While evaluating the energy savings potential in buildings of different function we face the energy balance of current situation evaluation problem. Generally the data of energy flows quantities and the nature of their dynamics are agregated and do not reflect the indicators of the achieved microclimate. Therefore this article analyses the energy balance following the example of one-year data collection analysis in a company’s building complex. The investigated problem is evaluated by the system analysis approach, i.e. the analysed object system is divided into separate subsystems which have been simulated individually but considering the subsystems joint relations in the system. The methods applied in this work are heat and mass balance of separate subsystems and statistical analysis method. The statistical analysis was used for the evaluation of the statistical reliability of the accumulated indicators (temperature, relative humidity, etc.). Siekiant įvertinti energijos taupymo potencialą skirtingos paskirties pastatuose susiduriama su esamos padėties energijos balanso įvertinimo problema. Dažniausiai duomenys apie energijos srautų kiekius ir jų kitimo pobūdį yra suminiai ir netspindi komforto rodiklių. Todėl šiame straipsinyje kaip pavyzdį pateikiant vienos įmonės pastatų komplekse atliktą vienų metų duomenų kaupimo tyrimą analizuojamas detalesnio energijos balanso sudarymas. Vertinimas atliktas sisteminės analizės požiūriu, tai yra objekto sistema buvo skaidoma į atskiras posistemes, kurios buvo atskirai modeliuojamos energyPRO kompiuterine programa, atsižvelgiant į šių posistemių tarpusavio ryšį. Šio darbo metu taikyti atskirų posistemių šilumos ir masės balansų bei statistinės analizės metodai. Statistinė analizė buvo taikoma vertinant metus trukusių matavimų sukauptų rodmenų (temperatūros, santykinės drėgmės ir kt.) statistinį patikimumą.

AbstractThe paper analyzes, starting from the Integrated Management System, the role of automation, the role of the officer and the role of the Energy Management System on board the ship. The implementation of an EnMS establishes the structure and discipline of identifying energy flows, implementing management actions and, finally, applying technical solutions, which significantly reduce energy costs, reduce non-productive time in production, and reduce emissions. of Greenhouse Gases in the environment. The steps to be highlighted in the realization of energy management are analyzed.

More people, more organizations, more towns, cities, regions and countries for more reasons have found that over the last 30 years the arts, their broader culture and overall creativity has something in it for them in renewal and revitalization. Over the last decade there have been over a hundred studies of the economic and social importance or impact of the arts, culture, heritage, the recycling of buildings for cultural purposes, creative quarters and the creative economy across the world. Yet there is much more to the arts, culture and creativity in city development. Places in transition urgently need to develop an overall culture of creativity cu ing across all domains within which the arts can be significant. This can be a painful exercise as old certainties crumble and systems, like education, need rethinking. Yet this can unleash new social innovations, new business models and new forms of citizen engagement. Renewal and transformation together are a cultural project involving a shift in mindset and perspective. Creativity is a primary resource as it creates the conditions from which innovations can emerge. Within this the creative economy sectors, especially when aligned to the dramatic digitization dynamic, play a significant role in developing new products and services, generating jobs, anchoring identity and helping expression. Cultural activities and programming and the physical assets of places, their heritage and older industrial buildings are significant elements in the renewal repertoire.

Microbiological detoxification of hazardous organic pollutants is highly promising, but its reliable implementation requires a sophisticated understanding of several different substrate types and how they interact. This paper carefully defines the substrate types and explains how their interactions affect the bacteria's electron and energy flows, information flow, and degradative activity. For example, primary substrates, which are essential for growth and maintenance of the bacteria, also interact with degradation of specific hazardous pollutants by being inducers, inhibitors, and direct or indirect cosubstrates. The target contaminants, which often are secondary substrates, also have the interactive roles of self-inhibitor, inhibitor of primary-substrate utilization, inducer, and a part of an aggregate primary substrate.
