“…The increase in CO 2eq emissions was primarily attributed to the increasing energy consumption under every control strategy, but also to the relatively low fluctuations of the electricity mix throughout the day, in terms of price and CO 2eq intensity. In other studies where cost or CO 2 MPC is applied, a reduction is observed both in energy consumption and in energy costs, and in carbon emissions; in fact, in the majority of cases the percentage reduction exceeds 10% compared to the reference scenario [16][17][18][19][20]22].…”

“…In every case, a reduction in dioxide emissions was observed. Other researchers studied the implementation of two different CO 2 MPCs to a large commercial building with two different HVAC settings and found decreases in emissions, especially in the case of exploiting renewable energy [19]. Vigna et al, 2021 [20], assessed building clusters with different thermal mass characteristics, which consisted of residential buildings with ideal heating systems, under CO 2 forcing factor smart control.…”

The EU energy and climate policy has set quantitative goals for decarbonization based on the energy efficiency and the evolution of energy systems. The utilization of demand side flexibility can help towards this direction and achieve the target of higher levels of penetration in regard to intermittent renewable energy production and carbon emission reduction. This paper presents a simulation-based assessment of thermal flexibility in a typical office building in Greece, which is a representative Mediterranean country. The use of variable speed heat pumps coupled with hydronic terminal units was evaluated. The research focused mainly on the evaluation of energy flexibility offered by energy stored in the form of thermal energy by utilizing the building’s thermal mass. The demand response potential under hourly CO2eq intensity and energy prices was investigated. The flexibility potential was evaluated under different demand response strategies, and the effect of demand response on energy consumption, operational costs, CO2eq emissions and thermal comfort was analyzed and discussed. The results showed that both control strategies based on both the CO2eqintensity signal and spot price signal have, in some cases, the potential for cost and emission savings, and in other cases, the potential to depreciate in terms of emissions and cost the increase of energy consumption due to load shifting.

“…In addition, common 3D-printed wall systems do not meet the energy requirements of cold climate zones. Esmaeilzadeh et al [95] investigated ways to create a zero-emission zone using a combination of control methods, including the application of control algorithms, environmental footprint considerations, solar energy utilization, and the modification of HVAC systems, retrofitting of HVAC systems, and the use of hybrid energy resources. EnergyPlus was used to validate the combination of control methods, apply optimized controllers to simulations, and compare the effects of different controllers on the efficiency of the building's hybrid HVAC system.…”

Buildings consume a significant amount of energy throughout their lifecycle; Thus, sustainable energy management is crucial for all buildings, and controlling energy consumption has become increasingly important for achieving sustainable construction. Digital twin (DT) technology, which lies at the core of Industry 4.0, has gained widespread adoption in various fields, including building energy analysis. With the ability to monitor, optimize, and predict building energy consumption in real time. DT technology has enabled sustainable building energy management and cost reduction. This paper provides a comprehensive review of the development and application of DT technology in building energy. Specifically, it discusses the background of building information modeling (BIM) and DT technology and their application in energy optimization in buildings. Additionally, this article reviews the application of DT technology in building energy management, indoor environmental monitoring, and building energy efficiency evaluation. It also examines the benefits and challenges of implementing DT technology in building energy analysis and highlights recent case studies. Furthermore, this review emphasizes emerging trends and opportunities for future research, including integrating machine learning techniques with DT technology. The use of DT technology in the energy sector is gaining momentum as efforts to optimize energy efficiency and reduce carbon emissions continue. The advancement of building energy analysis and machine learning technologies is expected to enhance prediction accuracy, optimize energy efficiency, and improve management processes. These advancements have become the focal point of current literature and have the potential to facilitate the transition to clean energy, ultimately achieving sustainable development goals.
