The change of luminaires for their LED technology equivalents is the most commonly used measure to obtain savings in consumption, although from the energy point of view it does not correspond to efficient lighting. We design and implement lighting that guarantees light comfort with which to distinguish shapes, colors, appreciate reliefs or moving objects, without causing eye disorders or visual fatigue; avoiding contrasts, glitters and glare.

Except for new or recently renovated building installations and premises, there is normally a combination of diffusers and lamps (incandescent, discharge or fluorescent tubes); whose arrangement prevents obtaining the luminous flux required for each activity.

In addition, poor lighting can cause eye disorders that lead to visual fatigue. Correct lighting is one that, without causing fatigue, allows you to distinguish shapes, colors, appreciate reliefs or moving objects; avoiding, as far as possible, glare and luminances or elevated sensations of clarity within the visual field of a user or worker.

The change of luminaires for their LED technology equivalents is the most commonly used measure to obtain savings in lighting consumption that can reach 80%; as long as the previous usage and hours of operation are maintained. GESTIÓN DE TECNOLOGÍAS Y ENERGÍAS RENOVABLES, S.L. wants to offer added value that justifies the investment required beyond the payback period that such savings entail.

Limiting the energy improvement action to a renewal of lamps according to their power is not efficient from the energy point of view, since it is necessary to check whether the VEEI or energy efficiency value of the resulting installation is lower than the limit values which requires the new CTE DB-HE.

GESTIÓN DE TECNOLOGÍAS Y ENERGÍAS RENOVABLES, S.L. is aware that the lighting required in each dependency is a function of the use and activity carried out there; Point or diffuse lighting, a place with commercial activity, an office or an industrial warehouse is not the same as a manufacturing or storage activity.

In each room GESTIÓN DE TECNOLOGÍAS Y ENERGÍAS RENOVABLES, S.L. study which is the most suitable arrangement of the luminaires according to the required luminous flux; as well as the color temperature; expressed in degrees Kelvin and determined, in turn, by the color rendering index of the light source. The luminaire will emit a colder or warmer light, thereby influencing the perception of colors by the human eye. The luminous efficacy of the light source is also considered, which is the ratio between the luminous flux emitted and the power consumed.

GESTIÓN DE TECNOLOGÍAS Y ENERGÍAS RENOVABLES, S.L. takes into account the presence or not of natural lighting, which in any case is complemented by artificial light, as well as its arrangement with respect to workstations; taking into account that it is subject to strong variations depending on the schedule and weather conditions outside.

Since lighting is the amount of luminous flux that falls on a surface, using a light meter GESTIÓN DE TECNOLOGÍAS Y ENERGÍAS RENOVABLES, S.L. it measures the amount of light that falls on the work plane in lux, to later analyze compliance with the values recommended by the UNE12464.1 standard; as well as compliance with the minimum values required by the DB-SUA of the CTE to obtain an average uniformity relative to the amount of light and avoid dazzling risks, measured by the unified glare index or UGR, which depends on the type of luminaire and its proper distribution.

In case of detecting any breach, after carrying out the corresponding light study, GESTIÓN DE TECNOLOGÍAS Y ENERGÍAS RENOVABLES, S.L. I would propose not only a renovation of the luminaires to reduce the energy cost but also a new distribution that ensures a sufficient level of lighting, without contrasts or excessive brightness, avoiding glare, ensuring the light comfort of the workers and users of each room with compliance of the values required by the applicable regulations.
