Overview – Build<strong>in</strong>g Simulation
Objective for this module<br />
Conv<strong>in</strong>ce you that:<br />
• Build<strong>in</strong>g <strong>simulation</strong> is fun and can add value <strong>to</strong> the<br />
design process.<br />
• To understand your <strong>simulation</strong> results, you need <strong>to</strong><br />
understand the underly<strong>in</strong>g models.

Why build<strong>in</strong>g <strong>simulation</strong>?<br />
To compare different design options dur<strong>in</strong>g design development.<br />
To reduce risk through reduced plann<strong>in</strong>g uncerta<strong>in</strong>ty.<br />
To demonstrate code compliance (absolute values).

Why build<strong>in</strong>g <strong>simulation</strong> for architects?<br />
Better <strong>in</strong>terfaces. Faster computers.<br />
To <strong>in</strong>teractively improve your design at the schematic design<br />
stage.<br />
To be able <strong>to</strong> engage <strong>in</strong> a dialogue with the HVAC eng<strong>in</strong>eer.<br />
Competitive edge: high demand for <strong>simulation</strong>ists<br />
Opportunity <strong>to</strong> work on more <strong>in</strong>terest<strong>in</strong>g projects.<br />
Caveat: You have <strong>to</strong> understand the underly<strong>in</strong>g assumptions.
