Attachment A Recommendations for reduction of suspected biological growth on surfaces are: • Removal of all existing ductwork from the attic space, A/C units in attic to remain in place or abandoned. Remove all ceiling A/C grills with moisture resistant gypsum board where duct system penetrations are removed. • Replacement of attic access panels with insulated access panels. • Adjust the soffit height around the counter area to a height of approximately 8 feet from the floor. (The current soffit is 24" and is recommended to be cut down to 8" from the ceiling level.) Remove all visible mold drywall and replace in bar area and high moisture areas identified in Wood report. • Install adequate exhaust in the restroom areas. • Increase the insulation value in the attic space to R-38 • Provide baffles at the eave line to restrict insulation from blocking the exterior soffit ventilation space. • Replace the soffit ventilation opening registers with a screened unit having greater than 40 percent free area. • Repaint/replace drywall in bathrooms affected by visible growth with an epoxy -based paint. 2. Recommendations for reducing the moisture in the front wood wall under the window unit: • Provide a continuous layer of insulation on the outside of the wood framing below the window unit, sealed to the vapor barrier. Replace T -III with new beveled hardiboard siding. • Provide a moisture/vapor impermeable cover, likely metal or fiberglass, to the assembly below the window unit and seal the cover to the masonry. Recommendations for other areas to help with moisture intrusion: • Provide a moisture/vapor barrier between the wood and masonry units. • Provide a moisture/vapor barrier between the window unit and the wood perimeter frame. • Rest doors and weather stripping to provide an effective weather seal. • Provide a stoned maintenance area adjacent to the wall surfaces with the bottom of the stone being below the bottom of the interior slab elevation. This will allow for proper drainage and run off from the roof and condensing units. Recommend this to be approximately 12" deep and a minimum of four feet from the wall edge out. 4. Additional recommendations for HVAC system not previously mentioned above include: • HVAC equipment replacement — Provide new PTAC units in lieu of the ductless split systems currently used. Remove wall units. PTAC units shall provide outdoor air into the system (the unit would install under the front window of the room and is a self-contained u n it). • Replace windows in all villa rooms with new impact rated, single -hung windows.
