Referring to Figure 1, the high energy efficiency building design method of the present invention comprises the steps of setting a carbon reduction target setting module carbon reduction target value (S1); Collecting, by the environmental information collection module, environmental information regarding climate factors, solar radiation, and site characteristics (S2); The building appearance determination module simulates the environmental information to determine the optimal orientation of the building to minimize the heating and cooling load, and to determine the optimal shape of the building to achieve the carbon reduction target by predicting the energy load by the solar radiation amount (S3); The building envelope design module predicts the energy load due to the solar radiation to determine the envelope of the building to maximize its energy load, analyzes the amount of sunlight flowing into the interior and simulates the useful illuminance to minimize the lighting energy.

And designing the material of the inner wall of the building to achieve (S5).

First, in the high energy efficiency building design method according to an embodiment of the present invention, the carbon reduction target setting module sets a carbon reduction target value (step S1).

Recently, interest in the environment has increased due to global warming, and in 1997, the Kyoto Protocol, which mandates the reduction of greenhouse gases, was adopted. In 2007, Korea also participated in the reduction of greenhouse gases through the adoption of the Bali Roadmap. In particular, efforts are being made to improve the energy efficiency of buildings and to reduce greenhouse gases generated in buildings, which has led to the development of building energy management systems to improve energy efficiency and provide a comfortable space. Accordingly, there is a growing international interest in the development of a 'zero emission house', a futuristic environmental house aiming at minimizing carbon dioxide emissions at the building operation stage. But. Previously, energy management was not taken into account, and the future introduction of an energy management system in a designed building had a problem of having a certain limit in improving energy efficiency.

The present invention provides a high energy efficient building design method capable of achieving such a carbon reduction target value after setting the carbon reduction target value for such carbon reduction.

These carbon reduction targets are first set according to national policy, or generally accepted by industry, and then reassessed by assessing the availability and potential of carbon-free technology at the building design stage.

The present invention reflects energy efficiency in order to reduce carbon from the design stage of the building. Specifically, it provides a high energy efficiency building design by simulating environmental information such as climate factors, solar radiation and site characteristics, and energy saving element technology. And a renewable energy utilization technology can be combined to provide a 'zero emission house'.

Thereafter, the environmental information collection module collects environmental information on climate factors, solar radiation, and site characteristics (step S2).

The present invention collects environmental information for simulation of building design. Such environmental information includes climate factors, insolation and site characteristics.

Climate factors refer to the basic physical quantities that represent the climate, such as temperature, humidity, precipitation, clouds, and wind. Several climate factors are intricately linked to each other to exchange energy. These climate factors intertwine to maintain current climate and weather conditions. On the other hand, the factors affecting the spatiotemporal distribution of these climate factors are called climate factors. Climate factors include changes in the intensity and latitude of solar radiation, distribution of oceans and continents, currents, locations of high and low pressures, mountain ranges, and elevations. This is representative.

7 illustrates a climate analysis method using the 'Autodesk Weather Tool' software. After analyzing the climate of each region using climate analysis program, it can be applied to the plan to lay the groundwork for natural design, and the climate of each region can be prepared by using statistical data and climate data for 20 years. In addition, US, D.O.E data can be used to analyze the comfort zone (annual-weekly-daily), temperature, humidity, sunshine, and solar radiation of each data.

The amount of insolation refers to the amount of solar radiation coming from the sun (insolation) on the surface. The amount of insolation can be known by measuring the amount of energy radiated for one minute over an area of one square centimeter (cm 2) placed perpendicular to sunlight. On the other hand, the amount of sunlight refers to the amount of sunlight reflected on the surface or surface of a certain object and is distinguished from the amount of insolation. For example, if a tall building is too close, the shadows will fall and you will not be able to get enough sunlight.

Site characteristics refer to site limitations such as shadows due to nearby major buildings, and climatic factors around the site.

As buildings continue to influence and be affected by their surroundings, this information should be taken into account and taken into account when analyzing the load and energy consumption characteristics of the building.

In this case, the environmental information collection may use various sensor equipment and public statistical data, and the collected environmental information may be stored in the environmental information collection module using a database.

 The building appearance determination module then simulates the environmental information to determine the optimal orientation of the building to minimize heating and cooling loads, and predicts the energy load due to the solar radiation to achieve the carbon reduction target. Determine (step S3).

Air-conditioning load means the amount of heat required to keep the building air-conditioned while maintaining a pleasant condition. Calculation of this air-conditioning load is the most basic and most important in the process of air-conditioning design. Therefore, it is desirable to design buildings to minimize such heating and heating loads. The amount of sunshine varies with the altitude of the sun over time, and generally south-facing buildings are traditionally known to be sunny.

By simulating the environmental information it is possible to determine the optimal orientation of the building that can minimize the heating and cooling load. Depending on the latitude, altitude, and position of the sun in each region, the azimuth can be measured to be the most energy efficient. And although it is difficult to match exactly in the architectural plan, various plans are possible due to the characteristics of the area. An example of analyzing an optimal orientation reflecting energy efficiency and analyzing an optimal position to reduce heating and cooling loads based on average solar radiation and sunshine based on the 'Autodesk Weather Tool' is illustrated in FIG. 8.

In addition, the optimum shape of the building may be determined to predict the energy load by the solar radiation to achieve the carbon reduction target. 9 shows a simulation result for predicting the energy load due to the solar radiation using the 'Autodesk Ecotect 2011' software. Predicting the energy load by measuring the amount of insolation received on the part outside the building can determine the effective shape of the building, which can be an important indicator of building design.

In addition, the building envelope design module predicts the energy load due to the solar radiation to determine the exterior of the building to maximize the energy load, analyze the amount of sunshine flowing into the interior, and simulate the useful illuminance to minimize the lighting energy. By measuring the flow of airflow inside and outside the building, the location and size of the window are designed to facilitate air circulation and ventilation (step S4).

The envelope of the building may be determined such that the energy load is maximized so as to predict the energy load by the solar radiation and achieve the carbon reduction target. FIG. 10 shows a simulation result for predicting energy load due to insolation using 'Autodesk Ecotect 2011' software. The energy load can be estimated by measuring the amount of solar radiation received from the outside of the building, which can be an effective indicator of the building design.

In addition, the position and size of the window can be designed to analyze the amount of sunlight flowing into the interior and to simulate the useful illuminance to minimize the lighting energy. 11 shows the results of the sunshine analysis simulation using the 'Autodesk Ecotect 2011' software. Referring to FIG. 11, the position and size of a window may be designed by simulating the distribution of chief luminous intensity and useful illuminance necessary for an indoor unit. As a step to match daylight rate measurement to measure the amount of sunshine coming into the interior and interior useful illuminance, the position and size of the window can be determined, and the simulation measurement can be performed for the user's visual comfort and lighting energy saving.

In addition, by measuring the flow of air in and out of the building, the location and size of the window can be designed to smooth the air circulation and ventilation. remind By analyzing the amount of sunshine and simulating useful illuminance, the positions and sizes of windows designed to minimize lighting energy can be recalibrated or complemented. 12 and 13 show the results of the airflow analysis simulation using the 'Winair 4 / Flovent' software. The flow of air can be defined through direction, intensity and temperature. The flow of air (direction / intensity / temperature) can be determined inside and outside the building to determine the layout and size of the building and each room, This can help determine the overall shape of the building. In particular, referring to FIG. 13, not only the unit evaluation of individual buildings can be evaluated through the simulation of the flow analysis of the airflow, but also the evaluation of the arrangement of the complexes of the buildings.

Finally, the building interior wall design module simulates the environmental information to measure the flow of air in and out of the building to determine the layout of the building's interior walls to facilitate air circulation and ventilation, and predict the heating and cooling energy load of the building to reduce the carbon. Design the material of the inner wall of the building to achieve the target value (step S5).

The environment information can be simulated to measure the flow of air in and out of the building to determine the layout of the interior walls of the building to facilitate air circulation and ventilation, which share the location and size of the window with the design method and simulation. Therefore, the airflow analysis simulation results using the 'Winair 4 / Flovent' software of FIGS. 12 and 13 can also be used to determine the arrangement of the inner wall.

In addition, the material of the inner wall of the building can be designed to predict the heating and cooling energy load of the building to achieve the carbon reduction target value. After analyzing the climate of the area to set the requirements of the external conditions, after setting the internal conditions for each type of building, it is possible to predict the measurement of the energy consumption of the building and the internal annual temperature evaluation. Conditions are indicated, and these internal conditions must be given differently depending on the purpose, number of people, and location of each building. The energy consumption according to the predicted material can be measured for the heating and cooling energy load of the building according to the main structural members, and through this, the material of the inner wall of the building can be designed.

15 shows a simulation result of temperature distribution using 'IES / VE' or 'Autodesk Ecotect'. Through this, it is possible to measure the annual temperature of each room according to the temperature of the comfort zone and its comfort, and to estimate the internal and external temperature measurement of each room in a specific period and apply it in the design process.

FIG. 16 shows simulation results of energy consumption using 'IES / VE' or 'Autodesk Ecotect'. It is possible to measure the energy consumption according to the predicted materials for the heating and cooling energy loads of buildings according to the main structural members. And, in order to measure the energy load, it must match the materials of the exterior walls, interior walls, roofs, and floors, which must be changed according to the purpose of the building, and can be verified by simulation to facilitate this.

Through these steps, the present invention reflects energy efficiency in order to reduce carbon from the design stage of the building, and specifically provides a high energy efficiency building design by simulating environmental information such as climate factors, solar radiation, and site characteristics. It is possible to provide a 'zero emission house' by combining energy saving element technology and renewable energy utilization technology.

In addition, in a preferred embodiment of the present invention, the building design method having high energy efficiency further includes a step (S5 ') of introducing a renewable energy utilization system for achieving the carbon reduction target value after the step S4. It may include.

2 is a diagram showing a building design system configuration diagram having a high energy efficiency according to an embodiment of the present invention, a renewable energy utilization system is shown.

Although the reduction of carbon can be achieved through energy saving by the building design to which the energy saving element technology discussed above is applied, higher energy efficiency can be achieved by utilizing renewable energy utilization technology. Therefore, the design method of the present invention may further introduce a renewable energy utilization system to achieve the carbon reduction target.

Such a renewable energy utilization system refers to an energy utilization system that does not use existing fossil energy or nuclear energy, or produces and uses bioethanol fuel by recycling food waste generated by the operation of a building. Such a renewable energy utilization system is not particularly limited in its type, but may be used as a solar heating system, a solar power generation system, a solar power generation system, and a vertical axis wind turbine power generation system.

In addition, in a preferred embodiment of the present invention, the building design method having a high energy efficiency, the energy efficiency evaluation module evaluates the energy efficiency of the designed building and compared with the carbon reduction target value S3, S4 and S5 Determining whether or not to perform the step ( S6 ); may further include.

3 is a block diagram showing a building design system having a high energy efficiency according to an embodiment of the present invention, an energy efficiency evaluation module is shown.

The energy efficiency evaluation module evaluates the energy efficiency of the designed building, in order to prepare a way to control the amount of carbon generation and reduction generated in the house in the early stage of measurement design, and also to measure various energy loads. This is not a way to control the energy load throughout the building.

17 shows the results of evaluating carbon generation using 'Autodesk Green Building Studio', and FIG. 18 shows examples of measuring various energy loads.

The energy efficiency evaluation module compares the measured energy efficiency with the set carbon reduction target. If the energy efficiency of the designed building meets the carbon reduction target, there are some additional follow-up steps to finalize the building's design. However, if the energy efficiency of the designed building does not meet the carbon reduction target value, it may be possible to re-perform the steps S3, S4 and S5 through feedback. In addition, the renewable energy utilization system may be optionally introduced (see FIG. 4).
