City highway tunnel ventilation design is one of the key processes in whole tunnel design. The ventilation design has important influence in ventilation sanitation effect, equipment investment, operations energy consumption and operations cost. On the premise of safety and sanitation, if city tunnel adopts natural ventilation, this can reduce energy consumption, construction cost and operations cost. Combining practical conditions of a project, this paper evaluated three kinds of mechanical ventilation, and analyzed contrastively economic efficiency of the natural ventilation and the jet longitudinal ventilation. At last drew the conclusion that the natural ventilation can reduce the total investment by 30% and has obvious energy-saving efficiency, then put forward the pertinent suggestions to the ventilation construction of highway tunnel.

In recent years, with the rapid increase of tunnel percentage in Midwestern highway construction, the tunnel operation cost rise quickly. In the cost, energy consumption of tunnel ventilation and illumination occupies a great proportion. In order to realize energy-saving and emission-reduction, there have been some new ventilation technology, for instance, the improved ventilation device, the improved ventilation method, and some new ventilation control technology. However after some new technology was applied, the phenomenon of energy-saving but not money-saving appeared. For the scientific and objective evaluation of highway tunnel ventilation technology energy-saving effect, construct evaluation index system from the three dimensions of technology usability, economy, and application effect, and then evaluate the energy-saving effect based on matter-element model. The result of assessment will give decision support for the later selection of highway tunnel ventilation technology proposal.

As the major public buildings and cultural service institutions, libraries play an important role in the strategy of energy-saving buildings. In order to keep pace with the footstep of Western developed countries, China has launched a series of green and energy-saving building practices and achieved certain results. The New Hubei Library is a successful example, with Chinese national conditions and the characteristic of the library itself taken into consideration, and limited conditions in the design process fully made the most use of. Besides the designer has efficiently used energy-saving strategy on building structure maintenance, solar radiation, air conditioning control system and natural ventilation, finally achieved the goal of energy saving of library.
