ABSTRACT:When looking for new uses for unused areas and buildings, it is essential to consider the context of the area, especially from the territorial-technical, spatial, socio-demographic, economic and urbanistic points of view. In order to find new uses for brownfields which will be sustainable in the long term, it is necessary to employ tools that enable holistic evaluation of the mutual relationship between brownfields and their surroundings so that the most suitable future use can be identified. In the present contribution the brownfields in the Liberec Region (Czech Republic), which is known for its ragged terrain and distinct industrial past, were subjected to this evaluation. Methodically, the contribution is based on principal component analysis and variance analysis (20 composed factors). The results indicate that in several cases apparent differences in the environment of neglected areas can be observed, whether based on previous use or between regenerated sites and sites falling into disrepair. The results of the performed tests show that the environment where brownfields occur differs in some cases, especially when comparing the past and present uses and the current state of their regeneration.
