El siguiente documento presenta un proceso sistemático del uso de la energía a través de un análisis de indicadores energéticos en un edificio sanitario, donde se afirma la importancia de requerimientos de perfiles de consumo energético con regularidad, siendo consciente de esto, este trabajo estudia el desempeño energético y establece indicadores de rendimiento energético específico de algunas áreas sanitarias. Los autores analizaron un hospital básico situado en la provincia de Cotopaxi (Ecuador), dotado de 15 camas, donde se realizó un balance energético, determinando a la energía eléctrica como el mayor portador energético con un 46,84% , la tarifa eléctrica se evaluó durante el periodo de un año (2022), identificando un consumo anual de 124 030 kWh, se identificó el porcentaje distribuido de energía eléctrica en este hospital, siendo el de mayor consumo los motores eléctricos con un 38%, e iluminación con un 22%, e identificó indicadores energéticos que permitieron tomar decisiones que ayuden a efectuar ahorros de energía mediante el análisis de calidad de energía y lumínica en base a este análisis se implementó un banco de capacitores que ayudo a mejorar el factor de potencia de 0,87 a 0,95 y se sustituyó lámparas fluorescentes por LED optimizando el nivel de luminosidad dentro de los niveles permitidos, efectuado esto se redujo 8 807.69 kWh/año y disminuyo las emisiones de dióxido de carbono en 1 688,43(kg/CO2/año).

“…With the knowledge of the previous summary statistics and clustering analysis, a range of energy key performance indicators can be studied for case communities [7,8,27,28], such as site maximum peak demand in a year (kW), site electricity use per bed per day (kWh/bed/day), energy use per bed per cooling degree day (kWh/bed/CDD) and energy use per bed per heating degree day (kWh/bed/HDD).…”

“…Aged care facilities' energy use intensity or energy key performance indicators (KPIs) are often related to a site's total energy use, energy use per bed or per unit floor area [7,8,26,27]. These KPI studies can help support energy management decision making and investment [28,29].…”

Aged care communities have been under the spotlight since the beginning of 2020. Energy is essential to ensure reliable operation and quality care provision in residential aged care communities (RAC). The aim of this study is to determine how RAC’s yearly energy use and peak demand changed in Australia and what this might mean for RAC design, operation and energy asset investment and ultimately in the healthcare plan for elderly residents. Five years of electricity demand data from four case study RACs in the same climate zone are analyzed. Statistical tools are used to analyze the data, and a clustering algorithm is used to identify typical demand profiles. A number of energy key performance indicators (KPIs) are evaluated, highlighting their respective benefits and limitations. The results show an average 8% reduction for yearly energy use and 7% reduction for yearly peak demands in the COVID-19 year compared with the average of the previous four years. Typical demand profiles for the four communities were mostly lower in the pandemic year. Despite these results, the KPI analysis shows that, for these four communities, outdoor ambient temperature remains a very significant correlation factor for energy use.

“…Healthcare facilities are often energy intensive due to 24/7 operation and their needs to ensure quality service delivery [7,8]. In aged care communities, there are often air conditioned public and private spaces, catering services, laundry services, a dining hall, activity areas, and library facilities, as well as spaces for offices, nurses or for allied health provisions.…”

Communal living for older people exists in many different forms, such as suburban communities, lifestyle communities, retirement villages and residential aged care communities (RAC) where electricity is supplied via a main gate meter to the whole community. Australia’s Small-scale Renewable Energy Scheme incentivizes individuals and businesses to install renewable energy systems up to 100 kW peak. A system of this size, however, may not meet a community’s energy needs or sustainability goals. In contrast, other residential dwellings are allowed to install a minimum solar inverter of 5 kW. Therefore, this paper investigates small-scale renewable energy targets on a per bed basis for RACs and the impact of a change from the current 100 kWpeak small-scale renewable energy policy. A data driven clustering-based method has been implemented to identify financially optimal photovoltaic (PV) system ratings for ten RACs across four climate zones. Explored are 100 kWpeak PV and net zero electricity scenarios. Results show RACs with 5 kW PV per bed can move closer to a net zero electricity goal and generate 800 to 1400 GWh of renewable electricity each year with significant financial savings. A fairer renewable policy, based on kilowatts per bed, is advocated to improve communities’ energy resilience, financial sustainability, and environmental sustainability.
