Dear Colleagues,

Energy consumed by heating, ventilation and air conditioning systems (HVAC) in buildings represents an important part of the global energy consumed. Advanced building energy systems, efficient building energy saving technology, forward-looking building energy system planning and programs are all helpful in reducing building energy consumption. In addition, thermal energy storage (TES) is one of the most promising technologies to enhance the efficiency of renewable energy sources. TES overcomes any mismatch between energy generation and use in terms of time, temperature, power or site. Solar applications, including those in buildings, require thermal energy to be stored for periods ranging from very short durations (in minutes or hours) to seasonal storage. The advantages of using TES in an energy system are not only the increase in the overall efficiency and reliability, but it can also lead to better economic feasibility, reducing investment and running costs, less pollution of the environment and less CO₂ emissions.

This Special Issue aims to encourage researchers to publish in detail their work related to efficient energy utilization, and the design and application of thermal energy storage technology in buildings. Original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Modeling, experiments or analyses of building energy.
• Advanced building load forecasting methods.
• Energy planning and energy management of buildings or districts.
• Simulation of or experiments on advanced building energy systems and equipment.
• Integrated energy systems for buildings.
• New heat storage materials and phase change energy storage materials.
• Renewable energy utilization in the building area.
• Designs of new energy systems and thermal energy storage systems.

We look forward to receiving your contributions.

Manuscript Submission Information

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 2200 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.
