The research elaborates various solutions using detailed economic evaluation and energy efficiency calculation and simulation technology for formulating applicable, energy and cost-efficient retrofit solutions of single-family residential buildings located in temperate climate areas. Primarily the annual energy demand for a reference existing single-family residential building was determined. The economic analysis was performed for six formulated refurbishment scenarios in order to determine which of the scenarios will demonstrate optimal performance both in energy and cost efficiency. A feasibility study was performed for the most efficient scenario, which included an economic evaluation of low temperature radiant heating systems were three energy suppliers (oil, natural gas and electricity for air to water heat pump) were compared. According to financial analyses the optimal scenario includes the replacement of windows, installation of 15 cm expanded polystyrene thermal insulation, low temperature radiant floor heating, with a payback period of ten years.

Technical Measures

The paper focuses on analysis and assessment of economic effectivity of measures taken in order to lower energy demands of prefabricated panel residential buildings. For this purpose, a group of buildings with previously made modifications with potential to lower the energy and heating consumption were selected. Next, the development of their energy consumption and their costs was monitored. The assessment of achieved figures was made with regards to amount of costs which were paid for these measures and also with regards to their service life, amount of gained subsidy and decrease of consumed energies and operational costs of the buildings after the measures were taken. It was found that there had been a significant difference in investment returns for constituent technical measures. For some of them, it is not even realistic to expect reaching the return of investments during their service life period.

Abstract Residential buildings need demand of energy for both heat and electricity. However, it’s not always possible to meet this need by using individual panels due to the limited roof area. In addition, performing electrical and thermal energy production by using separate panels causes loss of performance and efficiency. The hybrid photovoltaic thermal (PV/T) collectors could be used in order to meet this necessity into the same collector. This paper investigates the performance and economic analysis of a PV/T collector for a building application in Turkey climatic conditions. For this purpose, the Matlab/Simulink model of the PV/T collector was prepared. The electrical and thermal performance of the PV/T collector has been investigated by changing various parameters on this model. In addition, market survey was conducted for economic analysis. 11 different input variables such as average daily irradiation, electrical and thermal efficiency, price of electricity and heating, operation and management cost, capital cost, debt to equity ratio, interest rate, discount rate and inflation rate are used to calculate the economic evaluation parameters such as net present value (NPV), levelized cost of energy (LCOE) and payback period (PBP). The results show that, the mean value of LCOE, NPV and PBP are 0.0467 €/kWh, 7905.3 € and 6 years respectively for the project size at 8.96 m2 which is consist of 7 panels in the 25 years life cycle. Also, the average electrical and thermal efficiencies are defined as 13.4% and 69.3% respectively during.
