Glossary
ASHRAE - The American Society of Heating, Refrigerating and Air-Conditioning Engineers is an international organization committed to advancing heating, ventilation, air conditioning and refrigeration to serve humanity and promote a sustainable world through research, standards writing, publishing and continuing education. ASHRAE 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, has become the basis for building codes and the standard for building design and construction related to energy efficiency and methods of determining compliance. (www.ashrae.org)

Black Body– A theoretical object that absorbs all radiation incumbent upon it, turning it into heat. Conversely, it must also emit radiation at the maximum possible intensity for a given temperature.

Cool Roof – A cool roof reflects and emits the sun's heat back to the sky instead of transferring it to the building below. "Coolness" is measured by two properties, solar reflectance and thermal emittance. Both properties are measured from 0 to 1 and the higher the value, the "cooler" the roof. (www.coolroofs.org)

Energy Modeling – A computer model used to analyze a building's energy systems in order to project its possible consumption rate. (www.egreenideas.com/glossary.php)

Green Globes™ – The Green Building Initiative introduced the Green Globes, which were developed in Canada, to the U.S. construction market. The Green Globes program is an online, questionnaire-based green buildings rating system.

Heat Island Effect – The increase in ambient temperature that occurs over large paved areas compared to natural landscape. (www.egreenideas.com/glossary.php)

LEED® – Leadership in Energy and Environmental Design is a consensus-based rating program of the US Green Building Council, an independent, non-government organization. LEED is used to certify green buildings based on defined performance levels.

Insulated Metal Panel – A roof or wall panel composed of inner and outer metal skins that encapsulate an insulating core, usually made of rigid plastic foam.
Top of Page
Light Transmitting Panels – A translucent roof or wall panel, typically made of reinforced acrylic plastic that can be used as a method of allowing natural light into an enclosed space.
Top of Page
Load – A source or drain of heat that affects the design of the Heating, Ventilation and Air Conditioning (HVAC) systems in a building. Loads may be from internal sources, such as persons or equipment, or from the external environment.
Top of Page
Low-Emitting Materials – Materials, usually used as adhesives, sealants, or coatings, that can be shown to emit a relatively low amount of Volatile Organic Compounds (VOC) through some definitive criterion or test.
Top of Page
Mill Test Report – Documentation supplied by a producer of a steel product that certifies the chemical composition and mechanical test results required by a material specification, such as the American Society of Testing and Materials (ASTM).
Top of Page
Solar Reflectance – Sometimes referred to as reflectivity or albedo, solar reflectance is a value between 0 and 1 that represents the fraction of incumbent energy reflected by a body or surface. Reflectivity is determined by ASTM C1549, E903 or E1918.
Top of Page
Solar Reflective Index – SRI is an alternative method for considering the radiative properties of roofing materials. SRI is defined by ASTM Standard E1980-01 and is a calculation that uses solar reflectance and thermal emittance. EPA summarizes SRI as "the relative steady-state surface temperature with respect to the standard white (SRI=100) and standard black (SRI=0) under the standard solar and ambient conditions. (www.coolroofs.org)
Top of Page
Thermal Emittance – Sometimes referred to as emissivity, thermal emittance is a value between 0 and 1 that represents the energy radiated from an object relative to a black body at the same temperature. Emittance is determined by ASTM C1371 or E408.
Top of Page
USGBC – The U.S. Green Building Council is a private (non-government), non-profit community of leaders working to make green buildings available to everyone. They certify green buildings for Leadership in Energy and Environmental Design (LEED), offer licensing and professional development through local organizations, and publish reference and research materials.

Valley gutters – Specially designed gutters, usually located in a roof valley or behind a parapet or mansard that allow rainwater to drain from a roof surface.

LEED - Point Chart
This chart presents some of the ways NCI Metal Building products can help you earn points toward LEED Certification.
LEED®-NC Metal Building Credit Guide |
| Name |
Description |
Number of Points |
Reason |
| SS Credit 5.1 |
Site Development:
Protect or Restore Habitat |
1 |
Being shop fabricated, NCI metal buildings allow field assembly using a minimal work area. |
| SS Credit 7.1 |
Heat Island Effect:
Non-roof |
Up to 2 (1 plus 1 Exemplary Performance point) |
By deploying parking covers with NCI roof products, 1 point is earned for 50% of spaces covered, and an exemplary performance point can be earned for 100% of spaces covered. |
| SS Credit 7.2 |
Heat Island Effect:
Roof |
1 |
Our Snow White, Ivory, Bone White, and Solar White colors meet the low-slope requirement and all NCI colors meet the steep slope requirement of this credit. |
| EA Credit 1 |
Optimize Energy Performance |
Up to 10 |
By utilizing NCI cool roof colors and insulated metal panels in your energy models, you can reduce external loads and downsize HVAC equipment to help get the most points possible. |
| MR Credit 4.1 and MR Credit 4.2 |
Recycled Content: 10% and 20% |
Up to 2 |
Depending on the nature of the project, NCI metal buildings will contain between 25% and 60% recycled steel by weight. (Post-consumer + ½ Pre-consumer) On a typical project, this will represent about 40% of our contract value. |
| MR Credit 5.1 (under LEED-NC 2.0 and 2.1 only) |
Regional Materials : 20% Manufactured Regionally |
1 |
NCI is comprised of a network of companies operating 39 manufacturing facilities across the United States and Mexico. This network maximizes the amount of material manufactured within a 500 mile radius of most points in the US. |
| EQ Credit 8.1 |
Daylight and Views:Daylight 75% of spaces |
1 |
NCI's insulated light transmitting panels are excellent diffusers when utilized on the roof or walls. |
