Abstract

High population growth, climate change and energy crises raised awareness in Indonesia especially in Yogyakarta Province which has already arrived at the extreme limit and has been made predominantly for high-rise building design. High-rise building integrated wind turbine is a technology that accelerates wind power from the building elevation. This paper investigated wind velocity on the high-rise building for wind power based on location (wind climate data analysis), building aerodynamic shape and wind turbine position. In the beginning of the study, numerous famous high-rise building was redesigned and simulated using CFD simulation to find the most effective building design. The redesign and simulation were then validated using wind tunnel experiment. Thispaper focuses on guidance resulting on wind power density of Yogyakarta Province to predict the wind energy. The prediction was then combined with best design of aerodynamic building. The result shows that building energy can be optimized through aerodynamic building design, wind turbine position and best geographic area and climate to achieve maximum wind power.

Abstract

A mounted wind turbine on the top of a tall building may provide high wind power in regions of high wind speed and low turbulence. The objective of this study is to evaluate wind speed on roof top models to optimize the wind turbine performance for power generation. Comparative analyses from three different roof top models were conducted. Computational Fluid Dynamics (CFD) simulation and wind tunnel testing were performed to evaluate the performance of wind turbine. Wind speed on the building model with a geometric scale of 1:150 was measured in CFD simulation then it was validated in wind tunnel test. Results presented in this paper suggest that an increase of wind speed could be achieved with ¼ circular shapes around the rooftop which can provide additional wind speed of 55.24%, respectively.

Abstract

Considering the magnitude of energy loss in building, development of energy saving methods appears to be essential. Daylight plays a significant role in designing energy efficient buildings and improving visual comfort for the occupants. Many daylight analysis methods have been developed in this area. Most of these methods focus on opening maximization. These methods unfortunately might reduce comfort since it causes direct solar glare. There is a need for a reliable lighting simulation model to control the lighting strategy in early stage design. This study proposes a strategy for visualizing daylight analysis of buildings by using Integrated Dynamic Model (IDM). IDM is a combination of design tools used during the conceptual phase for holistic classroom that considers the building’s energy usage, daylight distribution, and thermal indoor environment. The optimization focus is related maximize the performance of the building envelope design. The purpose of this paper are; firstly, providing a new strategy for visualizing the predicting daylight while respecting architectural integrity. The second purpose is to facilitate the designer for choosing window and envelope design alternatives during early stages. The third is to maximize the positive impacts of daylight. Lastly, hopefully IDM could present a simplified simulation and analyze method with the timely, accurate and efficient process.
