Impact of Humidity on Residential Buildings in Dhaka City: A Case Study in Wari

Ahmed, Farhana / Rashid, Rumana

The significance of relative humidity in Indoor Air Quality (IAQ) cannot be overstated, as an excess of moisture poses the risk of mold growth, threatening both the structural integrity of buildings and human health. This study undertakes the evaluation of humidity levels and mold condensation in inadequately ventilated residential buildings, concentrating on Dhaka city. Its primary objective is to scrutinize how these factors impact the structural integrity and maintenance of residential buildings, adopting a comprehensive quantitative research approach. The study incorporates a synthesis of experimental field surveys, analysis, and simulation methods, drawing insights from reputable publications that quantify the impact of indoor air humidity and performance. In order to concurrently optimize these criteria, the study employs multi-objective Optimization techniques, adjusting parameters like relative humidity (RH) and temperature based on indoor environmental conditions (such as open and closed windows, air conditioner usage, heating, and fan operation). The specific aim of the research is to evaluate how RH and mold condensation influence the structural integrity and maintenance of residential buildings in Dhaka. The outcomes of the study provide a basis for recommendations in designing residential buildings in Dhaka, emphasizing the need for effective ventilation systems, moisture control measures, and durable building materials. Additionally, the research underscores the necessity for clear guidelines and policies to tackle indoor air quality issues in the city. The findings contribute valuable insights for architects and designers in creating healthier and more enduring living spaces, aligning with the broader objective of enhancing indoor air quality.
