  As Ms. Hardy says, there are two paths.

  Option 2, the "prescriptive path, or partial house option., is the more traditional, with, e.g., set Energy Star specs for new windows and doors, etc. etc.

  But Option 1, the "performance path," based on the whole house, is based on the aggregate energy savings (using HERS, pegged to square footage). This is more flexible, and therefore, as Ms. Hardy says, better suited to historic structures. E.g. if you have older windows that are not super-energy-efficient, you can make up for that through efficiencies elsewhere, as long as the total comes out right.

  Here is general information on the stretch code and changes going into effect July 1:

    There are two ways a renovation or an addition can meet the requirements of the Stretch energy code:

    <!--[if !supportLists]-->1.       <!--[endif]-->Buy rated products and install them according to directions.

    <!--[if !supportLists]-->2.       <!--[endif]-->Have an energy audit and produce a HERS score for the entire addition. 



    Obviously if the homeowner wants to restore they are not going with option one but can go with option two. Some inspectors are OK with it, others only seem to know about option 1 so there may be some educating. There are many energy auditors who can produce a HERS rating score.

    greetings all......

    i have had a call from a homeowner in belmont concerning windows and the stretch code...as i am not familiar with all the particulars, i turn to the informed folks on this list serve...



    the homeowner is converting a once unfinished (uninsulated, unheated) room in her house to a heated living space...the home is not on the registry and is not in an historic district...she would like to restore the existing window sash and install new storm windows...my understanding is that the stretch code is adopted by each town/city and the code may be slightly different from town to town depending on how the citizens/inspectors constructed the code...what should the homeowner know prior to applying for a permit for the conversion?  we all know that an old window with a new storm and weather stripping will offer the same U value as a new window but it can be an uphill battle convincing those who make the decisions...



    thanks in advance....
