Project Requirements

Describe team goals here.

Design

To begin, the main components of the building will be inspected to yield the required information to perform an efficiency analysis. Most of this information could be gathered from the manufacturer and/or the equipment operator.

Boilers

BoilerW Information required:

  • BTU Output (BTUW)
  • Maximum Load Efficiency
  • Service Area (volume, heating requirement)
  • Type of Fuel
  • Cost of Fuel
  • Type of Boiler Control (manual, automatic)
  • Auxiliary Equipment Used
  • End-Use Devices (specifically control methods)
  • Placement of Control devices (ie. temperature sensors)
  • Automated Control Schedules
  • Average Usage
  • Turndown Ratio
  • Boiler System Dampers
  • Steam Traps (if used)

(Information)

Burner and Fan System

Information required:

  • Cleaning and Maintenance Schedule
  • Type of Burning Unit
  • Type of Fan Motors

(Information)

Chillers

Chilling unit information required:

  • Chiller Type
  • Cooling Capacity (BTU/Hr)
  • Operating Schedule
  • Auxiliary Equipment (types, control, age)
  • Typical Usage (seasonal, etc.)
  • Chiller Controls (manual, automatic)
  • Control Sensors (type and location)
  • Pump Usage/Type (flow, pressure requirements)
  • Sump Heaters
  • Standard Chilled Water Temperature
  • Heat Rejection Fans
  • Minimum Condenser Temperature Limit
  • Maintenance Schedule (level of fouling, cleaning)
  • End-Use Devices (pressure requirements)
  • Refrigerant Charge Limits
  • Purge Units
  • Valve Types

(Equipment and Operation Guide, Pumps, Compressors, Refrigerant)

Note: Cooling storage methods may provide a means to reduce electricity consumption by utilizing cheaper electricity rate periods. These systems are often expensive, suggesting that the cost and long-term savings benefits be weighed against the disadvantages.

Service Water Consumption

Information required:

General:

  • Average water usage
  • Average number of users
  • Pumps (required, type, flow and pressure requirements, manufacturer)
  • Existence of gravity tanks

Water Heater(s):

  • Type of heater
  • Temperature requirements
  • Hot water capacity
  • Recirculation pumps (size, manufacturer)
  • Level of insulation
  • Maintenance and cleaning schedule

Taps/Faucets/Wash Basins:

  • Number installed
  • Type (manufacturer, age, design type)
  • Maintenance schedule
  • Faucet aerators
  • Soap dispensers (type, location, quantity)

Toilets and Urinals:

  • Quantity
  • Type (manufacturer, age, design)
  • Maintenance schedule

Shower Facilities (if required):

  • Quantity
  • Number of uses per shower head per day
  • Faucet Type
  • Existence of water conservation instructions
