The earth is experiencing the adverse effect of climate change. In response to growing global warming issues and the constant increase of energy prices, house-builders and housing manufacturers today are becoming more responsive to the delivery of net zero energy and carbon dioxide emission sustainable homes than ever. Within this context, the sustainability may also embrace housing economy and adequacy beyond the legitimacy in which the quality barely coincides with individuals' dynamic various needs, desires and expectations. Nevertheless, the housing industry's business operation tends to follow routines and the close system mode of operation often hinders the enterprises from adopting unfamiliar innovations which may be inevitable in realising the delivery and operation of socially, economically and environmentally sustainable homes. This book showcases the zero energy mass custom home (ZEMCH) design workshop experience, which engaged with a wide spectrum of hopes and fears around the design, production and marketing approaches to low cost housing developments in Brazil.
It is possible to define zero energy/emission buildings by various aspects.Energy consumption in operation phase of the buildings is the majority discussion in this field.EU s targets regarding climate change and energy for sustainable growth which were approved by European parliament include greenhouse gas emission reduction by 20%,increase in consuming of renewable energy resources by 20% and achieving 20% increase in energy efficiency for moving toward zero energy/emission buildings until 2020.The zero energy/emission buildings are gaining interest as renewable energy resources which help to capture green house gases emission, especially CO2 emission.By considering this fact that residential buildings consume 40% of total delivered energy in Sweden,the scientifically assessment of CO2 level in this country by residential sector on one hand and implementing new technologies for decreasing GHG emission in term of decreasing energy consumption on the other hand are very important. By knowing this fact that for producing 1KWh energy in Sweden around 40g CO2 emission is released,in two million Swedish single family houses it is possible to capture around 800000 tonnes CO2 emission
The necessity to reduce green house gas emission and growing difficulties in fossil fuel recovery raise great challenges for the scientific community to develop efficient, low cost alternative energy sources. Hydrogen is sought by many as a way to store and transport energy produced from renewable sources. As a fuel hydrogen produces only water on burning and is not toxic in any way. Photolytic processes are very attractive for hydrogen production due to the zero greenhouse gas emissions, however, they can be commercially used only if limitations related to low efficiency and poor stability can be resolved. In this work we describe a novel cell structure for stable photo electrochemical water splitting that can be prepared by electrodeposition from ionic liquids at high temperature. The deposition methods developed here provide low cost and efficient way to synthesise high quality semiconductors and their alloys. The concept presented in this work can potentially be applied to a variety of efficient, yet unstable systems to achieve efficient and long lasting water splitting.
