The design of a building can provide the highest thermal comfort in the interior without any mechanical equipment and save energy to a large extent. The roof of a building is an important part for thermal loss. This research studies the thermal performance of 14 conventional roof structures in Tehran city by using designbuilder 4.5. It is found that the polystyrene block performs best compared ...

There have been few longitudinal studies on sick building syndrome (SBS), which include headache, fatigue, and runny nose. We considered effect of sick building syndrome with illnesses like headache, fatigue and runny nose. Thus, we designed a questionnaire and asked from male of dormitory residence. Questions of the questionnaire were more about known symptoms of buildings (headache, fatigue, ...

Electrophysiology is a valuable skill for the neuroscientist, but the learning curve for students can be steep. Here we describe a very simple electromyography (EMG) amplifier that can be built from scratch by students with no electronics experience in about 30 minutes, making it ideal for incorporating into a laboratory activity. With few parts and no adjustments except the gain, students can ...

This paper purports to provide answers to the following questions with regard to multi-crane building construction sites: (1) Do such construction sites differ from smaller sites only in magnitude, or are there unique characteristics that stem from the size of the site and the multitude of cranes? (2) Is equipment planning for such projects similar to that of projects serviced by a small number...

Smart building, which delivers useful services to residents at the lowest cost and maximum comfort, has gained increasing attention. HVAC equipment is a particularly expensive and energy consuming of building operation. A variety of emerging information technologies has been adopted. As a result, the concept of “demanddriven HVAC control” is a hot research topic. In this work, we investigated t...

In building energy simulation, indoor thermal comfort condition, energy use and equipment size are typically calculated based on the assumption that the clothing insulation is equal to a constant value of 0.5 clo during the cooling season and 1.0 clo during the heating season. The assumption is not reflected in practice and thus it may lead to errors. In reality, occupants frequently adjust the...
