Hey Chris, checked you out on LinkedIn. I like your positive take on things in this topsy-turvy field. Thanks very much for adding me.

Hi Chris,

I think that's a great idea! Yes, we should do that. Want to try to talk about it a little later this week? I am extremely busy until tomorrow evening, but should be relatively free Thursday or Friday. If you have some preferred time, let me know, and I can give you call. And I really liked your Cart Before The Horse article, BTW, just haven't had a chance to comment yet. Have a good one!

Congratulations of being featured, Chris (and for a second time, no less!)

Hi Chris, Agreed on all that. Review board issues are yet another problem area we could possibly draft some general solutions for. Also, I wanted let you know that my good friend Juliana Inman from Napa, CA, a highly experienced preservation architect, has also joined HEP and our group. She's been through much of what you're descrbing and will be a great asset to the group. Regarding the presentation, I doubt there'd be any recording, but I will definitely get you a copy of the presenation slides. Have a good one!

Thanks Chris! 

 

And I'm glad you're excited about the Historic Home group. I am too. Wasn't aware of your preservation background, but I think it's great that you're in a position to combine preservation knowledge with energy efficiency. I think these are very important areas that need to be unified. I am in the process of compiling some detailed discussion topics to post to the group about the difficulties of retrofitting older homes and buildings. If you don't mind, I will run them by you for your input before posting. I think between you, me, Allison, and Sean, we can make this a very successful HEP group.

 

Also, just so you know, in two weeks, I am giving a presentation on three ancient homes that I am in the process of surveying, at the Timber Framers Guild spring meeting. I am using SketchUp to build timber frame models, along with some Ruby extensions that support the creation of timber components (developed by another Guild member). That's why I like SketchUp so much. Its application is almost unlimited.

 

Have a good one, Chirs!
