Finnglass windows improve thermal condition and carbon emission management<\/h1>\n

The Finnish glazing solution expert Finnglass wants to develop the responsibility of its production, which requires an assessment of its products\u2019 impact on thermal conditions and carbon footprints of buildings. This information was gathered by using Sweco\u2019s energy, carbon footprint and CFD calculation.<\/p>\n

Finnglass is a Finnish expert on electrically heated glass with nearly 40 years of experience in active glazing solutions. The company\u2019s greatest value is improving people\u2019s well-being. \u201cUnderstanding our customers is important to us, because today\u2019s offices, for example, are about working conditions, not just square metres,\u201d says Finnglass\u2019s CEO Timo Saukko. Thermal conditions have a significant impact on the satisfaction of those using the premises. \u201cAccording to studies, the most common complaints users have concern the space being too hot or cold.\u201d<\/p>\n

A responsible supplier impacts the customer\u00b4s carbon footprint<\/h4>\n

Responsibility permeates all operations at Finnglass, and all production processes related to roughing and smoothing glass are already carbon neutral. \u201cWe only use green electricity produced with renewable energy and the waste heat from our own processes,\u201d Saukko says. Indeed, Finnglass also wanted to determine the impact of electrically heated glass on the thermal conditions and carbon footprint of buildings. \u201cWe want to present our customers with proven solutions.\u201d<\/p>\n

Sweco\u2019s independent experts are investigating the energy consumption and carbon footprint of electrically heated glass in three different cases. \u201cWe combined Finnglass panes with underfloor heating, fan coil units embedded in the floor and coil units installed on floor surfaces,\u201d says Sweco\u2019s energy and carbon footprint calulcation expert Kari N\u00f6jd. This was followed by a comparison of the impact of underfloor heating and electrically heated glass on the thermal distribution and thermal comfort of the space.<\/p>\n

CFD calculations simulate indoor climate conditions reliably<\/h4>\n

The research methods included energy and condition simulations, carbon footprint calculations and demanding CFD calculations. \u201cCFD calculation requires supercomputers and special expertise, because the reliability of the calculations is fully dependent on the expert\u2019s skills,\u201d Timo Saukko emphasises. \u201cSweco has a high level of CFD and carbon footprint calculation competence.\u201d<\/p>\n

According to Sweco\u2019s Leading CFD Specialist Eero Kokkonen, ensuring thermal conditions and thermal comfort in the design of even slightly more complex spaces is extremely challenging without CFD calculations. \u201cIn addition to temperature, air flow speed and turbulence also affect thermal comfort,\u201d he says. The feeling of draught, for example, is a sum of many factors, such as geometry, window placement and the terminals of the ventilation system and their locations.<\/p>\n

The indoor climate is often designed based on averages. The average temperature of the entire space can, however, be a poor representation of the thermal conditions near tall windows, for example. \u201cThe design should not settle for being good on average. The conditions should be good throughout the space,\u201d Kokkonen stresses.<\/p>\n

According to calculations, underfloor heating alone cannot ensure the thermal comfort of spaces on cold days. The size, number and surface temperature of windows have a significant impact. \u201cIf the surface temperature of a window pane is lowered to one degree below room temperature, an unpleasant draught can be felt near the window,\u201d Kokkonen says. Electrically heated panes improve the user experience and functionality of the space. In addition to this, there is no need to install heaters or coil units in front of glass facades, which takes away from the architecture. \u201cIt also improves the efficient use of the space.\u201d<\/p>\n

Opportunity to optimise the carbon footprint<\/h4>\n

Based on a report, electrically heated panes can be used to meet the E value requirements set for new construction. The panes can also be used to optimise heating costs and carbon emissions.<\/p>\n

\u201cThe operation of electrically heated panes is easy to control, enabling them to only be heated when there are people in the hotel room or scenic restaurant, for example,\u201d N\u00f6jd says. \u201cWhen electrically heated windows are used when needed alongside a geothermal heat system, for example, they can be used to achieve a smaller carbon footprint than district heating alone.\u201d<\/p>\n

Finally, Sweco experts draft planning instructions that help architects, HVAC designers and electrical engineers take the characteristics of the electrically heated panes into consideration. \u201cEach designer wants to design buildings that meet high indoor climate and low-carbon requirements. We believe that it is important to provide them with the right information,\u201d Saukko says.<\/p>\n
