The intent of the workshop was to figure out how we would put everything back together and how to integrate the most appropriate and efficient sustainable strategies, systems and materials. The cumulative expertise and creativity of the workshop participants was to help us to organize our ideas, make sure that various <a title=\"Dusting off the wish lit\" href=\"https:\/\/blog.delafleur.com\/?p=791\" target=\"_self\">wish list<\/a> items are compatible, and make sure we accomplish our <a title=\"Pilot Project Design Principles\" href=\"https:\/\/blog.delafleur.com\/?page_id=15\" target=\"_self\">project principles<\/a>.<\/p>\n<p>A rehab is not a cheap undertaking, nor is a sustainable rehab. If we spend all this money, I would like to make sure that we get things right the first time round and that we can count on a reasonable payback and\/or effective environmental footprint reduction. The workshop was an investment that will help us in this regard.<\/p>\n<p>I developed a list of items to discuss and resolve in the workshop:<\/p>\n<ol>\n<li>Cathy and I very much liked the layout of the building. We now have <a title=\"Measure-mania!\" href=\"https:\/\/blog.delafleur.com\/?p=764\" target=\"_self\">floor plans of the existing conditions<\/a> that include some of the original building features we discovered during the deconstruction process (see also <a title=\"Rediscovering our living room - Part 1\" href=\"https:\/\/blog.delafleur.com\/?p=563\" target=\"_self\">06\/13\/2009<\/a>, <a title=\"Rediscovering our living room - Part 2\" href=\"https:\/\/blog.delafleur.com\/?p=579\" target=\"_self\">06\/15\/2009<\/a>, <a title=\"We had a pantry - once...\" href=\"https:\/\/blog.delafleur.com\/?p=588\" target=\"_self\">06\/17\/2009<\/a> posts). We would like to restore some of those original items and, in some instances, change their function \u2013 for instance turning the <a title=\"We had a pantry - once...\" href=\"https:\/\/blog.delafleur.com\/?p=588\" target=\"_self\">former pantry<\/a> into a half bath room. I would like to review the floor plan with the green team to see what other ideas may emerge.<\/li>\n<li>Insulation is a very big, and as it turns out, complicated topic. It has a significant impact on many of the other systems we will need to operate the building. What kind of <a title=\"Wikipedia - R-value\" href=\"http:\/\/en.wikipedia.org\/wiki\/R-value_(insulation)\" target=\"_blank\">R-value<\/a> do I really need? What kind of insulation would suit our project best? What kind of windows would go hand in hand with the insulation?<\/li>\n<li>I needed some input on space heating and domestic hot water. We favor a solar hot water system. But what would be the peak load the system has to meet \u2013 after we insulated the building? What kind of heat distribution system would work with solar hot water? We would like a biomass furnace as a backup for cold and cloudy days, but is this realistic?<\/li>\n<li>We plan to create an airtight building envelope (stop the building from leaking air in our out). That will, by definition, require a good ventilation system to keep the indoor air healthy. Can we rely on passive ventilation or do we need an active system (fans and ducts)? Does a <a title=\"ToolBase Services - Energy and Heat Recovery Ventilators\" href=\"http:\/\/www.toolbase.org\/Technology-Inventory\/HVAC\/energy-recovery-ventilators\" target=\"_blank\">heat or energy recovery unit<\/a> make sense? How do we size the ventilation system and how much energy would it need to operate?<\/li>\n<li>The findings from the insulation, heating and ventilation discussion would bring us back to the floor plans and layout. Where should we place the various utilities and how much space would they take up? How could we route things (like ducts or pipes) in effective ways? Would our ideas require changes to the floor plan after all?<\/li>\n<\/ol>\n<p>I put these items into a draft workshop agenda and ran them by my friends <a title=\"The Plant Chicago - vertical farming and industrial reuse\" href=\"http:\/\/www.plantchicago.com\/blog\/\" target=\"_blank\">John Edel<\/a> and\u00a0 Ted Krasnesky (Pepper Construction). Both pointed out that I was missing baseline data on basic energy needs. That data would be the foundation for the workshop discussions (i.e. how well would the insulation work and how much heating do I really need?).<\/p>\n<p>I needed an energy model. More importantly, I needed to find someone competent who can run that energy model for me \u2013 quickly. Never mind the bad economy. Energy consultants in the residential green building business seem to be extremely busy.<\/p>\n<p>A visit to <a title=\"Chicago Green Drinks\" href=\"http:\/\/www.foresightdesign.org\/greendrinks\/\" target=\"_blank\">Chicago Green Drinks<\/a> earlier this year got me out of this rut. I remembered a presentation by Corbett Lundsford (<a title=\"Green Dream Group | Home Energy Audits | Chicago Energy Efficiency\" href=\"http:\/\/www.greendreamgroup.com\/\" target=\"_blank\">Green Team Group, LLC<\/a>) about energy audits and modeling. Corbett was kind enough to squeeze me into his schedule. He ran a <a title=\"AEC - REM Home Energy Analysis Software\" href=\"http:\/\/www.archenergy.com\/products\/rem\/\" target=\"_blank\">REM\/Rate energy model<\/a> for me based on the floor plans and building performance parameters we discussed.
