Description

Building energy performance evaluation server and building energy performance evaluation program {Server for evaluating the energy performance of building and program for evaluating the energy performance of building}

The present invention relates to a building energy performance evaluation server and a building energy performance evaluation program, and more specifically, to a building energy performance evaluation server and building energy performance evaluation that can dramatically reduce the time required to evaluate the energy performance of a building. It is related to the program.

Conventionally, a building energy evaluator visited the building, entered survey items into an evaluation program, and evaluated the building's energy performance based on the input building data.

However, if building energy evaluators visit all buildings (7.3 million buildings nationwide) and evaluate the energy performance of buildings by entering all survey items one by one, it is expected to take approximately 30 years.

The government is implementing a policy to achieve carbon neutrality by 2050, but if it takes more than 30 years to evaluate the energy performance of buildings, the government's carbon neutrality target deadline will inevitably be postponed.

In other words, the conventional method of evaluating a building's energy performance by having building energy evaluators who visit the building input survey items one by one has clear physical limitations in meeting the deadline set by the government for carbon neutrality.

In the conventional building energy performance evaluation method, in order to meet the deadline set by the government for carbon neutrality, that is, to shorten the building energy performance evaluation period, more building energy evaluators must be deployed.

However, in order to meet the deadline set by the government, tens of times more building energy evaluators must be deployed than now, which could significantly increase costs and cause budget problems.

Above all, a building energy evaluator is an expert with special qualifications in the field. To become a building energy evaluator, basic professional knowledge in the field and a certain period of experience in the field are required.

In other words, only a small number of people who have passed strict qualifications in the building field can become building energy evaluators.

Therefore, more than the cost aspect, there is a more difficult problem in securing the desired number of qualified building energy evaluators in a short period of time.

In other words, at this point, in order to meet the carbon neutrality deadline set by the government, it may be virtually impossible to increase the number of building energy evaluators dozens of times compared to now.

One technical problem that the present invention seeks to solve is to provide a building energy performance evaluation server and a building energy performance evaluation program that can dramatically reduce the time required to evaluate the energy performance of a building.

Another technical problem that the present invention aims to solve is a building energy performance evaluation server and The goal is to provide a building energy performance evaluation program.

Recently, problems that humanity must solve on a global level, such as global warming and depletion of fuel resources, are constantly occurring.

In particular, interest in building energy reduction is increasing worldwide, and individual countries are planning or conducting energy performance evaluations for buildings in order to establish energy reduction plans in the building sector and prepare specific action plans.

Accordingly, our government also announced a 2050 carbon neutrality (Net ZERO) strategy.

Referring to Figure 1, carbon neutrality is a policy or global campaign that reduces actual carbon dioxide emissions to zero by taking measures to absorb as much carbon dioxide as it emits.

Figure 2 is statistics on energy usage by sector in 2020 announced by the Korea Energy Agency, showing energy usage by industrial sector, building sector, and transportation sector.

Here, the total energy consumption was announced as 230 million (TOE; Tonnage of Oil Equivalent), and 62% of the total energy consumption was announced to be used in the industrial sector, 21% in the building sector, and 17% in the transportation sector. . And the total power consumption was announced to be 570,000 GWh and carbon emissions to be 730 million tCO2eq.

At this time, the annual energy consumption of the building sector, which accounts for 21% of total energy consumption, was announced to be 40,800 TOE, the annual power consumption to be 119,000 GWh, and the annual carbon emissions to be 1.5 tCO2eq.

Likewise, according to statistics on energy usage by sector in 2020 announced by the Korea Energy Agency, it can be seen that energy usage and carbon emissions in the building sector are significant.

To reduce greenhouse gas emissions, the government implemented the Framework Act on Carbon Neutrality and Green Growth to respond to the climate crisis on March 26, 2022.

Accordingly, the government has established a goal of reducing national greenhouse gas emissions by 35% or more compared to national greenhouse gas emissions in 2018 by 2030, and has set a 20-year planning period to achieve the national vision and mid- to long-term reduction goals. A national carbon neutral green growth basic plan must be established and implemented every five years.

In addition, special mayors, metropolitan mayors, special self-governing mayors, provincial governors, and special self-governing provincial governors have established city and provincial carbon neutral green growth basic plans with a 10-year planning period of 5 years, taking into account the national basic plan and the regional characteristics of their jurisdictions. It must be established and implemented each time.

In addition, mayors, county governors, and district heads establish and implement city, county, and district carbon neutral green growth basic plans every five years with a 10-year planning period, taking into account the national basic plan, city, provincial plans, and regional characteristics of their jurisdictions. shall.

At this time, as a government policy for carbon neutrality in the building sector, a carbon neutral scenario in the building sector was jointly announced on October 18, 2021 by relevant ministries.

In the scenario, we plan to reduce energy by about 30% by improving the energy usage intensity of energy facilities and devices, such as strengthening energy consumption efficiency and expanding the labeling system, and by expanding the penetration rate of the optimal energy use control integrated management system by 100%, reducing energy use by 2% to 5%. We plan to reduce the energy consumption by more than 30% compared to 2018 by achieving 100% zero energy building grade 1 for new construction and energy efficiency rating through green remodeling for existing buildings.

Referring to Figure 3, in order to reduce greenhouse gases by 32.8% by 2030, the government is gradually and mandatorily converting buildings with a total floor area of 500 m2 or more to ZEB (zero energy buildings) by 2030, as well as energy conservation through green remodeling. We are planning to build an efficient building.

Specifically, it is planned to convert public buildings over 1,000 m2 to ZEB 5 in 2020, and public buildings over 500 m2 and apartments (public) with more than 30 households to ZEB 5 in 2023.

In addition, in 2024, it is planned to convert public buildings over 500㎡ to ZEB 4 and apartment houses (private) with more than 30 households to ZEB level, and in 2025, private houses over 1,000㎡ are planned to be converted to ZEB level. Planning.

In 2030, public buildings over 500 m2 are planned to be converted to ZEB 3, private buildings over 500 m2 are planned to be converted to ZEB level, and in 2050, public buildings over 500 m2 are planned to be converted to ZEB 1. .

Here, ZEB 1 is a certification grade for buildings with an energy independence rate of 100% or more, and ZEB 2 is a certification grade for buildings with an energy independence rate of 80% or more but less than 100%.

In addition, ZEB 3 is a certification grade for buildings with an energy independence rate of 60% or more but less than 80%, and ZEB 4 is a certification grade for buildings with an energy independence rate of 40% or more but less than 60%.

And ZEB 5 is a certification level for buildings with an energy independence rate of 20% or more but less than 40%.

In this way, the certification system that grants certification grades to buildings was established to expand the distribution of buildings with high energy performance and induce effective energy management by providing quantitative and objective information about the energy performance of buildings.

The above certification system evaluates and certifies the energy efficiency of buildings in accordance with Article 17 of the 「Green Building Construction Support Act」, 「Rules on Building Energy Efficiency Grade Certification」, and 「Building Energy Efficiency Grade Certification Standard」, and relaxes building standards and Provide incentives such as tax benefits.

In order to promote the distribution of buildings with excellent energy efficiency and saving, the Ministry of Trade, Industry and Energy began operating the above certification system based on Article 21 of the Energy Use Rationalization Act and the regulations on building energy efficiency grade certification in 2001, and has been in operation since 2010. It is jointly operated by the Ministry of Land, Infrastructure and Transport and the Ministry of Trade, Industry and Energy.

In 2013, the “Green Building Construction Support Act” was enacted, and the sub-regulations “Rules on Building Energy Efficiency Grade Certification” and “Building Energy Efficiency Grade Certification Standards” were newly enacted and revised, expanding the scope of obligations for public buildings and existing standards. Certification standards for buildings have been established.

Previously, newly-built apartment buildings (2001) and newly-built office buildings (2010) were subject to certification, but now, new construction and all existing uses (single-family homes, apartment buildings, dormitories, office facilities, and other cooling and heating areas) are voluntarily applied by building owners. This was expanded to buildings larger than 500㎡ (effective September 1, 2013).

However, according to the Ministry of Trade, Industry and Energy’s “Regulations on the Promotion of Rationalization of Energy Use by Public Institutions,” buildings ordered by public institutions (apartment houses grade 2, office buildings grade 1 or higher) are subject to obligation.

The certification standard for the above certification system analyzes design books for buildings, calculates energy consumption for heating, cooling, and domestic hot water, and carbon dioxide emissions, and evaluates them into 10 grades (1+++ ~ 7) according to energy performance.

For energy calculation, an algorithm prepared based on ISO-13790 and DIN V 18599 (comprehensive calculation of heating, cooling, hot water supply, lighting, ventilation, etc., divided by floor area) is used, as shown in Calculation 1 below.

[Calculation Formula 1]

Here, in the case of residential buildings without air-conditioning equipment (single-family houses and apartment complexes excluding dormitories), the air-conditioning evaluation items are excluded.

Additionally, the primary energy requirement per unit area can be calculated by multiplying the energy requirement per unit area by the primary energy conversion coefficient.

Additionally, renewable energy production can be reflected in energy requirements and included in efficiency rating evaluation.

Table 1 below shows the building energy efficiency certification grades.

Rating residential building Buildings other than residential Primary energy consumption per unit area per year (kW/㎡·year) Primary energy consumption per unit area per year
(㎾/㎡·year) 1+++ less than 60 less than 80 1++ More than 60 but less than 90 Above 80 but below 140 1+ More than 90 but less than 120 140 or more but less than 200 One 120 or more but less than 150 200 or more but less than 260 2 Above 150 but below 190 Above 260 but below 320 3 Above 190 but below 230 Above 320 but below 380 4 Above 230 but below 270 Above 380 but below 450 5 Above 270 but below 320 Above 450 but below 520 6 Above 320 but below 370 Above 520 but below 610 7 Above 370 but below 420 Above 610 but below 700

In Table 1 above, residential buildings are apartment buildings excluding single-family homes and dormitories. Additionally, non-residential buildings are buildings other than residential buildings.

Meanwhile, the certification of a building that has received a rating of out of grade is indicated as out of grade, and the primary energy consumption, which is the standard for calculating the grade, is a result of reflecting the correction coefficient for each use, and may differ from the actual primary energy consumption result calculated through Equation 1 above. .

Looking at the certification process of the above certification system, first, the applicant can fill out the completion document and application form and submit them to the certification agency.

Accordingly, the certification body can receive the application and check the site upon self-certification. The certification body can then assess the energy efficiency rating for the building, write an assessment report, and issue a certificate.

The building energy efficiency rating certificate includes building overview (building name, completion date, address, etc.), certification overview (certification number, evaluator, certification agency, operating agency, validity period), certification grade, and building energy efficiency rating evaluation results (see Figure 4). ), shows the evaluation results by energy use (energy demand, consumption, primary energy consumption, _CO2 emissions per unit area for cooling, heating, hot water supply, lighting, and ventilation).

The issued certificate is provided to the applicant, and accordingly, the applicant obtains the certificate. In addition, the issued certificate is sent to the operating agency, and the Ministry of Land, Infrastructure and Transport and the Ministry of Trade, Industry and Energy report the certification results on a quarterly basis.

Here, the applicant may be a building owner, building owner, or constructor (limited to cases where the building owner or building owner agrees to apply for certification).

At this time, preliminary certification means certifying the energy efficiency level based on the results of evaluation through design books before the building is completed.

In addition, self-certification means certifying the energy efficiency level based on the results of evaluation through design documents prior to approval of completion of the building. And the certification validity period is 10 years from the certification date.

Meanwhile, the total building energy consumption system implemented by the government is a method of calculating based on the total energy consumption, breaking away from the energy saving standards for each part of the building, such as the exterior walls, windows, roof, and floor, and calculating the amount used per unit area in the building for one year. It is a system that encourages design of energy consumption below a certain standard.

In Seoul, the building sector accounts for 60% of energy consumption. In order to reduce energy demand in this sector, promote the spread of green buildings, and pursue a design basis for low-energy consumption buildings, Seoul City is implementing the “Building Energy Consumption Total System” on a pilot basis.

The “Green Building Design Standards” (enacted on April 1, 2013) are the relevant regulations, and the basis for promotion includes the “Green Building Construction Support Act,” “Energy-Saving Design Standards for Buildings,” and “Comprehensive Measures to Reduce One Nuclear Power Plant.”

The building energy consumption cap system is applicable to buildings with a total floor area of 500 m2 or more, buildings subject to the submission of an energy conservation plan to apply for a building permit and change of use in accordance with Articles 11 and 19 of the Building Act, and residential buildings (apartment houses with 100 or more households). and non-residential buildings (business facilities with a total floor area of 3,000 m2 or more).

The standard for the building energy consumption system is to check the total energy consumption when applying for architectural review or approval or permission, and to evaluate the annual primary energy consumption per unit area, such as heating, cooling, hot water supply, lighting, and ventilation. The certification standard is less than 190 kWh/㎡·y for apartment buildings and less than 280 kWh/㎡·y for business facilities.

Check the data entered into the BESS (building energy simulation for Seoul) program (walls, window thermal transmittance, lighting load, cooling, heating load, etc.) at the time of building review or approval, and check whether the total energy consumption standards are met for each use. Data is stored and managed for each project (building). When completing or approving use, the total energy consumption calculation input data and completion documents are checked for each project (building), and if it is within the total energy consumption standard, completion or use is approved.

The BESS's Input Data Sheet contains the project overview, heat source equipment, insulation performance, new and renewable energy, and information on the zone, and the Output Data Sheet contains energy usage analysis, energy demand analysis results (monthly cooling and heating requirements), 1 It includes vehicle energy consumption analysis results (heating, cooling, hot water supply, lighting, ventilation, new and renewable energy, primary energy usage, greenhouse gas generation, total energy consumption), green design building design standards review items, etc.

There are standards for the total energy consumption system for buildings in Chapter 5, Article 21 (Evaluation of Energy Consumption of Buildings) and Article 22 (Method of Evaluation of Energy Consumption of Buildings) of the 「Building Energy Saving Design Standards」.

In order to introduce a total energy consumption system for buildings, the “Building Energy Saving Design Standard” was revised. This is to actively encourage building designs with high energy-saving performance. Before the revision, energy standards were set for each part, such as windows and floors, so the energy performance of the building was not identified during design. Accordingly, the permit standards for each section were improved so that the energy performance of the building could be calculated in total.

A building energy consumption evaluation report evaluating primary energy consumption, etc. for buildings with a total floor area of 3,000 square meters or more that are similar to business facilities and other energy consumption characteristics and usage conditions pursuant to Article 3-4 of the Enforcement Decree of the Building Act. must be submitted.

However, if the preliminary certification of the building energy efficiency class has been obtained pursuant to Article 11 of the “Rules on Building Energy Efficiency Class Certification,” it may be replaced with the preliminary certification of the building energy efficiency class.

When applying for a construction permit for a target building, the primary energy consumption per unit area per year for heating, cooling, hot water supply, lighting, and ventilation is evaluated in accordance with international standards such as ISO 13790.

Meanwhile, the conventional method of assessing the energy performance of more than 7.3 million buildings nationwide by manually entering survey items by building energy evaluators who visit the buildings makes it impossible to meet the carbon neutrality deadline of 2050 set by the government. does not exist.

In order to solve this problem, the building energy performance evaluation server (100 in FIG. 5) according to an embodiment of the present invention uses machine learning and AI (Artificial Intelligence, The energy performance of buildings can be evaluated through artificial intelligence (AI).

The time required to evaluate the energy performance of a building can be dramatically reduced. For example, it was predicted that it would take approximately 30 years to evaluate the energy performance of all buildings using the conventional method, but according to an embodiment of the present invention, the required period can be dramatically shortened. For example, through the building energy performance evaluation server (100 in FIG. 5) according to an embodiment of the present invention, the period required to evaluate the energy performance of all buildings can be shortened to 0.5 years.

That is, according to an embodiment of the present invention, the energy performance evaluation of all buildings can be completed within the carbon neutral deadline set by the government, and measures such as green remodeling that can prevent energy waste according to the energy performance evaluation results can be taken.
