The work presents the kinematic and dynamic control of a mobile robotic manipulator system based on numerical methods. The proposal also presents the curvature analysis of a path not parameterized in time, for the optimization of energy consumption. The energy optimization considers two aspects: the velocity of execution in curves and the amount of movements generated by the robotic system. When a curve occurs on the predefined path, the execution velocity is analyzed throughout the system in a unified method to prevent skid effects from affecting the mobile manipulator, while the number of movements is limited by the redundancy presented by the robotic system to optimize energy use. The experimental results are shown to validate the mechanical and electronic construction of the system, the proposed controllers, and the saving of energy consumption.

Removal System

The consumption of copy or print paper has been rapidly increasing. There are several aspects to be considered for environmental conservation, for example, resource of woods, energy consumption and paper trash in office, etc. We have been developing the toner removal system from copied paper since 1993. We have improved such as machine service life, toner removal mechanism, toner removal quality, special paper and running cost, etc. We have developed a commercial prototype. The system proved that a toner removal system permits reuse of a copied paper multiple times so that the system is effective for environment conservation.

Consumption Prediction

Accurate prediction of buildings’ lifecycle energy consumption is a critical part in lifecycle assessment of residential buildings. Longitudinal variations in building conditions, weather conditions and building's service life can cause significant deviation of the prediction from the real lifecycle energy consumption. The objective is to improve the accuracy of lifecycle energy consumption prediction by properly modelling the longitudinal variations in residential energy consumption model using Markov chain based stochastic approach. A stochastic Markov model considering longitudinal uncertainties in building condition, degree days, and service life is developed: 1) Building's service life is estimated through Markov deterioration curve derived from actual building condition data; 2) Neural Network is used to project periodic energy consumption distribution for each joint energy state of building condition and temperature state; 3) Lifecycle energy consumption is aggregated based on Markov process and the state probability. A case study on predicting lifecycle energy consumption of a residential building is presented using the proposed model and the result is compared to that of a traditional deterministic model and three years’ measured annual energy consumptions. It shows that the former model generates much narrower distribution than the latter model when compared to the measured data, which indicates improved result.

Technical Measures

The paper focuses on analysis and assessment of economic effectivity of measures taken in order to lower energy demands of prefabricated panel residential buildings. For this purpose, a group of buildings with previously made modifications with potential to lower the energy and heating consumption were selected. Next, the development of their energy consumption and their costs was monitored. The assessment of achieved figures was made with regards to amount of costs which were paid for these measures and also with regards to their service life, amount of gained subsidy and decrease of consumed energies and operational costs of the buildings after the measures were taken. It was found that there had been a significant difference in investment returns for constituent technical measures. For some of them, it is not even realistic to expect reaching the return of investments during their service life period.

The paper discusses the use of the combined control for a system of two parallel pumps to increase its service life. Using the combined control, the pumping system is controlled together by change the speed, throttling, and bypass. The power consumption of the pumping system is calculated for three methods of flow control: with minimum energy consumption, with maximum reliability, and control with a trade-off between efficiency and reliability. In the case of control with maximum reliability, the energy consumption of the pumping system is higher than in the case of control with minimum energy consumption by 29.2%. In the case of the proposed trade-off control, which provides acceptable reliability, the power consumption is higher than with the minimum energy consumption control by only 7.3%.

The aim for this research is to identify the issues with poor thermostat designs in a window-wall condominium suite during cooling season, and to investigate how low-cost changes in the design can improve occupant comfort, reduce energy consumption, and increase terminal equipment service life. Temperature logging and fan coil operation monitoring procedures were carried out during the peak cooling season in a sample condominium suite located in Toronto, Ontario. Data was collected and analyzed presenting the effects of thermostat installation in proximity of an exterior window-wall and supply air diffuser, and system durability concerns of implementing a proportional-based algorithm via pulse width modulation. Several design changes have been proposed that can be implemented at negligible cost during construction design and are expected to lead to comfort and system improvements during the cooling season.
