Besides the realised and monitored demonstration buildings,
the project has performed socio-economic research such as an overview report on financial
strategies in the different participating countries for the improvement of the energy quality
in the existing building stock. A detailed analysis of barriers for the energy efficient
retrofit of public buildings was also made. Both reports are available on the website together
with a communication guide for energy renovations.
The partners of BRITA in PuBs have also written 14 retrofit design guidelines with about 4-8
pages each, focusing on specific technologies like innovative insulation, advanced windows,
passive solar heating, reduction of overheating, hybrid ventilation, improved daylighting,
solar thermal systems, solar heating and cooling, photovoltaic integration and heat pumps or
on more general items. The latter deal with the interdisciplinary design approach, energy
simulation tools, life cycle assessment and long-term monitoring. The guidelines contain
information on why to use the technology, requirements in regulations, current practice,
different innovative solutions with their advantages and disadvantages, energy savings and
costs, as well as information on maintenance and best practice examples. They are available
for download at the project website.
An electronic database offers many different types of information for decision-makers on
public renovation projects. The BRITA in PuBs information tool BIT presents in an clearly
structured and simple to use way all demonstration buildings from the project plus additional
more than 30 educational case study buildings from a just finished IEA project. In a matrix the
buildings are opposed to different retrofit strategies starting with the building envelope, over
heating and ventilation systems, solar control and cooling systems, lighting systems to renewables
and management methods. The retrofit technologies and the case studies are described in detail
in so-called viewers. For both, the case studies and the retrofit measures, more detailed information
is offered as pdf-downloads including the final reports from the demonstration buildings and the
retrofit design guidelines. An additional feature of the information tool is the performance rating
tool. Here the user can visually compare the electricity, heating and water consumption of a specific
building with the national average for in total 19 different building types.
Another project result is the quality control toolbox. The energy efficiency of buildings
should be confirmed in all major stages of a renovation project: planning and design, implementation,
use, operating and maintenance. The energy and facility management costs can be optimized by using
BEMS (Building Energy Management Systems). All major stages of a renovation project are described
in the toolbox and put into practice by using new auditing tools e.g. review lists. The review lists
are introduced in appendixes.
The training and dissemination work contains blackboard information sheets, an Eco-Buildings e-learning
module, architectural student courses and a facility managers training based on the results of the
demonstration projects.
All reports and the BIT tool are available at:
