Consulting engineers who design school facilities are challenged with controlling space humidity while also providing continuous ventilation as required by ASHRAE Standard 62-1999, now part of most major building codes. What would appear to be a simple design process is complicated by various logistical and operational factors. Schools, by nature, have a high occupant density which results in l...

The concept of Design-Build-Operate Energy Information Modeling (DBO-EIM) is proposed. The DBO-EIM aims at creating a detailed and persistent energy model that can be used to reduce energy consumption and improveoccupant comfort throughout the life-cycle of a building. Within the framework, the model is builtto supportdecision makingin the design phase, validated and tuned during construction a...

Today, environmental pollution and global warming have become threats. The use of renewable energy sources is a rational approach to overcome this problem, ground source heat pumps also play an important role in approach. However, the refrigerants used these systems often potential values above specified norms. In study, using Engineering Equation Solver package program, performance values, eff...

This study describes and compares the results of two field surveys about thermal comfort inside air conditioned buildings in two different classrooms. Both field studies were conducted in classrooms at The University of South Florida, Tampa, USA during the summer of 2014 and the fall of 2015. The purpose of this study is to investigate the temperature perception of humans in closed areas based ...

The conventional design of air-conditioning plants using large-tonnage chillers calls for a condenser-water flow rate of 3 gallons-perminute-per-ton-of-refrigeration (GPM/TR). For years, this standard has been thought to offer a good balance between first cost and energy cost. Recently, this conventional design has been challenged by proponents of a 2 GPM/TR design. These proponents suggest tha...

The Talk Test (TT) is a simple technique for prescribing exercise training intensity, based on the ability to ‘speak comfortably’ after reciting a standard speech provoking stimulus. This study compares the length of the speech provoking stimulus on power output (PO) at standard TT speech comfort markers: last positive (LP), equivocal (EQ), negative (NEG), in relation to objective markers of ex...

The ATP-binding cassette (ABC) family of transporters, including ABCC3, is a large family of efflux pumps that plays a pivotal role in the elimination of xenobiotics from the body. ABCC3 has been reported to be induced during hepatic stress conditions and through the progression of some forms of cancer. Several lines of evidence have implicated the transcription factor nuclear factor (erythroid...

In an era of high-profile hacks, information leaks and cybercrime, cybersecurity is the focus of much corporate and state-funded research. Data visualization is regarded as an important tool in the detection and prediction of risk and vulnerability in cybersecurity, but discussion tends to remain at the level of the usability of visualization tools and how to reduce the cognitive load on the co...
