Under the dual improvement of policy increase and cost reduction, the photovoltaic building integration industry is expected to usher in new development opportunities.

For a long time, China's architecture has faced the problem of high energy consumption and a large proportion of high energy consuming buildings. Data shows that currently, the carbon emissions during the operation of domestic buildings account for over 20% of the total carbon emissions in the country.

With the continuous implementation of the "dual carbon" goal, various industries have begun to explore the path of energy conservation, emission reduction, and carbon reduction, and the construction industry is no exception. Reducing building energy consumption and developing green construction have gradually become industry consensus.


 

Focusing on building energy conservation, policies are being strengthened layer by layer

In 2022, the Ministry of Housing and Urban Rural Development issued the "14th Five Year Plan for Building Energy Efficiency and Green Building Development", which clearly stated that by 2025, new urban buildings will be fully built into green buildings, with steady improvement in building energy utilization efficiency and gradual optimization of building energy consumption structure.

In addition, the National Development and Reform Commission has issued the "Implementation Opinions on Promoting Consumption Expansion, Quality Improvement, and Accelerating the Formation of a Strong Domestic Market", proposing to focus on promoting green consumption and creating green shopping malls with the supply of green products, construction of green public transportation facilities, energy-saving and environmentally friendly buildings, and related technology.

On March 11, 2022, the Ministry of Housing and Urban Rural Development issued the "14th Five Year Plan for the Development of Housing and Urban Rural Construction Technology" (referred to as the "Plan"), which mentioned the integration of efficient and intelligent photovoltaic buildings.

It is not difficult to see that driven by the dual carbon goals, China's architecture is gradually moving towards greenery.
 

Classification of photovoltaic building integration

Among numerous energy-saving technologies in buildings, building photovoltaics have become an important driving force for energy transformation and have attracted widespread attention. This is a technology that integrates solar power (photovoltaic) products into buildings.

The integration of photovoltaic buildings can be divided into two categories: one is the combination of photovoltaic arrays and buildings. Another type is the integration of photovoltaic arrays with buildings. Such as photovoltaic tile roofs, photovoltaic curtain walls, and photovoltaic lighting roofs.


 

Various applicable building forms

Photovoltaic building integration is suitable for most buildings, and can be installed in common buildings such as flat roofs, sloping roofs, curtain walls, and ceilings.

Installing a flat roof at a specific angle can achieve maximum power generation and optimal economic benefits; The southern sloping roof is second, while the photovoltaic curtain wall and photovoltaic ceiling play a role in enhancing the social value of the building.
 

Commercial Application of Building Integration

The role of photovoltaic building integration in reducing building energy consumption is very prominent, so China is vigorously promoting the commercialization of photovoltaic building integration. According to statistics, China currently has an existing building area of about 80 billion square meters, and at the same time, nearly 100 million square meters of new daylighting tile roof areas are added to the market every year. Once it moves towards large-scale application, the integration of photovoltaic buildings will be a market of nearly trillion yuan.
