Why are modern homes feeling hotter than older wooden houses?

Question

Accepted Answer

Modern Homes Are Hotter Due to Reduced Natural Ventilation and Urban Development

Modern homes, particularly apartments and condominiums, are perceived as hotter than older wooden houses primarily due to a significant reduction in natural ventilation and the exacerbating effects of urban development. Older dwellings, such as traditional wooden houses and shophouses, were designed with features that facilitated natural cooling and insulation, contrasting sharply with the construction and environmental context of contemporary residences. The shift from materials like timber, which has lower heat absorption properties, to brick, coupled with increased urban density and a decrease in heat-absorbing greenery, contributes to the heightened temperatures experienced in newer homes.
Older Homes Utilised Natural Ventilation and Materials for Insulation

Traditional housing designs incorporated elements that enhanced natural airflow and thermal comfort. For instance, older wooden houses, often with attap roofing, provided superior natural ventilation and insulation against external heat. Timber itself is a material that does not absorb heat as readily as brick, contributing to a cooler interior environment. Shophouses, another example of older architecture, were strategically designed with courtyards and air wells to promote ventilation, allowing hot air to circulate and escape effectively.
Urbanisation and Development Have Increased Ambient Temperatures

The surrounding environment plays a crucial role in perceived temperature. Older homes were typically situated in areas with more trees, which helped absorb heat and mitigate its intensity. In contrast, modern urban development has led to increased construction density, with buildings often erected in close proximity. This clustering, combined with a reduction in natural green spaces, creates an urban heat island effect, where built-up areas retain and radiate more heat, leading to higher ambient temperatures that impact surrounding residences.
Modern Homes Lack Traditional Cooling Features

Contemporary housing, especially high-rise apartments and condominiums, often lacks the natural ventilation systems found in older homes. The architectural designs of many modern apartments do not integrate features like air wells or courtyards that facilitate passive cooling. Consequently, residents often rely on artificial cooling methods such as air conditioning and fans, which, by circulating air, can inadvertently contribute to the feeling of increased heat within the living space.
High-Rise Living Exacerbates Heat Exposure

Living in high-rise apartments can lead to intensified heat exposure due to their elevated position and surrounding built environment. Units on higher floors may experience direct and prolonged sun exposure, particularly during certain times of the day. The proximity to other buildings can also trap heat, creating a microclimate that feels significantly hotter. This phenomenon is further amplified when artificial cooling systems are insufficient or when residents are unable to afford air conditioning, making the heat more unbearable.
