The scope of this paper is focused on health and wellbeing of the occupants. The building completed in the year 2009 is planned for an in-depth POE to start this yearthe first such broad evaluation project to be carried out in Poland. Measurements taken already and the feedback from the occupants received so far indicate whether certain design intentions have been met. Selected usability problems that have already occurred are discussed as well as the way the occupants cope with them. Selected details that proved to be successful are also presented. An overview of the process of the building delivery, handover and maintenance is also presented as in the authors opinion it has a major impact on the building's overall performance. The paper concludes that most usability problems are lessons to be learned indicating improvements that can be made in a building's life early stages.

Due to more stable temperatures, these unconditioned areas around the building reduce heat losses during the heating season and present better overheating protection in the summer. In this concept the exterior skin protects building from the weather conditions and the interior skin gives thermal insulation. This paper presents the concept and the simulation results run in order to determine its influence on building energy demand.

These systems occupy a large area in relation to a building's floor surface, especially when they are located in a climate like Central Europe or colder. The aim of the article was to create a balanced integration process by implementing the subsequent steps that are necessary to integrate a solar heating system within a building. In the first stage, a solar collector and a heat accumulator were selected. The innovation of the system involves the use of a solar concentrating collector as an air heater. Assessment criteria were then proposed in order to show the influence of the location of the solar heating system on the building's architecture, functionality, and energy balance, while at the same time assuming its passive standard. System integrations concerning both an existing and new building were analyzed. The system's basic components were selected for the three chosen solutions, taking into account the possibility of using heat losses resulting from the location of the installation.

Described is the process of the building's delivery and a preliminary evaluation of selected design solutions. The building, completed in the year 2009, is planned for an in-depth POE to start this yearthe first such broad evaluation project to be carried out in Poland. An in depth knowledge of the design and construction process, measurements taken already, feedback from the occupants, and tracks of all faults reported so far, allow a preliminary evaluation of the building's environmental performance. A comparison of total energy consumption and CO2 emissions between the analyzed building and two other selected schools from Wroclaw is included. It is based on energy bills for all fuel sources used. It indicates energy efficiency of the building and relatively high CO2 emissions due to its sole dependence on electricity.

The survey was conducted among 118 architects involved in the preparation of project documentation required by Polish law for newly built facilities. The article presents the background and methodology of the conducted research, including the design process and selected architectural and construction procedures conditioning the real improvement of the energy efficiency of the Polish construction industry. The results of surveys regarding architects’ opinions on the practical application of energy performance as the basic tool for energy evaluation and their approach to the issues of efficient energy management in buildings were presented. These results were confronted with the current architectural and construction procedures in Poland. The conclusions were drawn up and the weaknesses of the latest regulations and routines were presented. The recommendations for their improvement were formulated, showing the urgent necessity of preparing and educating architects in order to effectively implement the EU climate and energy policy. The results of the research were presented during expert meetings at the Ministry of Investment and Economic Development (MIED) in November and December 2018, aimed at improving the legal regulations related to the implementation of the new Directive 2018/844/EU into the national law.
