Overview

• Why Zero Net Energy?
• Policy landscape is changing
• The Zero Energy Commercial Buildings Initiative

Buildings Use the Most Energy, and Commercial
Growth Rate gt Residential

The Policy Landscape is Changing

• Architecture2030 Challenge (Mayors support)
• ASHRAE Std 90.1, Std 189, Advanced Guidelines
• California AB 32 Strategic Plan
• Path to Zero via incentives and codes
• Energy Independence Security Act (EISA)
• Federal goals existing and new buildings
• Federal green leasing
• Zero Net Energy Commercial Buildings Initiative
• ZEB new buildings by 2030
• ZEB building stock by 2050

Approaching a Zero Energy Future

• The best way to predict the future is to invent
  it.
• Alan Kay
• If I had asked people what they wanted, they
  would have said faster horses."
• Henry Ford
• Lets Define a Future Vision that
• is ambitious, and gives us what
• we need, not necessarily what
• is easily achievable!

8
Key Findings

• Large Savings Potentials but
• Fragmented, risk averse industry
• Short time horizons
• Benchmarking disclosure are still rare
• Beyond retrofit
• New construction
• Renovation
• Equipment turnover
• Operations (continuous commissioning)

9
Strategy Sector-, Region-, Climate-specific

• Continuum of effort
• Research ? Innovate ? Demonstrate ? Deploy ?
  Mandate
• Workforce skills and training
• Think long-term, act now
• Capture first 20-30 of savings
• Demonstrate what it takes to get 50 soon
• Research systems solutions to get 70 savings
• Make performance visible and understandable
• Cant manage what you cant measure
• Assess, evaluate, act Learn by doing
• What works ? Verify and deploy
• What doesnt ? Fix and deploy
• Facility owner/operator/supplier perspectives
