Sustainability assessment for recreational buildings

ABSTRACT A large amount of natural resources and energy is wasted during and after the building construction process which might cause environmental problems such as climate changes. In order to achieve higher standards of environmental protection a range of building assessment systems has been established. However, they are mostly connected with the efficiency of an environmental protection and consumption of resources. Only few of them have limited possibilities to assess social and economic sustainability. A sustainable building includes aspects of environment, economy and society and therefore requirements to its assessment systems should be complex. We suggest that sustainability principles, that is, environmental, social and economic sustainability, should be estimated in the same equal weightings. The authors of this article created a model for assessing the sustainability for recreational buildings. Our model was created, in collaboration with experts, using breakdown, compensation and the analytic hierarchy process methods. The sustainability of Druskininkai Snow Arena (Lithuania) was assessed using a sustainability assessment system based on the proposed model.

Formation of a system of multicriteria indicators for the assessment of office leasing options

With the growing scope of business and the internationalization of companies, office leasing is becoming an increasingly relevant issue. It has become an integral part of business and affects the results of commercial activities. The methods for the assessment of office leasing options that are available at the moment are imperfect, as they lack complexity and they are not related to the objective of the lease — the improvement of business results, imperfect methods for a quantitative assessment of the lease options, etc. The adequacy of the assessment of lease options largely depends on the system of indicators that is used. The system is formed on the basis of a list of indicators composed from different sources. For the system of indicators to fully reflect the analyzed phenomenon and to be suitable for a quantitative assessment, there have to be not too many or too few indicators in the system. This means that the indicators that are insignificant have to be eliminated from the list. The most precise way to do that is to apply methods of mathematical statistics. The research is based on the analysis of scientific literature and the methods of mathematical statistics.

Ranking of office lease options by multi-criteria methods

Abstract Due to the growing scales of business and internationalisation, the issue of the office lease is becoming more and more relevant for companies. They are becoming an inherent part of business, on which the results of the commercial activity depend. Currently existing methodologies for the assessment of the office lease options are imperfect as they lack complexity; they are not associated with the objective of the lease – the improvement of the business results; the methods of the quantitative assessment of lease options are far from perfect. The paper aims at formulating the hierarchical indicator system of commercial real estate facilities (offices) adjusted for the multi-criteria assessment and at calculating the lease options based on this indicator system. To achieve this goal, the following methods have been used: scientific literature analysis and multi-criteria assessment methods.
