Introducing Sustainable Building Technology by REHAU

Fri, 23 Mar 2012 21:26:48 GMT

Sustainable Comfort

Whether touring a fine art exhibit at a world-famous museum or watching a favorite television program at home, a comfortable indoor environment can make a significant difference in how we enjoy these experiences. Buildings that surround us with consistent warmth, refreshing coolness, low humidity and filtered air offer an ideal setting for year-round indoor comfort.

Few of us would demand comfor at any cost. We want sustainable comfort - comfort that's affordable, easy to maintain and good for the environment. Not only do we expect our buildings to make efficient use of energy; we also are beginning to require our buildings to sustain themselves with energy from the earth, wind and sun. Whether the goal is to lower a buildings carbon footprint or achieve complete independence from the power grid, sustainable building technology from REHAU can make a substantial contribution.

REHAU innovations have helped define the world of construction for more than 60 years. From geothermal heat exchange to radiant heating and cooling to residential fire protection, our systems are working to provide sustainable comfort in thousands of residential and commercial buildings around the world.

ASHRAE Study of Typical Inlet Conditions to Ceiling Diffusers Performance Data

ASHRAE has approved and funded a study of inlet conditons in ceiling diffusers and the effects that ducted inlets have on ceiling diffuser performance data. This study in being conducted at the University of Las Vegas Nevada (UNLV - Nevada) as ASHRAE study RP1335 by Dr. Brian Landberger and Dr. Doug Reynolds. Titus's Senior Chief Engineer, Leon Kloostra, is one of the principal authors for this study.

The majority of manufacturer catalog performance data for diffusers is developed following ASHRAE Standard 70, where an inlet to the duffuser is installed under ideal conditions. This standard requires uniform airflow entering the diffuser adn assumes that no inlet balancing device is in the diffuser inlet. Inlet conditons to the diffusers can greatly affect the diffuser performance, but the magnitude due to these conditions is not known.

RenewAire Energy Recovery Unit Products Overview

Mon, 09 Mar 2009 15:11:55 GMT

For over 35 years RenewAire has been the innovator and leader in energy efficient ventilation. In RenewAire ERV's. stale room air is exhausted and fresh outdoor air is brought back into the building. These two air streams are directed through a highly developed "air-to-air" energy exchange core. The air streams are physically separated by many layers of "plates" so there is no mixing or contamination of the fresh air. The plates are made of an engineered "resin" material that simultaneously transfers heat by conduction and humidity by attracting and "wicking" water vapor from on air stream to the other. This product has less maintenance than an energy wheel since there are no moving parts.

During the Air Conditioning Season

When you need to cool for comfort do you hate the stuffy, musty aire quality in your home? RenewAire ERV's provide necessary fresh air while pre-cooling and pre-dehumidifying this air with energy that would otherwise be lost with the exhaust air. With summertime himidity control (latent energy) being the largest portion of air conditioning cost, RenewAire's humidity transfer is critical. In fact RenewAire is typically three times more energy efficient than products that transfer only heat.

During the Heating Season

Outdoor air is warmed close to room temperature with heat that would otherwise be lost with the exhaust air. The water vapor transfer moderates extremes in humidity levels which helps prevent moisture damage or over-drying of the home. The heat and humidity transfer (sensible and latent) gives RenewAire a big advantage over other air-to-air exchangers typically recovering 30% more energy in winter.

Wind-Driven Rain Louvers are the Best Defense Against Water

Tue, 29 Apr 2008 21:03:22 GMT

AMCA’s Inmotion magazine supplements highlight important industry issues and key solutions to today’s HVAC problems. In the Spring 2007 issue, Ruskin’s Louver Product Marketing Manager, James Livingston, tackles the issue of louver water penetration head-on with his article titled The Value of Wind Driven Rain Resistant Louvers. The best defense against water penetration inside a building is with the design and use of wind-driven rain (WDR) louvers.

AMCA rewrote test standard 500-L to measure the effectiveness of the louver’s water repulsion system using wind-driven rain louvers. This new test standard was based on successful designs utilized in Europe.

Mr. Livingston presumes the following. “In the last decade, there have been design innovations that enable louvers to provide greater airflow capacity and increased resistance to weather infiltration. One of the most significant improvements in this regard has been the development of wind driven rain resistant louvers. These louvers are highly effective at keeping rain out of buildings, and in many cases have significantly higher airflow capacities than traditional louvers.”

Also in the article, you’ll discover…

The importance of blade design in WDR louvers.
How WDR louvers exceed 1250 fpm performance.
What Class "A" AMCA certification rating means for WDR louvers.
How to reduce your louver opening size dramatically with WDR louvers.
