Assessing energy, economic, environmental and social impacts of fostering energ...
Tenente, Marcos; Henriques, Carla; Gomes, Álvaro; Silva, Patrícia Pereira daThis work suggests an overarching methodology that couples Hybrid Input–Output Lifecycle Analysis with thermal dynamic simulation. This methodological framework allows for a comprehensive evaluation of the energy, economic, environmental, and social impacts of fostering energy efciency solutions in the residential sector. The main goal is to provide practical guidance to decision-makers in the formulation of ap...
Electricity, Transportation, and Water Provision of 100% Renewable Energy for R...
Torabi, Roham; Gomes, Álvaro; Morgado-Dias, FernandoThe integration of variable renewable energy sources in islands has become crucial in reducing their dependency on imported fossil fuels. This study aimed to assess the energy transition of an island towards a 100% renewable energy system for power generation, inland transport, and potable water provision. Linking various fossil-fuel-consuming sectors, such as transport and potable water supply systems, may str...
How organizational constraints undermine sustainability actions in a university...
Amaral, Ana Rita; Rodrigues, Eugénio; Gaspar, Adélio Rodrigues; Gomes, ÁlvaroHigher Education Institutions frequently struggle between the urgency to advance toward more sustainable campuses and the slow pace of their transformation. Although several stimuli and barriers are identified in the scientific literature, difficulties persist as several actions commonly assumed as best practices demonstrate to fall short of planned goals. Findings in the literature are generic, lacking the ide...
An Economic Assessment of the Contributions of 5G into the Railways and Energy ...
Corujo, Daniel; Quevedo, José; Aguiar, Rui L.; Paixão, Paulo; Martins, Hugo; Gomes, ÁlvaroThis paper presents an economical assessment of the benefits of introducing 5G technologies into pilot use cases pertaining to the railroad transportation and energy sectors. For each of the pilots, undergone by EFACEC Engenharia e Sistemas and EFACEC Energia, respectively, under the scope of the H2020 5Growth project, the expenditure and benefits expected from introducing 5G capabilities over their on-going op...
Multiple Impacts of Energy Efficiency Technologies in Portugal
Tenente, Marcos; Henriques, Carla; Gomes, Álvaro; Silva, Patrícia Pereira da; Trigo, AntónioPortuguese programs aimed at fostering Energy Efficiency (EE) measures often rely on cost–benefit approaches only considering the use phase and neglecting other potential impacts generated. Therefore, this work suggests a novel methodological framework by combining Hybrid Input–Output Lifecycle Analysis (HIO-LCA) with the Portuguese seasonal method for computing the households’ energy needs. A holistic assessme...
Lessons from unsuccessful energy and buildings sustainability actions in univer...
Amaral, Ana Rita; Rodrigues, Eugénio; Gaspar, Adélio Rodrigues; Gomes, ÁlvaroHigher Education Institutions (HEIs) are increasingly striving to deploy actions that promote the efficient use of energy and other resources on university campuses. Successful sustainability initiatives are vastly described in literature, especially for the operations phase. In turn, reports on unsuccessful cases are small in number, or are overlooked and undiscussed, possibly providing a biased view of realit...
Energy Transition on Islands with the Presence of Electric Vehicles: A Case Stu...
Torabi, Roham; Gomes, Álvaro; Morgado-Dias, F.Facilitating high-RES (Renewable Energy Resources) penetration via integrated resource management is considered a promising strategy on different islands worldwide. For this work, the Portuguese island of Porto Santo is established as a test bench using actual data from the island. Given its geographical condition and energy needs, integrating the management of different resources (namely, the electric power gr...
The contribution of ventilation on the energy performance of small residential ...
Fernandes, Marco S.; Rodrigues, Eugénio; Gaspar, Adélio Rodrigues; Costa, José Joaquim; Gomes, ÁlvaroEfficient ventilation is an effective method for reducing thermal loads inside buildings, thus decreasing cooling energy consumption. This is especially relevant in warmer climates. Therefore, it is important to better understand the role that different ventilation parameters play on air-conditioning consumptions. This study analyzes the effect of three different ventilation parameters – air flow rate, minimum ...
A review of empirical data of sustainability initiatives in university campus o...
Amaral, Ana Rita; Rodrigues, Eugénio; Gaspar, Adélio Rodrigues; Gomes, ÁlvaroGiven the need to actively address the challenges of climate change, university leaders have a growing interest in reducing their campuses’ environmental impact. This article carries out a comprehensive literature review on the implemented actions and initiatives in university campuses reported in scientific publications. In addition, case studies carried out in universities are also reviewed, giving particular...
The impact of thermal transmittance variation on building design in the Mediter...
Fernandes, Marco; Rodrigues, Eugénio; Gaspar, Adélio; Costa, José; Gomes, ÁlvaroContrarily to what happens in northern European countries, buildings in the Mediterranean region are prone to overheating. Consequently, it is important to better understand the role that the thermal transmittance of the building envelope elements has on air-conditioning consumptions. This paper analyzes the effect of different U-values on building design in the Mediterranean area. 192 000 residential buildings...
