With the development of urbanization, the building energy conservation has been paid more and more attention, and 50% to 60% of the power energy consumption—the energy consumption of air-conditioning be paid attention for people. Research about measuring and analysis on energy consumption of VAV air-conditioning system is described in this paper. A measuring and analysis solution has been implemented in the VAV Air-Conditioning laboratory of Xi’an University of Architecture & Technology (XAUAT). The satisfactory results are given.

For ocean-going vessels sailing in different areas on the sea, the change of external environment factors will cause frequent changes in load, traditional ship air-conditioning system is usually designed with a fixed cooling capacity, this design method causes serious waste of resources. A new type of sea-based air conditioning system is proposed in this paper, which uses the sea-based source heat pump system, combined with variable air volume, variable water technology. The multifunctional cabins’ dynamic loads for a ship navigating in a typical Eurasian route were calculated based on Simulink. The model can predict changes in full voyage load. Based on the simulation model, the effects of variable air volume and variable water volume on the energy consumption of the air-conditioning system are analyzed. The results show that: When the VAV is coupled with the VWV, the energy saving rate is 23.2%. Therefore, the application of variable air volume and variable water technology to marine air conditioning systems can achieve economical and energy saving advantages.

Using the energy consumption simulation software to research the HVAC in fall air conditioning mode, different building orientation and window-wall ratio of the office building energy consumption. The study found that the heating energy consumption, air-conditioning energy consumption and total energy consumption is gradually increased with the increase of the window-wall ratio under the same orientation. The result provides some reference for public buildings in setting of building orientation and window-wall ratio.

Variable Air Volume (VAV) air-conditioning system presents great energy savings potential especially in hot and humid climate and has been recommended in the Building Energy Code of Taiwan since 1996. Simulation results indicated that the annual energy savings of VAV system in typical commercial buildings in Taiwan could be up to 70% of total fan power. A full-scale experiment has been performed which validated this result successfully, and would be adapted with the PACS index in the second phase of national Building Energy Code in Taiwan.

In this paper, with the aid of energy consumption simulation software DeST-h, the annual air conditioning energy consumption of a typical residential building in Guangzhou was simulated to study the impact of window-wall ratio on the energy consumption under two different operation modes: natural and mechanical. It was revealed that increasing of south window-wall ratio, building energy consumption is increased under all mechanical mode, but reduces under nature priority mode.

The building energy consumption simulation software DeST is used to analyze the effects of fixed shading over external window on energy consumption and efficiency, on the base of a residential building in Shanghai. The simulation results show that the fixed shading over south window has little effect on the overall energy saving of residential building. For east and west external window, if window area is not very large and its shading performance is better, the effect of fixed shading installation on energy saving is not obvious. On the contrary, if its area is large and its shading performance is ordinary, the effect is remarkable. Furthermore, when room ventilation capacity is poor, the effect of energy saving by fixed shading installation is more prominent.

This paper presents a comparison of concept stage computational model predictions to capture how building energy consumption is affected by different climate zones. The California State University, Fullerton (CSUF) Student Housing Phase III, which received a Platinum Leadership in Energy and Environmental Design (LEED) certification for the Building Design and Construction category, and its performance in a LEED California Nonresidential Title 24 (NRT24) and ASHRAE 90.1 climate zones is used as a case study to illustrate the method. Through LEED approved simulation software, the standard compliant energy simulation models are compared to the occupancy scheduled models along with the actual energy consumption in different climate zones. The results provide insight to how variables within student dormitory life affect total building energy usage. Total amount of energy consumed per area is one new factor providing understanding into occupancy trends. This new data set reveals more understanding regarding how and where the energy is consumed to maintain a comfortable learning environment.
