Further cavity wall performance benefits include: - Improved HVAC system performance - Lower MEP systems first costs and lower MEP optimization costs - Increased daylighting and better comfort and acoustics in interior spaces Inside, a system of translucent and opaque screens focuses light down a 27-story atrium, defining a glowing room that is the hallmark of the hotel experience. Glass balconies, placed periodically within the cavity, provide a desirable amenity to upgraded rooms. The project also includes a small retail component and an innovative housing form, characterized by skip stop access, thru block units and operable sunshades that provide privacy and solar control.
