In order to examine the associations between different indoor environmental quality (IEQ) indicators and students' performance, absenteeism and health data were collected, and sampling and monitoring were conducted in a 70 school district in the Southwestern United States during two academic years. These included measurements of temperature (T), relative humidity (RH), carbon dioxide (CO2), and settled dust. A standardized cleaning protocol was employed for surface sampling and cleaning...

Using a multilevel approach, we estimated the effects of classroom ventilation rate and temperature on academic achievement. The analysis is based on measurement data from a 70 elementary school district (140 fifth grade classrooms) from Southwestern United States, and student level data (N = 3109) on socioeconomic variables and standardized test scores. There was a statistically significant association between ventilation rates and mathematics scores, and it was stronger when the six...

Global efforts to prepare young developing minds for solving current and future challenges of climate change have advocated interdisciplinary, issues-based instructional approaches in order to transform traditional models of science education as delivering conceptual facts (UNESCO, 2014). This study is an exploration of the online interactions in an international social network of high school students residing in Norway, China, New Zealand and the United States (N=141). Students participated...

To apply real-time predictive control using automated devices for minimizing the risk of surface condensation in a residential space, the authors first developed a nodal network model that simulates the flow of moist air and the thermal behavior of a target area with the given boundary conditions of a space. The lumped model was enhanced using a parameter estimation technique based on the measured temperature, humidity, and schedule data. However, the humidity model prediction performance...

Low cost temperature sensors are increasingly used by ecologists to assess climatic variation and change on ecologically relevant scales. Although cost-effective, if not deployed with proper solar radiation shielding, the observations recorded from these sensors will be biased and inaccurate. Manufactured radiation shields are effective at minimizing this bias, but are expensive compared to the cost of these sensors. Here, we provide a detailed methodology for constructing a compact version...

The study reported here focuses on integrating climate change issues in School curriculum in The Gambia. The objectives are to determine the extent to which climate-related themes presently feature in the Upper Basic (lower secondary) schools of The Gambia; propose an integration plan for enhanced climate themes in the school curriculum; and identify suitable teaching methods for conveying climate change information to students. A curriculum audit of two subject areas in the Upper Basic...

In this article, a simple approach to modeling heat transfer between the outside environment to a location inside a building is used to precisely predict indoor temperatures for a large range of historical dates. The data collection, statistical modeling and prediction of inside temperature based on available weather data obtained outside the building of interest are presented. An initial simple linear regression model estimates the heat transfer mechanism between outside and inside which is...
