    Decision making to support sustainable energy policies corresponding to agriculture sector: Case study in Iran’s Caspian Sea coastline
    (Elsevier, 2021) Pamucar, Dragan; Behzad, Masoud; Bozanic, Darko; Behzad, Moein
    Sustainable development programs rely on implementing energy policies in different sectors of a society. As far as agriculture sector is concerned, this paper intends to evaluate the current energy consumption and the potential for renewable energy programs’ deployment in regional scale. The candidate region is Iran’s Caspian Sea coastline. The assessment is modeled by recent multi-criteria decision analysis approaches, i.e. Level Based Weight Assessment (LBWA) with Weighted Aggregated Sum Product Assessment (WASPAS). The proposed index was designed so as to cover conventional and non-conventional energy resources subjects simultaneously, for instance: (1) biomass production, and (2) natural gas and diesel fuel at state level. From methodology point of view, the traditional WASPAS method is enhanced by the integration of the Weighted Power Heronian (WPHA) and Weight Geometric Power Heronian (WGPHA) functions. Application of these functions enables the elimination of the influence of extreme and unreasonable arguments in initial decision-making matrix. In addition, the interrelations between attributes is considered in the proposed model, that is particualrely appropriate for decision making in dynamic systems. The model capability in decision making has been investigated by comprehensive sensitivity analysis that implies in Iran’s Caspian Sea coastline, Mazandaran state ranks first, followed by Guilan and Golestan. The result is suitable for policy makers and regional managers to define proper plans and actions in sustainable development of Caspian Sea coastline based on both agriculture-based energy efficiency as well as bio-based energy potential.

    Experimental investigation and performance assessment of a solar-driven thermoelectric unit for localized heating and cooling applications
    (Elsevier, 2021) Koohi, Nima; Nasirifar, Sherwin; Behzad, Masoud; Cardemil, V D
    Heating, ventilation, and air conditioning systems help maintain the appropriate level of thermal comfort and air quality in buildings. To this end, the energy supply of these systems must be guaranteed. However, continuous efforts are required to improve the energy efficiency of this system and reduce greenhouse gas emissions. In the zero-emission building approach, the use of thermoelectric devices has been proposed to meet the heating/cooling needs in the building and help in flexibly changing the operating conditions according to the user's needs. In this study, an experimental setup was developed consisting of a multipurpose thermoelectric system that is directly powered by a solar photovoltaic panel. The heating mode was designed for space heating, whereas the cooling mode was tailored to an adiabatic box that could cool food and beverages. The results of this study will facilitate the practical use of this device in the future by directly connecting the thermoelectric system to the room and evaluating the response of the system to temperature changes requested by the user. This system has a high potential for delivering heating and cooling loads, achieving a coefficient of performance of 1.6 in the heating mode and 0.8–1.1 in the cooling mode. These results are promising given the current need to reduce negative environmental impacts in the building sector yet maintaining the same level of thermal comfort.
