Article
Full-text available
Traditional Indonesian architecture and Dutch colonial architecture in Indonesia often have an attic as an intermediate space with openings for ventilation and natural lighting. Most of the houses in residential areas in Manado have corrugated zinc roofs and no longer use attic ventilation. This article aims to examine the benefits of attic ventila...

Full-text available
There are 92% of house buildings in North Sulawesi Province in Indonesia uses zinc as the roofing material. The use of solar panels as an alternative energy source can also be used as an outermost layer of roof covering as heat retention; the largest and longest part exposed to direct sunlight. The problem facing house buildings in humid tropical c...

The dwelling house of Kampung Jawa Tondano community is originally a wooden house with Minahasa Traditional Architecture which is very distinctive and unique both its form and its construction. Kampung Jawa Tondano is a residential area located in the highlands of Minahasa, Indonesia. This settlement began in 1832 by a group of men who were all mal...
Article
Kenyamanan panas merupakan salah satu faktor penentu untuk meningkatkan produktivitas kerja. Penelitian ini dilakukan dengan mengukur kondisi fisik seperti suhu udara, kelembaban udara dan kecepatan aliran udara dalam ruang administrasi akademik Fakultas Teknik Universitas Sam Ratulangi Manado dan dengan menyebarkan kuesioner kepada karyawan dalam...
Book
Full-text available
Increasing demands for energy saving and a higher degree of comfort in rooms compels architects to use more sophisticated analysis methods. This book will describe the cases for analysis of natural ventilation performance by making use of Computational Fluid Dynamics (CFD) codes and Artificial Neural Networks. Firstly, this study will present the...
Conference Paper
This subject points to assess the benefits of the evaporative-cooling roof, particularly for buildings with corrugated zinc roofs. In Manado, many buildings have roofed with corrugated zinc sheets; because this material is truly practical, easy and economical application. In general, to achieve thermal comfort in buildings in a humid tropical clima...

Para insinyur, arsitek dan desainer dewasa ini diperhadapkan dengan masalah penghematan energi, terutama dalam merancang bangunan untuk hunian, kantor, komersial dan rekreasi. Hal tersebut dipicu oleh semakin mahalnya harga energi dari fosil dan semakin terbatas dan berkurang sumbernya. Di sisi lain tuntutan untuk mendesain ruang yang semakin nyama...
Conference Paper
Full-text available
The study aims to assess the cooling performance of the automatic water spraying on the roof surface to decrease the indoor air temperature in a humid tropical climate. The spraying water onto the ceiling can be considered as an evaporative cooling strategy. Firstly, the approach has been tested in a cell test constructed with plywood for the walls...
Conference Paper
The engineers and architects today confront the question of how to build energy-efficient buildings. The price of fossil fuels more expensive and limited source is the cause of this issue. The study aims to determine the usage of an indirect evaporative cooling strategy to cool the building for thermal comfort in a tropical humid climate. Comfort v...
Conference Paper
This study aims to develop a design concept that is responsive to climate, especially on buildings in a humid tropical climate. Hot and humid climatic condition is one crucial matter in achieving thermal comfort in buildings. Control of direct solar heat, which can cause excessive heating in the room is the central theme of the scope of this study....
Conference Paper
Keywords: Thermal comfort, Gender, Passive and low energy, Classroom building SUMMARY The classroom is an important facility in the learning process, therefore, a comfortable classroom is meant to better the performance of the educational activity and learning the process. Indonesia lies in humid tropical climates which have major problems of therm...

Full-text available
This article describes the results of a 2D numerical simulation by Computational Fluid Dynamics (CFD) of airflow distribution over all of building's storeys. Obstruction of a tall building with certain distances from the windward or the leeward side of a building storey was simulated in order to investigate its effects on air motion distribution. T...

Full-text available
Windows are of primary concern as vehicles for getting air into and out of buildings, and they must be chosen carefully for their air-controlling characteristics. In present study, we modelled two types of window: horizontal centre-pivot and top edge-hung types with 30, 45 and 60 degrees of shutter's inclinations, kept the same for inlet and outlet...

We have applied the lattice gas method with using Pascal program language. Some 2-D building models have been implemented in the simulation. The results showed that this method could be used and reliable for studying behavior of airflow pattern in buildings having wide openings.

Article
Full-text available
In humid tropical climates where the average annual temperature and the relative humidity are high, the air flows in buildings may be enough to provide ventilation at a satisfactory level of comfort without the use of active air-conditioning systems. Air movements have an effect on thermal comfort, decreasing the risk of local overheating, and givi...
Article
A new method is presented for the evaluation of interior velocity coefficients using artificial neural networks. The interior velocity coefficient gives a measure of the relative strengths of interior air movements in the horizontal plane representing an occupied space. Air movements in a building depend not only on the external wind velocity, but...
Article
This paper assesses the applicability of some architectural design elements to provide comfort ventilation in humid tropical regions: size and location of windows, building eaves and roof shapes for a single unit house. Most window and roof configurations are sufficent to produce only a slightly more comfortable level although they can certainly in...

In the first part of this paper, the authors present shortly the main tools used to predict airflow inside buildings. This description of the available tools allows to define the context in which they frame their works, the theoretical approach being unusual. The article deals with the exploitation of the so-called behavioural models, for the veloc...
Article
The effects of roof shape on wind-induced air motion inside buildings were analysed by using a numerical simulation: computational fluid dynamics (CFD). The average indoor velocity coefficient, a non-dimensional indoor air motion parameter, was used to calculate the relative strength of the interior air movement in the horizontal plane representati...

Article
The author found that the results obtained were reliable and indicates that neural networks can be used as a predictor for investigating window opening configurations to study the effects on interior air motion. Further study is needed in the development of the database to cover wider architectural parameters and the implementation of new types of...
Article
This paper presents an investigation into natural ventilation in the field of computational fluid dynamics using in particular rather rough mesh cells. The CFD results were then compared to the wind tunnel results obtained by Gouin at the Centre Scientifique et Technique du Bâtiment(CSTB) in Nantes. The role of eaves, and that of window configurati...
