JEB’S CONTRIBUTION
Materials & Resources (M&R)
MRc4
Building Product Selection and Procurement
Up to 10 pts
Multi-attribute product qualification applies in full — low embodied carbon, recycled content, low VOC emissions, and supplier take-back. Under ID+C, MRc4 carries a significantly higher ceiling (up to 10 points versus 5 under BD+C), reflecting the centrality of interior product selection to fit-out sustainability performance. JEB’s wedge-key dry-assembly system minimises offcut and installation waste. Recyclable aluminium, glass, and packaging materials are designed for segregated waste streams, with supplier take-back available.
MRc5
Construction and Demolition Waste Diversion
4 pts
Under ID+C this credit is worth 4 points versus 2 under BD+C.
Indoor Environmental Quality (IEQ)
EQc1
Enhanced Air Quality
2 pts
Formaldehyde emissions below 20 µg/m³, independently tested per ISO 16000-6, satisfy the enhanced IAQ material thresholds under EQc1, a credit specific to the ID+C rating system.
EQc2
Occupant Experience
Within 7 pt credit
Contributes to two sub-strategies within EQc2:
• Sound Environment: High STC-rated assemblies support acoustic-criteria mapping and speech privacy across occupied spaces; available where acoustic strategies are met in ≥75% of spaces. • Lighting Environment & Quality Views: Glazed configurations (VLT >40%) provide occupant access to natural daylight and exterior views, supporting visual comfort and lighting pathways. VOC emission data (TVOC <500 µg/m³; formaldehyde <20 µg/m³), tested per ISO 16000-6 and ASTM D5116-10, supports pre-occupancy air- quality testing submissions. Under ID+C, this credit is worth 4 points versus 2 under BD+C, reflecting the significance of interior product emissions to occupant health in fit-out projects.
