📋 Tender Overview
The National System of Technical Assessments of Innovative Products and Conventional Systems (SiNAT) of the Brazilian Habitat Quality and Productivity Program (PBQP-H) had new technical documents and Protocol and Guideline revisions approved. The SiNAT Working Group (GT-SiNAT) met in the first week of November and approved two new Technical Assessment Documents (DATecs), a review of SiNAT Guideline No. 013 (Recycled HDPE Corrugated Pipes) and a review of the Thermal Performance Assessment Protocol.
Among the updates are guidelines for the use of pipes produced with recycled material and improvements in the criteria for evaluating the thermal performance of buildings. With these approvals, new products or systems will be adequately evaluated regarding thermal performance in buildings, as the Assessment Protocol has been revised and already considers the updated classification of bioclimatic zoning, explains the Senior Infrastructure Specialist of the Management and Innovation Coordination, of the National Housing Secretariat, Jose Sergio dos Passos Oliveira.
These changes expand technological options and reinforce the search for quality, innovation and sustainability in construction. The work of the SiNAT working group contributes to significant advances in the civil construction sector, reinforcing the diversity of construction solutions approved by the PBQP-H, focusing on the needs of beneficiaries of housing units, as well as ensuring compliance with safety, habitability and sustainability requirements.
The GT-SiNAT was attended by representatives of Technical Assessing Institutions (ITAs), members of the board and SiNAT experts.
Check out what was approved below:
1. Revision of SiNAT Guideline No. 013 - Corrugated polyethylene pipes containing recycled high-density polyethylene for rainwater drainage
Redefines requirements for pipes intended for microdrainage in internal areas of residential and commercial developments, aligning with best sustainability practices.
The first revision of SiNAT Guideline no 013 expanded the scope of use, allowing the use of the pipe in rainwater drainage in general and not just in condominiums.
2. DATec no 052 - FastFlex Construction System of prefabricated modules in light structural steel profiles and closure in thin sheets
After technical evaluation and assessment by experts, the FastFlex Construction System was approved by GT-SiNAT, approved through . FastFlex is a construction system made up of prefabricated modules in light structural steel profiles with thin sheet closures.
The prefabricated module consists of a structural chassis (beams and pillars) made of galvanized steel profiles, cold formed (according to ABNT NBR 6323) and welded. The system is recommended for use in single-family single-family housing units, detached or semi-detached, and multi-family housing units with two floors, detached and semi-detached.
3. DATec no 053 - Pre-molded Structural Panels - MODULAR CERAMIC PANELS - up to 2 floors
GT-SiNAT also approved, after technical evaluation, the product - Modular Ceramic Panels - up to 2 floors, a construction system composed of mixed structural panels of reinforced concrete and ceramic blocks. It can be used in rural, urban and coastal environments, suitable for buildings with up to two floors (ground floor + 1), detached or semi-detached.
This guarantees the availability of more innovative systems/products in the construction sector, with proof of performance in relation to safety, habitability and sustainability requirements.
4. Review of the Protocol for Assessing the Thermal Performance of Building Systems for Housing by Computer Simulations
The , from 2021, which guides computer simulations to evaluate the thermal performance of homes, ensuring greater precision in the procedures and criteria used by evaluating entities, had its first revision approved at the GT-SiNAT meeting.
The review was necessary to adapt it to the new standard ABNT-NBR 15220-3/2024, which deals with the final performance of buildings, now considering the new bioclimatic zoning.
