This study develops an "indirect" practical data mining approach using office appliance power consumption data to learn the occupant "passive" behavior.
According to this estimation, which was confirmed by the regional electrical power distribution office, the cooling systems power consumption in this region accounted for more than 60% of the total power consumption during the peak load period of the year.
The contribution of this study is to design an EWA architecture that visually presents real-time anomalous power consumption in an office space based on data that are obtained from various instruments (smart meters and sensors) to office occupants.
This amounts to roughly 2% of the office complex's monthly power consumption.
The cooling load contributes 45 60% of total power consumption in commercial and office buildings, especially at tropics.
Reducing electrical use by that same 25percentt in each home, office and plant would cut regional power consumption by a whopping 133 million kilowatt hours.
An example for contextual anomalies can be found in a use-case such as power consumption likely has context-based, time-related relationships: it makes sense to posit that the power consumption of an office building is much higher during midday, during a work day, compared to at night, during a weekend.
In a trial in 2012, it asked all employees to work from home on the same day, leaving only 125 mission-critical employees in the building: employees saved 2,000 hours and £9,000 in commuting time and costs, while the office electricity consumption decreased by 12% and water use by 53%.
By the time Carter left office, the consumption of foreign oil had fallen by nearly two million barrels a day, to seven million barrels.
So far Sydney has committed to switching its streetlamps to energy saving LED; in Shenyang, China 38,000 hectares of land will be reforested; Chinese internet company Baidu has pledged to reduce office resource consumption by 30 per cent; and Credit Suisse AG has committed to continue its carbon neutral status and to help Brazilian rainforest preservation.
