Design Intent and Sustainability Principles
The intent of this credit is to design buildings for low-waste operations. Reducing per capita waste is an important component of the Harvard University Sustainability Principles. The first principle states that "institutional practices that promote sustainability, including measures to increase efficiency... and to decrease production of waste and hazardous materials, both in Harvard’s own operations and in those of its suppliers." Harvard's buildings should have appropriate space dedicated to the collection and temporary storage of recyclables, so that it is as easy as possible for occupants to recycle.
During OFS waste audits, students collect data from trash that can then be utilized by staff to monitor and report on continuous improvement in reducing Harvard's waste.
Financial Considerations
Recycling is required by law in Cambridge. Including space for recycling early in the project process will avert any additional cost due to last-minute changes.

Design Intent and Sustainability Principles
The intent of this credit is to reduce waste, reduce fossil fuels burned in transit, and reduce material consumption. The first of the six Harvard University Sustainability Principles is a commitment to continuous improvement in “institutional practices that promote sustainability, including measures to increase efficiency and use of renewable resources, and to decrease production of waste and hazardous materials, both in Harvard’s own operations and in those of its suppliers." The sixth sustainability principle states that Harvard commits to “establishing indicators for sustainability that will enable monitoring reporting and continuous improvement." The documentation required from the contractor to divert waste from disposal is one method for the university to monitor progress. See Institution Recycling Network's Construction Waste Management Comparison chart for Harvard projects.
Financial Considerations
Effective July 1, 2006, Massachusetts implemented a Waste Ban on disposal, incineration, or transfer for disposal at solid waste disposal facilities for asphalt pavement, brick, concrete, and metal. The ban also prohibits wood disposal or transfer for disposal at landfills. These materials must be recycled. The King County, Washington, Construction Recycling Program website provides a calculator to determine recycling costs. John Gundling of Institution Recycling Network calculated the cost of recycling versus disposal for a project at Radcliffe, and found recycling to be less expensive.
Some contractors are concerned that costs increase as workers sort waste. Lessons from a Harvard internship in C&D waste from summer 2002 are that the key is to not work longer, but to work smarter. It takes 73 minutes as opposed to 78 minutes to dump off-cuts from gypsum board as opposed to stacking it and dollying it to a dumpster for recycling. The salvaged, clean gypsum can be used to make acoustic ceiling tiles.

A key lesson on diverting construction and demolition waste from landfills is to begin early in coordinating with any possible donor recipients in order to identify suitable building parts. In addition, the scheduling is crucial; deconstruction crew members need to be able to complete their work before a wrecking crew arrives on site.

Design Intent and Sustainability Principles
The intent of this credit is to encourage the reuse of building materials through salvage or refurbishment. Reusing resources reduces the extraction of materials from virgin resources, saves landfill space and saves money.
Financial Considerations
Using salvaged materials saves the cost of purchasing new materials. However, The Davis Langdon study points out that most projects are not able to achieve the materials reuse credit "because there is not enough opportunity for use of salvaged, refurbished or reused materials, products or furnishings to meet the 5 percent of 10 percent thresholds" (Matthiessen, Fay and Morris, 18).

Design Intent and Sustainability Principles
Purchasing recycled-content materials supports sustainability through the creation of an end market for materials that would otherwise be sent to the landfill and reduces the use of virgin materials. Recycled-content materials decrease production of waste in the operations of Harvard’s suppliers, one of the first goals of Harvard University Sustainability Principles. Measuring the recycled content of building materials is “one indicator for sustainability that will enable monitoring reporting and continuous improvement," tenets of the sixth sustainability principle.
Financial Considerations

Design Intent and Sustainability Principles
The purchase of locally manufactured building materials supports the local economy, which aligns with the fourth Harvard University Sustainability Principle to support long-term economic, environmental and socially responsible decision-making.
In order to enable comparative analysis of sustainability implications, life cycle analysis of building materials is necessary. In addition to the local economic benefits of the use of locally extracted and manufactured building materials, less overall embodied energy, and therefore less overall energy, is spent due to shorter distances traveled in transport of these materials. The intent of selecting regional materials is that it stimulates the local economy and decreases the overall amount of energy used to transport building materials to the site.
Financial Considerations
The Davis Langdon study found that "with the modifications made to this requirement under LEED 2.2, which added the requirement for local extraction as well as local manufacture, this credit became very difficult to achieve." Therefore it is difficult to assess what the cost implications may be (Matthiessen, Fay and Morris, 18). For the full cite, see Financial Links. The study Green Value suggests that locally sourced materials can have a significant positive impact on the economy of the local community (Green Value. Royal Institute of Chartered Surveyors, October 2005).

Design Intent and Sustainability Principles
The intent of this credit is to select and incorporate rapidly renewable materials into the building and site design in order to encourage the development of those markets and to promote efficiency in the production of the building materials. The first of the Harvard University Sustainability Principles states that the university is committed to continuous improvement in "demonstrating institutional practices that promote sustainability, including measures to increase efficiency and use of renewable resources...both in Harvard’s own operations and in those of its suppliers." In order to "support long-term economic, environmental and socially responsible decision-making," the university is committed to continuous improvement in developing planning tools such as life cycle analysis for different materials. Initial research shows that rapidly renewable materials are environmentally preferable because of their low-embodied energy and their low toxicity.
Financial Considerations
The Davis Langdon study found that, previously, the cost for compliance to these credits was significant, even though some rapidly renewable materials could be incorporated into the project at low cost. The high percentage threshold made it difficult to identify enough materials to meet it. LEED 2.2 has lowered the threshold, making this credit more achievable (Matthiessen, Fay and Morris, 19). For the full cite, see Financial Links.

Design Intent and Sustainability Principles
The intent of this credit is to specify and utilize wood certified by the Forest Stewardship Council (FSC) for structure, framing, rough carpentry and finish carpentry. The use of FSC certified wood promotes the long term health and productivity of forests. The goal of the first Harvard University Sustainability Principle is to "demonstrate institutional practices that promote sustainability, including measures to increase efficiency and use of renewable resources, and to decrease production of waste ... both in Harvard’s own operations and in those of its suppliers." By specifying FSC certified wood, the university encourages its suppliers to provide sustainable products, thereby influencing the marketplace.
Financial Considerations
FSC certified wood costs 0-15% more than non-certified wood.
