Morsels, scraps, broth, aroma
◊ Building envelope, α, ε, shading, massing, elevators
◊ Lighting (6–7 connected W/m 2 , ~1–3 W/m 2 when
occupied, lights-off when only machines are present)
◊ What temperature and humidity range does the
equipment actually require? (e.g,. most modern networking
eqt is designed for 20–80%, so 30–70%
makes reasonable allowance for sensor errors, etc.;
but some data centers strive for 50±5%)
◊ Load diversity, thermal time constants
◊ Dynamic time/space matching of cooling to actual
instantaneous needs (JCI, HP)
◊ Perhaps innovative fluid-handling devices
◊ Lots of little savings multiply: e.g., 0.9 10 = 0.35
