This paper analyses the energy performance gap between actual energy consumption and energy demand obtained during the dynamic energy simulation and building certification. To identify the energy performance gap, an existing office of energy efficiency class B was selected as a case study. The simulation program IDA Indoor Climate and Energy was used to create a dynamic energy model, based on the designed documentation and the actual indoor climate parameters recorded by the building management system. The results of the case study showed that the accuracy and reliability of the results presented by the dynamic energy model of the building directly depend on the assumptions. The correct values of the internal heat gains, indoor climate parameters, human behavior, air quality levels at different times of the day and season, HVAC system operation parameters and operation modes, specific fan powers of ventilation systems, the seasonal energy efficiency of cooling equipment and characteristics of sun protection measures have to be selected.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77619224","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}

Many countries are investing heavily in public transport to make it not only greener, but also more convenient, more attractive, faster, more competitive and more accessible. In order to promote a sustainable environment, private, public and non-motorized transport must functionally complement each other to form balanced integrated systems. There are currently two main forms of organizing public transport: a government-oriented service and a market-oriented service. Positive changes in the field of public transport are possible if in the process involves not only state and municipal institutions, but also infrastructure planners, passenger carriers and inhabitants. Public transport must be seen as a means of developing cities and regions. The aim of the article is to analyze the existing models of public transport organization and management, to compare them and submit a proposal, on the basis of which management model it would be possible to submit proposals for the improvement of the organization of Lithuanian public transport. Good foreign countries practice in the management and organization of public transport shows that in some countries public transport is already organized not by individual municipalities but by regions. Based on the achievements of foreign countries, municipalities are recommended to cooperate and share experience in creating a common public transport network. It is necessary to create a management scheme in Lithuania for the development of public transport services, which at the same time would reduce public costs.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76639714","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 student must describe the processor with the external components necessary for its operation in the specified HDL (hardware description language) language according to the provided specification during a certain number of projects. The weakness of this approach is that the basis of such projects is a processor of one specific architecture, so the lecturer faces the issue of individualization of projects. This article proposes a solution based on dedicated processors instead of one programmable processor of a specific architecture. It’s shown here that the issue of project individualization is easier solvable in the proposed way, and it does not deviate from the theory of computer architecture, because the programmable processor is a generalization of a dedicated processor. The article describes project design ideas based on dedicated processors and gives some examples.
