The calculator gives an indicative cost for connecting a project to an existing water main.

The AVoided Emissions and geneRation Tool (AVERT) evaluates how energy policies and programs such as energy efficiency, renewable energy, and electric vehicles lead to changes in emissions of particulate matter (PM2.5), nitrogen oxides (NOX), sulfur dioxide (SO2), carbon dioxide (CO2), volatile organic compounds (VOCs), and ammonia (NH3) from electric power plants at a county, state, or regional level. AVERT is a free tool designed to meet the needs of state air quality planners, energy officials, public utility commission staff, environmental agency staff, professionals in the clean energy field, people working on climate planning, and other interested stakeholders.

This spreadsheet allows the user to calculate parameters relevant to techno-economic performance of a two-step absorption process to transport low temperature geothermal heat some distance (1-20 miles) for use in building air conditioning. The parameters included are (1) energy density of aqueous LiBr and LiCl solutions, (2) transportation cost of trucking solution, and (3) equipment cost for the required chillers and cooling towers in the two-step absorption approach. More information is available in the included public report: "A Technical and Economic Analysis of an Innovative Two-Step Absorption System for Utilizing Low-Temperature Geothermal Resources to Condition Commercial Buildings"

ENERGY STAR® is the government-backed symbol for energy efficiency. The blue ENERGY STAR label provides simple, credible, and unbiased information that consumers and businesses rely on to make well-informed decisions. With this powerful tool, you can estimate your building’s GHG emissions, support GHG emissions inventories, evaluate emissions under local building performance standards, and forecast the impact of changes in building efficiency and energy procurement.

This calculator is a handy tool for interested parties to estimate two key life cycle metrics, fossil energy consumption (Etot) and greenhouse gas emission (ghgtot) ratios, for geothermal electric power production. It is based solely on data developed by Argonne National Laboratory for DOE's Geothermal Technologies office. The calculator permits the user to explore the impact of a range of key geothermal power production parameters, including plant capacity, lifetime, capacity factor, geothermal technology, well numbers and depths, field exploration, and others on the two metrics just mentioned. Estimates of variations in the results are also available to the user.

ICAO’s Application Programming Interface (API) Data Service contains the raw data collected and processed from different aviation authorities, Member States, other international organisations and NGOs. Registration required to get an API key with 100 free calls to test the ICAO API service. Additional calls require a paid subscription.

ICAO has developed a methodology to calculate the carbon dioxide emissions from air travel for use in offset programmes. The methodology applies the best publicly available industry data to account for various factors such as aircraft types, route-specific data, passenger load factors and cargo carried. The ICAO Carbon Emissions Calculator allows passengers to estimate the emissions attributed to their air travel. It is simple to use and requires only a limited amount of information from the user. ICEC is the only internationally approved tool to estimate carbon emissions from air travel.

Impact is a digital visualisation tool that helps you understand your community’s carbon footprint. It works for parishes, wards and local authority areas. It helps identify the areas where taking action to tackle climate change can make the biggest difference.

IRENA Avoided Emissions Calculator1 provides an estimate of the emissions that have been avoided due to a country’s uptake of renewables in a given year. This value will vary greatly depending on the nonrenewable mix that has been replaced by renewables. This calculator therefore can only be used to provide a general indication of avoided emissions for various scenarios rather than an absolute number which will require further information on baseline electricity use and technology displacement options.

The NABERS ESC Estimator will help you understand whether your building is eligible to participate in the NSW Energy Savings Scheme (ESS) under the NABERS baseline method. It will also provide an estimation of how many ESCs your building could potentially generate by reducing its energy consumption. For this tool you will need an accurate estimation of your energy consumption and your predicted NABERS Energy rating. To generate ESCs, you will need to assign an Accredited Certificate Provider (ACP) before the end of the rating period. Note: results predicted by the ESC Estimator are an indication only.

NABERS has released prediction tools to support building owners in understanding the impact of NABERS Energy ratings on individual assets across different sectors. The tool includes forecasted scenarios estimating the impact on ratings in 2025 and 2030. The benchmarks which calculate NABERS Energy ratings are updated every five years with the next update scheduled for 2025. These changes are implemented in a way that does not affect the average rating of the sector at that time.

Use the NABERS rating calculators to get an idea of how well your building or tenancy is performing. Results are an indication only and cannot be promoted or published.

NABERS reverse calculators give you an indication of the maximum amount of energy and water your building can use to achieve your desired rating.
