Featured Project Databases
- UNEP-Risoe Centre for Energy, Climate and Sustainable Development CDM/JI Pipleline Analysis and Database
- The UNEP Risoe CDM/JI Pipleine Analysis and Database is a website that provides analysis results and lists of projects submitted to the Clean Development Mechanism and Joint Implementation Kyoto Protocol mechanisms of the carbon market. The website includes lists of renewable energy and energy efficiency projects organized by country and project type. The lists can be downloaded as Excel spreadsheets. The website also includes a library of CDM guidebooks that can be downloaded as PDF files.
- HOMER is a free Windows-based optimization model designed to help decision-makers and engineers choose among the wide range of options for small power systems, including power systems based on conventional and renewable technologies. HOMER can model standalone or grid-connected systems, and systems based on a single technology or hybrid power systems. It aids in the evaluation of systems that may include fuel-based generators, solar panels, wind turbines, micro-hydro systems, with or without electric storage. HOMER requires information about equipment costs and energy resource data to run. HOMER includes component libraries for a selection of wind turbines and batteries.
- RETScreen Clean Energy Project Analysis Software
- RETScreen is a Microsoft Excel-based model for decision makers to evaluate clean power projects using renewable energy, cogeneration, district energy, heating and cooling technologies as well as energy efficiency projects. The software is intended for energy professionals involved in analyzing the financial viability of potential projects, and allows for analyzing energy production and/or savings, project costs, emission reductions, financing options and sensitivity/risk analysis. The software is available for free, includes extensive training materials, and is available in 35 languages. RETScreen provides access to global climate and equipment datasets. RETScreen includes databases of equipment and links to weather data.
- Solar Advisor Model
- The Solar Advisor Model (SAM) is a free model that runs on Windows or Mac computers and models grid-connected solar electric power systems based on photovoltaic and concentrating solar power technologies. SAM can model flat-plate and concentrating photovoltaic systems, and parabolic trough, dish-Stirling, and power tower concentrating solar power systems. The model combines a performance and economic model to predict system output and estimate project costs under different financing and incentive scenarios. SAM requires some knowledge of solar technologies and renewable energy project financing, installation and operation cost information, and weather data for the project location. Free weather data for SAM is available in the Internet for many locations around the world. SAM includes a set of weather files for U.S. locations, and component libraries for a selection of system components, including modules and inverters for photovoltaic systems, and turbines and other components for concentrating solar power technologies.
- PVWatts is a free, web-based model the predicts the performance and calculates the cost of energy of grid-connected photovoltaic power systems using a derating factor to represent the performance of the entire system. Version 1 includes locations outside of the U.S. Version 2 uses a map tool to select U.S. locations.
- EnergyPlus is building simulation software that models the performance a building's heating, cooling, lighting, ventilation, and water systems. The model is designed to help building engineers and architects size HVAC equipment for new buildings and for retrofit projects. The analyst provides a description of the building with information about indoor climate requirements, and the model calculates the building's heating and cooling loads and energy consumption. The model requires both a high level of technical knowledge of building systems and of computer modeling.
- Energy-10 is Windows-based building energy and simulation model available for purchase from the Sustainable Buildings Energy Council. The model was developed by the National Renewable Energy Laboratory, and allows architects and building engineers to analyze energy cost and savings of different building design options, including daylighting, passive solar heating and cooling, photovoltaic systems, natural ventilation, building insulation, and use of high-performance elements such as windows, lighting systems, and mechanical equipment.
