Special Issue Information

Dear Colleagues,

At the December 2015 21st United Nations Climate Change Conference (COP21) in Paris, the Paris Agreement was adopted, which will go down in history as the first binding global climate agreement. The main objective of the Paris Agreement is to strengthen the global response to the threat of climate change. The signatory states commit themselves to the following:

Maintaining, in the long term, the global average below 2 ºC with respect to pre-industrial levels.
Limiting the increase to 1.5 ºC in order to reduce the impact and risks of climate change.
Global emissions must peak as soon as possible.
Implementation of rapid reductions once the above objectives have been achieved.

This Special Issue aims to present the main global advances in renewable energies and energy efficiency that will help in the fight against climate change. This Special Issue seeks contributions spanning a broad range of topics related, but not limited to:

Solar energy;
The use of rooftops for energy generation;
Energy conversion from urban biomass or residues;
Energy management for water;
Bioclimatic architecture and green buildings;
Wind energy cogeneration;
Next-generation renewable energy technologies;
Cogeneration;
Public and private energy saving;
Policies for urban energy saving;
Smart meters;
Zero-energy buildings;
Legislations, regulations, and standards of energy.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Enhancing the Energy Efficiency of Buildings by Shading with PV Panels in Semi-Arid Climate Zone

Abstract

Solar energy is one of the most abundant and available forms of renewable energy. Reliance on the electricity network can be decreased and net-zero energy achieved by mounting photovoltaic power on the tops of houses. Photovoltaic arrays can also change how the roof’s surface reacts to its environment. The influence of the structural system of a roof and weather on the energy consumption of a building is important. This research is concerned with focusing on the indirect effect of solar photovoltaic rooftop panels (shading effect) on the roof surface to see whether this effect is worth studying and calculating the total electrical load in the residential sector. Photovoltaic panels were modeled as a shading device, and the Integrated Environmental Solution-Virtual Environment Software was used to anticipate the monthly decline and growth in heating and cooling loads associated with the roof level. The influence of a photovoltaic system on a building’s roof-related energy load was measured concerning low-rise residential buildings in Mafraq city, which belongs to a mild dry-warm temperature zone. The findings indicated that a solar roof structure decreased heat loss by 4.85% in the summer and boosted heat transfer by 5.54% in the winter. The results highlight that renewable energy is very important in our times due to climate change and the increased demand for electricity by the residential sector, which is stimulated to find multiple ways to decrease and adapt to this change, and the aim of this paper helps to encourage to use solar energy by identifying the indirect effect of solar panels on building’s rooftops. This investigation also focuses on the value of offering essential instructions to who is concerned to the utilization of alternative energy to heat and cool structures, also will educate the public on a building’s total energy requirements, which is critical for future green structure design.

Reducing the Operating Energy of Buildings in Arid Climates through an Adaptive Approach

by Aiman Albatayneh, Mohammed N. Assaf, Renad Albadaineh, Adel Juaidi, Ramez Abdallah, Alberto Zabalo and Francisco Manzano-Agugliaro

Abstract

Due to its excessive energy consumption, the building sector contributes significantly to greenhouse gas (GHG) emissions. The type of thermal comfort models used to maintain the comfort of occupants has a direct influence on forecasting heating and cooling demands and plays a critical role in reducing actual energy usage in the buildings. In this research, a typical residential building was simulated to compare the heating and cooling loads in four different Jordanian climates when using an adaptive thermal model versus the constant setting of temperature limits for air-conditioning systems (19–24 °C). The air-conditioning system with constant temperature settings worked to sustain thermal comfort inside the building, resulting in a significantly increased cooling and heating load. By contrast, significant energy savings were achieved using the temperature limits of an adaptive thermal model. These energy savings equated to 1533, 6276, 3951, and 3353 kWh, which represented 29.3%, 80.5%, 48.5%, and 67.5% of the total energy used for heating and cooling for zones one, two, three, and four, respectively.
