Geothermal energy could play a crucial role in the European energy market and future scenarios focused on sustainable development. Thanks to its constant supply of concentrated energy, it can support the transition towards a low-carbon economy. In the energy sector, the decision-making process should always be supported by a holistic science-based approach to allow a comprehensive environmental assessment of the technological system, such as the life cycle assessment (LCA) methodology. In the geothermal sector, the decision-making is particularly difficult due to the large variability of reported results on environmental performance across studies. This calls for harmonized guidelines on how to conduct LCAs of geothermal systems to enhance transparency and results comparability, by ensuring consistent methodological choices and providing indications for harmonized results reporting. This work identifies the main critical aspects of performing an LCA of geothermal systems and provides solutions and technical guidance to harmonize its application. The proposed methodological approach is based on experts’ knowledge from both the geothermal and LCA sectors. The recommendations cover all the life cycle phases of geothermal energy production (i.e., construction, operation, maintenance and end of life) as well as a selection of LCA key elements thus providing a thorough base for concerted LCA guidelines for the geothermal sector. The application of such harmonized LCA framework can ensure comparability among LCA results from different geothermal systems and other renewable energy technologies.

Low Carbon City

This paper, using literature analysis, explores the development of low-carbon pilot cities in China and its research progress, including the enrichment of the connotations of low carbon and low-carbon city, the progress in building China’s low-carbon cities, the relevant research by Chinese and foreign scholars and its trends. The result shows that for the construction of low-carbon cities in China, domestic and foreign scholars have conducted in-depth research on the connotations of low-carbon economy and low-carbon city, low-carbon index, carbon discharges peak value, technological approaches, energy utilization, low-carbon society, policy instruments and evaluating system, but the research is still subject to several limitations. For example, judging from the evaluation system of low-carbon cities, the research assigned small weights to the non-technical indexes such as low-carbon policies, governance mechanism and performance appraisal system. Judging from the spatial scale of case studies, the studies on the relatively developed cities in eastern China outnumber those on the cities in western China, especially in the minority areas. In terms of the factors influencing the construction of low-carbon cities, inadequate attention has been paid to the related psychological factors, in particular those of ethnic minorities.

Purpose The purpose of this paper is identification of a methodology to determine CO2 emissions through facility services on an approximate and sufficiently accurate basis. This methodology is to be used by German practitioners for request for proposals (RFPs) and offers of facility services. Design/methodology/approach In accordance with ISO 14067, a matrix of CO2-relevant modules for the representation of CO2 emissions from facility services is developed. Key figures for energy consumption, transport and equipment manufacture and use are used in a case study. Findings For a transparent CO2 assessment of facility services, the following modules are required: work clothing, devices, vehicles (service personnel), supplies, transportation of personnel and overhead (vehicles and office space). In the case study, facility services account for about 30 per cent of the CO2 emissions originating from the use of the building. Research limitations/implications The methodology developed is also applicable to other services. Prior to that, however, the investigation of additional facility services (catering or security) and an extension to other types of facilities is required (office building, hospital, etc.). Practical implications The developed methodology allows transparent competition for low-carbon services concepts, for example, in RFP procedures for facility services. Social implications CO2-optimised facility services increase the demand for low-emission operating equipment and resources. They therefore have an indirect influence on the development of a low-carbon economy. Originality/value To date, there has not been a methodology that supports a transparent and practical summary of the service-related CO2 emissions associated with the resources used in facility services.

Set Up

<p>Nowadays, utilizing shallow geothermal energy for heating and cooling buildings has received increased interest in the energy market. Among different technologies, large borehole heat exchanger (BHE) arrays are widely employed to supply heat to various types of buildings and districts. Recently, a 16-BHE array was constructed to extract shallow geothermal energy to provide heat to the newly-developed public building in Berlin. According to the previous geological survey, different non-homogeneous sedimentary layers exist in the subsurface, with variating groundwater permeabilities and thermal parameters. To estimate the performance of the BHE array system, and its sensitivity to different subsurface conditions, as well as to determine its thermal impact to the surrounding area, a comprehensive 3D numerical model has been set up according to the Berlin BHE array project. The model is simulated for 25 years with two finite element simulators, the open source code software OpenGeoSys (OGS) and the well-known commercial software FEFLOW. In the model, an annual thermal load curve is assigned to each BHE according to the real monthly heating demand. Although the way of the implementing parameters in the two programs differs from each other and some assumptions had to be made in the model comparison, the comparison result shows that both OpenGeoSys and FEFLOW produce in good agreement. Different parameters, e.g. the Darcy velocity, the thermal dispersivity of the aquifer, the surface temperature and the geothermal heat flux are investigated with respect to their impact on the underground and BHE circulation temperature. At last, the computed underground temperature and the brine fluid temperature evolution from OGS is benchmarked with the results from the model simulated in FEFLOW. The numerical experiments show that the the ground water field has the strongest influence on the brine fluid temperature within the BHEs. When the thermal dispersivity of the aquifer is considered, the mixing effect in the aquifer leads to a higher brine fluid temperature in the BHE, indicating a better thermal recharge of the system.</p>

To develop low-carbon tourism attraction is conducive to the transformation of tourism industry’s development mode. It can also help China to take the carbon-reducing responsibility in the world, reduce carbon emission and develop low-carbon economy and society. This paper takes Beijing Badachu Park as the case study to analyze the relationship between the development of low-carbon tourism attraction and the tourists’ low-carbon cognition. It shows that there’re two kinds of low-carbon cognition, one is “to know it” and the other is “to do it”. But the reality is there always has some inconformity between consciousness and behavior in low carbon tourism which is bad for the construction of tourism attractions. This article put forward some suggestions to solve this problem: “hardware” transformation, scientifically planning and management, to intervene tourists’ low carbon cognition through “attraction also community” ways, etc.
