Effect of building shape, orientation, window to wall ratios and zones on energy efficiency and thermal comfort of naturally ventilated houses in tropical climate
TL;DR: In this paper, the effect of building shape, zones, orientation and window to wall ratio (WWR) on the lighting energy requirement and the thermal comfort in the naturally ventilated houses in tropical climate was examined.
The impact of urban green infrastructure as a sustainable approach towards tropical micro-climatic changes and human thermal comfort
TL;DR: In this paper, the performance of vertical green walls in tropical conditions is evaluated by quantifying thermal performance, relative humidity (RH) and CO2 concentration for basic three types of green infrastructures; such as (T1) living walls, (T2) indirect green facades and (T3) direct green facade located in Colombo metropolitan in Sri Lanka.
