5 ISSA Clean Standard: Measuring the Effectiveness of Cleaning the researchers tested surfaces for culturable bacteria using a different method—RODAC plates. The simultaneous testing demonstrated that a reduction in ATP was accompanied by a consistent reduction in culturable bacteria. The researchers, therefore, were able to reasonably conclude that a reduction in ATP suggests both a cleaner and healthier surface. While research has established that cleaning plays a critical role in the quality of the indoor environment, it is well-recognized that there are a number of additional factors that also impact indoor environmental quality. Building maintenance practices such as moisture control, ventilation and air flow, and other factors also play a key role. In addition to health benefits, analysis of existing data supports the position that effective cleaning contributes to the economic bo om line in several ways: 5 • Occupant wellness: reduced absenteeism • Occupant wellness: increased productivity • Asset preservation • Energy savings • Reduced transmission of illnesses 3. Defining Current Cleaning Procedures The implementation of a cleaning effectiveness improvement program involves defining current cleaning procedures and measuring their effectiveness, analyzing the results, considering potential improvements, and then implementing identified improvements. The improvement process is a continuous cycle that requires constant reevaluation. The Clean Standard formalizes this process by inserting the requirement to measure the effectiveness of the cleaning process and ensure an efficient and healthy outcome rather than just a lower initial cost. Toward that end, the first step in the process is to document the current custodial program for the facility, including an inventory of all materials and equipment used, personnel, and the scope of work for cleaning services (including the specific tasks to be performed and the frequency of service). If outside services are employed as part of the regular maintenance program (window washing, service to HVAC equipment, etc.) such services should be included as part of the master schedule for the facility.
