New Energy Applications in Building Energy Efficiency: Progress and Prospects

Abstract

With increasing global attention on the utilization of new energy technologies and energy conservation, the application of new energy in building energy efficiency has become a key direction for the future development of the construction industry. This paper consolidates several common new energy technology application scenarios, including solar air conditioning, solar water heating systems, ground-source heat pumps, and radiant floor heating. Focusing on solar and geothermal energy which is the two most widely used energy sources in building energy efficiency, the study analyzes their working principles, compares their advantages and disadvantages, and evaluates their effectiveness in energy conservation. It also examines challenges such as high costs, low adoption rates, and immature technologies in the integration of new energy with buildings. Development strategies and future research directions are proposed to advance the application of new energy in building energy efficiency, offering new methods and ideas for future energy-saving efforts in construction.
