Passive House US, Dew Points in Wall Assemblies, Part 1 of 2

I have just finished my Phase 3 training, in Golden Co. This week. We are officially Passive House US consultants. We plan on being certified next month at thePassive House Conference in Portland, OE.

Today I am going to talk about the effects of Super Air Tight Buildings on wall assemblies / dew points in the Atlanta Climate. A typical wall assembly on a new construction homes in Atlanta, Georgia contains 2 x 4 studs filled with insulation. On the exterior we have OSB sheathing, covered by an air tight / moisture barrier (I use Typar), and a veneer, usually brick or a cementitious cladding. On the interior we have ½ gypsum board painted usually with 2 coats of paint / primer. . . . → Read More: Passive House US, Dew Points in Wall Assemblies, Part 1 of 2

Reflections from Passive House, USA Training Sessions, Part 1

What is Passive House? “The Passive House Design standard is a performance-based and verifiable building energy metric that has been established based on global carbon reduction needed to avert the climate crisis as well as future costs of fossil fuels (peak oil) and therefore the economic feasibility to society.” The Passive House Standard requires reducing the space conditioning energy load (of new buildings) by 90% when compared to existing buildings…

The goals of a Passive House are:

To keep the requirement for heating and cooling a home to less than 15 KWH/m2 per year. Keep specific primary energy demand to less than 120 KWH/m2 per year. Air tightness of less than .60 ACH at 50 Pascal. . . . → Read More: Reflections from Passive House, USA Training Sessions, Part 1

The South Gets its First Certified Passive House (Beats California to the Punch)

A rarity in the South. 204House, in Lafayette, Louisiana, was designed and built by architect Cory Saft to earn both Passivhaus and LEED Platinum certifications.

Although sustainable materials and energy efficient design have found their way into some post-Katrina residential rebuilds on the Gulf Coast, Louisiana isn’t otherwise known for leading the charge to greener home construction. And that puts the house built by architect Corey Saft at the forefront of green housing in the state. . . . → Read More: The South Gets its First Certified Passive House (Beats California to the Punch)
