Completely off grid homes epitomize the very standard of ‘autonomous living’. Without any connections with the main transmission line, such dwellings generally rely on stand alone systems (SHS) or mini grids for specialized communities. And, in allusion to this fascinating scope, most of them fall into the very exclusive category of self sustaining buildings. This means they have their own water supply lines and sewer components, generate their own electricity and even incorporate various indigenous yet sustainable sources for habitation. In short, they tend to eschew any kind of public utility service, thereby embodying the true sylvan side of living.
Hi’ilani Eco House
An apt confluence of passive architectural techniques and advanced design considerations, the Hi’ilani Eco House is to be built on the Big Island of Hawaii. Conceived by Robert Mechielsen of Studio RMA, the off grid dwelling is to self produce all of its essential services like energy, water, cooling and ventilation systems. Construction wise, the house is being infused with Structural Concrete Insulating Panel (SCIP) technology, which insinuates an indirect temperature control mechanism. This is complimented by natural cooling and ventilation mechanisms. Moreover, in a bid to further reduce energy needs, the house features inverted butterfly roofs that would pose as a water catchment system, while also improving clean solar energy harnessing. In fact, the building is equipped with a 10KW solar photovoltaic system for all its electrical needs.
Designers from Frank Lloyd Wright School of Architecture have envisioned their version of pre fabricated home, which can stand the rigors of a desert environment. Christened as the Mod Fab home, this single bedroom dwelling relies on its hybrid mechanism of energy sustenance. That means, it can be connected to the main gird, and it can also produce its own electricity from a built in solar array. Other energy efficient features include low consumption fixtures, natural system of ventilation and rainwater harvesting with gray water reuse systems.
Fusing futuristic elements with a clear vernacular essence, the Cubolar House conceptualized by industrial designer Edward Castro is envisaged for the year of 2050. To be built in a modular scope, the construction will utilize only locally available building materials. Apart from that, the dwelling will exhibit a complex terraced roofing system with solar panels being integrated on each individual floor. And, even beyond generating clean power for its inhabitants, the house will also feature energy saving attributes. These include an advanced rainwater collection system that stores water in a cistern below the deck, for after usage in bathrooms and toilets.
Envisioned as a luxurious dwelling with true off grid aspects, the Kokopo House aptly embodies the opulent side of green technology. Located near the Tarvurvur volcano, the building certainly emanates a bucolic essence. However, beyond the visual allure, every energy related feature in the house is derived from natural sources. For example, its roof consists of two separate rainwater collecting tanks for drinking as well as kitchen and toilet utilities. The water heating system also utilizes solar energy for working. Moreover, the design conforms to special geometric pattern for better circulation of natural air.
Supposedly inspired from the mundane scope of a bike rack, Palo Alto architect Joseph Bellomo has created something uniquely enticing. Dubbed as the House Arc, this off grid pre fabricated dwelling was conceived for the beautiful island of Hawaii. Structurally, the design bears a conspicuously tubular steel armature, with concrete or wooden deck as the pedestal along the ground. Then the entire 800 sq ft cylinder was draped in highly insulating translucent polycarbonate plastic for passive temperature control. And, finally, the $100,000 house utilizes roof mounted PV cells for clean and green power generation
Mobile home built with rustic components
Posing as an idyllic countryside home, there is more to the above pictured conception than meets the eyes. Designed by Richard and Carol Atkinson, every constructional element associated with the house (with the exception of steel) is recyclable. These materials include some truly rustic components like straw roofing, sheep’s wool insulation, hemp for plaster strength and linseed for mastic around windows and doors. Furthermore, the house is off grid in its power consumption, with integrated features such as wind turbine, photovolataic installations and solar heating systems.
The Casa ISEAMI House
Located in the exotic rain forests of Costa Rica, the classy looking Casa ISEAMI is infused with a dual system of off grid power generation. The double storied building utilizes an on site hydropower system, which can generate up to 800kWh of electricity per year. This sustainable mechanism is complimented with a rooftop solar system that generates 10,800kWh annually. Other energy efficient aspects include passive solar design considerations for shades and rainwater collection; along with solar systems for heating of water.
Looking like a futuristic iteration of our countryside homes, the aptly named Zero House does live up to its name. Featuring nigh zero carbon footprint, the wing like roofing is strewn with solar panels for clean power harvesting. The roof component also contains a 2700 gallon capacity cistern for storing water as well as accentuating upon the plumbing mechanism of the structure. And, since we are talking about utilities, the building features a basement compost container for organic absorption of the waste. Finally, to notch up the green level, the interior lighting fixtures correspond to LEDs for improved energy efficiency.
iT off-grid house
Prefabricated housing has come a long way from those mere simplistic sections quickly assembled on site. Exuding the same level of class and grace as our conventional high end dwellings, the so named iT off grid house from Taalman Koch architects ardently follows this modernistic trend. Insinuating a fully modular scope, the building comes with a 1200 sq ft area. The designers have also opted for optional sections like kitchen, bathroom and even solar installations, which can be ‘added’ to the structure according to user’s convenience.
Custom residential house in Chub Cay
To be completely powered by solar and wind energy, Affiniti Architects has contrived a custom dwelling plan for Chub Cay’s eco conscious residents. This off grid system will feature an expansive 3000 sq ft area, with integrated renewable power systems like four vertical Tangarie Alternative Power wind turbines and solar panel arrays. The architects have also given their attention to passive energy saving components like metal roofing to reduce cooling costs and glazed R5 windows for added insulation from outdoor climate.
