I’m a native of Tianjian
(In) the countryside of Daxing, Beijing
There is a special house
In winter there is not a trace of wind in the house
Seventy percent of the annual energy consumption is supplied by solar energy
Think of it as an experimental field
A garden to relax
Ling She (Zero Cabin) is a 400-square-meter farmhouse
The first certified near-zero-energy-consumption rural farmhouse
Won some international awards
China’s only awarded near-zero-energy-consumption rural farmhouse
It’s a typical U-shaped courtyard house in northern China
The owners are brothers
And it’s basically abandoned
Rented it, and worked 8, 9 months on the design
The on-site construction was completed in less than three months
The principle of "near zero energy consumption" is to make the best use of natural energy as possible
Solar energy, ventilation, lighting
The front yard is light wood frame construction
On top of the original wall we added 250mm of insulation layer
Dug out the foundation
And put in 200mm of insulation layer
The roof was also wrapped up tightly
Like the whole house is wearing a cotton-padded jacket
Traditional doors and windows account for only 20% of the area
But 50% of the energy is dissipated through them
A near-zero-energy-consumption house
Lets in solar energy
And keeps the heat in the house
I live here during the winter
Before I go to bed, the room temperature is 22°C
I turn off the energy supply
And the next morning it goes down to 20°C
The heat preservation is very good
Glass hall, as soon as there is sun
The temperature goes up to 20~25°C
In summer it would overheat
So we use Bamboo curtain, color film photovoltaic
On the one hand, it can generate electricity
And it also plays the role of shade
Forming colorful light and shadow
Heat in winter
And cool air in summer
Are supplied by a machine
It requires little energy
Traditional farm house
The annual power consumption per square meter is 80 kilowatt hour
Whereas our house is only 27, 28 kilowatt hour
Photovoltaic tiles do not look very different from traditional tiles
Glass, with photovoltaic power generation material in the middle
Rely on solar energy to generate electricity
If you can’t use up the electricity generated during the day
Register at State Grid Corporation of China
I can’t use up my electricity
So I can make money on selling the extra
There are three yards in Zero Cabin
An art installation made of (flexible) photovoltaic paper is in the front yard
You can charge your phone at the interface
A water yard in the middle
Collects rain from the roof
The rooms in the back are turned into an 80-square-meter apartment with two bedrooms and one living room
Premade modules in the factory
The installation on the site took just one day
The original wall painting was buried inside (the insulation layer)
In order to pass on the original memory
We kept a few holes
And repainted it
Interior decoration uses mostly recycled materials
Zero carbon garden
All landscape materials are recycled waste
Villagers come to visit the house
They love the house warm in winter and cool I summer
The swing is popular among kids
The house is built for research
But also for actual use and life
My work is busy in Tianjin
When I come here, I’d read and paint
Check on the monitoring system
Many of my friends came over partying
They were amazed by such a house
Especially the fact that it’s in the countryside
The overall transformation, decoration, furniture
The total cost is 2.8 million
The cost per square meter is 600 yuan higher
Than traditional city apartment
In the near future
The cost will decrease
When we talk about beautiful countryside, people think of “beautiful”
But in total China
The more important thing is life quality
They should be able to enjoy a comfortable and healthy living condition
