Abstract Advanced building climate control systems have the potential to significantly reduce greenhouse gas emissions and energy costs, but more research is needed to bring these systems to market. A key component of building control research is testing algorithms through simulation. Many high-fidelity simulation testbeds exist, but they tend to be complex and opaque to users. Simpler, more transparent testbeds also exist, but they tend to neglect important nonlinearities and disturbances encountered in practice. In this paper, we develop a simulation testbed that is computationally efficient, transparent and high fidelity. We validate the testbed empirically, then demonstrate its use through the examples of system identification, online state and parameter estimation, and model predictive control (MPC). The testbed is intended to enable rapid, reliable analysis of building control algorithms, thereby accelerating progress toward reducing greenhouse gas emissions at scale. We call the resulting testbed and supporting functions the bldg toolbox, which is free, open source, and available online.

Scenario Approach

On the eve of the worldwide negotiations of a new climate agreement in December 2009 in Copenhagen it is important to clearly understand what Russia can do to mitigate energy-related greenhouse gas emissions in the medium (until 2020) and in the long term (until 2050). The paper investigates this issue using modeling tools and scenario approach. It concludes that transition to the "Low-Carbon Russia" scenarios must be accomplished in 2020—2030 or sooner, not only to mitigate emissions, but to block potential energy shortages and its costliness which can hinder economic growth.

Global Problems

Aim. Proper development of animal breeding in the conditions of current global problems and the decrease of anthropogenic burden on environment due to greenhouse gas emissions, caused by animal breeding activity, require the study of interaction processes between animal breeding and external climatic conditions. Methods. The theoretical substantiation of the problem was performed based on scientifi c literature, statistical informa- tion of the UN Food and Agriculture Organization and the data of the National greenhouse gas emissions inventory in Ukraine. Theoretically possible emissions of greenhouse gases into atmosphere due to animal breeding in Ukraine and specifi c farms are calculated by the international methods using the statistical infor- mation about animal breeding in Ukraine and the economic-technological information of the activity of the investigated farms. Results. The interaction between the animal breeding production and weather-and-climate conditions of environment was analyzed. Possible vectors of activity for the industry, which promote global warming and negative processes, related to it, were determined. The main factors, affecting the formation of greenhouse gases from the activity of enterprises, aimed at animal breeding production, were characterized. Literature data, statistical data and calculations were used to analyze the role of animal breeding in the green- house gas emissions in global and national framework as well as at the level of specifi c farms with the consid- eration of individual specifi cities of these farms. Conclusions. Current global problems require clear balance between constant development of sustainable animal breeding and the decrease of the carbon footprint due to the activity of animal breeding.
