Smart window films for heat and light management in buildings

Solar heat through glazing causes overheating of buildings. Therefore, there is an increasing energy demand for artificial cooling of indoor spaces. In this work we develop smart window films that autonomously control solar heat and daylight transmission through glazing based on changes in outdoor weather conditions. Besides color-neutral, also films with special reflective colors can be prepared. The films can be adhered to existing glazing and thus provide a cost-effective renovation solution.

A new standard test procedure for ARC abrasion resistance assessment of solar glass coatings on original format panels

For a standardized assessment of the abrasion resistance of anti-reflection coatings (ARC) in solar energy applications like photovoltaics, solar thermal modules, architectural and green house glasses, a full area cleaning test setup and test method was developed (DIN SPEC 4867).
The test procedure that simulates realistic cleaning loads by means of dust application and rotating brush cleaning is presented. The resistance of ARCs as well as damage potential of brushes can be assessed.

Glass in the built environment: the six most important trends according to expert interviews, systematic text processing, and cluster-based data analysis

The six identified trends deal with the integration of circular glass strategies, the future development of large-scale glass panes, the motto 'glass = wellbeing', multifunctionality & adaptivity of glass, the implementation of functions & technologies via dynamic glazing systems, and the use of thin glass. In addition, five so-called 'drivers of progression' can be determined: performance, aesthetics, environmental & sustainable aspects, financial considerations, and the human factor.

Using Nanoparticle Approach to Implement Smart Glass and Windows as Displays

Nodis founders Mike Holt, CEO, and Dr. Sergey Shokhor, CTO -- will discuss the technology and approach in implementing TruTint, the applications and market opportunities, and Nodis' plans in scaling it in mass production. Nodis TruTint is the world’s first smart glass technology with instantly electrically switchable color, infrared filtering and tinting (TruTint), reducing building energy consumption by 50% and extending Electric Vehicle range. This presentation will discuss how this works.

Face to face: the potential of a novel façade control based on facial expressions

In this paper, a novel dynamic liquid crystal switchable glazing technology is controlled by a human-centred system based on occupant’s facial expression (facial action units, FAU) and a wearable lux sensor to sense visual discomfort in real-time and in a non-disruptive manner. Experimental data on occupant satisfaction and discomfort is collected to compare the performance of a conventional benchmark control system with the novel occupant-centred system proposed in this work.

Thermochromic Smart Windows - Optimized Solar Heat Management via Autonomous Adaptive Glazing

Thermochromic smart windows can autonomously adapt their interaction with sunlight upon temperature as external stimulus. This enables use of solar heat to heat up buildings and create a comfortable indoor climate in winter, whilst blocking solar heat from entering the building in summer, reducing air conditioning demand and increasing comfort levels. We report the first system with change in g value of 11% approaching market introduction and analyze potential impact on the EU building stock.

Significant CO2 emission reduction in glass melting by advanced tank designs

The ETS phase 4 finally gives challenging CO2 emission limits for container and float glass production. Cost of energy carrier, availability, carbon footprint and technology readiness are key criteria for a technology decision. The talk goes back to the basics of the energy input by different carriers into the melting process and its consequences for the tank design. Design examples for container and float tanks will be given that focus on high electrical boosting input (hybrid designs).  Hydrogen combustion, oxygen combustion and full electrical melting will be screened.

Development of Optimal Structures of Cover Glass for Improved Efficiency in Solar Modules

Structures in glass improve light coupling into the module and internal light management through enhanced internal reflection. We study the influence of structured backside glass for bifacial modules on module power output and theoretical structure adapted to realistic production conditions by implementing roundings. These results are compared to modules with conventional white polymer backsheet. We show, structured glass can replace backsheets without greatly affecting internal reflection gain.

Mechanical strength testing and evaluation of thin large-format solar glasses

Larger wafer formats are being introduced in the solar industry, resulting in larger module dimensions of up to 2.3 x 1.3 m². Glass strength under high loads (storm, snow load) is an important quality assurance issue. In this paper, a test setup for strength testing of large-sized 2 mm panes is presented. Due to the geometric nonlinearity, the evaluation must be supported by a finite element simulation to determine the fracture stresses.

Design and durability of cold-bent insulated glass units

Curved and free-form façades including the use of insulating glass units (IGUs) represent a clear trend in architectural design. Hot bending is the most common technique used to produce curved IGUs. Although its effectiveness has been proved in many projects, it is well known that it can be very expensive due to the big amount of moulds usually required to build up a free-form façade.As alternative to the ‘hot-bending’ technique, the increasingly used ‘cold-bending’ method is investigated in this paper being less expensive as well as more sustainable. Such method consists in imposing an out-of-plane displacement to flat insulating glass units and generally requires forces of limited magnitude applied on site during installation.Cold-bending introduces permanent loads into the glass panes, the glass interlayers, the secondary sealing as well as the primary sealing, the latter one responsible for the gas retention and the resistance to moisture penetration in the IGU cavity. Focusing on both integrity and durability performance, the paper presents the results of FEM analysis as well as tests performed on double glazed units including Sikasil® IG-25 secondary sealing joints and SikaGlaze® IG-5 PIB as primary seal and investigates their behavior due to cold-bending and exposure to climate conditions in accordance with EN1279-2. The limit identified is applied for the design of cold-bent IGUs in a high-rise building facade.

Facing up to global challenges through the application of microstructures in glazing

The global building industry is changing due to enhanced building directives and an increased focus on CO2 emissions and indoor climate. For years, the innovation has been aimed towards controlling the amount of energy from the sun that enters a building. However, as these requirements often exceed what conventional glass coating solutions can deliver, the industry has had to adopt to expensive external shading systems and double facades. The challenge with conventional shading systems is, that while they are effective in providing solar shading, they also reduce the daylight intake and the view to the outside. In addition, the conventional shading systems are expensive, complex to install and operate and have limited lifetime expectancy. Therefore, new approaches need to be invented. Solutions that provide effective shading, while maintaining the natural daylight and the view to the outside. At MicroShade we have found that all of these needs can be addressed through the application of microstructures inside the glazing.
