With the continuous promotion of the concept of sustainable development and the constant development of cities, the preservation and renovation of historical buildings have gradually become one of the important issues in urban development. This article introduces the value, importance, sustainable concepts in historical buildings, application of green building technologies in historical building preservation, as well as a compilation of representative cases from both domestic and international perspectives. Based on this, personal viewpoints are proposed for future practices in historical building preservation and renovation, along with an analysis and summary of the trends in historical building development.

This paper proposes an innovative design education model that effectively combines learning science theory, new technology, and new media to address the problems of serious homogenisation and disconnection from social requirements in design education. The model is based on the Chinese context, in accordance with the three principles of innovative design education summarized in Tim Brown’s design thinking, and utilizing the learning science theory, new technology, and new media. Analyzing the relationship between learning science theory, new technology, and new media, providing a reference for the full application of new technology and new media in Chinese modern design education, and promoting the application of learning science theory in Chinese modern design education constitute the construction of the model.

In this paper we researched the vehicle braking sense in three aspects of human, vehicle and environment and analysed their impacts on brake feeling. Through the real vehicle test we analysed the relationship among pedal force, pedal travel and deceleration. We used dynamometer test method to study the brake noise question. We designed a fixture which could imitate the suspension and made the test more close to the true level. Moreover we discussed how to establish the evaluation system of vehicle braking condition. Through real vehicle test of braking, we can test and record the brake system parameters in the braking process under urban working conditions. We recorded the brake frequency, the change of brake speed and brake disc temperature. Meanwhile, based on the analysis of braking condition, we put forward the index of brake load to reflect the city’s traffic conditions. Experiment show that the braking condition and brake feel are related, braking condition also provides theoretical support for the design of brake system.
