Why Energy-Efficient Solutions Are Essential for US Buildings
Buildings in the US account for a significant portion of energy consumption and carbon emissions, which makes it increasingly important for architects and builders to consider energy-efficient solutions in their designs. A critical, yet often overlooked, factor in building energy efficiency is managing temperature control in cladded façades. Jonathan Shaw, Managing Director of Armatherm™, a leader in thermal break technologies, explains the importance of thermal breaks in cladding and modern construction. He also highlights how investing in thermal bridging solutions can lead to significant energy savings and reduced operational costs.
The Vital Role of Cladding in Commercial Construction
Cladding is an essential component in protecting commercial buildings from external weather conditions and providing structural support. However, when the steel cladding framework bridges the insulation barrier, it can conduct heat out of the building, leading to increased energy loss. Installing a non-metallic thermal break in the cladding structure helps eliminate this heat transfer, while also preventing condensation and stabilising temperature fluctuations within the building envelope.
Condensation and Its Impact on Building Health
In buildings that lack an effective thermal break, cold outdoor temperatures can transfer inside, causing cooler spots on interior walls. These areas are more likely to experience condensation, which can lead to moisture build-up, damp, and mould—issues that can contribute to health problems such as respiratory conditions, including asthma. A notable example of this can be seen in the 1980s, when many US buildings faced similar insulation challenges, leading to costly repairs or even demolitions. Installing a thermal break could have prevented these problems altogether.
Balancing Thermal Insulation and Load-Bearing Capacity
Previously, when both high thermal insulation and load-bearing capacity were required, builders had to choose between the two. Armatherm™ has developed thermal break solutions that meet both requirements without compromise. In the past, Iroko timber was used in base column isolation due to its load-bearing capacity and insulation properties. However, over time, timber absorbs moisture, reducing its insulating properties and increasing the risk of rot. In contrast, Armatherm™’s closed-cell structure ensures that water is not absorbed, maintaining consistent performance throughout the life of the building.
Thermal Breaks: Saving Energy and Reducing Costs
Buildings that lack effective thermal breaks experience significant energy inefficiencies. Heat loss through poorly insulated structures increases the energy demand of the entire building, resulting in higher operational costs. Installing a thermal break can reduce energy loss by as much as 80%, leading to substantial savings on heating and cooling bills for commercial buildings.
The Importance of Modern Thermal Break Technologies
As US architects and developers strive to create energy-efficient, sustainable buildings, understanding the latest technologies is essential. A simple, yet powerful, solution like a thermal break can provide significant long-term savings on energy costs. By incorporating thermal break solutions into their designs, architects can ensure better energy efficiency and lower operational costs, helping their clients save money while contributing to a greener future.
