Research is needed to explore the limitations and potential for improvement of machine learning building energy prediction. With this aim, ASHRAE Great Energy Predictor III (GEPIII) Kaggle competition was launched in 2019. This effort largest meter its kind, with 4370 participants who submitted 39,403 predictions. The test dataset included two years hourly whole readings from 2380 meters 1448 b...

Vapor refrigerant injection cycle with a flash tank has proven to be effective in improving system performance significantly at extremely low and high ambient temperatures. However, the control strategy of operating the system is still unclear. There is no open publication on the comprehensive study of the vapor injection cycle control strategy to date. This paper presents the experimental inve...

This case study investigated office occupant thermal comfort in Lawrence Hall. More specifically, it focused on the winter heating season thermal comfort in these office spaces. In a building that is composed of approximately seven major additions and/or renovations spanning nearly a century, the variety of heating and ventilation systems varies greatly. The combination of qualitative and quant...

This paper demonstrates the possibility of achieving a higher Energy Efficiency Ratio (EER) for Room Air Conditioners (RACs) that complies with the Saudi energy efficiency standards and satisfies the energy conservation requirements for the Saudi Building Code (SBC). This study considers several design options for improving the performance and efficiency of the RAC in comparison with a baseline...

The blood-testis barrier (BTB) prevents the entry of many drugs into seminiferous tubules, which can be beneficial for therapy not intended for the testis but may decrease drug efficacy for medications requiring entry to the testis. Previous data have shown that some of the transporters in the multidrug resistance-associated protein (MRP) family (ABCC) are expressed in the testis. By determinin...

Radiography by computed tomography for dental and jaw use (dental CT) has recentry attracted attention as a new diagnostic imaging technique in dentistry. The 3DX Multi-Image Micro CT® (3DX, Morita) is the first exclusively registered dental CT in Japan. A high-definition 3-dimensional image of a cylindrical imaging area, 40 mm in diameter and 30 mm in height, can be taken by using a small-type...

Recent evidence available in the literature has highlighted that high-energy consumption rate associated with air conditioning leads to undesired “overcooling” condition arid-climate regions. To this end, study quantified effects of increasing cooling setpoint temperature on reducing energy and CO2 emissions mitigate overcooling. DesignBuilder software was used simulate performance a generic bu...
