建筑节能技术的推广与应用（英文中文双语版优质文档）
With the continuous aggravation of global climate change, energy and environmental issues have become the focus of attention. The construction industry is a major industry that consumes global energy. How to reduce building energy consumption and impact on the environment has become a key issue facing the global construction industry. In this context, building energy-saving technology has been widely concerned and applied.
1. The development history of building energy-saving technology
The development of building energy-saving technology can be traced back to the 1970s, when, due to the impact of the energy crisis, people began to pay attention to energy-saving issues. Since then, building energy-saving technology has gradually developed, and after decades of development, important progress has been made. The development of building energy-saving technology can be divided into the following stages:
1. The first stage: 1970s to 1980s
From the 1970s to the 1980s, people began to pay attention to building energy conservation. The main energy-saving measures adopted included adding heat insulation layers, installing energy-saving glass, and adopting energy-saving lamps.
2. The second stage: 1990s to 2000s
From the 1990s to the 2000s, building energy efficiency technologies were further developed. In addition to adopting traditional energy-saving measures such as heat insulation and lighting, advanced building energy-saving technologies such as solar energy and ground-source heat pumps have also been introduced.
3. The third stage: the 21st century

Since the 21st century, building energy-saving technologies have been further developed and promoted. Governments and enterprises of various countries have begun to adopt more advanced technologies to improve building energy-saving level
s, such as the use of high-efficiency heat insulation materials and building integration technologies.
