I have model of an 8 story 30,000 sqm office building; it has…

64 core rooms

11 non-core rooms

14 ceiling plenums

808 apertures

42 shades

Does 2 hours for an energy simulation seem correct or super long. Notes below…

HB MODEL TO OSM method

11:40 begin

12:00 solar calculations initializing

1:00 calculation of heat

really slow on periods

cancelled after 2+ hours

;;;;;

HB ANNUAL LOADS method

takes about 5 minutes

;;;;;

(restructured code to run rooms, glazing and shades parallel into HB MODEL component instead of in series into HB MODEL component)

HB ANNUAL LOADS method

2:10 begin

2:15 done

;;;;;

HB MODEL TO OSM method

2:17 begin

2:20 solar calculation initializing

hung up on calculating sky diffuse exterior solar reflection factors

2:40

these 7x each

Beam-to-Diffuse Exterior Solar Reflection Factors

Beam-to-Beam Exterior Solar Reflection Factors

warming up

2:47 Sizing Period #1

2:51 Sizing Period #2

2:54 Sizing Period #3

up to Sizing Period #7?

3:35 Starting simulation at 01/01/2006 for run Period 1, looks like its monthly…

4:15 done!
