Energy-Efficient Manufactured Housing:Energy Efficient Manufactured Housing(ST4939-1)

Steven Winter Associates, Inc.


Manufactured housing offers an excellent opportunity to incorporate integrated design principles, because a single entity is better able to take advantage of the efficiency gains from one subsystem to improve the designs of other subsystems. In 1996, the U.S. Department of Housing and Urban Development (HUD) contracted with Steven Winter Associates (SWA) to develop a series of advanced manufactured housing designs compatible with urban neighborhoods. In 1998, HUD contracted with SWA to build and demonstrate a two-story double-wide prototype design and a single-wide prototype home with structural insulated panels. SWA teamed with Titan Homes of Sangerfield, NY, to build the prototypes and erect them in New York State.

Project Description

SWA will: (1) conduct short-term performance monitoring and computer analyses on the prototype home and a conventional home to compare the energy expenses of each; (2) estimate the net economic benefit to the prototype home's owner; (3) prepare promotional materials that describe the benefits of the prototype home; (4) conduct presentations for the officials of 12-15 New York State cities that could benefit from the use of prototype homes in infill areas; and (5) monitor the prototype homes' potential acceptance in these cities.


The prototype home is expected to exceed the requirements of the Model Energy Code by more than 30% due to its use of increased insulation levels, high-performance windows, high-efficiency HVAC equipment, and other improved building systems. Titan Homes' current sales could substantially increase and, if the new home achieves expected market projection, create new manufacturing jobs in New York State.

Project Results

The heating energy required for the NextGen prototype was determined to be 23% lower than Titan Homes' standard model home of similar construction. This improvement was achieved by installing Energy Star windows and increasing the insulation levels in the walls, floors, and ceiling. The energy payback for these improvements would be 3.5 years, based on a liquid propane price of $2 per gallon. Titan offered a home model based on the NextGen home design. SWA presented the results of this project at workshops held in Albany, Buffalo, and Syracuse.
