To reduce sound transmission between adjacent spaces, construction plans should specify
Answer(s): C
Non-hollow core doors provide better sound isolation and speech privacy than hollow core doors, which can allow sound to leak through. According to the WELL v2 standard, doors that connect two occupiable rooms and doors to mechanical equipment rooms should have a non-hollow core, minimum STC/Rw of 30 and seals at the head, jamb and base.
WELL v2 Sound Feature S03, WELL AP Candidate HandbookTo reduce sound transmission between adjacent spaces, using non-hollow core doors for private offices and conference rooms is an effective strategy. These doors, being more solid than their hollow counterparts, inherently offer better sound insulation. This characteristic helps to minimize noise leakage into and out of these spaces, thereby enhancing acoustic privacy and reducing distractions. This measure, in conjunction with other sound isolation practices, contributes to a more conducive working environment by maintaining the confidentiality of discussions and improving overall acoustic comfort.
For projects that include operable windows, which of the following outdoor air contaminants determine how window use should be managed?
Answer(s): A
According to Feature A07: Operable Windows, part 3 of the WELL Core requirements, the project team must monitor outdoor levels of ozone, PM10, temperature and humidity, and discourage occupants from opening windows when outdoor air either (i) exceeds ozone levels of 51 ppb or PM10 levels of 50 g/m³; (ii) has a temperature of 8 °C [15 °F] above or below indoor set temperature; or (iii) has a relative humidity above 60%1. PM2.5 is not explicitly mentioned in the feature, but it is a subset of PM10 and has similar health effects, so it is reasonable to assume that it should also be considered when managing window use.

A design for a WELL building has HVAC zones of 650 ft2 (60 m2) and less than 10 occupants for more than 90% of regularly occupied spaces. This design
Answer(s): D
A design with small HVAC zones and low occupant density can enhance thermal comfort by allowing users to adjust the temperature and air flow within their own zones. According to the WELL v2 standard, projects should provide user-adjustable thermostats or other controls for at least 90% of regularly occupied spaces. Ceiling fans can also improve thermal comfort by increasing air movement, but they are not required for this design.

A building operations staff and a WELL AP are developing a cleaning plan for a new office building. What is the best strategy to minimize environmental damage from the cleaning process?
According to Feature A09: Cleaning Products, part 1 of the WELL Core requirements, the project team must use cleaning products that are certified as low-hazard or safer by a qualified third party, such as Green Seal, UL ECOLOGO, or EPA Safer Choice1. This helps reduce the exposure of building occupants and cleaning staff to harmful chemicals and volatile organic compounds (VOCs) that can adversely affect indoor air quality and environmental health2.

Which of the following ergonomic design strategies would a project team implement to achieve Part1: Support Visual Ergonomics of Feature V02: Ergonomic Workstation Design?
Answer(s): B
Adjustable monitors allow users to position the screen at an optimal distance, height and angle for their visual comfort and posture. According to the WELL v2 standard, projects should provide monitors that can be adjusted in height by at least 0.1 m [4 inches], tilted between -5 and 30 degrees, and rotated between -90 and 90 degrees.
WELL v2 Ergonomic Workstation Design Feature V02, WELL AP Candidate Handbook To achieve Part 1: Support Visual Ergonomics of Feature V02: Ergonomic Workstation Design, a project team should ensure that 100% of workstations include an adjustable monitor. This requirement emphasizes the importance of user adjustability in workstations, particularly for desktop computers, to support optimal monitor height, viewing angles, and horizontal distances. Adjustable monitors or monitor stands allow individuals to customize their workstation to meet their visual comfort needs, thereby reducing eye strain, discomfort, and the risk of musculoskeletal disorders.
