SIMEA Stato dell’arte energetica degli edifici 92 Doc.No 20100610.SIMEA.MR.03 Versione 1 "More Energy Efficient". From this point users can copy and revise up to seven more schemes to more precisely represent their building and to test various energy design alternatives. Floor plans can be easily drawn in using HEED’s fill-in-the-squares technique. Windows can be clicked and dragged to their correct size and location on each façade. The building can be graphically rotated to its correct orientation (see screen shots). The Basic Design information is input by click and drag or by selecting from check lists. The Advanced Design inputs are tabular inputs for all variables in the program including thermal characteristics, dimensions, schedules, etc. 1.3.4.6. Output HEED is unique in that all of its performance data is presented graphically, in a wide array of formats. The basic output is a bar chart of fuel and electricity annual costs using local utility rates for up to nine different schemes. This bar chart can also show comparative annual energy consumption and the CO2 production, and total annual (site) energy consumption. Advanced outputs includes 3D plots for each hour of dozens of different variables including heat gain an loss for sixteen elements of the building's total load, plus outdoor and indoor air temperatures, air change rate, furnace and air conditioner outputs, power for lights and for fans, and gas and electricity costs. 1.3.4.7. Computer Platform HEED runs on all versions of Windows from 95 to Vista, and also on Mac OS 10.2 or later. 1.3.4.8. Programming Language HEED graphic user interface is written in Java and C++. The Solar-5 computation kernel is written in Fortran. 1.3.4.9. Strengths HEED's strengths are ease of use, simplicity and clarity of input data, a wide array of graphic output techniques, computational speed, and the ability to quickly compare multiple design alternatives. It can calculate the window-specific daylight reduction of electric lighting loads. It includes an intelligent wholehouse fan thermostat and window-dependent operable solar controls. HEED calculates the air pollution implications of design decisions. It can automatically manage up to nine schemes which can be assembled into any number of projects. 1.3.4.10. Weaknesses Works best for single-zone buildings, although it can aggregate up to four adiabatic zones. It has generic HVAC systems. Operating schedules in the current version are limited to residential buildings. It contains utility rates for California’s five major utilities, but they can be user-modified for most types of rate structures. HEED comes with climate data for all 16 California Climate Zones, both of which can be accessed for hundreds of California zip codes. HEED can also directly read Energy Plus climate data for over a thousand sites around the world (see read-usa.txt).
SIMEA Stato dell’arte energetica degli edifici 1.3.5. HOMER 93 Doc.No 20100610.SIMEA.MR.03 Versione 1 Evaluates design options for both off-grid and gridconnected power systems for remote, stand-alone, and distributed generation (DG) applications. HOMER's optimization and sensitivity analysis algorithms allow you to evaluate the economic and technical feasibility of a large number of technology options and to account for variation in technology costs and energy resource availability. HOMER models both conventional and renewable energy technologies. 1.3.5.1. Validation/Testing Validation results are available upon request. 1.3.5.2. Expertise Required Basic familiarity with Windows and the technology of small power systems. 1.3.5.3. Users 3000 users in 142 countries. Approximately 1/3 are in the U.S., 1/3 in other OECD countries, and 1/3 in the rest of the world. 1.3.5.4. Audience System designers, rural electrification program planners, policy, market and technology analysts for distributed and small power technologies. 1.3.5.5. Input Load profiles for the application of interest, renewable resource data (although the software makes some of that available), local installed costs for technology components. 1.3.5.6. Output HOMER has a huge quantity of output data in tabular and graphic format, including sensitivity analyses, hourly operational data and comparative economics for competing system architectures. 1.3.5.7. Computer Platform Windows 1.3.5.8. Programming Language Visual C++ 1.3.5.9. Strengths Compares different technologies including hybrids. Considers storage. Considers seasonal and daily variations in loads and resources. Designed as optimization model for sensitivity analyses. Performs dozens of 8760 hour annual simulations per second. Great graphical outputs. 1.3.5.10. Weaknesses Does not consider intra-hour variability. Does not consider variations in bus voltage.
