Goa: Power saving more important than lowest bids


PANAJI : Policymakers need to understand and adopt sustainable lighting practices instead of pushing for illumination changes due to an industry drive or based on power consumption, said organisers of ‘Lights of Goa ’, a seminar on efficient lighting. “Government agencies taking tenders need to be asked whether design is really considered an important aspect in lighting contracts or is it just the commercial aspect that’s considered?” said architectural lighting design consultant Kapil Surlakar. Referring to the current practice of awarding lighting tenders to the lowest bidder, he said that when lighting of streets or institutions is taken up, power saving efficiency and lowest prices are often the sole consideration. “Human beings are totally driven by light and it is very important for policy makers to understand that light can have far reaching consequences. Looking at the lowest cost may not give you the most appropriate light. It is not the right way,” he said. Surlakar was speaking on the sidelines of the international architectural lighting seminar that was held in Goa. The participants expressed concern over the inefficient illumination fixtures being used by government departments and institutions, which could in turn have a negative impact on human sleep cycles. “There was a campaign a few years back where LED was being forced down everybody’s throats. What one needs to understand is that if people blindly accept all this technology, then one will not be able to achieve a correct lighting system,” said Sacheen Pai Raikar, one of the seminar organisers. He pointed out that bulbs which emit light that falls in the blue spectrum can disrupt the sleep cycle. “Blue light at night can throw off the circadian rhythm of birds and humans, affecting the sleep cycle. Nobody seems sensitive to these things,” Raikar said. Participants expressed concern over inefficient illumination fixtures used by the government and institutions which could have a negative impact on human sleep cycles.
