  • 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 ...

  • Application of a modified version of RAMS model to simulate the flow and turbulence in the presence of buildings: the MUST COST732 exercise

    A modified version of the atmospheric model RAMS6.0 is used to simulate the flow in the MUST experiment, within the framework of the COST732 Action. A standard version of the k-ε turbulence closure model and its renormalisation group version, RNG k-ε, were implemented in the model. Simulations were performed to test the suitability of using the model to reproduce the flow and turbulence in the ...

  • 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 ...

  • Stocking Your Green Building Toolkit

    1. Introduction Designing, constructing and operating environmentally friendly buildings can be a lot more complex than it seems, especially when it comes to materials selection. We would all like simple measures or rules of thumb that would make the selection process easy, but they are hard to come by, if they exist at all. The reality is that we are constantly forced into a balancing act, ...

  • Fine-tuning acoustic isolation in buildings

    ACCIONA Infrastructure is ranked among the leading construction companies in the world - and is recognised for implementing the most advanced and innovative technology.  As research and design is vital to keep the company at the cutting edge in relation to technological developments, ACCIONA Infrastructure created a team to analyse noise and vibration. Where traditional ...

  • Life Cycle Assessment applications in the building sector

    A Life Cycle Assessment (LCA) tool has been developed to evaluate environmental impacts of building projects, from construction until demolition. The operation phase is essential, particularly energy processes: therefore LCA is linked to thermal simulation. Several alternatives can be studied. The results, in the form of environmental indicators (e.g., energy and water consumption, contribution ...

  • Renovating vs. Building New: The Environmental Merits

    This presentation focuses on the environmental implications of two case study projects involving extensive renovation and rehabilitation of older Canadian buildings to serve new functions. Both of the case study projects were submitted as ...

  • Measures to weaken the influence of solar radiation on peak cooling load in office buildings

    Using the building energy simulation program EnergyPlus, the authors studied and analysed measures to weaken the influence of solar radiation on peak cooling load in office buildings. The peak cooling reduction effect on exterior wall outside surface solar radiant absorptance and different kinds of exterior window constructions were analysed by simulation. The results show that using a low solar ...

  • A collaborative platform for sustainable building design based on model integration over the internet

    Considerable potential exists for reducing life cycle environmental impacts of buildings in Japan. While energy consumption during the operation stage of a building's lifetime is usually dominant, indirect energy use and pollutant emissions associated with production and disposal of building materials during construction and demolition are significant. For sustainable building design, ...

  • 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 ...

  • Environmentally adjusted domestic product and emission control policies; a dynamic simulation modelling approach: an example from the French carbon dioxide emission prospects

    This paper aims at defining some ecologically adjusted aggregates with a view to building a "green" accounting framework. The model used for the research is based on both systems dynamics modelling and energy input–output analysis. We consider that this combined method has the interesting property of accurately tracing the physical foundations of economic sectors' interactions, as well as their ...
