@CO2 emissions originating from energy consumption in house holds and tertiary industries accounts for about one thirds of Japan’s total CO2 emissions. More over, measures to reduce electricity consumption in the housing and buildings sector are an urgent agenda together with counter-measures against tight electricity power supply in the aftermath of the Great Earthquake in East Japan.
@ Among other things, measures for lightning energy reduction in houses and buildings are important and have major positive effects. This is because lightning, the consumption of electricity in lightning represents a large part of the total electricity consumption of buildings and the reduction of electricity consumption in lightning with its heat generation control effects leads to reduction of electricity consumption for air-conditioning. Viewed in this light, it can be rightly said that what is needed is a comprehensive lightning electricity consumption reduction strategy by means of an innovative and imaginative system covering light source,@peripheral devices & equipment and lightning method
@ Especially, to enhance efficiency of lightning by way of using reflectors and diffusers is an inexpensive measure that can be relatively easily implemented and can be widely introduced in buildings and houses.
@For these reasons, a verification project is being implemented with lightening energy reduction technology (reflectors and diffusers, etc.), one of the technology fields for counter-measures against global warming as a target technology field for verification

(Lightening Energy Reduction Technology: Reflectors and Diffusers, etc.)
@The target technologies for verification shall have the objective of “energy consumption reduction required for materializing the lightning environment to be sought in@daily operations or daily life ” , which are the following technologies
- EReflectors…
- Technology installed around light source, which enables the ratio of the luminous light shed from the light source reaching the object of lightning to be increased or enables illuminance distribution to be adjusted, by enabling the luminous light shed from light source to be effectively and efficiently reflected.
- EDiffusers…
- Technology installed around the light source, which enables illuminance distribution to be adjusted, by enabling the luminous light to be effectively and efficiently diffused.
| Technology | Reference case (Reference) | Technology to be compared (Before) | Target technology for verification (After) |
| Reflector fluorescent light conceived as light source |  Light sourceithe lower luminous light alone measured by ensuring the condition of a reflection rate of 0% |
