RPG effusor Newsletter - November 2009

RPG Continually Evolving
The RPG monthly effusor Newsletter introduces new products and services and highlights recent projects. If you are receiving this Newsletter for the first time, here is a link to all previous issues online.






RPG is committed to the goals of the USGBC and we invite you to visit us at the PCD Engineering Booth 5239 from November 11-13th in Pheonix, AZ. At RPG we manufacture fire-rated, sound diffusing and absorbing products in compliance with LEED guidlines. We will also feature our new Noise and Vibration system.

In this issue we feature health care facilities using our popular Topakustik absorptive wood system. Sinai Hospital Atrium useds our Topakustik panel system and Northwest Hospital Center Expansion uses our tongue and groove Topakustik plank system.

Sinai Hospital Atrium
This atrium was part of an 87,000 square foot addition to the hospital that was a green building expansion. The highlight of the expansion project was the 8,000 square foot atrium that is a large common area providing lots of natural light, vegetation and a water feature. It is a peaceful environment for patients, visitors and staff. Two adjacent walls of this atrium are covered with Topakustik Panels to help control the sound level in the space. The Topakustik panels are a 13/3 M pattern in American Cherry and are trimmed with a metal reveal between each panel. RPG provided both grooved and ungrooved panels on this project. Architect: Hord Coplan Macht – Baltimore, MD

Northwest Hospital Center Expansion
RPG was involved in providing materials for the new Outpatient Registration area and the Herman & Walter Samuelson Breast Care Center. In both cases the Topakustik material was used around registration stations, check-in areas, and waiting room areas. The addition of acoustical materials in these spaces allow for more speech privacy as well as lower reverberant levels for a more pleasant environment. These areas used Topakustik tongue and groove planks on the wall in an American Cherry finish as well as 2x2 concealed grid lay-in tiles in a floating cloud application also in an American Cherry finish. Architect: Hord Coplan Macht – Baltimore, MD

Boston Medical Center
RPG has provided Topakustik Tiles for the Moakley Building of the Boston Medical Center. This is a cancer care center that provides access to state-of-the-art services and clinical research. The building was an addition of 134,000 square feet to the hospital and shares a common entry concourse with the entry lobbies of Boston Medical Center. The RPG materials are located in the waiting room area and corridor and are successful in providing a quiet acoustical environment in these spaces. The project utilizes Topakustik Panels in a 2x2 lay-in grid in a 12/4 pattern and an American Cherry finish. There were plain panels also provided by RPG in this project to keep finish and veneer matching consistent. Architect: Tsoi/Kobus & Associates – Cambridge, MA

We invite you to view our project gallery to see how RPG products can be used in your next design. Take a Look


CATT
We continue to offer assistance with the most comprehensive acoustic modeling and auralization package, CATT-Acoustic v8.x. and provide absorption and scattering modeling coefficients in CATT and EASE formats. New pricing effective 11/1/2007. Prediction and Auralization modules each $3,000. We can help facilitate the building and prediction of your models.

Education
Please join us for our Diffuse Seminars. Dates to be announced. You can view the Agenda pdfs on line. We also invite you to visit our Acoustics Library, Diffuse Reflections, Diffuse Bulletins and Competitive Evaluations.

Test Data
RPG is offering random and directional incidence diffusion, scattering and absorption coefficients for all of its products. Random and directional incidence diffusion coefficients and polar patterns (shown below) indicate the uniformity of diffusion and can be used in CSI specifications and as a metric to compare potential diffusing surfaces. The random incidence absorption coefficient can be used in CSI specifications as a metric of absorption efficiency. The directional and random incidence scattering coefficients can be used in computer modeling programs, but not as a metric of diffusion uniformity.

RPG Rapid Prototyping
RPG offers Rapid Prototyping Service.

This allow us to fabricate and test scale models of new scattering surfaces that the acoustician or architect may envision using in a project. This is the future.
