The SAP runs from 1 to 100+, with dwellings that have SAP>100 being net exporters of energy. SAP 2012 has been used as the basis for checking new dwellings for compliance with building regulations in the United Kingdom requiring the conservation of fuel and power since 6 April 2014 in England or 31 July 2014 in Wales.
Monitoring of occupied BASIX single dwellings conducted by Sydney Water confirmed that the actual water savings were 40.6% in 2008 and 37.6% in 2009. [6] BASIX has won a number of awards in Australia, the most recent one being in 2007 for "Energy in Society - For contributing to policy, law and the community" at the Australian Institute of Energy.

Basically NHER measure the energy efficiency of dwellings as a function of energy cost per square meter. The energy usage is calculated by considering the all aspects of buildings (location, design, construction, water heating, cooking, ventilation and appliances, lighting etc.) and for dwelling energy rating it use some standard assumptions ...
Water audit is a useful tool to determine the water use efficiency in an irrigation project by accounting water losses. The clear-cut objectives of water audit applicable to irrigation systems include scope of distribution network, deliverables such as yield available and water efficiency, delivery locations/command areas and types of losses.
In the 2006 regulations, the u-value was replaced as the primary measure of energy efficiency by the Dwelling Carbon Dioxide Emission Rate (DER), [19] an estimate of carbon dioxide emissions per m 2 of floor area. This is calculated using the Government's Standard Assessment Procedure for Energy Rating of Dwellings (SAP 2005). [20]
Water efficiency is the practice of reducing water consumption by measuring the amount of water required for a particular purpose and is proportionate to the amount of essential water used. [ 1 ] [ 2 ] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use. [ 3 ]
Water Sensitive Urban Design with Green Infrastructure in the bottom right corner.. Water-sensitive urban design (WSUD) is a land planning and engineering design approach which integrates the urban water cycle, including stormwater, groundwater, and wastewater management and water supply, into urban design to minimise environmental degradation and improve aesthetic and recreational appeal.

The Home Energy Rating is an American estimated measurement of a home's energy efficiency based on normalized modified end-use loads (nMEULs). [1] In the United States, the Residential Energy Services Network (RESNET) is responsible for creation and maintenance of the RESNET Mortgage Industry National Home Energy Rating Standards (MINHERS), a proprietary system of standards, [2] which includes ...
