Initial Measure

Rapidly increasing global energy demand has raised concerns about the exhaustion of energy resources and the consequent heavy environmental impact. Improving energy efficiency in cities comprises an initial measure for addressing these phenomena. Within the current context of globalization, EU initiatives and policy targets have been proposed in order to revise urban development strategies and motivate its member states (MSes) toward “zero-energy objectives”. Providing a methodological approach with a simulation district analysis, the present article summarizes how this challenge was analyzed in an existing district in Belgium. This study contributes to the scientific discussion by analyzing the applicability of a holistic approach to zero-energy objectives on a larger scale.

AbstractSustainable development of container terminals is based on energy efficiency and reduction in CO2 emissions. This study estimated the energy consumption and CO2 emissions in container terminals according to their layouts. Energy consumption was calculated based on utility data as well as fuel and electricity consumptions for each container-handling equipment in the container terminal. CO2 emissions were estimated using movement modality based on the number of movements of and distance travelled by each container-handling equipment. A case study involving two types of container terminal layouts i.e. parallel and perpendicular layouts, was conducted. The contributions of each container-handling equipment to the energy consumption and CO2 emissions were estimated and evaluated using statistical analysis. The results of the case study indicated that on the CO2 emissions in parallel and perpendicular layouts were relatively similar (within the range of 16–19 kg/TEUs). These results indicate that both parallel and perpendicular layouts are suitable for future ports based on sustainable development. The results can also be used for future planning of operating patterns and layout selection in container terminals.

Climate responsive design can amplify the positive environmental effects necessary for human habitation and constructively engage and reduce the energy use of existing buildings. This paper aims to assess the role of the thermal adaptation design strategy on thermal comfort perception, occupant behavior, and building energy use in twelve high-performance Belgian households. Thermal adaptation involves thermal zoning and behavioral adaptation to achieve thermal comfort and reduce energy use in homes. Based on quantitative and qualitative fieldwork and in-depth interviews conducted in Brussels, the paper provides insights on the impact of using mechanical systems in twelve newly renovated nearly- and net-zero energy households. The article calls for embracing thermal adaptation as a crucial design principle in future energy efficiency standards and codes. Results confirm the rebound effect in nearly zero energy buildings and the limitation of the current building energy efficiency standards. The paper offers a fresh perspective to the field of building energy efficiency that will appeal to researchers and architects, as well as policymakers.

Infrastructure Project

Purpose This study aims to provide an example of how higher education institutions (HEIs) can use a successful campus infrastructure project to fund a student- and faculty-led, community-success platform that advances the sustainable development goals (SDGs). Design/methodology/approach The authors applied conceptual models for systems thinking and creating virtuous cycles to analyze Millersville University’s work to establish a community-impact, micro-grant fund using cost savings and utility rebates associated with a new campus zero-energy building. The analysis provides a case study that other HEIs can implement to create university and community virtuous cycles that advance the SDGs. Findings The case study suggests that as HEIs face increasing financial challenges, opportunities exist to capitalize on philanthropic giving and other funding sources to support community prosperity and increase university vitality through a shared responsibility paradigm centered on the SDGs. Practical implications This case study identifies specific funding sources that HEIs can use to fund campus and community sustainability projects using the SDG framework, mechanisms for establishing shared purpose around that impact and a conceptual model for thinking about opportunities to leverage philanthropic giving to create a virtuous cycle that increases university vitality through community impact. Social implications Constructing a campus zero energy building funded in part through philanthropic giving provided a unique opportunity to explore how a project’s success can be leveraged to create additional community successes. This case study offers an example for how to convert one success into a platform that funds projects that have direct community impact in one or more of the SDG goal areas. Originality/value This paper aims at bridging the gap between theoretical frameworks for community sustainable development and descriptive-only case studies by using a case study to demonstrate a conceptual model or framework for advancing community sustainability (Karatzoglou, 2013). The case study provides a unique model for using utility rebates associated with an infrastructure project that was funded through philanthropic giving to establish a fund for projects that support the community. Utility rebates associated with campus energy efficiency projects are often otherwise overlooked, used to fund additional energy efficiency projects or simply returned to a university’s operating budget. For some HEIs, this model may connect the work of facilities staff to student success in ways that have not previously been explored. For others, this alternative use of utility rebates may offer an opportunity to increase the investment value of utility rebate dollars by creating virtuous cycles within their communities that contribute to university vitality.

Numerous evaluation metrics and standards are being proposed across industry and government to measure and monitor the energy efficiency of data centers. However, the energy use of data centers is just one aspect of the environmental impact. In this paper, we explore the overall environmental footprint of data centers beyond just energy efficiency. Building upon established procedures from the environmental sciences, we create an end-to-end life-cycle model of the environmental footprint of data centers across a diverse range of impacts. We test this model in the case study of a hypothetical 2.2-MW data center. Our analysis suggests the need for evaluation metrics that go beyond just operational energy use in order to achieve sustainable data centers.

Step Method

This paper describes a four-step method to analyze the utility bills and weather data from multiple residences to target buildings for specific energy conservation retrofits. The method is also useful for focusing energy assessments on the most promising opportunities. The first step of the method is to create a three-parameter changepoint regression model of energy use versus weather for each building and fuel type. The three model parameters represent weather independent energy use, the building heating or cooling coefficient and the building balance-point temperature. The second step is to drive the models using typical TMY2 weather data to determine Normalized Annual Consumption (NAC) for each fuel type. The third step is to create a sliding NAC with each set of 12 sequential months of utility data. The final step is to benchmark the NACs and coefficients of multiple buildings to identify average, best and worst energy performers, and how the performance of each building has changed over time. The method identifies billing errors, normalizes energy use for changing weather, prioritizes sites for specific energy-efficiency retrofits and tracks weather-normalized changes in energy use. The principle differences between this method and previously defined ones are that this method seeks to use inverse modeling proactively to identify energy saving opportunities rather than retroactively to measure energy savings, it tracks changes in building performance using sliding analysis, and it uses comparisons between multiple buildings to extract additional information. This paper describes the method, then demonstrates the method through a case study of about 300 low-income residences. After applying the method, targeted buildings were visited to determine the accuracy of the method at identifying energy efficiency opportunities. The case study shows that over 80% of the targeted buildings presented at least one of the expected problems from each type of retrofit.

Zero Energy Buildings

For a good approach to new challenges recommended by EU Energy Performance of Buildings Directive, nearly Zero Energy Buildings (nZEB) concept for new residential buildings is conceived in order to drastically improving the overall performance of classical buildings, especially in terms of energy use, production and CO2 equivalent (CO2e) emissions. This paper shows the results of the case study where was investigated energy, economic and environmental performances of hybrid solar and wind system for neutral in terms of climate parameters nZEB. The aim of this study was to demonstrate the capability and feasibility of RES hybrid technology for the energy supply of Romanian nZEB, and also, was to establish new general criteria with the goal to determinate the optimal design solution and providing general principles for green energy production. The main results reveal that Romania has a potential for green energy to implement the new concept nZEB and the global technical optimum of a hybrid system for nZEB is determined by the optimal interaction between the design parameters. The hybrid solar and wind electric systems are functioned in operational stand alone mode, its are supplied 100% by energy from RES and embedded CO2 emissions are decreased by over 50% compared to the classics systems.
