Integrating Renewable Energy Storage with Solar, Including Micro-Grid Functionality in Modern Healthcare Buildings

Abstract

This research focuses on three major Turkish hospitals case studies to demonstrate how input parameters for renewable energy internal load and temperature control patterns influence the accuracy of annual energy simulation results for healthcare buildings using micro-grid lines. The three cases studies include: The Central Hospital Istanbul and the Medicana International Hospital Building, both part of the state hospitals, and the Koc Hospital Istanbul Building. These specific case studies are selected to represent three different types of buildings with enhancing energy capacity with renewable energy (solar and wind). The Koc Hospital Istanbul is an example of a new certified building. The Central Hospital Istanbul provides an example of a small retrofit project, and the Medicana International Hospital is an example of a building that has gone through major retrofitting for energy management. This research uses MATLAB, an interface of MATLAB to simulate all case studies for renewable energy generation with micro-grid lines. The program offers the option to model the building with simple or detailed HVAC systems. It has built-in templates for renewable energy management, weather data, typical loads, and schedules. For renewable energy, the modified model achieved a lower accuracy in heating energy than in renewability. However, it is still a substantial improvement over the default model.
