Preface
On 1 January 2016, the 17 Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development officially came into force. Over the next fifteen years, with these new Goals that universally apply to all, countries will mobilize efforts to tackle climate change while ensuring that no one is left behind. The SDGs, also known as Global Goals, build on the success of the Millennium Development Goals (MDGs). The new Goals are unique in that they call for action by all countries, poor, rich and middle-income to promote prosperity while protecting the planet. The aim of the SDG 7 is to ensure access to affordable, reliable, sustainable and modern energy for all. In order to achieve this goal, it is very important to reduce building energy consumption through positive technologies.
Through a lot of researches in the past, it has been pointed out that a high quality of urban environment can not only effect the thermal quality of outdoor space, but also effect the energy consumption of standalone buildings through so-called microclimate conditions. However, it was still lack of researches on the exact connections between urban environment and standalone building energy consumption under different climate types.
This book focused on the analysis methodologies to evaluate the thermal comfort qualities of urban environment and energy saving potential of different active or passive building energy conservation technologies. The book is funded by National Natural Science Foundation project (No. 51108185 and No. 51778235), natural science fund of Guangdong Province (No. 2016A030313513), State Key Laboratory of Subtropical Building Science fund project (No. 2013KB24) and Guangzhou development and reform commission energy-saving special fund project (Technology research of regional energy based on the energy cascade utilization), Basic scientific research business expenses of South China University of Technology (No. 2015ZM013).
The author would like to acknowledge the contribution of Prof. Qinglin Meng and Prof. Lihua Zhao from South China University of Technology, Prof. Moncef Krarti and Prof. John Zhai from University of Colorado at Boulder.
