• First-cost concerns• Demonstrate financial cost-
effectiveness– ROI– Increase in building value– Risk mitigation– Intangibles
• Concern over actual building performance– Projects need continuous
commissioning– Renewables have to work as
planned– Behavioral issues & plug loads
must be managed
ISSUES?
![Page 19: High Performance Building Design Workshop](https://reader031.vdocuments.us/reader031/viewer/2022013011/554e3a3cb4c905f9478b4c0c/html5/thumbnails/19.jpg)
• Widespread low-energy design know-how– Cost premium for good design
getting smaller• More stringent energy codes (US,
EU, AUS)– Reduces first-cost premium for
net-zero– Better products at conventional
costs• Solar power cost
reductions/efficiency gains• Increases in conventional energy
costs– Shorter payback for savings
• Carbon reduction goals by increased perceived/actual value of green or
net-zero buildings
TRENDS?

High Performance Buildings

PHASE I: Pre-designStep #1— Organize for zero carbon emissions: Develop plan for learning and approachesStep #2—Accept design conditions: Define environmental, occupant comfort and project financial goals before beginning design. PHASE II: Design and constructionStep #3—Resolve the macro-scale: Develop site and architectural strategies that reduce energy needs and optimize energy generation.Step #4—Develop integrated solutions: Define whole building systems to “tunnel through cost barriers.”PHASE III: StewardshipStep #5—Maintain zero: Provide a plan to operate building with Net-zero emissions.

• Take advantage of climate
• Choose efficient & integrated systems
• Reduce “safety factors” in engineering design
– “belt and suspenders” approach outmoded
• Use modeling effectively• Renewables: a last
resort!
Key Elements Of Integrated Design

topography, fog, etc.
• Daylighting & natural ventilation/economizer cycle
• Ground-coupled heat pumps/geo-exchange
• Night-flush ventilation
– Adaptive thermal comfort• Radiant vs. Convective

• Ask the right question at the right time!– Do we need this building at all? – How big does it need to be? Now? In 10 years?– Can we design it for alternative uses in the future?– How does carpet & desk color influence lighting
design?– What “free energy” can we take advantage of?– How much money is available outside the building
budget?– What do the future occupants value most?– What controls can future operators manage?– How will we know if we’re successful?
