Why do developers use glass curtain walls?

Ten years ago, Mr. Wang refused to believe in it: “Glass curtain walls are 300 yuan more expensive than cement, only fools would use them!”

Now all his new projects are glass curtain walls, and he also told the design institute: “Open more windows! Make it more transparent!”

This is not about following the trend of aesthetics, but an upgrade in the cognition of the money-making efficiency brought by glass curtain walls.

1. The beauty of glass curtain wall: let the real estate have “Internet celebrity genes”
1. Appearance is traffic
Case: A real estate gradually became an Internet celebrity attraction because of the glass curtain wall on the facade
Result: The sales office was packed on the opening day, and the price was 25% higher than the surrounding area and still daylight

2. Double the degree of design freedom
Limitations of traditional paint exterior walls:
Only flat surface|Color fades in ten years|Modeling depends on relief

How to play with glass curtain wall:
[Curved glass] → Create the space feeling of Galaxy SOHO
[Colored glaze printing] → Print “Fuchun Mountain Residence” on the building
[LED embedded] → Transform into a giant city billboard at night
“In the past, selling houses relied on floor plans, but now it relies on curtain wall renderings”
——Marketing director of a real estate company

2. Practicality: “all-round player” that saves worry and money
1. Lifespan crushes traditional exterior walls
The service life of glass curtain walls far exceeds that of traditional exterior walls,

2. Build a building like building blocks
The magic of unitized curtain wall:
Factory prefabrication: the construction site becomes an “assembly workshop”
Installation on rainy days: construction period shortened by 1/3

3. Automatically adjusted smart skin
Benefits of glass curtain wall
Summer: glass curtain wall can reduce air conditioning and save electricity
Winter: increased light transmittance and solar greenhouse save heating
Rainy days: self-cleaning nano coating saves high-altitude cleaning fees

III. Investment value of glass curtain wall
1. Rent premium
[Comparison of office rents in the same area]
Old building with painted exterior wall: ¥4.2/㎡/day
New building with glass curtain wall: ¥6.8/㎡/day
62% difference!
2. Policy dividend harvester
What glass curtain walls can “pick up”:
Plant area ratio bonus: 5,000 square meters more due to light transmittance reaching the standard

3. Secrets to second-hand valuation jump
Unspoken rules of the appraisal company:

Building A with smart curtain wall = annual rent × 22 times valuation
Building B with traditional exterior wall = annual rent × 15 times valuation

IV. Pitfall avoidance guide: Don’t touch curtain walls in these three situations
Glass curtain walls are good, but be careful in three types of projects:

Small county commercial buildings:
→ Tenants cannot afford the premium → Cleaning fees eat up profits

Sandstorm-prone areas:
→ Accelerated aging of sealing strips → Annual maintenance fees increase by 3 times

Ultra-low budget housing:
→ Owners are more concerned about the room rate → Glass curtain walls have become a point of complaint

The future has arrived: glass curtain walls are evolving in this way
Power-generating glass: The curtain wall of a building in Shanghai generates 870,000 kWh of electricity per year, enough to illuminate the entire building

Broken glass becomes a screen: A Guangzhou project uses curtain walls to broadcast the World Cup, earning millions of dollars in advertising revenue per month

The account that developers must calculate:
Assuming the project is 10,000 square meters, the curtain wall is 300 yuan/square meter more expensive than the paint → the cost increases by 3 million
But as a result:
Annual rent increases by 4.8 million (at a premium of ¥4/square meter/month)

Speaking of this, you finally understand why developers use glass curtain walls, right? If you happen to want to do exterior wall decoration, you might as well take a look at glass curtain walls or compare them more in the early stage to avoid unnecessary waste of funds.
