Flooring Provides Stylish Pathway to Sustainability

The design for these floors needed to convey a high-end professional feel while maintaining the benefits which had been achieved using an access floor system. The architectural firm of Mark Cavagnero Assocs. had a clear vision of materials: teak plank wood, multi-piece porcelain and carpet. The challenge became how to blend these varying materials as transitions and maintain the functionality of the access floor system. At 30-stories and 450,000 sq. ft., 350 Mission Street is the first LEED Platinum high-rise in the city. Designed with a sharp focus on sustainability—not the least being more efficient HVAC delivery—a goal that fit in well with the desire of the developer, Kilroy Realty Corp.

Vegetated Solution

Designed to give a pre-vegetated garden roof option with a fully integrated assembly the InstaGreen GT-4 Tray features a uniquely structured bottom element that provides large amounts of water storage for plant use, as well as an aeration feature that helps ensure gas exchange can occur at the bottom of the media column. This water storage area is useful where stormwater management is a consideration.

Like Sunscreen For Your Roof

Duro-Shield Coatings are formulated from 100%- elastomeric acrylic and can seal to a range of single-ply membrane materials, along with metal, wood and built-up substrates, to protect roofs from UV damage and heat build up. The coatings create a bright white finish to reflect the sun.

Cool Roof Spotlight

Colonial Seam, a new residential standing seam metal roofing panel, is a clip-less panel from Accel Roofing Products, a division of ATAS, that offers a traditional standing seam aesthetic with contemporary factory-formed advantages. It is installed by locking the one-piece panel into the previous panel and fastening through pre-punched slots, allowing for expansion and contraction. All fasteners are concealed by the adjacent panel. The positive locking action makes it virtually impossible for the panels to slide apart. Panels are available in widths of 12.375-in. and 16.375-in., with a 1-in. seam height, in 0.032 aluminum and 24 gauge metallic coated steel. Both substrates have the same PVDF

Wear a Coat

Cool roofs can be achieved by other means. Guardian elastomer-based coating options, for example, can cost-effectively transform metal, BUR, modified bitumen and aged single-ply roofs into reflective roofs that can reduce building energy requirements. Roof Guardian RG-170 is a white finish coat with a solar reflectance index (SRI) of 109. Roof Guardian RG-180 is a fibered white coating (SRI 108) that achieves Class A fire rating. Both are Energy Star and CRRC rated. The waterproofing products are formulated using an acrylic polymer base for enhanced adhesion and durability, and both resist cracking and peeling. Roof Guardian products are also useful for gutterways, repairs and other projects

Air It Out

Ventilation and airflow also have their place in effective roof systems. For example, cool roof systems incorporate a combination of tile products designed to increase air flow and ventilation under tile with materials that reflect UV heat from the roof to reduce the amount of heat transferred into the structure. This translates into fewer on/off air conditioning cycles to maintain interior temperatures. Comparative testing has shown a heat transference differential of as much as 45 degrees on the underside of roof decking when simulated solar energy is directed at the tile installations compared to like-colored asphalt shingles using the same roofing materials.

Self-Sealer

Enverge Air and Vapor Barrier (AVB) is an asphalt based, self-sealing wall barrier that provides energy savings and contributes to better air quality for building occupants. Its reduced maintenance costs are attributable to its moisture and thermal control, and self-adhered installation is available in 40-mil or 25-mil thickness.
