Contingency planning is an affordable, flexible, reliable way to prepare for the worst
In the world of facility management, no one can afford to be caught unprepared in the event of an emergency. Yet the uncertainty of today's economy is forcing many facility managers to tempt fate. Organizations of all sizes are under increasing pressure to cut capital expenses and focus on revenue-generating core competencies. As a result, substantial facility investments are being put on hold, with limited or aging equipment forced to operate for as long as possible in what commonly is referred to as “run-to-fail” mode. For facility managers in such predicaments, there is the cooling contingency plan, an affordable, flexible, and reliable way to prepare for the unexpected.
The cost of developing a cooling contingency plan is minimal compared with the cost of responding to an unplanned cooling failure. For example, in the wake of an emergency, running piping for a 500-ton backup system might cost as much as $5,000 to $20,000. As part of a contingency cooling plan, running that same piping can cost as much as 90-percent less.
Installing hydronic pipes and electrical connections are two measures you will want to take as part of a cooling contingency plan. To those ends:
Determine how a temporary cooling system will tie into the entire infrastructure. Consider not only chilled-water piping, but electrical connections and, if applicable, the condenser-water system.
Dedicate a chilled-water branch to the temporary cooling unit, including shutoff valves and pipe caps.
Understand the electricity needs of a temporary cooling unit. For example, air-cooled chillers use twice as much power as water-cooled ones.
Determine temporary-equipment locations, designate contact personnel, and identify on-site logistical issues.
Mapping details such as these in advance allows you to avoid the panic and overtime costs often associated with unplanned implementation of temporary cooling.
The top three considerations when designing a successful cooling contingency plan are:
Long before the need arises, identify a location that will not only accommodate rental equipment, but provide access to required electrical and mechanical connections.
Include provisions for the commissioning, maintenance, and decommissioning of temporary cooling equipment.
When choosing a supplier, consider three factors: expertise, availability, and flexibility.
Identify suppliers with in-depth knowledge of temporary cooling equipment. If overlooked, even the smallest of details can create major problems during a crisis.
Look for suppliers with experience in application engineering, project management, and service. By selecting a supplier with a wide range of capabilities, you can rest assured your cooling contingency plan will be comprehensive, including a needs assessment, site preparation, installation, setup, commissioning, controls integration, and ongoing maintenance.
When the need for temporary cooling arises, businesses cannot afford delays. Look for suppliers with newer-model, energy-efficient units available for quick delivery.
Lastly, look for a supplier flexible enough to customize rental agreements to meet specific needs.
