Crime Prevention through environmental design(CPTED): Current state and Improvements of Government Office Buildings

Abstract

The purpose of this study is to investigate government office buildings and the environmental factors that contribute to crime preventative designs of those buildings. It has been found that: first, in the case of central government buildings, “access management of government buildings” and “protection diagnosis” were newly established in the ｢government building management regulations and enforcement regulations｣ in December, 2016. However, this change has yet to be established in local government buildings. In addition, it was confirmed that the contents of regulations reflected here were far below par compared to the crime prevention building standards applied to personal apartments under the ｢Building Act｣. Second, as rallies and protests that take place near government office buildings increase every year, surveys confirm that exposure to noise has a negative impact on work performance. Finally, it is crucial that crime preventative designs should be strictly controlled by regulation (ex. building codes), so that civil servants are protected from crimes. It is necessary to improve sound insulation performance of windows to minimize the noise generated by protests to not hinder the work performance of civil servants. These findings help understand the current environmental conditions of government office buildings associated with crime prevention facilities. There is room for improvement in the principles and process to make the government office building better, safer and more pleasant for both citizens and officials.
