Why Go Green?
As the earth’s climate changes with the depletion of the ozone layer, countries and manufacturers are working towards a greener environment.

The depletion of the ozone layer is mainly caused by halogen atoms which arise from man-made ozone-depleting substances like halocarbons refrigerants, solvents, propellants and foam blowing agents (CFCs, HCFCs, freons and halons). Refrigerant which is used in air-conditioning systems, automotive, food production, food storage and many other industries is one of the major contributors of the depleting ozone layer.

Depletion of the ozone layer allows harmful UVB rays to enter earth’s atmosphere resulting in global warming which will lead to severe climate changes, extreme weathers and changes in agricultural productivity.

Besides producing greener products, construction of green buildings can also greatly reduce the use of air-conditioning, hence making it more energy efficient. Architects can also design buildings to use natural light for indoor spaces. In addition, carefully selecting color shades to help reflect light, also reduces the use of internal lighting. With thoughtful design, internal open spaces can be cooled and lighted up efficiently to reduce or limit the use of air-conditioning and electrical energy.

How To Go Green
With today’s advancement in software and measurement technologies, architects can use color and light measuring instruments to help create virtual green designs. Using color data of building materials and lighting data like luminance and illuminance, architects are able to design buildings that are more energy efficient and kind to the environment.

Instrumentation
For color measurements, instruments such as the portable spectrophotometers and chroma meters are used to study the different shades of color. This is to determine the color effects on light absorption as well as its reflective properties. This information will help the architects understand the properties better.

For lighting measurements, instruments such as luminance and illuminance meters are used to collect lighting data. This data aids the analysis of lightings and how to use them more effectively to light up spaces.

With advancements in CAD CAM designs and easy to use light and color measurement technologies, architects are able to visualize their design in greater details leading to better designed green buildings, so as to reduce our carbon footprint.
