“…There are three input indicators for measuring LCEE (Chang et al, ; Wang, Zhao, Tsutsumi, & You, ), namely, x 1 total labour force (TLF), x 2 gross national expenditure (GNE), and x 3 total energy use (TEU), where TLF indicates the number of people (aged 15 years and above), TEU refers to the use of primary energy before transformation to other end‐use fuels. GDP is used as desirable output.…”

Despite great efforts being devoted to, and substantial resources being consumed by low-carbon economy (LCE) development globally, it appears that little is known about whether LCE development is efficient. This paper measures low-carbon economy efficiency (LCEE) performance from a global perspective. The Super-slack-based measure model is adopted to analyse the LCEE performance of 115 sample countries during 1999-2013. The Malmquist Productivity Index is used to evaluate the dynamic change of LCEE between sample countries. The results indicate that overall worldwide LCEE performance is at low levels, and the differences in LCEE performance among the 115 sample countries are significant. It also indicates that LCEE performance is generally better in developed countries. From the dynamic perspective, a significant improvement in LCEE performance was achieved globally during the survey period, with an overall annual increase of 0.75%. These results provide a valuable reference to policy-makers and practitioners for adopting measures to promote LCE development effectively at a global level.

“…Four carbon reduction strategies focus in building materials and processes in building fabrication were proposed and evaluated to contribute to climate change mitigation. As it was shown through the text, and analyzed by Wang [53], building technology plays an important role in determining building energy efficiency and consumption.…”

“…Another important aspect that concerns in building practitioners are that the cost and externalities, as pointed out Wang [53], they highlight that many firms are concerned that the climate change mitigation technologies and strategies may be associated with excessive costs and/or disruptions of business operations, and their burdens outweigh the operational and climate benefits. In this sense, Poveda and Young [55] argued that if it pays to be green, constructers firms can achieve win-win in both environmental and operational dimensions, because environmental pressures provide constructors firms with an opportunity to improve efficiency and competitiveness through environmental innovations in processes and products.…”

Abstract:The design and study of low carbon buildings is a major concern in a modern economy due to high carbon emissions produced by buildings and its effects on climate change. Studies have investigated (CFP) Carbon Footprint of buildings, but there remains a need for a strong analysis that measure and quantify the overall degree of GHG emissions reductions and its relationship with the effect on climate change mitigation. This study evaluates the potential of reducing greenhouse gas (GHG) emissions from the building sector by evaluating the (CFP) of four hotpots approaches defined in line with commonly carbon reduction strategies, also known as mitigation strategies. CFP framework is applied to compare the (CC) climate change impact of mitigation strategies. A multi-story timber residential construction in Quebec City (Canada) was chosen as a baseline scenario. This building has been designed with the idea of being a reference of sustainable development application in the building sector. In this scenario, the production of materials and construction (assembly, waste management and transportation) were evaluated. A CFP that covers eight actions divided in four low carbon strategies, including: low carbon materials, material minimization, reuse and recycle materials and adoption of local sources and use of biofuels were evaluated. The results of this study shows that the used of prefabricated technique in buildings is an alternative to reduce the CFP of buildings in the context of Quebec. The CC decreases per m 2 floor area in baseline scenario is up to 25% than current buildings. If the benefits of low carbon strategies are included, the timber structures can generate 38% lower CC than the original baseline scenario. The investigation recommends that CO 2 eq emissions reduction in the design and implementation of residential constructions as climate change mitigation is perfectly feasible by following different working strategies. It is concluded that if the four strategies were implemented in current buildings they would have environmental benefits by reducing its CFP. The reuse wood wastes into production of particleboard has the greatest environmental benefit due to temporary carbon storage.

“…The ESERS models can indicate various sophisticated issues, such as energy-saving and emission-reduction, economic growth, carbon emissions, carbon tax, energy intensity, energy efficiency and so on, in a regional energy system [14,20]. By analyzing the reciprocal causation of these factors, the improvements on energy efficiency, energy intensity and greenhouse gas emissions can be achieved to promote the energy structure transformation and transition to a low-carbon economy [12,13]. Most notably, Tian LX et al proposed a three-dimensional model of the ESERS in [17] considering the complicated relationship between energy-saving and emission-reduction, economic growth and carbon emissions.…”

“…Lots of work has been done to demonstrate the impacts of carbon emissions and economic growth on energy consumption [2,5,6,[12][13][14][15][16]. Besides, different mathematical models of energy-saving and emission-reduction system (ESERS) have been developed in [17][18][19][20] to simulate the nonlinear coupling dynamics of energy conservation, economic growth, carbon emissions, and renewable energy development in the evolutionary process.…”

A B S T R A C TThis paper proposes the fractional-order modeling for sliding mode control of a complex four-dimensional energy-saving and emission-reduction system (ESERS). In the proposed methodology, the fractional calculus techniques are employed to accurately model the dynamics of the ESERS, and the fractional-order model of the energy-saving and emission-reduction system (FOESERS) is formulated. With the proposed FOESERS, all of the equilibrium points and the corresponding eigenvalues are obtained, and the instability region and the state trajectories of FOESERS are also given. The FOESERS can represent complex dynamic behaviours with chaotic and unstable states on the energy conservation, carbon emissions, economic growth, and renewable energy development, and have a great impact on the formulation of government energy policies. Furthermore, based on the fractional Lyapunov stability and robust control theory, a sliding-mode controller is designed to control the FOESERS with model uncertainties and external disturbances to the equilibrium point in the finite time. Finally, simulation results confirm the effectiveness and robustness of the proposed scheme.
