Abstract [en]

Energy efficiency is a cornerstone of climate change mitigation. For buildings, facility management is an essential part of achieving efficient energy use while keeping tenants satisfied. This interview study explores success factors and barriers for facility management in maintaining energy efficiency over time in four approximately 10-year-old non-residential premises built as so-called nearly zero-energy buildings (nZEB) in Sweden. The study highlights the importance of functional digital tools, benchmarks, and building professionals’ involvement in ensuring energy efficiency. It also emphasizes the need for involvement communication and strategies to engage facility management in energy efficiency efforts. The study suggests that in-house and public policies can play a crucial role in sustaining high ambitions for energy efficiency. Access to professional support that is self-evident to use is identified as a critical success factor. Additionally, the research presents an analytic model that can be used in future studies to assess facility management organizations’ potential for maintaining energy performance in buildings over time.

Abstract [en]

The climate crisis demands an energy transition away from fossil fuels, and for the transport sector, this implies finding more electric or hydrogen-fuelled solutions. An emerging disruptive solution with high potential for improved sustainability is using drones as a mode of transport, i.e., Advanced Air Mobility for passenger and freight transport in urban and rural areas,fuelled by electricity or green hydrogen. As drones are being rapidly commercialized, there is a need for a policy framework for local and regional actors to address this in decision-making. This paper aims to develop a policy framework through a systematic literature review where findings have been validated by experts from industry and appropriate governance bodies. The results reveal three conceptual elements in the Advanced Air Mobility system where policy actions are needed: 1) primary technology, including vehicle-related aspects; 2) functionality, including infrastructure and operations; and 3) adoption, including the environment, market, and society. The overall lack of a multi-level governance model for Advanced Air Mobility and the scarcity of knowledge of the topic within vital fields such as energy systems and regional planning are also addressed. The findings are discussed in light of regulatory frameworks for drone transportation in Europe. The paper concludes with a policy development framework for regional Advanced Air Mobility deployment and provides policy implications.

Abstract [en]

About 12% of the EU's greenhouse gas emissions derive from construction of and energy use in buildings. To decrease energy use in buildings, more energy-efficient technologies must be implemented. However, there are barriers to the implementation of energy-efficient technologies. In this study, interviews were conducted with different stakeholders within a city district development project to find barriers towards the implementation of energy-efficient technologies in buildings. First, an investigation of barrier theory followed by three pre-interviews was conducted, which helped in forming questions for the interview study, which involved a total of 18 respondents. The respondents were from the client, facility manager, developer, consultants, project planners, contractor, and the local energy supplier. The barriers mentioned in the interviews were connected to different phases of a building project. There is a scarcity of studies where barriers in various phases of the construction process are explored. In conclusion, the most frequently mentioned barriers were connected to the Planning Program phase and the Project Planning phase. Two new barrier categories are suggested: Lack of Knowledge and Fear. The most prominent barriers to implementation of energy-efficient technologies were Inertia, Risk, Access to Capital and Lack of Knowledge. To increase the implementation of energy-efficient technologies in buildings, knowledge needs to be increased throughout the whole industry, and stakeholders need to step out of their comfort zone and not always do as they have done before. A key policy implication is the importance of capacity building in the early phases of the building process.

Abstract [en]

Nature-based solutions (NBS) are essential for carbon-neutral cities, yet how to effectively allocate them remains a question. Carbon neutrality requires city-led climate action plans that incorporate both indirect and direct contributions of NBS. Here we assessed the carbon emissions mitigation potential of NBS in European cities, focusing particularly on commonly overlooked indirect pathways, for example, human behavioural interventions and resource savings. Assuming maximum theoretical implementation, NBS in the residential, transport and industrial sectors could reduce urban carbon emissions by up to 25%. Spatially prioritizing different types of NBS in 54 major European Union cities could reduce anthropogenic carbon emissions by on average 17.4%. Coupling NBS with other existing measures in Representative Concentration Pathway scenarios could reduce total carbon emissions by 57.3% in 2030, with both indirect pathways and sequestration. Our results indicate that carbon neutrality will be near for some pioneering cities by 2030, while three can achieve it completely.

Abstract [en]

Electric drones as an autonomous mode of transport are scaling up to transform last-mile goods delivery, raising an urgent need for assessing impacts of drone transport from a systems perspective. In this paper, we conduct systems analyses to assess the environmental, economic, and delivery time impact of large drones for delivery scenarios to pick-up centers between mid-size cities predominantly in rural areas, and deliveries within city limits compared with electric and diesel trucks. Results show that large drones have lower emissions than diesel trucks for deliveries in rural areas and that drones don’t compete with electric trucks, mainly due to the high energy demand required for take-off and landing for each delivery. Furthermore, we show that electric drones are an economically more cost-effective option than road-bound transport modes such as diesel and electric trucks due to the high degree of automation, and also provide the fastest delivery times. Our analysis provides unique insights that drones can address rapid electrification and emergency applications due to low costs, high flexibility, and fast operations. However, for regulators and practitioners to realize it as an emission-friendly option it is necessary to determine the optimal size of drones, particularly for use cases in urban areas, avoid very low landings for deliveries, and have home deliveries instead of pick-up points.

Abstract [en]

In man-made energy systems like the electricity system, new concepts have the potential to influence and shape the development of the system. Sometimes the influence leads to a positive development and in other cases the new concept may lead into disadvantageous pathways. In this paper we argue that when a new concept is introduced, it may give rise to an unhinged paradox. An unhinged paradox implies that introducing a new concept, such as a new governance or management model, might lead to unintended consequences where some parts or the whole system become more unstable, or less resilient or unhinged. The transition of energy systems includes many “wicked” problems, i.e., aspects that are difficult to foresee the outcome of. The need for a rapid transition with an urgent need to implement new concepts together with a lack of or delayed feedback loops may give rise to wicked problems and unhinged systems. This unhinged paradox is likely to be found even beyond the scope of energy systems and will be further discussed in this paper in relation to the deregulation of the energy market, improved energy efficiency and energy flexibility.

Abstract [en]

In the EU, about 12% of the greenhouse gas emissions derive from buildings. To decrease the emissions from buildings, more energy-efficient technologies must be implemented. Drivers for the implementation of energy-efficient technologies are important to achieve this. Interviews were conducted with different actors within a city district development project to find drivers for the implementation of energy-efficient technologies in buildings. These drivers were connected to different phases of a building project to see when they have the highest potential impact. Connecting drivers to various phases of the construction process has not been explored before. In conclusion, drivers have the most impact during the Planning Program phase and the Project Planning phase. The most mentioned drivers are Cost reduction from lowered energy use, More knowledge within the building industry both stated by ten of 18 respondents, Long-term perspective at client, and National requirements and client demands both stated by eight of 18 respondents. The most prominent driver seems to be economic gains, and LCC calculations for showing potential economic gains are therefore a very important tool. Education with a subsequent certification on working with energy-efficient technologies and building techniques can be a driver and would also combat the lack of knowledge within the business. In-house knowledge at the client, Long-term perspective at the client, and Client demands are three great drivers. Clients in building projects should therefore aim to have good in-house knowledge, and a long-term perspective to be able to set the right requirements and drive for energy-efficient technologies.

Abstract [en]

Industrial energy efficiency is acknowledged as a cost-effective mean contributing to sustainable development and industrial competitiveness. Implementing energy management practices becomes even more imperative for developing countries, considering their energy usage trends and economic development forecasts. Based on the circumstances, an empirical investigation is conducted on energy efficiency and management practices, as well as barriers and drivers to energy efficiency in the energy-intensive industries of Bangladesh. The study finds that majority of the companies barely implement the energy management practices. Energy audits represent the mostly implemented energy management practice at the industries, though a comprehensive approach on a detailed level is still lacking. In addition, this study finds that the number of dedicated and specialised energy professionals employed in the industries is yet negligible. The cumulated results show that energy efficiency is mostly disrupted due to inadequate support from preeminent administration and bureaucratic intricacy. Energy blueprint cost-saving due to less use of energy and rules and regulations were distinctively signified as most imperative drivers for energy efficiency. On the other hand, lack of information is found to be the most significant barrier to consult energy service companies. Analysis of the country's energy usage and supply-demand relationship points towards insufficient energy efficiency measures and energy management practices in the country. The study also finds that energy efficiency could be improved by 8%–10% through the practice of energy management. Our findings, besides pointing out specific issues to be tackled in the specific context of investigation, pave the way for further research over industrial energy efficiency in developing countries.

Abstract [en]

The energy efficiency gap is known as the difference between optimal level of energy efficiency and the actual level of achieved energy efficiency. Energy management has proven to further close the energy efficiency gap. Energy management may differ depending on whether it concerns a large, energy-intensive company or small and medium-sized enterprises (SMEs). SMEs are of high interest since they form a large share of the economy today. For SMEs, a lighter form of energy management, in the form of energy efficiency network participation, has proven to deliver sound energy efficiency impact, while for larger, energy-intensive firms, a certified energy management system may be more suitable. However, various barriers inhibit adoption of energy efficiency measures. While there is an array of research on barriers to and driving forces for energy efficiency in general, research on barriers to, and driving forces for, energy management is rare, one exception being a study of energy-intensive pulp and paper mills. This holds even more so for industrial SMEs. This paper aims to identify the barriers to, and drivers for, energy management in manufacturing SMEs. Results of this explorative study show that the top four barriers to energy management are lack of time/other priorities, non-energy-related working tasks are prioritized higher, slim organization, and lack of internal expert competences, i.e., mainly organizational barriers. The top four drivers for energy management are to reduce production waste, participation in energy efficiency networks, cost reduction from lower energy use, and commitment from top management. Furthermore, results show that energy management among the studied SMEs seems to not be as mature, even though the companies participated in an energy management capacity building program in the form of energy efficiency networks, which, in turn, shows a still largely untapped potential in the societal aim to reduce the energy efficiency and management gaps. The main contribution of this paper is a first novel attempt to explore barriers to, and drivers for, energy management among SMEs.

Abstract [en]

Improved energy efficiency is one of the key elements to decouple energy-related emissions from economic growth. Since the energy management practices in small and medium-sized enterprises are underdeveloped, most of the energy efficiency potential is left untapped. Studies show that several barriers pertaining to economic, technological, and organizational systems lead to poor implementation rates of energy efficiency measures. An energy efficiency network is considered effective in overcoming these barriers and promoting energy management practices in small and medium-sized enterprises. This paper explores the role of energy efficiency networks, and specifically the role of its functions in overcoming the identified barriers from literature. This study was carried out as a multiple case study including 13 industrial small and medium-sized enterprises using semi-structured interviews with participants from companies in a Swedish regional energy efficiency network program. Results show that energy efficiency networks are effective in overcoming some of the barriers to energy efficiency implementation and that the present functions are effective in addressing some barriers faced by small and medium-sized enterprises, e.g., energy efficiency implementation barriers such as lack of time and resources. However, some barriers still remain as constraints for energy efficiency implementation, even after energy efficiency network participation.
