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."

Occupied:

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.

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).

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.

About Devon Energy Center

Devon Energy Center creates a focal point for the company and Oklahoma City by integrating civic-scaled spaces as a vital component of its overall development. It consolidates Devon’s Oklahoma City–based workforce into a single state-of-the-art facility with numerous amenities.

The three-sided tower evolved in part from Devon’s desire to not “turn its back” on any part of the city. Its orientation and placement provide southern exposure to the park while minimizing solar gain. Its form resulted in highly efficient tripartite floor plates averaging 28,000 square feet that accommodate up to 12 full-corner offices. Responsive to the theme of a “right to light” for all occupants, the 10-foot floor-to-ceiling glazing allows daylight deep into the Tower as well as expansive views. All perimeter offices have floor-to-ceiling glass to maximize daylight. The curtain wall consists of continuous high-performance clear glass with a low-E coating that maximizes daylight, while also reducing heat gain.

With a highly articulated structure, the Rotunda is a grand civic-scaled space with glass walls, a series of balconies, and sky-lit roof. It regularly serves as a venue for special events. Unifying the entire complex within the city, the jewel-like Rotunda symbolically and literally connects the cardinal directions, punctuating the urban axis of Harvey Street. The Rotunda provides 12,522 square feet (1,163 square meters) of welcome assembly space and has hosted fund-raisers, holiday balls, corporate dinners, and civic gatherings.

The Podium contains training and meeting spaces as well as visitor and occupant services. A promenade extending its length creates a glazed day-lit interior corridor. At street level, it provides public access to various amenities, including restaurants, and includes a series of indoor seating areas for dining and overlooking the park.

Defining an urban edge, the Auditorium is a prominent, but intimately scaled, multi-use venue for both corporate and public events. Although nestled into the landscaped park, its strong presence activates street life and supports the downtown’s vitality, while providing dramatic views of downtown and Myriad Botanical Gardens.

The building is among the largest LEED-NC Gold-certified buildings worldwide. The chosen site has direct access to public transit. Construction of the building minimally impacted the natural environment by diverting 68,000 tons (61,669 metric tons) of waste and concrete from landfills and recycling 100 percent of a demolished parking deck on the site. The building also performs well operationally. Potable water consumption is reduced by 50 percent through landscape design and irrigation; overall water use is reduced by 40 percent. Energy use is modulated by district cooling with on-site co-generation, personal comfort control for 50 percent of occupants and personal lighting control for 90 percent of occupants.
