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.References: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.

This credit has exemplary performance because it allows projects to earn an additional point by reducing outdoor water use by 75% or more from the calculated baseline1.The credit requires projects to reduce outdoor water use by at least 50% from the calculated baseline, which is determined by the EPA WaterSense Water Budget Tool2. The credit encourages projects to use native or adapted plants, efficient irrigation systems, alternative water sources, or no irrigation at all.

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.References: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 .

The Simple Payback Period is the time it takes for an investment to pay for itself through savings. To calculate the Simple Payback Period, divide the initial investment by the annual savings. In this case, $1,500.00 USD divided by $500.00 equals 3. To find the exact payback period, consider the rate of return. With a 33% rate of return, the actual savings per year would be $500.00 plus 33% of $500.00, which equals $665.00. Dividing the initial investment of $1,500.00 by $665.00 gives a payback period of approximately 2.26 years, which is closest to two years.

• The concept of Simple Payback Period is a fundamental financial calculation discussed in the LEED AP O+M documentation. It is part of evaluating the cost-effectiveness of energy and water efficiency improvements, particularly under the Energyand Atmosphere and Water Efficiency categories. This metric is commonly used in sustainability projects to assess the viability of efficiency upgrades.
