Description of the research topic:
a.) Antecedents:
As a result of environmental challenges and related EU priorities, energy efficiency has become one of the
most important aspects of building design, where the main goal is to reduce the non-renewable energy
consumption of the building sector. Thanks to the controlled environment, the process of tightening
building energy requirements is accelerating. This also includes the need of utilizing renewable energy
sources along with introducing smart solutions such as smart homes and smart grids. It is important to
note, that compared to the existing building stock the ratio of new buildings is just a small fraction, thus
the possibilities for reducing the non-renewable energy consumption of existing buildings is of utmost
importance with the possible integration of renewable energy sources and smart solutions.
The use of simulation tools in building design and building energy performance certification is becoming
standard practice. The impact of occupant behavior on the operational energy use of buildings and the
building efficiency is potentially very large but it is not well represented in simulation models. Also the
complex modeling of both the demand and the production side has to be more deeply ínvestigated.
b.) Aim of research:
1. Complex analysis of PV production and buildings' electricity consumption based on smart meter data.
2. Simulation of building energy consumption and PV generation for different building types, including
real life case studies.
3. Evaluating demand side management options including potential in influencing electric car charging
habits (based on measured consumption of e-charging stations).
4. Development of user profiles for building simulation software, energy audits and certifications for
different building types and functions.
c.) Tasks, main items, necessary time:
1" year, tasks:
- Literature review: conditions and limitations of developing electricity consumption and generation
profiles, grid interactions; application boundaries of building simulation software.
- Collection of meteorological data (solar radiation, air temperature etc.) for assessing the measured
consumption and measurement data for the proposed simulations.
- Collection of electricity consumption data from smart meters measuring building energy consumption,
PV production and e-charging points of electric cars, data filtering and sorting.
- Preliminary building simulation runs to evaluate the program, finding limitations to the applicability in
Hungary. Identification of input data needs, structure and format.
2nd year, tasks:
- Development of consumption patterns for different usage profiles, including different building functions
and e-charging points for electric cars.
- Identification and development of hourly and daily PV production and electricity consumption profiles.
- Comprehensive assessment of PV production and electricity consumption profiles.
3' year, tasks:
- Summarizing and assessing the results of the first 2 years.
- Performing building energy simulations for the selected buildings to evaluate the proposed consumption
and production profiles.
- Parameter analysis for the created simulation models to assess the sensitivity for the different input
parameters.
4t hy ear, tasks:
- Summarizing the results and experiences of simulations carried out based on consumption data.
Proposal of a simulation process for the Hungarian conditions.
- Development of building user profiles for further simulation processes, energy audits and certifications
for different building types and functions.
- Developing new scientific results in the form of a thesis.
d.) Required equipment:
For the research the necessary equipment are present at the department, which includes dynamic
simulation programs (DesignBuilder and TRNSYS). Also for the resource demanding simulations an
appropriate PC is available at the Department. Data required for the research is available from
previous and ongoing projects as well.
e.) Expected scientific results:

real life case studies.
3. Evaluating measured electric car charging habits based on measured consumption of e-charging
stations.
4. Development of user profiles for building simulation software, energy audits and certifications for
different building types and functions.
