Analysis of Electrical Energy Management Performance in Asri Hotel Building

Abstract

The Energy Efficiency Index (EEI) records a building's performance and provides a baseline for energy consumption. Analyzing a power system using EEI involves total energy consumption, electricity consumption for each zone, and energy consumption distribution. This study aims to determine the electrical load profile and building profile of electrical energy consumption at Hotel Asri, analyze the performance of electrical energy use, and provide optimization conclusions. The electrical load profile includes installed loads (computers, TVs, hairdryers, refrigerators), cooling loads (Air Conditioning), lighting loads, and other loads (pumps, water filters). Hotel Asri's building area is 3446 m², with an average total electrical energy consumption of 39.98967 kWh per year. After measuring Light Intensity and calculating installed and cooling loads, the IKE calculation for buildings with air conditioning is 7.8 kWh / m² per month (highly efficient) and without air conditioning is 1.19 kWh / m² per month (highly efficient). The IKE of the entire Asri Hotel building is 139,225 kWh/m² per year, below the IKE target for hotels. Although Hotel Asri's IKE is highly efficient based on Indonesian building standards, many lighting measurements do not comply with the Indonesian National Standard for artificial lighting (SNI 03-2496-2001).
