APPENDIX A (Continued)
Complete an economic evaluation for use of heat
recovery machines in large systems. If economically justified,
the large system can be designed for multiple machine
installations by using conventional machines in conjunction with
heat recovery machines. The selection of a double tube bundle
machine is a design function where standby low-grade demand
exists. Where this cannot be justified, use a single tube bundle
machine.

HVAC System Management. Cycling the boiler and
refrigeration chiller in a pattern responsive to the time of day
and prevailing weather conditions reduces energy consumption by
reducing excess heating and cooling capacity during operating
hours. For large buildings, a computerized energy management
system may be justified. These systems can analyze weather
conditions, building and system characteristics, and HVAC
operating conditions. Energy management systems then adjust
various controls to provide optimum energy use.
