Abstract
The value of a house depends not only on the quality of the construction elements but also on the functionality of its installations. Making mistakes during the design and even execution phases of installations in newly built homes is common. This paper determines, catalogues, and quantifies faults in electrical and telecommunications installations in dwellings based on owners’ complaints and using the ‘learning from faults’ philosophy. To this end, 154 complaints concerning these installations in all of Spain were analyzed and protocolized. The results show that, in all types of dwellings, the most common fault was ‘alterations and malfunctions’ (81%), followed by ‘incorrect or lack of placement of elements’ (14%). The pathological origin with the greatest presence in the research was ‘shortcomings and omissions in the installation’ (40%) and ‘anomalies in the installation’ (36%). Moreover, all functional deterioration processes as well as the type of dwelling where each of these parameters occurred most were defined and quantified (association between each fault and its cause). Finally, the ‘probability factor’ (PF) was determined, which numerically quantifies the probable existence of complaints according to four ranges. The results will pave the way for more precise inspections during the construction phase.
Highlights
The electrical facility of a dwelling is composed of all of the interior elements used for supply, control, and distribution of electricity from the general connection to each of the internal power take-offs and lighting, such as circuit breakers, thermal-magnetic circuit breakers, switches, and plugs [1]
The balance of complaints is uneven between the two domestic facilities
Faults in electricity and telecommunications facilities in dwellings have been studied based on the complaints made by their owners
Summary
The electrical facility of a dwelling is composed of all of the interior elements used for supply, control, and distribution of electricity from the general connection to each of the internal power take-offs and lighting, such as circuit breakers, thermal-magnetic circuit breakers, switches, and plugs [1]. A series of installations (electricity, gas, fire, potable water, sewage, rain, and ventilation) play a vital role and, as such, must be optimized when designing a building, since without them, the building would not operate correctly [3]. Making mistakes during both the design and execution phases in building installations is common. They estimated service lives of various architectural elements of buildings and electromechanical installations
