Project Overview

This 241,000 SF building is a high-rise located in the heart of downtown Sacramento.  It consists of twelve floors of occupied space with two levels of subterranean parking garage space (64,500 SF).

Mechanical Highlights

  • The building is designed to take advantage of energy saving building products such as low-e glass, superior insulation, and many mechanical features listed below. 
  • The state-of-the-art Building Automation System (BAS) supports open protocols and provides complete control of all mechanical systems and lighting.  The BAS allows every building tenant control of their respective HVAC and lighting via the internet.
  • A life cycle analysis of mechanical system enhancements was performed by FMB’s engineering staff to quantify economic payback times.  Each system enhancement was then utilized if payback was three years or less, and considered if less than five years. 
    • Fan powered terminal boxes to utilize return air for increased ventilation and more efficient re-heat temperatures.
    • High efficiency chillers with lower KW/ton ratios.
    • Variable frequency drives on pumps, fans and chillers to optimize pumping horsepower requirements.
    • Pre-cooling of raw outside air with indirect evaporative cooling.
    • Low NOx boilers with condensing exhaust streams.
    • Dual duct air delivery.
    • Variable frequency drives on domestic water supply pump.
    • Carbon monoxide monitoring to control garage exhaust capacity.
    • Carbon dioxide monitoring of return air to optimize outside air quantities for better energy usage and increased indoor air quality.
    • High efficiency glazing systems that reduce solar gain.
