Implications of resource-efficient technology on peak water demand and water-related energy demand

摘要: This paper uses a detailed water end use data registry generated from the South East Queensland Residential End Use Study (SEQREUS) to examine (a) peak hourly and daily demand, (b) water-related energy demand. The impact of water-efficient fixtures appliances, as required by current building codes in Queensland, is also explored. four demand days selected had increasing day factors 1.3, 1.5, 1.6 1.7. range these values slightly lower than those used Department Environment Resource Management (DERM) guidelines where 1.5 2.3, suggesting that frequency volume peaking may be are currently being for network distribution design; due likely high penetration technology growing conservation awareness consumers. type knowledge can facilitate optimisation infrastructure design sizing inform subsequent deferral such assets.
