  3. 3. Why does it matter? • Codes demand it • Substantial portion of construction budget – 20% range • Integration with HVAC requires that the building envelope perform • Sustainable buildings often incorporate innovative assemblies and materials • Envelope failure can require costly repairs to re-establish the design intent • Envelopes are complex systems with shared responsibilities and are not typically commissioned SB-10 – THE ENVELOPE ULTIMATUM | 12 OCT 2012
