An organization pursuing LEED O+M certification for their headquarters has a renovation policy that includes strict requirements around the selection of building products and requires contractors working in the building to develop a plan for the diversion of waste produced during renovation projects. What must the organization add to their renovation policy to meet the requirements of Materials and Resources Prerequisite, Facility Maintenance and

Renovation Policy?

Correct Answer: B
Explanation

To meet the requirements of the Materials and Resources Prerequisite for Facility Maintenance and Renovation Policy, an organization must include provisions to protect indoor air quality during renovation activities. This includes implementing dust control measures, ensuring proper ventilation, and minimizing the release of pollutants. These requirements are essential for protecting the health and safety of building occupants during renovation projects. Reference: The Materials and Resources section of the LEED O+M Reference Guide discusses the components of a comprehensive Facility Maintenance and Renovation Policy, including the importance of safeguarding air quality during construction and renovation activities.

What must the project team do in order to maximize the reduction in operational costs with regard to Sustainable Sites Credit, Site Improvement Plan?

Correct Answer: A
Explanation

Reducing lawn areas can significantly impact operational costs related to landscaping maintenance, irrigation, and the potential need for chemical fertilizers and pesticides. By minimizing lawn areas and potentially replacing them with native or adapted vegetation, the site improvement plan can contribute to lower operational costs, water conservation, and improved site sustainability. Reference: This strategy is supported by the Sustainable Sites category in the LEED O+M Reference Guide, which encourages practices that reduce the environmental impact of landscaping and site management.

The development of a five-year plan under Sustainable Sites Credit, Site Improvement Plan contributes to the achievement of

Correct Answer: D
Explanation

The development of a five-year plan under the Sustainable Sites Credit, Site Improvement Plan, contributes to the achievement of Sustainable Sites Credit, Site Management, and Water Efficiency Credit, Outdoor Water Use Reduction. This plan is designed to guide site improvements that enhance sustainability and reduce water use over time.


The development of a five-year plan under the Sustainable Sites Credit, Site Improvement Plan, contributes significantly to the achievement of Sustainable Sites Credit, Site Management, and Water Efficiency Credit, Outdoor Water Use Reduction. This plan involves strategies for site improvement that include managing the site in a sustainable manner and reducing outdoor water use through efficient landscaping and irrigation practices. The plan's long-term perspective ensures ongoing commitment to sustainability and water efficiency, which are key components of LEED certification.

Reference: This approach is supported by the LEED AP Operations + Maintenance reference guide, where the importance of a comprehensive site improvement plan is discussed. The guide outlines how such a plan integrates with other LEED credits, reinforcing the interconnectedness of various sustainability strategies within the LEED framework.

A 1,500 ft2 (139 m2) mobile home is built in the downtown area of a major city. 90% of the project's gross floor will be

completed by the time of occupancy. LEED certification is being sought. Which rating system would be the most

appropriate one to use?

Correct Answer: C
Explanation

For a mobile home, especially one built in a major city, the most appropriate LEED rating system to use would be LEED for Homes. This is because ASHRAE 90.1 and associated LEED rating systems typically exclude low-rise residential buildings, which include single-family houses, multifamily structures of three stories or fewer above grade, and manufactured houses (modular or mobile homes). Since the mobile home in question falls under the category of manufactured houses, it would be more fitting to pursue LEED for Homes certification, which is designed to cater to residential projects. Reference: Information derived from the ASHRAE 90.1-2013 User's Manual indicates the exclusion of low-rise residential buildings, including manufactured houses, from the standard's scope .
