“…Apart from GBRTs, Passive House Planning Package (PHPP), whose calculation methodology focuses on fabric and ventilation losses, passive internal heat gain and solar gain, energy efficient plant and low carbon technologies, is a popular passive building design tool developed by the Passivhaus Institute and widely used in European countries. Its modeling accuracy is also validated by measurements conducted on Passivhaus projects [12,13].…”

“…However, in South Europe higher summer temperatures and solar radiation result for most building typologies and designs in an equilibrium of heating and cooling energy needs, the necessity to solve potential conflicts between winter and summer comfort objectives, a higher probability of having to install both heating and cooling systems (active or passive or hybrid) and to bear the associated costs. The study of Badescu [12] suggests that an active cooling and heating system should be used when pH buildings are implemented in the mixed mode and hot climates.…”

“…The over focus on energy performance in nZEBs can lead to health and comfort problems. Badescu et al reported excessive overheating hours in a Romanian case study and recommended the inclusion of active cooling systems for such high performance buildings [12]. However, the existence of various definitions of overheating and explicit indexes, including the long-term comfort indexes proposed in EN15251, are rarely used for designing buildings or assessing their actual comfort performance after occupation [30].…”

a b s t r a c tIn times of great transition of the European construction sector to energy efficient and nearly zero energy buildings (nZEB), a market observation containing qualitative and quantitative indications should help to fill out some of the current gaps concerning the EU 2020 carbon targets. Next to the economic challenges, there are equally important factors that hinder renovating the existing residential building stock and adding newly constructed high performance buildings. Under these circumstances this paper summarises the findings of a cross-comparative study of the societal and technical barriers of nZEB implementation in 7 Southern European countries. The study analyses the present situation and provides an overview on future prospects for nZEB in Southern Europe. The result presents an overview of challenges and provides recommendations based on available empirical evidence to further lower those barriers in the European construction sector. The paper finds that the most Southern European countries are poorly prepared for nZEB implementation and especially to the challenge/opportunity of retrofitting existing buildings. Creating a common approach to further develop nZEB targets, concepts and definitions in synergy with the climatic, societal and technical state of progress in Southern Europe is essential. The paper provides recommendations for actions to shift the identified gaps into opportunities for future development of climate adaptive high performance buildings.

“…Energy efficiency of the buildings is regulated by the European Union. All new public buildings in Poland must be nearly zero energy buildings by 31st of December 2018 and others by 31st December 2020 [3,5]. In accordance with Polish regulations non-renewable primary energy ratio in new public buildings presently should be lower than 60 kWh/(m 2. a) and after 2020 year should decrease to 45 kWh/(m 2. a) [7].…”

In the building designing process special attention should be paid to energy calculations - with analysis of different input data low energy or passive house can be obtained and decision of which parameters can or cannot be changed may be made. The following input data was analysed: shape factor A/V, glazed area, internal heat gains, air tightness, efficiency of heat recovery. The results show that the input data for the energy calculations are crucial for the obtained result.
