Supporting designers in the early stages of designing Plus Energy Buildings is strategic to ensure load reduction while still considering the household practices and enhancing the indoor environmental quality. To achieve this target, it is necessary to make use of effective building energy modeling with a clear view of the simulation results, thus allowing effective communication between the design team and the involved disciplines/stakeholders.
The Cultural-e survey is aimed to identify principal decision-making issues and performance indicators that are meaningful to designers and stakeholders. The result will be analyzed by automated data visualization charts and generate reports.
The survey has been concluded with 101 participants, of which 59 replies have been considered valid including only professionals from the fields of architectural design, environmental design and building physics in the residential sector.
The first part of the survey introduces the participants highlighting their field of work, their level of experience and their preferred energy performance targets. As the survey progresses, it investigates the principal aspects they want to evaluate through the building performance simulation and therefore the performance indicators that they might need.
Who participated in the survey?
Most of the participants have a high level of experience and have worked on more than 10 projects in the residential building sector.
Based on their experience, the most common energy performance target set in the building design is Nearly Zero Energy Building (25%), followed by Low energy building (19%), Passivhaus (15%), Net Zero Energy Building and Plus Energy Building (6%). It is also interesting that at least one participant per country prefers their own National Building Regulation as target to evaluate the performance of the building.
Among the most used energy certifications in the European panorama, 54% of participants prefer national certifications, 28% international ones, while 18% do not use any certification probably because it is not always required by their clients.
