Proposed tariffs by the incoming Trump administration may increase the prices of many items at the store. But for architects and advocates working on more efficient and sustainable buildings, theres fear that tariffs could impact specific materials and machines that are key to their work. Higher costs from tariffs, some say, may slow down the pick up of these techniques of residential and commercial construction, and make such buildings more expensive and less attractive to build.Firms could be hard put to keep pace with the cost of procuring materials like mass timber and products such as heat pumps after the proposed blanket tariffs are enacted, explains FastCompany. This would add stress and uncertainty to the already lagging American building industry, which is considered behind Europe as far as efforts to increase efficiency standards are concerned. Domestic manufacturing would have to rise to the challenge or risk falling back into the wrong kind of "American Exceptionalism" that is both environmentally unproductive and at odds with a global consensus on building sustainability.
