80 plus years of re purposing a building can take a toll on the framing (note the original building has no exterior sheathing.  corrugated tin over fiberglass batts….

In cooperation with Moretti Architecture and Reineking Construction Sustainable Building Design is renovating a 80+ year old warehouse building in Central Missoula into new office space for Five Valleys Land Trust.  The existing structure is the East portion of the Montana Natural History Center.   The building will be gutted to the studs. All demolition waste will be either reused or recycled.  The renovated structure will incorporate a number of energy efficient features including R28 Walls,R45 ceiling insulation, Serious 525 Windows, and energy efficient lighting and HVAC systems.  The existing structure is somewhat of an eyesore, and will be re-clad in steel and stucco siding.  Check back for updates as the project is currently under construction.

Completed in late summer of 2011 by Reineking Construction This new home in Missoula features R40 walls using double stud construction and dense pack cellulose.  Attic insulation will be R60.  Fiberglass framed triple glazed windows from Serious Windows average U.18.  The homeowners have installed temperature and air quality monitoring equipment throughout the home and are actively monitoring the home’s environment.  This is a rare opportunity to collect actual field data to verify the energy model used to design this home.

The South Elevation of the house. The house was positioned on the lot to take advantage of  views of  Lolo Peak  as well as some passive solar gains.  The South facing windows use  Serious 525H glazing for improved solar gain in the winter.  Overhangs are tuned to help avoid overheating in the summer months.

The Front porch features reclaimed timbers and a low maintenance stained concrete floor.  The house has 3 coat stucco siding on a fully vented rain screen to ensure the  durability of the 12″ vapor open cellulose walls.

The home has been designed to accommodate primarily single level living, featuring wheelchair accessible living areas throughout.  A walkout basement takes advantage of the gently sloping site and  provides extra space for future needs.

Built by Creekside Construction, The house will feature R 35+ walls, using double stud construction and dense-pack cellulose, R65 ceilings, u.18 windows by Serious Energy.  heat for the home will come from radiant floors and a beautiful and efficient, Tulikivi wood burning fireplace.

The features R40 SIP  Walls, R75 Attic Insulation, Gienow triple pane windows, average U value = .18, Tested Air Infilatration  0.9 ACH50, 95% efficient modulating forced air natural gas furnace,  90% efficient energy recovery ventilator, tankless hot water heater

The front Porch of this contemporary prairie style inspired home features  plank form concrete and reclaimed fir timbers from the Stimpson Sawmill in Bonner, MT.

The South porch features columns crafted from salvaged hand hewn oak barn timbers from heritage timber.  The siding on the East wing of the house is cold rolled raw steel.  In Montana’s aired climate the steel will slowly rust.  Once the initial layer of rust sets it will protect the steel from rusting further and result in a unique, no maintenance exterior.

The house features 10″ thick SIP (structural insulated panel) walls.  This system of building energy efficient homes can offer an economical and fast alternative to conventional stick framed exterior walls and roofs.  The panels are precut in a factory and delivered onsite in sizes up to 8 ft by 24 ft.  The wall package for this home was installed in less than 2 days by a crew of 4.

The front porch walls are plank formed concrete.  The deck boards from the salvaged house were used to form the walls.

To save costs and resources the home was built on the foundation of a 1970′s era split level home.  The previous home was poorly built, and did not meet the new homeowner’s requirements for a single level residence.  The old house was deconstructed and almost 90% of the house was salvaged for reuse. by Deconstruction Services, A division of Home Resource, Missoula’s local non-profit building materials reuse center.
