  2. Cooling load temperature difference calculation method

    en.wikipedia.org/wiki/Cooling_load_temperature...

    The respective tables of data were generally developed by using the more complex transfer function method to determine the various cooling loads for different types of heating. [ 2 ] [ 3 ] The results gained by doing so are then normalized for each type of heat gain used for the tables, CLTD, CLF, and SCL.

  3. Sensitivity analysis of an EnergyPlus model - Wikipedia

    For example, the BCVTB can simulate a building in EnergyPlus and the HVAC and control system in Modelica, exchanging data between them as they simulate. Programs that can be linked to BCVTB include EnergyPlus , Modelica ( OpenModelica or Dymola), Functional Mock-up Units , MATLAB , and Simulink , Ray tracing (physics)|ray-tracing , ESP-r ...

  4. International performance measurement and verification protocol

    en.wikipedia.org/wiki/International_performance...

    The purpose of the IPMVP is to increase certainty, reliability, and level of savings; reduce transaction costs by providing an international, industry consensus approach and methodologies; reduce financing costs by providing a project with a Measurement and Verification Plan (M&V Plan) standardisation, thereby allowing project bundling and pooled project financing.

  5. Pinch analysis - Wikipedia

    en.wikipedia.org/wiki/Pinch_analysis

    In order to reduce capital cost, in practice a minimum temperature difference (Δ T) at the pinch point is demanded, e.g., 10 °F. It is possible to estimate the heat exchanger area and capital cost, and hence the optimal Δ T minimum value. However, the cost curve is quite flat and the optimum may be affected by "topology traps".

  6. Cost database - Wikipedia

    en.wikipedia.org/wiki/Cost_database

    The most basic element of a cost estimate and therefore the cost database is the estimate line item or work item. [3] An example is "Concrete, 4000 psi (30 MPa)," which is the description of the item. In the cost database, an item is a row or record in a table (of items) and the description is a column or field for that record.

  7. COCOMO - Wikipedia

    en.wikipedia.org/wiki/COCOMO

    The Constructive Cost Model (COCOMO) is a procedural software cost estimation model developed by Barry W. Boehm. The model parameters are derived from fitting a regression formula using data from historical projects (63 projects for COCOMO 81 and 163 projects for COCOMO II).
