How did SIP construction help you get this job?
Owners sought us out specifically because they wanted to incorporate SIP's into their project.
SIP wall thickness and core material: 4" wall panels, 6.5" wall panels at stair wall. EPS core
SIP roof thickness and core material: 6" roof panels. EPS core
Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
SIP's were incorporated into the project's design from the very beginning, as the owners desired the high performance aspects derived from SIP's (extreme air tightness, great insulation & incredible strength with its reduced homeowners insurance premiums). Install went quickly, and the SIP's walls & roof contributed to an extremely tight home envelope, which eventually resulted in a HERS score of 9.
Describe any innovative design elements or structural engineering involved:
This home is the first of three very similar homes. We had a buildable lot size of 21’ wide and the owner desired a modern look for all three homes. The design also called for a single slope roof & a lot of windows for ample daylighting. The placement of the windows created a challenge to obtain the proper Shear wall strengths. SIP's contributed greatly to the needed increased Shear Wall strength, and when coupled with extra structural anchors in the concrete slab, exceeded the requirements. SIP's were the ideal choice for the single slope roof. Simplifying the roof erection on very tight space and giving us an excellent platform for our highly reflective standing seam Galvalume metal roof.
Please list any certifications the project received, such as ENERGY STAR, LEED, National Green Building Standard, WELL, Passive House, Green Globes or local green building programs. Only list certifications that are completed:
ENERGY STAR v3.1, Department of Energy Net Zero Energy Ready Program, Water Sense, Fortified Home
HERS Index (required only for High Performance Category and recommended for residential projects): 9
Blower door test results (ACH50) (required only for High Performance Category and recommended for residential projects): 1.9
Describe the HVAC system used on the project:
15 SEER 3 ton heat pump, 8.5 HSPF. 3 ton air handler unit (for 1950sf living space & large vaulted center section) above second floor bathroom. Ducts installed in open web floor trusses or 2nd floor flat ceiling areas & with exposed metal spiral ducts in center vault area. Includes 2 zone damper system and Panasonic 50 CFM spot ERV.
Describe any other energy-saving materials used in the building envelope other than SIPs. List U-values of windows used and the U or R-value of any insulation materials. (judged only for High Performance Category):
Anderson 100 windows (u-value 0.27, SHGC 0.19) and fiberglass insulated exterior doors (R-6.0), all ducts located in conditioned envelope, detached garage insulated with spray foam insulation
Please list any energy-efficient products or design features, such as lighting, hot water heating, appliances, passive solar (judged only for High Performance Category):
Passive solar design on an urban infill lot: the lot primarily faces east and west, creating a challenge. We incorporated a Passive solar design by eliminating all west windows (our biggest enemy of energy efficiency) except for 6 very small rectangular units. The largest are completely shaded by an existing pecan tree. We provided ample daylighting by use of east, south and north windows. The large east windows created too much heat gain during our hot summer months, so we mitigated that by use of carefully sized metal awnings. This allows the cooler morning sun to shine directly into the living space but keeps the hot sun out by 10AM. The south windows are also shaded by computer-sized awnings, which allow the warm winter sun into the living space while keeping the hot summer sun out. Highly reflective Galvalume standing seam roof & wall panels on west side of home, 100% ENERGY STAR appliances, (1) Steibel Eltron electric tankless water heater with 0.99 energy efficient factor, ENERGY STAR LED lighting throughout home, ENERGY STAR ceiling fans in living & bedrooms, all plumbing fixtures are low-flow Water Sense compliant and within a maximum 20' of water supply line
Were any solar panels installed on the project? If so, indicate the size of the system (judged only for High Performance Category):
Yes, 4.88 kW PV system (panel layout included as a supplement to application)
Please list any sustainable materials or design features not listed above, such as recycled materials, low-VOC finishes, landscaping, etc. (judged only for High Performance Category):
SITE: infill with high density (3 homes on a 92' wide x 124' long lot), native adapted (low water need) landscaping & turf grass (side note: landscaping plan was created by local university as part of their sustainable landscaping program), pervious walkways around perimeter of home & pervious alley leading to garage entry.
NATURAL RESOURCES: Preserved the native trees & protected non-construction areas.
RESOURCE EFFICIENCY & RECYCLED CONTENT/RENEWABLE MATERIALS: Stacked stories, SIP's (sustainable OSB reduces lumber used on project), interior walls framed with Advanced Framing, renewable wood materials, framing layout and structural SIP and framing plans, prefabricated open web floor trusses, James Hardie fiber cement exterior siding with recycled content (with locally supplied sand & cement in a local plant), reclaimed hardwoods installed on second floor from dwelling that was previously located on that property, locally sourced Shou Sugi Ban wood for rain screen and balcony and handrail, Trex decking contains recycled content, high recycled content standing seam roof, recycled content steel posts, concrete foundation of house was simply sealed (no added flooring) as final floor finish, concrete in foundation, garage approach and sidewalks contained local cement, sand & gravel, quartz countertops (recycled material), pre-finished windows/exterior sliding door/galvalume metal roof/Trex decking/Tamilyn Extreme Trim. Separate dumpster to recycle all wasted wood. Recycled cardboard, paper & metal. Life Cycle Analysis of SIP's, roofing, siding, steel awnings, James Hardie vertical siding & Tamilyn Extreme Trim.
INDOOR AIR QUALITY: detached garage, no fireplace, hard surface flooring, no carpet in home, formaldehyde-free cabinetry, non-toxic pest control, all paints & stains used on interior of home were low or no VOC content, return air ducts in all bedrooms, properly sized vent-a-hood and wet area exhaust fans.
Any additional comments on the project:
Our client owned a triplex that was previously located on the property. As he approached retirement, he wanted to reinvent the property, while also providing a home for himself & his wife. As such, he hired us to oversee the demolition of existing building (and harvesting of materials that can either be reused or donated), replatting process to take it from 2 lots to 3 single family lots, variances committees with the City, design and construction of all 3 residences. His vision was that each project would be extremely energy efficient, sustainable, similar in design but still unique. As such, the projects have been dubbed the "3 sisters". The first project to be completed is the home we are applying for- the owner's personal home, the 1st sister. We have just completed construction of the 2nd sister, and negotiations are underway for the sale of the 3rd lot & construction of the home on it.
Homeowner Testimonial (taken from our Houzz page review): "We wanted a green house with about 1500 - 2000 square feet. Ferrier's team turned our dreams into reality. We love our house!
We appreciated Ferrier's knowledge about green building and his help during the teardown of the existing buildings, the replat of the property and the design of the new house.
Ferrier sets a high standard for his sub-contractors! Subs had to satisfy not only us but the Ferrier Team!
We enjoyed the journey! Building a new house can be a daunting process. You need a professional like Ferrier!"
