Farming is very popular in Tohoku Region. Especially the yield of rice in this region is more than 10%of that in Japan. However, farmers have a problem with its storage in winter and summer. In general,rice should be harvested in autumn, and be stored until the harvest next year. To store it in summer,electric refrigerators are generally used and they cost a couple of million yen every year.
There is an obvious and indisputable need for an increase in the efficiency of energy utilisation inbuildings. Heating, cooling and lighting appliances in buildings account for more than one third of theworlds primary energy demand. In turn, building stock is a major contributor to energy-relatedenvironmental problems.
Mould can cause allergic, toxic or infectious reactions (Bardana 2003). The lack of quality standardsfor assessment and removal of indoors mould has caused the German Federal Environmental Office(germ: Umweltbundesamt, UBA) to issue several health-related guidelines (UBA 2002). This studyrecorded to what extend these recommendations has been realized by experts for assessment andremoval of indoors mould damage in Greater Bielefeld, Germany. The expert companies conductedeither assessment (inspectors) or removal (craftsmen) or both, assessment and removal, of mould(case managers).
Decomposition of toluene in air was studied by dielectric barrier discharge (DBD) on the one hand aswell as UV light as assistance to DBD on the other hand.Input energy to reaction chamber, flow rate of contaminated air, and concentration of toluene werestudied as parameters influencing on the decomposition rate of toluene by two methods.Increasing the input energy from 2.8 kV to 4.2 kV at flow rate 1 SLM was increased the decompositionrate of toluene from 3.5% to 10%.
The growing worldwide demand for less polluting forms of energy has led to a renewed interest in theuse of micro combined heat and power (CHP) technologies in the residential sector. Micro CHP is thesimultaneous production of heat and power in a single building based on small energy conversion units.The heat produced is used for space and water heating and possibly for cooling, the electricity is usedwithin the building.In this paper, two typical CHP types for a residential building are analyzed, namely ECOWILL gasengine plant and LIFUEL fuel cell plant.
Since our earth has finite material resources and biological capacity, human must live within thecarrying capacity on the earth.As we exceed the carrying capacity of the earths ecosystem over thetime they stressed, then go into decline and finally collapse. They are expanded further than renewed.The construction and operation of built environment contribute to the environmental loads. Those whodesign and purchase building have little or no methods to asses the environmental impact of theiractions.
This paper first introduces the concept of “exergy”, which quantifies what is consumed by any working systems from man-made systems such as heat engines to biological systems including human body. “Exergy” balance equation for a system can be derived by c
A distributed energy system in Kitakyushu Science and Research Park (KSRP) has been introduced since April 2001. In this paper, the system’s running situation was analyzed by using the recorded data in 2003. Generating electricity, heat recovery efficienc
A study from 2005-2007 has been undertaken of 18 ‘low-energy’ dwellings in Milton Keynes, UK, originally monitored for temperature and energy consumption from 1989-1991. Results were compared under standardized daily external conditions of 5ºC. The follow
