Special Issue Information

Dear Colleagues,

Energy efficiency is one of the key strategies with which to reduce greenhouse gas emissions and mitigate climate change. Buildings and transportation are two of the largest energy-consuming sectors in the world, accounting for about 40% and 30% of global final energy consumption, respectively. Improving energy efficiency in buildings and transportation can not only save energy and costs, but also enhance comfort, convenience, health, safety, and environmental quality.

This Special Issue aims to collect original research articles and review papers on the latest developments and challenges in energy efficiency in buildings and transportation. We invite contributions that address topics such as the following:

Energy-efficient design, construction, operation, and retrofitting of buildings;
Energy-efficient technologies and systems for heating, cooling, ventilation, lighting, and appliances in buildings;
Energy-efficient materials and components for building envelopes and structures;
Energy management and optimization in buildings and districts;
Smart building and smart grid integration;
Energy performance assessment and certification of buildings;
Energy-efficient modes and systems of transportation, such as electric vehicles, hybrid vehicles, public transport, cycling, walking, etc.;
Energy-efficient technologies and systems for propulsion, traction, braking, and auxiliary services in transportation;
Energy management and optimization in transportation networks and fleets;
Smart transportation and smart grid integration;
Energy performance assessment and certification of transportation modes as well as systems;
Policies, regulations, standards, incentives, and barriers for energy efficiency in buildings as well as transportation;
Socioeconomic and environmental impacts of energy efficiency in buildings as well as transportation.

We welcome both theoretical and empirical studies that provide novel insights into energy efficiency in buildings as well as transportation. We also encourage interdisciplinary and cross-sectoral studies that address the interactions and synergies between buildings and transportation in terms of energy efficiency.

Abstract

The increasing reliance on electric vehicle (EV) charging in buildings requires balancing the load from other building systems to support the new demand. This paper uses a study case in a Near-Zero Energy Building (NZEB) educational facility located in the Brazilian Amazon to verify how much the energy efficiency (EE) measures would improve the existing ratings of the building and supply the expansion of EV demand. A comprehensive building energy load and energy performance analysis were conducted in four steps, following the mandatory Brazilian requirements for EE in public buildings, using measured data, computer modeling, and thermoenergetic analyses using OpenStudio version 1.1.0 and EnergyPlus software version 9.4.0. First, the EE retrofit measures were proposed and evaluated, targeting the air conditioning and lighting systems. Subsequently, an equation was elaborated to indicate the maximum level of energy consumption that could be increased without compromising the building’s energy performance and NZEB classification. Finally, Open DSS software version 10.0.0.2 was used to simulate the increased availability of EV charging after the retrofit. With the proposed retrofit, the building improved the EE ratings by three levels, and the percentage of the NZEB rating increased by 33.28%. These measures also increased the EV charging load by 20%, maintaining the maximum EE level and the NZEB classification, although EV maximization reduced self-sufficiency by 9.78% compared to the retrofit-only scenario.

Abstract

The growth of electric vehicles (EVs) and their integration into existing and future buildings bring new considerations for energy efficiency (EE) and balance when combined with renewable energy. However, for buildings with an energy efficiency label, such as Near Zero Energy Building (NZEB) or Positive Energy Building (PEB), the introduction of EVs may result in the declassification of the EE label due to the additional energy required for the charging infrastructure. This underscores the increasing relevance of demand-side management techniques to effectively manage and utilize energy consumption and generation in buildings. This paper evaluates the influence of electric vehicle (EV) charging on NZEB/PEB-labeled buildings of the Brazilian Building Labeling Program (PBE Edifica). Utilizing on-site surveys, computational modeling, and thermos-energetic analysis with software tools such as OpenStudio v. 1.1.0 and EnergyPlus v. 9.4.0, an energy classification was conducted in a building in the city of Belem, State of Para, Brazil. Subsequently, power flow simulations employing probabilistic models and Monte Carlo approaches were executed in the OpenDSS software v. 10.0.0.2 to examine the impact of EV integration, both with and without the implementation of demand-side management techniques. Analyses using the labeling methodology demonstrated that the building has EE level C and NZEB self-sufficiency classification. The assessment of the impact of EV integration on the building’s total energy consumption in the base (current) scenario was carried out in two scenarios, with (2) and without (1) supply management. Scenario 01 generated a 69.28% increase in energy consumption, reducing the EE level to D and resulting in the loss of the NZEB class. Scenario 02 resulted in a smaller increase in energy consumption of 40.50%, and guaranteed the return of the NZEB class lost in scenario 1, but it was not enough to return the EE level to class C. The results highlight the need for immediate and comprehensive energy management strategies, as the findings show that the two scenarios present a difference of 41.55% in energy consumption. Nonetheless, these strategies are not enough if other consumption restrictions or energy efficiency measures are not applied to other building systems. Full article
