Serious Materials & Kevin Surace

Serios Materials toodab päris lahedat nodi (parimat ehitusmaterjali toodab mu meelest loodus ise st. puitu, põhku, savi, liiva, kivi jm. taolist):

1) EcoRock
Traditional gypsum drywall has remained virtually unchanged since its invention over 100 years ago. Our increasingly fragile world requires rapid innovation to meet the changing conditions of our environment.

EcoRock uses 80% less energy to produce than gypsum drywall
Naturally cured and dried, EcoRock eliminates the energy-intensive, high-C02 generating calcining and oven-drying found in gypsum drywall production.

EcoRock is made of 80% recycled materials
EcoRock is made using 80% post-industrial recycled waste, including waste from steel and cement plants—with no gypsum.

EcoRock is designed to be fully reutilized at end of life
EcoRock can be used as a pH additive for soils and can be returned to the production of EcoRock and other building materials as a valuable raw material. Unlike gypsum, EcoRock may be safely disposed of in landfills if necessary.



2) SeriousWindows are the most energy-efficient residential windows on the market today.

The ‘built environment’ – our man-made surroundings including our homes and offices – are responsible for 52% of energy use and greenhouse gas emissions worldwide – compared to only 9% for cars and light trucks.

We aim to slash that number by reengineering common products that use or lose the most energy.

Energy-Saving Windows
Windows represent the single largest opportunity for improvement. 39% of all emissions are tied to building operations, with 38% of that for heating and cooling. Up to 40% of that energy – and cost – literally goes out the window. The wasted energy results in over 250 million tons of emissions per year.

Skeemi selgituseks, et vastavalt Vabariigi Valitsuse 20. detsembri 2007. a määrus nr 258 Energiatõhususe miinimumnõuded järgi on Eesti numbrid sellised:

§ 5. Üldised nõuded välispiiretele
(3) Soojustuse valikul tuleb lähtuda sellest, et ehitis oleks hea energiatõhususe tasemega. Üldjuhul piiratakse elamute välispiirete summaarset soojaerikadu köetava pinna ruutmeetri kohta väärtuseni 1,0 W/(m2K). Väikemajade soojustuse valikul võib aluseks võtta järgmised lähteandmed: välisseinte soojajuhtivus 0,2–0,25 W(m2K), katuste ja põrandate soojajuhtivus 0,15–0,2, akende ja uste soojajuhtivus 0,7–1,4 W(m2K), kusjuures lõplikud valikud sõltuvad hoone kompaktsusest ning kütte- ja ventilatsioonilahendustest. Muude hoonete optimaalne soojustus sõltub eelnevale lisaks oluliselt ka vabasoojusest.

Ma ei suutnud kuskilt leida SeriousWindowsi poolt esitatud U ühikut - vbl. tulevnevad need ulmelised numbrid sellest & on lihtsalt mingi kaubanduslik trikk.

Tegelt peakski tegema eraldi akende teema.
Lisaks klaasipaketi soojapidavusele tuleks arvestada siis ka lengide soojapidavust.
Seda aga eriti tootjate lehtedel ära mainida ei soovita.
Mingi ülevaate võiks ju nendest siiski tekitada.

Novacemi betoon

Taavi @ 11.01.2010 14:54 | Registreerunud: 01.04.2003

CO2 rindel on ehitus vaenlane nr.1 ja põhiline CO2 emiteerija ehituses on omakorda betoon/tsement .

Novacem is developing the new generation of green cement systems that will help combat global warming by locking atmospheric CO2 into construction materials.

Our cement uniquely combines the sustainability of timber and the recyclability of metal with the technical properties and high thermal mass of concrete. Its use therefore minimises CO2 emissions during building construction, operation and disposal.

Our novel recyclable cement system is based on magnesium oxide and special mineral additives. In contrast to Portland cement, its manufacturing process causes minimal CO2 emissions and it requires lower temperature processing. It hardens by absorbing atmospheric CO2 and therefore offers the unique potential to develop a range of 'carbon negative' construction products.

History of fabric formwork

While several 19th and early 20th Century patents exist for fabric formwork, the first practical applications occur in the mid-Nineteen Sixties with the introduction of fabric formwork for erosion control and pond liners. The work of B. A. Lamberton, E. W. Bindhoff, and others in the field of geotextiles led to the first commercial use of fabric formworks.

In the 1970’s the Spanish architect Miguel Fisac used thin plastic sheets as formwork for textured wall panels.

In the late Nineteen-Eighties and early Nineteen-Nineties, three men working independently and unaware of each other, invented a variety of techniques for forming above ground structures in fabric forming. This work represents the first broad flowering of this technology for above-ground structures.

Kenzo Unno, an architect in Tokyo Japan, invented a fabric formwork system for in-situ cast concrete walls.

Rick Fearn, a builder and businessman in Canada, invented a number of fabric formwork techniques, leading to the development of a series of foundation footing products now manufactured and sold by Fab-Form Industries in Surrey BC.

Mark West, an artist, architectural educator, and builder invented a series of techniques for constructing fabric-formed walls, beams, columns, slabs, and panels. He is now the director of the Centre for Architectural Structures and Technology (CAST) at the University of Manitoba’s Faculty of Architecture, in Winnipeg MB, Canada. CAST is the first research centre dedicated to fabric formwork technology and education.

Structural insulated panel - SIP

Taavi @ 20.03.2010 17:20 | Registreerunud: 01.04.2003

... asja nimi on Structural insulated panel

Structural insulated panels (or structural insulating panels), SIPs, are a composite building material. They consist of a sandwich of two layers of structural board with an insulating layer of foam in between. The board can be sheet metal or oriented strand board (OSB) and the foam either expanded polystyrene foam (EPS), extruded polystyrene foam (XPS) or polyurethane foam.

Lean construction & Integrated Project Delivery (IPD)

Taavi @ 24.03.2010 19:06 | Registreerunud: 01.04.2003

Lean construction is a “way to design production systems to minimize waste of materials, time, and effort in order to generate the maximum possible amount of value (Koskela et al. 2002) ”

Lean construction sai alguse Toyota tehase lean manufacturing praktikast. Fordism on tänaseks ajalugu ;)

Basically, lean is centered around preserving value with less work.

The four goals of Lean manufacturing systems are to:
1) Improve quality: To stay competitive in today’s marketplace, a company must understand its customers' wants and needs and design processes to meet their expectations and requirements.
2) Eliminate waste: Waste is any activity that consumes time, resources, or space but does not add any value to the product or service. There are seven types of waste:
- Transport (unnecessary movement of materials)
- Inventory (excess inventory not directly required for current orders)
- Motion (extra steps taken by employees because of inefficient layout)
- Waiting (periods of inactivity)
- Overproduction (occurs when production should have stopped)
- Over Processing (rework and reprocessing)
- Defects (do not conform to specifications or expectations)
3) Reduce time: Reducing the time it takes to finish an activity from start to finish is one of the most effective ways to eliminate waste and lower costs.
4) Reduce total costs: To minimize cost, a company must produce only to customer demand. Overproduction increases a company’s inventory costs because of storage needs.

Integrated Project Delivery (IPD) is a delivery system that seek to align interests, objectives and practices, even in a single business, through a team-based approach. The team primary Team Members would include the Architect, key technical consultants as well as a general contractor and key subcontractors.

VIG e. vacuum insulated glass

Taavi @ 13.08.2010 10:24 | Registreerunud: 01.04.2003

Sakslased on lõpuks välja töötanud pm. toimiva vaakumklaaspaketi konstruktsiooni.

With the proposed tightening of energy-saving regulations, today’s windows with conventional double glazing and Ug values of 1.0 W/m²K will no longer meet thermal-insulation requirements in a few years. Triple glazing provides adequate insulation values (with an argon filling and two low-E layers, for example, Ug = 0.7/Wm²K), but it results in a 50 per cent greater weight and large system thicknesses of between 30 and 50 mm.

Vacuum insulation glazing marks a new approach. Whereas the insulation effect at the transition from double to triple glazing is the outcome of greater system thicknesses, in the case of vacuum glazing a genuine qualitative improvement is achieved by obviating the thermal conduction caused by the gas in the cavity between the panes. Using this form of construction, even with double glazing, excellent insulation values of Ug = 0.5/m²K can be achieved with system thicknesses of less than 10 mm.

Technically speaking, the production of vacuum insulation glazing depends on evacuating the gas from the cavity between the panes and thus reducing the pressure to levels below 10-3 mbar. As a result of the external atmospheric pressure that is caused by the evacuation of the cavity, the panes of glass are subject to a load of 10 tonnes per square metre. To prevent the panes being pressed together, small supports or spacers must be incorporated at regular intervals in the barely 1 mm cavity. With the support of the BMWi, German partners from the realm of research and industry recently developed an alternative concept for the edge fixing with vacuum insulation glazing, as a result of which large-scale, cost-effective technical production is almost within reach. This concept foresees the use of layers of metal foil, which are applied to the panes of glass in a cold soldering process that avoids damaging the sensitive low-E layers.

Contour Crafting e. betoonist prinditavad majad

Taavi @ 18.09.2010 22:36 | Registreerunud: 01.04.2003

Contour Crafting is a construction process under development by Behrokh Khoshnevis of the University of Southern California's Information Sciences Institute (in the Viterbi School of Engineering) that uses a computer-controlled crane or gantry to build edifices rapidly and efficiently without manual labor. It was originally conceived as a method to construct molds for industrial parts. Khoshnevis decided to adapt the technology for rapid home construction as a way to rebuild after natural disasters, like the devastating earthquakes that have plagued his native Iran.
