These four fine residences represent an evolution of design and convergence of technologies resulting in Carbon Neutral Living and Transportation. Off The Grid Design LLC, The Klein Family Trust, RG Architecture, and project partners are building the first multi-unit "Nanogrid" project to be offered to the residential market in the USA. The project, known as "Sol Lux Alpha" will be complete and commissioned by Sring of 2018. A new energy paradigm is dawning and this building and others similar are at the nexus of this technological shift. A connected grouping of similar renewable energy "net positive energy" buildings are designed to interconnect and begin forming Community Microgrids. "Sol Lux Alpha" has a 45 Kw bifacial BIPV array on a raised trellis over the roof-top lounge deck/garden space. Each of the 4 units has 41.5 kWh of energy str=orage and management from Project Partners TESLA Energy. The common areas including elevator  has 24 kWh of "Blue Ion" LiFePo4 Energy Storage frpm Project Partners Blue PLanet Energy. The buiolding is designed also with BIEV (building integrated electric vehicle) infrastructure with future-planned V2B (vehicle to building energy) architecture built in to be future ready. The "Passive House" Designed and Certified structure represents the pinnacle of ultra energy efficient design, allowing excess renewable energy generation beyond building needs for on site EV charging.

The convergence of technologies as planned and designed results in a new "Zero Carbon Living + Transportation" system. The savings in energy costs and $300/mo vehicle fuel costs PER UNIT can represent a $5,400 per year savings for each unit, even at today's low energy costs.

The building will save many tens of thousands in energy cost and can be an asset to the community and city during power disruptions or natural disaasters. When one factors in the societal cost benefit in ghg reductionsmove toward decarbonized societies. We are developing this as a new system of design/development for ourselves and others to follow, for people, for the planet, and for profit of all.
