A method for controlling lighting, said method comprising the steps of: selecting, on the basis of a predetermined criterion, a particular group among a plurality of groups of color of light, said color of light having been categorized into groups on the basis of dominant wavelength, where each group of colors is arranged to influence the thermoregulation of a vertebrate in a particular manner; generating a control signal for controlling the dominant wavelength of light emitted from at least one light source in accordance with the selected group of colors; and transmitting the generated control signal to said at least one light source for said at least one light source to emit light of the selected group of colors, thereby influencing the thermoregulation of a vertebrate being exposed to the light of the selected group of colors emitted by said at least one light source on the basis of said predetermined criterion; and communicating the control signal to a climate control device configured to control a climate control system, the control signal indicating whether to lower or increase the output temperature of the climate control system depending on the selected group of colors; wherein the control signal indicates that: the output temperature of the climate control system shall be lowered when the predetermined criterion is to lower heating energy consumption in the climate control system, for which criterion a group of colors having a dominant wavelength in the range of approximately 576-700 nm is selected; or the output temperature of the climate control system shall be increased when the predetermined criterion is to lower cooling energy consumption in the climate control system, for which criterion a group of colors having a dominant wavelength in the range of approximately 460-520 nm is selected. selecting, on the basis of a predetermined criterion, a particular group among a plurality of groups of color of light, said color of light having been categorized into groups on the basis of dominant wavelength, where each group of colors is arranged to influence the thermoregulation of a vertebrate in a particular manner; generating a control signal for controlling the dominant wavelength of light emitted from at least one light source in accordance with the selected group of colors; and transmitting the generated control signal to said at least one light source for said at least one light source to emit light of the selected group of colors, thereby influencing the thermoregulation of a vertebrate being exposed to the light of the selected group of colors emitted by said at least one light source on the basis of said predetermined criterion; and communicating the control signal to a climate control device configured to control a climate control system, the control signal indicating whether to lower or increase the output temperature of the climate control system depending on the selected group of colors; wherein the control signal indicates that: the output temperature of the climate control system shall be lowered when the predetermined criterion is to lower heating energy consumption in the climate control system, for which criterion a group of colors having a dominant wavelength in the range of approximately 576-700 nm is selected; or the output temperature of the climate control system shall be increased when the predetermined criterion is to lower cooling energy consumption in the climate control system, for which criterion a group of colors having a dominant wavelength in the range of approximately 460-520 nm is selected. the output temperature of the climate control system shall be lowered when the predetermined criterion is to lower heating energy consumption in the climate control system, for which criterion a group of colors having a dominant wavelength in the range of approximately 576-700 nm is selected; or the output temperature of the climate control system shall be increased when the predetermined criterion is to lower cooling energy consumption in the climate control system, for which criterion a group of colors having a dominant wavelength in the range of approximately 460-520 nm is selected.
