Lighting selection

In a materials reference showroom, an area of study carrels is set aside for industry professionals to review product literature and reference materials. The showroom's reference center is open from 7 am through 10 pm every day and the owners of the center would like to reduce the energy consumption and expense. Which of the following is the best choice of lighting selection for this portion of the center. A. ambient lighting B. general illumination C. task lighting D. accent lighting

Calculating daylight

The daylight factor method (CIE - E.U.) calculates how much daylight reaches any location in a room assuming overcast/diffuse conditions; and can account for corner windows, which cannot be accounted for using the lumen method (IES - U.S.). When 2,200 fc is measured on the ground outside, what is the resulting illumination level if one end of a room has a daylight factor of 2?

Noise transmission

Which is true?  A. The level of airborne noise that passes through either a floor/ceiling or wall assembly at a specific location produces an IIC rating.  B. The level of airborne noise that passes through either a floor/ceiling or wall assembly at a specific location gives an STC rating.  C. Sound transmission occurring due to impact noise transferring through a floor-ceiling assembly gives an IIC rating.  D. Sound transmission occurring due to impact noise transferring through a floor-ceiling assembly produces an STC rating.

Need to learn more about Fenestration?

Both the Building Systems and Building Design & Construction Systems exams will address aspects of fenestration and the building enclosure. A resource to bookmark is the National Institute of Building Sciences NIBS and its many committees. BETEC: Building Enclosure Technology and Environment Council, in particular, offers some of the more informative symposia and conferences. Read about  research and innovations in high-performance facades from their January 2013 conference are-review.blogspot.com
