Kömmerling’s innovative and unique energy savings calculator enables consumers and specifiers to estimate he cost and carbon dioxide savings of installing certain types of window including 58mm, 70mm, and 88mm frames.
The cost efficiency of new windows is clear, in replacing draughty single-glazed windows and elderly first-generation PVC-u windows. The Energy Savings Calculator enables customers to check just how energy
efficient a company’s products are.
The Energy Savings Calculator takes into account the total window surface area, the type of windows being replaced, and the proposed new windows and estimates their ‘U’ value. The consumer then puts in the
choice of heating material used and the price per kilowatt. The results show the savings in the first year in terms of money and carbon dioxide reductions, which is then extrapolated over 20 years.
A typical house with 25 square metres of glazing with first-generation PVC-u double glazing which upgrades to a new 5 chambered Kömmerling C70 or O70 Gold system would save approximately £369 per annum with the resulting reduction of 1.328 tonnes of CO₂. Therefore when using the Energy Saving Calculator please select PVC-U, Building Depth 70 mm.
