(6) Prepare initial sketches of any readily identifiable changes which must be made to the
existing mechanical or electrical systems.
(7)
Determine the source and type of heating and cooling for each building.
(8)
Verify data gathered to calculate heat loss and the cooling load of each building.
(9)
Verify the existence and condition of economizer capabilities for each major air system.
(10) Identify local loop controls or devices which are in need of repair or replacement.
(11) Develop an input/output (I/O) point estimate. This is a function of the degree of control
required, types of systems to be monitored, and the selected application programs. The I/O point count
will have a direct impact on the system cost.
(12) Develop a preliminary list of required application programs. Commonly used programs
include:
(a)
Scheduled start/stop.
(b)
Steam boiler selection.
(c)
Optimum start/stop.
(d)
Hot water boiler selection.
(e)
Hot water outside air reset.
(f)
Lighting control.
(g)
Demand limiting.
(h)
Chiller selection.
(i)
Day/night setback.
(j)
Chilled water reset.
(k)
Economizer.
(l)
Condenser water reset.
(m) Chiller demand limit.
(n)
Ventilation/recirculation.
(o)
Hot/cold deck reset.
(p)
Remote boiler monitoring control.
(q)
Reheat coil reset.
Specific requirements for the design survey are covered in Appendix D, DESIGN SURVEY
PROCEDURES. Included in Appendices C and D are survey data forms. These forms are intended for
use during the survey to record data for use in the subsequent analyses.
