More New Resources
By Tad Everhart

New England Forges Ahead, Low Carbon Productions’ sixth free book featuring 50 Passive House buildings from Maine to New York and from multifamily to mixed use is now available as a free flipbook or pdf.  New England Passive House designers and builders are among the most prolific in the United States with over 100 single family Passive House residences, several large Passive House multifamily buildings, and many special use Passive House buildings such as dormitories, cohousing communities, artist colony retreats, fieldhouses, and net zero energy office buildings.

The Passive House Institute has published this free 123-page flipbook covering virtually every aspect of phased (step-by-step) EnerPHit (Passive House deep energy retrofits).

 The guide includes a chapter on building envelope connection details, a chapter on equipment, and an example case study building.


Many people have found this Passive House “Details Book” by IBO, the Austrian ecological building research institute, to be a useful compendium of Passive House details, especially for evaluating connections where thermal bridges are hard to avoid.  Details also closely examines and evaluates the environmental aspects of all common building materials.

IBO recently published as second compendium of Passive House details.  This book is devoted to details for retrofitting buildings and is arranged chronologically with details for buildings created before the 19th Century through buildings from the 1970s and 1980s. 


This Details book is even more useful as it contains more details than the first Details book.  Also, it omits the German text.

Again, just as Details One includes extensive information on the ecological characteristics of all common building materials, Details Two includes 50 pages reporting on environmental aspects of all building insulation products.  And then conducts an environmental optimization to help you select the environmentally optimal insulation to add to each particular part of the building assembly.

Although Details Two is an investment of $60, it is a great value with 280 pages of explanatory text, illustrations, and calculated psi-values.  Judging by the first Details, it may be wise to buy the second book today.  Years ago, the first volume cost $80, but you can’t get it new or used today for less than $100 from online bookstore.  I found the best price for the new Details at Alibris bookseller with a coupon for free shipping.
