For Sustainable High Performance Green Buildings; "Provolta Energy Energy Management-Operating System"
With the effect of energy efficiency incentive regulations in managing and creating real sustainable green buildings, sustainable energy efficiency practices in enterprises and buildings are being talked about extensively today; the concept of monitoring energy consumption in the building is replaced; the integrity and manageable building has been left to energy performance analysis.
Optimization of energy consumption of existing enterprises-buildings, the impact of sustainable high-performance green buildings and energy efficiency improvement efforts on existing buildings, and depreciation and return times to be transparently monitored; the need for cheap, modular, easy-to-use, flexible and scalable software has emerged.
In addition, the emerging "energy efficiency consulting companies (EVD)" and "ESCO" in our country; energy service company" and "energy performance contracts (EPC); energy performance contract" models, meeting project financing through energy savings and efficiency to be provided in the building, risk analysis of energy efficiency applications and post-implementation double-sided (both energy efficiency service/product supplier and building-business owner) building energy performance monitoring has been required.
This necessity; periodic building energy studies with manual devices required the evolution of continuous and real-time energy performance analysis software.
Single-point consumption monitoring has been replaced by artificial intelligence algorithms used to analyze data from many distributed sub-meters and sensors, past-time energy performance trends, and forward-looking energy forecasts.
Building Energy Consumption Tracking
In addition to taking building energy consumption flow trends; it is also important to make the building understandable by energy managers, technicians and financial experts.
The complex and technical interfaces of the current systems are not able to put the raw data collected into the actionable format. Energy performance analysis tools offered to businesses and organizations with user-friendly interfaces; it both raises awareness of energy efficiency and can clearly consider the potential impact of possible energy efficiency improvement efforts from a technical and financial point of view.
The next generation of energy data analysis software, consisting of integrated modules and multidimensional architecture, shapes the building energy efficiency and sustainable high performance green building market.
"Provolta" developed by Reengen Company, which was established in 2012 with the support of "Techno Enterprise" grant from the Ministry of Science, Industry and Technology; meeting the market requirements of the 21st century described above; measurement-management and optimization triangle.
Software that processes the data it collects with an analytics engine that works entirely through the "cloud", providing applications for building energy efficiency; demand-side management (DSM; Demand Side Management).
As well as being able to independently connect hardware with different measuring devices; Knx is able to transfer data in real time by connecting to the databases of building automation systems that interact with LonWorks and BACnet protocols.
It is also one of the temperature, de-de-de- and CO2 sensor modules developed by Reengen; Internal air quality parameters can be monitored via the "ZigBee wireless communication protocol".
Energy Analysis Program
"Energy-Plus" software, an energy analysis program developed by the U.S. Department of Energy (DOE), has been moved to the "cloud"; Integrated operation into the "Provolta" infrastructure.
The real-time energy analyzer blends meter, thermostat and sensor data with modeling-based building energy simulation results, using it to predict energy consumption sub-breaks with high certainty.
Under normal circumstances, the building energy modeling process, which lasts for a very long time, is performed on high-performance servers running parallel to the "cloud", resulting in minutes.
The forward energy performance of mechanical, outlet and lighting loads and data centers in commercial buildings and businesses is estimated using historical consumption data and real-time sensor data as inputs, and energy health report cards and industry-specific reports can be presented by comparing them with reference profiles created by modeling.
It includes customizable interface functions, starting with the building visitor according to the hierarchical level of the users, including modules that the general manager of the institution-business will want to see.
In addition to the web application, it creates energy efficiency and renewable energy awareness in building users, transforming building energy efficiency work into an all-out corporate sustainability study; touch kiosk, LCD and mobile applications are also available. "Provolta"; provides energy savings of 10-15% thanks to the awareness it creates in users, adjusting comfort conditions, changing usage habits and real-time feedback.
"Provolta", which brings the concept of online continuous-sustainable energy study for green buildings, commercial buildings and public buildings; building portfolios for multi-branch enterprises can be managed through a single platform-center and benchmarks can be made between similar buildings.
Thanks to its rich data bank, it can use industry-specific energy consumption trends-needs as supporting data in energy performance analysis of bank branches, hospitals, shopping malls, supermarkets, business centers, public housing, hotels, green buildings, green campuses, academic institutions and public buildings.
Learning Algorithms in Energy Monitoring
By learning about energy usage trends, "Provolta" offers the results of dynamic and continuous comparisons with reference building models with rich report format options developed for different user levels.
In particular, the necessary measurements and reportings for energy consumption, comparison with other such, comfort conditions, carbon footprint, ISO 14025 Carbon Management System, ISO 50001 Energy Management System are available as an option.
User-assigned information, reports, and alarm statuses; Via SMS and e-mail, with various notifications; dynamically improves savings-efficiency and comfort conditions again.
Software that learns the electrical-thermal and comfort dynamics of the building, according to hourly weather forecasts and the number of building users; optimize-maximize energy performance.
Historical data is used to improve software algorithms. In the future, this model is integrated into dynamic energy pricing, resulting in much more value-added results.
Especially through hourly energy consumption data to be obtained as a result of the integration of smart meters; energy performance studies that cannot be done with static data at the time can be done.
Reengen, a core team with academic backgrounds, mostly graduates of Electrical and Electronics and Computer Engineering at Middle East Technical University, studies the analysis of complex data using artificial intelligence and data mining-based methods and the application of wireless sensor networks to building energy efficiency.
The team's biggest success story is the director of the Center for Energy, Environment and Economics at Özyeğin University in Turkey. M. He created his role in the European Union FP7 Project "NEED4B : New Energy Efficient Buildings for Demonstrations" conducted by Pinar Mengüç. Considering the ball-only effect of "Provolta", özyeğin University Campus; Up to 25% energy savings have been made. Currently, 2 green buildings, branches of 2 banks, 1 university campus, 6 chicken farms have started to be used.
Provolta has been a key stone in the "EPC" (Energy Performance Contract) model, which breathes new life into energy efficiency financing.
In energy efficiency projects where businesses are guaranteed 5-10 years of energy performance, the mutual monitoring of energy performance of ESCO Companies and operators-building owners such as VEN ESCO through various environments makes it significantly easier to measure and confirm EPC implementation.
ESCO companies can thus make their savings-efficiency-comfort potentials in the business much clearer, while the maximum savings-efficiency impact of the right engineering and applications, appropriate technologies, for possible energy efficiency improvements; with web tools, it can be calculated easily and at the least cost.
