“…Estimasi nilai payback period diperoleh angka 1,4. Payback period adalah metodologi yang digunakan untuk mengkalkulasi jangka waktu kumulatif modal investasi yang ditanamkan dalam usaha dapat kembali (Zhang et al, 2018;Susilowati dan Kurniati, 2018). Payback period sebesar 1,4 tergolong sangat cepat dibandingkan usaha agrobisnis sejenisnya, seperti budidaya ikan gurami yang memiliki PP 1,84 (Fattah et al, 2019).…”

Intensive aquaculture of vaname shrimp (L. vannamei), has been known to be a favorite for aquaculture commodities in Indonesia at the last 2 decades. The purpose of this study was to determine status of financial feasibility and business sensitivity rate in intensive shrimp culture activities. The research method used in this study is a quantitative method. The data analysis used to determine of financial feasibility and business sensitivity in the form of NPV analysis, Net B/C, R/C, IRR, and payback period. Also, an analysis of assumptions about rising feed prices and decreasing production revenues for the level of business sensitivity. The results showed that the shrimp culture business was categorized as feasible and profitable with NPV value of IDR 63,417,262,006, Net B/C 29.11, R/C 2.14, IRR 42.46%, and PP 1.4 years. Sensitivity analysis shows that the business is not so sensitive to the increase of feed prices and decreased revenue, but is very sensitive if both conditions change simultaneously, but are still in the financially feasible category. So, it can be concluded based on NPV, Net B/C, R/C, IRR, and payback period indicator analysis that intensive white shrimp farming is very feasible and profitable to use with a low level of business sensitivity due to feed price fluctuations changes and uncertain operational business revenues.

“…There is a lack of studies on such concepts, where PVs are used to produce heat energy and is integrated with seasonal storage in cold climatic conditions. In addition, there is a lack of studies and evaluations of such concepts for community scale applications with old buildings in Nordic conditions [70] and its benefits in terms of emissions reduction. The concept where PVs and heat pumps are integrated with the seasonal storage at the community-level that contains old buildings was studied in the present study in the Finnish conditions.…”

In Finland, old apartments (1980s) contribute toward emissions. The objective is to reduce CO2 emissions to reach Europe’s targets of 2050. Three different centralized solar-based district heating systems integrated either with non-renovated or renovated old buildings in the community were simulated and compared against the reference city-level district heating system. The three proposed centralized systems were: Case 1: photovoltaic (PV) with a ground source heat pump (GSHP); Case 2: PV with an air-water heat pump (A2WHP); and Case 3: PV with A2WHPs, seasonal storage, and GSHPs. TRNSYS simulation software was used for dynamic simulation of the systems. Life cycle cost (LCC), CO2 emissions and purchased electricity were calculated and compared. The results show that the community-level district heating system (Case 3) outperformed Case 1, Case 2, and the city-level district heating. With non-renovated buildings, the relative emissions reduction was 83% when the reference energy system was replaced with Case 3 and the emissions reduction cost was 3.74 €/kg.CO2/yr. The relative emissions reduction was 91% when the buildings were deep renovated and integrated with Case 3 when compared to the reference system with non-renovated buildings and the emission reduction cost was 11.9 €/kg.CO2/yr. Such district heating systems could help in meeting Europe’s emissions target for 2050.

“…Moreover, municipalities' support and pilots projects are needed to develop such solutions in Finland [56]. In addition, there is a lack of studies and evaluations where heat-pump and PVintegrated systems are studied in detail [57] for community scale application in Nordic conditions. Therefore, solar electricity (PV) based district heating systems are designed and analysed, both technically and economically, in the present study and compared against the solar thermal based systems.…”

Climate change is one of the biggest challenges at the present time, and to tackle such issue, solar energy and efficient buildings, in general, can be used. The goal is to design and optimize photovoltaic based decentralized district heating system and later compare it-economically and technically-against three different optimized typologies of solar district heating system in Nordic conditions. The photovoltaic based decentralized system consists of one centralized low temperature tank charged by photovoltaic and air-water heat pumps and a borehole thermal energy storage, while the decentralized high temperature tank charged by an individual water-water heat pump in each house. The centralized warm tank charges the borehole thermal energy storage. The other three systems are photovoltaic based centralized, roof-mounted solar thermal based centralized and roof-mounted solar thermal based decentralized district heating systems. In solar thermal based systems, collectors are used to directly charge the short-term storage tanks instead of the photovoltaics/heat pump combination. The proposed system is simulated using TRNSYS software. Lastly, purchased electricity and life cycle costs of the system are minimized using multi-objective optimization and the genetic algorithm. The results indicated that the decentralized photovoltaic based system outdoes all the other systems in terms of techno-economic performance. The purchased electricity can be reduced by 22% while at the same time life cycle cost can be reduced up to 40%, compared to the worst optimized system (solar thermal based centralized system).Moreover, the decentralized photovoltaic based energy system has a payback period of 9-27 years, compared to the solar thermal based system and the conventional single building-heat pump system, i.e. around 17-58 years and 15 years, respectively. The highest renewable energy fraction for heating can be close to 99% for this system. The decentralization and electrical based district systems are better in terms of life cycle cost, payback period and in terms of technical performance, compared to traditional single house and solar thermal based district heating systems.
