Revolutionary Comfort: IQ Radiant Heating Glass

IQ Radiant Heating Glass (IQRG) transforms modern living with its innovative electrically heated glass technology. Designed to address common construction challenges, IQRG offers unparalleled energy efficiency, thermal comfort, and condensation control. Each piece of glass functions as a local heating zone, seamlessly integrated with an AI-driven building management system that adapts to outside temperatures and occupancy patterns. Perfect for a range of applications from residential homes to commercial spaces, IQRG ensures a comfortable and efficient indoor environment, revolutionizing the way we experience warmth and comfort in cold climates.


Introduction

IQ Radiant Heating Glass (IQRG) is an electrically heated glass providing a unique problem-solving solution to several construction difficulties. The concept of electrically heated glass is based on the electric characteristics of Low-E glass, first utilized in Europe in 1986. This innovation has been installed in office buildings, restaurants, hotels, corporate headquarters, public swimming pools, private homes, conservatories, and winter gardens.

IQRG can be used in all standard window structures, whether they are in wood, PVC, aluminum, or steel. It eliminates all the difficulties and disadvantages caused by the thermal insulation capacities of glass. The heating glass surface eliminates the sensation of cold draft, prevents surface condensation, compensates for the loss of temperature through the glass surfaces, and melts snow and ice on the outside of the window when set up for that purpose. Creating comfort is one of the main advantages of heating glass.


IQRG is primarily used as a sole heating source but can easily be combined with existing heating systems that are incorporated into the building structure, such as floor heating, ceiling heating, and heating panels. IQRG increases living comfort by eliminating the sensation of cold draft. This effect is reached by raising the surface temperature of the glass to the same level as the air temperature of the surrounding objects. IQRG eliminates the necessity of radiators near the windows, therefore achieving dramatically more living space. One of the typical characteristics of heating glass is that it allows you to lower the room temperature by several degrees (3 ºC or 9 ºF) without any impact on the comfort of the living surroundings. This phenomenon means important energy savings compared with traditional glass and heating systems.

IQRG Radiant Heating Glass (IQRG) offers a solution to this problem. Heating glass allows you to raise the glass surface temperature to a level where the disadvantages of cold radiation disappear.



Light Transmission and Energy Transportation

When the inside temperature of a house is higher than the outside temperature, heat will filter to the outside. The windows are part of the building with the lowest insulation capacity. The temperature losses through the windows are usually substantial.

In a traditional detached house, glass surfaces are responsible for about 20% to 25% of total heat losses. Increasing the number of glass layers may improve the thermal insulation capacity, but every additional glass plate reduces light transmission and increases the price.

IQRG is based on low-e glass. The light transmission factor is the same as for normal glass, but the IQRG glass configuration reflects the thermal radiation back to the inside of the building and offers protection against extreme heat gain during the summer.

Low emission glass reduces temperature losses via thermal radiation. The convection and heat induction in the space between the glass panes of an insulating entity can be reduced by filling the space with a low conduction capacity gas such as Argon (Ar) or Krypton (Kr). IQ Glass, Inc. uses Krypton, which further reduces heat losses by about 10% to 30%.


Radiant Heat


Heat losses through materials such as glass are characterized by a U-value (insulation value).


Glass Structure U-Value (W/m²K) U-Value (Btu/hr ft² ℉)

Single Glass 5.8 1.021

Insulated Glass Unit (IGU) 3.0 0.528

IGU with Triple Glass (gas-filled) 1.8 0.317

IGU with Low-E Glass 1.3 0.229

IQRG Insulated Glass Unit (*) 0.84 0.148


(*) The center pane U-Value of IQRG is 0.162 Btu/hr ft² ℉ (0.92 W/m²K). Including the edge effect of the super-spacer reduces the U-Value of the complete IQRG IGU to an average value of 0.148 Btu/hr ft² ℉ (0.84 W/m²K).


Comfort and Causes of Discomfort


Thermal comfort depends mainly on a combination of the air temperature and the average radiant temperature. The term ‘comfort zone’ refers to these combinations of air temperature and average radiant temperature that make one feel comfortable. IQRG ensures via a combined system of thermostats, glass surface temperature sensors, and microprocessors that this will always be achieved. The control system is explained in the section “Control and Regulation of IQRG”.


Applications of IQRG


IQRG can be used in a variety of applications including homes, conservatories, restaurants, and more. It can come in all shapes, including bent glass, and sizes up to 8000 x 3200 mm. It is also UL certified. This makes it versatile and suitable for many different building designs and requirements.

IQRG can be integrated with an AI machine learning building management system. This system adjusts to the outside temperatures in cold months and learns when the lodge will be occupied and which rooms will be occupied. This ensures efficient heating only where and when it is needed, further enhancing energy savings and comfort.


In summary, IQ Radiant Heating Glass is a groundbreaking innovation in building technology, offering unparalleled benefits in terms of energy efficiency, thermal comfort, and versatility.
