Lecture Overview • Linking Architects to Systems • Communicating Conceptual Understanding • The Checklist • Basic Sizing Tricks • Results – “Insipid to Inspired”
Architects use Light as an Aesthetic • Boardwalk Hall, Atlantic City, NJ
…its also an Engineering System • Bloomberg Financial, Princeton, NJ
Human Perception is an Aesthetic Goal • Sight • Sound • Touch • Smell • Taste • Sense of Safety • Sense of Comfort • Sense of Functionality
Perception is Quantifiable • Convection – 40% • Radiation – 40% • Evaporation – 20% • Conduction - <1% • Air Motion • Net Radiation • Relative Humidity • Air Temperature
…and thus an Engineering System • Stale • Stuffy • Fine • Drafty • Windy Warmer Air Cooler Air Stale Windy
Conceptual Understanding • Layperson’s View • Engineer’s View • Diagrams as a Tool • Diagrams as a Sales Pitch
Diagrams Illustrate Choices • Illuminate the Building….or • ….Highlight a lighting effect
Building Incoming Water Diagram CW Main runs in 1st Floor Ceiling Plenum Need Bsmt Room for Pump, etc.
Building Leaving Water Diagram Need thick walls for Sanitary stacks
…a Vignette on Hot/Humid Sustainable Design • Delicate Energy Balancing • Ventilation Breezes • Use of Shade • Thermal Flywheeling
Sustainable System for Hot – Humid Region • Reduce penetration of radiation • Remove inside heat • Enhance evaporation • Increase air motion
…and Now for something Completely Boring! • The Systems Checklist • HVAC Basics • Using a “Basis of Design” • Conceptual Quantification
The “Checklist” Power 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.
HVAC Checklist – The Basics • Will building be conditioned? {heated, cooled} • Heat type? {radiation, forced air, passive air} • Heat source? {electricity, gas, oil, solar, geothermal} • Distribution? {water, air, none (self-contained)} • Cooling type? {radiation, forced air, passive air} • Cooling source? {electricity, gas/oil, evaporation, geothermal} • Distribution? {water, air, DX, none (self-contained)}
Air Systems • Air units? {large central, multiple mid-size, many local} • Air balanced? {supply, return, outside air, exhaust, pressure} • Air ducts? {exposed, concealed – do they fit?} Water Systems • Water units (radiators)? {floor, wall, ceiling}
Heat • Water source? {boiler, solar, heat pump} • Component locations? {boiler room, roof panels} • Utility requirements? {electricity, gas, oil} Cooling • Water source? {chiller, heat pump - location} • Chiller System? {air cooled, water cooled - location} • DX? {compressor/condenser locations}
How big is that Duct? • 1 CFM (cubic feet per minute) per SF of space • 1000 FPM (feet per minute) of air velocity
Example • 10,000 SF floor area served by (1) AHU system • 1cfm x 10,000sf / 1,000fpm = 10 SF of duct area • Don’t forget supply…AND….return air • 20 SF = 24” high by 120” wide, or 36x84, etc.
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’
The Results • Systems have a “natural” or “normal” mode • Systems can be aesthetically challenging • Architect’s who understand systems …win! • Don’t let systems steamroll your Aesthetic • Understanding leads to accommodation • Accommodation leads to Aesthetic Control
Industry made into Art • Rhythm • Order • Scale • Module • Layered
