Assessing the effectiveness of energy conservation measures (ECMs) prior to their actual implementation in buildings is critical. There is an increasing tendency to employ calibrated building energy models to quantify energy savings that could be achieved by ECMs to justify their implementation. However, there is empirical evidence that reveals noticeable discrepancies between simulated and mea...

Exceeded losses of nonstructural components from structural ones in most demolished buildings in previous earthquakes and its limitation on functionality of critical facilities and building serviceability after earthquakes should be got the point of view for accounting loss of building as a merit for building performance. This paper attempts to demonstrate the significant role of distribution p...

The ability to accurately determine localized building occupancy in real time enables several compelling applications, including intelligent control of building systems to minimize energy use and real-time building visualization. Having equipped an office workspace with a heterogeneous sensor array, our goal was to use the sensors in tandem to produce a real-time occupancy detector. We used Dec...

This paper presents an indoor occupancy estimator with which we can estimate the number of real-time indoor occupants based on the carbon dioxide (CO2) measurement. The estimator is actually a dynamic model of the occupancy level. To identify the dynamic model, we propose the Feature Scaled Extreme Learning Machine (FS-ELM) algorithm, which is a variation of the standard Extreme Learning Machin...

A wide range of events in buildings occur at sub-hourly frequencies. Notable examples include daylight-sensing control and manual adjustment of blinds and lights in response to sub-hourly illuminance variations. Such short-term changes can produce notable shifts in instantaneous solar and equipment loads, in turn affecting electrical energy demand. Although sub-hourly time discretization is cur...

The aesthetic and functional appeal of high-performance, open-plan office buildings presents special challenges. Extensive use glass at the building’s perimeter to improve visual comfort communication can negatively impact acoustic without proper design considerations. This study investigates utility a novel visualization approach documenting interactional acoustical on health well-being occupa...
