David,
I wanted to ask you about your first detail. Do you intend on running the glass up to the top of the parapet wall? You are showing a finish on the interior but glass running up the exterior edge. Is this for aesthetics or do you have something else planned for this area? My other question is do you plan on having planting on your roof? I thought you were in certain areas and was wondering where those were going to be implemented and if they would be addressed in the details if you were. Good work!
Hey Jaclyn,
Yes glass will run to the top of the parapet. In my green research, I found a glass product that has photocells in it (Photovol). It's available in different light transmittances and I plan on using the darkest one, which will be similar to using spandrel glass, plus it happens to be the highest watt output. The stud wall behind is for my roofing to attach to.
I plan on having a typical roof garden detail... just don't have it completed yet and I wanted to get back over to "building services".
Thanks for the post, I was looking at your latest posts a little while ago and am getting ready to comment...
David,
Yes, I am aware of the photovol. I was researching it this week! You may see it applied in my project as well.
David,
Nice start. Make sure the insulation is continuous from vertical to horizontal surfaces; behind the photovoltaic glass panel, at the brick parapet edge, where wall and concrete slab meet, where the building meets the ground. Exposed slab edges are really a no-no in green building. The space below the first floor is a parking garage(?). The fresh air requirements make this space practically an exterior space. The ceiling therefore needs to receive insulation. If you have water (plumbing or hydronic heating) under that ceiling you will need to provide a heated plenum.
The photovoltaic glass parapet is an interesting proposal. I have a few questions however: To be true to your original parti, shouldn’t you have a projecting roof to shade the glass wall underneath? The vertical glass wall is not the most efficient surface for photovoltaics. Wouldn’t you be better off taking this area and mounting it to the south facing sloped areas of your light scoops on top of the roof? Your detail currently shows a shadow box at the top of your curtain wall. Depending on your spandrel, you create a volume behind the glass that will be heating up and potentially creates negative conditions for your curtain wall.
Werner,
Thanks for the comments. I would really appreciate the ability to talk to you to discuss some of your comments on my other posts. Blogging is great but doesn't allow a conversation which I think would be very helpful. I emailed you Friday late asking to talk this weekend. I will call you on my dime! Please email where and when would be convenient for you.
Thank you,
David
David,
sorry, I didn't check my work email over the weekend. Call me anytime tomorrow, if you still would like to chat...
David,
It's hard posting last but I agree with much of everthing here said. The biggest thing that stood out to me was the continuous insulation at the parapet details. I think you have a good understanding how your building will get put together and will move on to your elevations now.
