Which type of building code focuses on energy efficiency?

The correct answer is the type of building code that specifically addresses energy efficiency, which is energy codes. Energy codes are designed to establish minimum standards for the energy performance of buildings. They focus on various aspects such as insulation, heating and cooling systems, lighting, and overall energy consumption, with the goal of reducing energy costs and environmental impact.

These codes play a crucial role in promoting sustainability and ensuring that buildings use energy efficiently, thereby contributing to lower greenhouse gas emissions and helping to combat climate change. Energy codes often incorporate guidelines for renewable energy sources and the use of energy-efficient materials and technologies, ensuring that new constructions and remodels adhere to the latest standards in energy efficiency.

In contrast, safety codes primarily concern the safety and health of building occupants, outlining regulations to prevent hazards. Structural codes focus on the integrity and stability of the building's framework, ensuring that it can withstand various loads and environmental factors. Accessibility codes are aimed at making buildings usable for individuals with disabilities, ensuring compliance with regulations such as the Americans with Disabilities Act (ADA). While all these codes serve important functions, energy codes are specifically tailored to enhance energy efficiency in buildings.
