The present narrative review aimed to analyze the impact of the COVID-19 pandemic on the sustainable development goals (SDGS). This information would allow a better comprehension of the actual state of the SDGS and a more efficient programming in future interventions. To achieve the objective of the study, a consensual and critical review was carried out using both primary sources, such as scientific articles, and secondary sources, such as bibliographic indexes, web pages and databases. The Sustainable Development Goals are a global call to action to end poverty, close the gender gap, protect the planet, and improve the lives of people around the world. In 2015, the United Nations General Assembly adopted 17 goals as part of the 2030 Agenda for Sustainable Development, which sets out a plan to achieve the goals in 15 years. However, the COVID-19 pandemic crisis has been a turning point in the achievement of these goals, due to all its consequences at the political, economic, and socio-cultural levels. This review can be used as a guide for future research and reviews in order to understand the status of each of the SDGs and what actions have been taken and proposed in the aftermath of the pandemic in recent years.
This paper presents an energy performance assessment on an educational building in Barranquilla, Colombia. The electricity consumption performance was assessed using the software DesignBuilder for two different Air Conditioning (AC) systems. The current electricity intensity is 215.3 kWh/m2-year and centralized AC systems with individual fan coils and a water chiller share 66% of the total consumption and lighting at 16%. The simulation of the AC technology change to Variable Refrigerant Flow (VRF) resulted in an improvement of 38% in AC energy intensity with 88 kWh/m2-year and significant savings in electricity consumption and life-cycle cost of AC systems in buildings.
Abstract--In this paper a reflection on Cleaner Production as environmental management strategy and the advantages of it over the traditional approach of treatment at the end of the process. These advantages are mainly related to preventing pollution rather than treat it to avoid its effect preventive approach. Some results of the implementation of this strategy in Cuba are relate.Keywords--Cleaner production, pollution control, pollution prevention, environmental management, CubaResumen--En el trabajo se realiza una reflexión acerca de la Producción más Limpia como estrategia de gestión ambiental y las ventajas que de ella se obtiene con respecto al enfoque tradicional de tratamiento al final del proceso. Estas ventajas están relacionadas principalmente con su enfoque preventivo orientado a evitar la contaminación en lugar de tratarla para evitar su efecto. Se refieren algunos resultados de la aplicación de esta estrategia en Cuba.Palabras Clave--Contaminación, gestión ambiental, control de la contaminación, prevención de la contaminación, producción más limpia.
