We are looking for a sales executive for better sales flow and customer experience.
OTM Solutions Pte Ltd was founded in 2013, with the following two operations:
Optical & thermal testing laboratory: we provide third-party material testing services to the building & construction industry (e.g. architectural glass optical properties, insulation material thermal conductivity). Our lab is SAC-SINGLAS accredited and with customers from more than 20 countries.
Instrumentation services: we are also the distributor of a well-established instrument manufacturer. We supply measurement instruments (e.g. weather stations and data loggers) and provide integration and measurement services.

We are pleased to introduce our online luminance contrast calculator (V1.0.0, first version). Click the screenshot below to access this online calculator.
The calculation principle of this calculator is similar to the online total daylight calculator. The luminous reflectances of the two sRGB colors selected are calculated with color space conversion. The luminance contrast is then calculated from the two luminous reflectance results.
We are pleased to introduce our online total daylight reflectance calculator (V1.0.0, first version). Click the screenshot below to access this online calculator.
The calculator simply converts an sRGB color (common in screen displays and websites) to a CIEXYZ color, whose Y component is equivalent to the total daylight reflectance of the color (refer to this Wikipedia article for more details).
This calculator calculates total daylight reflectance only and it cannot calculate diffuse and specular daylight reflectances, as the latter two components are dependent on surface finishing, but not on surface color.
The conversion is a theoretical conversion and does not introduce conversion errors. In practice, one needs to manually match a physical color with screen displayed color. This manual process introduces some errors. Nevertheless, this online tools is still useful in estimating the total daylight reflectance of color samples.
20% total daylight reflectance
BCA requires that, for roof surfaces with greater than 20° inclination angle, the total daylight reflectance shall be less than 20% (What is daylight reflectance?). The table below lists 4 colors (grey, red, green, and blue) with close to 20% total daylight reflectance.
If your color is brighter than the 4 colors (except blue color, read the explanation below the table), it is possible that it cannot meet the 20% requirement.
Total daylight reflectance
RGB (123, 123, 123) Hex (#7B7B7B)
RGB (248, 0, 0) Hex (#F80000)
RGB (0, 144, 0) Hex (#009000)
RGB (0, 0, 255) Hex (#0000FF)
Human eyes are less sensitive to blue and red colors, but more sensitive to green and grey colors. In the table above, the total daylight reflectance of the most saturated blue color in the sRGB color space is only with 7.2% of total daylight reflectance.
A measurement system was integrated by OTM for on-site glass optical & thermal property monitoring. The system uses off-shelf sensors and wireless data loggers and can be easily deployed for 24×7 glass performance monitoring projects.
The system consists of two indoor measurement systems (reference room vs. test room) and one outdoor measurement system. Shown below are the system schematics.
The following quantities are measured:
Indoor side (4 quantities): daylight illuminance [lux], solar irradiance [W/m2], air temperature [°C] and glass surface temperature [°C]
Outdoor side (3 quantities): daylight illuminance [lux], solar irradiance [W/m2], air temperature [°C]
However, it is not possible to quantitatively evaluate glass optical & thermal properties rated under standard conditions (e.g. visible light transmittance, U-value, and shading coefficient) from the monitoring results. If such quantities are required, please consider our laboratory glass testing service.
The following instruments from Delta Ohm were used in the monitoring system:
Necessary mounting accessories were included. The instruments can be conveniently installed on-site in less than 1 hour. Shown below is a photo of the outdoor side instruments in the demo installation.
Shown below is a screen capture of some monitoring results (in the wireless data logger control software).
An in-house software can be used to automate the data processing part, as shown below.
