Information about green building at the Double Eagle II Airport.
Why Build Green?
The impact of America’s built environment is substantial. Buildings consume 70% of the country’s overall annual electricity use according to the U.S. Department of Energy. The U.S. Geological Service states that buildings consume 12% of all potable water, nearly 15 trillion gallons yearly. The Worldwatch Institute estimates that buildings use 40% of raw materials globally. The Environmental Protection Agency estimates that 136 million tons of construction-related waste is generated in a single year. In addition, numerous health and productive issues can be attributed to poor indoor environmental quality for building occupants.
The United States Green Building Council was founded in 1993 as a non-profit, consensus based committee organization with a mission to transform the building industry into sustainability. The USGBC’s core purpose is to transform the way buildings and communities are designed, built and operated, enabling a socially responsible, healthy and prosperous environment that improves the quality of life. The USGBC is also the administrator of the Leadership in Energy and Environmental Design (LEED) Rating System, which started in 1999.
The Leadership in Energy and Environmental Design (LEED) Rating System was developed as a format for benchmarking what can be constituted as “green building”. LEED addresses sustainable design criteria under six main categories: (1) sustainable sites, (2) water efficiency, (3) energy and atmosphere, (4) materials and resources, (5) indoor environmental quality, and (6) innovation in design.
SSc4.2: Alternative Transportation for Bikes – Double Eagle has provided a bike rack and showering facility giving occupants an opportunity to commute to work via bike.
SSc4.3/4.4: Alternative Transportation for Low Emitting and Fuel Efficient Vehicles, Parking Capacity
Double Eagle has set aside preferred parking for low emitting and fuel efficient vehicles and for carpool with the intent of promoting conscientious transportation to this facility and reduce the carbon footprint of building occupants.
SSc5.1 & 5.2 Protect or Restore Habitat/Open Space
Double Eagle has set aside land as open space and vegetated the land with native vegetation. This in turn, helps reduce the need for water as this native vegetation already responds to the typical waterfall in it’s native landscape.
|SSc6.1/6.2: Stormwater Design – This project reduces water pollution by reducing the contaminants leaving the site and removing pollutants from stormwater runoff. All stormwater leaving the Double Eagle site will flow through 4 major retention ponds that allow the water to be naturally treated and stored to avoid unhealthy runoff to streams in large storm events.|
In the United States, approximately 340 billion gallons of fresh water are withdrawn per day from rivers, streams and reservoirs. Strategies implemented at `1900 Sixteenth Street reduce the amount of water consumed daily.
WEc1: Water Efficiency
The landscape design of native vegetation includes mainly drought tolerant plants and will not require the use of potable water.
WEc3: Water Use Reduction
Use of dual-flush toilets, low flow urinals, and aerators on faucets contributes to an overall water savings of 38% over the standard water fixtures used in a similar building per ASHRAE 90.1-2004
Energy and Atmosphere
EAc4: Enhanced Refrigerant Management
Ozone (O3), a naturally-formed gas, is an atmospheric layer that regulates UV radiation that reached Earth from the sun. Chloroflorocarbons (CFCs) release chlorine atoms near the ozone and convert them to O2, reducing the ozone later. Double Eagle uses no CFCs and reduce other harmful ozone depleting compounds in all refrigeration used in the cooling equipment for the buildings heating, ventilation, air conditioning and refrigeration systems.
EAc6: Green Power
Double Eagle will purchase 35% (or 70% for an ID credit depending on owner decision) green power. This green power purchase encouraged the development and use of grid-source renewable energy technologies.
Materials and Resources
MRc2: Construction Waste Management Over 50% OR 75% of the construction waste from Double Eagle was diverted from the landfill and recycled. This in
cludes scrap metal, plastics, paper, cardboard, and other building materials.
MRc4: Recycled Content
Over 20% of the building materials used to build Double Eagle were made of post-consumer o post-industrial recycled content reducing the impact resulting from extraction and processing of virgin materials.
MRc5: Local and Regional Materials
Over 20% of building materials used on Double Eagle were extracted, processed, and manufactured regionally within 500 miles of the site. This supports local economies and encourages the use of indigenous resources reducing environmental impacts from transportation.
Indoor Environmental Quality:
EQc4: Low Emitting Materials
Odorous, irritating and harmful air contaminants have been reduced in the building by using low volatile organic compounds for all adhesives, sealants, paint, and coatings and utilizing only green label plus carpet and composite wood free of urea-formaldehyde. The reduction of these harmful contaminants creates a healthy environment for occupants.
EQc8.1 and 8.2: Views for 90% of Spaces
Core and shell building design is such that tenants will have views from 90% of spaces and over 50% of the spaces are daylight to a ambient level equal to typical fixtures
Green Cleaning Program
Double Eagle will implement a green cleaning program that utilizes strategies to reduce harmful chemical infiltration through cleaning creating a healthier environment for both cleaning crews and occupants.
