Each question shows the correct answer and an explanation of why it is right
Which of the following strategies can be used to achieve a point in Innovation Credit, Innovation, Option 1.Innovation?
Option 1 of the Innovation credit underLEED V5.1 BD+C rating system (Building Design and Construction) allows for achieving significant, measurable environmental performance using a strategy not addressed in the LEED green building rating system1. Implementing an employee engagement and education plan could be a unique strategy that promotes sustainability and environmental stewardship, which is not specifically addressed in the LEED rating system.

Which item is included in the reuse calculation for Materials and Resources Credit, Building Life-Cycle Impact Reduction?
The reuse calculation for MR Credit Building Life-Cycle Impact Reduction includes the surface area of structural elements that are reused in place or salvaged and reinstalled, such as floor decking, columns, beams, and roof decking. Exterior glazing and plumbing fixtures are not considered structural elements and are not included in the reuse calculation.Asbestos insulation is a hazardous material that should be removed and disposed ofproperly, not reused.Reference: MR Credit Building Life-Cycle Impact Reduction,LEED V5Reference Guide for Building Design and Construction123
What percentage of all energy usage is attributable to buildings?
According tothe U.S. Green Building Council (USGBC) and U.S. Department of Energy, buildings account forapproximately 40% of total energy consumptionin the United States.
This includeselectricity, heating, and cooling loadsacrossresidential, commercial, and industrial buildings.
Buildings are the largest energy consumers, surpassingtransportation and industry sectors.
LEED emphasizesenergy efficiencyto help reduce this40% energy demand.
Buildings account for 40% of all energy consumption, making Option C the correct answer.

An HVAC system consists of an air handler supplying conditioned air (mixture of return air and outdoor air) to an office, corridor, conference room and lobby. For Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance, the ventilation rate procedure calculations must be based upon what HVAC system configuration?
A multiple-zone system is a system that has one or more air handlers supplying conditioned air to more than one zone. A zone is a space or group of spaces within a building with heating and cooling requirements that are sufficiently similar so that desired conditions (e.g., temperature) can be maintained throughout using a single controlling device. The ventilation rate procedure calculations must be based on the multiple-zone system configuration because the HVAC system in the question serves different zones with different ventilation requirements.Reference:LEED V5Reference Guide for Building Design and Construction, p.6881; ASHRAE Standard 62.1-2010, Section 6.2.52
Increasing which of the following variables will require an increase in the outdoor airflow rate under Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance?
The outdoor airflow rate is the amount of outdoor air that is supplied to the building by the ventilation system to dilute indoor air pollutants and provide fresh air for the occupants.The outdoor airflow rate depends on the ventilation standard that the project follows, which can be either ASHRAE 62.1-2010 or CEN Standard EN 15251-20071. Both standards specify the minimum outdoor airflow rate per person and per unit area for different occupancy types and zones. Therefore, increasing the number of occupants will require an increase in the outdoor airflow rate to maintain the minimum ventilation level. The other variables, such as supply air velocity, system ventilation efficiency, and supply air temperature set point, do not directly affect the outdoor airflow rate, although they may influence the energy consumption and thermal comfort of the ventilation system.
