As the challenges associated with sustainability, urbanization, life quality and demography become more imminent, companies are adapting to the changing requirements by means of revised strategic approaches. Thus, enterprises are increasingly deviating from the traditionally absolute priority of maximizing total return for shareholders. While this priority is still important, businesses are also looking at the total societal impact (TSI), which represents a collection of measures and assessments that incorporate the economic, social and environmental impacts of their products and services [1]. This paper focuses on the compound influence that TSI may have within the energy domain. In particular, the business opportunities resulting from the Horizon 2020 funded project INVADE are being discussed but seen from the perspective of a socially responsible corporate strategy. Referring to discussions, analyses and undertaken initiatives this paper concludes that business models which incorporate environmentally friendly, local and social and fair energy are capable of accelerating business growth for the concerned companies.

Abstract —In response to local and global energy and health challenges, this paper presents the design and cost benefit of the implementation of Net-Zero Energy Housing (NZEH) to the existing villas in Qatar. Thus, this work determines whether the benefits outweigh the cost of the implementation of NZEH. There is uncertainty over the reliability of the presented cost benefit data in other countries as cost benefits differ from one place to another. A lack of empirical evidence has increased this uncertainty; particularly, a lack of evidence on the costs and benefits of a net zero and low emission housing option to private households. These costs include the cost of renewable energy technologies. This paper aims to bridge the research gap by applying cost benefit methods. Thermal insulation, solar power generation and solar water heating systems were modelled and lifecycle costing was applied to explore the costs and benefits across 25 years for net zero emission new house scenarios in Qatar. The average typical residential villa energy use establishes a baseline for determining energy and cost savings. A cost-benefit analysis was first performed at the subsystem level, house level and then at the country level and the results were in favour of the implementation of NZEH. Solar photovoltaic and solar water heating subsystems are designed in order to meet the hot water and electricity requirements of a typical villa. Thermal insulation was found to be non-beneficial due to the low electricity tariff in Qatar. Annual savings of 299 Qatari Riyals (QAR) per villa and 21 million QAR at the country level could be achieved if NZE housing is implemented. This is in addition to the numerous benefits of the utilization of clean and sustainable energy. If the initiative of NZEH is implemented to all types of residential and commercial units, Qatar would save a multiple of this amount with a significant reduction in related health

Abstract —Soiling significantly reduces the energy production of photovoltaic (PV) modules. The reduction is not only determined by the amount and composition, but also by the size distribution of the particles. This study investigates the particle-size characteristics of dust accumulated on horizontal and inclined glass surfaces used in PV modules. The accumulated dust is compared to the ambient airborne dust. Effects of tilt angle and wind speed are investigated. Variations in particle size over the glass surface are also studied. Dust accumulating on a photovoltaic module is finer than ambient airborne dust, except for a combination of forward tilt AND low wind velocity. For wind velocities large enough to initiate wind erosion the accumulated dust is finer than the airborne dust even in the case of forward tilt. For backward tilt the accumulated dust is always finer than the airborne dust. Reasons for the finer dust are the preferential accumulation of the finer particles in the wake of the module due to their lower response time compared to coarse particles and the preferential removal of the coarsest fractions by the wind. At forward tilt accumulated dust is finest near the leading and trailing edges of a module whereas at backward tilt the particle size distribution over a PV module is more uniform. Energy prediction models should incorporate these internal variations and the differences with airborne

19 doi: 10.18178/jocet.2019.7.2.504 Abstract—In this study, a transcritical CO2 based solar assisted trigeneration system for a dairy farm is analyzed. Performance comparison is made between an ejector based system (C1) and a conventional throttle valve based system (C2). A mathematical model of the system operating under steady state conditions is developed in Engineering Equation Solver (EES). The results are presented based on the consideration that the evaporator load for chilling of milk exactly matches with heating load in the process heat exchanger for pasteurization of milk. A parabolic trough collector is assumed to be used to heat the working fluid and an auxiliary heater is used to supplement the solar heat. The operating parameters are adjusted in such a manner that net power produced is always positive. The effects of turbine inlet temperature, ambient temperature, turbine inlet pressure and process heat exchanger pressure on overall COP, cooling COP and power cycle efficiency are analyzed. It is observed that compressor power input required in C1 configuration is about 45% lower than that required in C2 configuration. Increase in turbine inlet temperature marginally affects the power cycle efficiency for both the configurations. Cooling COP reduces significantly with increase in ambient temperature for both the configurations. This study provides a basis for the feasibility of trigeneration systems in dairy application where simultaneous heating and cooling are required in addition to small amount of electricity for parasitic loads such as lights, fans etc.

Driven by decreasing PV and battery installation costs and mismatch between household demand and PV generation, household PV-battery systems are going to be deployed in the country and create significant implications for utilities in Thailand. This paper mainly discusses both negative and positive impacts of household PV-battery systems on Thai utilities. The use of household batteries (storing excess generation from PV during daytime and discharging it in the evening) can increase solar capacity values and energy values to power system, mitigate the problem of “duck curve” and decrease PV integration cost. Household customers can consume more PV electricity (increasing PV self-consumption ratio) from the inclusion of batteries. As a result, it leads to higher revenue losses and lower re-sale of exported electricity from PV to distribution utilities, while it is not the case for generation/transmission utilities since re-sale of exported electricity is only relevant to distribution power system and revenue losses of generation/transmission utilities remain unchanged. This is because with household batteries, the level of PV installation is the same (only shifting the consumption of household PV excess generation from daytime to evening). Therefore, it is necessary to precisely quantify each cost and benefit component in order to understand values of household batteries to the power system.

Abstract —Photovoltaic (PV) technology is one of the upcoming leading technology to curb environmental issues without affecting sustainable development. However, its efficiency and cost are the significant issues in getting its peak in energy sector. In this paper we have numerically investigated the effects of metallization on the performance of PV cell. By using Griddler2.5 software various designs of H-pattern PV cells have been studied. It is revealed that increase in the number of busbars augments the shading factor from 4.11% to 8.75% and fill factor increases from 69.39% to 81.06%. Moreover, it is found that efficiency of PV cell increases when busbars value reaches to 4, then it decreases, it may be due to the influence of shading. Similarly, as the size of busbar increases so does the shading factor increase from 5.05% to 12.54% and fill factor from 80.29% to 80.49%. While in this case efficiency decreased from 19.91% to 18.17% throughout sizing range of busbar in the study. Hence it found that thin metallic busbars are more beneficial for PV cell performance and optimal number of busbars to be used in a PV cell is

The use of passive thermosiphon solar water heating (SWH) is a cost-effective renewable source of energy for hot water production in Mauritius, given the relatively high solar yield year round. However, unavailability of sufficiently hot water for early morning use has been reported in households, confirmed by a survey undertaken, which may be due to improperly sized tank and/or collectors. Backup gas or electric heating is normally installed to cater for this problem. This paper presents the research work performed to analyze the dynamics of hot water production, consisting mainly of monitoring the temperature of the water inside the tank of an actual SWH in operation with the objective of characterizing the factors affecting hot water production. The temperature of the hot water inside the storage tank was found to fluctuate during the day and with consumption of hot water, and the mixing of mains cold water with the hot water was deemed to be a major factor leading to the shortage of hot water the next morning. Based on the analysis, a passive thermosiphon SWH in use in a household was modified by adding a second hot water tank with associated solenoid-actuated valves modulated by a microcontroller to regulate flow between the two tanks and to the end use point according to an appropriate rule set. The results show that hot water production can be optimized in currently installed SWH systems with the proposed design without back-up heating systems, thus providing an effective retrofit solution to systems in use.

The aim of this study is to analyze how the growth of renewable energy in the power market is affecting workers health and what are the cost implications of having a healthier workforce. To tackle this issue, Big Data from occupational health surveillance carried out to over 4,000 workers in Spanish companies is used to unveil hidden patterns and relevant factors affecting workers health. Machine learning is used to create a predictive Bayesian model in order to seek out relevant patterns that allow to design more effective prevention plans. The results obtained shed light on the positive impact that an increasing renewable generation of electricity can produce to workers health in the electric industry. Skin problems are the main pathology identified, where nervous system diseases are found to be reduced for renewable generation workers.
