Abstract

This study investigates the comfort levels of co-working spaces within modern cafés in Manado City, focusing on three primary environmental factors: thermal, lighting, and acoustic conditions. The emergence of the Work from Café (WFC) trend among the younger workforce underscores the need for adaptive spatial environments that support productivity. Utilizing a mixed-method approach, both quantitative measurements and qualitative perceptions were collected from 34 café visitors actively working during weekdays. Tools such as the Delta Ohm HDTC 32.3, Lux Meter, and Sound Level Meter were employed to assess temperature, light, and noise levels, respectively. The results reveal that thermal comfort is the most influential factor, with air temperature showing a significant positive correlation with perceived comfort, whereas humidity and wind speed had minimal impact. Conversely, lighting intensity and glare were found to have weak correlations with visual comfort, and acoustic measurements indicated a discrepancy between objective noise levels and subjective perceptions, suggesting user adaptation. These findings highlight the divergence between physical measurements and individual experiences in informal workspaces. The study concludes that enhancing thermal conditions, managing acoustics, and re-evaluating lighting design are essential strategies for café operators aiming to optimize their spaces for co-working users. The research contributes to a deeper understanding of environmental comfort in semi-public work settings and offers practical insights for architectural and interior design improvements in modern cafés.

Abstract

The objective of this study is to determine the role of landscape materials in microclimate changes within a tropical humid environment, specifically in coastal areas. Landscape materials possess thermophysical properties that can influence microclimate changes. This study focuses on three microclimate variables: surface temperature, air temperature and solar radiation. The landscape materials examined include bricks, dry` soil, paving stones, trees, and a garden pond. A quantitative descriptive analysis method was employed. Thermophysical properties of local materials, such as red bricks and paving blocks, were measured using a calorimeter, infrared thermometer, and thermocouples. Microclimate measurements were conducted in the open space of a commercial zone at coastal area of Manado City, Indonesia. The measurement include solar radiation, air temperature, and surface temperature of various materials. The HEAT2 computer program was used to assist in analyzing changes in surface temperature due to the presence of different landscape materials. The results revealed that at midday, trees could reduce solar radiation by up to 80% under their shade. Conversely, materials like bricks, paving stones, and hard soil, when exposed to direct sunlight, could cause surface temperatures to reach up to 50°C. The surface temperature of the garden pond water could reach 50°C, but at a depth of 50 cm, the temperature dropped to 25°C.
