Energy Savings
Simulations are provided through green remodeling of old buildings and energy-saving guides for apartment complexes in the local area.
Rather than merely improving building exteriors, simulations focus on green remodeling that addresses the climate crisis and promotes a sustainable environment.
Detailed building and energy consumption data, often difficult for users to access, are automatically analyzed to provide convenient cost estimation and savings potential.
Additionally, users can compare energy consumption of their neighborhood complex with surrounding complexes and explore measures to reduce energy costs.
Green Remodeling Simulation
Green remodeling is a method to save building energy and reduce carbon emissions by enhancing the energy efficiency of existing buildings through remodeling.
Our platform conducts building energy simulations based on actual energy usage for buildings located in Gyeonggi-do. Building energy simulation results calculate energy consumption, carbon emissions, and energy costs, demonstrating the effects of green remodeling.
The evaluation process comprehensively considers factors affecting energy consumption, such as building shape, lifespan, and facilities. In particular, citizens can reflect building characteristics by selecting facilities and inputting energy usage data. This enables more accurate energy simulations and assesses their impact on buildings.
"This information provides citizens with the effects of green remodeling and guides reasonable improvements under various scenarios."

Building Green Remodeling Simulation Process
The Gyeonggi building green remodeling simulation process consists of six steps, utilizing building ledger information and energy usage data from the Real Estate Agency. By applying the building energy simulation developed by the U.S. Department of Energy, approximately 360 simulations are performed according to building use, providing energy improvement measures through green remodeling.

Apartment Complex Energy Saving Simulation
View the energy consumption status of our complex at a glance
We provide information that allows you to see, at a glance, the energy consumption status of your complex and surrounding complexes.
Provides information on the complex’s electricity bills, heating and cooling efficiency ratings, energy usage, etc.
View your apartment’s electricity consumption status at a glance
This service allows you to check at a glance your apartment’s KEPCO contract power, contract type, and monthly electricity consumption, comparing it with neighboring complexes.
Energy Saving Guide Provided
We provide guidance on energy saving, including contracted power, peak rate, progressive electricity rate management, solar installation effects, and public electricity improvement for the complex.

Progressive Electricity Bill Management
Unlike regular houses, most apartment complexes apply a progressive rate system to communal electricity. If the average electricity usage exceeds 400 kWh in the 3rd progressive level by even 1 kWh, all households’ shared electricity bills increase by about 5,000 KRW, making 3rd-level management important.
Solar Power Bill Reduction Effect
Even if the installed capacity and electricity production of apartment solar generators are the same, actual electricity bill savings vary by complex. This is because electricity produced in apartments is generally not traded with KEPCO but offset against the electricity used in the complex. Complexes with higher electricity usage benefit more from shared electricity bill reductions through solar power.
Check Public Electricity Consumption
If your apartment’s public electricity bill is unusually high, it is necessary to check whether the KEPCO contract method is appropriate and if there is no wasted electricity consumption.
Smart Electricity Meter Installation Apartment Information
Through information on apartment complexes in Gyeonggi-do equipped with smart meters, you can access exclusive energy services available only to your complex. Complexes with smart meters can anticipate using electricity rates without progressive charges in the future via the introduction of a selectable rate system.
Gyeonggi Citizen Power Plant Service
If your apartment has a smart meter, you can participate in the Citizen Power Plant service, reducing coal power plant operation by collectively saving electricity at specific times, such as peak hours. This year, we plan to recruit participating complexes through a pilot project and encourage your interest.
Comparison of Power Consumption by Period
If this summer was very hot, how much has our complex’s electricity usage increased compared to neighboring complexes? Through the platform, you can easily analyze monthly electricity consumption data for approximately 4,000 apartment complexes in Gyeonggi-do, including data from the past two months.
