About Us

We are a consulting and diagnostic company, independent from manufacturers and suppliers. We serve only one master: YOU. We offer our remote services such as computer simulations, and drawing reviews worldwide, including China (e.g., Wuhan, Shenzen, Shanghai, Kunming), Middle East, and Africa. More about us.

Computer Modeling and Simulations

We assist designers and attorneys in analyses and presentations of physical processes before or after these processes occurred in buildings. We offer a variety of computer simulations addressing various asspects of building performance, such as thermal, moisture, optical, solar, daylight, acoustic, and air (wind) movement.

We are recognized as a world-class leader in the field of 3-dimensional computer simulations. Many of these state-of-the-art services are unique worldwide. We are a direct provider, which explains why our prices are low and quality is high. Feel free to add a markup if you are a re-seller.

Spectrophotometric Simulations

Glass is seldom matched properly, as seen on the photos below, and therefore owners often require a blanket glass replacement, after only few pieces have been broken or scratched.

Save hundreds of thousands of dollars which would otherwise be spent on replacement of the intact old glass not matching the new replacement glass.

This analysis is performed to find the closest visual match for architectural glass: either designed or existing on facades. Also used for verification of an unknown glass. We compare it with the current largest glass database in the world. Also, our lab owns a spectophotometer, which we use to verify properties of glass samples collected in the field and received from other parties. The diagnostic laboratory and field services are described here.

Daylight and Illumination Studies

Would it be too dark in the working spaces? Would prison guards be blinded by glare from windows precisely when inmates are out?

We never loose the primary function of glazing from sight: letting the natural light in.We perform daylight simulations and illumination studies to verify the daylight factor. Particularly useful in verification of compliance with the LEED credit 8.1 requirement.

Solar Heat Gain and Shading Studies

How much energy can you save by adding exterior shading? What would be the return on investment on a better window? How about adding a shaded patio? Wouldn't it get too dark inside? The only way to find out is to simulate these alternatives ahead of time, because the same component would perform differently in different buildings.

These analysis are performed for identififcation of comparative energy impact of individual components of a building.

Whole Building Energy Modeling Performed for the comparative analysis of design trade-offs to meet the predefined energy goals. Also, it's an important part of the energy rating process, particularly whencombined with the air tightness verification in the field. arting at $.

2-Dimensional Steady State Thermal Analysis Performed on simple assemblies to identify the thermal transmittance (U value) and assess the condensation risk. These NFRC-compliant simulations are nationally accepted as an alternative of the expensive laboratory testing of fenestration. Also, this analysis yield SHGC of the fenestration.

3-Dimensional Steady State Thermal Analysis Performed chiefly to assess the condensation risk of those details that escape the 2D representation, such as shading brackets, anchors, and framing interstections. Invaluable in verification of impact of thermal bridging caused by components penetrating the heat-control layer in two directions.


Sample 3-Dimensional Steady State Thermal Analysis, revealing the thermal irregularities at the skylight rafter. Would the water condensing underside the glass be drained safely outside in a winter? Only the 3D simulation can answer a question like this. In this example, the condensate drainage channels were found to freeze, which would prevent water discharge, and lead to water damage.

Note to Specifiers: If you specify 3D analysis, please kindly consider getting a second opinion. We observed some architectural specifications ask for 3D simulations to verify either irrelevant or inferior performance requirements. Not that we mind very much, but in our reports we have a fiduciary duty to report any observed weaknesses to contractors who hired us to perform the work. Your client may be unhappy to find out, because these simulations tend to be expensive.

3-Dimensional Transient Thermal Analysis Performed to assess the passive solar design with materials of large heat storage capacity or to assess the condensation risk. Useful in analysis of 3D assemblies made of high-heat storage capacity materials, such as masonry and concrete precast. Would they store and release enough heat to ride through the cold winter night? Would they absorb enough heat to ride through the hot sunnmer day?We would give you the answer.

One-dimensional Transient Hygrothermal Analysis Would there be a water damage inside, at the absence of any rain intrusion or plumbing leaks? Microbial growth? We found the answer in many cases is yes.

These analysis are performed in design stages, in order to assess the moisture behavior of very simple assemblies. Most typically performed to assess the need and location of vapor retarding layers.

We also perform a long-term hygrothermal monitoring of assemblies in the field, in order to identify sources of moisture damage after the possibility of leakage has been ruled out.
