Prior to making a facility of building green or energy efficient building, one needs to perform an energy audit. However, prior to an energy audit, one needs to ask specific questions to set the proper standards and benchmark for this task.

In identifying these specific questions, a global scan of works and energy audits is necessary. In addition, the reasoning for the energy audit will be necessary. Energy audits are performed for two reasons, the main goal is to simply make the building green regardless of any issues confronting the task, or energy audits are made for economical reasons and simply reduce the cost of the energy consumption of the building.

Interlocked with this analysis is the maintenance costs, age of the building and equipment, capital investment budget allocated, and function of the facility. There are several obvious decision making processes that become evident in the process. If the equipment are aged and due for replacement, if the equipment maintenance costs economically exceed the conventional costs, if the sudden breakdown of equipment for critical facilities causes major havec ion the operation of the space (i.e. hospital patient care), and so on.

Therefore, assuming the energy audit for economic reasons, several pre-curcsers must be met:

• Map of the Campus and identification of the building under energy audit program
• The description of each building:
Age of building
o Number of stories
o Type of construction
o Square foot of building
o Function of the building and critical facility
o Any planned modification
o Period available for major overhaul of equipment
o Position/location of mechanical and electrical equipment
o Description of existing E or B MS (Energy/Building Management Systems)
o Any Electronic or hard copy drawings
o If available: Any commissioning procedures on the building
o If available: Copy of most recent energy audit
o If available: Access the E/BMS Data for upto three years?
o If available: Access to maintenance log to the building upto three years?

• Description of the central plant and location:
o Age of central plant
o Any planned modifications to plant?
o Type of fuel used
o If available: All charts and diagrams correlating the consumption or production of energy (upto three years)
o Any electronic or hard copy drawings
o Description of existing E or B MS (Energy/Building Management Systems)
o If available: Copy of most recent energy audit
o If available: Access the E/BMS Data for upto three years?
o If available: Access to maintenance log to the building upto three years?
