Twenty-two prefabricated modules—each weighing 18 tons—were hoisted into place on Lehman College's campus with a 600-ton crane.

The steel-and-concrete modules were built in an enclosed facility in Ephrata, Pa., which kept them largely immune to the weather and normal production delays associated with the traditional construction process. Lehman estimates that, as a result, the interval from groundbreaking to occupancy will be reduced by approximately half the time, providing a significant savings in time and construction costs.

Containing not only walls but also windows, flooring, lighting, plumbing fixtures and other major elements, the modules were 99 percent complete when they were trucked to the Bronx. All of the modules were lifted onto the site's concrete foundation in just three days (9/25-9/27).  The contractor will make final connections between modules and to utilities, finish site work, install final interior finishes and paint unfinished walls.

We're working on a large scale modular housing development in Williston, North Dakota.  Check back to see the progress!

NZ99: Net Zero for the 99%

The NZ99 home is designed to take full advantage of factory fabrication to produce a two module net zero house at an affordable price. This house is developed from our designs for high performance, high durability housing for the US Customs and Border Patrol and is the product of extraordinary research and development.  Its features include:

A complete cost of $304,000.  Includes site work, utilities, and energy generation systems and is based upon a northeast, 40 degree latitude, accessible, low slope site and New York State (NYSERDA) energy rebates.

-1500 square feet including three bedrooms, two baths, and a 24 x 24 living/dining room.
-Glazed southern exposure with R6 Heat Mirror Glazing and a continuous porch/overhang to control summer sun.
-18,700 kwh/year energy budget/generation from combination photovoltaic and solar thermal components.
-High performance double stud envelope with minimum R30
walls and R53 roof.
-Energy monitoring system, high efficiency reversible heat pump (heating and cooling) and heat recovery ventilation.
-Prevailing breeze/buoyant air ventilation penthouse over kitchen.
-Privacy screens or building integrated planting on southern exposure.

Modular Day Care Center in the Factory

The benefits of modular building can be exploited beyond the single family home. Currently being constructed in a factory in Pennsylvania, our modular Child Care Center for CUNY Lehman College in the Bronx demonstrates the advantages of industrialized building in a non-residential context. The modules are fabricated at the factory at the same time as foundations are being laid at the site. For a busy urban campus, minimizing disruption is key -- the building modules, once complete, will be transported and installed on site within a week.

Stay tuned for more updates on this exciting building process! In the meantime you can find out more about the project on our website.
