“…Jia [13] proposed changing air conditioning units for others with better COP in an office building in Hong Kong. Alireza et al [14] changed the facades of an office building situated in Teheran with improved construction materials. Fathalian et al [23] suggested the energy retrofitting of opaque vertical enclosures in an office building in Semana (Iran).…”

“…The result was that, with the change in water-cooled air conditioning units, a higher COP was achieved; this, along with shading techniques in windows, could reduce energy consumption in commercial buildings by about 36 W/m 2 to 24 W/m 2 , i.e., by 33% of total consumption. Alireza et al [14] carried out a study in an office building in Tehran; the building was modeled and simulated using DesignBuilder in order to carry out the analysis of the thermal energy performance of the building. It was determined that, due to its conventional construction materials, energy losses were higher than normal.…”

The application of energy-efficiency strategies in buildings is a hot topic around the world; in some countries, there are regulations with more or less degree of compliance, but in most countries located in the tropical zone, there are no regulations, and it is not easy to transfer regulations of countries outside of tropical zone. For countries located in tropical zones, the implementation of strategies to reduce the heat flow from outside to inside buildings is a key point. As a case study, the Dominican Republic (DR) was chosen, and during 2020, an analysis focusing on buildings of the tertiary level was carried out with the goal of using scientific methodology focused on tropical climates that allows for a significant reduction in energy consumption by implementing Energy Efficiency Strategies (EESs) that are available, with minimal intrusion into the building and low cost. The study includes, as parts of the proposed methodology, the characterization of building parks, including the climatic zonification of the country, an in-depth study of the building typologies in DR, and a massive survey around the country about the technical characteristics of air conditioning units and their usage; the election and characterization of buildings, including simulation and validation throughout the monitoring of eight different buildings; ananalysis of the measures of energy efficiency and implementation in the models, including the election of a demonstrative building, the election of the most convenient EESs, modeling of EESs, implementing EESs in the building, monitoring, and validation; and ananalysis of the impact of the measures at the region or country level, throughout which important conclusions can be obtained in order to reduce energy consumption in the country. The results show that this methodology is a valid tool for countries situated in tropical areas in order to reduce the energy consumption associated with air conditioning units with low cost, availability, and no intrusive EESs.

“…The results became guidelines to develop and integrate renewable energy systems for newly built buildings as a decision-making tool, as it could be for existing buildings to achieve better energy efficiency. Pirmohamadi et al ( 2021 ) simulated existing office buildings to decrease energy usage and increase the building’s energy efficiency. The simulation employed a solar thermal system to reduce the building’s CO 2 emissions by using the DesignBuilder software.…”

Energy management plan is utilized as an optimum strategy by using solar and wind energies, as a new preliminary implementation. The aim of the study is to create an optimum strategy through an optimization of an energy management system. The study implemented an onsite model, two numerical approaches, and an optimization analysis on a Mediterranean port. Two approaches have been used: solar energy is applied experimentally and numerically, and then wind energy is simulated. An optimization analysis integrated the two approaches together to control their operation. The results showed the installed solar panels provided sufficient generated power for the buildings. Also, the simulated wind arrays showed good behavior with increased power coefficient for the wind turbines, for future implementation. These results were validated using the DesignBuilder software and showed accurate values regarding the experiment for solar panels and CFD simulation. Eventually, a Pareto optimality analysis is applied between the solar and wind energies to reveal an energy management plan. Renewable energy offered energy to support the consumption of the port’s buildings.

“…The literature suggests that building-integrated solar PV modules have great potential for transforming energy systems [12][13][14], and their application is widely studied for DH in the context of Latvia [15]. The authors of [16] concluded that solar PV with battery storage can be installed in 10% of all households in Latvia without any support policies if electricity prices remain the same.…”

This study aims to compare the technological solutions that can contribute to more sustainable energy use in the residential sector. Specifically, the goal of the study is to evaluate the environmental impact of different energy (heat and electricity) supply technologies applicable for an average size single-family building in Latvia, a country known for climatic condition characterized by cold winters with frequent snowfall. The study applies the lifecycle assessment methodology of ISO 14040 and the impact assessment method known as ReCiPe 2016 v1.1, which has not been used before for the scope addressed in the study in the context of single-family building energy supply technologies for climatic conditions in Latvia. Thus, the results of the study will provide new information for more sustainable energy solutions in this area of study. The technologies included in the defined scenarios are conventional boiler, electricity from the grid, Stirling engine, and solar photovoltaics (PV). The results of the lifecycle impact assessment for damage categories revealed that all scenarios have a high impact on human health due to fine particulate matter formation followed by global warming. Regarding the damage to the ecosystem, the terrestrial ecotoxicity category has highest impact, followed by global warming. Sensitivity analyses affirmed the model’s validity and also showed that the impacts of conventional systems were most sensitive to changes in electricity consumption, and therefore, the scenarios with electricity supply from a Stirling engine or PV can be considered a more robust solution under changing electricity demands from an environmental perspective.
