What is sustainable design

1
What is sustainable design?

• Sustainable design is a holistic, integrated
  approach to building design that seeks to
• Minimize negative impact to the natural
  environment
• Optimize the quality of the indoor environment
• Optimize long-term cost of operating and
  maintaining buildings

2
Why sustainable design?

• Saves money
• Saves resources
• Increases productivity
• Reduces absenteeism
• Improves public image
• Betters the community

3
Iowa Sustainable Design Initiative

• Partnership among the Iowa Department of Natural
  Resources, the Department of Administrative
  Services, and other organizations
• Launched in 1999 to encourage the integration of
  sustainable design in statewide projects

4
What is LEED?

• A point-based green building rating system that
  measures sustainability of a building
• Developed by the U.S. Green Building Council

Iowa Laboratories Facility Overview

• Houses labs for
• University of Iowa Hygienics Des Moines
  Operations
• Iowa Department of Public Health Medical Examiner
• Iowa Department of Public Safety Division of
  Criminal Investigation
• Iowa Department of Agriculture and Land
  Stewardship

6
Lab Overview

• The first project to pursue LEED certification
  as a part of the Iowa Sustainable Design
  Initiative

7
Lab Overview - continued

• The designers, the State of Iowa, and the
  construction manager have integrated sustainable
  design principles to provide a building that
  will
• seek LEED certification
• be energy efficient
• provide a healthy, comfortable indoor environment
  for employees
• reduce waste and promote recycling
• use water more efficiently

What separates this building apart?

• Commitment to sustainable design from the start
• Involvement of building tenants from the start
• Close collaboration of design team throughout
  project
• Integration of sustainable design throughout
  project

11
Sustainable Design Components

• Site planning
• Indoor environmental quality
• Energy
• Material and resource use
• Water use

12
Site planning - What did we do?

• Aggressive effort to reduce erosion and runoff
  during construction
• Planted more than 9 acres in native vegetation

13
Site planning - continued

• Maintained topsoil on site
• Installed 40 less parking than ordinance
  required resulting in saved, less storm water,
  and less heat island effect

14
Site planning - continued

• Planned for extensive shading of non-pervious
  surfaces
• Used light-colored Energy Star compliant roofing
  material

15
Site planning - continued

• Building orientation maximized for energy
  efficiency and daylighting applications
• Dedicated space to car and van pools and bike
  riders

16
Indoor Environmental Quality - What did we do?

• Extensive air changing for high level of fresh
  air
• Non-smoking building

17
Indoor Environmental Quality- continued

• Flushed out building air during and after
  material installation
• Protected vent/ducts from construction dust and
  other air hazards

18
Indoor Environmental Quality- continued

• Used adhesives, paints, and coating with no or
  low amounts of volatile organic compounds (VOC)
• Carpet systems from Carpet and Rug Institutes
  Green Label Indoor Air Quality Test Program

19
Indoor Environmental Quality- continued

• Composite wood products with no added
  urea-formaldehyde
• ASHRAE thermal comfort standards achieved
  including humidity control

20
Energy - What did we do?

• Developed and utilized a commissioning plan to
  insure efficiencies
• Designed building to exceed ASHRAE/IESNA Standard
  90.1-1999
• Used high efficient variable frequency drives,
  energy recovery system, chiller, boilers and pumps

21
Energy - continued

• Zero use of CFC-based refrigerants in new base
  building HVAC R systems
• Reduced based estimated energy cost by at least
  20 percent

22
Energy - continued

• Extensive use of daylighting without impact
  efficiency of heating/cooling systems
• Comprehensive use of light dimming technology

23
Materials Resources - What did we do?

• Specified a minimum of 20 of building materials
  that are manufactured regionally within a radius
  of 500 miles
• Examples windows, cement, structural steel

24
Materials Resources - continued

• Post-consumer recycled content constitutes at
  least 10 of total value of project materials
• Examples metal studs, carpet tile, fly ash
• Recycled or reused at least 50 of all
  construction site waste

25
Materials Resources - continued

• Used a minimum of 50 of wood-based materials
  certified in accordance with the Forest
  Stewardship Council guideline
• Dedicated recycling area in building

26
Materials Resources - continued

• Aggregate Subbase
• Bituminous Concrete Pavement
• Concrete Reinforcement
• Masonry Accessories
• Structural Steel
