In order for an occupant survey to improve the triple bottom line of a project, what should occur after the survey results have been assessed? |
Corrective action should be taken to address any problems. Surveys should be followed with analysis and corrective action if necessary.
In LEED, occupant surveys are required for some credits. However, merely doing a survey doesn't earn the credit - action must be taken on the survey results. The facility manager is usually responsible for performing corrective actions. |

|
|
A company is designing an open office plan for seventy-five employees working in an entire floor of a building. Daylighting will be used to provide natural light and reduce energy costs. To ensure effective lighting quality for all of the occupants, the design should include which of the following? |
Zoned daylighting controls Because the plan is for an entire floor of a building, different areas of the project will receive different levels of lighting throughout the day. To make sure all occupants have quality lighting, a zoned system that adjusts lighting levels based on the quantity of daylight coming in will work best. |
|
|
A building owner has concerns about the costs of increasing the ventilation from the minimum required for indoor air quality. Which of the following could help offset the operating costs? |
Using demand control ventilation Demand-control ventilation is based on monitoring spaces and only increasing the ventilation when set points are reached. This is based on having CO2 sensors/monitors in the room. For example, if a room has five people in it and then ten more come in, the CO2 in the air would go up. The sensor would register this and increase the airflow. If the ventilation is only increased as needed, the operating costs go down instead of the system running at a maximum at all times. |
|
|
A project team is trying to maximize the number of points they can achieve for their LEED project by identifying synergies. Which elements, when combined, would best achieve this goal? |
Daylight sensors Occupancy sensors Occupant lighting controls

The colors of the surfaces The types of furnishings |
|
|
What are the best design strategies for improving indoor air quality during operations and maintenance of a building? |
Increase the ventilation in the building Additional outdoor air can be provided in the building. This is a common trade-off though - when increasing the ventilation for a mechanical system the energy use of the building goes up.
Use air filters with high Minimum Efficiency Reporting Value (MERV) ratings Minimum Efficiency Reporting Value (MERV) ratings are a standard comparison of the efficiency of an air filter. The MERV scale ranges from 1 (least efficient) to 16 (most efficient), and measures a filter's ability remove particles from 3 to 10 microns in size. The ratings were developed by ASHRAE. |
|
|
A building owner and general contractor are creating a construction plan to improve the air quality during the construction process. What should the plan address? |
Keep dust and dirt out of the building, protect materials from moisture damage, flush-out the building before occupancy Housekeeping during the construction process keeps dust and dirt from collecting in the building and it's installed systems. |
|
|
When conducting a confidential occupant survey to rate the lighting, acoustics, temperature, and cleanliness of a building, who is primarily responsible for reviewing the results and taking any corrective action? |
The facility manager(s) The facility manager is the primary person responsible for the survey and its follow-up corrective action. That is not to say the other choices would not be involved - just to a lesser degree.
NOT the owner. |
|
|
Proper ventilation systems remove which of the following contaminants? |
Radon
CO2 concentrations
Material off-gassing
NOT: CFCs CFCs are part of refrigerant management. Ventilation doesn't remove them.
here are many contaminants a ventilation system should remove. Radon, VOCs from material off-gassing and CO2 levels are some of them. |
|
|
What product for an entryway system allows for good indoor air quality and is a good material choice? |
Low VOC rubber mat LEED entryways should be grills, grates, or mats to help clean people's shoes off as they walk in. This keeps dust/dirt/contaminants out. |
|
|
Which of the following elements should be considered to facilitate communication in school classrooms? |
A Soft surfaces Architectural finishes that include soft surfaces improve acoustics. Fabric-covered walls or acoustic tiles are some examples. B Duct insulation Air flowing through the HVAC system can make loud whistling and whooshing noises. Duct insulation reduces the noise of the air flow. C Building geometry The geometry of the space is critical to good acoustics. Consider a concert hall - are the acoustics good or bad? Probably good because of the effort put into the geometry of the space. There are designs that improve acoustics (like a concert hall) and designs that make for poor acoustics (such as high ceilings in a classroom)

A tenant of an office space wants an open office layout. What is one trade-off of this decision? |
The acoustics may be poor. A trade-off with the open office layout is in a large, open space the acoustics are usually poor. |
|
|
When thinking about room layouts early in the design process, which of the following should be considered? |
Acoustics Acoustics are often overlooked, but they should be considered early in the design process when designing room layouts in order to select a room design that aids this element.
I chose this which was wrong because: Entryway systems Entryway systems are part of the design of linking the outside to the inside of the building, not room layouts. |
|
|

Adjustable air diffusers Adjustable air diffusers help with ventilation control. |
|
|
A project design with a focus on creating a healthy building includes materials with low VOC emissions, grates used in the entryway, higher-rated MERV filters, and air intakes located in an open-air parking garage. Which of these design strategies negatively impacts good indoor-air quality? |
The location of the air intakes Air intakes should be located near fresh air sources and away from exhaust or smoking areas. |
|
|
Why would a project team use low-emitting materials? |
These materials protect the health of construction personnel and building occupants. Low-emitting should bring low VOC to mind. |
|
|
Designing a building with a natural ventilation system will impact what credit categories? |
Energy and Atmosphere A natural ventilation system (aka passive ventilation) will reduce the energy demands of a building. No mechanical cooling system will need to installed and run.
Indoor Environmental Quality A natural ventilation system impacts the indoor air quality of a building. Indoor air quality is part of this credit category. |
|
|
How can a project team in a hot climate reduce a building's energy use and increase daylighting? |
By installing appropriately sized and located windows Installing windows that are appropriate for the climate and that are strategically located is the correct choice. This refers back to the integrative process and discussing the best options. |
|
|
When would a project team need to consider increasing the ventilation levels to improve indoor air quality? |
Pre-design Increasing ventilation may require a bigger ventilation system. It may also consume more energy to run the system. By the time the building is being constructed, these decisions can be too late. |
|
|
Which of the following should a green cleaning policy include? |
Standards for selecting products and technologies and certification of cleaning equipment A green cleaning policy should include:
I chose this, which was wrong because: The replacement of Minimum Efficiency Reporting Value (MERV) filters and the selection of low VOC materials, furniture, and finishes Replacing MERV filters is part of operations and maintenance to improve air quality. |
|
|
Including task lighting and increasing ventilation levels in a new building has what effect on the triple bottom line? |

Capping the ducts to mechanical systems
Making sure someone is sweeping periodically to control dust
|
|
|
Changing the building envelope from single-pane glazing to double-pane glazing would result in which of the following? |
Decreased energy demand The design of the building envelope (including the glazing) impacts the energy demand of the building. While more glazing (windows) increases daylighting, the heat gain from allowing more light in may increase HVAC loads. Double-pane glazing is a better insulator than single-pane glazing. |
|
|
What amount of time do people in the United States spend on average indoors? |
The importance of the Indoor Environmental Quality (IEQ) category is partly due to how much time people spend indoors. How healthy the indoor environment is, such as air quality, is related to human health. |
