“…Also, Imam et al [18] reported that grid-connected PV installation in a typical residential building in Saudi Arabia is feasible, based on several techno-economic indices obtained from the SAM software. Furthermore, other authors affirmed the technical and economic feasibilities of rooftop solar PV designs [19][20][21][22] and floating PV designs [23,24] for specific locations around the globe.…”

This paper was aimed at the techno-economic feasibility assessment of a 25 MW solar photovoltaic (PV) system for electricity generation in Effurun-Warri, Nigeria. The system advisor model (SAM) software was used to design and simulate the solar PV modules for power generation. Furthermore, the standard and validated models inbuilt in the SAM software were employed to analyze the techno-economic performance of the system and the energy losses. Results showed that the extent of energy losses considered in the design of the PV system had significant effects on system performance. For the 25 MW system assessed in this study, the highest monthly energy production was obtained at 3.9 GWh in January and the lowest at 1.9 GWh in July. Also, the total annual energy produced by the PV system was observed to depreciate as the system ages, with about 12% of the initial annual energy production expected to be lost after 25 years of system operation. The obtained capacity factor (12.1 %) and the performance ratio (0.75) revealed that the PV system in its current design would be inadequate to match the energy demand profile of Effurun-Warri, Nigeria. Additionally, the levelized cost of electricity (LCOE) was obtained as 0.65 cents/kWh for the system, which is about 85% higher than the current price of electrical energy in Southern Nigeria. Moreover, a negative net present value (NPV) was obtained for the plant, all indicating that the cost of investment would not be offset during the lifetime of the system, and the project would therefore not be profitable in its current design.

In Europe, it is estimated that 14% of existing buildings were built before 1919, whereas 26% were built before 1945. In Romania, about 31% of the buildings date from before 1961, contributing to the current stock of old buildings with historic and architectural value in the country. This paper illustrates the current state of buildings with historic and architectural value in Romania, alongside a case study of a representative administrative building in Câmpulung, Romania. The analysis of the Town Hall building in Câmpulung, Romania, demonstrates that potential energy savings of up to 47.53% can be achieved by implementing interventions such as upgrading windows, insulating the attic, and installing photovoltaic panels. The highest energy reduction is obtained by replacing the window glass with a value of 18.16% with attic insulation with a value of 16.1%. This paper also presents indoor measurements of temperature and humidity in different offices positioned in the north and the south. The study conducted on the south façade office revealed consistent temperatures ranging from 21.7 °C to 24.4 °C, with an average of 23.31 °C. However, the humidity levels fluctuated considerably, ranging from 17.1% to 39.1%, with an average of 26.89%. The sun-exposed section of the building saw relatively stable temperature conditions, but the varying humidity levels could have a detrimental impact on the quality of the indoor atmosphere and potentially decrease the effectiveness of the workforce. By contrast, the north façade office exhibited lower and more fluctuating temperatures, ranging from 19.8 °C to 23.6 °C, with an average of 21.74 °C. Additionally, it had higher and more stable humidity levels, ranging between 19.5% and 41.7%, with an average of 29.83%. A thermographic analysis was performed on the north façade of the Câmpulung Town Hall, utilizing thermal imaging technology to detect areas of heat loss, and thus identifying the energy inefficiency problems of the building’s exterior. The investigation found notable variations in temperature, especially around the windows, where temperatures could be as high as 14.1 °C, highlighting the insufficiency of the building’s antiquated timber-framed windows in preventing energy loss.
