An Analysis of Simulation Tools at an Interdisciplinary FirmPaul Kempton and Meredith Elbaum

• Who are we?• How are we using simulation tools today?• How do we envision using simulation tools

in the future?

What we hope to answer…

What are we looking for?

• Tools that tell us the impact of our design decisions

• Daylighting• Energy Performance• Ventilation• Embodied energy/LCA

• Area of Glazing• R-values• Orientation• Shading devices

How are we using it?

•Sun Path Diagram•Shadow Study

•What is the period of time the landscape is in shadow?

•Several platforms used for different modeling purposes

•Model influenced the scale of space between buildings


•Daylighting•Shadow Study•Glare Detection

•What are the approximate daylight levels in the atrium?

•Model influenced the scale and location of the designed shading device

•Not all quantitative values were yielded from the use of this software


•Daylighting•Shadow Study•Glare Detection

•How is daylight effected by changing the orientation of the skylights?

•Radiosity Sketch

•False Color Images identifying glare quantity and locations

•Not all quantitative values were yielded from the use of this software


•Climate Data•Human Comfort

•A method of displaying the local climate

Air Leakage, Average 2story office building Northern US1.3 cfm/sfNISTIR 7238, June 2005

Air Leakage, Target0.24 cfm/sf

The target is achieved through implementation of continuous air barrier between outside and inside conditioned space, combined with good construction methods.
