Many Leeds credits come standard with a pre-engineered/pre-fabricated steel building. The entire process of producing a pre-engineered steel building has been refined and developed to be as energy efficient as possible. Using recycled material, extensive design processes, regional production and shipping locations, the energy required to design, manufacture, ship and erect a pre-engineered steel building makes it one of the most efficient buildings available.

The raw material used to fabricate the primary structure in our steel buildings is almost all recycled steel saving on the energy intensive process of creating steel. While keeping the costs of our buildings down, it also keeps this scrap material out of the land fill.

Some paint finishes will conform to the requirements for these leeds points. All sealants and adhesives used on the building must conform to the leedrequirements as well; VOC (volatile organic content) must be 250grams/liter or lower.

MINIMIZE REQUIRED MATERIAL:
Using extensive analysis, design, and computer modeling our pre-engineered steel buildings minimize the amount of steel required and shop time needed to fabricate the building so material isn’t wasted and the shop processes minimize their effect on our environment. This precise design process results in the lightest possible structure saving on the size and amount of concrete, of the foundations that will support the steel structure.

In the same way we use scrap steel to fabricate our steel buildings, our buildings can be re-used, relocated, or savage for recycling. Practically 100% of our steel buildings can be re-used in one of these ways.
With warranties of 25 years and minimal maintenance requirements, the life span of a steel building surpasses any other structural building material.
DAYLIGHT AND VIEWS-DAYLIGHT:
With the integration of translucent, or opaque fibre-glass light panels ot the roof and walls, our metal buildings can qualify for this leed credit which requires 25 footcandles of natural light to 75% of the regularly occupied space.
The wall and roof assemblies in a pre-engineered steel building are versatile and can be made to meet any insulation requirements. Using thermal spacers, batt insulation, rigid insulation or sandwich panels, the thermal values of a pre-engineered steel building can far exceed new requirements set out by the building code for thermal values and green building requirements.
