“…However, there are solutions to this problem. For example, roof space can be utilised within cities to supply this space without using limited open spaces within cities which works for Egypt [25,26]. Another solution to the large area that solar panels require to be effective is to use otherwise unused space or isolated regions [27].…”

In this study, an analysis is carried out to determine the optimal application of multiple renewable energy resources, namely wind and solar, to provide electricity requirements for green smart cities and environments. This was done to determine the potential of renewable energy to provide clean, economically viable energy for the case study of Zagazig, located at 30°34′ N 31°30′ E in the North East of Egypt. The relevant data surrounding the production of energy were collected, including the meteorological data from NASA, and specifications regarding renewable resources including solar panels, wind turbines, and storage batteries. Then a hybrid model was constructed consisting of Photovoltaics (PV) panels, wind turbines, a converter, and storage batteries. Once the model was constructed, meteorological data were added alongside average daily demand and cost of electricity per kWh. The optimal solution for Zagazig consisted of 181,000 kW of solar panels feeding directly into the grid. This system had the lowest Net Present Cost (NPC) of the simulations run of US$1,361,029,000 and a net reduction of 156,355 tonnes of CO2 per year.

“…The poor performance of some of these technologies is also pointed out as a barrier, normally focusing on photovoltaic installations. This forces an increase in the surface area to be installed when the space of the building envelope is insufficient and/or inadequate to generate all the necessary energy [87,102], although they do affirm that they can help reduce the electrical energy consumed from the network, reducing expenditure [103].…”

Exploring the Critical Barriers to the Implementation of Renewable Technologies in Existing University Buildings

et al. 2021

For more than a decade, the European Union has been implementing an ambitious energy policy focused on reducing CO2 emissions, increasing the use of renewable energy and improving energy efficiency. This paper investigates the factors that hinder the application of renewable energy technologies (RETs) in existing university buildings in Spain and Portugal. Following a qualitative methodology, 33 technicians working in the infrastructure management offices of 24 universities have been interviewed. The factors identified have been classified into economic-financial, administrative and legislative barriers, architectural, urban planning, technological, networking, social acceptance, institutional and others. It is concluded that there have not been sufficient economic incentives to carry out RETs projects in this type of building. Conditioning factors can act individually or jointly, generating a greater effect. Most participants consider that there are no social acceptance barriers. Knowledge of these determinants can facilitate actions that help implement this technology on university campuses in both countries.

Building envelopes can play a significant role in controlling energy consumption, especially in hot regions because of the wide variety of envelope materials and technologies that have been developed. Currently, because of the high rise in energy prices, especially with the high demand of fossil energy in the building sector worldwide, using curtain walls for maintaining adequate lighting in public buildings could lead to higher energy consumption because of the continuous exposure to the sun in hot regions. For this reason, studying the use of renewable or smart alternatives in the building sector to ensure a cleaner, greener environment by deploying sustainable technology in order to reduce energy demand and support economic long-term solutions would be important for solving such a problem. This paper aims at studying the use of renewable energy technologies and alternatives; represented in new building integrated photovoltaics (BIPVs) technology that could be integrated within building skin to reduce energy demand. The methodology follows a quantitative comparative approach, using an energy simulation software to study two different types of BIPV technology (BISOL Premium BXO 365 Wp monocrystalline and BXU 330 Wp, polycrystalline) on an existing building by retrofitting a part of its curtain wall. This is to conclude the energy saving percentage and feasibility of both alternatives.Energies 2019, 12, 3946 2 of 15 in the building retrofit process and how it impacts the energy performance in existing buildings through the energy retrofit process. The study is conducted through computer simulation, using DesignBuilder software to compare the performance of two different types of building integrated photovoltaics (BIPV) technology (BISOL Premium BXO 365 Wp monocrystalline and BXU 330 Wp, polycrystalline) on an existing building by partial retrofit of its curtain wall. This is to conclude the amount of energy saved and feasibility of both alternatives. Literature ReviewRetrofitting refers to a modification process of completed and constructed buildings, this could be inclusive to the building systems or extend even more to include structure. The process is performed at a point following its initial construction and occupation as an aim for enhancing the building performance. Many aspects should be taken into consideration when retrofitting an existing building, which include: indoor air quality (IAQ), retrofit cost, construction burden, and retrofit aesthetics to the current occupants [4]. In many cases, retrofit targets the building energy performance enhancement which is often provided by an optimization process that is completely dependent on proper retrofitting strategies. The building envelope thermal characteristics are studied to enhance the building energy performance [5]. To retrofit a building envelope, interferences generally include fenestrations (windows, doors), roof, and walls. The vertical envelope, such as building facades, represents a huge area that can be utilized and integrated with photovoltai...
