Booster pumps elevate water pressure and flow in plumbing systems and help in meeting the water requirements of larger facilities. Packaged booster pump systems help large facilities meet the unique pressure and flow demands required of their plumbing fixtures, specialized plumbing equipment, irrigation systems, and HVAC equipment. The booster pump moves booster pump moves building's water source to the plumbing distribution system by increasing the water pressure. A booster pump is required by code when the water pressure from the local water source is unable to meet the required flow pressures at the fixtures. It is expected that booster pumps will become more common in residential buildings and to increase in size due to increased pressure requirements. It is also expected that critical and institutional facilities will require commissioning on all booster pump installations. Source

Experts suggest that significant benefits can be realized from properly designed rainwater harvesting systems. They suggest that such alternative water source systems (AWSS) need to be designed and sized by design professionals possessing either a Certified in Plumbing Design CPD) certification from the American Society of Plumbing Engineers (ASPE) or a Professional Engineer (PE) license. The roof is a critical component of the rainwater harvesting system and will define some of the other system components, such as filtration. Recommended roofing materials to achieve these objectives include standing seam metal, ethylene propylene diene monomer (EDPM), and slate or tile. The rainfall rate used for designing roof drainage systems is also related to the average frequency of occurrence and the time that it takes runoff to reach the collection device from the most remote portion of the contributing roof area.

Building systems data can be used to manage equipment operations and determine how to run the building more efficiently. Owners of a multitenant building may install meters in each leased space to determine how much energy is being consumed per tenant. Metering energy use will provide the information operators need to make informed decisions and provides essential information to the commissioning agent when recommissioning or retro-commissioning a building. Green rating systems, such as the U.S. Green Building Council's LEED program, recognize the essential role of meters as a feedback mechanism for the operation and maintenance of a building, and they award points for carrying out a proper measurement and verification (M&V) plan, which may include realtime energy metering. The most common standard used for M&V is the International Performance Measurement and Verification Protocol (IPMVP), available from the Efficiency Valuation Organization. Source

Benchmarking, an energy performance comparison, can boost energy efficiency and lower building operating costs. Benchmarking involves measuring and rating a building by comparing it to a standard. Some owners and managers collect energy data for their entire portfolio of buildings, calculate the energy use intensity (EUI), which is energy consumed per square foot, and then choose a baseline as the year with the highest consumption. One of the most widely used energy benchmarking systems in the United States is Energy Star Portfolio Manager, a free Web-based tool maintained by the U.S. Environmental Protection Agency (EPA). Users input basic building parameters, such as space type, square footage, hours of operation, number of occupants, and number of personal computers (PCs), as well as 12 months of total energy data. The National Institute of Building Sciences is establishing a High-Performance Building Data Collection Initiative to determine a methodology for collecting and disseminating energy and building attribute data.

Chicago's new 30,000-sq-ft Ping Tom Memorial Park Fieldhouse, designed by Wight & Company and MEP engineering firm, Environmental Systems Design (ESD), maintains a lean energy profile to serve local resident. The design, its LEED Gold-status pending, features high efficiency lighting, distributed WiFi, HVAC systems connected to a geothermal well field, and amenities including a gymnasium, clubroom, full-size competition pool, zero depth pool, and fitness rooms. Key systems include a vertical borehole geothermal system with high-efficiency modular heat pumps, high-efficiency condensing boilers coupled with low temperature hot water distribution, a refrigerant heat recovery system in the pool air handler, air-to-air heat recovery serving the large locker rooms, and a rainwater harvesting system. The hydronic system has 25% propylene glycol to allow for year-round operation and diminish freezing potential. Geothermal water distribution is connected to modular heat pumps located in each room or zone throughout the fieldhouse. Source
