Abstract Prefabricated buildings constructed to be used in a specific region cannot be assumed to work unconditionally in different climates around the world. It is important to develop passive house solutions for each location, suitable for the actual climate and geographic conditions. Shelters could be used in different applications such as refugee housing or telecommunication stations. Photovoltaic energy could cover the electricity consumption of these shelters. Shelters for different applications should be usable in all weather conditions, and because of that different climate zones were chosen. A full study about three climate zones was done to study the different factors that play a significant rule in choosing the location of the shelter. In this study, prefabricated housing was designed to ensure thermal comfort by doing structure design changes and using solar energy as an energy source. Three different locations have been chosen to be able to perform the best structure and components design for every location, taking into consideration the assumptions taken in each place. The total photovoltaic system was designed with a capacity of hot, moderate and cold climate zones with 2.0, 1.8 and 3.45 kWp, respectively, along with energy plus the production of 38% in the hot, 47% in the moderate and 28% in the cold climate.

In order to solve the problem of carrying out heavy loads up and down stairs for city residents who live in ordinary building without elevators, this paper designs a special small electric vehicle driven by storage battery, which has dual functions of climbing-stairs and driving over roads with a relatively quick speed based on a key mechanism—triple-wheel mechanism. The main structure and work principle of the small electric vehicle are given and analyzed at first. Then the driving speed over roads and the driving tortures of climbing stairs, which are essential data to design the powers of the driving motors, are calculated and analyzed. Finally the finite element analysis of the most fragile part-trident shaped part is analyzed and interpreted with a simulation model of the software—Solidworks. Due to the adequate and detailed calculations and analysis, the small electric vehicle with the dual functions designed by this paper can offer enough abilities to climb stairs with heavy loads and drive over roads with a considerable speed for residents who living in those buildings without elevators.

In the design process of building integration photovoltaic (BIPV), the architectural design, power system design and structure design are very important. Moreover, some kinds of suitable connection are required which should meet the requirements of bearing capacity and deformation. In this paper, the connections between photovoltaic system and buildings were discussed. Then based on the 1MW HIMOER photovoltaic support in Lianyungang technical college, we selected the suitable connection, and designed the space photovoltaic support .This results are useful for the development of the BIPV.

Purpose. Improving the principles of management of photovoltaic system with storage battery and with autonomous functioning during daylight hours for a local object, connected to the grid with multi-zone payment when excluding the generation of energy into the grid. Methodology. Modeling and analysis of energy processes in the photovoltaic system was performed using the Matlab software package. The simulation model of energy processes is based on calculated expressions taking into account the characteristics of the battery. Operability of the proposed solutions are confirmed on an experimental setup based on a standard hybrid inverter. Results. It’s shown, that due to the battery energy during the most loaded peak hours and part of the daytime the system operates autonomously and does not depend on possible violations of the quality of electricity in the grid. Scenarios of the recommended load schedule are proposed in accordance with the ratio of the predicted value of the daily energy generation of the photovoltaic battery to its possible maximum value. A simulation model of energy processes in the system with the correction of the recommended load value was developed. Originality. A method of the recommended load calculation with current correction for the actual generation and degree of battery charge is proposed, which allows taking into account differences the actual generation of the photovoltaic battery from its predicted value and the actual load from the recommended one. Practical value. The obtained solutions are the basis for the design of new and modernization of existing photovoltaic systems of local objects using software and hardware complexes for power consumption management.
