Performance gap concerns limit investment in the building energy efficiency retrofit market. In particular, the ability of projects to deliver on promised energy savings is commonly drawn into question. Performance risk mitigation mainly occurs through energy saving performance guarantees. Contractual stipulations arrange the conditions of the guarantee, and ceteris paribus, a higher energy saving guarantee should reduce project performance risk. Therefore, methods that yield a higher energy saving guarantee could help accelerate the market. We review the ability of “smart,” automated, and connected technologies to: (a) intelligently monitor and control the performance of energy-consuming devices to reduce performance variations, (b) provide additional degrees of control over the project’s performance, and, by doing so, (c) motivate the energy services company (ESCO) to raise the energy saving guarantee. Our analysis finds that use of such automated performance control could significantly raise the energy saving guarantee, making projects more likely to succeed.

The energy efficiency requirements of most energy-consuming sectors have increased recently in response to climate change. For buildings, this means targeting both facility managers and building users with the aim of identifying potential energy savings and encouraging more energy-responsible behaviors. The Information and Communication Technology (ICT) platform developed in Horizon 2020 FEEdBACk project intends to fulfill these goals by enabling the optimization of energy consumption, generation, and storage and control of flexible devices without compromising comfort levels and indoor air quality parameters. This work aims to demonstrate the real-world implementation and functionality of the ICT platform composed of Load Disaggregation, Net Load Forecast, Occupancy Forecast, Automation Manager, and Behavior Predictor applications. Particularly, the results obtained by individual applications during the test phase are presented alongside the specific metrics used to evaluate their performance.

Testing Work

With the deepening of the energy conservation of the building, energy saving from the original design of building energy-saving gradually turned to the field detection and completion acceptance, which requires a corresponding energy-efficient means of detection. With the development of infrared technology, the combination of infrared technology and detection methods of building energy-saving, to further promote the development of building energy efficiency testing work. Compared to the traditional heat flow meter or hot-box method, infrared thermal imaging method has no effect on the measured object, detecting the surface temperature of quick reaction speed, accompanying with wide temperature range and high precision, is widely used in various fields of testing work, which has been particularly prominent in the thermal defect detection. In this paper, the method of infrared thermography is used to confirm whether the thermal defects exist in energy-saving construction or not. Testing results show that infrared thermography can accurately reflect the temperature distribution of building wall surface. Infrared thermal imaging to detect the building surface's energy efficiency, which is providing efficient and accurate means of detection for the evaluation of the building energy efficiency. This is to help carry out a comprehensive building energy-saving testing.

The Government

The constraints of resources and environment in China are more and more intense. The 12th Five-Year Plan requires that energy saving must be considered in the architectural design. Liangshan has special climate and sunshine. Therefore, the Government of Liangshan requires that building energy saving must be started from the stage of architectural design. Building energy efficiency must be considered from several aspects, such as architectural layout, wall structure, windows and doors, roof structure, external sun-shading, and construction materials.

China is a big industrial energy consuming country. The largest proportion of energy consuming is the operations of separation in chemical industry, and the energy consumption of the distillation is the highest in separation. Therefore, it is very important to research energy-saving issues of the process of distillation in today's circumstances of the energy shortage. This article describes the model of heat pump distillation column,and its characteristics, uses static simulation programs to simulate operating conditions in the atmospheric pressure for the benzene-toluene material system, and studys effects of the different feed states on the energy-saving of heat pump distillation column. The results will be compared with the conventional distillation column, and it was showed that for benzene-toluene system, the heat pump distillation column is more remarkable than the conventional distillation column in energy savings, and its energy saving rate can reach 46%.

This paper studies an interdisciplinary approach for improving smart energy systems, and, in particular, building energy efficiency. Currently, energy audit is the most widely used approach to improve building energy efficiency. Energy audit increases the building energy efficiency by identifying, analyzing and implementing energy saving opportunities in existing buildings. The procedure of existing energy audit approach is relatively standardized, and energy audit professionals usually refer to Energy Conservation Measures (ECMs) checklists to determine opportunities for energy savings. In this context, this paper aims to improve the general energy audit process by integrating, adapting, and extending Design Innovation (DI) techniques which help to identify more energy saving opportunities beyond the existing energy audit checklists and deliver user-centered and disruptive innovative energy-saving solutions which are missing in the traditional energy audit procedure. The motivation, advantages, and the implementation procedure of selected DI approaches are explained separately. To demonstrate the effectiveness of the proposed mechanism, an example of developing a smart energy system for a building testbed is given.
