The property manager's goal was to implement low-cost/no-cost Energy Conservation Measures (ECMs) by utilizing the expertise of an energy reduction consultant, Ridgecrest Energy Advisors, that specializes in identifying and implementing such measures. While our building has been well-maintained and operated, Ridgecrest was able to:
-- Implement sophisticated programming of our existing energy management control system to optimize operations while eliminating waste associated with systems. This required installation of select temperature and relative humidity sensors for use in polling current conditions used for making instantaneous adjustments to setpoints without compromising comfort or indoor air quality.
-- Optimize central cooling and heating systems by temperature resets, equipment staging, and optimized system pump control.
-- Institute a campaign encouraged employees to turn off lights, TVs, and equipment when they are not required.
-- Identify and repair or replace faulty controls that were affecting performance as well as efficiency.
-- Retrofit existing pole-mounted metal halide lighting fixtures at parking lots to LED fixtures; replace some fluorescent lay-in fixtures at corridor ceilings with new LED fixtures; and install occupancy sensor lighting controls.
-- Enhance control of the air distribution systems throughout the facility. This was achieved by utilizing the existing Building Automation System (BAS) to establish temperature setpoints and allowable temperature ranges throughout the facility. Local control within a pre-programmed temperature range was provided except at public spaces where setpoints were fixed at the BAS. The result was more uniform temperatures throughout and reduction in comfort-related complaints.
-- Since not all areas in a hospital are used 24/7, zone temperature setback schedules were programmed to minimize HVAC costs in unoccupied areas. Thermostats are equipped with “override” buttons to allow for unexpected afterhours HVAC. A primary source of energy savings was greatly reducing the amount of cooling and then re-heating of supply air from Air Handling Units (AHUs) throughout the year by automated supply air temperature reset based on current demand. Simultaneous heating and cooling was eliminated at units equipped with pre-heating coils and chilled water coils.
-- Utilize existing Variable Frequency Drives (VFDs) on fans/pumps by automatically resetting static pressure/differential pressure setpoints based on instantaneous demand.
-- Huge savings resulted in ‘shoulder months’ by optimizing “free cooling” economizer control at AHUs.
