Mechanical and electrical systems in buildings

Mechanical, electrical and plumbing MEP refers to these aspects of building design and construction. In commercial buildings, these elements are often designed by a specialized engineering firm. MEP specifically encompasses the in-depth design and selection of these systems, as opposed to a tradesperson simply installing equipment.

For example, a plumber may select and install a commercial hot water system based on common practice and regulatory codes. A team of MEP engineers will research the best design according to the principles of engineering, and supply installers with the specifications they develop.

As a result, engineers working in the MEP field must understand a broad range of disciplines, including dynamics, mechanics, fluids, thermodynamics, heat transfer, chemistry, electricity, and computers. As with other aspect of buildings, MEP drafting , design and documentation were traditionally done manually. Computer-aided design has some advantages over this, and often incorporates 3D modeling which is otherwise impractical. Building information modeling provides holistic design and parametric change management of the MEP design.

Maintaining documentation of MEP services may also require the use of a geographical information system or asset management system. Thus, it incorporates the control of environmental factors psychrometrics , either for human comfort or for the operation of machines.

Heating, cooling, ventilation and exhaustion are all key areas to consider in the mechanical planning of a building. For example, Google's data centres make extensive use of heat exchangers to cool their servers. A major concern for people designing HVAC systems is the efficiency, i. Efficiency is optimised by changing the design of the system on both large and small scales.

Heat pumps [7] and evaporative cooling [8] are efficient alternatives to traditional systems, however they may be more expensive or harder to implement.

The job of an MEP engineer is to compare these requirements and choose the most suitable design for the task. Electricians and plumbers usually have little to do with each other, other than keeping services out of each other's way. The introduction of mechanical systems requires the integration of the two so that plumbing may be controlled by electrics and electrics may be serviced by plumbing.

Thus, the mechanical component of MEP unites the three fields. Virtually all modern buildings integrate some form of AC mains electricity for powering domestic and everyday appliances. Such systems typically run between and volts, however their classifications and specifications vary greatly by geographical area see Mains electricity by country.

Mains power is typically distributed through insulated copper wire concealed in the building's subfloor, wall cavities and ceiling cavity. These cables are terminated into sockets mounted to walls, floors or ceilings. Similar techniques are used for lights "luminaires" , however the two services are usually separated into different circuits with different protection devices at the distribution board.

Three-phase power is commonly used for industrial machines, particularly motors and high-load devices. Provision for three-phase power must be considered early in the design stage of a building because it has different regulations to domestic power supplies, and may affect aspects such as cable routes, switchboard location, large external transformers and connection from the street.

Advances in technology and the advent of computer networking have led to the emergence of a new facet of electrical systems incorporating data and telecommunications wiring.

Note that a low voltage system used for telecommunications networking is not the same as a low voltage network. The information technology sector of electrical installations is used for computer networking, telephones, television, security systems, audio distribution, healthcare systems, robotics, and more.

These services are typically installed by different tradespeople to the higher-voltage mains wiring and are often contracted out to very specific trades, e. Regulations on low voltage wiring are often less strict or less important to human safety. As a result, it is more common for this wiring to be installed or serviced by competent amateurs, despite constant attempts from the electrical industry to discourage this.

Competent design of plumbing systems is necessary to prevent conflicts with other trades, and to avoid expensive rework or surplus supplies. Plumbing for HVAC systems involves the transfer of coolant, pressurised air, water, and occasionally other substances. Ducting for air transfer may also be consider plumbing, but is generally installed by different tradespeople.

He would have to reveal his true feelings for her-or admit that he was only doing a job. All this love she felt for him was riding on the answer to an impossibly simple question: Would he stop her. Perhaps it was unwise to force the issue, especially so soon. But then, the choice was bound to come up, for Milt would be calling her back to Seattle any day. She would give them both a graceful exit.

Пуля ударила в закрывающуюся дверь. Пустое пространство зала аэропорта открылось перед Беккером подобно бескрайней пустыне. Ноги несли его с такой быстротой, на какую, казалось ему, он не был способен. Когда он влетел во вращающуюся дверь, прозвучал еще один выстрел. Стеклянная панель обдала его дождем осколков.

Беккер легонько обнял. Девушка высвободилась из его рук, и тут он снова увидел ее локоть. Она проследила за его взглядом, прикованным к синеватой сыпи. - Ужас, правда. Беккер кивнул. - Ты же сказала, что не колешься. Девушка засмеялась: - Это же чудо-маркер.

Его редеющие седые волосы спутались, и даже несмотря на прохладу, создаваемую мощным кондиционером, на лбу у него выступили капельки пота. Его костюм выглядел так, будто он в нем спал. Стратмор сидел за современным письменным столом с двумя клавиатурами и монитором в расположенной сбоку нише. Стол был завален компьютерными распечатками и выглядел каким-то чужеродным в этом задернутом шторами помещении. - Тяжелая неделя? - спросила .

Пользуются ли писсуаром в дамском туалете -неважно, главное, что сэкономили на лишней кабинке. Беккер с отвращением оглядел комнату. Грязь, в раковине мутная коричневатая вода. Повсюду разбросаны грязные бумажные полотенца, лужи воды на полу. Старая электрическая сушилка для рук захватана грязными пальцами. Беккер остановился перед зеркалом и тяжело вздохнул. Обычно лучистые и ясные, сейчас его глаза казались усталыми, тусклыми.

Среди неясных силуэтов впереди он увидел три торчащие косички. Красная, белая и синяя. Я нашел. В его голове смешались мысли о кольце, о самолете Лирджет-60, который ждал его в ангаре, и, разумеется, о Сьюзан. В тот момент, когда он поравнялся с сиденьем, на котором сидела девушка, и подумал, что именно ей скажет, автобус проехал под уличным фонарем, на мгновение осветившим лицо обладателя трехцветной шевелюры.

Само ее существование противоречило основным правилам криптографии. Она посмотрела на шефа. - Вы уничтожите этот алгоритм сразу же после того, как мы с ним познакомимся.

Стратмор нетвердыми шагами двинулся к дрожащему корпусу и упал на колени, как грешник перед лицом рассерженного божества.
