Scott Hunter Ph.D. P.E. Consulting Engineer 5/03- present
Self employed: accomplished a variety of engineering designs for remodels and
additions and new home designs. Green Building elements have been
incorporated as appropriate.
400+ projects since 2004 from sizing a beam to a 5000+ square foot custom
home. I have also done the engineering needed to legalize numerous homes
originally built without permit.
Recent Energy Modeling Projects
80 Montcalm San Francisco CA, David Bushnell, 450 Architects Inc. –
Remodel and addition to Urban Home and workshop Kevin Stamm, owner, is a
member of Passive House Calfornia and a contractor. The goal is to use the
Passive House method to create a comfortable healthy home including his
woodshop and a studio for his wife, the artist Thea Schrack. Particular
concerns were: the Thermal bridging at a cantilever wooden deck, the losses at a
small area of existing slab on grade, and the pros and cons of using the best
American windows versus the high quality European windows designed explicitly
for Passive Houses in a severe climate.
Passiv Aggresiv Net Zero Multifamily Development for Emeryville CA –
Architecture at Zero Competition sponsored by AIA San Francisco and the
Pacific Energy Center, San Francisco CA We had just one and ½ months to
design a 225 unit development for the old Sherwin Williams Brownfield, complete
with branch library, cafes, bikepaths tied to the local system and accommodation
for significant parking - and balance the estimated energy use to achieve Net
Zero. My roles were: developing the building concept, structural design and
thermal bridging, energy estimating and sizing the solar array.
The 169 Nevada St. San Francisco CA, James Bill, ZIA Architecture,
Remodel and addition The owner and architect wanted to incorporate Passive
House ideas to make this remodel as healthy, comfortable and energy efficient as
possible without incurring a great deal additional initial expense. A particular
concern was to eliminate the need for forced air heating as a health measure.
After the initial implementation of important common sense measures (increased
insulation, insulation under the slab, air-sealing and use of heat recovery
ventilation), Significant additional savings were found when the explicit
quantitative PHPP and thermal bridging analysis was done.
7449 Cougar Lane Matuszak Home Santa Rosa Ca Mela Breen
Atmosphere Design/Build This new passive house makes no compromise in
material selection. Rammed Earth and Pisé and screen grid concrete walls were
all used to achieve the owner's and architect’s vision. As structural engineer, I
needed to avoid thermal bridges while supporting these heavy elements.
FOAMGLAS insulation, and Fiberglass reinforcement was designed and specified
to make the structure safe and serviceable without compromising the thermal
enclosure. THERM analysis was used to verify the designed performance of key
junctions.
PH mobile - Tumbleweed Tiny Homes Jay Schafer has appeared in news
stories and features internationally sharing his designs for exquisite small (8ft x12
to 20 ft) homes that are built on trailer frames. I have done the structural
engineering for a number of his designs. I came up with a SIP version that can
meet Passive House standards for even severe climates.
Selected Structural Engineering Projects 2005-2012
Harbin Hot Springs Temple, Middletown CA, SunRay Kelley Architect)
48’dia yurt type structure with highly curved glu-lams for the roof. Shiplap cedar
roof decking, straw bale and cob walls, earthen floor. Important contributions to
the design include: adding the large porches as transitions into the sacred space.
Utilize curved glulams in the roof allowing a clean expression for the strongly
curved form (when the design was brought to me there was a complicated roof
framing ) and use of Simpson Strong wall panels for the lateral system. This
allowed the use of a beautiful natural plaster on the strawbale walls.
The Wave House, Jenner CA Darrel Deboer Architect Highly curved roof
extensive glass in wall facing the ocean. Straw bale rear wall. The challenge was
to make this home strong and safe, with its unusual, highly curved roof and walls
and built on the San Andreas Fault. A curved glulam was used to tie the roof
directly to the strong concrete and steel frame in the corner, allowing the
generous placement of windows in the front wall.
Simpkins Residence, Windsor Ca Robert Zinkhan Architect Large family
compound on top of the ridge. The building system was conventional stick
frame with limited use of manufactured trusses. Here the challenge was allow the
architect to express his vision fully and precisely. This included the hall with its
18 ft ceilings and wide openings onto the terraces and the openings into adjacent
rooms through the corners where strong columns would ordinarily go. The
bold massing of the roof forms required careful attention and ingenuity to tie
everything together.
Ocean Song, Occidental CA Wall Repair. This beautiful site wall was failing
and the woman in charge of maintenance needed help to save it. There was no
money to go through the formal building permit process so I sketched a solution
on the spot, showing how to brace the wall while the foundation was rebuilt in
stages. The elegance and economy of the solution fit the wall.

I have worked as an engineer since 1988 when I completed my
doctoral work at Princeton with David Billington. After 12 years of
bridge design with T.Y. Lin International, I moved to building design
with ZFA in Santa Rosa CA. I started on my own in 2003 and have
been busy ever since. It is a delight to work as an engineer in support
of Integral Building. It is a joy to create, and support the creation of,
places that nourish the heart. See also the page on my core values
