Development of renewable energy, based on biomass energy, requires a wide range of studies aimed at developing effective agroecotechnology for a wide range of energy crops that can be grown in the country. The aim of this article is to present the most important directions of research in the field of improvement of agroecotechnology biomass production which will be based on energy plant species collected in the RES Technology Transfer Centre in Konstantynow Lodzki (Poland).

The objective of the paper is to describe the requirements of passive house standard based on an example of RES TTC building. The requirements were divided into main prerequisites for energy demand and specific recommendations for particular factors. The calculations and analysis have shown that in order to achieve the required energy demand, it is necessary to apply better solutions than recommended, e.g. ventilation units with higher efficiency of heat recovery. The same refers to U-values of the building elements. The use of ventilation units with recommended efficiency of 75% does not guarantee achieving of the passive standard.

The article presents the basic assumptions of qualitative methodology, which is gaining popularity among researchers in social sciences. There is the noticeable return from constructing theory \"behind the desk\" to the conducting field researches. There is also increasing importance of new research methods, like the autoethnography.
