Abstract [en]

Significant investments are being made in the construction sector in order to raise the quality of the buildings and make them more sustainable and energy-efficient. The key aspect of these investments should be the purposeful optimization of the possible renovation and construction measures. However, this important matter usually is being pushed aside in favor of construction price and/or quality. Nevertheless, there are plenty of criteria that play a major role in building sustainable development.

The main purpose of this study is to present a tool that combines multi-criteria decision making (MCDM) methods and building certification systems in order to make weighted decisions in complicated construction tasks. For this, a decision making model was developed with a focus on sustainability, buildings’ life cycle, MCDM methods, and building certification.

The first section of this thesis, the introduction, discusses the importance of the investigated area, and the main objectives, tasks, and structure of the thesis.

A literature review is presented in Section 2 – Theory. The main works in the area of sustainability, LCA, building certification, and MCDM are collected to show their role and importance and how they interact in the construction industry.

Section 3 presents and discusses the main ideas and instructions of the proposed decision making model.

Section 4 (Methodology) introduces the main existing and proposed techniques that I have used to implement the study.

Sections 5 and 6 are the case studies, which demonstrate how the proposed methods can be used in practice.

Final conclusions and recommendations are presented in Section 7.

Abstract [en]

The paper presents a new multi-criteria decision-making technique to select criteria for building sustainability assessment. The methodology of building certification system is integrated with the multi-criteria decision-making (MCDM) methods. The criteria set for assessment is determined based on Swedish certification system Miljobyggnad. Criteria weights are determined by applying Analytic Hierarchic Process (AHP) method. Weights of criteria are calculated based on Saaty's judgement scale and new original scale, presented by the authors. ARAS (Additive Ratio Assessment) method (MCDM method) is applied to solve problem under investigation. The developed assessment method involves LEED system's criteria.

Abstract [en]

Nowadays modernization of multi-dwelling houses appeals greatly to those from landlords to politicians. The key problem that drives the issue is maintenance price, which mainly consists of two elements: (1) huge energy consumption during heating season, and (2) simultaneously rising greenhouse gas emissions from fuel combustion. Currently, most of the studies highlight particularly an economical aspect although on a global scale an ecological element becomes even more important. Hence the present paper combines both parts but mainly investigates an ecological compound, i.e. greenhouse gas emissions. Although it has been revealed that the binding targets of the Kyoto Protocol were very easily achievable for Lithuania, it is obvious that in the context of climate change a constant decline of emissions is necessary. Therefore, the paper seeks to establish an unconventional treatment of the Kyoto Protocol and its practical application on multi-dwelling modernization. The method aims at decreasing emissions significantly. The two scenarios have been investigated according to which modernization could help cut emissions by 8% or 20% of 1990 levels. Modernization scenarios were evaluated using multi-criteria decision making methods, i.e., COPRAS, WASPAS and TOPSIS according to which optimal option was revealed. The final results have revealed that a complete replacement of windows would help decline total emissions approximately by 30% and thus greatly fulfilled initial expectations.

Abstract [en]

The article describes typical apartment buildings built in Swedish residential areas in the '50s, '60s and 70's. Each of these buildings included calculations on the effects and investment cost of a number of renovation measures aimed at improving energy efficiency. By applying multi-criteria decision making methods Simple Additive Weighting (SAW), Multiplicative Exponential Weighting (MEW) and Complex Proportion Assessment (COPRAS), the preferences of building owners regarding renovation measures were studied. The study highlighted four important criteria, including the use of energy from district heating and electricity, investment cost and payback period. The owner preferences were found to have a major impact on the outcome of the study. These owners gave sufficient weight to renovation measures within a short payback period. Renovation actions falling out to be quite attractive are additional thermal insulation in the attic and heat recovery from exhaust air.

Abstract [en]

The paper describes model of dwelling selection, using fuzzy games theory. Two types of buildings are under consideration: traditional singe flat dwelling house and loft flat dwelling house. Four alternatives of heating system are taking into account: coal based, gas based, biomass based, and combined biomass and gas based systems. Alternatives are described by a criteria set. Values of the criteria are determined by simulation and according to the statistic. Fuzzy games are applied for decision aiding. The problem solution result shows that fuzzy matrix games theory is appropriate for such purposes.
