Suck it Up

Schools and universities can use LEED as a guide to achieve cleaning and vacuuming goals.
Because LEED-EB requires a high level of capture and containment of particulates, education institutions may want to consider a HEPA vacuum. Vacuums certified as “True HEPA” have been specially sealed and independently tested for leakage. These are designed mainly for asbestos cleanup, healthcare and clean-room settings. But a well-engineered HEPA machine is quite capable of excellent pollutant capture.
Look for a model with a strong motor that creates good static lift (around 100 inches) and 150 cubic feet per minute of airflow. If the manufacturer does not state that its HEPA vacuum captures 99.97 percent of particles 0.3 micron or more, then don't buy it.
Capture rates are important, but comfort and efficiency for cleaning staff also are critical. Two studies by the Ohio State University Department of Surgery Division of Orthopedics and the Battelle Memorial Institute determined that the ease of use and ergonomic design of backpack vacuums enabled workers to vacuum more than twice the area in half the time. This increase in productivity took less than half the energy and effort it would to clean the same area with an upright.
High-quality body construction is essential for a LEED vacuum. An upright with a beater bar and fabric bag housing the filter can be ill-equipped for effective dust capture. It tends to churn more dust into the air than better built machines. Look for a sturdy backpack or canister with a lifetime guarantee on molded body part replacement. Durability will save money and improve performance in the long run, especially on repairs, because daily vacuuming is required in high-traffic areas such as hallways, building entrances, classrooms and elevators.
LEED standards and guidelines have enabled schools and universities to create detailed cleaning programs with specific goals in mind — and with the right vacuum, certification can be an attainable goal.

LEED's Indoor Environmental Quality Green Cleaning Credit 3.7 covering sustainable cleaning equipment outlines specifications and initiatives to receive this credit:
-
Establish a program for the use of janitorial equipment that reduces building contaminants and minimizes environmental impact.
-
Vacuum cleaners should meet the requirements of the Carpet and Rug Institute (CRI) “Green Label” Testing Program and operate with a sound level less than 70dB.
-
Use ergonomic power equipment designed to minimize vibration, noise and user fatigue.
-
Keep a log for each type of housekeeping equipment, and document the purchase date, repair and maintenance activities, and vendor specification sheets.
