Detail: more money for photovoltaics


The State Court of Audit (LRH), on its own initiative, examined the energy efficiency of state buildings and came to the conclusion that the renovations undertaken are showing a positive impact. The country should go ahead with the expansion of photovoltaics in a targeted manner and spend money on it.

The presentation of energy data of state buildings should be completed in Energy Monitoring, it said in a press release on Wednesday.

redefine energy strategies

Since 1994, the country has adopted a number of energy strategies to expand renewable energy and reduce consumption. “The situation in both the national and European frameworks is constantly changing; this is why existing energy strategies must be combined or reformed,” explained Frederick Palmer, director of the LRH.

Big consumers missing in energy accounting

In energy accounting, all buildings owned by a state real estate company and used by state offices are recorded, but not other buildings of the state holding company, such as technical colleges or objects of a health holding company. This would mean that large consumers such as hospitals would be missing out.

Provide budgetary funds for PV systems

The country should proceed with the expansion of photovoltaic capabilities in a targeted manner. The OOH photovoltaic strategy envisages a tenfold increase in photovoltaic power generation from 345 gigawatt hours (GWh) in 2019 to 3,500 gigawatts by 2030 in 2030. There is a demand for a five-fold increase in capacity for the country’s buildings. To do this, all appropriate rooftops and open spaces would have to be used and photovoltaic roofs would have to be erected on about two-thirds of the state’s parking areas. “Political decision-makers will also have to position themselves clearly and make available at least 24 million euros of extra-budgetary funding,” Palmer said.

Renewal rated positive

LRH rated renewables positively, as overall energy consumption was reduced, although usable areas continued to increase. When examining six properties with different building and building services concepts based on their consumption standards, it was shown that buildings with high levels of building services equipment do not achieve specified values ​​for heating energy requirements , especially properties with passive houses are the norm. They also have comparatively high power consumption.

Harness the Experience from Energy Monitoring

New buildings or refurbishment of existing buildings with simple building technology concepts will often result in closer to target values. The state should use this experience gained from energy monitoring for future planning of construction projects. For this a comprehensible analysis of the systems installed is important. For this reason, the LRH recommends evaluating the parameters to be used as a basis in the planning process. “Based on the data obtained in this way, energy consumption can be assigned to specific control settings or to particular usage behaviors,” Palmer said.
