Environmental Impactof Buildings

• 65.2 total U.S. electricity consumption 1
• 30 total U.S. greenhouse gas emissions 3
• 136 million tons of construction and demolition
  waste in the U.S. (approx. 2.8 lbs/person/day) 4
  
  
• 12 of potable water in the U.S. 5
• 40 (3 billion tons annually) of raw materials
  use globally 6
  
• Commercial and residential

Indoor Air Quality

• Prereq 1 Min IAQ Performance Req
• Credit 1 CO2 Monitoring
• Credit 2 Ventilation effectiveness
• Credit 4 Low emitting materials
• Paint, glues, carpet, composite woods, etc.

20
Indoor Air Quality

• Credit 6 Systems Control
• Individual staff control, perimeter, central
• Credit 7 Thermal Comfort
• Humidity , temperature

21

Water Efficiency

• Water savings from
• Water-efficient fixtures and appliances
• Rainwater collection systems
• Toilets, irrigation
• Benefits include
• ? water bills
• ? volumes of wastewater trtmt
• ? storm water treatment

22

Health

• Factors contributing to poor IAQ
• Inadequate ventilation
• Chemical contaminants from indoor sources
• VOCs, smoke, toxics Sources building
  materials, cleaning products
  
• Chemical contaminants from outdoor sources
• Vehicle building exhausts thru vents windows
• Biological contaminants
• Bacteria, molds, pollen, viruses
• Inadequate temperature, humidity lighting

23

Health

• Healthy buildings can ? illness and costs
• Estimated annual productivity ? 30 - 150
  billion
  
• 10 - 30 ? respiratory diseases
• 20 - 50 ? building related sickness
• .5 - 5 ? office worker performance
• 17 - 43 billion annual health care savings
• 12 - 125 billion direct ? in worker productivity

24

Productivity

• Green buildings Improve
• ? worker productivity
• ? student scores
• ? retail sales
• Environmental factors affecting productivity
• Indoor air quality Climate control
• Lighting, esp. daylighting (Wal-Mart, Kansas)
• Biophilic features -- views, plants, etc.

25
School Daylighting Without With
More inviting, saves energy, better learning
26

Case Study
Herman Miller SQA Building

• 295,000 s.f. office manufacturing center
• Daylighting
• Interior plants
• Passive heating cooling
• 35,000 energy savings yrly
• Impact on productivity
• ? worker effectiveness and productivity

27
Resources

• Reuse Building Materials
• Resale stores
• 9 Habitat for Humanity Restores
• Odoms
• Recycle Ann Arbor
• Your own?

28
Life Cycle Cost

• Sustainable building features may cost more on
  the front end however
  
• Over the life of a building
• initial building cost equals 2 of total costs
• OM equals 6 of total costs
• 92 of the life cycle cost of a building are
  personnel costs
  
• Green buildings can increase worker productivity
  by 20-30!

Why Build Green?

• What could a 30-35 energy savings in your
  buildings could save ?? annually !
  
• Reduces the dependency on foreign oil!

47
Why .. (continued)

• Environmentally preferable
• Superior design and construction methods
• Integrated design
• Optimized life cycle cost
• Commissioned assured optimum operation
• Post-occupancy evaluation

48
Why? - Your Return on Investment

• Lower operating costs
• More efficient systems
• Lower life cycle ownership costs
• Design integration can lower lighting and HVAC
  loads
  
• Higher employee health and well being
• Reduced absenteeism, illness and fatigue
• Higher worker productivity and morale
• A friendlier work environment
