Both the increasing demand for comfort levels and growth in population are facts that assure that the energy demand in buildings will keep growing in the future. Heating, ventilation and air conditioning systems (HVAC systems) are the principal users of this total energy demand, where percentages over 50% have been reached. Air conditioning is essential to maintain the thermal comfort inside the buildings, and for this reason, innovative cooling systems should be analysed in order to reduce and improve energy usage of these systems.   The aim of this thesis is to explore the viability and limi

With a water availability of less than 100 m3 per capita and year, Jordan is suffering extreme water-scarcity. To its intrinsic limited water resources more pressure is being added every year as a result of socioeconomic factors, such as the accelerated population growth, and a reduction of rainfalls and increase of evaporation as consequence of climate change. What is more, the poor condition of the water system together with a considerably high water consumption for irrigation are not helping in such drastic situation. In a country with scarce surface water, groundwater is the main resource.

This thesis will explore this and other findings from a qualitative evaluation of the Rock River Coalition (RRC) citizen-based stream monitoring project in Dane County, Wisconsin, USA. These findings are the culmination of 47 semi-structured interviews with decision-makers from seven client-identified categories and participant observations of board meetings and other watershed groups. Interview questions focused on current strategies

Abstract:
Energy and environmental impacts are two factors that will influence urban region composition in the near future. One emerging issue is the effect on water usage resulting from changes in regional or urban transportation trends. With many regions experiencing stresses on water availability, transportation planners and users need to combine information on transportation-related water consumption for any region and assess potential impacts on local water resources from the expansion of alternative transportation modes. This thesis will focus on use-phase water consumption factors for multiple ve

A redução das perdas em sistemas de distribuição de água tem se tornado, além de uma questão ética, um determinante da eficiência e mesmo da sobrevivência das concessionárias destes serviços. A quantificação e determinação da natureza das vazões perdidas, que possuem relação íntima com as pressões de operação, são aspectos que ainda merecem análises mais profundas e práticas. Os parâmetros do modelo pressão-vazamento permitem o detalhamento das perdas físicas e foram obtidos por meio de calibrações para um setor de distribuição de água da cidade de Piracicaba, SP, em padrões hidráulicos distin

Les digestats des boues d'épuration (SSD) et les digestats de la fraction organique des déchets ménagers (OFMSWD) ont été récemment considérés comme des sources potentielles pour la production de biochars en raison des quantités grandissantes de digestats solides restant à la fin de la digestion anaérobie. La pyrolyse des digestats solides est connue comme une technique pour promouvoir le recyclage des déchets organiques et générer des bio-produits à valeur ajoutée (i.e. biochar).

Syftet med detta examensarbete är att utforska möjligheten att minska resurssvinnet vid utförande av en så kallad clean-in-place-rengöring. Arbetet svarar på frågor gällande de möjligheter som finns att effektivisera rengöringsprocessen alternativt att minska medieförbrukningen genom att förkorta sköljtider. Den huvudsakliga metoden som arbetet baseras på är faktorförsök genom försökplanering. Detta är en metod för att strukturera försök med flera korrelerande faktorer. De faktorer som har förändrats med mål att göra resurseffektiviseringar är en minskning av lutlösningstemperatur för rengörin

One of the aims included in the United Nations Millennium Development Goals is to decrease the number of the world’s population without access to sanitation and water that is safe, by half by the year 2015. The use of water that is not safe for consumption leads to water–related diseases. For the purpose of this study gastro–intestinal disease was redefined as diseases of the gastro–intestinal tract caused by pathogens that spread via contaminated drinking water, poor sanitation and inadequate hygiene.

Abstract:
Over the last couple of decades, sustainability has gained importance in the business world, and a concept that has often been used as a prime example of how to deal with today’s environmental problems is circular economy. Even though the topic is relatively new, there has already been quite some debate about its actual advantages and disadvantages, and while there is as of yet no consensus, the majority argues that the application of circular economy practices will be beneficial for the environment. Which is exactly what this research has attempted to ascertain by looking at 78 firms from a w

Abstract:
Groundwater is often the most important source of drinking water. In recent decades, the environmental threats to this resource have increased dramatically, because of pollution, over usage and disturbed water balances. Climate change will affect the groundwater in coastal areas by sea-level rise and changes in precipitation and temperature. If seasonal variations in groundwater recharge and groundwater reservoirs changes it could lead to problems for drinking water supplies.  In coastal areas and archipelagos, there is a general lack of groundwater because of thin soil covers and limited stor
