Energy saving always attracts many countries'attentions. Energy saving reform of the existing buildings was accepted in many countries. There are a lot of innovation in energy saving. In this paper, we believe that TRIZ can solve these problems in energy saving. Then, we constructed a model of energy-saving based on TRIZ. This model proposed preliminary solutions by using TRIZ in energy saving. TRIZ will be applied more in this field.

with the vigorous development of construction in our country, the proportion of the building energy consumption in total is increasing step by step, especially the 1980s existing buildings, the vast majority of them failing to take any insulation measures, the energy consumption of them is several times or even ten times to new buildings, therefore, in recent years, energy saving reconstructions of existing buildings have paid more and more attention. This paper takes a typical office building which was built in sunan region as an example, using some external thermal insulation materials such as rigid polyurethane foam plastics, polyurethane composite board and energy saving design software BECS to imitate energy saving reconstruction. Besides, the economy of each scheme of energy saving reconstruction was also analyzed. The results show that, energy saving reconstruction can greatly reduce the energy consumption of existing buildings, and bring good economic benefits, at the same time, it also can improve indoor comfort and working conditions, and can generate significant social benefits.

Building Energy Saving

Existing buildings energy-saving renovation is an important means to cope with global warming and an essential component of achieving China’s energy conservation and pollution emissions reduction strategy goals. The development of the energy-saving renovation market is closely related to its influencing factors, which determine the reasons and conditions for the development of the system; therefore, it is necessary to study the influencing factors of energy-saving transformations. System dynamics was applied to explore the feedback relationship between the service subsystem, the demand market subsystem, and the market regulation subsystem. Analysis was performed for the intrinsic influencing factors of the development of the existing building energy-saving renovation market and the interaction law of feedback relationship. This paper discusses the basic characteristics of government incentives, Energy Service Company (ESCO) technology innovation, ESCO’s revenue, and owner’s awareness to promote the development of the existing building energy-saving renovation market. Base on those, it puts forward suggestions for promoting the market development of existing buildings energy-saving reconstruction. The findings provided a theoretical basis and guiding role for the Chinese government to formulate support policies for existing building energy-saving renovation. At the same time, it also provides reference for other countries to develop existing buildings energy-saving renovation market.

The energy-saving reconstruction for the existing building is very important for the large number of existing buildings in China. The energy-saving reconstruction in the roof is the key of the building energy-saving construction, and also the inevitable way for improving the urban heat island effect and comfort of the top-floor rooms. The energy-saving roof can be divided into two types including passive cooling and proactive cooling. This article analyzes the advantages and disadvantages of the two types before coming up with the ways and expectation for the energy-saving construction of the existing building roof.

In China, a surging urbanization highlights the significance of building energy conservation. However, most building energy-saving schemes are designed solely in compliance with prescriptive codes and lack consideration of the local situations, resulting in an unsatisfactory effect and a waste of funds. Moreover, the actual effect of the design has yet to be thoroughly verified through field tests. In this study, a method of modifying conventional building energy-saving design based on research into the local climate and residents’ living habits was proposed, and residential buildings in Panzhihua, China were selected for trial. Further, the modification scheme was implemented in an actual project with its effect verified by field tests. Research grasps the precise climate features of Panzhihua, which was previously not provided, and concludes that Panzhihua is a hot summer and warm winter zone. Accordingly, the original internal insulation was canceled, and the shading performance of the windows was strengthened instead. Test results suggest that the consequent change of SET* does not exceed 0.5 °C, whereas variations in the energy consumption depend on the room orientation. For rooms receiving less solar radiation, the average energy consumption increased by approximately 20%, whereas for rooms with a severe western exposure, the average energy consumption decreased by approximately 11%. On the other hand, the cost savings of removing the insulation layer are estimated at 177 million RMB (1 USD ≈ 6.5 RMB) per year. In conclusion, the research-based modification method proposed in this study can be an effective tool for improving building energy efficiency adapted to local conditions.

Lately Malaysia energy consumption versus generation rapidly shows increasing due to increasing of load. This phenomenon happened following to advanced country development. Lacking on design and without energy management approach the energy consumption and monthly electrical bill will steadily increased and support the increasing of world carbon emission. Therefore the aim of this work is to approach the simplest innovation task-energy audit , which is load-apportioning strategy. This approach using matching the usage of equipment with fully utilized space and reschedules the time of usage. A one week data was collected by logged power meter at main switchboard at selected building using Fluke Power Recorder. From the data collected, current usage of every load can be determine, then load will be arrange into a group with same portion and same time of usage. The result shows clearly the energy consumption for every single day and indicates the highest and lowest peak. From this work the apportioning strategy implemented by rearrange the load following type of room application. After the arrangement, new measurement was taken and a very good result was established. This work also can be further apply for a huge load that can be save a lot of money for owner especially government by energy saving.
