Question
By specifying the installation of occupancy sensors for the building’s lighting system, what pair of LEED credit categories would be affected?
A. Innovation and Water Efficiency
B. Integrative Process and Sustainable Sites
C. Location and Transportation and Materials and Resources
D. Indoor Environmental Quality and Energy and Atmosphere
Answer
D. Indoor Environmental Quality and Energy and Atmosphere
Explanation
Occupancy sensors are devices that detect the presence or absence of people in a space and automatically turn the lights on or off accordingly. By installing occupancy sensors for thebuilding’s lighting system, projects can achieve two benefits: improving the indoor environmental quality (IEQ) and reducing the energy consumption.
Occupancy sensors can enhance the IEQ by providing lighting control for individual spaces, allowing occupants to adjust the light levels to their preferences and needs. Occupancy sensors can also save energy by avoiding unnecessary lighting when spaces are unoccupied, thus lowering the electricity demand and greenhouse gas emissions.
Installing occupancy sensors in a building’s lighting system primarily affects two LEED credit categories: Indoor Environmental Quality (IEQ) and Energy and Atmosphere (EA).
Indoor Environmental Quality (IEQ) credits focus on creating a comfortable and healthy indoor environment for building occupants. Occupancy sensors contribute to IEQ by automatically adjusting lighting levels based on the presence or absence of people in a space. This feature helps to maintain appropriate illumination levels, reduce glare, and minimize unnecessary light pollution, all of which contribute to a more pleasant and productive indoor environment.
Energy and Atmosphere (EA) credits aim to reduce energy consumption and promote the use of renewable energy sources. Occupancy sensors play a crucial role in optimizing energy efficiency by ensuring that lights are only on when needed. By automatically turning off lights in unoccupied areas, occupancy sensors help to minimize energy waste and reduce the building’s overall energy consumption. This, in turn, leads to lower energy costs and a smaller carbon footprint.
The other credit categories mentioned in the options are not directly related to the installation of occupancy sensors:
- Innovation credits recognize exceptional performance or innovative strategies that go beyond the requirements of existing LEED credits.
- Water Efficiency credits focus on reducing water consumption and promoting the efficient use of water resources.
- Integrative Process credits encourage a holistic approach to building design and construction, considering the interconnectedness of various systems and stakeholders.
- Sustainable Sites credits address the environmental impact of site selection, development, and management practices.
- Location and Transportation credits promote the selection of sites with access to public transportation, walkable neighborhoods, and reduced parking footprint.
- Materials and Resources credits encourage the use of sustainable materials, waste reduction, and responsible sourcing practices.
In summary, installing occupancy sensors for a building’s lighting system primarily impacts the Indoor Environmental Quality (IEQ) and Energy and Atmosphere (EA) credit categories in the LEED rating system.
