Energy Of Light

High level of energy consumption for a decades has started to reveal critical environmental problems for the globe.The best part of this issue is addressed to buildings with %40 usage of the whole world energy consumption.In this scope,historical buildings have less energy efficieny solutions that causes this situation,at the same time,beside of economical part,most of the buildings should be maintained since they are historical presevation of monuments and LCA of the total reconstruction or renovataion will also affect the globe.In the project,we tried to contribute to the global challenge by using radiation energy with implementing reflectors.The wall section,lintel and sill of the historical windows have approximately 50cm voided rectangle form gap that provides a zone for reflectors placement.In that way the radiation energy by the sun will be translated to those reflectors after passing trough glazing windows.Thus,radiation energy will be boosted and heat it up the reflectors and scatter the light to interior place more evenly by washing the ceiling.Also,the diffuse light by the ground will be reflected to floor area by touching lintel part.Lastly,the reflectors will have the texture of the sky over the window sill that increases visual aspect.In order for benefiting from this solution,we tried to examine the locations that are either latitude 15 or above of the globe during the colder months.In the experiment when the weather is lower than 21 degree the reflectors turned on by removing roller shutter surface on it and increased the energy gaining according to weather conditions with sunny and cloudy cases.The analysis over the poster were taken in Barcelona in March 21 at 11:30 am,since there are many historical buildings and have sunny and cloudy weather conditions during the colder months.As a result the reflectors placement with roller shutter surface will work two different ways.In winter,it will increase the energy of light and in the summer it will work as solar cooler by emitting the energy of light.
