Our newest article on high-performance strawbale building is out in this month’s Home Power magazine!
The article is all about our recent strawbale project that achieved Net Zero Energy Building certification through the Living Building Challenge. This home will be part of the USGBC’s Green Homes Tour on Oct 21, 2018.
We were honored to receive an Excellence in Energy Leadership award from SDG&E in recognition of our recent Net Zero strawbale project, the Fallgren Home. As part of the award, they made this short video that promotes the project (as well as SDG&E).
There is plenty wrong with our current energy system and it’s easy to find fault with the utility providers, so it was a nice counterpoint for SDG&E to help promote high-performance natural building. Click on the image to watch the video on YouTube
Super-insulation, thoughtful design and careful construction mean that this home stays a comfortable temperature year round in this extreme climate while using little energy. The smaller than the average photovoltaic solar array (4.1 kW) provides almost twice as much electricity as this home uses even though every system in the home is electric (no gas or propane).
“When it was cold this winter, the house stayed at about 70° without any heat. When it got hot this summer, the house stayed at about 74° without air conditioning. It’s a very comfortable house.” – Brian Fallgren, Homeowner
This home is one of only 27 in the world to achieve this certification through the International Living Future Institute, a nonprofit working to build an ecologically-minded, restorative world for all people. Using principles of social and environmental justice, ILFI seeks to counter climate change by pushing for an urban environment free of fossil fuels. ILFI runs the Living Building Challenge, which is the world’s most rigorous green building standard, as well as the Net Zero Energy Building Certification (now Zero Energy), the Living Product Challenge, and the Living Community Challenge.The ILFI NZEB certification draws from the Living Building Challenge and is a highly rigorous and regarded standard in its own right.
Whether you call them guest houses, granny flats, or second dwelling units, there’s some exciting news about them! New legislation passed in CA lifts some of the restrictions around these units, which are now all called Accessory Dwelling Units (ADUs).
Two of the most exciting features of the new rules, which went into effect on Jan 1st, are that detached ADUs can be as large as 1200 sq ft no matter what size the main house is, attached ADUs are now allowed to be as big as 50% of the square footage of the main house, and, if the project is located close to public transportation, the requirement to provide extra onsite parking has been waived. The new rules also make permitting an ADU faster and less expensive. A permitted ADU can legally be rented out, generating steady income for the owner.
This could be huge for San Diego’s affordable housing crisis! Now combine that with natural, non-toxic, carbon-positive building and we can do something real to address our housing crisis in a more sustainable way.
If you would like to explore the possibility of building a high-performance, non-toxic ADU on your property, we’d be happy to help you evaluate your options.
The straw bale buildings we helped build for the Deer Park Buddhist Monastery in Escondido were nominated for an Orchid award in the 2016 “Orchids & Onions” by the San Diego Architecture Foundation.
“Deer Park Monastery- Nun’s Residence
The form—based on a traditional Spanish Hacienda embracing a central courtyard with plantings—encourages togetherness and provides opportunities for interaction between residents. Covered walkways extend the living space outdoors, taking advantage of our temperate climate and integrating awareness of the natural world into activities like walking to the shower. All rooms are accessed through the central courtyard, helping eliminate the expense and space requirements of interior hallways.
The detached buildings help enclose the courtyard, providing a sense of protection and defining the core of the residences. This arrangement allows Deer Park Monastery to build within the existing pad and provide fire department access without building a large road around the buildings. This design also allows for phased construction that can help meet the project’s current budget, while being mindful of possible future expansion as funds allow.
Thick strawbale walls and operable windows provide thermal comfort for the buildings atop the hill which receive plentiful daylight and breezes. A beautiful garden setting incorporating existing cypress trees and views to the rest of the monastery will make this new residence a comfortable place to visit and live.
NATURE-CENTERED DESIGN FEATURES
Sensitive siting in the area of existing buildings and roads minimizes the impact on the natural surroundings.
Passive solar design lets the sun help heat the space and uses shade to stay cool. This helps reduce the need for mechanical systems and electricity.
The narrow footprint along with operable windows optimizes daylighting and natural ventilation.
Indoor / outdoor living is encouraged by covered walk-ways and central courtyard.
Super-insulated strawbale walls repurpose agricultural waste as a building material and provide comfortable, quiet interiors.
Plastered bale walls provide thermal mass, passively maintaining interior temperature
A metal roof with recycled steel content limits solar heat gain through its reflective finish.
High-efficiency glazing reduces heat gain
Fire-resistive materials provide durability along with timeless beauty
Rainwater catchment and greywater re-use supplies landscape irrigation.”

A rare opportunity to tour a straw bale house under construction! Come talk with the builders and check out how the straw bales go together to form the walls in this 1600 sq ft, two-story straw bale home designed by Hubbell & Hubbell Architects. This is the only time this job site will be open to the public until the project is completed, so don’t miss it!
We are excited to announce that our current straw bale project, the Fallgren Naturally Healthy Home, is now registered with the Living Building Challenge seeking Net Zero Energy Building certification, which is a rigorous standard that will verify that the project used the land appropriately, considered beauty, and that this home is so energy efficient that it makes as much energy as it uses.
If you are not familiar with the Living Building Challenge, it is a holistic program that evaluates beauty, toxicity, equity, health, as well as energy and water efficiency. Currently, there are only 11 fully certified buildings in the world!
