Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit papers to the journal Energies for a Special Issue that will be entirely devoted to “Energy conservation and carbon mitigation technology of buildings”. The Special Issue will expand on essential technical challenges for building energy conservation and carbon mitigation. This Special Issue continues to be the best opportunity you will have to exchange information, formulate strategic ideas, and solve problems to manage and optimize your unconventional resource plays.

Energy conservation and carbon mitigation of buildings are essential for realizing carbon neutrality. There are many innovations in building energy conservation technology and decarbonization technology, including the application of renewable energy in buildings, carbon capture, utilization, and storage (CCUS), building electrification, intelligent control, etc. Therefore, the progress in technology improvement and the positive effects of government policy for buildings to transition into being carbon-neutral are worthy of investigation. It can promote the development of zero-carbon buildings and assist the government in developing more accurate and feasible strategies for building decarbonization.

Under this research topic, we call for papers that focus on the technology and method for achieving building decarbonization from a theoretical and practical perspective. The studies in carbon mitigation management and policy for the building sector worldwide are welcome. The research topic is intended as a state-of-the-art resource for researchers, practitioners, and decision-makers interested in assessing the pathways to carbon neutrality in low-carbon buildings and communities. Topics of interest for the Special Issue include, but are not limited to, the following:

Application of renewable energy in buildings.
CCUS technology for building decarbonization.
Energy conservation technology for buildings.
Low-carbon buildings and communities.
Pathways for building decarbonization.
Energy flexibility of buildings.
Demand response management and control.
Integrated energy networks and microgrids.

Abstract

The district heating area in China is continuously increasing, which brings an increase in district heating load. In order to solve the shortage of heating power and realize the carbon neutral target, this study proposes two retrofit schemes for district heating system by integrating air source heat pump and water source heat pump, respectively. Mathematical models are established to study the performance of the integrated systems and a bilevel optimization model is proposed to optimize them. The results show that the air source heat pump combined district heating system has better performance compared to the conventional system, which reduces 50% energy consumption, 10.8% carbon emissions and achieves better economy. The dynamic coupling property of the district heating network and power grid are also considered, and the results indicate that the introduction of air source heat pump can effectively improve the efficiency and stability of power grid and reduce the seasonal fluctuation. The potential of large-scale application of air source heat pump combined system in Beijing is evaluated. The results reveal that retrofit scheme of integrating air source heat pumps into district heating system can cover 2930 MW heating load and bring 362 million Chinese Yuan profit by reducing 219,000 tons of carbon emissions and 539,000 tons of standard coal consumption in 2025.

Abstract

In order to address global warming, most countries in the world have established carbon neutral targets and are continuously taking action to achieve carbon neutrality. The building sector accounts for 36% of end-use energy consumption and 37% of energy-related CO₂ emissions globally, so carbon mitigation in building sector is considered to be the most critical step in completing the “last mile” of global carbon neutrality. Low-carbon buildings and communities are the foundation for achieving low-carbon cities and the key transition to reach the goal of carbon neutrality. Therefore, this review aimed to: (a) provide a comprehensive review of countries’ policies on low-carbon buildings and communities and a theoretical basis for improving the corresponding laws and regulations; (b) investigate low-carbon technologies related to building and community construction and operation, as well as identify the current technology gaps; (c) provide a comprehensive overview of low-carbon buildings and communities assessment systems to analyze and evaluate the economic, technical, environmental and social benefits of current building and community energy systems; and (d) identify enablers and barriers in low-carbon buildings and communities to provide direction for future research. The results of this paper can provide comprehensive insights in to further achieving low-carbon buildings and communities. Full article
