f ' CONSUMER INFORMATION FORM - "SUNROOMS"
Massachusetts State Building Code (780 CMR 6101.3.2.2)
The Massachusetts State Building Code (780 CMR) includes provisions to ensure that houses and
house additions meet energy efficiency standards. This supplemental CONSUMER INFORMATION FORM
is to be filed as part of the building permit application when a builder /contractor or homeowner,
constructing/installing a house addition with very large percentage of glass to opaque wall, seeks to utilize a
special energy conservation exemption option for " sunroom" additions to an existing house (780 CMR,
6101.3.2.2). This FORM is not intended to prevent a homeowner from selecting a "sunroom" of any size,
configuration, orientation, form of construction or percent glazing, but rather is only intended to assist
homeowners in becoming aware of some of the important energy conservation and year-round comfort
considerations involved in selecting and utilizing a "sunroom" addition.
•
The connection of "sunroom" structures to residential buildings may create comfort and energy consumption
issues due to uncontrolled solar gain or uncontrolled radiation cooling of the main house. In the selection and
construction/installation of "sunrooms ", included below is a non - required, open -ended list of product and design
considerations that a homeowner may wish to consider before actually constructing/installing a "sunroom ". It
is recommended that consumers carefully review these options with their designer, builder, or contractor, in
order to minimize potential energy consumption and/or house discomfort issues. In addition, the qualifications
and reputation of the company or individuals to be hired are important considerations.
