Performing a Proper Site AnalysisBetter yet consider:• Site• Climate• Program

A passively heated, cooled, and lighted building fights global warming.

Why isn’t this good enough?

Good enough?

Consider Climate

Temperature range plots

Monthly Average Hourly Temperature vs. Relative Humidity

Plot:Monthly Average High/Low Dry Bulb Temperature vs. Relative Humidity on the Bioclimatic Chart.

Links climate to design strategies!

Look at it several ways

Consider Hourly Data as Well

Find out which way the wind blows…

During the whole year…

And for selected months

June here

Where would windows go for max cross-ventilation?

Later you can draw wind flows on your site.

To show effects of vegetation, topography, & buildings.

The Plan is not the site!

You can use CoveTool or Sketch-Up to do shading studies

Or On Site:

Plot solar obstructions

On the appropriate sun chart for your assigned city.

Explore the site.

Look for microclimates.Your body is a sensor!

Make sure there is a flat place on the site model for your sun peg if you intend to manipulate the model by hand…

…or, use the heliodon tilt table with your site model and sun peg.

Record the seasonal sun/shade patterns on the site at important times of day.

Here 9am, noon, & 3pm in Jan. and Jul.

Combine and score the effects of sun and wind with hatch pattern or color code.
