February 5th, 2010 by Lucas KleschWhich comes first – energy savings or tenant comfort? This is a question we often hear when discussing control strategies. While energy savings and tenant comfort are both important considerations, the good news is that they often are not mutually exclusive. There are many control strategies capable of improving tenant comfort while achieving significatn energy savings. Moreover, the following strategies are relatively easy to understand and can be implemented with almost any type of HVAC system:
- Close OA during night cycle and morning warm up
- Turn fans off at night (unless heating called for)
- Hot/Chilled water temp. reset with respect to OA temp.
- Lock out exhaust fans locked at night
- Reset SA temperature with respect to zone needing most heating/ cooling
- Time clock control of equipment (e.g. boiler, pneumatic air, fans, etc.)
- Economizer cycle
- Optimum start/stop
- Demand Limiting
- Duty Cycle
