Marc Rosenbaum Offers a Free Online Lecture
On September 4, Rosenbaum will give a free presentation on calculating heat loss to the ground
Heat loss from basements and slabs to the ground is complicated. If you're interested in learning more on the topic, you might want to take advantage of a free lecture being offered by energy expert Marc Rosenbaum.
At 1:00 p.m. on Thursday September 4, 2014, Rosenbaum will offer a free online lecture on heat loss to the ground. The presentation is intended for architects, builders, and others who want to have a better idea about how buildings interact thermally with the ground and how to calculate heat loss to the ground.
THERM and the Los Alamos algorithms
Starting with with the 2D THERM model of a basement, Rosenbaum will look at the U-factorMeasure of the heat conducted through a given product or material—the number of British thermal units (Btus) of heat that move through a square foot of the material in one hour for every 1 degree Fahrenheit difference in temperature across the material (Btu/ft2°F hr). U-factor is the inverse of R-value. that THERM calculates for the foundation assembly, and use that to calculate the design heat loss of the basement, and estimate the annual heat loss as well.
He will then do a quick reality check to vet that calculation, and present the simplified Los Alamos algorithms for calculating heat loss from basements and slab-on-grade foundations. These algorithms will be applied and compared with the THERM calculation.
Rosenbaum will also discuss how to apply these algorithms to a walk-out basement condition. Finally, he'll look at how to estimate design heat loss in the case where the insulation is in the frame floor over a basement.

Once again, Rosenbaum will offer a course on net-zero homes
Rosenbaum's free lecture is a teaser to lure prospective students to his online course, Zero Net Energy Homes, scheduled to begin on September 15. The Zero Net Energy Homes course is part of NESEANorth East Sustainable Energy Association. A regional membership organization promoting sustainable energy solutions. NESEA is committed to advancing three core elements: sustainable solutions, proven results and cutting-edge development in the field. States included in this region stretch from Maine to Maryland. www.nesea.org's Building Energy Master Series.
The tuition for that 10-week online course is $895. Enrolling in the course includes a membership in NESEA and discounted admission to the Building Energy conference in Boston. For more information, click here: Zero Net Energy Homes.
Marc Rosenbaum is a well-known energy consultant and the director of engineering at South Mountain Company on the island of Martha's Vineyard in Massachusetts. He is the author of many Green Building Advisor articles, including Minisplit Heat Pumps and Zero-Net-Energy Homes and Practical Design Advice for Zero-Net-Energy Homes.
