In China alone, there is a large marked for energy efficient buildings. China, as many other countries, have to increase the energy efficiency in the new buildings to reach their ambiguous climate goals. In 2009, China overtook the United States to become the largest energy consumer in the world. The energy-related carbon emissions in China was projected to increase by 64 % between 2007 and 2050, but to reach China’s Paris Agreement pledge they must be reduced by 60-65 % by 2030. Buildings were responsible for over 30 % of total Chinese energy consumption in 2010. This number is projected to increase to nearly 40% by 2020, the same level as the average in the world.
Around 2 billion square meter new buildings are completed every year in China. Modular construction reduce the construction time, material waste and building costs. The buildings can be produced rapidly in large quantities and easily shipped on ships and trucks to meet the world’s need for energy efficiency buildings at a reasonable price. 1.2 billion people in the world are still without access to electricity today.
