With a short investigation, we add our contribution to what has been recently published by some Italian consumers and professionals associations. Although the example described in this article is purely Italian (and deeply so), we believe that the same situation with thermal paints is happening in other countries too. Here we try and evaluate how solid this products are, and whether or not they can be helpful, with an example of a thermal bridge.
During Enrico’s recent visit to Colorado, we finally had the chance to visit Andrew Michler’s passive house. At about 2.000 m (6.400 ft), in the mountains near Fort Collins, Colorado, this building is capable of remaining comfortable even in case of a power outage, with an interior temperature of about 18°C (64°F) with no heating.
With this article, we address one of the most important topics in the field of energy efficiency: the airtightness of the thermal envelope. Whether the building is a new construction or a renovation, its airtightness plays an important role for comfort, energy efficiency and durability of the structure.
We continue our series of articles on the topic of thermal bridges: this time, we illustrate the fRsi value, which describes the thermal ”strenght” of a node under the point of view of internal surface temperatures. As we have explained in a previous article, the PSI value describes a higher or lower heat flow caused by a discontinuity in the thermal envelope - a thermal bridge - the fRsi factor is of primary importance for health and comfort considerations.
Last week Enrico took part in the 2015 Passive House Window Talks in Nova Lehota, Slovakia, a two-day event on the benefits of high-performance Passivhaus windows. It was organized by ProPassivhausFenster, a group of small European window manufacturers well known for their award-winning Smartwin windows, but it was far from the usual company-sponsored workshops designed to sell product. Architects and engineers gathered together to discuss and learn more about the technical specifications and the fundamental need for high-quality windows in everyday design.
Over the years, the construction industry has been moving in the direction of energy efficiency and environmental sustainability. However in some cases, this change has happened only from a marketing point of view: with this article, we provide you with two interesting stories.
