The well-known experiment of the rapid expansion and cooling of the air contained in a bottle is performed with a rapidly responsive, yet very cheap thermometer. The adiabatic, low temperature limit is approached quite closely and measured with our apparatus. A straightforward theoretical model for this process is also presented and discussed.…

The project models the conductive heat loss through the ceiling of a home. Students are led through a sequence of tasks from measuring the area and insulation status of a home to developing several functions leading to a net savings function where the depth of insulation is the input. At this point students use calculus or a graphing utility to…

Facility managers everywhere are tasked with improving energy efficiency to control costs. Those strides cannot be achieved at the expense of system performance and reliability, or the comfort of the people within those properties. There are few places where this is truer than in schools and universities. K-12 schools and university lecture spaces…

Perhaps more than many other industries, today's universities and colleges are beset by dramatically rising costs on every front. One of the areas where overhead can be contained or reduced is in the operation of the chilled water systems that support air conditioning throughout college campuses, specifically the cooling towers. Like many…

Self-declared energy and carbon reduction goals on the part of progressive colleges and universities have driven ground source geothermal space heating and cooling systems into rapid evolution, as part of long-term climate action planning efforts. The period of single-building or single-well solutions is quickly being eclipsed by highly engineered…

The problem of maintaining hygrothermal comfort in a house is addressed using the chemical engineer's toolbox. A simple dynamic modelling proved to give a good description of the humidification of the house in winter, using a domestic humidifier. Parameters of the model were identified from a simple experiment. Surprising results, especially…

This paper explores the effectiveness of using "structured examples in concert with prompting reflective questions" to address misconceptions held by mechanical engineering students about thermodynamic principles by employing pre-test and post-test design, a structured questionnaire, lecture room observation, and participants'…

Like most schools, College of William and Mary is not shy about touting its amenities. The Webpage that advertises the college's housing and dining options begins with, "Wireless and Starbucks? Thomas Jefferson never had it this good." Advertising of this sort is a double-edged public-relations sword. Colleges and universities clearly want to…

Displacement ventilation (DV) units use the natural buoyancy of warm air to improve ventilation and comfort. Although relatively new to the United States, DV has been used in Scandinavian countries since the 1970s. Two types of DV can be used in a classroom: (1) Conventional displacement ventilation (CDV) units which are situated on an interior…

From around the corner to around the nation, schools and universities are looking to reduce their energy bills. Some are concerned about fuel costs and the impact on their operating budgets; others are motivated by the desire to reduce their carbon footprints and their impacts on the environment. Professionally installed window film can play a key…

"Proceedings of International Conference on Research in Education and Science" includes full papers presented at the International Conference on Research in Education and Science (ICRES) which took place on March 24-27, 2022 in Antalya, Turkey. The aim of the conference is to offer opportunities to share ideas, to discuss theoretical and…

Colleges and universities have been among the leaders nationwide in adopting green initiatives, partly due to their demographics, but also because they are facing their own budget pressures. Virtualization has become the poster child of many schools' efforts, because it provides significant bang for the buck. However, more and more higher…

Nearly every institution is faced with the situation of having to reduce the cost of a construction project from time to time through a process generally referred to as "value engineering." Just the mention of those words, however, gives rise to all types of connotations, thoughts, and memories (usually negative) for those in the…

When schools and universities look at saving energy in their facilities, they are likely to review the efficiency of their heating and cooling systems, or the quality of their building envelopes. When facility managers focus attention on school bathrooms, they are more likely to consider issues such as cleanliness and safety as more critical than…

Education facilities managers are faced with a daunting set of challenges: They must find new ways to reduce energy consumption and carry out greener energy policies. HVAC typically accounts for more than 30% of a building's electricity costs, so there is a clear incentive to eliminate unnecessary heating and cooling of unoccupied rooms. With more…
