An Approach to Multi-Attribute Assessment of Indoor Environment Before and After Refurbishment of Dwellings/Daugiatikslio Gyvenamųjų Namų Vidinės Aplinkos Vertinimo Prieš Ir Po Renovacijos Būdas/ Комплексная Оценка Внутренней Среды Жилых Домов До И После Реновации
Abstract:Abstract. The paper analyses the correspondence between the present state of indoor environment and needs of habitants and the Lithuanian Hygienic Norm. To investigate the correspondence the authors (a) distinguish measures (attributes) of evaluating dwelling houses and their importance, (b) choose a method of processing the values of attributes, (c) choose a method of evaluating the efficiency of refurbishment and/or renovation of a building and (d) investigate dwelling houses in Naujoji Vilnia and evaluate t… Show more
“…Major energy inputs go to the construction and heating of premises, and therefore, as investigations have revealed (Nanazashvili 1990;Kazragis et al 2004;Kazragis, Gailius 2006;Zavadskas et al 2009), the aforementioned waste can be used for the production of construction composite products with enhanced thermal insulation properties. However, this requires an appropriate binding agent.…”
The article notes that not all types of plant origin waste are appropriate for being used as fuel or left for decay. The environment is polluted by noxious gas that is generated in the process of heating or decaying. Sulphur waste is produced at chemical and oil industry plants as well as during the treatment of emissions resulting from fuel combustion. Thermal energy is produced in the process of combusting plant origin waste; however, the emitted fumes are pollutants. A much more effective way for the use of this waste is proposed, i.e. to produce and use a new type of thermal insulation construction composites that would allow long-term heat saving buildings. The performed tests covered the properties of components and the influence of plasticisers on the plasticity and compressive strength of hardened sulphur. The common behaviour of sulphur and plant origin waste Á sawdust, boon, straw Á in composite was also analysed. All the properties necessary for thermal insulation materials were identified Á compressibility, compression and bending strength, thermal conductivity. They have the same value as other classical thermal insulation materials.

“…Simulations have previously been used to monitor building performance (Hong 2000) in areas such as renovation scheduling simulation (Lee 2012), and occupant evacuation planning (Yang et al 2005), etc. In addition, the majority of renovation research in existing buildings has focused on the multi attribute assessment (Zavadskas et al 2009), multiple criteria evaluation (Kaklauskas et al 2005;Zavadskas, Antucheviciene 2007), and decision support system (Kaklauskas et al 2008). Relatively little research simulates occupant movements in the function-space assignment of existing buildings.…”
Building renovation is an effective way to revive the use of a building, the use efficiency of which is primarily determined by its layout. However, in architectural practice, architects and building owners renovate buildings based on their personal subjective perceptions of how occupants use the building instead of systematically analyzing their use behaviors. This study proposes a model, called the Function-space Assignment and MOvement Simulation (FAMOS) model, which integrates radio frequency identification (RFID), fast messy genetic algorithms (fmGA), and movement simulation techniques to solve the function-space assignment problem. The RFID equipment is specifically used to track the occupants' movement data in a building, the fmGA is employed to identify the optimal result of function assignment, and the movement simulation technique is adopted to verify the result and support the decision-making of function-space assignment. This study presents a real case study to demonstrate the use of FAMOS and compare its assignments with those generated by a renovation architect. The objective function showed that FAMOS's version had a 14.80% higher objective value than the architect's version. The experiment also showed that FAMOS helped the architect find the best assignment or improve their assignment based on desired objectives such as preferred space size, minimized movement distance, or removal of corridor congestion.

Abstract.The main approaches which are applied to select the logistic center are the methods of gravity center, analytic hierarchy process, similarity to ideal solution, fuzzy ranking, assessment, etc. Multiple Criteria Decision-Making (MCDM) combines analytical and inductive knowledge, describing a domain problem, which can be fuzzy and/or incomplete. The fuzzy MCDM (FMCDM) approach can explain the problem more appropriately. The purpose of the paper is to select the most suitable site for logistic centre among a set of alternatives, to help the stakeholders with the performance evaluation in an uncertain environment, where the subjectivity and vagueness of criteria are described by triangular fuzzy numbers. The paper presents a newly-developed ARAS-F method to solve different problems in transport, construction, economics, technology and sustainable development.
