Ramping up Energy Efficiency in Buildings Using Building Codes

Ramping up Energy Efficiency in Buildings- Using
Building Codes

• How the
• 2009 International
• Energy Conservation Code
• is developed, adopted and implemented
• to achieve building energy efficiency

Great Energy Efficiency Day- 2009
2
Objective

• Identify the 3 steps involved in getting from the
  concept of higher energy efficiency, to buildings
  that actually use less energy strong code,
  adoption, enforcement.
• Briefly describe the adoption process, and the
  importance of training and enforcement.
• How the stimulus will jump start adoption and
  enforcement.

Mandatory Provisions Such as

Chapter 4 Residential Efficiency

• Significant Changes
• Improved window and skylight
• efficiency for Climate Zones 1-4
• Improved basement / crawl wall insulation across
  all climate zones
• Building air tightness must be demonstrated
  through testing or rigorous inspections
• An air-barrier and insulation checklist is
  codified
• Wood fireplaces required to have gasketed doors
  and must draw combustion air from the outside

Chapter 4 Residential Efficiency

• Significant Changes cont
• Programmable (set-back) thermostats
• required
• All duct systems outside of the building
• required to be tested for leak tightness
• New criteria for duct system testing provided
• A minimum of 50 of lamps in permanent fixtures
  are to be high efficiency lamps
• Provisions for snow and ice-melt controls added
• New energy conservation requirements for pools.

Chapter 5 Commercial Efficiency

• Significant Changes
• Scoping choice Meet either the commercial
  provisions of the IECC or ASHRAE Standard
  90.1-2007
• Insulation/window tables now contain separate
  requirements for high-rise condos and
  apartments
• Improved insulation efficiency Climate Zones 7

• Radiant heating required for unenclosed spaces
• Indicates when/where a Demand Control Ventilation
  strategy is required and
• Fan motor energy use and HP limitations improved.

2009 IECC vs. 2006 version

• Brings more energy efficiency gains than in
  history of IECC
• Gains set for new and renovated IECC-compliant
  homes
• From 12.2 to 14.7 or more, improvement over
  2006 IECC
• 2009 ICF International study, commissioned by
  Energy Efficient Codes Coalition
• Homes built to the 2009 IECC will consume less
  energy
• U.S. families living in 2009 IECC homes will save
  money
• Average of 235/ year
• Energy savings and cost savings vary by climate
  zone, from 9.5 to about 15

What can code compliance do?

• If the 2006 IECC was adopted and applied in all
  50 states, the country could save up to 6.6
  quadrillion BTUs of energy over the next twenty
  years, while eliminating more than 100 million
  metric tons of carbon equivalent emissions. EPA
  Building Code Fact Sheet
• By 2030, DOE estimates that full adoption and
  implementation of 30 model codes in America's
  homes and buildings has the potential to save
  approximately 2.7 Quads of energy per year and to
  avoid nearly 160 million metric tons of C02
  equivalents per year, which could potentially
  save consumers up to 20 billion in annual energy
  expenditures. DOE Asst. Sec David Rodgers,
  testimony 7/08

Scope

• The IECC applies to
• Residential Buildings
• One- and Two-family dwellings, Townhomes (not-IRC
  buildings)
• Multifamily dwellings three-stories or less in
  height
• Commercial Buildings
• Multifamily dwellings four stories or greater in
  height
• Eight global climate zones and three moisture
  regimes
• Compliance assessment choices
• Prescriptive criteria- for ease of enforcement
• Simulated Performance criteria- for design
  flexibility

International Energy Conservation CodeIECC-
adoption and enforcement

• National Model Energy Code of Choice
• - 40 States and D.C.
• Cited throughout federal law for
• National private and Federal housing initiatives
• Energy Independence Security Act of 2007 (EISA)
• Energy Conservation Production Act, as amended
• National benchmark for single family homes and
  townhomes
• National benchmark for low-rise condominiums and
  apartments
• Manufactured Housing (HUD 24 CFR 3280)
• Energy Efficient Mortgage Programs (FHA, VA,
  Fannie Freddie)

Once the 2009 IECC is adopted

• How is that translated into energy-efficient new
  and renovated buildings?
• Train architects, builders, engineers,
  contractors, subcontractors, others in the
  construction industry
• Train planning and permitting officials, and
  building inspectors in the content of the code,
  and methods of inspecting and testing for
  compliance.
• Both groups have a head start, because both were
  involved in the development process, and both are
  familiar with the structure, language and
  application of the IECC.
• IECC fully coordinated with IRC, IBC and other
  I-codes

15
How does the stimulus bill help?

• The stimulus bill contains language requiring a
  plan to adopt the 2009 IECC or better-residential/
  2007 ASHRAE 90.1 or better-commercial.
• Condition for qualifying for 3.1 billion in
  State Energy Program funds
• Stimulus also funds EISA Block Grants, which has
  specific language authorizing grants to develop,
  implement and adopt and enforce, building codes

16
Reaching full compliance

• Stimulus requires both a plan for active training
  an enforcement, and annual measurement of percent
  compliance to reach 90 by 2017.
• Much of the technology, construction methods,
  test methods, and some of the products are new,
  and both builders and contractors and code
  officials will need training to achieve full
  compliance.
• The stimulus requires a plan, and provides funds.
