The easiest way to earn this credit is through decreasing your project’s impervious area by reducing the building footprint, increasing landscaped areas, and disconnecting impervious areas—designing sidewalks, roofs, and parking areas so that the runoff is not directed to a drainage system or other hardscapes.
For residential applications, adopting a no-smoking policy in Homeowners Association policies has been a good strategy for reducing ETS transfer between units.
For Core and Shell projects, tenant guidelines should stipulate a non-smoking policy or extra care should be taken by the core and shell build-out to ensure interior designated smoking areas will be property sealed for future tenant uses.
Establish the smoking policies for interior spaces and exterior spaces, including balconies, by working with the building owner. Many municipal codes do not permit smoking in public buildings, so banning smoking (Option 1) may be the only legal option in some cases.
There may be upfront modeling fees for CFD modeling. However, CFD can help design a better natural ventilation system that will deliver short-term payback and long-term savings.
Early air flow modeling will help the team create the most effective ventilation design. This data can inform the team on space planning and building envelope design, among other things.
Use Computational Fluid Dynamics (CFD) modeling to determine the proper sizes for windows and openings and ensure proper air movement through interior spaces. Some energy modeling programs also have CFD analysis capabilities.
Review the air-flow modeling methodology and requirements in Volume A of the CIBSE Guide and ASHRAE 62.1-2007, Section 6.2. This section of ASHRAE 62.1 offers the modeling protocol for simulating air movement within the building. It is not difficult to follow and may be familiar to modeling consultant.
