Due to the high energy use and greenhouse gas emissions in the building sector, the government recently revised its 2030 GHG reduction roadmap, raising the reduction rate from 18.1% to 32.7% compared to the BAU. However, although the new and renewable energy sources under the Act on Promoting the Development, Use, and Distribution of New and Renewable Energy can be considered to be diverse in 12 fields, in fact, the application to buildings in the new and renewable energy facility system is currently limited to only 7 fields due to the recent addition of small wind power. Therefore, it is necessary to create a market for new and renewable energy for various applications in buildings. Accordingly, in this study, as the obligation of zero-energy buildings approaches, we will approach the possibility of using the electric energy produced through horizontal drainage wheels by using the drop of drainage energy infinitely from the drainage pipe in the building.
