Begin identifying a target for energy performance. Begin by researching similar building types using the EPA Target Finder program. An Energy Star score of 80 or higher will typically earn EAc1 points.
Sensors must generate an audio or visual alarm to the system operator and if desired, building occupants, if the CO2 concentration in any zone rises above 1,000 ppm or 530 ppm above outdoor ambient CO2 levels, or the lower of the two values.
CO2 sensors must be tested and calibrated at least once every five years, or per the manufacturer’s recommendation, whichever period is shorter. The sensors must have an accuracy of no less than 75 parts per million (ppm) or 5% of the reading, whichever is greater.
Locate a CO2 sensor or sampling location for each natural ventilation zone and each densely occupied space, in order to compare indoor and outdoor ambient concentration levels. CO2 sensors must be located within the breathing zone, which is 3–6 feet above the floor.
Determine whether you need to follow Case 3 for natural ventilation systems. If natural ventilation serves 5% or more of your total occupied square footage, you have to follow Case 3. (You may also have to follow Case 1 or Case 2 in addition—check those requirements.) Rooms smaller than 150 ft2 are also exempt and should not be included in your calculations.
Building staff will also spend time administering the various parking programs: preferred parking, discounted parking, or vehicle-sharing. Procedures and policies for their use must be developed, along with enforcement mechanisms.
Make sure that operations and maintenance personnel (or a vendor, if involved) are set up to maintain the alternative fueling stations. Provide them with all required information about safety and maintenance procedures.
