The database application also tracks the outcomes associated with many of these program activities, including environmental, behavioral, and economic outcomes. Because each state's pollution prevention and compliance assistance program is somewhat different in the scope of its activities and its structure, the software can be customized so the programs can use only those components and the level of detail that suit their needs.
Re-nourishThe Re-nourish Project Calculator helps you minimize waste on any print project, reducing your environmental impact and saving your client money by using less paper.
Roof Savings Calculator (RSC)The Roof Savings Calculator was developed as an industry-consensus roof savings calculator for commercial and residential buildings using whole-building energy simulations. It is built upon the DOE-2.1E engine for fast energy simulation and integrates AtticSim for advanced modeling of modern attic and cool roofing technologies. An annual simulation of hour-by-hour performance is calculated for the building properties provided based on weather data for the selected location. Annual energy savings reported are based upon heating and cooling loads and thus this calculator is only relevant to buildings with a heating and/or cooling unit.
Steam CalculatorsThere is often flexibility in the operational conditions and requirements of any steam system. In order to optimize performance, the impacts of potential adjustments need to be understood individually and collectively. The Properties and Equipment Calculators allow you to input the metrics of your system, generate a list of detailed system specific steam properties, and test a variety of adjustments on individual equipment. The accompanying Steam System Modeler allows you to create up to a 3-pressure-header basic model of your current steam system. A second model can then be created by adjusting a series of characteristics simulating technical or input changes. This allows you to see how each component and adjustment impacts the others and what changes may be most beneficial to increasing the overall efficiency and stability of the system. An interactive diagram is provided for each model and includes comprehensive steam properties and operational details for clarity and ease of use.

SNAP List of SubstitutesSubstitutes are reviewed on the basis of ozone depletion potential, global warming potential, toxicity, flammability, and exposure potential as described in the final SNAP rule (59 FR 13044; 967K). Lists of acceptable and unacceptable substitutes are updated several times each year. A chronological list of SNAP updates is available.
The SNAP program makes decisions on a particular substitute in a particular end-use within a larger sector. For example, within the refrigeration and air conditioning sector, HFC-134a is acceptable as a substitute for CFC-12 in new and retrofitted household refrigerators. Acceptable substitutes are listed by end-use. These lists include substitutes that are either acceptable, acceptable subject to narrowed use limits, or acceptable subject to use conditions. Because the number of unacceptable substitutes is very small, they are listed by sector.
