A Novel Strategy for Converting Conventional Structures into Net-Zero-Energy Buildings without Destruction

Abstract

The majority of energy consumption is attributed to buildings. Buildings designed with environmentally sustainable features have the potential to reduce energy consumption. The demolition of ecologically detrimental structures incurs expenses and damages the natural environment. The act of constructing models for the purpose of destruction was deemed superfluous. The replication of the structural model was accompanied by a modification of the design, and a variety of tactics were employed. The proposed upgrades for the building include the installation of new windows, incorporation of greenery on the walls and roof, implementation of insulation, and integration of solar panels in a four-story residential building in Najran, Saudi Arabia. Simultaneously installing insulation prior to changing windows will ensure that the energy consumption of the building, green wall, or green roof will remain unaffected. The installation of solar panels on the walls and top roof of a structure has the potential to generate a monthly electricity output up to two times greater than the structure’s consumption. The spas can be heated on a daily basis by substituting the heating system with solar collectors. The implementation of sustainable building practices has resulted in a significant reduction in energy consumption. Specifically, electricity, gas, heating, and cooling consumption decreased by 11%, 85%, 28%, and 83%, respectively.
