CASE STUDY- BREAKING THE BARRIERS

PREFAB WOODEN BUILDING.

Wood Barn India, is the pioneer of Wooden Houses in India.

It was setup in 2006. Wood Barn India became the first Company to offer wooden

houses in India.

The Company would be addressing the residential & hospitality requirement of the

Indian market in the initial phase of its growth plan. Wood Barn India is making

available an exquisite interplay of luxury and nature that invigorates the senses.

Wood Barn, since 2006 has tested the wooden houses under the Indian weather

conditions, before deciding to market the houses in India. This is one of the first

efforts by any Indian business entity to offer weather resistant dismantle-able

wooden houses in the country.

WOOD – FUTURE CONSTRUCTION MATERIAL CHOICE.

PREFAB WOODEN BUILDING.

Why Wood to be considered as Material for Buildings.WOOD: MOST ECO FRIENDLY MATERIAL

When considered over a building’s lifetime – from harvest of raw materials through manufacturing, transportation, installation, use, maintenance and disposal or recycling – wood performs better than concrete and steel in terms of embodied energy, air and water pollution, carbon footprint and global warming potential.

LCA analyzes the impacts of all materials and energy flows, either as input or output, of each component, from raw materials to end-of-life disposal or to rebirth as a new product.

Recycling / Extraction Construction Maintenance

Reuse / Disposal

Life Cycle of Building Products

In this graph, three hypothetical homes (wood, steel and concrete) of identical size and configuration are compared.

Assessment results are summarized into six key measures during the first 20 years of operating these homes.

Wood is low in embodied energy. It’s produced naturally and requires far less energy than other materials to manufacture into products.

Much of the energy used to process wood i such as the energy needed for kiln drying, also comes from renewable biomass,including chips

and sawdust– a self-sufficient, carbon-neutral energy source

WOOD: A SAFE AND DURABLE CHOICE When it comes to safety and durability, wood is a preferred choice In Most

Developed Countries for any private or public building project.

Fire Usually a building’s contents such as carpets, curtains and furniture are the first to burn, which means fire safety depends more on the habits of the occupants than on the structural composition. Wood-frame walls, floors, and roofs using conventional wood framing, wood trusses and I-joists can be designed to resisit Fire from 90 Min to 180 Min.by use of chemical coatings

Seismic Performance Research shows modern wood-frame structures are better able to resist seismic forces than any other form of construction.

Moisture Unlike other building materials, wood has the ability to release or absorb moisture. Its moisture content always matches that of the air, which results in natural regulation and stabilization of humidity.

The use of wood products can also improve indoor air quality by moderating humidity. Acting like a sponge, the wood absorbs or releases moisture in order to maintain equilibrium with the adjacent air. This has the effect of raising humidity when the air is dry, and lowering it when the air is moist – the humidity equivalent of the thermal flywheel effect.

AccousticsPrivacy is a major issue for building occupants. Poor acoustic performance is a common problem in buildings with large areas of hard, acoustically reflective surfaces. Such surfaces are frequently found in green buildings where the use of absorbent surfaces is often minimized dueto indoor air quality concerns.Wood is not as acoustically lively as other surfaces and can offer acoustically absorptive qualities. Generally, a wood-finished building is not as noisy as a complete steel or concrete structure.

Thermal PerformanceWood has low thermal conductivity and good insulating properties, and light

wood-frame technology lends itself readily to the construction of buildings with low operating energy.

Due to its cellular structure and lots of tiny air pockets, wood is 400 times better than steel and 10 times better than concrete in resisting the flow of heat. As a result, more insulation is needed for steel and concrete to achieve the same thermal performance as with wood framing.

Benefits of Wood

Selecting wood building products offers the following advantages related to resource

conservation:

1. Wood is 100 per cent renewable.

2. More than 90 per cent of every tree harvested in DEVELOPED COUNTRIES is utilized.

The fibre is used for the highest-value products possible, and mill residues such as chips, cut-offs and sawdust are used to make high-value composite

materials such as pulp, medium-density fibreboard and finger-jointed lumber.

3. Wood has the least embodied energy of all major building materialsthe energy consumed to grow, harvest, transport and manufacture wood products is less than for other products. Not only does wood require

less energy to manufacture into products, half of that is generated from wood waste such as chipsand sawdust. Burning wood waste for energy

is considered carbon neutral because it only releases the carbon sequestered in the wood during the growing cycle.

4. Wood is versatile and adaptable.

A building’s structural design and spatial subdivision determines its ability to be flexible in use, and adaptable so

it can meet new requirements. Separating these functions makes it easier to reconfigure the

space. Wood lends itself to this design approach, especially through the use of post-and-beam structures (in solid sawn lumber or engineered wood)

and non-load-bearing partitions made up of smaller members (either solid laminated or in stud frame construction).

5. Wood lends itself to dismantling,

A fact borne out by the continued predominance of wood and wood products in the architectural salvage market. It can generally be reclaimed

without diminishing its value or usefulness for future applications. This contrasts with materials like concrete, which is usually crushed for future

use as aggregate or ballast, or brick, which can be easily damaged when cleaned for reuse, and which can rarely be reassembled with the original

precision.

6. Structural wood members can typically be reclaimed and reused

For the same or similar purpose with only minor modifications or wastage. If desired, the same material can be remilled and fashioned into other

products, such as window and door frames, curtain wall components and cladding. A recent celebrated example is the Materials Testing Facility

in Vancouver, designed by Perkins+Will Canada Architects Co., which features reclaimed lumber from a demolished warehouse in each of these

applications. Short lengths of lumber that may be a byproduct of the remilling process can typically be used for bracing and blocking elements.

Wood components too small to reuse and leftover wood chips and sawdust can be processed into mulch for landscape use or to provide organic

material to promote decomposition in landfills.

WOODEN MARVELS:WORLD’S TALLEST TIMBER RESIDENTIAL BUILDING

• In the Borough of Hackney in London stands Stadthaus, the world’s tallest modern timber structure.

• Stadthaus is a nine-storey high- performance residential building of which the top eight are constructed from cross-laminated timber and designed according to passive design principles.

• Pre-fabricated timber panels comprise the load-bearing walls and floor slabs as well as the stair and lift cores.

• Each panel is made up of five layers of timber positioned at 90 degree angles and glued over their entire surface, making a panel that could be compared to precast concrete.

• To address global concerns about carbon emissions, the design team made use of pre-fabricated panels that provide several advantages:

• A. improved thermal performance, • B. a continuous air barrier, • C. ease and speed of construction, and • D. waste minimization.

• Because wood products continue store carbon absorbed during the tree’s growing cycle, this modern timber building will actually keep 205 tons (186 tonnes) of carbon out of the atmosphere for its entire service lifes—or longer if the materials are reclaimed and manufactured into other products. within its structure over its lifetime.

• CLT construction reduces wetting potential because prefabrication reduces construction time. CLT also provides considerable insulation with an inherent R-value of about R-1.2/per inch resulting in R-4.2 for 3 1⁄2” thick panel. The solid panel also reduces convection in the assembly.
