  • Building Energy Modeling 101: HVAC Design and Operation Use Case

    A great deal of energy use in buildings goes toward heating, ventilation, and air-conditioning (HVAC). In 2015, HVAC consumed 15.5 quads. The first step in reducing HVAC energy use is reducing heating and cooling load—i.e., the amount of heat that needs to be added to or removed from a building—typically by reducing heat from equipment and lighting; minimizing unnecessary ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • Energy efficiency policies and measures in Hungary

    The article analyses Hungarian energy efficiency policies and measures in different sectors. The energy efficiency measures are ranked in the following sectors: energy, industry, transport, household and tertiary. The primary and final energy intensities and the energy efficiency index are examined in the frame of macroeconomic analysis. The energy consumption trends and the driving forces are ...

  • Aerial radiological systems, measurements and analysis

    This document describes data collection systems and procedures used by the US Department of Energy Aerial Measuring System (AMS) in response to a radiological emergency. The discussion is split into two parts: (1) those systems used on the fixed-wing aircraft and (2) those systems used on the helicopters. This split is principally caused by the final use of the data from each system. The ...

  • Measurement uncertainty

    The IAEA/WHO Network, through Secondary Standards Dosimetry Laboratories (SSDLs) designated by the Member States, provides a direct linkage of national dosimetry standards to the international measurement system (SI, for Système International). Through the proper calibration of field instruments by the SSDLs, these measurements are traceable to the Primary Standards Dosimetry Laboratories (PSDLs) ...

  • Measuring Greece's progress towards energy sustainability

    Energy is essential to economic and social development and improved quality of life. The European Union (EU) constitutes one of the world's largest energy consumers. The EU members include – among others – Germany and Greece, two countries with large disparities/differences in their energy systems, yet with certain similarities. The role of indicators that can measure all the future changes is ...

  • Testing and developing energy harvester systems for operation of energy-self-sufficient measurement and control units in drinking water supply

    In recent years, wireless measurement and control units have become more popular for monitoring water distribution systems in the drinking water supply. Electric power supply for a higher number of devices through fixed connections to the public electrical grid is technically complex and requires large investments. Powering monitoring devices, which are installed in areas where electrical ...

  • Measuring enthalpy to calculate efficiency

    Summary This application note describes in detail how you can calculate the gain in efficiency of a direct exchange air conditioning system before and after treatment with the SRA. The physics underlying the method are explained. Introduction Air comprises gasses and water moisture. The gasses are mostly nitrogen (78%) and oxygen (21%). The amount of water ...

  • How sustainable is the German energy system? Introducing the Indicator for Sustainable Development (ISD) as a new measuring concept

    For around 20 years, the sustainability concept and its implementation have been discussed by society at large (Kobiowu et al., 2005; Goldblatt, 2005; Marechal et al., 2005; Backstrand, 2006; Spangenberg, 2005) and, among others, by the green economics community (Lunn, 2006; Kennet and Heinemann, 2006b; Dobson and Bell, 2005a; Barry, 2005). Sustainability is regarded as a solution to society's ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Measurements and Standards to Support Increased Energy Efficiency and Reduced Environmental Impact

    “The world is facing twin energy-related threats: that of not having adequate and secure supplies of energy at affordable prices and that of environmental harm caused by consuming too much of it.” Daniel Hecker, economist, Bureau of Labor Statistics, July 2005 Buildings in the U.S. consume 72 percent of all electrical energy produced in this country. Emissions associated with ...

  • Plan B efficiency and conservation measures drop energy demand by 2020

    Projections from the International Energy Agency show global energy demand growing by close to 30 percent by 2020, setting the stage for massive growth in the carbon dioxide emissions that are warming our planet. But dramatically ramping up energy efficiency would allow the world to not only avoid growth in energy demand but actually reduce global demand to below 2006 levels by 2020. We can ...

  • Measuring diversion, recycling progress

    ONE OF the first sessions at the 23rd Annual BioCycle West Coast Conference next month in San Diego is titled “Documenting Waste Diversion.” When the State of California adopted its AB 939 recycling law in 1989, it established a 50 percent waste diversion goal by 2000. Jurisdictions failing to meet that goal would be subject to fines. A number of other states adopted diversion or recycling goals ...

  • Implementing an Energy Management System in a School

    Implementing an energy management system in a school can reduce expenditure on energy and minimise waste. This can be both as a result of on-site management/operational issues as well as through investment in energy saving (no-, low-, medium- or high-cost measures). Carbon emissions can be reduced through the ...

  • New technologies for measuring the humidity of biomass

    Methods applicable to a great variety of solid biofuels In recent years, systems have sprung up which use near infrared X-ray (NIR) spectroscopy, radio frequency (RF) and microwave spectroscopy as alternatives to the traditional method of measuring humidity by weight difference in the fuel burner. What these methods have in common is that they can be used for a great variety of solid biofuels, ...
