Power Savings – BAS – Case Study

Environment: Retail with multiple floors and zones.
Customer thinks their system is wasting too much power (BAS system).
Customer complains the external lights are schedule with no control internally.
Customer thinks a new BAS could fix their problems.
Current BAS was too slow to be efficient.
Customer also wants to add control to various zones to monitor, trend and control.

Hvac systems are stabilizing zone temps with 1-2’F.
Hvac Main systems are heating and cooling at the same time.
Found internal lighting systems connected with no logic installed or programmed.
Zones are not efficient for proper control of environment or power management.
Control interface was outdated with all renovations within the last 10 years.
Current programming in all devices were outdated and not efficient.
Found communication lines of BAS were not correctly terminated and came loose as well as some places not even connected.
Cooling plant programming was outdated and mixed in with logic and devices no longer on site.
Verified current BAS system can meet the needs of the customer and expand when needed, no need to replace the current BAS.

Fixed all logic to stop the heating and cooling during the same cycle while able to maintain the zone temperature set points.
Reconnected all internal lighting points with correct logic programmed into all devices to work with current hardware.
Re-zoned all internal areas and control points to make efficient with all the changes of renovations throughout the years.
Updated all the control interfaces for the Customer with upper management in mind.
Updated all logic through the building to handle the current and future needs of the system.
Re-Terminated all BAS communication lines to All devices – found more comm. line issues and corrected.
Updated Cooling Plant to reflect current onsite changes as well as updated all programming logic to the current standards of today.
Added another workstation to handle multiple user input while keeping efficiently on top.
Added more monitoring and control points to system as Customer wanted.

After 6 months the Customer agreed they are already saving 23% of energy.
Didn’t have to change out the current BAS thus saving the Customer a lot more money.
Was able to improve the air control inside the building while saving energy.
Lighting is now correctly scheduled (inside and outside) with correct zoning.
All programming is now up to today standards and bulletproof, leaving the Customer able to rely on the BAS.
