Assessing Housing Conditions in Indonesia and Its Association with Health and Well-being
Namira Sani and Hector Altamirano
Despite the growing evidence indicating the effect of housing conditions on health and well-being, there is no tool to assess and remediate the housing conditions in Indonesia related to health and well-being.
This study aims to assess housing conditions in Indonesia and their association with the health and well-being of the occupants by using questionnaires. Participants in this study were residents living in Greater Jakarta. The number of participants was 197 people with mostly live in non-apartment houses. It was found that most of the houses in Greater Jakarta were healthy in terms of housing density since overcrowding is not an issue where most of the participants at least have one bedroom for a maximum of two people.
However, having full-time ventilation is encouraged to have a better thermal environment in a tropical country like Indonesia. In conclusion, this study provides valuable insights for related stakeholders to improve housing conditions in Indonesia, considering the occupants’ health and well-being.
How does a storytelling intervention influence students’ behaviour during a school overheating event

A new story, “The Hottest Day in School”, was designed as a pre-heatwave intervention to enable children to have confidence to change their behaviour in school, such as drink more water during a heatwave. A control: intervention approach was taken for two schools, where 5 classes were read the intervention story following an advance high temperature warning being issued.
On the high temperature day, researchers visited classes and asked children to complete a sticker task to reflect on “my day” and “my better day”. 13 stickers were available to choose from including actions (such as remove clothing) and thermal comfort statements (such as too hot). Sticker diaries of children in the intervention classrooms show a higher frequency of stickers which reflect the heatwave messaging in the story than control classrooms. KS2 intervention classroom children were found to be twice as likely to select heatwave messaging stickers (ch-square test, p=0.03).
Adaptive Ventilation Strategies and Their Impact on Operative Temperatures in a Warm and Humid Climate
Neha Singhi, Divya Shree Devraj, Lucelia Rodrigues, Lorna Kiamba and Renata Tubelo
This study investigates this dynamic in the Kanchanjunga apartment, designed for natural ventilation. The research evaluates the effect of air pollution on indoor thermal temperatures and explores the potential benefits of adaptive ventilation strategies. Two models were analyzed: night ventilation and a temperature-dependent modulation profile. Both rely on opening windows during periods of better outdoor air quality and closing them during peak pollution times.
Results indicate that adaptive strategies reduce the duration when indoor temperatures exceed 30°C. Among the tested strategies, the temperature-dependent modulation profile was most effective across various spaces effective in maintaining comfort, as discomfort temperatures were only observed to exceed the comfort zone by 25% annually in some areas. These results emphasize the importance of not only designing for natural ventilation but also optimizing and adapting designs based on varying external conditions, such as air quality and temperature.
SUSTAINABILITY IN HEALTHCARE ARCHITECTURE: The Case of Maggie Centres and their Effect on the Health and Wellbeing of Occupants.
Kawthar Namakula, Lujain Hafiz, Lucelia Rodrigues, Lorna Kiamba and Renata Tubelo
The era of industrialisation and urbanisation has promoted the decline of healthcare architecture such that hospitals of today are no longer sustainable or advantageous to the health and wellbeing of users. This paper aims to analyse this by studying two Maggie Centres located in Oxford and Lanarkshire. These have been chosen because of their strong sustainability and humanity initiatives. Analysis of their light, views and thermal comfort aspects has been conducted in dynamic simulation software (IES-VE), with respect to the WELL Standard.
Results show that they perform poorly with regards to daylight and thermal performance thus indicating that their design does not offer a positive contribution to the health and wellbeing of occupants. However, their biophilic qualities are regarded useful. It is therefore recommended that design of hospitals and care centres should include both qualitative and quantitative assessment of sustainability objectives lest they risk danger to the health of their visitors.
Thermal Comfort and Childcare, Kerala, India
This research investigates what thermal comfort means to children living in institutionalized care in Kerala by evaluating their adaptive behavior. While there are research on thermal comfort and children, there are no available data on children from vulnerable backgrounds or living in care system. Field study methods like comfort surveys, environmental measurements and semi-structured interviews were adopted. One Boys Home and one Girls Home were selected and collected total 90 responses.
Some children despite mentioning the environment was hot/warm also related to it as slightly comfortable, this major finding establishes the wider tolerance range to the environment. Lack of thermal memory and no access to thermal controls resulted the children having higher thermal acceptability rate. There was disparity in responses between genders. Girls had strong preference and expectations from their environment while boys were more acceptable and tolerant of their environment even during the heat waves recorded during study.
Evaluating Indoor Air Quality in Buildings
Yaqin Tang, Wenzhuo Li and Valentina Marincioni
Indoor air quality plays a vital role in maintaining the health, comfort and well-being of building occupants. This report compares indoor PM2.5 and CO2 data, outdoor PM2.5 and NO2 data and weather station data
against existing guidelines to analyse the differences in air quality between rooms and the potential causes of these conditions, in addition to explaining comparisons between pollutants and the frequency distribution of pollutant concentrations and exploring the possible causes. After illustrating the main findings, the building is modeled using DesignBuilder and the recommended interventions are found, briefly exploring the potential impact of the recommended measures on other aspects such as energy consumption, noise, thermal comfort etc.
