careful evaluation of a school’s HVAC requirements and equipment options can help administrators save money while actually improving learning productivity. Every school is different, so there is no one HVAC solution for all schools. Instead, there is a “best” solution for each individual school—chosen from careful evaluation—that maintains the highest possible indoor air quality at the lowest possible energy costs.
