Actual Example of Cost Savings of 61% with Keidel Software's DrainStar Siphonic Calculator

    OBERWESER, GERMANY, June 11, 2009 /24-7PressRelease/ -- Siphonic drainage design really can be simple. Because siphonic system pipework is specifically dimensioned and assembled, the challenge in the past has been to accurately calculate pipe dimensions based on the particular layout of the drainage system. The DrainStar Siphonic Calculator is custom-designed for each roof drain and pipe manufacturer with all of the products and materials needed. With just a few entries from the builder-owner or designer, the software precisely calculates costs, as well as providing complete parts lists and producing detailed isometric drawings.

"The clear graphical presentation allows for easy editing and handling of projects, and enables the user to run pipe network calculations very quickly." Says Jürgen Frei, General Manager of Wavin, a Keidel customer. Adds Hans George Aufmhoff, an engineer, "In a nutshell, the DrainStar Syphonic Calculator is a reliable tool that is key to boosting functional and economic efficiency in flat roof drainage technology."

Our current economic climate demands that we take a harder look at costs. Construction costs are dramatically cut, when builder-owners choose siphonic drainage over conventional gravity-based solutions. As market leaders in Germany and with a presence on several continents, Keidel Software has experienced that their customers can easily save 61% of predicted costs by switching from conventional roof drainage to siphonic.

"Builders everywhere can achieve a comparable strong cost savings, no matter the size of the project," explains Rolf Keidel, founder of Keidel Software. "The big obstacle in the past to using siphonic drainage was that the calculations were so complicated. This is no longer a problem when you use the DrainStar Siphonic Calculator."

In addition DrainStar users can benefit by following the example of Maxflow, a Keidel customer, that achieved certification of their products and Keidel's DrainStar as a siphonic system through the British Board of Agreement (BBA).

Following is an real-life example of how a cost savings of 61% can be achieved on a 700 m2 roof surface by switching from conventional drainage to siphonic drainage.

The dimensioning of the gravity roof drainage is based on DIN 1986-100, Table A4. KEIDEL Software's DrainStar Siphonic Calculator was used for the dimensioning of the SRD piping. The calculation is based on VDI 3808.

PEHD pipes were chosen for the two systems. Electrofusion coupler sleeves were used for connections. For a simpler comparison, fastening material was not included. We have used customary German gross prices in the price base comparison, but any local prices will result in substantial cost savings. Installation cost was not included. The cost of wages worldwide is so disparate that we've left it out to avoid distorting the cost comparison. The drains are one-piece special outlets without accessories for the stated intended purpose.

Cost estimates were prepared automatically with the DrainStar Siphonic Calculator software. Other DrainStar solutions also offer comparisons that result in greater detail, including parts lists, costs lists and detailed specifications that go from drainage and fastening materials down to the screws to be used. Additional details about Keidel Software are in the appendix.

Keidel Software currently has representative offices in Asia, Europe and the United States. The Cost Savings flyer is now available for download (http://www.keidel-software.com ) on the Keidel Software website.
