Towards Zero Energy Stadiums: The Case Study of the Dacia Arena in Udine, Italy

Abstract

The environmental impacts of sport events have been growing during the last decades, which has led to the organizing associations developing adequate countermeasures to both reduce carbon emissions due to construction and operational stages compensate for the emissions. This work aims at proposing an approach to stadiums energy enhancement that includes strategies largely recognized as effective and applicable to several building typologies (residential, commercial, academic, etc.). The selected case study is the Dacia Arena in northern Italy that has been recently refurbished and renovated. The proposed workflow has as a goal minimizing the increment of the operational emissions, caused by new heated areas in the stadium. Firstly, the energy consumption was estimated in dynamic state for Scenario 0 (current state) and Scenario 1 (refurbished state) to quantify the new plant’s energy demand. Secondly, two hypothetical system layouts were proposed and evaluated. In the first, the power for lighting, cooling and heating is supplied by a system that couples photovoltaic panels with heat pump. In the second, the same photovoltaic plant is integrated with a biomass plant and an absorption chiller. The comparison highlights the suitability of those interventions and the environmental advantages deriving from their exploitation.

Passenger Flow Pushing Assignment Method for an Urban Rail Network Based on Hierarchical Path and Line Decomposition

“…The results of classical Logit and C-Logit calculation are close to 0. It is too early to estimate the situation that p 2 ag is an effective path that no one chooses, which is inconsistent with the assumption of an effective path, so the results of the above two models are unacceptable. Relatively speaking, the results of Improved Logit and Improved C-Logit are more convincing.…”

“…As the backbone of the public transport system, urban rail transit has the characteristics of energy-saving, land-saving, large capacity, non-pollution and safety, which are suitable for the sustainable development of large and medium-sized cities [1][2][3][4]. With the expansion of the construction scale of urban rail transit networks in China, the demand for passenger flow has increased substantially.…”

Low Enthalpy Geothermal Systems in Structural Controlled Areas: A Sustainability Analysis of Geothermal Resource for Heating Plant (The Mondragone Case in Southern Appennines, Italy)

“…Low-temperature geothermal fields have been exploited over decades for industrial applications in Iceland, Hungary, China, Turkey, France, Germany, Russia, and other countries [2], and in recent times many authors propose the use of geothermal energy standalone or coupled with other renewable energy sources [3][4][5]. As an example, a classical low-temperature geothermal field of meteoric origin, in Kamchatka, Russia, has extracted thermal water since 1966 mainly in the mode of artesian flow to supply numerous swimming pools, district heating of two villages, greenhouse farming, and fish breeding [6].…”

Temperature Effects on Vibration-Based Damage Detection of a Reinforced Concrete Slab

“…Actual civil structures are susceptible to the influence of varying environmental factors and operational conditions such as humidity, wind and moving vehicles, however the most important factor has proven to be temperature [1][2][3]. In recent years, structural health monitoring under environmental variations has become a popular research topic in the field of civil engineering [4][5][6]. Moaveni and Behmanesh [7] investigated the effects of changing ambient temperatures on finite element (FE) model updating of the Dowling Hall Footbridge.…”
