Light Mirror

Architecture of sunlight


The concept is simple, inclined reflective panels at the edge of one roof redirect sunlight to another building. The sunlight becomes a controllable asset, and there are many benefits: free solar gains and natural light.

The system redirects daylight towards the openings of a building (windows and others) to increase the solar thermal gain and thus reduce the building's heating consumption. This reflective panel is installed on the roof's edge or in the upper part of a facade where the solar illumination has no daily calorific interest. It allows passive control of the sunlight's direction.

No motorization, no electricity, the product is a simple glass frame firmly attached to a facade. We can change the orientation angle of the frame with a bolt. It is designed to facilitate its installation and its durability.



We assist healthcare buildings in designing brighter and sunnier rooms while reducing their heating needs.

Feasibility study

Based on a model of the building and its environment, we prepare a pre-product specification, select proper technologies, and prepare a building roadmap. Get answers to the most pressing questions - how it looks, how it works, how much it costs.


Develop physical samples that showcase your product features.

We prepare a detailed product specification, select appropriate technologies, and prepare the study of thermal gain and quantify the new daylight factor.
You may use the first samples to present to your clients.

End-to-end product development

We develop the reflective panels to the installation-ready stage. We manage with you all partners and optimize the design to fit your facade, while you may focus on other aspects of your project.


In a nutshell

 LightMirror is a low-tech solar panel that does not produce electricity but reduces your energy consumption


GIS and big-data computation

A 3D city modelling study, with a simulation of the direct sunlight on facades, is used to help the authorities and the residents accept the project. The aim is to quantify direct sunlight and solar heat loss at each building in a city. Interpretations of the data are rich:

- cartography of the houses that do not receive solar heat through their windows and have energy precariousness

- reduction of neighbourhood conflicts due to a sunlight shadowing

- identification of areas where direct solar radiation is unnecessary and placement of the reflective panels to redirect the sunlight

- calculation of the energy saved by residents and their new daylight factor
