Lethbridge Herald (Newspaper) - March 23, 1973, Lethbridge, Alberta 26 - THE LETHBRIDGE HERALD - Friday, March 23, 1973 High buildings affect winds Bv GLENN IS ZILM OTTAWA (CP) - Have you ever stood at the corner of a high-rise building with almost gale-force winds whistling about your ears, thinking winds never used to be this strong? You're probably right, but don't blame the weather, blame the high-rise developer, says Neil Stamlen, an engineer and research officer in the aeronautical section of the National Research Council. He and Dr. R. L. Wardlaw. head of that section, are working with city models that show how buildings, their groups and their shapes can effect winds at street levels-a kind of "environmental wind study." They are looking especially at how to avoid unpleasant wind effects in pedestrian areas on behalf of some developers, concerned with shoppers who will be using their centres. "It's a relatively new field." Mr. Standen said in an interview here as ho demonstrated in the NRC wind tunnel how wind effects can be studied. He used a model of a section of downtown Ottawa soon to be te-developed. He and his associates use kerosene smoke to show how the winds eddy, curl and sweep through the streets. And they use chalk dust at the street levels to show how the wind-force builds up in some areas. PULL AIIl DOWN Tall buildings "pull air down from upper levels" to ground level as well as funnelling it into the streets between the buildings, he said. So, if winds normally were six miles an hour in the area before buildings went up, they could be doubled or even tripled, with moderate gale-force gusts in areas near the building corners. Wind eddies and gusts won't necessarily be in the immediate area of the building, but often a block or so further downwind, he said. No specific studies show what wind velocities are uncomfortable for pedestrians, Mr. Standen said. Much depends on temperatures and whether the wind is steady or gusty. "But even gusts up to 15 miles an hour can be unsettling.' Such gusts wont blow you over, but they would make you uncomfortable. "Anyone envisioning putting up a complex would be wise to do this kind of measurement," Mr. Standen said, preferably early in the planning stages. The wind tunnel tests for environmental wind studies are done only in three places in North America, Mr. Standen said. Two of these are in Canada-at NRC and at the University of Western Ontario. "One may also be under way at the University of British Columbia," said the former UBC engineering graduate.
