Sustainable design seeks to create structures that require fewer natural resources to build, maintain and adapt to future uses. Key strategies include choosing quality, lasting materials and creating flexible, multi-functional spaces.

Why build for sustainability? Sustainable design offers valuable benefits that are good for owners, occupants and the environment:

• More efficient use of resources for building construction, operation and maintenance.
  
  
• Healthier and more-productive environments within the structure.
  
  
• Better protection of the land at the building site and where raw materials are extracted, manufactured and disposed.

To build sustainably, building professionals must choose materials, construction details and technologies that, in addition to achieving functional and design objectives, provide environmental advantages. In ceiling design, these benefits may be achieved in four key areas:

Material selection. Sustainable ceiling products typically contain a high level of recycled content such as synthetic mineral wool and recycled paper, and recycled metal in suspension systems. Non-recycled ingredients should be renewable, such as binders made of agricultural starches instead of petroleum-based chemicals. And, manufacturing processes should be fuel-efficient and minimize waste.

Indoor environmental quality. Environments designed for comfort and functionality are likely to meet occupant needs long into the future without extensive upgrades or renovations. Ceilings with no or very low formaldehyde and antimicrobial protection can reduce risk of VOC exposure and mold growth. Ceiling panels with high light reflectance can minimize eyestrain (a cause of fatigue) and help conserve energy and cut operating costs by achieving optimal light levels with fewer fixtures and lower-wattage bulbs.

Material performance. Ceiling panels designed to resist wear and abuse are likely to have a longer life cycle, reducing consumption of additional resources for maintenance and repairs.

Sustainable practices. In renovation projects, participating in a ceilings recycling program can divert significant waste from landfills and reduce reliance on natural resources extracted from the land.

Consumers have become increasingly aware of the need to conserve energy, manage raw materials, reduce waste and safeguard against pollutants. In response, many developers and owners now demand buildings that will help save energy, preserve the integrity of surrounding land and assure a clean, healthy indoor environment.

By employing sustainable design, building professionals are taking a broader view than ever before, recognizing that smart decisions at the design stage create structures that will require fewer natural resources throughout their useful lives to remain comfortable, productive and efficient.
