Lighting Control (1 point) For at least 90% of individual occupant spaces, provide individual lighting controls that enable occupants to adjust the lighting to suit their individual tasks and preferences, with at least three lighting levels or scenes (on, off, midlevel). Midlevel is 30% to 70% of the maximum illumination level (not including daylight contributions). For all shared multioccupant spaces, meet all of the following requirements. ·· Have in place multizone control systems that enable occupants to adjust the lighting to meet group needs and preferences, with at least three lighting levels or scenes (on, off, midlevel). ·· Lighting for any presentation or projection wall must be separately controlled. ·· Switches or manual controls must be located in the same space as the controlled luminaires. A person operating the controls must have a direct line of sight to the controlled luminaires. EQ credit interior lighting - option 2 - Lighting Quality - correct answer Option 2. Lighting Quality (1 point) Choose four of the following strategies. A. For all regularly occupied spaces, use light fixtures with a luminance of less than 2,500 cd/m2 between 45 and 90 degrees from nadir. Exceptions include wallwash fixtures properly aimed at walls, as specified by manufacturer's data, indirect uplighting fixtures, provided there is no view down into these uplights from a regularly occupied space above, and any other specific applications (i.e. adjustable fixtures). B. For the entire project, use light sources with a CRI of 80 or higher. Exceptions include lamps or fixtures specifically designed to provide colored lighting for effect, site lighting, or other special use. C. For at least 75% of the total connected lighting load, use light sources that have a rated life (or L70 for LED sources) of at least 24,000 hours (at 3-hour per start, if applicable). D. Use direct-only overhead lighting for 25% or less of the total connected lighting load for all regularly occupied spaces. E.

For at least 75% of the regularly occupied floor area, meet a ratio of averag - correct answer Specifying low-emitting products and materials will improve indoor air quality, increase the effectiveness of a flush-out, and increase the likelihood of passing the air quality tests. For projects that pursue Option 1 under Construction IAQ management credit - Proper attention to contaminants during construction will improve overall indoor air quality, increase the effectiveness of a flush-out, and increase the likelihood of passing the air quality tests.

View factors should be more than 3 Multiple lines of sight to vision glazing must be 90 degrees apart A hotel project decides to do air-testing to achieve EQ Credit IAQ Assessment. Which of the following must be true in order for the project to earn the credit? - correct answer For offices, retail, schools, hospitality, and multifamily residential projects, test areas no larger than 5,000 square feet (465 square meters). The test should be done in breathign zone - 3 and 6 feet . The test should be done during normal occupied hours Other scenarios For warehouses or large open spaces in other building types (e.g., ballrooms in hospitality, gymnasiums in schools), a limit of 50,000 square feet (4 654 square meters) may be used. If there is evidence that the air in the space is well mixed and sources of contaminants of concern are uniform, project teams may test a single location in that space. A healthcare project with mechanical ventilation is implementing interior cross-contamination prevention, filtration and adding an entry way system. Which of the following must a healthcare project do in addition to the entryway systems to earn EA Credit Enhanced Indoor Air Quality Strategies using Option 1. Enhanced IAQ Strategies? - correct answer For healthcare projects - In addition to the entryway system, provide pressurized entryway vestibules at high-volume building entrances. Option c - only applies to projects with natural ventilation or mixed mode. In our question it says the project is mechanically ventilated. A school project is located within one-half mile (800 meters) from a busy highway. Which of the following must be true for the project t earn LEED certification? - correct answer School project at least one-half mile (800 meters) from any significant noise source (e.g., aircraft overflights, highways, trains, industry) are exempt. During construction, a project team prepares a plan to perform building flush-out to achieve EQ Credit IAQ Assessment. Due to some delays, the construction schedule gets extended. Which of the following could the project do if they run out of time to complete a flush-out? - correct answer Since in this case, they run out of time to complete a flush-out - project could pursue Option 2 which can typically be completed in less time than a flush-out, but the cost of air quality testing must be factored into the project budget (another possible question) What is true of projects located in EPA Radon Zone 1? - correct answer If the project building contains residential units, each dwelling unit must meet all of the following requirements. ·· Unvented combustion appliances (e.g., decorative logs) are not allowed. ·· Carbon monoxide monitors must be installed on each floor of each unit. ·· All indoor fireplaces and woodstoves must have solid glass enclosures or doors that seal when closed. ·· Any indoor fireplaces and woodstoves that are not closed combustion or power-vented must pass a backdraft potential test to ensure that depressurization of the combustion appliance zone is less than 5 Pa. ·· Space- and water-heating equipment that involves combustion must be designed and installed with closed combustion (i.e., sealed supply air and exhaust ducting) or with power-vented exhaust, or located in a detached utility building or open-air facility. ·· For projects in high-risk areas for radon, EPA Radon Zone 1 (or local equivalent for projects outside the U.S.), design and construct any dwelling unit on levels one through four above grade with radon-resistant construction techniques. Follow the techniques prescribed in EPA Building Radon Out; NFPA 5000, Chapter 49; International Residential Code, Appendix F; CABO, Appendix F; ASTM E1465; or a local equivalent, whichever is most stringent (possible quesiton). A project design with mechanical ventilation should use which of the following filtration to earn EQ Credit Enhanced IAQ Strategies? - correct answer For EQ Credit Enhanced IAQ Strategies, Each ventilation system that supplies outdoor air to occupied spaces must have particle filters or air-cleaning devices that meet one of the following filtration media requirements: ·· minimum efficiency reporting value (MERV) of 13 or higher, in accordance with ASHRAE Standard 52.2-2007; or ·· Class F7 or higher as defined by CEN Standard EN 779-2002, Particulate Air Filters for General Ventilation, Determination of the Filtration Performance.

Which of the following are acceptable glare control devises for EQ Credit Daylight?(Choose 3) - correct answer Acceptable glare-control devices include interior window blinds, shades, curtains, movable exterior louvers, movable screens, and movable awnings. All glare-control devices must be operable by the building's occupants to address unpredicted glare. Automatic devices with user override are acceptable. Diffused and translucent glazing systems do not require glare-control devices. The HVAC contractor for a small office project is planning to perform flush-out construction ends and the building has been completely cleaned in order for the project to earn EQ Credit Indoor Air Quality Assessment. Which of the following actions he must take If occupancy is desired before the flush-out is completed? - correct answer For option 1 flush-out - if occupancy is desired before the flush-out is completed, the space may be occupied only after delivery of a minimum of 3,500 cubic feet of outdoor air per square foot (1 066 260 liters per second of outdoor air per square meter) of gross floor area while maintaining an internal temperature of at least 60°F (15°C) and no higher than 80°F (27°C) and relative humidity no higher than 60% (another possible question).
