  • Building on tradition

    A new technology is making a name for itself in potable water filtration. And, according to AMT Systems, it is the most cost-efficient advance since the introduction of the dual media filter. Your filters need to be washed every day. What would your energy, water and waste treatment saving be if they only required washing every four or five days? You need to increase the output of the works. Are ...

  • Nation Building

    Will Canada bond together as one happy family to build an east-west transmission grid to carry energy to one and all? Is it even a good idea? Just over 120 years ago this country was bounded together by Sir John A. MacDonald’s national dream of a transcontinental railway. Now some politicians are promoting another national dream – the construction of an east-west transmission grid that would meet ...

  • Analysis of buildings' energy consumption by means of exergy method

    Among the objectives of the Directive 2002/91/EC and of the Council "Energy performance of buildings", Energy Performance of Building Directive (EPBD) the energy certification of buildings represents a fundamental role. The method here described starts from the LowEX tool, previously developed in the IEA ECBCS Annex 37 framework. By using the exergy approach, new (non-economic) indices could be ...

  • Energy, exergy, thermoeconomic and sustainability analyses of a building heating system with a combi–boiler

    The energy, exergy, thermoeconomic and sustainability analyses are applied to the building heating system with a natural gas–fired combi–boiler. The building area is considered as 90 m². Furthermore, the design and analysis of the natural gas installation of the building are done. Two different methodologies (Fine–HVAC and LowEx analyses) are used for energy analyses (heat loss and demand) of the ...
