The environmental measurement of buildings has historically relied on analogue or digital data logging equipment located reasonably close to hard wired temperature and humidity sensors. Occasionally, the data logging devices included WAN based systems to upload data to an off-site server. Invariably, these methods allowed for data to be analysed months after collection. The advent of increased wifi, data and radio network typologies, combined with more flexible low current sensor technologies has allowed for the redesign of building environmental measurement and management systems. Recent research in Australia has utilized cloud based servers as points of data storage for temperature, relative humidity and current transducer sensors connected to data network transmission devices. Initially developed for the purpose of assessing causes of condensation and mould within roof spaces, subfloor zones, and interior zones of new homes, this methodology is now being explored for much greater data gathering functions and data driven building management systems. Australia, like many nations, has many older homes with low quality external envelopes and newer homes with questionable internal environmental conditions. With an increasingly aged population, who choose to age at home, live data is required to inform the quality of internal environments to enable real-time action by care providers or the automated operation of home based heating, cooling and ventilation systems. The use of temperature, relative humidity, infra-red and microwave sensors, combined with a new generation of wireless and radio frequency based data transmission system can provide the data needed to better provide healthy internal environments.
