GBAGreenBuildingAdvisor.com has made arrangements to provide live video streaming of an educational seminar by two renowned building science experts, Joseph Lstiburek and John Straube. Dubbed the Building Science Experts' Session, the seminar is being held on Wednesday December 5 and Thursday December 6, 2012, in Westford, Massachusetts. Sessions begin each morning at 8:00 a.m. Eastern Standard Time.
The video stream will be available at no charge to all GBA Pro members. A link to the live video stream will be added to this page on the morning of December 5, 2012.
Wednesday December 5 is "Spray Foam Day" with Joseph Lstiburek. Dr. Lstiburek will present a full-day session on spray foam issues and solutions using information based on field experience and laboratory research. Throughout the day, Joe will call in other industry experts for special cameo appearances and invite other BSC researchers to report on recent work.
Thursday December 6 will feature John Straube, who will cover "HVAC(Heating, ventilation, and air conditioning). Collectively, the mechanical systems that heat, ventilate, and cool a building. for Low-Load Buildings." Dr. Straube will define low-load and ultra-low-load buildings, and will discuss the enclosures that are needed to get there. Next, the implications of these low load enclosures on heating, ventilation, hot water, and other building systems will be explored. Fossil-fueled, electric, solar and biomassOrganic waste that can be converted to usable forms of energy such as heat or electricity, or crops grown specifically for that purpose. will all be addressed. This session is intended for designers and builders of ultra efficient residential (i.e., Passive HouseA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates., DOEUnited States Department of Energy.
