due to climate changes in recent years, in order to attain comfort and convenience, demands for heating, ventilating, and air conditioning (hvac) systems have been increased around the world, which has led to increases in emissions and power. desiccant cooling systems (dcss) are designed and built to reduce moisture and power consumption, create comfortable conditions for people in a building, ...

Abstract Recent studies underline that simple and non-invasive retrofit solutions can recover natural ventilation potential in existing buildings under temperate climate. Nonetheless, the efficiency of these dense urban contexts hot humid climate remains unclear. This paper aims to evaluate thermal comfort gains caused by when retrofitting an office building downtown Rio de Janeiro. Computation...

Increasing water use and droughts, along with climate variability and land use change, have seriously altered vegetation growth patterns and ecosystem response in several regions alongside the Andes Mountains. Thirty years of the new generation biweekly normalized difference vegetation index (NDVI3g) time series data show significant land cover specific trends and variability in annual producti...

introduction in general, loess sediments are one of the most widespread forms of aeolian sediments. during the past few decades, loess stratigraphy studies played key role in the investigation about global climate changes. these sediments are usually yellowish in color and silt makes 70 to 90 percent of its volume. in iran, loesses outcrop are often in northeast part of south caspian sea. the p...

Because of the differences between indoor and outdoor thermal condition, preparing some outdoor thermal indices is a way to understand and categorize the outdoor thermal sensation. The aim of these indices is not to provide thermal comfort - as it is the aim of indoor indices. Instead, they are provided to analyze outdoor thermal sensation to help architects, landscape architects and urban desi...
