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.

The paper presents the preliminary planning of a demonstration pilot for exemplary renovation of an existing building (“Solar House 1 – Campina”) towards nZEB level using Passive House principles and technologies. The “Solar House” was one of the lighthouses of solar energy developments in the ‘80s in Romania, being built in 1977-1978 in Campina (Centre-South Romania) and represented an experimental building using innovative solar technologies for DHW preparation, active and passive space heating. The decision of transforming the existing building in a demonstration pilot nZEB with green materials was taken and the feasibility study is currently underway. The pilot aims to analyse and test, the cost effectiveness of Passive House (PH) technologies integration in a deep renovation process with the view to achieve the fixed nZEB levels, as an exemplary case study demonstrating the benefits and feasibility of applying PH principles and energy performance evaluation in real context. Both approaches of applying the renovation standard EnerPHit and targeting Passive House criteria are discussed together with the nZEB targets, while the analysis of technical (energy performance) and economic (total costs) feasibility is presented. The proposed building will act as a training and consultancy centre in Campina - created as a model for achieving greater energy efficiency and environmental responsibility in Romania.

This paper illustrates the results of comparative study regarding two RES storage solutions for a energen hybrid system that power supply a passive house. In this case-study was used sun and wind as a primary sources and their storage was realized in S1 scenario through electrolytic hydrogen and in S2 scenario through battery. The aim of this research was to demonstrate the capability of hydrogen to integrate renewable energy sources in green electricity production for stationary applications, especially to new concepts of low energy buildings. As main results was found that on S1 is harnessed 77% of total energy production of the system to obtain hydrogen and on S2 just 10%. Storage by electrolytic hydrogen generates 55% reduced amounts of CO2 emissions compared with storage by battery. Total S1 NPC was with 45,6 % higher than S2 due to conversion equipment of hydrogen into electricity.
