“…Discount rate depends on the interest rates set up by national central banks. As a consequence of 365 energy‐efficient measures applied to a public historical building in Turkey and a sensitivity analysis performed to detect the cost optimal energy calculations with considering the inflation rate, different interest rates, and calculation periods demonstrated that a reduction in economic parameters decreased the cost effectiveness in the scenarios having high initial investment costs, while application of two passive technologies to office building located in the town of Bragança, Portugal with using the real discount rates of 3 % and 1 % illustrated that the financial profitability depends on discount rate used in the analysis very much [30, 32].…”

The improvement of energy efficiency in buildings is one of the most important factors of the energy policy of Turkey owing to its energy import, especially of natural gas. Çorum city, one of the colder cities of Turkey that uses a high amount of natural gas as fuel for heating, was selected to demonstrate the reduction in energy loss and carbon dioxide emissions of buildings and to contribute to the insulation sector in the Çorum industry. Therefore, two different methods, namely, the Turkish standard 825 and heating degree-days, are applied in cost-optimal methodology, using four types of traditional insulation materials, namely, standard expanded polystyrene, neopor (graphite-added expanded polystyrene), extruded polystyrene, and stone wool, and two state-of-the-art insulation materials, aerogel and vacuum insulation panels in two types of reference buildings comprising hollow brick and pumice stone walls. As a consequence of application of the Turkish standard 825 and heating degree-days methods in the cost optimal methodology of the European Energy Performance of Buildings Directive with the utilization of the optimum insulation thicknesses of six types of insulation materials calculated from both the Turkish standard 825 and heating degree-days methods at four different types of windows and one top side measure, a new methodology was developed. Results obtained from three methodologies are compared based on insulation materials and wall types.Keywords: Turkish standard 825 / heating degree-days / cost-optimal methodology / wall types / insulation materials Die Verbesserung der Energieeffizienz in Gebäuden ist aufgrund des Energieimports, insbesondere von Erdgas, eine der wichtigsten Faktoren der Energiepolitik der Türkei.

Office buildings built before the pre-1960 age constitute a relevant group for analyzing the energy performance of the Portuguese building sector. A dynamic energy simulation was used to assess the energy performance of an existing office building located in the town of Bragança, Portugal. By using a staged renovation approach, two passive technologies applied to the building envelope and an efficient domestic hot water system were selected and a financial evaluation through the net saving (NS) method was undertaken to choose the best efficiency measures/packages for improving the building’s energy performance. Real discount rates of 3% and 1% were used in the financial evaluation. Considering the real discount rate of 3%, the results showed that only two out seven retrofit options had a positive financial return. By using the real discount rate of 1%, all retrofit options were found to be financially efficient. The results of the study corroborated those of earlier works that found that the financial profitability of energy renovation investments is very sensitive to the discount rate used in the analysis. The results of the study also suggested that the staged renovation approach used in the analysis is economically feasible, and that this approach is an alternative to one-step renovation approach to help to achieve the country´s energy and climate targets by 2030. Suggestions for future research conducted for office buildings in the different climate zones and other age groups in Portugal are proposed.

Implementing energy efficiency measures in a building helps to save 60% of primary energy and 40% of overall cost [4]. Energy efficiency strategies or measures are subdivided into two categories, namely passive measures and active measures.…”

The energy consumption of the building sector has heightened significantly in recent times owing to rapid global urbanization. Energy efficiency measures (EEM) may become a legal obligation for construction in years ahead. This study proposes the execution of Active Energy Efficiency Measures (AEEM) in a hospital building model evolved in energy simulation software while designed for a warm and humid environment. A series of design models were developed for the study by considering temperature set-points, HVAC star rating, and roof area for solar plant as the varying parameters. Investors have been reluctant to adopt efficiency measures attributed to the rise in their capital costs. Therefore, the study performed a Lifecycle Cost Analysis (LCCA) and payback period computations for additional investments to implement EEM. The findings are presented in the form of a correlation study between percentages of annual energy savings, life-cycle cost reductions, and additional capital investments for the implementation of AEEM. Energy conservation strategies without any additional investments to obtain a good future return are also discussed. With the combination of varying parameters, energy savings of up to 38.66% and a reduction in Lifecycle Cost (LCC) of up to 17.25% are obtained. Comparisons of design models highlight the importance of performing energy simulations and LCCA prior to actually making an investment in energy efficiency strategies.
