Abstract :
The Yangtze River Delta is a relatively developed area with many detached houses in the suburbs. Such detached houses are usually 1-3 stories high, mostly self-built by local people. Due to the lack of passive design guidance in the design and construction process, these houses' energy consumption is usually high. At present, residents in the area use air conditioners, fans, and other electrical equipment in their daily lives. This paper takes detached houses in the suburbs of Ningbo as the research objects, through performance simulation and big data mining of a large number of generated samples, and proposes a passive design strategy suitable for the local building form and envelope structure, which can guide local housing construction.

Abstract :
To investigate the changes of larch wood properties under the influence of long-standing exposure to the environment, the QUV accelerated weathering tester (fluorescent UV and condensation testers) was used to accelerate the weathering of wood within a given preset time, and the changes were studied by analogue simulation. The wood color changed noticeably under different weathering time, and it gradually darkened from light yellow to deep reddish brown. Scanning electron microscopic (SEM) analysis revealed that as the weathering time increased, the cell wall was broken, the pits were cracked, and the tracheids were damaged. The results of the energy spectrum analysis (O/C (oxygen/carbon)) showed an increasing trend in the ratio, indicating that the wood underwent an oxidation reaction induced by light. From the values of the two testing indexes and their change patterns with weathering time, the same trend was observed, with the values of modulus of elasticity (MOE) in static bending being greater than that in dynamic bending E-d (the dynamic modulus of elasticity). However, the variability of MOE was greater than that of E-d. A comparative analysis of the two detection indicators was performed. The relationship between the proposed combined correction E-d and weathering time was: y = 0.0000001017 t(2) - 0.0006 t + 9.77.

Abstract :
The wooden columns in timber structures of ancient buildings have column foot tenons of various sizes. The main reason for these differences is their use for different roof loads. Six full-scale specimens with different sizes of column foot tenon were designed and manufactured. The tree species used for the specimens was larch. The quasi-static test was conducted on the specimens that were used in timber structures of ancient buildings. The effects of column foot tenon size on the mechanical properties of larch wooden columns were studied. The moment-rotational angle hysteretic curves, moment-rotational angle skeleton curves, ductility, stiffness degradation, energy dissipation capacity, slippages between the wooden column and the plinth, and the damage of the column foot tenons were examined. The test results showed that the column foot tenon played an important role in the mechanical behavior of the wooden column under low-cycle reversed cyclic loading. The rotation of the column foot tenon improved the energy dissipation capacity of the wooden column. As the rotational angle of the column base increased, the column foot tenon had different degrees of damage. Different sizes of column foot tenon had their own advantages and hysteretic behavior.

Abstract :
Rapid urbanization has driven economic and social development, but it has also led to continued growth in building energy consumption. It is of great significance to ensure the user comfort while controlling the growth of building energy use. Accurate quantification of urban buildings' energy demand can support energy efficient and sustainable community design, assist urban morphology generation and optimization, building layout optimization, building shape and construction design, HVAC system optimization, assessment of the energy program and policy. In recent years, researchers worldwide have carried out research of urban scale energy consumption calculation methods from different perspectives, and encountered different technical difficulties. This paper provides a critical review on the energy modeling methods at urban neighborhood scale from the following three aspects: database, models and platforms. Through literature review, the authors indicate the advantages and limitations of current urban building energy calculation methods and tools, and propose the following possible approaches to improve the operational energy consumption calculation method for urban buildings: (1) develop micro-environment data generation methods that can be directly applied to energy consumption calculation of urban buildings; (2) improve the capabilities to collect, filter and convert the building information data by introducing the data mining technique; (3) introduce the cluster analysis and artificial intelligence technology to improve the speed of energy consumption calculation; (4) develop a visualization platform to realize real-time editing and calculating of urban design.

Abstract :
To accurately evaluate the dynamic elastic modulus (E-d) of wood in ancient timberwork buildings, the new materials of larch were used as the research object, and the stress wave nondestructive testing method was used to determine it. Based on nondestructive testing data, this paper proposed a method for predicting the E-d of larch using the principle of information diffusion. It selected the distance (D) from the bark to the pith in the cross-section of the wood and the height (H) from the base to the top in the radial section of the wood. The fuzzy diffusion relationships between the two evaluation indexes and the E-d were established using the information diffusion principle and the first-and second-order fuzzy approximate inferences in the fuzzy information optimization process. The calculation results showed that the dynamic elastic modulus model constructed by the information diffusion method can better predict the E-d of larch. The coefficient of determination between the measured value and the predicted value of the E-d was 0.861, they were in good agreement. The weights of the two influencing factors were 0.7 and 0.3, respectively, the average relative error of the fitted sample data was the minimum, which was 8.55%. This prediction model provided a strong basis for field inspection.

Abstract :
To quickly evaluate the material properties of ancient wooden structure members on site, the larch species of northeastern China was used as the research object, and the nondestructive testing method of the stress wave and the micro-drill resistance meter were used to measure it. The variation laws of the larch wood's cross and longitudinal property indexes were determined. According to the variation law of material property indexes, the detection divisions under the nondestructive testing technology of stress wave and micro-drill resistance instruments were divided, which provides a basis for improving the accuracy of on-site nondestructive testing. From the comparison of shade and light side data, it was found that there was little difference in material properties indexes. According to the change trend of larch wood with density, the pith, juvenile wood, mature wood, and overmature wood were divided, which provided a reference value for the study of wood growth laws.
