Implementation of construction-installation works for the Flora Burgas Expo Centre, thus ensuring less energy consumption and greater use of RES.
Located on the Black Sea, Burgas is the fourth largest city in Bulgaria, and is an important centre for industry, transport and tourism. The city has the biggest port in Bulgaria and is the main hub of the Bulgarian fishing and fish processing industry.
In 2013, the City of Burgas decided to replace the existing textile exposition pavilion with a modern building, which could be used year-round for a wider variety of events.
The most economically advantageous tender was awarded the contract based on the following:
- Price (50 points);
- Technical Proposal (40 points);
- Proposed Deadline for finalization of the works (10 points).
Within the technical proposal, a section related to ‘protection of the environment’ was also included with a total value of 10 points, so that proposed measures for protecting air, water, soil, etc. during the construction process could be accounted for when comparing tenders.
The design of the resulting Flora Exposition Centre building incorporates photovoltaic (PV) panels, a green roof (or living roof) and wall features, rain-fed irrigation, utilisation of natural and light-emitting diode (LED) lighting, and energy efficient building systems and materials. Its use of sustainable architecture principles has not just improved the building’s environmental impact, but also suits its surrounding landscape and complements its location in Burgas’ well-known park the ‘Sea Garden’.
2,802,970.39 BGN VAT included
Evidence of success
A total of 33 PV panels have been incorporated into the Flora Centre’s design, supplying 15,733 (kwh) per year. Energy efficient LED lighting has been installed, and the building has also been oriented to maximise the use of natural light. The building’s air conditioning and ventilation system are also high-performance and make use of heat recovery. The building materials have been chosen with heating and cooling needs in mind. Low-emissivity glass has been used to prevent overheating.
Potential for learning or transfer
Applying passive measures led to energy savings, increased comfort for users, and created a more sustainable and economically viable building in the context of the whole building life cycle.
Shading of facades is often neglected in the design stage of new buildings, but this building demonstrates that roof and wall landscaping is easily applied, and is an effective way to increase comfort of building users, especially during summer months. Overall, this procurement demonstrates that the successful combination of energy efficient measures and attractive design is possible, without making compromises for any of them.
