Design IX – Technology Environmental Systems V …and Now for something Completely Boring! • • The Systems Checklist HVAC Basics Using a “Basis of Design” Conceptual Quantification
Design IX – Technology Environmental Systems V Power The “Checklist” Water Misc. • Supply point? • Transformer? • Inside vs. Outside • Emergency Power? • Distribution Panels • Supply (well, city, tank) • Treatment? • Metering? • Inside vs. Outside • Sprinklers? • Fire Pump? • Hot Water? • Wastewater? • Elevations? • Storm Water? • • Telephones? Internet? CATV? Security? Public Address? Central Clock? Lightning Protection? • Multi-Media • Med-gases • Nurse alarm, etc.
Design IX – Technology Environmental Systems V HVAC Checklist – The Basics 1. Will building be conditioned? {heated, cooled} 2. Heat type? {radiation, forced air, passive air} 3. Heat source? {electricity, gas, oil, solar, geothermal} 4. Distribution? {water, air, none (self-contained)} 5. Cooling type? {radiation, forced air, passive air}
Design IX – Technology Environmental Systems V Air Systems 1. Air units? {large central, multiple mid-size, many local} 2. Air balanced? {supply, return, outside air, exhaust, pressure} 3. Air ducts? {exposed, concealed – do they fit? } Water Systems 1. Water units (radiators)? {floor, wall, ceiling}
Design IX – Technology Environmental Systems V Heat 1. Water source? {boiler, solar, heat pump} 2. Component locations? {boiler room, roof panels} 3. Utility requirements? {electricity, gas, oil} Cooling 1. Water source? {chiller, heat pump - location} 2. Chiller System? {air cooled, water cooled location}
Design IX – Technology Environmental Systems V Basis of Design - Systems
Design IX – Technology Environmental Systems V How big is that Duct? • 1 CFM (cubic feet per minute) per SF of space • 1000 FPM (feet per minute) of air velocity
Design IX – Technology Environmental Systems V Example • 10, 000 SF floor area served by (1) AHU system • 1 cfm x 10, 000 sf / 1, 000 fpm = 10 SF of duct area • Don’t forget supply…AND…. return air • 20 SF = 24” high by 120” wide, or
Design IX – Technology Environmental Systems V System Components / Spaces • Cooling Towers = 10’ to 20’ tall • Air Handling Units = 8’ to 35’ long (4’ – 10’ wide) • Main Switchgear = 10’ – 20’ long • Fire Pump rooms = 10’ x 15’ • IT Rooms = 10’ x 15’ • Electric Closets = 8’ x 10’
