It should also be considered that in addition to the seasonal summer or winter external thermal loads, there are those corresponding to the building's own equipment, that is, loads for general and localized lighting and for energy dissipated by the various current electronic devices such as computers, printers, servers, copiers, etc. which have been multiplied precisely by the new technological and service requirements of the new technological user.

Along with this, the tendency to use large glazed walls (Courtain Walls) increases, which, added to large atriums with glass or translucent roofs, generates an excessive increase in thermal loads due to solar radiation.

That is why it is essential during the building design stage to properly anticipate and select the air conditioning system.

The execution of the ducts to transport and distribute fluids (usually treated air), together with adequate insulation of these throughout the architectural floors; It implies providing spaces for its location and passage. They are usually called plenums") and can be horizontal or vertical and be below the floor or above the ceiling.

The intersection with structures, sanitary service pipes, lighting and/or security devices and their associated network are problems to be resolved that always affect the initial project.

It is necessary to foresee the construction of sound traps to prevent the spread of noise, implementation of access in ceilings to sensors and flow modulation organisms (blinds) for their repair and/or maintenance, laying of electrical wiring for driving force and control, communication links between component elements of the increasingly widespread "Intelligent Control Systems".

Spaces must be created for the correct location of external condensation equipment, expulsion of burned gases, renovation air intakes for inhabited premises, machine rooms of appropriate dimensions, and others that should be analyzed and expressly contemplated in the construction documentation from the very beginning of the preliminary project.

It is the habit of many professionals to underestimate the characteristics of the required installation, or to delimit them very generically in a specification, leaving for the pre-award quotation stage, with the comparison between various technical-economic proposals of possible contractors of the union, the determination of the type and magnitude of the system to be implemented.

The danger that runs with this attitude is that various discrepancies and interferences appear during the construction stage that, since there is not a project that is fully conceived in all its parts from the beginning, will surely cause execution difficulties with the appearance of additional work and consequent variation in work deadlines and costs.

Although in all architecture schools in the world the Architect is given the professional responsibility to plan, dimension and direct IT and others, it is usual for him to delegate it to a Mechanical Engineer or even to an installation tradesman. This attitude relativizes one's own professional responsibility, losing the ability to control what is being executed, without being able to separate the inherent responsibility for each and every part of the work.

This attitude could be attributed to the designer's lack of experience or lack of knowledge of some of the variables involved in this type of installation, but the reality is that in the highly competitive market in which we find ourselves today, with a growing tendency to reduce costs and drastically reduce execution times, while simultaneously maintaining high levels of quality and results, any unpredictability generates interruptions or alterations of the process for which the architects cannot and should not fail to take responsibility.
