Abstract

The objective of this
study is to suggest a mathematical model and an optimal algorithm for
determining the height of apartment buildings to satisfy the solar
rights of survey buildings or survey housing units. The objective is
also to develop an automatic computation model for the optimum height of
apartment buildings and then to clarify the performance and expected
effects. To accomplish the objective of this study, the following
procedures were followed:

(1)
The necessity of the height planning of obstruction buildings to
satisfy the solar rights of survey buildings or survey housing units is
demonstrated by analyzing through a literature review the recent trend
of disputes related to solar rights and to examining the social
requirements in terms of solar rights. In addition, the necessity of the
automatic computation system for height planning of apartment buildings
is demonstrated and a suitable analysis method for this system is
chosen by investigating the characteristics of analysis methods for
solar rights assessment.

(2)
A case study on the process of height planning of apartment buildings
will be briefly described and the problems occurring in this process
will then be examined carefully.

(3)
To develop an automatic computation model for height planning of
apartment buildings, geometrical elements forming apartment buildings
are defined by analyzing the geometrical characteristics of apartment
buildings. In addition, design factors and regulations required in
height planning of apartment buildings are investigated. Based on this
knowledge, the methodology and mathematical algorithm to adjust the
height of apartment buildings by automatic computation are suggested and
probable problems and the ways to resolve these problems are discussed.
Finally, the methodology and algorithm for the optimization are
suggested.

(4)
Based on the suggested methodology and mathematical algorithm, the
automatic computation model for optimum height of apartment buildings is
developed and the developed system is verified through the application
of some cases. The effects of the suggested model are then demonstrated
quantitatively and qualitatively.

Keywords: Solar rights; Solar access; WALDRAM; Apartment buildings; Optimization

[프로그램등록] Visual Air (software for psychrometic chart)

April 20th, 2010

공기의 물리적인 상태값은 공기와 관련한 수치계산의 기본이 된다. 공조 설비에서 취급하는 공기는 습공기이기 때문에, 공기조화에 관한 계산은 습공기의 성질을 충분히 파악한 상태에서 가능하다. 이런 습공기의 상태값에는 밀도, 수증기압, 절대습도, 상대습도, 노점온도, 습구온도 등과 함께 습공기가 안고 있는 열량인 엔탈피가 있다.
습공기의 상태값은 표로 제시되기도 하지만, 모든 경우에 대한 자료를 주지 못한다. 이에 가장 기본적인 자료로서 습공기선도를 사용하게 되는데, 습공기의 상태값을 구하는데 사용됨과 동시에 공기조화 프로세스를 설계, 해석하는데도 사용된다.
따라서, 습공기에 대한 이론적인 것을 살펴보고, 상태값을 계산하는 함수와 함께 습공기선도를 그리는 함수를 작성하는 프로그램을 만들었다.
프로그램 제작은 사용자 인터페이스가 좋은 윈도우 환경에서 쓸 수 있게 Visual Basic 6.0 Professional Version으로 하였다.

참고문헌

Environmental issues have been taken into considerations in housing design for a
few decade. Pursuits for comfortable environment have been increased from
sunshine duration to views recently. This implies that evaluation tool consists
of various three-dimensional information. And it is devoted to support
decision-making at the design stage. Therefore it is important to present
environments visually which will be made by building geometry. In order to
evaluate solar access, irradiance, and views, various spherical projections were
also developed and applied to site analysis.
