BIMcert achieved two kinds of impacts:
1) Building capacities and skills of construction sector professionals of various profiles,
2) Inducing potential in construction sector professionals to achieve improved energy performance of builidngs, as well as to increase share of low carbon and renewable energy sources in energy supply of buildings, by implementing BIM tools in their workplaces.
1) Building capacities and skills
The project has achieved the following impact through communication, dissemination & training activities:
• Project Website page visits: 18,999
• Platform user visits: 39,576
• WP2 Industry Engagement Survey & Workshop: 619
• *WP6 Trials participation: 422
• Presentations to 82,362 attendees at International Conferences & Workshops
• Total registered users on BIMcert Platform: 390
• Registered users on website, for access to newsletters & training materials: 1,586
• 231,317 total impressions on Twitter
2) Energy savings and RES generation
2.1) Energy savings
As demonstrated in the case studies of sample projects, energy savings that can be achieved by application of BIM, when compared to traditional method, are equal to:
- 29 kWh/m2/year for a new project
- 33 kWh/m2/year for a renovated building.
2.2) RES generation:
33 kWh/m2 per year * 2100 m2 *2 projects* 310 participants *0,8*0,65* 0,15 =3,351 GWh/year
A reduction coefficient of 0,15 is applied, presuming that, unlikely the energy savings described in the sub-chapter, BIM skills might not be the only factor enabling the increased RES share expected from the construction/ renovation projects, i.e. some RES implementation could be made by traditional methods as well. The contribution of BIM skills is assessed to be 15%, mostly due to: 1) the simulation of the building optimal orientation in space, providing optimal use of solar energy for electricity and heat generation, and 2) faster and more accurate analysis of a large number of design alternatives, wherein a large number of factors influencing the building energy performance, including varying share of renewable energy supply, can be varied, analyzed and optimized.
Summary:
The capacity of all stakeholders included in the project activities, for implementation of digital skills for improvement of energy performance of buildings has been increased and will lead to improved energy performance when applied in their workplaces. The project has therefore achieved the following impacts in terms of increased share of clean and efficient energy in buildings:
• Primary energy savings triggered by the project within its duration: 32,498 GWh/ year
• Renewable energy production triggered by the project within its duration: 3,351 GWh/year
