Evaluating energy consumption, indoor air quality, and student productivity

Air-conditioning: Energy Consumption and Environmental Quality

the impact of optimizing energy consumption on indoor air quality case study: educational building

introduction reducing and optimizing energy consumption and consequently environmental pollution reductions, besides improving building performance providing occupants comfort conditions, make the building's concept closer to the concept of green building and sustainability. once the decision to build green has been made, one of the first steps in the green design process is to establish f...

The effect of perceived indoor air quality on productivity loss

This theoretical study reports on the impact of perceived indoor air quality for productivity loss in air-conditioned office buildings. A new derivation of productivity calculation model based on pollution loads and contaminant removal effectiveness is applied and the effect of the improved ventilation efficiency on productivity is estimated. The findings show that the proportion dissatisfied i...

Energy Efficiency and Indoor Air Quality in Schools

Overview In the 1998-99 school year, U.S. K-12 public schools provided instruction to over 46 million students. An estimated 70% of all school buildings have indoor air quality (IAQ) problems, leading to an unhealthy environment. Because children breathe a greater volume of air relative to their body weight compared to adults, they may be more sensitive to indoor air pollution. Additionally, oc...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
