Integrated houses provide quantifiable solutions that meet national standards through industrialized manufacturing and modular technology in the residential housing field. The core advantages are reflected in four points: structural safety performance adopts cold-bent thin-walled steel frame, seismic grade of 8, fireproof A1 grade rock wool filling wall, and service life of more than 50 years. Living comfort guarantee, 150mm polyurethane insulation layer achieves indoor 20℃ constant temperature in extremely cold areas of -25℃, external window heat transfer coefficient ≤1.8W/(㎡·K), multi-layer composite sound insulation wall noise reduction ≥35dB. Construction efficiency is improved, the factory prefabrication rate is more than 85%, and the on-site assembly shortens the construction period by 60% compared with traditional construction. The residential project in Xiongan New Area has achieved 7-day single-story residential hoisting and capping. Cost and environmental control, standardized production reduces material waste by 30%, assembly labor demand is reduced by 40%, 95% of component materials are recyclable, construction waste is reduced by 80% (compared with cast-in-place houses), and pre-installed photovoltaic roof systems reduce residents' energy consumption by 30%. In scenarios such as government affordable housing (such as the Shenzhen Changzhen project that delivered 2,740 units in 112 days), new rural reconstruction (the sloped residential complex in Anji, Zhejiang), and urban renewal, the Ministry of Housing and Urban-Rural Development's "Prefabricated Building Evaluation Standards" A-level certification parameters and verifiable engineering cases have become a pragmatic choice to meet living quality and policy compliance requirements.
