Smart and Energy Efficient HVAC Systems Towards Building Decarbonizations

Dear Colleagues,

Heating, ventilation, and air conditioning (HVAC) systems are among the largest energy consumers in buildings and play a critical role in shaping both energy performance and indoor environmental quality. As the global community strives to mitigate climate change and decarbonize the built environment, smart and energy-efficient HVAC systems have emerged as key enablers of low-carbon, sustainable buildings.

This Special Issue provides a platform for interdisciplinary research from within both academia and industry, aiming to advance the next generation of HVAC systems that support building decarbonization while safeguarding occupant health, comfort, and well-being.

We welcome contributions that address new and existing buildings alike, including research on system retrofitting, modernization strategies, and the integration of advanced HVAC technologies in low- or net-zero-energy and/or airtight high-performance buildings. Simulation-based studies, digital tools, and performance modelling are also encouraged.

Topics of interest include but are not limited to the following:

• Smart, energy-efficient HVAC technologies and control strategies;
• Indoor air quality (IAQ) and indoor environmental quality (IEQ) in low-energy buildings;
• HVAC system retrofitting and modernization in existing buildings;
• HVAC design in new energy-efficient and net-zero buildings;
• PV and HVAC integration;
• Domestic hot water (DHW): Security of supply, energy efficiency, and the realization of design assumptions;
• Building energy and environmental performance simulation;
• AI, IoT, and machine learning applications in HVAC control and diagnostics;
• The integration of HVAC with renewable energy sources and energy storage;
• Predictive maintenance and fault detection;
• Occupant-centric HVAC control for comfort and energy balance;
• Lifecycle environmental and economic assessments for HVAC systems;
• Case studies demonstrating practical implementation and measured impacts;
• Designing new solutions, improving existing ones, and retrofitting.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies 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 2600 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.
