W pracy przeprowadzany został przegląd różnych koncepcji magazynów energii cieplnej zintegrowanych z budynkiem mieszkalnym. Przedstawione zostały warianty różniące się między sobą pod względem kształtu, rozmiaru, wypełnienia, sposobu instalacji itp. Opisany został sposób zintegrowania systemów magazynujących z odnawialnymi źródłami energii. Następnie wskazane zostały inne rozwiązania projektowe umożliwiające redukcję zapotrzebowania...

The area of research and method of measurement are explained. In the second part of paper the results of tests and measurements are described. Emphasis was placed...

This paper overviews applied methods to evaluate energy consumption in Industry. The most important law regulations are presented, which decide on the necessity to conduct an effec - tive energetic economy. Basic assumptions are defined to calculate direct and cumulative energy consumption. The pros and cons of using each method are presented.

The paper presents modeling and simulation of energy consumption of two types of parallel applications: geometric Single Program Multiple Data (SPMD) and divide-and-conquer (DAC). Simulation is performed in a new MERPSYS environment. Model of an application uses the Java language with extension representing message exchange between processes working in parallel. Simulation is performed by running threads representing distinct process...

In this chapter, we show a study of energy consumption during execution of SPMD and DAC application – the same applications which time of execution we modeled in the previous two chapters. We measured an average power usage at a single node of the GALERA+ cluster during application execution and then we modeled the total energy consumption by the application. Next we simulated the applications using MERPSYS and we compared the...
