Passive Solar and Super Insulated Structures

The period between 1940 and 1970 saw the construction of buildings with extremely poor energy efficiency in the United States. Since the oil crisis of the 70s, the nation has been slowly turning back to energy conservation. Among energy-efficient construction methods currently in use in this country are passive solar, super insulation, earth sheltering, adobe, and cordwood. In the future bio shelters may serve as homes.

Passive solar features are elements of building design that directly utilise Sun and Shade to achieve heating, cooling, or lighting. Such passive elements include a southern orientation, overhangs, deciduous trees to shut out sun in the summer and admit it in the winter, thick walls and floors, and attached solar greenhouses. Most can be incorporated into buildings during their siting and construction at no cost or a modest cost that is recoverable through energy savings.

A particularly promising energy saving technique is super insulation: doubling the normal insulation and adding an airtight barrier. Super insulation may be combined with passive solar features. Usually, super insulated homes use window glazing that admits light, but prevents heat loss. Ventilation is provided by air to air heat exchangers.

Underground structures benefit from the fact that below the frost line the earth remains a relatively stable 54°F. They also offer such advantages as low maintenance, protection from natural and man-made disasters, and conservation of above ground space.

One of the most striking underground complex is built in this country is that 10 L of rooms, passages, and gardens at Fresno, California, that Baldasare Forestiere dug out alone, using only hand tools over 40 years.

Structural Insulated Panels Help Contractors Meet Challenges of Difficult Building Environments

Most construction professionals are familiar with the "Project Management Triangle," a concept that ties cost, schedule, scope and quality together. Impact any of these project elements, and you impact the others. Academics frequently present the triangle as an inflexible set of constraints. Nonsense.

Structural Insulated Panels and Connection Design For Steel Structures

Structural insulated panels are a combination of building materials. They consist of a sandwich of two layers of structural board with a layer of foam insulation between the two. The Committee may sheet or Oriented Strand Board and the foam either expanded polystyrene foam, extruded polystyrene or rigid polyurethane foam. Structural Insulated Panels have become a widely used alternative construction material for homes and other buildings now a day.

The fundamental design concept for SIPs is pleasing to the eye in its simplicity, and offers several advantages for constructing walls and roofs. SIPs provide better overall air tightness and practical thermal performance than conventionally framed walls.

Structural insulated panels provides much higher resistance value than the traditional wood frame homes built in the past and that will result in significant savings over the course of the year for the family living. The construction using structural insulated panels is very straight forward. There is a learning curve involved in it and is still easier for building homes using familiar methods.

Connection design for steel structures:

Connection design is an important aspect in the design of steel structures that is often overlooked by structural engineers and detailers because of lots of requirements in connection design. Information on connection for non-seismic steel structures will be presented in a way that will be useful to engineers and detailers.

The type and amount of information that is required to properly specify the connection design for a structural steel project can be quite complex depending on the type of structure being built. The current design method for steel structure connection is traditional for two reasons. First, the connection capacity is calculated based on an elastic analysis and second, the additional strength of the portion of the tension is not accounted for connection design.

There are lots of connection designs services providers available in market today and they are providing these services at affordable rates. So, outsourcing is the best option available for structural insulated panels design and connection design for steel structure.
