  • Building Envelope Design for Optimization: Leveraging BEM and Energy Simulation Capabilities

    When it comes to energy efficiency in building and occupant structures like Homes, Offices, Healthcare facilities, etc, the first things that come to your mind are probably the efficiency and use of HVAC systems and the lighting within a facility. However building envelope is arguably the first place to start with as this is ...

  • 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 ...

  • Thermal impact of sinking residential buildings in hot regions – Kuwait as a case study

    This paper is concerned with improving residential building thermal performance at early design stage. The modification considered in this work was based on reducing external heat gain via sinking the building or part of it. Three scenarios were proposed of which the most acceptable one was thermally analysed. The analysis was based on integrated dynamic simulation of the whole building thermal ...

  • A novel underground solar thermal heat storage unit cum heat exchanger for non air-conditioned buildings

    A novel passive space conditioning configuration is presented, integrating a Solar Collector System, Underground Storage Tank and Novel Heat Exchanger. This Underground Solar Thermal Heat Exchanger (USTHE) provided improved sensible heating/cooling of air by employing a Novel Heat Exchanger (NHX). The dynamic performance of the storage tank in USTHE is modelled using the finite difference method ...

  • Carbon tax and energy resource in Indian power sector

    Abstract: Global warming is a universal problem nowadays. The recent United Nations Climate Change Conference in Copenhagen was partially successful because all participating countries realised the damages caused by greenhouse gas (GHG) emissions and promise to mitigate in the future course of time. India has also promised to reduce 20% to 25% of these emissions up to the year 2020. To implement ...

  • Transient analysis of pressure and temperature of fluid into AP1000 reactor containment during DECL accident with several volumes modelling

    Since the accidents at Three Mile Island and Chernobyl, more stringent requirements have been imposed on the containment system for full replica nuclear power plant simulators. The simulation must be able to accurately respond under all normal operations and especially under abnormal conditions, including leaks and breaks of any size in any location in the reactor building. This paper presents ...

  • Define ‘green’ please

    Describing a building as ‘green’ makes a lot of people cringe. The word is overused. And what does it mean exactly? Serious efforts are underway to move away from the hype and offer a more specific analysis of a building’s energy performance. Think nutritional labels for food, except in kilowatt-hours instead of calories. In fact, more than 50 national, regional and local ...

  • The Effectiveness of Combined heat and Power Solar Water Heating Systems

    Abstract: Solar water heating in residential and commercial buildings is often provided by integrating a large number of domestic thermosyphon solar water heaters. The economic effectiveness of solar Domestic hot water heating systems depends mainly on its types and configurations. Thereupon in this paper, simulation models have been presented for the modeling of thermal and electrical ...


  • Want to improve wind and solar power? Bring them together

    By combining intermittent renewable energy sources through hybrid projects, developers are taking advantage of the strengths of each. What’s keeping solar and wind power from fully taking over the electric grid? For starters, the sun only shines during the day. Wind blows intermittently, is ...

  • Solar`s Time to Rise and Shine.

    Photovoltaic efficiency records are being shattered, thanks to recent advances in materials science. Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. The simulator flashed a 2.5 millisecond pulse of light, and 19 mirrors reflected the ...

  • Power Of Partnerships In Sports Greening

    Professional and collegiate sports teams, and their leagues, develop vital partnerships to green their venues, operations and supply chain, while engaging fans to adopt sustainable behaviors. An overarching theme of the 2016 Green Sports Alliance Summit, June 28-30 in Houston, Texas, is The Power of Partnerships. “Throughout the program speakers will share how unique partnerships are ...
