Results of Comparable Energy Efficiency in Manufactured Homes Revealed

May 3rd, 2016 Comments off

electric_meter_fotoseach_2_comThe Manufactured Housing Institute (MHI) tells MHPronews a three year project undertaken by the Department of Energy (DOE) compared the energy-saving attributes of three lab houses of varying designs tested side-by-side under controlled conditions in Russellville, Ala. The homes were built by Southern Energy Homes, part of the Clayton Homes family.

The first home, Home A, met the minimum standards of the HUD Code. Home B was an ENERGY STAR home. Home C was a high performance home , the nation’s first certified as a DOE Zero Energy Ready Home.

In terms of energy consumption, House C used half the energy of the other two houses for cooling. House B used slightly less energy than House A for cooling. There was virtually no difference in the amount of energy used for heating houses B and C, which amounted to almost one-third of the heating energy consumed by House A.

Because of the added exterior foam insulation, Home C had higher wood moisture content than House B, but still within safe limits. The insulation also resulted in a higher average temperature (5.5 degrees) during the heating season.

Peak demand was lower year-round in Home C than in either A or B. House A peaks were a little higher than those of House B in most months, although in the winter A and B were similar. On average, during peak hours House B had an 18 percent lower peak demand than House A, while House C’s peak demand was 69 percent lower than House A.

Counting only energy efficiency additions, the cost to the manufacturer to build House C compared to House A and B was $2,060 and $1,166, respectively. The price for the consumer to purchase C compared to A or B would be $6,607 and $4,339, respectively. The simple paybacks to the homebuyer associated with building House C compared to House A and House B ranged from approximately 8.8 to 17.5 yr. ##

Panoramic’s Kennedy says, best and worst of times

August 29th, 2013 Comments off

epoch-times-micro-apartment2-daily-business-news-manufactured-housing-pro-news-com-ani1-Panoramic Interests CEO Patrick Kennedy says that for San Francisco developers, this is the best and worst of times. Epoch tells MHProNews that for those building in currently under-supplied market, it’s a good time. But costs are high, which are ultimately passed onto consumers. So Panoramic used modular construction for an infill recently to do a micro-apartment built offsite by Pankow and designed by ZETA Design+Build. “We wanted to use this as an example of how to use hyper-dense, hyper-green, hyper-efficient urban development,” Kennedy said. “The micro-apartments by their very nature use far fewer materials to satisfy basic housing needs; they’re also super efficient in terms of energy consumption. I think our typical apartment’s electrical bill is less than 15 bucks a month,” Kennedy said. The next project will be 120 units. ##

High Income Residences for Low Income Residents

October 26th, 2012 Comments off

Philly reports low-income housing in a section of Philadelphia called Logan rivals high-income housing elsewhere. The three modular rowhouses are stylish and modern, and among the most energy efficient homes anywhere, with solar paneled roofs that reduce the energy consumption level to near zero, crucial for the poorest of the poor who will be living there. Developed by Onion Flats, the homes are the first in Pennsylvania to be certified by the Germany-based International Passive House Institute because their energy consumption is near zero. Stuffed with insulation and outfitted with Bosch appliances and European windows, a heat exchanger maintains a comfortable temperature inside the homes. Partnering with the nonprofit Raise of Hope, Onion Flats  set 25-foot deep piers to stabilize the modules because of Logan’s shifting soil. Costing $250,000 apiece, the five-bedroom homes will be occupied by families with incomes below $25,000 annually, MHProNews has been informed.

Modern Mod in Latin America

October 23rd, 2012 Comments off

SmartPlanet informs MHProNews from Buenos Aires, Argentina prefabricated housing has meant low cost housing for years in Latin America. Additionally, labor is very low cost, so stacking bricks to make a home is relatively inexpensive. Sebastian Koltan has developed a galvanized steel-framed modular house with distinctive sustainability features: polyurethane foam-filled walls, solar water heater, water cachement for greywater and low energy consumption LED lights. Customers can add modules in multiple configurations for a larger home, and increase energy efficiency features however they wish, with prices starting around $150 a square foot. The modular unit has generated a lot of interest in people wanting a second home in the country or at the beach.

New Roof System Saves Energy Expense

September 11th, 2012 Comments off

GizMag reports a new roof and attic system developed by the Dept. of Energy that can be retrofitted to existing homes could save homeowners $100 a year, offsetting the $100 to $300 typically lost annually because of poorly sealed heating and cooling ducts that leak conditioned air into attics. Developed at the Oak Ridge National Laboratory (ORNL), the passive ventilation system moves air from the underbelly of the attic that normally goes into the house, and carries it up and out. Featuring a foil-covered polystyrene insulation that fits over and between rafters in new construction, or attached to a shingled roof on existing homes, the system also has controls for radiation and convection. MHproNews has learned the $2000 for installation is far less expensive than spray foam in reducing the average household’s energy consumption.

NH Program Helps MH Residents Save Energy

May 15th, 2012 Comments off

The U.S. Dept. Of Energy has contributed $600,000 to Southern New Hampshire Services project to weatherize 100 homes in Exeter’s four MHC Co-ops. The Regional Greenhouse Gas Emissions Reduction Fund through the N.H. Public Utilities Commission is donating $2 million for the program to expand to 425 homes in 20 resident-owned communities across the state by the end of the year. SeaCoastonline tells MHProNews.com Rick Minard of the state’s Community Loan Fund says the cost to weatherize each home is $6,500 but it reduces energy consumption by about 25 percent. The energy auditors who do the work also check for gas and carbon monoxide leaks. The materials and service are free, but applicants must qualify for fuel assistance in order to be eligible for MH weatherization.
