Abstract

As one of the major urban growth centers in Indonesia, the city of Medan faces significant environmental challenges, including rising temperatures, declining air quality, and limited green open spaces in residential areas. This study examines the influence of landscape vegetation on thermal comfort in Royal Sumatera Housing as part of efforts to realize energy-efficient buildings. The research uses a descriptive qualitative method through observation and the measurement of temperature, humidity, and wind speed within the housing area. The analysis reveals that vegetation such as trees, shrubs, herbs, and bushes positively contributes to reducing temperature and improving thermal comfort, although humidity levels in some areas still exceed ideal standards. Cooler and more consistent wind speeds are also observed in areas with dense vegetation. These findings emphasize the importance of strategic landscape planning in creating thermally comfortable and energy-efficient environments in tropical residential areas.

Abstract

This study aims to analyze the influence of Green Open Space (GOS) and artificial air conditioning on air quality in the J. City Johor residential area, Medan. The research was conducted through observational methods by measuring temperature, humidity, and wind speed over seven consecutive days in three different zones: GOS, indoor areas, and outdoor areas. The results show that although indoor temperatures generally fall within the standard thermal comfort range (24–27 °C), humidity levels often exceed the recommended standard (>60%), particularly during midday and afternoon hours. This study highlights the importance of optimal GOS planning and adequate ventilation systems to ensure healthy and comfortable air quality in tropical residential environments.

Abstract

A healthy house is one that can fulfill the need for a healthy and comfortable living environment. This study aims to evaluate renovated houses in the Citraland Gama City residential area in Medan. The method used in this research is a descriptive qualitative approach, by evaluating the post-renovation condition of the houses based on three aspects of healthy housing comfort: lighting, temperature & humidity, and sound. The results of the study show that the renovated houses in Citraland Gama City meet the technical requirements of a healthy home, including adequate lighting, sound control, and thermal comfort. The conclusion of the study indicates that two variables (lighting and sound control) fall into the category of highly suitable for a healthy home, while one variable (thermal comfort) is categorized as suitably meeting the requirements of a healthy home.

Abstract

ABSTRACT Thermal comfort is a key indicator of residential environmental quality, particularly in tropical regions characterized by high temperatures and fluctuating humidity. This study aims to analyze the influence of green open space (RTH) on thermal comfort in the TASBI 1 Housing Complex in Medan. A quantitative descriptive approach was employed over five consecutive days, involving measurements of air temperature, relative humidity, and wind speed in two zones with differing levels of vegetation density. The results show that the presence of RTH significantly reduces the average daytime temperature by 5.3°C and increases relative humidity in the afternoon by 7.2%. Zones with dense vegetation exhibit cooler and more humid microclimates compared to areas with minimal RTH. Additionally, residents in high-RTH zones reported lower usage of air conditioning, indicating the role of vegetation in promoting energy efficiency. This research highlights the importance of integrating green elements into residential planning to create more comfortable, energy-efficient, and sustainable living environments.

Abstract

This research aims to examine the Vihāra Sukjai Sailendra building based on energy-saving architectural principles using temperature, humidity, and wind speed as benchmarks. The method used in this research is a qualitative method with a case study approach through observation.. The results of this research show that the Vihāra Sukjai Sailendra building is not an energy-efficient building when measured in terms of temperature. However, if measured in terms of humidity and wind speed, the Vihāra Sukjai Sailendra building is an energy-efficient building because it utilizes natural ventilation through multiple wall openings that create cross-ventilation, allowing the indoor air conditions to remain comfortable without the need for artificial cooling systems that require electrical energy to operate.
