SRI ASSESSMENT CASE STUDY: GREEN POINT BUILDING

SRI ASSESSMENT CASE STUDY: GREEN POINT BUILDING

SRI ASSESSMENT CASE STUDY: GREEN POINT BUILDING

SRI assessment methodology, as defined by the EU commission, is quite ambitious about smartness of the buildings if we analyzed the defined functionality levels for each technical domain. There are lot of automatic controls, sensors, flexibility… And it should be ambitious, since we are aware of the technological development and rising awareness of EU citizens about energy efficiency, CO2 reduction and climate protection. We also know that buildings generate large amounts of gas emissions, and we need to do something to reverse these trends.

Renovation of the buildings is a long-term and expensive process, but fortunately we could also use smart technologies to control our consumption, which tends to be cheaper and not so complex solution.

But how smart are our buildings today and how could they be smarter? If we have smart buildings does that mean that we are more energy efficient?

The first step in answering is to check where we are, establish some ground levels and then plan the improvements.

SRI-ENACT project spent a lot of human resources to prepare for the assessment phase of the buildings around EU to execute the first step. It is quite an interesting step where we will get the first insights into smartness of the buildings on the most comprehensive assessment ever made, and be able to answer previous questions, at least on general level.

The best illustrations are real examples.

 

THE BUILDING

Our example is the Green Point Building that was built in Austria from 2018-2020 and has total are approximately 11.000 m2 (apartments and offices) https://green-point.at.

The building is characterized by the very high level of insulation (A+ energy performance certificate) and own energy production: solar panels on the roof and on the balconies (225 kW) with battery storage. The building has a connection to the district heating network for heating and domestic hot water (DHW). Although it is a new, modern building, it does not have colling equipment (only individual A/C for some offices), nor ventilation (only natural). It was considered to have exceptional insulation to provide good protection from high temperatures, which do not happen often in that geographical area.

There are also EV charging points installed, DC with max power 50 kW and AC with max power 22 kW. All energy loads and sources are monitored by the modern BACS allowing residents to have insight into consumption and profiles.

Additionally, apartments also have control of window shading based on the time of day.

To improve the safety and comfort of residents, the modern system for the alarming in case of water leakage is installed.

Based on the information, we can tell right away that the building was built in a smart way with the basic smart technologies applied.

ELECTRICAL ENERGY (EV charging, Lighting)

Due to the high insulation and lack of larger physical loads (no A/C), the consumption of electrical energy is very low. The total production of PVs could be above of the total demand, on maximum levels, during when most of the produced energy is supplied back to the grid.

EV charging is controlled not to exceed the maximum allowed power and to distribute the charging power between chargers, and users can have insight using mobile app.

Public spaces, like corridors, stairs and similar are equipped with motion sensors for lighting.

 

HEAT ENERGY (Heating, domestic hot water)

Heat energy is used via the connection to district heating system in the city. The building has its own heat exchanger and supplies the apartments and offices with the energy for heating and domestic hot water. The price of heating energy is high but due to good insulation, it is not used in large amounts. Heating is controlled centrally in each apartment, as a standard solution.

 

MONITORING AND CONTROL:

All energy meters are monitored by the BACS system. The system comprises of single control computer collecting the meter data and cloud-based software for presentation and analysis.

 

ASSESSMENT

The assessment was done using a new online tool developed in line with the EU proposed SRI methodology, B option (full set of services). The data have been entered after the site visit with two main domains not included: Cooling and Ventilation. Those domains do not affect the SRI scoring and are not mandatory, but also do not contribute to the comfort and well-being. Other domains have functionalities on the first and, maximum, second level, resulting in SRI score of 20%. According to information about SRI assessments the maximum score for real life buildings in EU was “only” 65%. At least so far. Just to remind you that we already qualified SRI methodology as optimistic, but future proof.

As we have mentioned previously, the building has high energy efficiency (also reflected in the best impact SRI score of 35,5%), it is almost self-sufficient, even without highest smart technologies installed, and provides perfect basis for the improvements.

Due to the installed solar panels and battery storage, electrical energy is the best scored domain (56,6%), but since heating domain bears the highest weighting factor in Austria, the resulting score is degraded.

This assessment exercise was very useful in the way that we have enlightened what SRI assessment is and what to expect from the resulting scores. It states that smart technologies are not reserved for the newest buildings and that small investments could make us smarter, more efficient, more flexible and supporting the energy transition. There should be no disappointments with results in any direction, only boost for the new steps and new improvements.

For the Green Point building, implementation of smart technologies for optimal control of energy flows and flexibility services to the grid should significantly increase the SRI score, together with the possibility to install more RES in form of heat pumps to also allow higher comfort. We will stay in contact to follow them in their new ventures and check for the SRI again. We are hoping for bigger numbers!

Results of the first SRI testing in the building sector in Bulgaria

The first SRI and SRI-ENACT Assessment Toolkit testing in Bulgaria was successfully carried out by the BSERC auditors in February-March 2024 on four different functional building types in four cities – Sofia, Plovdiv, Lovech and Sandanski. The locations are shown on the map.

The SRI testing procedure in the country is officially recognised and supported by the Ministry of Energy and the Sustainable Energy Development Agency.

The four buildings assessed according to their SRI level are as follows:

Office Buildng-2 Garitage Park in Sofia,… Total SRI Score 57.1%/Class D

Drama Theater  in the town of Lovech,.….… Total SRI Score 33.9%/Class F

Hospital „Saint George“ Block-1  in Plovdiv,…Total SRI Score 30.0%/Class F

Kindergarten “Dora Gabe” in Sandanski, … Total SRI Score 25.8%/Class F

The office building is new (built in 2019, BREEAM certified) and the other three buildings have been renovated.

After the upcoming training of 13 certified auditors to assess the SRI on a larger scale, the test will be extended to a total of 130 different buildings in Bulgaria.

The feedback from the SRI auditors on the use of the SRI-ENACT Assessment Toolkit was very positive. Their comments are summarised below:

  • The manual for registration and operation of the SRI-ENACT Assessment Tool has been prepared in the best possible way for the auditors/users.
  • The use of the SRI Assessment Toolkit software is easy and takes a short time if the required inputs of the analysed building are prepared in advance (e.g. from the building’s energy efficiency assessment report).
  • The tool’s menus are user-friendly and the dynamic pop-up auxiliary windows facilitate the processing of input data and the corresponding calculations of local SRI indicators for each of the building’s technical systems, as well as the building’s aggregated SRI.
  • The detailed catalogue of 54 intelligent control technologies introduced in the software is a significant contribution to speeding up the work of determining the levels of functional perfection of the building’s technical systems (domains).

Evaluation of the office building ‘Energy Centre Bračak’ – here are our first insights!

Evaluation of the office building ‘Energy Centre Bračak’ – here are our first insights!

Throughout our project, our project consortium has been working on pilot evaluation of the SRI-ENACT methodology and platform for last several months. Main goals of this aspect of our project are to perform evaluation, testing and improvement of created SRI assessment toolkit, but also to generate evaluation reports of assessed buildings and define replication guidelines. The following text gives a short overview of performed and future activities to achieve presented goals.

To perform successful SRI assessments, the project consortium must build the capacity of SRI Auditors to transfer the knowledge about the SRI methodology and toolkit. Throughout the project, a decision was made that training of future SRI Auditors should be distinguished between internal auditors (employees of project partners) and external auditors.

On November 28, 2023, the project marked a significant milestone with its inaugural online training program for internal auditors, attracting 34 participants from 8 partner countries. This training equipped future internal SRI experts with the knowledge and skills needed to conduct detailed and accurate building assessments using the toolkit. It is expected that one more training session for internal SRI Auditors will be carried out in following months after finalising SRI toolkit and expanding its functionality. On the other side, a series of trainings of external SRI Auditors will kick off in April 2024 where three sessions will be conducted to transfer knowledge to experts outside of our partner organisations.

After finalization of crucial training of internal SRI Auditors, partner organisations were equipped with knowledge to start the pilot pperation – SRI assessment programme, an ambitious plan to assess more than 1 000 buildings until the end of the project. As this large task is one of the most important aspects of the project and due to its scope, it will be carried out in 3 distinct cycles, with the first cycle scheduled for completion by the end of February 2024.

During this initial test phase, each partner country relies on internal SRI auditors to evaluate 3-5 pilot buildings, resulting in a valuable dataset of at least 24 building SRI assessments. Throughout this test phase, the focus is also put on gathering important feedback about the toolkit functionality and recommendations for improvements.

One of examples of SRI assessment can be highlighted where, after successful training and commencement of evaluations, REGEA’s internal auditors conducted the initial SRI assessment of the Bračak Energy Center in Bračak, Croatia on January 24, 2024. This historic nZEB building, transformed into a modern center boasting impressive energy efficiency, achieved a score of 39.5% in the SRI assessment, which classifies it in the SRI class E. Although the Bračak Energy Center has a large commitment to sustainable practices, results of the assessment showed that there is still a plenty of room for improvements in terms of smart building concept, according to official SRI methodology which is valuable feedback for future development. The valuable insights and data gathered from all 24 evaluations of the pilot buildings will be highlighted in a public document that will be published in September 2024.

As for the future activities, from April 2024 a second cycle kicks off in which internal SRI auditors will continue to carry out assessment of pilot buildings. In addition to work performed by partner organisation, external SRI auditors will also start with their assessments, all to reach a goal of 1 000 SRI assessed pilot buildings.

In addition to the training programme and assessments, the project has also organized three informational events, one per following countries: Austria, the Czech Republic, and Croatia. These events provided a valuable opportunity to present the SRI-ENACT project to a wider audience, raise awareness of the importance of sustainable and energy-efficient building practices, introduction into planned SRI assessment programme (Pilot operation) and attract potential external SRI auditors. It is expected that several more informational events will be carried out in following months in all partner countries.
