“…Another study in Malaysia confirmed the potential to reduce energy consumption by applying energy-saving measures [12]. Other factors have a significant impact on energy usage patterns and characteristics, such as different types of buildings [13] resulting from the behavior of their occupants and weather conditions resulting from climate change [14]. These studies can provide insight into optimizing energy-saving measures for buildings.…”

Retrofitted Existing Residential Building Design in Energy and Economic Aspect According to Thailand Building Energy Code

Electrical energy usage in buildings is a challenging issue because many old buildings were not originally built to achieve energy efficiency. Thus, retrofitting old buildings to net-zero buildings can benefit both the owner and electric utilities. In this study, the BEC (building energy code) software was used to evaluate energy aspects of retrofitted buildings in compliance with Thailand’s building energy code to achieve a net-zero energy building. In addition, economic aspects were also studied to verify the feasibility for a project’s owner to invest in a retrofitted existing building. An existing residential building in Thailand was used as a case study. The results in terms of energy after retrofitting existing buildings into net-zero energy buildings show that the total energy consumption can be reduced by 49.36%. From an economic perspective, the investment cost for a retrofitted building can be compensated by energy saving in terms of discounted payback period (DPP) for approximately 4.36 years and has an IRR (internal rate of return) value of 19.23%. This result evidences the potential in both energy and economy for a project’s owner to invest in a retrofitted existing building in compliance with the building code, with potential for implementation with benefits on both electrical utilities and the project’s owner.

“…Such a methodology is an important issue for our future work. Last but not least, it is necessary to emphasize that, in order to manage the energy of IBs in an efficient manner, all of the solutions mentioned in the previous sections must consider other nontechnological aspects, which are very often forgotten, including the human dimension [243,244] as well as environmental challenges, such as climate change [245,246].…”

Intelligent Buildings in Smart Grids: A Survey on Security and Privacy Issues Related to Energy Management

et al. 2021

During the last decade, the smart grid (SG) concept has started to become a reality, mainly thanks to the technical progress achieved in telecommunications, informatics and power electronics, among other domains, leading to an evolution of the traditional electrical grid into an intelligent one. Nowadays, the SG can be seen as a system of smart systems that include cyber and physical parts from different technologies that interact with each other. In this context, intelligent buildings (IBs) constitute a paradigm in which such smart systems are able to guarantee the comfort of residents while ensuring an appropriate tradeoff of energy production and consumption by means of an energy management system (EMS). These interconnected EMSs remain the objective of potential cyber-attacks, which is a major concern. Therefore, this paper conducts a survey, from a multidisciplinary point of view, of some of the main security and privacy issues related to IBs as part of the SG, including an overview of EMS, smart meters, and the main communication networks employed to connect IBs to the overall SG. Future research directions towards a security enhancement from both technical and human perspectives are also provided.

“…Otros ven, de manera general, la influencia que tienen en el rendimiento energético de una edificación los efectos del cambio climático y a partir de ello, analizan los posibles mecanismos que pueden llevar a la adaptación o la mitigación de estos efectos (Barea, Victoria, Filippín, Monteoliva y Villalba, 2022;Yassaghi y Hoque, 2019). Existen trabajos que se concentran en establecer qué porcentaje de incertidumbre tienen los modelos que establecen las consecuencias del cambio climático sobre las edificaciones con relación al consumo de energía (Fonseca, Nevat y Peters, 2020), como también aquellos en los que se analiza, en torno al panorama mundial, cómo las condiciones climáticas del exterior de la edificación influyen en los cambios que se producen en temas del confort interior (Congedo, Baglivo, Seyhan y Marchetti, 2021). Distintos esfuerzos se han enfocado exclusivamente en el consumo de energía: Joarder Price y Mourshed (2009), entre otros, advierten que, por cuenta del aumento de temperatura que se ha proyectado, las edificaciones ya construidas corren el riesgo de ser inhabitables en el futuro, en caso de que no usen sistemas de refrigeración adicionales.…”

The bioclimatic performance of buildings under climate change scenarios has been extensively studied from a thermo-energy perspective but hardly studied at all from the perspective of indoor daylight sufficiency. This shortcoming is related to the invariability of radiation data in the available weather files of future scenarios. This research proposes identifying the impacts that the variability of radiation data in weather files of future scenarios would have on daylight sufficiency in indoor spaces. The methodology includes the adaptation of available weather files and the running of daylight simulations for hypothetical workspaces located in Medellín, Colombia. The results show differences in the Spatial Daylight Autonomy – SDA metric of up to 18% in different future scenarios. In conclusion, the need is outlined to refine predictions of outdoor daylight availability that allow improving daylight performance evaluations under climate change scenarios.
