Building America Residential System Research Results: Achieving 30% Whole House Energy Savings Level in Marine Climates; January 2006 - December 2006

The Building America program conducts the system research required to reduce risks associated with the design and construction of homes that use an average of 30% to 90% less total energy for all residential energy uses than the Building America Research Benchmark, including research on homes that will use zero net energy on annual basis. To measure the program's progress, annual research milestones have been established for five major climate regions in the United States. The system research activities required to reach each milestone take from 3 to 5 years to complete and include research in individual test houses, studies in pre-production prototypes, and research studies with lead builders that provide early examples that the specified energy savings level can be successfully achieved on a production basis. This report summarizes research results for the 30% energy savings level and demonstrates that lead builders can successfully provide 30% homes in the Marine Climate Region on a cost neutral basis

OPTIMALITY OF PRE-EMPTING REGULATIONS ON NATURAL RESOURCE USE

Firms are often confronted with regulations on their productive and commercial activities. In many instances a firm can take various actions to pre-empt regulations. This article determines the optimality of pre-emptive action for a firm subject to natural resource regulation. The regulation may be either fixed or relative to the production history. Dependent on the type of regulation, a firm can pre-empt by terminating its current use of resources and converting to other use or by building up the input use or output history in the period prior to regulation. It is shown that the optimal pre-emption decision depends on the extent and perceived probability of regulation, on the rate of discount and on technological characteristics of the production process including the alternative use of the resource.
