Building Energy Use Drops More Quickly Than Expected
Posted by Tasha Weiss on January 26, 2012 at 5:44 PM The U.S. Energy Administration (EIA) released the Early Release Overview of its Annual Energy Outlook 2012 on January 23, projecting that residential and commercial building energy use is expected to decline more rapidly in the next couple of decades than originally thought. EIA’s Annual Energy Outlook (AEO) projections since 2005 illustrate that estimates for energy consumption to 2030 have dropped by nearly 70% due to considerable movement within the building sector to improve building design and efficiency.
The final Annual Energy Outlook 2012 will be issued later this spring.
A movement that is making strides to reduce building energy consumption in the building sector is the 2030 Challenge. Developed by Architecture 2030, a non-profit organization dedicated to slowing and reversing the growth rate of greenhouse related emissions in the building sector, the program encourages the global architecture and building community to adopt various building energy reduction targets to achieve industry-wide zero net energy use by 2030.

What's being answered right now:
Q.
I am trying to design an unstiffened seated connection using Table 10-6 in the 13th edition manual. What is the definition of the required bearing length Nreq (in.) shown in the Table? Is this referring to the actual beam bearing length on the angle, and if so, why do the allowable load values decrease as the bearing length increases?
A.
The Nreq listed in Table 10-6 is the required bearing length to satisfy the Specification limit states; rather than the actual bearing length on the angle. Thus if the required bearing length increases, so will the eccentricity of the reaction on the seat angle, resulting in a lower strength. |
