1. More than 98% of the materials in the wooden cubic integrated house can be recycled
2. Can be built multiple times
3. No construction waste during construction
4. No paint, no formaldehyde
PK
1. Extensive deforestation
2. Recyclable, but very low collection rate
3. Large amounts of construction waste and powder are generated during construction
4. It is inevitable to paint, there is formaldehyde pollution, and indoor formaldehyde is seriously harmful to the human body
1. The recycling of plastic sheets can release a large amount of toxic gases, causing pollution to the environment
2. It takes more than 100 years for plastics to degrade naturally, with a low environmental protection index
1. Manufacturing requires a large amount of steel
2. In order to prevent corrosion and rust, paint is required. There is formaldehyde pollution.
Factory production and modular installation can effectively reduce logistics costs and improve on-site installation efficiency. Five workers can complete at least one set per day
2. A project can be opened for business within 30 days
3. Some apartment types can be hoisted
PK
1. The construction period is long, and the construction of water, electricity, HVAC, etc. must be calculated separately
2. The construction period of a single project is generally more than 150 days
1. Short construction period, can be hoisted
2. Less construction waste
1. Short construction period, can be hoisted
2. Less construction waste
1. Strong woodiness, close to nature
2. The appearance is diverse and good-looking, will not produce aesthetic fatigue, and the interior design is comfortable, reaching the standard of more than four stars
3. It has good sound insulation effect and good thermal insulation performance
4. Color changes and various combinations make it easy to design different decorative effects
PK
1. Natural wood has a natural texture, but generally lacks small color changes and matching
Step 2 Feel comfortable close to the body
1. Fragile, poor comfort
2. Generally no thermal insulation, high energy consumption for air conditioning
1. Poor thermal insulation, high specific heat of steel, not to mention skin feel
2. Noise on rainy days
3. High energy consumption of air conditioning
1. Steel skeleton structures can effectively cope with various severe climates
2. Professional exterior wall panels do not deform, fade, or crack
3. No mildew, no blackening, no termites
4. It will not corrode and can be used in various climates
5. Supporting photovoltaic self-sufficiency system and intelligent central control system
PK
1. Exposed outdoor wood is prone to blackening, cracking and decay
2. Humid climate is prone to mildew
3. Frequent maintenance and high cost
1. Fragile, poor comfort
2. The service life is not high, and the load-bearing safety is not high
3. It is almost impossible to maintain, and it needs to be replaced when damaged
1. Easy to rust and high maintenance costs
2. Fixed size, poor stretchability
