The Concept of Green Building in The Application of Solar Panels on the Roof of the House for CO<sub>2</sub> Emission Reduction
The development of sustainable development with the concept of the green building creates environment-friendly and energy-efficient buildings with solar panels as a source of electrical energy, uses energy-saving lamps, uses indoor vegetation, creates noise reduction system, and maintains environment temperature and humidity. The application of green building solar panels is influenced by several factors, such as the intensity of solar radiation, wind speed and direction, humidity, distance and height of surrounding buildings, and the level of pollution from the residential area. This study aims to develop the concept of green building in the application of solar panels on the roofs of residential neighborhoods to reduce CO2 emissions. The analytical method used is descriptive and qualitative analysis, with a literature survey related to the types of solar panels, identifying the conditions of existing houses in the study area, and analyzing the suitability of the space for the placement of the solar panels to be placed by taking into account the provisions of the shape and area of the roof of the house. The results of the analysis stated that the green concept house strategy, for the 86m2 type house at BNP 2 Makassar City, is rated platinum with a score of 77. The real impacts of environment-friendly houses are the installation of renewable energy, replacement of LED lamps, and installation of light sensors. Solar panels produce 19.5% carbon gas emission in a month compared to carbon gas emissions generated from the use of PLN electrical energy by using 10 panels for an 86 m2 house type, which means an 80.5% reduction in carbon gas emission.
