Although mostly my engineering research, teaching and consulting concerned mechanical design, my PhD research was about heat transfer. At IIT a study I did many years ago for the Window Shade Manufacturers Association investigated the benefits of window shades in controlling heat loss/gain through windows. For that study another professor and I built a carefully insulated room with a typical window in one wall. Direct sunlight was simulated with a bank of Kodak projector bulbs. Measuring flow rate and temperature of airflow circulated showed the reduced heat gain when the shade was pulled down.

The Marvin Family of Brands offers a wide variety of crank-out and push-out casement windows available for replacement, remodeling or new construction.

There is some sort of thermodynamics principle about this. Stained glasses was also used by buildings and churches as their window. Aside from it is appealing to the eyes of people, it also involves heat absorption wherein it controls transfer of heat between two systems. Researches also found out that its advantage also includes energy conservation. However, stained glasses installation is expensive than we think.

Window shades help control the heat loss or gain through our window. A research states that black shades traps the heat inside while white reflects it. It might be a good idea to install white windows to redirect the direct sunlight but still provide natural light. Black windows not only traps the heat inside but also prevents natural light to enter. It is ecological and economical to install white windows.

Window shades help from direct sunlight entering into our rooms. These help in controlling of heat entering through windows. It is good to hear that you have done research on this shades and designed a window shades. These shades are very much important for windows.

We seem to be a culture that loves to fix the word "smart" into new technology advancements and there's no shortage of tech that is just that. While these tech advancements often sound more like science fiction, they're growing every popular and there's no shortage of these types of advancements for the home. The most prominent now is smart glass - which acts like a solar light switch for the home. Instead of relying in window treatments to block light this advanced replacement window automatically controls the level of light penetration into the home.

This is an amazing discussion going on here. Really sun is the best source of providing energy. But during summer, when it really gets hot, one need to cope with it. Shaded glass panels are not new in market, but effective one are just now finding their way. Amazing topic for research.

Engineering research is the main cause of the development today. The one of the main problem to focus is how to control the climate of inside the building with so much global warming, this research is going to open a whole new dimension of heat control and building architect. Amazing.

Growing flowers, plants and vegetables with LED lights is a balance of multiple variables including proper and correctly timed nutrition, precise watering, correct room temperature and proper LED lighting coverage design. If you are a veteran gardener this is already known. If you are new to this fascinating world of greenhouse or indoor gardening do not get overwhelmed.
