Benchmarks for cleanliness can be subjective. Now that LEED (Leadership in Energy and Environmental Design) standards are gaining a foothold among facilities management and building professionals, there is a benchmark to strive for and a high-quality vacuum is a key part of the equation. LEED is a nationally accepted benchmark and blueprint for building design, construction, renovation and ongoing maintenance. LEED establishes voluntary performance standards and benchmarks for new construction (LEED-NC), for new school facilities (LEED for Schools) and for existing buildings (LEED-EB), among others. The point system for an environmentally friendly existing building falls into five categories: (1) sustainable site planning; (2) green cleaning and maintenance practices; (3) indoor air quality; (4) water and energy efficiency; and (5) system upgrades. Facilities can earn additional points through innovations not listed in LEED, but that still adhere to the overall goals of the program. Schools and universities can use LEED as a guide to achieve cleaning and vacuuming goals.
