Energy consumption prediction of office buildings based on echo …
Abstract. In this paper, energy consumption of an office building is predicted based on echo state networks (ESNs). Energy consumption of the office building is divided into consumptions from sockets, lights and air-conditioners, which are measured in each room of the office building by three ammeters installed inside, respectively.

Modulating d-orbital occupancy via a coupled interfacial-local electric field …
As evidenced in Fig. 5 e, WO 3-C 3 N 4 presents a negative free energy (−0.14 eV) of N 2 adsorption and a lower energy barrier (0.891 eV) for the rate-limiting step (RDS), transitioning from *N-N to *NNH, when compared with …
Do occupancy-responsive learning thermostats save energy? A field …
This article is the first field evaluation of energy savings from occupancy-responsive thermostats within academic literature. We illustrate that standard practice building energy simulations can easily overestimate the energy savings for these thermostats, and that most previous field evaluations have made simplifying …
Improving the accuracy of energy baseline models for commercial buildings with occupancy data …
Therefore, if the occupancy rate is changed after energy retrofit, the baseline of energy use should be adjusted. Although a number of previous studies emphasized the importance of occupancy factor in predicting the baseline, few studies, if not none, used occupancy factor in baseline prediction models, probably due to the …
Energy consumption prediction in an office building by examining occupancy rates …
Occupancy rate refers to the level of usage and presence of individuals within a building or a specific space. This factor can have a significant impact on building energy consumption. When the occupancy rate in a building is high, naturally, energy consumption also increases. This correlation might …
Energy Storage Placements for Renewable Energy Fluctuations: A …
In this paper, we analyze the dynamic performance of the conventional-storage frequency regulation model and provide parameter and capacity setting rules for storage. Furthermore, we allocate the storage capacity to buses under different operation modes to
Ring type and π electron occupancy decides the Li-ion storage …
DOI: 10.1016/J.CARBON.2017.12.074 Corpus ID: 103104900 Ring type and π electron occupancy decides the Li-ion storage properties of Phagraphene: An example of sp2 hybridized carbon structure The progress of ecofriendly, clean, and sustainable energy ...
A review of energy storage types, applications and recent …
Energy storage is an enabling technology for various applications such as power peak shaving, renewable energy utilization, enhanced building energy systems, and advanced transportation. Energy storage systems can be categorized according to …
A systematic review and comprehensive analysis of building occupancy …
In the field of architectural, occupancy prediction is of great significance for building design, energy management, and indoor environmental control [27, 28]. In the field of automation, occupancy prediction data can be used for intelligent control and resource optimization in smart homes and smart offices [ 29, 30 ].
Quantifying Energy Savings from Optimal Selection of HVAC Temperature Setpoints and Setbacks across Diverse Occupancy Rates …
This paper aims to systematically compare the potential energy savings from fixed and optimal setpoints and setbacks across wide-ranging occupancy scenarios (four occupancy rates and 14 patterns). Energy simulations were conducted using the Department of Energy reference models for small, medium, and large office buildings to …
Improved operating strategy for air-conditioning systems based on the indoor occupancy rate …
There is enormous potential for energy saving if indoor occupancy rate (R) is introduced into the operation of central air-conditioning systems. Nikdel et al. calculated that 15–66 million GJ fossil fuel use, 0.9–3.7 million metric tons CO 2 emissions, and 168–658 million dollars in utility cost, would be saved in the U.S. if occupancy-based …
