Modeling Tip: Sloped/Pitched Roofs

When calculating building downwash using the US EPA BPIP and BPIPPRM* programs, you may encounter the need to model a building with a sloped roof.  As BPIP is only capable of modeling buildings with flat roofs, you will need to approximate the roof.

It is always advisable to check with your regulator to learn how such buildings should be modeled, but two possibilities are given below:

1. Single Tier (Conservative)
   
   Creating a building with a flat roof at the height of the sloped roof’s peak will give you a larger building profile, therefore giving you a conservative estimate of the building downwash.
   
   



2. Multiple Tiers (More Realistic)
   
   By creating a building with a series of tiers that decrease in size, you can approximate a sloped roof.  The more tiers you use in this approximation, the more realistic it will be.
   
   

*Building Profile Input Program (BPIP) and Building Profile Input Program for PRIME (BPIPPRM) are US EPA programs that calculate downwash values for input into the ISCST3 and AERMOD air dispersion models.

We are currently accepting submissions for the Monthly Modeling Tip which appears in our newsletters.  If you have a modeling tip that may benefit a variety of people, please send it to us at support@weblakes.com.   Your name and the name of your organization will appear below the tip providing you with greater exposure.

Effects of Climate Change on Arctic Observed

It's becoming harder to find the right snow to build an igloo, and melting permafrost is turning land into mud.  With climate change the nature of the Arctic is changing, too, in ways that worry the people who live there.

Energy Companies Dominate Eco-Sector

Renewable energy companies continue to take the lion's share of the top spots in an economic index that measures the market value of businesses in the environmental sector.  The widely respected Impax ET50 index lists the world's 50 largest listed companies operating in diverse areas from energy and alternative fuels to waste and water.

Fresh Air Problems for Europe’s Cities

Air pollution rose above recommended levels in all 20 European cities sampled for a European Environment Agency survey in 2000. The survey, published in March, included Antwerp, Athens, Berlin, Brussels, Copenhagen, and Lisbon.  It found that air-quality limit values were frequently exceeded, especially in streets and other urban hotspots.
