Efficiency is further optimized because the brake horsepower required is close to connected horsepower and the overall “system effect” is reduced. The building’s cutting-edge tradition continues today: upgrades and retrofits have earned a LEED® Gold certification for the Transamerica Pyramid. The building’s cutting-edge tradition continues today. Transamerica Pyramid — FANWALL ® Retrofit - San Francisco, CA. “We had some difficult space to design in, and everything had to be measured ahead of time to the nearest inch — including height, width, conduit, pipes — so we knew everything would fit.  systems to maintain consistency for acoustical measurement comparison. Case studies illustrate the impact of natural hazards in the short and long term. We had the added advantage of being able to eliminate sound-traps altogether, because the fans operate so quietly.  system and there’s no vibration. We seek to deliver value through targeted development in high-barrier-to-entry locations, or hands-on adaptive reuse projects to increase income and upgrade user experiences. Transamerica companies are part of the Aegon Group. The multiple fans generate the 202,000 cfm required, but the modular design allows individual fan cubes to be navigated through the building and 3-foot doorways and stacked in place. “It was a good option because we could redesign the layout of the cooling coils, fan intake, and ducting at the same time.”, Besides managing the logistics of the retrofit itself, additional goals were efficiency and redundancy. Actual results show that the Transamerica Pyramid reduced electrical consumption by 80,000 kWh, or $25,000 during the first year of operation. Case Study: Transamerica Pyramid Architects William Pereira & Associates chose the pyramid shape not just for its unusual look but also to meet a specific need: a pyramid casts a smaller shadow than a conventional high-rise building, allowing more light to filter to the streets below. Webster contacted Pyramid Center management to discuss the concept as a viable solution. Each. And a recent upgrade to one section of the building’s HVAC system is equally inventive. It went together very simply.”, Initial concerns for general contractor Scott included both sound and vibration, but those concerns abated soon after installation. Instead, AEGON opted to replace the old fan with FANWALL TECHNOLOGY, a modular fan system introduced in 2004 by Huntair, Inc., a Nortek Air Solutions company. That’s positive given that there are tenants on the floors above and below and a data center next door.” The reduced sound and vibration was also verified through an independent study. That means all preparations could be completed while the old fan remained operational, virtually eliminating downtime for tenants. Case Study > Salesforce Tower. The aging air-handler fans serving floors one to 18 of the building required continual maintenance because of their age. Although spare fans and motors were available, delivery lead times were long. The design is counterintuitive from a practical and financial standpoint, since the most desirable upper floors have the least area. The multiple fans and motors provide redundancy in the event of a fan or motor failure, because the remaining operating fans and motors continue to deliver airflow -– and the smaller size and weight of the motors makes replacement easier. AEGON wanted to avoid disrupting tenants while keeping costs within budget. Oldham had found enough space downstream from the original fan, and that’s where new construction occurred. The new fan system supports that philosophy.”, “One of the things that’s really exciting about this project is that it’s 21st century technology,” he added. Air Reps offers distinct advantages in solving challenging problems that often arise in HVAC design and installation projects. The demolition and reconstruction work, completed in three weekends per side, was the responsibility of Kevin Frederick, project manager for the mechanical contractor firm, Anderson, Rowe and Buckley, Inc., San Francisco. ... in case they are used to provide a service that you use.

FANWALL TECHNOLOGY,  produces a uniform piston of air, creating a uniform velocity profile at the unit coils and filters and throughout the airway path in the unit. ft. of floor space, the Transamerica Pyramid requires multiple air handling systems to serve the various zones of the building.
