  1. one or more pressure sensors shall be used to vary pump speed and/or start and stop pumps. The sensor(s) shall either be located near the critical fixture(s) that determine the pressure required, or logic shall be employed that adjusts the setpoint to simulate operation of remote sensor(s).
  2. no device(s) shall be installed for the purpose of reducing the pressure of all of the water supplied by any booster system pump or booster system, except for safety devices.
  3. no booster system pumps shall operate when there is no service water flow.
Elevator systems shall comply with the requirements of this section.
For the luminaires in each elevator cab, not including signals and displays, the sum of the lumens divided by the sum of the watts (as described in Section 9.1.4) shall be no less than 35 lm/W.
Cab ventilation fans for elevators without air conditioning shall not consume over 0.33 W/cfm at maximum speed.
When stopped and unoccupied with doors closed for over 15 minutes, cab interior lighting and ventilation shall be de-energized until required for operation.
Escalators and moving walks shall automatically slow to the minimum permitted speed in accordance with ASME A17.1/CSA B44 or applicable local code when not conveying passengers.
Measurement devices shall be installed at the building site to monitor the energy use of each new building.
Measurement devices shall be installed to monitor the building use of the following types of energy supplied by a utility, energy provider, or plant that is not within the building:
  1. Natural gas
  2. Fuel oil
  3. Propane
  4. Steam
  5. Chilled water
  6. Hot water
The energy use of each building on the building site shall be recorded at a minimum of every 60 minutes and reported at least hourly, daily, monthly, and annually. The system shall be capable of maintaining all data collected for a minimum of 36 months and creating user reports showing at least hourly, daily, monthly, and annual energy consumption and demand.

Exceptions to 10.4.5.1 and 10.4.5.2:

  1. Buildings or additions less than 25,000 ft2
  2. Individual tenant spaces less than 10,000 ft2
  3. Dwelling units
  4. Residential buildings with less than 10,000 ft2 of common area
  5. Fuel used for on-site emergency equipment
