These plants and gravel replaced grass, bushes and flowers, which require more irrigation. replaced with conventional type cooling towers with a variable frequency drive (VFD) on each cooling tower fan in 2004. A conventional type cooling tower is more efficient than a fanless cooling tower, which requires a good deal of pumping pressure to evaporate the cooling tower water. Although a conventional type cooling tower requires additional fan energy to evaporate the cooling tower water, this energy is considerably less than the extra pumping energy required with a fanless cooling tower. To reduce water use, the owner has installed low-flow plumbing fixtures and a zero-discharge cooling tower treatment system, which is expected to save approximately 64 362,000 gallons of tower blowdown water per year. The pneumatic control system is original to the building. Over time, the penthouse equipment was converted to direct digital control (DDC), but the space controls have remained pneumatic. Plans call for replacing the original pneumatic controls with DDC, to upgrade the penthouse controls to the new DDC system and to implement an energy management system to accommodate advanced HVAC control strategies and precisely monitor the system. Golden Hill’s owner pursued LEED for Existing Buildings (LEED-EB) certification in 2008 to improve the facility’s existing performance and to set a prescribed standard for sustainable operations and maintenance, and future renovations. fa l l 2 0 1 1 general Contractor sand Construction (for tenant finish work) mechanical engineer rick osbaugh, P leed AP The rmH group .e., , electrical engineer mike Watkins, P .e., leed AP The rmH group , energy modeler Jessie Jones, leed AP o+m, The rmH group environmental Consultant dave stuart, stuart environmental lighting design mark rudiger, iesnA, leed AP The rmH group , leed Consultant Jessie Jones, leed AP o+m, The rmH group As part of the LEED-EB effort, Golden Hill’s mechanical systems were recommissioned to fine-tune performance.
