The Zeroth Law of Thermodynamics states that two objects in thermal equilibrium with a third system are also in thermal equilibrium with one another. This law is the basis of temperature – temperature flows from hot to cold; therefore, when systems are in thermal equilibrium, they are

If all existing commercial building windows were replaced with triple pane windows, it would save around 1% of the total energy usage in the US, according to 2012 estimates from the US Energy Information Administration (EIA). Put into perspective, that is roughly equivalent to how muc

“Energy efficiency offers a vast, low-cost energy resource for the US economy – but only if the nation can craft a comprehensive and innovative approach to unlock it…If executed at scale, a holistic approach would yield gross energy savings worth more than $1.2 trillion, well above th

Sound ratings were developed by the American Architectural Manufacturers Association (AAMA) and the American Society for Testing and Materials (ASTM) to standardize the testing and rating of sound transmission for building components, particularly windows. Two sound ratings are mainly

The Empire State Building has over 6,500 windows – and with windows being one of the main causes of poor building energy performance, the historic landmark NYC building had a lot of room for improvement. In 2009, the Empire State Building began work on a retrofit project that would mo
