It seems as if there aren't a lot of building owners out there who went through the Boy Scout program. If they were Scouts and they read the manual, they would know the motto: "Be prepared."
As a building owner, being prepared means having a contingency plan ready to implement in case things go wrong. For example, what would happen if a building's heating, ventilation, or air conditioning system were to break down for an extended period of time? In an office building, it would mean that tenants might have to leave due to uncomfortable temperatures. But in critical applications, such as computer rooms, laboratories, or health care facilities, it could be hazardous to be without part or all of the HVAC system.
