Some HVAC systems save energy by creating stratified air temperature distributions in which the occupied lower regions are cooler and the upper regions warmer. Comfort standards prescribe a 3°C limit to vertical stratification, independent of where the mean temperature is relative to the comfort zone. This paper evaluates thermal comfort in stratified environments using a model developed to pre...

This article focuses on adopting effective and affordable bioclimatic building design strategies in Ouagadougou, the Sudano-Sahelian zone of Burkina Faso. A model representing a standard office relevant parameters were input EnergyPlus, scenarios analyzed to evaluate effect natural ventilation, window shading, dehumidification with night evaporative cooling ventilation thermal comfort energy co...

from building design point of view a basic aim of low energy architecture is to create a thermally comfortable internal environment for building occupants whilst consuming the least possible amount of energy. thus, thermal comfort study has an important impact on energy saving. achieving comfort conditions requires an understanding of the interaction between three groups of factors, namely phys...

In this study, academic staff residential buildings were studied as part of a university campus located in hot and humid climate zone Türkiye. Within the scope energy efficient architectural landscape design decisions built 1976 examined. The aim was to determine performance about 50 years ago quantify effect changing conditions on thermal comfort. aim, outdoor comfort level determined by creat...

This study evaluates the influence of environmental variables on users’ thermal comfort and air quality perception in humid subtropical climate Florianópolis, southern Brazil. A building with central air-conditioning system three mixed-mode buildings, which alternated between natural ventilation modes, were investigated. Statistical analyses performed considering data collected situ 2014 2016 –...

Since low-income and social housing are among the most vulnerable built environments to climate change, this article evaluates energy performance of in context enabling net-zero carbon South Africa (SA). It seeks investigate how improved conscious energy-efficient design contributes toward a change mitigation response SA. The analyses use indoor comfort, based on ASHRAE 55-2004 Standard, two ca...

the process of constructing buildings is a complex activity, which has a variety of impacts on our environment, society and economy. buildings provide shelter, encourage productivity, embody our culture and can create a great legacy for the future while at the same time establishing links with the past. but they also consume a huge share of our land, energy, water and material resources. regard...

A set of enhancements to the ASHRAE Handbook are presented to demonstrate the effectiveness ofmultimedia and advancedpresentation techniques, such as three-dimensional computer graphics, visualization, and animation techniques. These results can also serve as a model and guide for the broader use of these techniques in other ASHRAE publications. GENERAL INTRODUCTION TO PROJECT In this paper, we...

THE INTELLECTUAL INVENTION THAT SURPASSES ALL OTHERS AS THE MOST BENEFICIAL ADVANCE OF HUMAN HISTORY IS RARELY UNDERSTOOD OR APPRECIATED BY EDUCATED ADULTS. With dire consequences for such neglect, there has been no applause for this wondrous invention, no gratitude for its beneficence, no monuments to hail its priceless influence. Largely overlooked, ignored, or taken for granted, this unceleb...
