Piezoelectric generation and Dynamo generation can be used as means of converting waste energy into electrical energy, which can then be processed and used to run various gadgets. An Electric Harvesting Tile has been designed and constructed in this research. Mechanical stress has been applied on a Piezoelectric plate via walking/running. The different configurations of the Piezo-plates determine the electrical output. The configurations used in this study require twenty-four Piezo-plates, configured with four banks in parallel to each other. Each bank consists of six Piezo-plates connected in series. This configuration allows maximum energy to be generated since placing the four banks in parallel increases the current produced. The six Piezo-plates in each bank are configured in series since when piezoelectric plates are connected in series, the internal resistance will increase, and the voltage will be more stable. Using this configuration, a comparison has been made between the weight applied at the center and the external boundaries of the tile. It has been discovered that the voltage, the energy, the power, and the current have been higher for the weight applied at the center of the Tile. This increase can be attributed to the fact that applying force at the center ensures that an even force is applied to all the crystals, thereby producing higher voltage. Force applied to other sections indicates a lower voltage reading because the pressure is not applied to all the Piezo-plates, since their configuration includes four banks in parallel and each one consists of 6 Piezo-plates in series. Therefore, if pressure is not applied to one of Piezo-plates in series then the entire bank is open and no voltage is produced. It has been also discovered that the total voltage stored in the capacitor is the highest with the largest force applied since increasing the force increases the displacement of atoms, resulting in a higher voltage produced. The energy generated has been stored in a rechargeable battery, which has been used to power a mobile device.

Retrofitting of existing buildings is one of the most effective ways to decrease building energy consumptions and reduce CO2 emissions, making buildings more comfortable and sustainable. This research aims at improving the energy performance of existing buildings through minimizing lighting, cooling, and heating loads. The study has used a real case data and energy efficiency simulation using IES-VE, a software package for building energy analysis and sustainable design. A single existing family building in Jordan has been used as a case study. The paper has studied many energy saving measures based on the economical value, the technological and the architectural features of the building, in order to show how related variables could improve the building’s energy performance. The research has studied variables like roof insulation, shading devices, and double-glazing. A combination of all the strategies has resulted in an efficient retrofit measure that has helped reducing energy consumption by an average of 40% annually, controlling heat loss, and gain. Roof insulation and shading devices have been the most efficient measures for reducing energy consumption in buildings while the PV has been the most efficient as energy saving. The results of this research have approved that studying retrofit scenarios on real case and have helped to provide real measurements and real impact of applying energy measures and how to develop simulation setting. It has helped developing guidelines and references for decision and policy makers, future investments and designer based on the research results. A matrix has been developed to compromise between initial cost, performance, feasibility, payback period of retrofit technologies, and finally installation process.

This paper presents the details of 13 rooftop PV systems installed at Philadelphia University (PU) in Amman-Jordan and gives an assessment of these PV systems in terms of the design layout that harmonize the university building’s roofs architectural style, and also in terms of energy generated compared with the university energy consumption using real data of the year 2019. Technoeconomic performance metrics and socio environmental assessment of the PV systems are also performed. The analysis shows that more than 99% of the energy needs of the university are met by solar energy. This energy generated is equivalent to 1587 metric tons of CO2 eq. This amount of CO2 avoided is equivalent to 26,236 tree seedings grown for 10 years. This emphasizes the main conclusion that Philadelphia University has taken the right decision with the installation of these systems that represent a great step towards the university sustainability.
