Large Building Airtightness Testing and the Selection of Appropriate Air Barrier Strategies

An airtight building enclosure is an important part of a modern building. Good airtightness can increase energy efficiency, improve durability, and allow greater control over occupant comfort and indoor air quality. Airtightness is achieved with an effective air barrier system that is carefully designed and detailed and then built and commissioned in the field. An […]

Energy Efficiency in Modern Buildings

As modern building materials advance, energy efficiency is inescapable. Near-zero energy buildings are becoming increasingly popular in Europe. However, this will not have a great effect on energy consumption as a whole until energy efficient building materials and practices are widespread. Iowa State University Professor Yu Wang states that energy efficiency is relatively inexpensive when […]

Creative Building Design Requires High Performance Water-Resistive Barrier Solutions

The Science Pyramid at Denver Botanic Gardens invites visitors to explore the relationship between people and plants, and to examine the role of biomimicry in our lives – the way the features of nature inspire ideas and actions in people. It’s not surprising then that the building has a great relationship with its surroundings. Rising to a comfortable height among the […]

Ashrae 90.1 Standard for Building Envelopes

First appearing in 1975, an updated Ashrae 90.1 energy standard for all but low-rise residential buildings comes out every 3 years. Taking into account current technology and life cycle cost, Ashrae 90.1 establishes minimum energy efficiency requirements for building design and operation including building envelopes (as of 2007). Ashrae 90.1 Currently, the Ashrae 90.1 uses the 8 […]
