In buildings without energy management systems or older systems that need upgrading to perform current strategies an energy audit focused on improved control can reduce energy costs and provide tenant satisfaction. A good energy audit will look at the current control system and where it can be improved on, the cost of the improvements and with analysis of the current energy usage the potential payback.
1) Reduce early start scheduling due to improper morning warm-up sequence.
2) Reduce scheduled occupancy to minimum period of actual occupancy by using occupant override and tenant billing program.
3) Reduce outside air heating and cooling to match the actual occupancy of the building and tenant areas within the building.
4) Improve zone temperature control to avoid simultaneous heating and cooling in adjacent zones.
5) Control common area lighting.
6) Control tenant area lighting.
7) Integrating the temperature control, access control, intrusion alarm and lighting systems to provide automatic scheduling of occupancy.
8) Provide tenant feedback via custom WEB pages on energy usage, temperatures and override periods used to encourage green practices.
9) Sub meter HVAC and electrical energy to provide use billing and return the energy savings to the tenants thus encouraging further reductions.
These and other custom strategies turn your energy management system into a tenant satisfaction system and justify the improvements with paybacks that are typically 2 to 4 years.
