Investigation of design strategies and quantification of energy flexibility in buildings: A case-study in southern Italy
2021
Abstract The need for nearly (net) zero energy buildings in the current European landscape does not merely refer to energy balances: the aim to investigate the interaction between generation and load and find sources of technical-economic energy efficiency is marking the rise in interest throughout research and practice of energy flexibility solutions in buildings. In this regard, the study aims at enhancing the energy flexibility of a building in southern Italy through Rule-Based Control algorithms for the control of the space heating system and the charge and discharge of an electricity storage. The influence of electricity pricing and the thermal comfort conditions on flexibility is also…
Environmental Sustainability Approaches and Positive Energy Districts: A Literature Review
2021
During the last decade, increasing attention has been paid to the emerging concept of Positive Energy Districts (PED) with the aim of pushing the transition to clean energy, but further research efforts are needed to identify design approaches optimized from the point of view of sustainable development. In this context, this literature review is placed, with a specific focus on environmental sustainability within innovative and eco-sustainable districts. The findings show that some sustainability aspects such as sustainable food, urban heat islands mitigation and co-impacts, e.g., green gentrification, are not adequately assessed, while fragmented thinking limits the potential of circularit…
A Set of Key Performance Indicators for Solar Heating and Cooling Systems
2017
The application of solar heating and cooling systems for building air-conditioning actually shows a significant potential of exploitation, particularly in sunny regions. The choice whether or not to apply such technologies in different climates should be based on the assessment of their energy/environmental, economic and social sustainability, as well as their technical characteristics as reliability, durability and energy efficiency. To support researchers and decision-makers in the selection of the best solar air-conditioning solution in a specific geographic and energy context, the paper proposes a set of technical, economic, energy/environmental and social key performance indicators. Th…
Structured methodology for selection of maintenance key performance indicators: Application to an oil refinery plant
2017
The novel contribution of the work is the proposal of a structured multi-step methodology that may support the Decision Maker (DM) in the measurement of maintenance performance by means of Maintenance Key Performance Indicators (MKPIs). To this aim, a multi-level hierarchical framework able to synthesize the most meaningful aspects affecting the maintenance results is designed. Then, MKPIs are selected from the literature, assigned to the hierarchical framework and ranked by an Analytic Hierarchy Process-based approach with incomplete comparison matrices. A mathematical model is finally formulated to select the optimal set of MKPIs. The methodology is implemented in an oil refinery plant an…
Unpacking Higher Educational Institutions (HEIs) performances through the institutional logics lens
2019
In the current knowledge-based economy, Higher Education Institutions (HEIs) are called to play different interconnected roles related to triple university missions. Alongside the two traditional missions of teaching and research, HEIs have experienced the emergence of the so-called “third mission”, which sees HEIs as knowledge-based agents part of ecosystems of public institutions, companies and citizens oriented to coknowledge creation. Finding a balance between the traditional missions and the third mission can be a serious challenge. For this reason, HEIs need to revise their objectives, strategies and performance indicator systems to plan, monitor and assess their social, cultural, and…
