STRATEGY FOR A NET ZERO BUILDING

Significant Energy Reduction (60%)Early planningHigh efficiency HVAC systemsExtra insulationDay-lighting

Energy efficient lighting and controlsEnergy productionEnergy storage

*Achieving the final 40% is a challenge!

Requirements for Net ZeroMulti-trade solutions that incorporate new technologies.

MULTI-TRADE SOLUTIONS

Growing Trend in Multi-Trade Solutions

BIPV Example:Photovoltaic engineering and designDC electrical engineering and designStructural curtain wall engineering and design

Manufacture Photovoltaic curtain walls and rain screensInstallation and final commissioning for the system

Future Possibilities:Hot water from the exterior envelopeCaptured warm air from exterior envelopeLED lights powered by PV on sunscreensDay-lighting technology included in vision areasBuilding controls with smart envelopes, operable windows,

sunshades and smart glass

DC lighting solutions to eliminate the use of inverters

24/28

BiPV ROOFTOP vs VERTICAL ARRAYS

Rooftop arrays with standard orientation compared to the

performance of four BiPV Systems over Fourteen months ofmonitored data shows vertical wall performance equals

72% of rooftop array.


25/28

VISION vs SPANDREL GLASS

At this time, the cost effectiveapproach to a BiPV curtainwall is to use insulating glassin the vision conditions andphotovoltaic panels in allspandrel conditions. The cost of transparent

photovoltaic panels is 8-20times more than standardutility grade panels.

The performance values dropto 10% of the utility gradepanels.

Solution - use Utility Gradepanels in spandrel areas anduse BiPV sunscreens toimprove SHGC and increasesurface area of PV on the wall.

GOVERNMENT INCENTIVES AND REBATES

Federal tax credit, 30% of BiPV in first yearMACRS accelerate depreciation, reduces full

depreciation time from 39 years to 5 years

Local utilities offer substantial incentivesEnergy production for 25 years100% payback in 24 months
