With solar power alone, all power supply including heating and electricity can be guaranteed in the Zero Energy Building, said a representative of green architecture in north China’s Tianjin Municipality.
“No matter how cold the weather is, the whole building might always maintain constant temperature and humidity,” said He Rui, a staff member at State Grid’s Binhai branch in Tianjin, one of the developers.
“Taking into account the roof structure, the angles of the beams and the surrounding environment, we installed 60 PV panels with a total of 20 kilowatts. Under proper lighting conditions, the PV system can generate 60 kilowatt-hours of electricity every day.” “, he indicated.
According to He, the building’s renewable energy production capacity is greater than or equal to its energy consumption, allowing it to achieve “zero energy consumption” without any external energy input.
The white building, which covers more than 130 square meters, represents a small step in China’s continued national efforts to follow a path of green development, as the country aims to peak carbon dioxide emissions before 2030. and achieve carbon neutrality before 2060.
China launched its national carbon trading market, the world’s largest in terms of the amount of greenhouse gas emissions covered, on July 16 last year, marking a significant step toward reducing its carbon footprint and meeting emission targets.
The market ran for 114 trading days in 2021, reporting a total trading volume of 179 million tons and a turnover of nearly 7.7 billion yuan (regarding 1.2 billion US dollars), the Shanghai Environment and Energy Exchange said. .
North China’s Inner Mongolia Autonomous Region started a large-scale photovoltaic power construction project in the Kubuqi Desert, the country’s seventh largest desert, last October, which is estimated to reach a total installed capacity of regarding two gigawatts.
Located in the city of Ordos, the project is expected to cover approximately 6,700 hectares and reach its full grid-connected power generation capacity before the end of 2023.
The project will bring an annual average of more than 4.1 billion kilowatts of electricity to the grid, helping save more than 1.25 million tons of standard coal or reducing 3.4 million tons of carbon dioxide emissions.
Compared to thermal power, new power generation has brought a total emission reduction equivalent to afforestation of 180,000 hectares so far in Inner Mongolia.
The construction of a zero-carbon industrial park in the city of Ordos has been accelerated. The park, which includes fan equipment manufacturing, battery production and a hydrogen energy industrial chain, is expected to reach an annual output value of 100 billion yuan following it comes into operation this year.

“80 percent of the energy in the park comes directly from wind power, photovoltaics and energy storage. The other 20 percent benefits from a cooperative pattern in which surplus energy is sold to the grid. when too much energy is produced, and the stored green energy will be recovered from the grid when needed,” said Zhang Lei, CEO of Envision Group, developer of the park.
“In this way, we might achieve 100 percent carbon-free power supply while ensuring safe and low-cost electricity consumption,” Zhang said.
