The Calculation of the Seasonal Performance Factor (SPF) of a Domestic Hot Water Heat Pump Integrated with a Mechanical Ventilation Installation with Heat Recovery for a Residential Premises in the EnerPHit Standard

Abstract

This paper presents the results of a survey on the state of public awareness of nature-based technologies in construction and, in particular, opinions on green roof and green wall technologies in Poland. The survey was conducted in December 2023, online, using thematic groups on a social networking site. The groups focus on urban ecology and green solutions in construction. A total of 210 people participated in the survey. Its results showed that although green technologies are gaining interest, the percentage of respondents who either live or have lived in buildings that feature these solutions remains small. The respondents displayed a positive attitude towards green roofs and walls, and considered them an interesting and safe solution. The positive perception of these technologies stems from, among other things, their potential impact on air purification, smog reduction and increased oxygen production. The respondents recognized and valued the aesthetic qualities of green technologies, appreciated their impact on improving the appearance of cities and the creation of additional places for relaxation, which are increasingly sought after in urban space. One can see the need to further promote and educate the public about the benefits of green technologies in construction. Their sustainable development can not only positively affect the aesthetics of cities, but also contribute to the creation of greener and more people-friendly urban spaces, in line with the needs of modern society.
