TL;DR: In this article, a data mining-based prediction model is constructed to mimic building thermal behaviors, and the experimental results make it evident that prediction accuracy is improved when considering diverse occupancy and its correlation with energy use.

09 Jul 2014TL;DR: In this paper, the authors used wavelets to identify features that correspond to heat loads generated by occupant presence and/or equipment operation from this information, the occupancy state of individual rooms can be estimated and then can be used to generate a usage profile for the building.
Abstract: Systems and methods are disclosed for the generation of more accurate usage profiles for use in the modeling of existing buildings Building sensor data associated with individual rooms in a building can be decomposed using wavelets to identify features that correspond to heat loads generated by occupant presence and/or equipment operation From this information, the occupancy state of individual rooms can be estimated The estimated occupancy state for the individual rooms in the building then can be used to generate a usage profile for the building The usage profile can be used to estimate current and/or future energy usage or costs or to control equipment in the building at a current and/or future time

TL;DR: An improved extrapolative time series forecasting technique to compute future hotel occupancy rates is proposed and empirical results indicate that the new technique is promising with reasonably good forecasting results.
Abstract: SUMMARY The existing time series forecasting models either capture the informationof the last few data in the data series or the entire data series is used for projecting future values. In other words, the time series forecasting models are unable to take advantage of the last trend in the data series, which always have a direct influence on the estimated values. This paper proposes an improved extrapolative time series forecasting technique to compute future hotel occupancy rates. The performance of this new technique was tested with officially published room occupancy rates in Hong Kong. Forecasted room occupancy rates were compared with actual room occupancy rates in several accuracy performance dimensions. Empirical results indicate that the new technique is promising with reasonably good forecasting results.

TL;DR: It is concluded that camera trapping provided useful and cost-effective insight into the factors limiting rock-rat distribution, and predicted that it will become a standard tool for sampling rare small mammals in difficult-to-access environments.
