The modern agriculture model is a model based on the principles of sustainable development, i.e. protecting the environment and the cultural landscape on the one hand, and on the other, ensuring adequate income for residents. It is based on three orders: ecological, social and economic. This paper attempts to use cluster analysis to assess the economic and ecological sustainability of organic farms. It also indicates the factors that statistically influenced the assessment of a farm as sustainable, or not. The first part of the work is dedicated to the characteristics of the problem and the methodology of research and analysis. The second part contains the results of the research and discusses them.

The size of all sensible heat balance components in livestock building varies in time, because it depends on time-varying weather factors. On the example of two buildings, sensible heat balance was shown on a daily basis. Measurements carried out in winter and spring in two livestock buildings with usable attics included measurements of air temperature and humidity inside and outside, air velocity in ventilation channels, and wind speed. Measuring devices were designed to record the results of measurements at intervals of 300s. During each such time interval, sensible heat losses by ventilation, heat losses by permeation through the barrier construction, and the amount of sensible heat produced by the animals were calculated. The results of measurements were shown in graphs. The study is important for the development of animal livestock building.
Development investment capacity of farms depends on their potential and scale of production, and thus its revenue, which determines the scale of investment purchases. Most specialized farms have growth potential. Farmers take great interest in modernization and investing in new technologies, machinery and agricultural land, as confirmed by market analysis. Literature references offer information regarding the needs and investment opportunities of territorially diversified farms running conventional production, however the aim of the work is to determine the investment possibilities of organic farms with various production branches. The research included 50 farms certified as ecological producers. In order to answer the question which type of business has the greatest development potential, the examined facilities were divided into branch groups.
