TL;DR: In this article, the indoor air temperature reduction of 5 courtyard houses design of the contemporary boarding house in Surabaya, East Java, Indonesia, was investigated using field measurement, where each sensor was shaded with a paper cups wrapped with the aluminum foil to prevent the effect of direct thermal radiation.
Abstract: Courtyard in building contributes to indoor thermal environment. Courtyard element is commonly applied as passive cooling strategy in the design of boarding house in Indonesia. Courtyard has a potential aspect of being micro climate-modifier to reduce indoor air temperature during the day. This paper discusses the effects of courtyards on indoor thermal environment in Indonesian contemporary boarding houses using field measurement. This paper focuses on the indoor air temperature reduction of 5 courtyard houses design of the contemporary boarding house in Surabaya, East Java, Indonesia. The field experiment method was used for two physical environmental variables: the air temperature and relative humidity. Each sensor was shaded with a paper cups wrapped with the aluminum foil to prevent the effect of direct thermal radiation. Measurement was taken for approximately 23 days continuously in each building. The results of the measurement exposed that the form and enclosure element is pivotal in its thermal environment design consideration for tropical climate. Meanwhile, utilizing ventilation blocks as the primary enclosure also help reduce air temperature in hot-humid climates. The results showed that the indoor air temperatures in the courtyard and surrounding room were approximately 0.3-1.7°C lower than the outdoor air temperature during daytime. During night-time, indoor air temperatures inside swing to 0.8-1.9°C higher than the outdoor. The results of the thermal environment evaluation revealed that indoor air temperatures can be categorized as a neutral temperature of the measurement period. Therefore, the application of courtyards in contemporary boarding houses have proven as possible means of achieving sufficient cooling effects through full-day ventilation strategy, and showed improved performance when combined with ventilated blocks.

TL;DR: In this paper, the authors explored strategies that can be done to improve natural lighting in the cultural heritage buildings with a deep floor plan, by minimizing the incoming glare through the consideration of the vertical angle of the sun's shadow, as well as the reflection of light.
Abstract: Tropical climate areas have an advantage in terms of utilizing natural lighting for buildings. On the other hand, deep plan buildings have limitations in natural light penetrations through the sides of the building, while making the natural light enters from the roof risks of blending in with the heat and glare. Cultural heritage buildings are an inheritance that must be preserved and protected. Nowadays, some of them switch functions to be managed as public functions. Cultural heritage buildings with deep floor plans have double problems, specifically their limitations in natural light penetrations from the sides of the building, and also how to maintain the visual appearance of the building as much as possible when renovations are being carried out. This paper aims to explore strategies that can be done to improve natural lighting in the cultural heritage buildings with a deep floor plan. A case of study of cultural heritage buildings was also used in this research to provide a description of specific natural lighting techniques that can be applied. Field measurement methods and digital simulations are used to determine the existing natural lighting conditions of the study object and provide a visualization of design recommendations. The results show that vertical lighting can be used in cultural heritage buildings without changing the building façade. This strategy is carried out by minimizing the incoming glare through the consideration of the vertical angle of the sun's shadow, as well as the reflection of light to maximize the light distributions in the building.

TL;DR: In this paper, the authors investigated the effectiveness of natural ventilation performance in terraced housing with an air-well system and found that the air temperature of the air well ranged from 27.48 °C to 30.92 °C, with a mean relative humidity of 72.67% to 79.25%.
Abstract: The provision requirement of 10% openings of the total floor area stated in the Uniform Building By-Law 1984 Malaysia is essential for natural lighting and ventilation purposes. However, focusing on natural ventilation, the effectiveness of thermal performance in landed residential buildings has never been empirically measured and proven, as most of the research emphasized simulation modeling lacking sufficient empirical validation. Therefore, this paper drawing on field measurement investigates natural ventilation performance in terraced housing with an air-well system. The key concern as to what extent the current air-well system serving as a ventilator is effective to provide better thermal performance is to be addressed. By adopting an existing single-story air-welled terrace house, indoor environmental conditions and thermal performance were monitored and measured using HOBO U12 air temperature and humidity, the HOBO U12 anemometer, and the Delta Ohm HD32.3 Wet Bulb Globe Temperature meter for a six-month duration. The results show that the air temperature of the air well ranged from 27.48 °C to 30.92 °C, with a mean relative humidity of 72.67% to 79.25%. The mean air temperature for a test room (single-sided ventilation room) ranged from 28.04 °C to 30.92 °C, with a relative humidity of 70.16% to 76.00%. These empirical findings are of importance, offering novel policy insights and suggestions. Since the minimum provision of 10% openings has been revealed to be less effective to provide desirable thermal performance and comfort, mandatory compliance with and the necessity of the bylaw requirement should be revisited.
