  • Facts
Height 78.0 m / 256 ft
Please note that this height is estimated, based on a floor count of 18 floors. The estimation has been arrived at by analyzing 5,962 other buildings of the same office function on this database that do have confirmed heights. The user should be aware that non-standard features, such as significant spires or raised entrances / podiums, may affect the accuracy of this estimation.

EGWW Federal Building

Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

Structural Material
Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

Height
Please note that this height is estimated, based on a floor count of 18 floors. The estimation has been arrived at by analyzing 5,962 other buildings of the same office function on this database that do have confirmed heights. The user should be aware that non-standard features, such as significant spires or raised entrances / podiums, may affect the accuracy of this estimation.
Architectural
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

78.0 m / 256 ft

Floors Above Ground
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Floors Below Ground
The number of floors below ground should include all major floors located below the ground floor level.

# of Parking Spaces
Number of Parking Spaces refers to the total number of car parking spaces contained within a particular building.

184

# of Elevators
Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).

Tower GFA
Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

A Model Modernization: Edith Green-Wendell Wyatt Federal Building and GSA’s Mid-Century Inventory

Edith Green-Wendell Wyatt Federal Building (EGWW) is an 18-story federal office designed by Skidmore, Owings & Merrill and constructed in downtown Portland, Oregon, in 1975....

About Edith Green-Wendell Wyatt Federal Building

The Edith Green-Wendell Wyatt (EGWW) Federal Building was an existing 18-story, 512,474 square-foot (47,610 square-meter) office tower, completed in 1974. The building no longer met the functional or the energy and conservation requirements of the contemporary US government, so a major renovation project was undertaken. A mechanical upgrade was paired with a full replacement of the building envelope with a distinctive shading facade, affording better energy performance and a new lease on life.

This project achieves operational sustainability that would be admirable in a brand-new building, let alone a retrofit of a 1970s "energy hog." The building has been transformed from a bunker-like, concrete-encased mass into a trellised volume that seems more lightweight by an order of magnitude, yet affords more floor space than the previous version.
