Special Issue Information

Dear Colleagues,

The target of reducing energy consumption and greenhouse gas emissions implicates all of human life, including daily home routine and indoor thermal comfort. As disclosed in the IEA World Energy Outlook, in 2021, the final energy consumption of the building sector represented almost the 30% of the entire world demand. The largest amount of buildings energy need is related to space heating and cooling, which can be strongly influenced by several factors, e.g., environment, building structure and envelope, and HVAC management. Hence, in order to face the challenging energy targets of the 21st century, this Issue will promote the achievement of zero-emission buildings by 2028 for new buildings and 2050 for the existing ones. In order to meet this objective, scientists and designers are encouraged to adopt an effective and integrated approach to decrease end-use energy consumption and pollutant emissions in both designing new buildings and retrofitting existing ones.

Besides, the highly efficient building envelope and the high-performance and optimal management of the heating, ventilation and air conditioning (HVAC) systems are mandatory in order to achieve satisfactory results in tems of energy consumption reductions. The great potential of both increasing renewable energy source (RES) production and optimizing building envelope and plant systems should be considered.

This Special issue proposes to deal with the challenging topic of reaching zero-energy and zero-emission buildings and adopting high-efficiency building envelopes and HVAC plants integrated with RES.

Submissions to this Special Issue should focus on the different strategies to be adopted in the roadmap to the decarbonization of the building sector. Studies on integrated technologies and approaches for building and thermal plant aspects, RES productions, and energy storage and management are welcome. This includes the simulation and evaluation of building energy performance and development of cost-effective solutions. This Special Issue aims to collect the experiences of the researchers to enhance the diffusion of knowledge and improve energy efficiency in the built environment.   

We welcome manuscripts on the following topics, but not limited to these topics:

  • Zero-energy buildings;
  • Zero-emission buildings;
  • Net-zero-energy buildings;
  • Energy efficiency in the built environment;
  • Energy-efficient building systems;
  • Sustainable design;

The European Union aims to achieve climate neutrality by 2050, prioritizing energy efficiency particularly in the building sector. Despite significant policies, such as the EU Green Deal and Renovation Wave initiative, the rate of deep energy renovations remains insufficient, with only 0.2% annually versus the 3% required. Multiple barriers hinder the progress of deep energy renovations (DERs), including fragmentation among stakeholders, the limited coordination of RDI (Research, Development, and Innovation) efforts, and a lack of systemic approaches. The objective of this paper is to illustrate a holistic methodological approach for enhancing the DER market uptake based on transition pathways theory (TPT) and is designed to drive structural evolution in DER markets aimed at overcoming their main current constraints. To this end, five key transition pathways are outlined—namely institutionalization, clusterization, capitalization, digitalization, and exploitation—and are conceived for fostering coordination, integration, promotion, and efficient scaling of innovations along the whole DER value chain. This approach was tested in seven EU building market ecosystems under the H2020 re-MODULEES project, aimed at developing a market activation platform conceived as a digital enabler for next-generation One-Stop Shops (OSSs). This project yielded practical evidence on the potentiality of the TPT frame to strengthen and empower local ecosystems through stakeholders’ engagement and cooperation. The findings suggest that the TPT-based approach tested in re-MODULEES can effectively address structural challenges in diverse DER renovation markets, and for this reason, it may be also tested and extended in other ecosystems across Europe in order to be validated as a strategic approach at the EU level for facilitating the transition to low-carbon buildings.

In recent years, energy efficiency and the decarbonization of the building sector have become key goals in Europe. However, substantial efforts are still needed to support the increase in on-site energy generation from renewable energy sources (RES) and to phase-out the use of fossil fuels. Moreover, this challenge must be backed by financial mechanisms provided by Member States. In this context, the aim of this work is to investigate different RES generation layouts for a reference office building in Italy and to determine whether it can achieve the goal of a net zero energy building (net ZEB) or a positive energy building (PEB). Different layouts are analyzed from both energy and economic perspectives through dynamic energy simulation, considering different financial schemes, such as “net metering” (SSP) and “premium tariff” (RID). The results show that the energy performance improves due to the size and the characteristics of the PV system. However, the avoided operating costs due to RID increase linearly, while the economic benefits provided by the SSP scheme encourage an appropriate design of the renewable energy system, avoiding oversizing for economic profitability.
