took PPD this morning, was a little taken back of how different it is to the practice exam ( a lot niche questions / diagrams) - that being said anyone know a good study resource on locating sites just based of latitude ? ex a bldg in 35 degree north latitude - thanks

I'm guessing they asked you to choose a passive heating/cooling strategy based on climate zone, based on a given latitude. In that case it's either gona be a small number (hot) or large number (cold). I don't think it will ever get more specific than that.

Yes it was along those lines, now would 35 degrees be considered a low or high number ? i have 0 exp with this type of stuff - thank you for your response j

For questions like that ask you to identify or locate a site just by latitude (like 35 degree north), it is all about understanding climate zones and solar angles. A building at 35 degree north would be in a warm temperate zone (think parts of the southern U.S., like North Carolin or Central California). It is helpful to know the general characteristics like mild winters, hot summer, and a sun angle that is a high in summer and low in winter making passive solar design and shading strategies really important. See AGS, Energy and Environmental Design, Climate section for more context.

Understanding latitude and sun path is critical for PA PPD & PDD. Make sure you understand this well before taking another exam. Good luck!

haha yeah passed PA two weeks ago , This test felt like an extension of it! studied a bunch on suns effect - was definitely thrown off by it not giving me a State, climate zone or saying cold - thank you so much

Heating cooling and lighting is highly helpful for both PA & PPD.
I also uploaded a few free videos to my website. You can check it out from below link.
