Occupants' behavior exerts a significant influence on the energy performance of residential buildings. Industrial energy simulation tools often account for occupants' as monolithic elements with standard averaged energy consumption profiles. Predictions yielded by these tools can thus deviate dramatically from reality. This paper proposes an activity-based model for forecasting energy and water consumption of households and discusses how such an occupant-focused model may integrate a user-focused design of residential buildings. A literature review is first presented followed by a brief recall of the proposed modeling methodology and a sample of simulation results. The possible integration of the proposed model into the design and energy management processes of residential buildings is then demonstrated through a number of use cases.

Worldwide small-scale micro-CHPs account for the largest share in the fuel cell market by units of installation (not by installed power output). Notably, the Japanese Ene-Farm program is responsible for over 400.000 micro-CHP fuel cell installations (until the end of June 2021). This is the largest worldwide deployment program and it reflects the long- and outstanding commitment of both the Japanese government and the Japanese industry to form a ‘Hydrogen Society’. In Europe, the situation is entirely different. European projects like PACE financed by the European joint undertaking for hydrogen and fuel cells give a positive impulse for fuel cell based micro-CHP, however it has to be judged as insufficient for a market transformation measure. Presently, only Germany, notably by the KFW433 program, is providing frame conditions for a rollout of fuel cell based micro-CHP systems. This article analyses the success factors for the implementation of Ene-Farm systems in Japan. It compares the different frame conditions of Japan and European countries like Austria and discusses the question whether an Ene-Farm project based on the Japanese success factors could be replicated in Austria. On a bird’s eye, a European perspective will be derived from the analysis.

Requirements concerning energy efficiency of buildings, as well as the emission of energy sources working for their needs, are constantly growing. It is related to the Polish law, as well as European Union directives. It is obvious that in the coming years, further regulations and directives will impose additional requirements in this area. Therefore, the requirements for the operation of buildings and process of their designing are changing already today. In the past, the design process, in particular in the aspect of energy consumption, was based primarily on the procedures of static analysis of the building's structure (partitions, glazing, etc.). A typical calculation of a building heat demand did not take into account other aspects of the building's operation, such as user behaviour, heat gains or thermal accumulation of the building. Therefore, in modern designing, it is extremely important to use advanced computer techniques to develop a detailed balance of energy, which takes into account all its useful forms, including heat and electricity. Only such a comprehensive approach will render it possible to achieve the energy efficiency indicators required by law, as well as an economically efficient operation of the building, with a minimal bad influence on the environment. In general, the manuscript presents methods of comprehensive computer energy simulation of buildings, which can be used for optimal designing of buildings for any purpose. The article also presents an overview of available computer tools, which are recommended for the building design process. There are also some examples of using a simulation software for the analysis of residential buildings, along with the analysis of the results of energy simulations carried out with its help.

The most basic way to keep comfortable indoor environments for a building’s occupants and save energy for space heating and cooling in residential buildings is to insulate the building envelope. Among the building materials to be used, thermal insulation materials primarily influence thermal performance. In particular, the type, thermal conductivity, density, and thickness of heat insulator, are important factors influencing thermal insulation performance. We investigate the design status of residential buildings which were designed in accordance with the building code of Korea and selected the type of thermal insulation materials applied to the walls of buildings. The present study aims at measuring the thermal conductivity of thermal insulation materials used for building walls of residential buildings. In this study, after collecting the design documents of 129 residential buildings, we investigated the type and thickness of insulation materials on the exterior wall specified in the design documents. As the thermal insulation materials, extruded polystyrene (XPS) board and expanded polystyrene(EPS) board are used the most widely in Korea when designing residential buildings. The thickness of thermal insulation materials applied to the exterior wall was 70mm, most frequently applied to the design. We measured the thermal conductivity and the density of XPS board and EPS board. When the density of XPS and EPS was 30~35 kg/㎥, the thermal conductivity of XPS was 0.0292 W/mK and it of EPS was 0.0316 W/mK.
