- Publication 16 August 2021 Lightweight privacy-preserving data aggregation protocol against internal attacks in smart grid Privacy-preserving data aggregation has been studied extensively over the past decades, but there are still some concerns remained. For example, some schemes cannot resist against internal attacks, especially when the internal attack is launched by either the data centers that allocate the system security parameters or the attacker who shares the common information with the targeted user. In this paper, we propose a lightweight privacy-preserving data aggregation scheme, which is more efficient…
- Publication 16 August 2021 Engineering skills and knowledge related to nZEB construction The buildings sector is the largest energy-demanding and polluting sector in the global economy. The implementation of nearly Zero Energy Buildings contributes to reducing energy use and climate change. To support this construction there is a need for educating professionals with the required skills and competencies on energy-efficient buildings. This paper reports on the necessary knowledge to be acquired by engineers to deliver nZEB projects. Here, we identify the entire set of nZEB features…

- Publication 16 August 2021 Designing a sustainable business model for automated solar-PV drip irrigation for smallholders in Ghana Sustainable business model (SBM) research and practice has grown rapidly in the last two decades, not only showing the traits of an emerging research field, but also having an impact on business practices and government policies. Despite the wide-ranging academic and practical debates on SBMs, the academic literature still needs approaches specifically tailored to support the design of SBMs in developing countries, taking into account their characteristics, opportunities, and challenges. Our…
- Publication 16 August 2021 Accessibility, Infrastructure Provision and Residential Land Value: Modelling the Relation Using Geographic Weighted Regression in the City of Rajkot, India Amenities and infrastructure provision in urban areas are essential for the sustainable future of cities in developing countries like India. Indian cities have large development deficits and find it challenging to bridge the gap using traditional methods. Provision of these facilities costs money, which is often not available. However, access to amenities and infrastructure adds to land premium, which, if captured, can be used to finance the provision of these facilities. In India, very little…
- Publication 16 August 2021 Analyzing the energy system impacts of price-induced demand-side-flexibility with empirical data This paper assesses the potential effects on the energy system from a full roll out of a smart phone app designed to connect household electricity consumers with their consumption and price data. The effects of the app in allowing greater demand-side flexibility from household consumers is estimated based on data from an 18-month field trial involving 1557 Austrian households. These estimates are given as hourly price elasticities of electricity demand and hourly energy efficiency treatment…
- Publication 16 August 2021 Developing a common approach for classifying building stock energy models Buildings contribute 40% of global greenhouse gas emissions; therefore, strategies that can substantially reduce emissions from the building stock are key components of broader efforts to mitigate climate change and achieve sustainable development goals. Models that represent the energy use of the building stock at scale under various scenarios of technology deployment have become essential tools for the development and assessment of such strategies. Within the past decade, the capabilities of…
- Publication 16 August 2021 Environmental sustainability of data centres: A need for a multi-impact and life cycle approach This issue brief uses examples to showcase the substantial environmental impacts of data centres stemming from other life cycle stages than their operations and calls for the use of Life Cycle Assessment (LCA) to assess and address such impacts.
