Sustainable electrical energy management

Introduction

Santos Dumont Hospital SDH) belongs to Unimed de José dos Campos (SP), and was designed based on a sustainable model of consumption and production of health services in São José dos Campos (SP) and was designed based on a model sustainable consumption and production of health services. Already in the project phase, between 2007 and 2009, initiatives aimed at energy management for the entire hospital complex were implemented, and real-time electricity consumption meters were installed in the hospital's main cost centers. SDH uses the Administration of Health Technology (ADTS) to align engineering best practices and the needs of patient care providers.

The hospital's contracted electricity demand is 400 XW and the average monthly energy consumption is 150,006 kWh. The refrigeration capacity is approximately 250 TR (refrigeration ton), while the medical compressed air plant and the five vacuum plant have powers of, respectively, 30 HP and 10 HP. There is an emergency electrical power supply consisting of two Cummins generators totaling 1,000 kVA of apparent power.

For clarification purposes, the built area of the hospital is 6.5 thousand square meters spread over a plot of land measuring 7.2 thousand square meters.

The results on the lighting model adopted and the electrical energy used to light the external area of the hospital have been calculated since March 2012. The SDH is located on a tree-lined avenue and practically the entire facade of the institution is made up of a garden and a parking lot with 100 vacancies. And both need to be enlightened.
