Lightweight steel frame villa realizes sustainable living

Lightweight steel frame villa has become a benchmark solution for realizing the goal of “carbon neutrality” in the field of green building through the three core elements of high recycling rate materials, low pollution process and circular economy model.

I. Environmental friendliness and recycling of materials

High-strength recyclable steel: the main body is made of G550-grade aluminum-zinc-plated steel, with yield strength ≥550MPa and corrosion-resistant life of more than 50 years, and the steel can be 100% recycled after dismantling, which reduces the consumption of natural resources.

Composite ecological building materials:

The wall is filled with glass fiber cotton (heat transfer coefficient ≤ 0.3W/(m²-K)), with calcium silicate board to achieve 65dB sound insulation performance;

The exterior wall is made of wood-plastic hanging boards or recycled cement fiber boards, which reduces production energy consumption and carbon emissions.

Zero-pollution construction: factory prefabrication rate exceeds 90%, on-site dry assembly reduces construction waste by 80% and avoids dust and wastewater pollution of traditional wet work.

II. Energy-saving design and energy self-sufficiency

Passive energy-saving technology:

Optimize the orientation of the building and the proportion of open windows, and use natural ventilation to reduce air-conditioning energy consumption (energy-saving rate ≥ 30%);

Integrated photovoltaic power generation tiles on the roof (average daily power generation of 15kWh/㎡) to meet the basic electricity demand of the family.

Active energy management:

Ground source heat pump system + energy storage device, winter heating cost as low as 8 RMB/㎡, comprehensive energy saving of 65% throughout the year;

Rainwater recycling system (daily processing capacity ≥ 2 tons), used for irrigation and bathroom flushing, water saving rate increased by 40%.

III. Eco-friendly and Healthy Habitat

Low-intervention construction: pile foundation adapts to complex terrain (mountains, wetlands, etc.), reducing the damage to the original landform by earth excavation.

Healthy environment control:

PM2.5 filtering fresh air system + Low-E glass curtain wall, indoor air quality is 3 times better than outdoor;

Formaldehyde-free environmental paint + plant fiber acoustic panels, VOC emissions ≤ 0.03mg/m³.

Vertical greening integration: drought-resistant plants are planted on the roof and façade, cooling down 3-5℃ in summer and reducing the heat island effect.

IV. Economy and Social Benefits

Full life cycle cost optimization:

Comprehensive cost of 1500-2500 RMB/㎡ (including intelligent system), 15%-20% lower than traditional buildings;

Maintenance costs are reduced by 60%, and steel and building materials recycling proceeds can cover demolition costs by 30%.

Policy Driven and Certified:

New rural construction subsidies (up to 120 RMB/㎡) promote rural popularization;

Priority for urban projects to obtain three-star green building certification (carbon intensity ≤15kgCO₂/㎡-per-year)

V. Lightweight steel-framed villa advocates green lifestyle

Pollution control during construction

The prefabrication rate of the factory is over 90%, and the dry assembly process is adopted on site, which reduces 80% of dust, waste water and construction waste 68.

Edge materials and packaging materials generated from construction can be classified and recycled, realizing “zero-pollution” construction68.

Disposal of materials after dismantling

Metal components such as light steel keel and connectors can be 100% recycled, and the recycling revenue can cover 30% of the demolition cost58.

Non-metallic materials (e.g. calcium silicate boards, wood-plastic boards) can be converted into road base materials or raw materials for new boards through crushing and recycling technology, with a comprehensive utilization rate of over 70%.
