  • Zoo-technical application of Ground Source Heat Pumps: a pilot case study

    Ground Source Heat Pumps are energy-efficient HVAC systems usually adopted in residential and commercial buildings. However the control of the thermal environment is required not only in spaces occupied by people, but also in intensive breeding farms, in order to maintain healthy conditions and to increase productivity. In the Italian livestock breedings, heating is usually provided by means of ...

  • Getting an air source heat pump from Better Planet – from first discussion to finished project

    Initial contact The initial contact is often on the phone and we try to establish if an air source heat pump makes sense from a financial and technical point of view. Heat pumps makes sense for most new built projects. For retrofits, heat pumps makes most sense for properties not connected to the gas grid. If you are connected to the gas grid, ...


  • Geothermal Heat Pump (GHP) - Case Studies

    Case Study: “GHP schools used approximately 26% less source energy per square foot of floor area,” according to an evaluation of Lincoln, Nebraska schools by the Department of Energy. The report concludes that the schools using GHP technology “outperform others in the school district.” Case Study: Annual electrical consumption in Fort Polk ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Case-study - Utilising waste heat for water production and climate control

    Water purification is needed to produce high quality water for consumption, agriculture and industrial needs. Conventional water treatment processes, like distillation and reverse osmosis, consume vast amounts of energy. However, there is a large potential for significant reductions in energy consumption and CO2 emissions in this sector. It can be achieved by the exploitation of waste heat for ...

  • Using electricity to save the planet

    When it comes to energy efficiency, it used to be the big guys that mattered. Policymakers and market leaders focused on manufacturers, refiners and others that gobbled up lots of kilowatt hours.It’s not surprising. Manufacturers create bang for the buck. Better motors, refrigeration or combined heat and power can lead to six-digit dollar savings — far more impressive than the $10 per month an ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • Closing the last Energy Leak

    The heat contained in wastewater is one of the last major untapped resources in the field of renewable energies, despite the fact that it may some day provide some 20% of the heating energy we need. This huge potential has been addressed by a Swiss engineering office, Rabtherm AG, which now supplies patented technology for generating energy from wastewater, used for heating or cooling buildings. ...

  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • The reference environment: utilising exergy and anergy for buildings

    The utilisation of exergy and anergy concepts for low exergy system design extends the potential of performance optimisation of buildings. We propose a new perspective for buildings and their external environment. It recognises exergy as the utilisable potential that maintains comfort inside relative to outside ambient conditions. It considers environmental heat sources as a form of transiting ...

  • The Italian Job

    Open loop systems abstract groundwater from one or more boreholes. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate well or body of water. The supply and return lines need to be placed far enough apart to ensure thermal recharge of the source. The key issues for open loop systems relate to borehole yields, licensing and, most importantly, ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • Case study - Keeping ethanol production green

    OVERVIEW Originally published in Pollution Engineering Magazine. In an effort to reduce the world’s dependence on fossil fuels, there has been a major push towards alternatives. Ethanol has been at the forefront of this movement because it reduces greenhouse gas emissions from automobiles and its production has a positive net energy balance. The homegrown fuel also ...
