- Abstract
- The energy performance certificate is a widely known, important means of comparing the energy efficiency of buildings.
In any case, the integration of greenery into the energy performance certificate can be seen as a target-oriented means to push the implementation of greenery in buildings and to sensitize relevant actors to the topic.
The aim is, on the one hand, to adapt the calculation models in the energy performance certificate so that greenery in buildings can be depicted as realistically as possible and, on the other hand, to assess the acceptance of implementation by the relevant stakeholders.
At present, it would be possible to map the effect of the greening of buildings on the U-value in the energy certificate. Changes in the U-value result in a change in the heating demand and other parameters.
In the future, the effect of green buildings on summer overheating could also be mapped. The influence of greenery on the microclimate could be estimated by means of simulations and measurements and subsequently be incorporated into the energy performance certificate by means of changes to the site climate. It is also conceivable, for example, to record the influence of building greenery on solar systems.
Workshops with the involvement of relevant stakeholders could be used to obtain an initial assessment of the acceptance and feasibility of such changes in the energy certificate.
The applicant is deputy chairman of the Austrian standardisation institute Committees ON-K 175 (thermal insulation of buildings and building components), ON-K 141 (air conditioning and ventilation technology) and ON-AG 235 (economical use of energy). There, the calculation methods, regulations and technology of energy-efficient construction are further developed. For this reason, the applicant has many years of experience in co-designing the standards that provide the calculation basis for the energy performance certificate.
This ensures that the approaches of the study can not only be realistically implemented, but also discussed with the relevant actors and key players in the standardization committees.
