This week's update on the Net Zero project

This Weeks update of the Madrona Street project. Things are moving forward on many fronts - a quick summary:

Energy Modeling:
The Building Performance Center distributed their first draft of two different energy models for this home on Wednesday. Thursday Greg met with them to go over the assumptions and variables. One model was created using TREAT software and the other using Passive House software - both are attached to this email. Alistair is also working on an energy model using REMRATE software and we hope to see that soon. To use these models effectively we'll need to manipulate the things we can control like insulation values, infiltration rates, window specs, and water heating to see where we get the most bang for the buck in terms of reducing overall energy loads. We'll be doing that in coming week. Alistairs REMRATE model will show us where we stand with LEED credits. Final model will be useful to Dana for design and pricing of PV system.

Drawings:
An updated set of drawings will go out next week. These will be dated Oct 1 2009 and reffered to as the Bid Set. They will be used to distribute to subs and suppliers for bids and quotes.

Bids and Estimates:
Greg met with Dean this morning to discuss suppliers and specs. He'll get me a list of KCLT contacts who may want to contribute and be involved. Cascade Joinery will take the lead however on speaking with subs and suppliers and assembling an estimate. Dean and I agreed we'd give preference to green products and local suppliers.

Permits:
A meeting is set up for October 7th with City of Bellingham green team. At that time we'll review drawings to avoid any permit issues and also discuss with them their involvment with project - and hopefully get some cooperation for this project as a potential demonstration/educational project.

LEED:
We need to register the project with USGBC and engage Alistair to begin documentation process and review drawings to make sure we get proper credit for LEED points.
