Architectural engineering, also known as building engineering or architecture engineering, is an engineering discipline that deals with the technological aspects and multi-disciplinary approach to planning, design, construction and operation of buildings, such as analysis and integrated design of environmental systems (energy conservation, HVAC, plumbing, lighting, fire protection, acoustics, vertical and horizontal transportation), structural systems, behavior and properties of building components and materials, and construction management.
From reduction of greenhouse gas emissions to the construction of resilient buildings, architectural engineers are at the forefront of addressing several major challenges of the 21st century. They apply the latest scientific knowledge and technologies to the design of buildings. Architectural engineering as a relatively new licensed profession emerged in the 20th century as a result of the rapid technological developments. Architectural engineers are at the forefront of two major historical opportunities that today's world is immersed in: (1) that of rapidly advancing computer-technology, and (2) the parallel revolution arising from the need to create a sustainable planet.
Related engineering and design fields
Structural engineering involves the analysis and design of the built environment (buildings, bridges, equipment supports, towers and walls). Those concentrating on buildings are sometimes informally referred to as "building engineers". Structural engineers require expertise in strength of materials, structural analysis, and in predicting structural load such as from weight of the building, occupants and contents, and extreme events such as wind, rain, ice, and seismic design of structures which is referred to as earthquake engineering. Architectural Engineers sometimes incorporate structural as one aspect of their designs; the structural discipline when practiced as a specialty works closely with architects and other engineering specialists.
Mechanical, Electrical and Plumbing (MEP)
Mechanical engineering and electrical engineering engineers are specialists, commonly referred to as (Mechanical, Electrical and Plumbing) when engaged in the building design fields. Also known as "building services engineering" in the United Kingdom, Canada and Australia. Mechanical engineers often design and oversee the heating, ventilation and air conditioning (HVAC), plumbing, and rainwater systems. Plumbing designers often include design specifications for simple active fire protection systems, but for more complicated projects, fire protection engineers are often separately retained. Electrical engineers are responsible for the building's power distribution, telecommunication, fire alarm, signalization, lightning protection and control systems, as well as lighting systems
The architectural engineer (PE) in the United States
In many jurisdictions of the United States, the architectural engineer is a licensed engineering professional. Usually a graduate of an EAC/ABET-accredited architectural engineering university program preparing students to perform whole-building design in competition with architect-engineer teams; or for practice in one of structural, mechanical or electrical fields of building design, but with an appreciation of integrated architectural requirements.
Formal architectural engineering education, following the engineering model of earlier disciplines, developed in the late 19th century, and became widespread in the United States by the mid-20th century. With the establishment of a specific "architectural engineering" NCEES Professional Engineering registration examination in the 1990s, and first offering in April 2003, architectural engineering became recognized as a distinct engineering discipline in the United States.
In most license-regulated jurisdictions, architectural engineers are not entitled to practice architecture unless they are also licensed as architects. Practice of structural engineering in high-risk locations, e.g., due to strong earthquakes, or on specific types of higher importance buildings such as hospitals, may require separate licensing as well. Regulations and customary practice vary widely by state or city.
The architect as architectural engineer
In some countries, the practice of architecture includes planning, designing and overseeing the building's construction, and architecture, as a profession providing architectural services, is referred to as "architectural engineering". In Japan, a "first-class architect" plays the dual role of architect and building engineer, although the services of a licensed "structural design first-class architect"(構造設計一級建築士) are required for buildings over a certain scale.
In some languages, such as Korean and Arabic, "architect" is literally translated as "architectural engineer". In some countries, an "architectural engineer" (such as the ingegnere edile in Italy) is entitled to practice architecture and is often referred to as an architect. These individuals are often also structural engineers. In other countries, such as Germany, Austria, Iran, and most of the Arab countries, architecture graduates receive an engineering degree (Dipl.-Ing. – Diplom-Ingenieur).
In Brazil, architects and engineers used to share the same accreditation process (Conselho Federal de Engenheiros, Arquitetos e Agrônomos (CONFEA) – Federal Council of Engineering, Architecture and Agronomy). Now the Brazilian architects and urbanists have their own accreditation process (CAU – Architecture and Urbanism Council). Besides traditional architecture design training, Brazilian architecture courses also offer complementary training in engineering disciplines such as structural, electrical, hydraulic and mechanical engineering. After graduation, architects focus in architectural planning, yet they can be responsible to the whole building, when it concerns to small buildings (except in electric wiring, where the architect autonomy is limited to systems up to 30kVA, and it has to be done by an Electrical Engineer), applied to buildings, urban environment, built cultural heritage, landscape planning, interiorscape planning and regional planning.
In Greece licensed architectural engineers are graduates from architecture faculties that belong to the Polytechnic University, obtaining an "Engineering Diploma". They graduate after 5 years of studies and are fully entitled architects once they become members of the Technical Chamber of Greece (TEE – Τεχνικό Επιμελητήριο Ελλάδος). The Technical Chamber of Greece has more than 100,000 members encompassing all the engineering disciplines as well as architecture. A prerequisite for being a member is to be licensed as a qualified engineer or architect and to be a graduate of an engineering and architecture schools of a Greek university, or of an equivalent school from abroad. The Technical Chamber of Greece is the authorized body to provide work licenses to engineers of all disciplines as well as architects, graduated in Greece or abroad. The license is awarded after examinations. The examinations take place three to four times a year. The Engineering Diploma equals a master's degree in ECTS units (300) according to the Bologna Accords.
The architectural, structural, mechanical and electrical engineering branches each have well established educational requirements that are usually fulfilled by completion of a university program.
Architectural engineering as a single integrated field of study
Its multi-disciplinary engineering approach is what differentiates architectural engineering from architecture (the field of the architect): which is an integrated, separate and single, field of study when compared to other engineering disciplines.
Through training in and appreciation of architecture, the field seeks integration of building systems within its overall building design. Architectural engineering includes the design of building systems including heating, ventilation and air conditioning (HVAC), plumbing, fire protection, electrical, lighting, architectural acoustics, and structural systems. In some university programs, students are required to concentrate on one of the systems; in others, they can receive a generalist architectural or building engineering degree.
