Certified for Low-Carbon Construction by the Low Carbon Building Alliance

Alfa Safe Earthquake-Resistant Techniques apply one-piece bending processes to reinforcement for columns, walls, and beams. This improves construction quality, enhances seismic resilience and reduces material use and waste by eliminating overlaps in traditional rebar systems. It is an alternative solution with lower carbon emissions compared to traditional columns and walls, offering excellent carbon reduction benefits and certified for Low-Carbon Construction by the Low Carbon Building Alliance.

The certified product’s 60-year lifecycle carbon reduction ratio and unit carbon emission are as follows:
●Alfa Safe systemic-column&Alfa Safe systemic-wall in all building:50.0%; Unit carbon emissions: 1.45 kgCO₂e/(m²·yr)
●Alfa Safe dual-core column on the 1st floor+Alfa Safe systemiccolumn&Alfa Safe systemic-wall in all building:47.9%; Unit carbon emissions: 1.36 kgCO₂e/(m²·yr)
●Alfa Safe dual-core column&Alfa Safe systemic-wall on the 1st floor+normal column&normal wall above the 1st floor:5.1%; Unit carbon emissions: 1.88 kgCO₂e/(m²·yr)

●Method Name: Alfa Safe Dual-Core Column Technique

●Development Objective: To simplify construction techniques through prefabricated reinforcement components, effectively reducing labor and time while improving construction quality and building safety.

●Evaluation Results: Based on the submitted documentation reviewed by the Taiwan Architecture and Building Center from November to December 2021, the technique passed the evaluation conducted by the center’s committee. However, compliance with existing regulations on building techniques is required.

The construction technique system, after evaluation, has been proven to achieve the following functions according to its development objectives:
(1)Rectangular columns using this technique retain the original design’s main reinforcement configuration. The stirrups and ties from the original design are reconfigured into a one-piece stirrup system. Through one-piece rebar prefabrication, rebar tying techniques are simplified, improving the quality of reinforcement construction. An internal core column is added to enhance seismic resilience.
(2)A portion of the one-piece stirrups is accurately positioned first. As the main reinforcement of each rectangular column is sequentially arranged, all one-piece stirrups for the column are fitted in place. They are tied securely according to the design's stirrup spacing, with adjustments made after formwork assembly to ensure precise positioning of the column's reinforcement as a whole.
(3)Tests have demonstrated that its strength and toughness surpass those of traditional RC columns. For buildings where all RC columns in the first floor (including the mezzanine floor) adopt this construction technique, seismic safety is significantly enhanced.
