“…As seen in Fig. 5, while 1 kg wood can store 9 kg CO 2 , the rest of building construction materials positively contribute to the CO 2 emissions, particularly the aluminium has a significant footprint on the environment by releasing 27 kg CO 2 per kg [79,80].…”

“…Other vertical farms have been built in Korea, Japan, the USA and Sweden [98-100, 102]. Singapore, one [79,80] of the most densely populated countries, is considering a futuristic "floating vertical farm" designed by Forward Thinking Lab of Barcelona [103]. The system basically consists of looping towers that could float in local harbours, providing new space for year-round crops.…”

“…4 Benefits of using wood as building construction material. Legend -Wood is the only material with a negative CO 2 balance; each cubic metre of wood sequestrates on average 0.8 to 0.9 tonnes CO 2 [79,80]. Building with wood could play a vital role in reducing air pollution and global warming.…”

Massive growth is threatening the sustainability of cities and the quality of city life. Mass urbanisation can lead to social instability, undermining the capacity of cities to be environmentally sustainable and economically successful. A new model of sustainability is needed, including greater incentives to save energy, reduce consumption and protect the environment while also increasing levels of citizen wellbeing. Cities of the future should be a socially diverse environment where economic and social activities overlap and where communities are focused around neighbourhoods. They must be developed or adapted to enable their citizens to be socioeconomically creative and productive. Recent developments provide hope that such challenges can be tackled. This review describes the exciting innovations already being introduced in cities as well as those which could become reality in the near future.

“…In a district heated building the delivered district heat is metered at the heat exchanger. Here, there is a heat loss of about 5% [39] which is not used in the building as the heat exchanger is usually located at a place without any need for heat. Hence, the heat demand of the Pr-DH or Gr-DH buildings is estimated to be 95% of the delivered district heat.…”

“…Existing studies on the properties of CLT have shown that CLT construction has advantages in fire resistance, thermal performance, and the potential for carbon sequestration in the building structure [33][34][35][36][37][38][39][40][41][42][43]. Other studies indicates that CLT buildings are structurally sound against the risk of collapse under a Maximum Credible Earthquake [34].…”

Energy Sustainability of Bio-Based Building Materials in the Cold and Severe Cold Regions of China—A Case Study of Residential Buildings

et al. 2020

The aim of this research is to investigate the energy sustainability of cross-laminated timber (CLT) and straw residential buildings in the Cold and Severe Cold Regions of China. In the study, three building materials, namely reinforced concrete (RC), CLT, and straw bale, are used separately to design the building envelope in reference residential buildings in different climate zones. The energy consumption during the operation phase of these buildings is then simulated using Integrated Environmental Solutions—Virtual Environment software (IES-VE). The results show that both CLT and straw buildings are more efficient than reinforced concrete with a reduction in energy consumption during the operational phase. Overall, the calculated heating energy-saving ratios for CLT buildings in Hailar, Harbin, Urumchi, Lanzhou, and Beijing are 3.04%, 7.39%, 7.43%, 12.69%, and 13.41%, respectively, when compared with RC. The calculated energy-saving ratios for heating in straw buildings in comparison with RC in these cities are 8.04%, 22.09%, 22.17%, 33.02%, and 34.28%, respectively. The results also reveal that a south orientation of the main building facade results in approximately 5% to 7% energy reduction in comparison with east or west orientations, and as the building height increases, energy consumption decreases gradually. Although RC is the most frequently used building material in Cold and Severe Cold regions in China, as bio-based building materials, there is great potential to promote CLT and straw bale construction in view of the energy sustainability features.
