The article analyzes two different thermal modernization methods: the traditional method and the one using an innovative thermal insulating paint. During selecting the material, the main aspects were: material strength and durability, workmanship, the execution cost of a sample project, and the behaviour of materials during operation. All advantages and disadvantages of either of the external wall thermal insulation technologies are indicated. Cost calculation figures for the project under consideration carried out using the above-mentioned technologies have also been examined. It has been found that the technology using the innovative thermal insulating paint is fairly expensive and the obtained coefficients of heat transfer through the partition are not competitive compared to the traditional method using expanded polystyrene. However, by using the innovative technology for historic buildings, we are able to improve the aesthetic appearance of the facade and, at the same time, the thermal properties of the partition during carrying out a single project, while not spoiling the historical look of the building.","PeriodicalId":38397,"journal":{"name":"Scientific Review Engineering and Environmental Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48234424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, problems related to the ecological quality of the applied solutions require special interest. A method of solving these problems can be directly related to stakeholders involved in the projects. The role of a construction company in the context of decision making problems, and in particular its ecological responsibility, has become one of the fundamental elements of the genesis of this research. Linking ecological maturity of the stakeholders participating in the implementation of construction projects, and taking into account the environment friendly approach, related to the scarce resource management and the possibility of reducing their environmental impact, became the main goal of the article. The detailed objectives of the conducted research can be connected with promoting eco-friendly strategies among construction companies and increasing the awareness of construction entrepreneurs about the current EU requirements regarding the environmental issues of business. There is also a need for building ecological maturity of construction companies. Research conducted among the management staff of construction companies allowed to specify some factors of the ecological maturity in construction enterprise (EMCE) and their priorities.","PeriodicalId":38397,"journal":{"name":"Scientific Review Engineering and Environmental Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47987588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of a strategic assessment was to ensure the completeness of the assessment system of environmental impact in investment processes and to guarantee a consideration for the principle of caution in early stages of these processes. In the current legal situation, a strategic environmental assessment should anticipate a preparation of commune’s planning documents or making changes in such documents. In the case of local plans constituting minor changes of earlier-accepted documents, a strategic assessment is not made. As a result a strategic environmental assessment may be conducted in a limited scope in numerous communes. Additionally, a sketchy character and ambiguity of the regulations concerning strategic environmental assessments result in a lack of understanding for the necessity of conducting such assessments among investors and community. The aim of this article is to work out methods for strategic environmental assessment of the projects of local plans and to examine which methods of environmental impact assessment have been used in the prognoses of environmental impact, i.e. in the basic assessment documents. The research made shows that the quality of documents prepared for the need of strategic assessments is unsatisfactory in the aspects of methodology.","PeriodicalId":38397,"journal":{"name":"Scientific Review Engineering and Environmental Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68303319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
