“…In the three indicators, the same three families of materials control over 60% of these indicators, except for EE, for which the family of bitumen and asphalt is also important. The results obtained are similar to those in the previous research, where ten urbanization materials, in industrial and residential projects, control 91% of the total impact in terms of the ecological footprint, with the greatest impact provoked by asphalt and concrete [29].…”

“…In a second level, data from construction cost databases and environmental product information such as eco-labels and/or generic LCA databases are combined. In the third level, assessments are applied to the elements in the project budget, thereby obtaining the incorporated WF, CF, and EE, which together provide an "environmental budget" [29]. These three environmental impacts have also been assessed in urbanization projects [30], and by employing Building Information Modelling [31].…”

“…The environmental impact of materials includes the energy and water consumed in the provision of the building materials, from the cradle to the door of the factory and their transport to the construction site, whose approximated distance covered by transport is in Andalusia, Spain, is defined [29]. For the transportation of concrete, the truck capacity considered is 24,000 kg, and the distance travelled is 20 km.…”

Urbanization projects, understood as those supplying basic services for cities, such as drinking water, sewers, communication services, power, and lighting, are normally short-term extremely scattered actions, and it can be difficult to track their environmental impact. The present article’s main contribution is to employ the project budgets of public urbanization work to provide an instrument for environmental improvement, thereby helping public procurement, including sustainability criteria. Two urban projects in Seville, Spain are studied: the first substitutes existing services, and the second also includes gardens and playgrounds in the street margins. The methodology finds the construction elements that must be controlled in each project from the perspective of three indicators: carbon, water footprints, and embodied energy. The main impacts found are due to only four construction units: concrete, aggregates, asphalt, and ceramic pipes for the sewer system, that represent 70% or more of the total impact in all indicators studied. The public developer can focus procurement on those few elements in order to exert a lower impact and to significantly reduce the environmental burden of urbanization projects.

“…This encourages architects and engineers to design more sustainable buildings, which implies lower energy and resource consumption [1]. Several tools and calculation models to determine the environmental impact of the construction sector are in place, whether using single issue indicators, such as the embodied energy (EE) or carbon footprint (CF) [2], or more complex ones such as emergy [3,4], the ecological footprint (EF) [5][6][7][8][9], CML, or the eco-indicator, also known as multivariable indicators.…”

The construction sector is one of the most polluting industries, generating between 30% and 40% of the worldwide environmental burden in terms of raw materials, direct and indirect energy consumption, waste, and CO2 emissions. Recent advances in computer science and data management have facilitated the evaluation of present and future impacts, thus improving the sustainability of architectural designs. Powerful software tools, such as Building Information Modelling (BIM), allow environmental indicators to be incorporated into the construction elements that make up the project to evaluate it during the design stage. In this work, the state of the art of ecological indicator application through BIM platforms is studied. Barriers and uncertainties are also identified. Subsequently, a model is proposed to evaluate the environmental impact of an urbanization process or a project through several ecological indicators (carbon footprint, water footprint, and embodied energy). To perform this analysis, the most important aspect is to determine the quantities of each construction element and their clear decomposition into subelements, since both aspects add certainty to the analysis. For this purpose, construction cost databases are a good instrument for introducing environmental awareness. The reliability of LCA data, which can be obtained from generic databases or ecolabels such as environmental product declarations, becomes crucial.

“…Cerutti et al used a fruit production system as an example and quantified the environmental impacts associated with four different units based on the EF method [38]. Mikulčić et al used the EF method to measure energy consumption and CO 2 emissions from different cement production processes [39]. Guerrero et al, selecting the urbanization and housing construction in Andalusia as an example, calculated the ecological footprint of the construction projects in the stages of urbanization, construction, decoration, or demolition, and then used the general language in the industry to control the environmental impact [40].…”

China’s achievements in climate change and clean energy have been recognized by the international community. Although China has achieved successes in the field of clean energy, especially clean power dispatch, power dispatch is still one-sided and incomplete when considering environmental aspects. This paper presents a comprehensive production cleanliness evaluation model to assign a comprehensive environmental value as a reference for clean power dispatch. The model considers all the pollutants currently regulated in China’s coal-fired power plants, carbon emissions, and sustainability as three basic environmental constraints. Then, emergy analysis is used to unify the input/output materials with different units of measurement, and the emergy-based environmental value added (EEVA) value is constructed. As an integrated environmental value, the EEVA can provide an environmental reference for clean power dispatch. Finally, we selected a representative coal-fired power plant in China as a case study. By applying the above model, the dispatching sequence for four generating units was arranged from the perspective of cleanliness.
