  3. 3. Building Envelope and Louver Design DemandsData Center Design is evolving rapidly as these highlyspecialized facilities exert ever increasing demands on powerand cooling needs.+ =Building Envelope requirements often also exceed typicalassemblies addressing basis of design parameters of: Security Water Intrusion - Weather Tightness Breach of Envelope - Storm or Blast Threat Increased Air Supply to Mitigate Internal Heat Prepared for Slideshare by Jon Salis - Specification Sales Manager (940) 445-1845 [email protected] For Design Assistance Contact: Jon SalisConstruction Specialties Inc - (940) 445-1845 [email protected]
  4. 4. Increased Air Supply to Mitigate Internal HeatThese highly specialized facilities exert ever increasingdemands on power and internal cooling needs.= +Design Trends in Data Center see what was once demand needsof 25 Watts PSF soaring to 500 Watts PSF and rising.In response to this increased internal heat potential more air supplyfor cooling is required and that supplied air should be controlled forwater intrusion that can be harmful to the sensitive equipment thatresides in these structures.Due Diligence and Thoughtful Selection for all Design Parameters!

  5. 5. Louver Design BasicsDesign Challenges in Louver SelectionBefore you can begin to make the appropriate Louver Selectionfor a Data Center Project lets familiarize our selves with the 3basic categories of Architectural Wall Louvers and subsequenttest methods in place by AMCA (Air Movement and ControlAssociation) for rating and certifying Louver Performance.

  9. 9. Louver Design - Wind Driven Rain Louvers3- Basic Louver Categories Non-Drainable Blade Conventional Louvers Drainable Blade Conventional Louvers Wind Driven Rain Rated LouversA Wind Driven Louver typically consists of acomplex blade profile with multiple integral guttersto the Louver Blade which directs water to channelsin the jambs that downspouts the water down andout at the sill. Blade profiles are designed to spin theincoming air twice to cast off airborne water. Can be Sight Proof Good Free Area Moderate to Low Pressure Drop AMCA Tested to 500 L 99 - Wind Driven Rain-WaterPenetration - Forced Air/Rain TestWind Driven Rain Louvers represent the currenttechnology in keeping water out of buildings.
