Green Roofs Green roof systems

Two main categories:

• Extensive: 15 psf – 80 psf, typically 4-6 inches deep•Less Maintenance and smaller plants

• Intensive: 80 psf – 150 psf, typically 12 inches deep

Green roof

Page 11: Arts & Humanities Instructional Building

Costs & SchedulingMaterial and Installation Summary:

• Built-up roof @ $1.98 / sf = $ 7,223

• Green roof @ $14.43 / sf = $52,640

Cost Difference: $45,417

Installation Productivity:

• Built-up roof @ 2,000 sq.ft installed per day = 13 days

• Green roof @ 1,800 sq.ft installed per day = 14 days

Conclusion

1.2D + 1.6L + .5S = 145 psf

• ΦVn ≥ Vu • ΦMn ≥ Mu • L/240

Page 13: Arts & Humanities Instructional Building

Mechanical Impact

• Green roof expected heat flow reduction is 20% in summer months

• Greatest thermal savings of a green roof is in summer months

Heat flow calculations Built-up roof: cooling qx = (91-68) * 3,648 / 15.89 = 5,280 btu/hr Green roof savings = 5,280 btu/hr * 20% = 1,560 btu/hr

Why Re-Sequencing?Façade materials

• Curtain wall

• Pre-finished aluminum panels

• Brick veneer
