EQ Credit 4.1: Low Emitting Materials,
Adhesives and Sealants

Intent: Reduce the quality of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well being of installers and building occupants.

Requirement: All adhesives and sealants used on the interior of the building shall comply with the requirements of the referenced standard.

EQ Credit 4.2: Low Emitting Materials, Paint and Coatings

Intent: Reduce the quality of indoor air contaminants that are odorous, irritating and/or harmful
to the comfort and well being of installers and building occupants.

Requirement: All adhesives and sealants used on the interior of the building shall comply with the requirements of the referenced standard.

EQ Credit 7.1: Thermal Comfort Design

Intent: Provide a comfortable thermal environment that supports the productivity and well being of building occupants.

Requirement: Design HVAC systems and the buildings envelop to meet the requirements of the referenced standard.

The ANSI/ASHRAE Standard 55-2004, Thermal Environmental Conditions for Human Occupancy, addresses several facets of temperatures inside buildings. This standard addresses temperature, thermal radiation, humidity and air speed, along with personal factors such as activity and clothing. Specifications include combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space.

EQ Credit 7.2: Thermal Comfort

Intent: Prove an assessment of a buildings thermal comfort within a period of six to 18 months after occupancy.

Requirement: Implement a thermal comfort survey of building occupants. The survey should collect anonymous responses about thermal comfort in the building including an assessment of overall satisfaction with thermal performance and identification of thermal comfort related problems. Building owners must agree to develop a corrective plan of action if survey results indicate that more then 20% if occupants are dissatisfied with the thermal comfort of the building. This plan should include measurement of relevant environmental variables in problem areas in accordance with the referenced standard.

EA Credit 1: Optimize Energy Performance

Intent: Achieve increasing levels of energy performance above the baseline in the prerequisite standard to reduce environmental and economic impacts associated with excess energy use.

Requirement: Option 1–Whole Building Energy Simulation-Demonstrate a percentage improvement in the buildings performance rating compared to the baseline building performance rating standard. The minimum energy cost savings is 14% for which 2 LEED points are earned.

Efficient use of energy is a requirement for new construction, under LEED Energy Optimization Credit EA 1, and Certi-Shine polished concrete can contribute to this end by reducing the amount of energy needed to light, heat and cool buildings.

MR Credit 1.1/1.2: Building Reuse

Intent: Extend the life cycle of existing building stock, conserve resources, retain cultural resources, reduce waste and reduces environmental impacts of new buildings as they relate to materials manufacturing and transport.

Requirement: Maintain at least 75% & 95%, based on surface area, of existing building structure, and envelope, including structural floor and roof decking. By considering the reuse of an existing building verses building new structures, project teams can earn LEED points when the surface area to be retained is at least 75% concrete or more during a major renovation.

MR Credit 1.3: Building Reuse

Intent: Extend the life cycle of existing building stock, conserve resources, retain cultural resources, reduce waste and reduces environmental impacts of new buildings as they relate to materials manufacturing and transport.

Requirement: Use existing interior non-structural elements, such as flooring in at least 50% of the completed building.

MR Credit 2.1/2.2: Construction Waste Management

Intent: Divert construction and demolition debris from disposal in landfills and incinerators. Redirect recyclable recovered resources back to the manufacturing process. Redirect reusable materials to appropriate sites.

Requirement: Recycle and/or salvage at least 50%/75% of non hazardous construction and demolition debris. Develop and implement a construction waste management plan that, at a minimum, identifies the materials to be diverted from disposal and whether the materials will be sorted on-site or co-mingled. Calculations can be done by weight or volume, but must be consistent throughout.

MR Credit 3.1/3.2: Materials Reuse

Intent: Reuse materials and products in order to reduce demand for virgin materials and to reduce waste, thereby reducing impacts associated with the extraction and processing of virgin resources.

Requirement: Use salvaged, refurbished or reused materials such that the sum of these materials constitutes at least 5% and 10% respectively, based on cost, of the total value of materials on the project. (You can only include permanently installed materials).

A project team needs to calculate the total cost of all materials used on the project and determine the material "replacement value" of comparable concrete material. The total cost of these materials and other salvaged, refurbished or reused materials must be a minimum of 5% to earn one point and 10% to earn an additional point. (Note: Project teams that do not qualify for this credit may qualify for points under MR credit 2.1 or 2.2)

MR Credit 4.1/4.2: Recycled Content

Intent: Increase demand for building products that incorporate recycled content materials, thereby reducing impacts resulting from extraction and processing of virgin materials.

Requirement: Use materials with recycled content such that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (based on cost) of the total value of the materials in the project.

The recycled content value of a material assembly shall be determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value.

Mechanical, electrical and plumbing components and specialty items such as elevators shall not be included in this calculation. Only include materials permanently installed in the project. Furniture may be included, providing it is included consistently in MR Credits 3-7.

Recycled content shall be defined in accordance with the International Organization for Standardization document, ISO 14021 –environmental labels and declarations - Self-declared environmental claims (Type II environmental labeling).

Post-Consumer Material is defined as waste material generated by households or by commercial, industrial and institutional facilities in their role as end-users of the product, which can no longer be used for its intended purpose.

Pre-consumer Material is defined as material diverted from the waste stream during the manufacture process. Excluded is reutilization of materials such as rework, regrind or scrap generated in a process and capable of being reclaimed within the same process that generated it.

MR Credit 5.1/5.2: Regional Materials

Intent: Increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environment impacts resulting from transportation.

Requirement: Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% (based on cost) of the total material value. If only a fraction of a product or material is extracted/harvested/recovered and manufactured locally, then only that percentage (by weight) shall contribute to the regional value.

Mechanical, electrical and plumbing components and specialty items such as elevators and equipment shall not be included in this calculation. Only include materials permanently installed in the project. Furniture may be included, providing it is included consistently in MR Credits 3-7.

ID Credit 1: Innovations in Design

Intent: To provide teams and projects the opportunity to be awarded points for exceptional performance above the requirements set by the LEED for New Construction Green Building Rating System and/or innovative performance in Green building categories not specifically addressed by this Rating System.

Requirement: In writing, identifying the intent of the proposed innovation credit, the proposed requirement for compliance, the proposed submittals to demonstrate compliance, and the design approach (strategies) that might be used to meet the requirements.
