GREEN CONSTRUCTION

Utilizing fast growing organic materials, vitalized water and new construction techniques to provide sustainable housing alternatives

description

In an effort to address sustainability and reduced costs in the housing and construction industries, Dúnedain is experimenting with alternative forms of materials and techniques. These materials include waste plastic combined with fast growing organic crops.

High voltage “vitalized” water will play a role in providing faster growing organic materials with increased nutrient density.

organic materials

Dúnedain has developed a natural method to increase the electrical potential of water. This high voltage “vitalized” water has a significant impact on crops - 2x biomass, increased nutrient density and they reach maturity faster. Fast growing sustainable crops like bamboo and hemp are excellent carbon sinks - they absorb more carbon dioxide from the atmosphere than trees.

Bamboo

Giant bamboo can grow 3’ per day. Construction-ready bamboo can be available in just a matter of weeks after planting.

Considering its strength-to-weight ratio, bamboo’s tensile strength is more than 3x that of steel.

Hemp

Hemp - fiber and shiv - can be used in a diverse range of products and applications. Our current focus is hemp’s use as insulation and filler adhesive material.

With vitalized water, Dunedain’s hemp grow experiments have shown 2.5x increase in biomass - reaching maturation 25% faster.

Soybeans

Our soybean experiments have shown over 100% biomass increase with vitalized water.

New developments using soy-based adhesives are extremely encouraging, particularly for the use of plywood and engineered lumber alternatives.

sustainable construction products

Dúnedain is experimenting with alternative forms of construction products, with an emphasis on utilizing fast growing organic crops as raw materials. These products include:

Structural insulated panels - SIPs - are becoming more pervasive in construction. They are made of an interior and exterior “wall”, or skin, which provides structure; they surround a layer of insulation. SIPs allow uniform and rapid construction - they are built in a controlled factory environment. However, SIPs traditionally use old construction materials and techniques not necessarily friendly to the environment.

Dúnedain would like to develop a new type of SIP using a combination of bamboo for the structure walls and lightweight hemp as the insulation. Our initial plan is to design customized yet affordable tiny homes using these SIP panels.

Interwoven strands of bamboo surrounded by hemp stock mixed with soy-based adhesive could revolutionize the use of plywood. The walls, floors and roofs of any structure could utilize this new type of plywood - a big step forward for the green construction movement.

Rough example of interwoven bamboo strips

The inner part of a hemp stalk - the shiv, or hurd - is an excellent form of insulation. Hemp insulation may be part of the SIP, or installed separately in the form of batts. It can even be poured like concrete, aka “Hempcrete”, or made available in the form of blocks - like “lego” blocks.

Hemp Shiv

Hemp shiv (or “hurd”) is an excellent thermal insulator - tons of air pockets.

Hemp Insulation Batt

Hemp insulation batts have an r-value of 3.5 per inch. Simple to use in place of conventional batt insulation products.

Hemp Blocks / "crete"

Hemp shiv can be mixed with lime to create structural blocks, or to be poured into forms.

The R-value rivals that of traditional types of insulation, while also providing thermal mass - they store and release heat energy.

Engineered lumber consists of a range of wood products that are mixed with adhesives to form man-made composites. In this case, we are primarily talking about beams, joists and trusses. For our Green Construction initiative, bamboo and hemp will replace conventional lumber materials, and soy-based adhesives will replace toxic chemical adhesives.

housing + creativity

The aim of the Green Construction project is to provide affordable, carbon neutral housing while never sacrificing beauty and creativity. We would like to provide tiny houses, not-so-tiny houses, and even tree houses utilizing the new techniques mentioned. We even have plans to power these homes with electrical generators running on water. The hydrogen from the water molecule is a very efficient fuel where water is the exhaust.

Next steps

Dúnedain is looking to expand our grow experiments. We are interested in performing larger scale bamboo, hemp and soy grows, comparing vitalized vs control water effects. We are also interested in designing and building new products (mentioned above), as well as water-powered tiny homes.
