Figure 1 is a diagram showing the configuration of a building design system with high energy efficiency according to a preferred embodiment of the present invention.

Referring to Figure 1, the high energy efficiency building design method of the present invention includes the steps of setting a carbon reduction target value by a carbon reduction target setting module (S1); A step (S2) in which the environmental information collection module collects environmental information about climate factors, solar radiation, and site characteristics; A step in which the building exterior determination module simulates the environmental information to determine the optimal orientation of the building to minimize heating and cooling load, and predicts the energy load due to solar radiation to determine the optimal shape of the building to achieve the carbon reduction target.

Includes a step (S5) of designing the material of the inner wall of the building to achieve.

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

Recently, interest in the environment has been increasing due to global warming issues, and in fact, the Kyoto Protocol, which mandates greenhouse gas reduction, was adopted in 1997, and Korea also participated in greenhouse gas reduction with the adoption of the Bali Roadmap in 2007. In particular, efforts are being made to improve the energy efficiency of buildings and reduce greenhouse gases emitted from buildings, which has led to the development of a building energy management system to increase energy efficiency and provide a comfortable space. Accordingly, international interest in the development of 'zero emission houses', futuristic environmental housing that aims to minimize carbon dioxide emissions during the building operation stage, is growing. however. Previously, introducing an energy management system into a building designed without energy management in mind had certain limitations in improving energy efficiency.

In order to reduce carbon, the present invention provides a high energy efficiency building design method that can achieve these carbon reduction targets after setting them.

These carbon reduction targets are first set as a target in accordance with national policy or a target generally accepted in the industry, and then readjusted by evaluating the availability and potential of carbon-free element technology at the building design stage. The present invention reflects energy efficiency to reduce carbon from the design stage of the building. Specifically, it provides high energy efficiency building design by simulating environmental information such as climate factors, solar radiation, and site characteristics, and provides energy saving. By combining elemental technology and renewable energy utilization technology, a 'zero emission house' can be provided.

Afterwards, the environmental information collection module collects environmental information about 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, solar radiation, and site characteristics.

Climate elements refer to basic physical quantities that represent climate, such as temperature, humidity, precipitation, clouds, and wind. Various climate elements are complexly related to each other and exchange energy. In this way, various climate factors are intertwined to maintain the current climate and weather conditions. Meanwhile, factors that affect the spatiotemporal distribution of these climate elements are called climate factors. Climate factors include the intensity of solar radiation and latitude changes, distribution of oceans and continents, ocean currents, locations of high and low pressures, mountains, and altitude above sea level. etc. are representative examples.

Figure 7 illustrates a climate analysis method using 'Autodesk Weather Tool' software. After analyzing the climate of each region using a climate analysis program, it is applied to the plan to lay the foundation for a natural design. The climate of each region can be analyzed statistically using 20 years of data, and created directly using climate data. In addition, using data from US and D.O.E., it is possible to analyze Comfort Zone (annual-weekly-daily), temperature, humidity, sunlight, solar radiation, etc. of each data.

And, insolation refers to the amount of solar radiation energy (insolation) coming from the sun that reaches the ground. The amount of solar radiation can be determined by measuring the amount of energy radiated per minute in an area of 1 square centimeter (㎠) placed at right angles to the sun's rays. On the other hand, solar radiation refers to the amount of sunlight shining on the surface of a certain object or the ground and is distinguished from the solar radiation. For example, if a tall building is too close, it will cast a shadow and prevent you from getting enough sunlight.

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

Since buildings continue to be influenced by the surrounding environment, this environmental information must be reflected and taken into account when analyzing the load and energy consumption characteristics of the building.

At this time, environmental information collection can use various sensor equipment and publicly available statistical data, and the environmental information collected in this way may be stored in the environmental information collection module using a database. Then, the building appearance determination module By simulating the environmental information, the optimal orientation of the building that can minimize the heating and cooling load is determined, and the energy load due to solar radiation is predicted to determine the optimal shape of the building to achieve the carbon reduction target (step S3).

Cooling and heating load refers to the amount of heat required to continuously maintain comfortable conditions while cooling and heating the building. Calculating this cooling and heating load can be said to be the most basic and most important in the process of cooling and heating design. Therefore, it is desirable to design buildings to minimize such cooling and heating loads. The amount of sunlight varies depending on the altitude of the sun over time, and it is generally known that buildings facing south are traditionally more sunny.

By simulating the environmental information, the optimal orientation of the building that can minimize heating and cooling loads can be determined. Depending on the latitude, altitude, and position of the sun in each region, the azimuth angle that can increase energy efficiency the most can be measured. And, although it is difficult to match the architectural plan exactly, various plans are possible due to the characteristics of the region. The optimal direction reflecting energy efficiency can be analyzed, and an example of the analysis of the optimal location to reduce the cooling and heating load based on the average solar radiation and solar radiation amount based on the 'Autodesk Weather Tool' is shown in Figure 8.

In addition, by predicting the energy load due to solar radiation, the optimal shape of the building can be determined to achieve the carbon reduction target. Figure 9 shows simulation results predicting the energy load due to solar radiation using 'Autodesk Ecotect 2011' software. By predicting the energy load by measuring solar radiation received on the exterior of the building, the effective shape of the building can be determined, which can be an important indicator in building design.

In addition, the building envelope design module predicts the energy load due to solar radiation, determines the building envelope to maximize the energy load, analyzes the amount of sunlight flowing into the room, and simulates the useful illuminance to minimize lighting energy. By measuring the airflow inside and outside the building, the location and size of the windows are designed to facilitate airflow circulation and ventilation (step S4).

By predicting the energy load due to solar radiation, the building envelope can be determined to maximize the energy load to achieve the carbon reduction target. Figure 10 shows simulation results predicting the energy load due to solar radiation using 'Autodesk Ecotect 2011' software. By predicting the energy load by measuring solar radiation received on the exterior of the building, the effective building envelope can be determined, which can be an important indicator in building design.

In addition, the position and size of the window can be designed to minimize lighting energy by analyzing the amount of sunlight flowing into the room and simulating the useful illuminance. Figure 11 shows the results of solar radiation analysis simulation using 'Autodesk Ecotect 2011' software. Referring to FIG. 11, the position and size of the window can be designed through simulation of daylight distribution and useful illuminance required for the interior. As a step to measure the daylight rate, which measures the amount of sunlight entering the room, and to match the useful illuminance inside, the position and size of the window can be determined and simulation measurements can be made for the user's visual comfort and lighting energy savings.

Also, by measuring the airflow inside and outside the building, the position and size of windows can be designed to ensure smooth airflow circulation and ventilation. By analyzing the amount of sunlight and simulating the useful illuminance, the positions and sizes of windows designed to minimize lighting energy are recalibrated or complemented. Figures 12 and 13 show air flow analysis simulation results using 'Winair 4 / Flovent' software. The flow of air can be defined through direction, intensity, and temperature. By measuring the flow of air (direction/intensity/temperature) inside and outside the building, the layout of the building and each room, and the location and size of the windows can be determined. , This can help determine the overall shape of the building. In particular, referring to FIG. 13, through this simulation of air flow, it is possible to evaluate not only the units of individual buildings, but also the arrangement of a complex of buildings.

Finally, the building interior wall design module simulates the environmental information, measures the flow of airflow inside and outside the building, determines the arrangement of the building's interior walls to ensure smooth airflow circulation and ventilation, and predicts the building's cooling and heating energy load to calculate the carbon dioxide. Design the material of the building's interior walls to achieve the reduction target (step S5).

By simulating the environmental information and measuring the flow of airflow inside and outside the building, the arrangement of the building's inner walls can be determined to ensure smooth airflow circulation and ventilation, which shares the design method and simulation of the location and size of the window. Therefore, the air flow analysis simulation results using 'Winair 4 / Flovent' software in Figures 12 and 13 can be used to determine the arrangement of the inner wall. In addition, the carbon reduction target can be set by predicting the cooling and heating energy load of the building. The material of the interior walls of a building can be designed to achieve this. After analyzing the local climate and setting the requirements for external conditions, and setting internal conditions appropriate for each type of building, the energy usage of the building can be measured and the internal annual temperature evaluation can be predicted. Figure 14 shows the external conditions and internal temperature. It indicates conditions, and these internal conditions must be given differently depending on the purpose, number of users, and location of each building. The heating and cooling energy load of a building according to these major structural members can be predicted and the energy consumption according to the material can be measured, and through this, the material of the building's interior walls can be designed.

Figure 15 shows the temperature distribution simulation results using 'IES/VE' or 'Autodesk Ecotect'. Through this, the annual temperature of each room can be measured according to the temperature of the comfort zone and the resulting comfort can be measured, and the internal and external temperature measurements of each room during a specific period can be predicted and applied in the design process.

Figure 16 shows the results of energy usage simulation using 'IES/VE' or 'Autodesk Ecotect'. It is possible to predict the cooling and heating energy load of a building according to the main structural members and measure the energy usage according to the material, and these results can be used to help determine the material of the interior walls. In addition, in order to measure the energy load, it must match the materials of the exterior wall, interior wall, roof, and floor of the building, and this must be changed according to the use of the building. To facilitate this, it can be verified through simulation.

Through these steps, the present invention reflects energy efficiency from the design stage of the building to reduce carbon. Specifically, it simulates environmental information such as climate factors, solar radiation, and site characteristics to provide a highly energy-efficient building design. By combining energy-saving technology and renewable energy utilization technology, a 'zero emission house' can be provided.

And, in a preferred embodiment of the present invention, the method of designing a building with high energy efficiency further includes a step (S5') of introducing a renewable energy utilization system to achieve the carbon reduction target after step S4. It can be included.

Figure 2 is a diagram showing the configuration of a building design system with high energy efficiency according to a preferred embodiment of the present invention, and shows a renewable energy utilization system.

Carbon reduction can be achieved through energy savings by designing a building that applies the energy-saving element technologies reviewed above, but higher energy efficiency can be achieved by utilizing renewable energy utilization technologies. Therefore, the design method of the present invention can additionally introduce a renewable energy utilization system to achieve the carbon reduction target.

This 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 during building operation. The types of renewable energy utilization systems are not particularly limited, but include solar heating systems, solar power generation systems, photovoltaic power generation systems, and vertical axis wind turbine power generation systems.

In addition, in a preferred embodiment of the present invention, the method of designing a building with high energy efficiency includes an energy efficiency evaluation module evaluating the energy efficiency of the designed building and comparing it to the carbon reduction target for S3, S4, and S5. It may further include a step (S6) of determining whether to re-perform the step.

Figure 3 is a diagram showing the configuration of a building design system with high energy efficiency according to a preferred embodiment of the present invention, and shows an energy efficiency evaluation module.

The energy efficiency evaluation module evaluates the energy efficiency of the designed building. This is to prepare a way to control the amount of carbon generated and reduced in the house at the initial stage of measurement and design, and also measures various energy loads to determine a portion of the energy efficiency. This is a plan to control the energy load not only in the building, but in the entire building.

Figure 17 shows the results of evaluating carbon emissions using 'Autodesk Green Building Studio', and Figure 18 presents examples of various energy load measurements.

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, the building design is finalized through several additional follow-up tasks. However, if the energy efficiency of the designed building does not meet the carbon reduction target, steps S3, S4, and S5 can be re-performed through feedback. In addition, the above renewable energy utilization system can be selectively introduced (see Figure 4). In addition, the present invention includes a carbon reduction target setting module for setting a carbon reduction target value; An environmental information collection module that collects environmental information on climate factors, solar radiation, and site characteristics; A building exterior determination module that simulates the environmental information to determine the optimal orientation of the building to minimize heating and cooling load, predicts the energy load due to solar radiation, and determines the optimal shape of the building to achieve the carbon reduction target; By predicting the energy load due to solar radiation, the building envelope is determined to maximize the energy load, the amount of sunlight flowing into the room is analyzed, the useful illuminance is simulated to minimize lighting energy, and the airflow inside and outside the building is controlled.

It is largely divided into a basic approach stage and an analysis development stage, and can optionally include an active design plan based on a passive design plan.

The design process leading to is carried out corresponding to the environmental simulation.

Hereinafter, we will examine in more detail with reference to specific design drawings according to the design method of a preferred embodiment of the present invention.

19 and 20 show detailed design drawings according to the design method of a preferred embodiment of the present invention. Referring to Figure 19, part of the roof is open, allowing natural lighting and natural ventilation into the living room. A greenhouse air circulation system was adopted in the greenhouse at the front, and natural lighting was available to increase energy efficiency. A solar power generation system is installed on the roof to increase energy efficiency by using a renewable energy system. Referring to Figure 20, a cross-ventilation system using the veranda space is in operation, and is equipped with a bio-ethanol generating device and an eco-friendly food dehydrator. And, referring to Figure 21, it can be seen that the performance of the designed building has been verified through the use of 30 energy saving techniques.

The building designed according to the present invention applies passive design to construct a spatial structure that adapts to the local climate and a design that reduces energy load by using only eco-friendly building materials, and the scent of the building, the layout of each room, and the design of the openings. , window types, material selection, etc. were optimized.

Figure 22 shows the heating system, dividing the building into four compartments, using eco-friendly materials with a three-dimensional structure for energy saving effects, simulation for optimal design, and dividing the layers of each room into heating zones and non-heating zones. It was planned as a district. According to this plan, it is necessary to select openings, windows, and materials accordingly. Figure 23 shows the lighting characteristics for natural light inflow into the building designed according to the present invention. Indirect lighting was taken into consideration to increase lighting efficiency, and lighting according to seasonal changes was also taken into consideration.

Figure 24 shows the ventilation characteristics of the building designed according to the present invention. By using monitor windows, ventilation efficiency was increased due to the Bernoulli effect, and cross-ventilation in the north-south direction was possible.

Figure 25 shows internal airflow circulation and internal cross-ventilation characteristics. In winter, internal airflow circulation is possible through the balcony, and in summer, internal cross-ventilation is possible through the opening design.

Figure 26 shows the shading and insulation characteristics of the balcony blind of the present invention. Balcony blinds enable both shading and insulation effects at the same time.

Referring to Figure 34, it can be seen that an energy saving effect of 39.6% can be achieved by using eco-friendly building members.

Because designing existing eco-friendly buildings requires specialized decision-making in the facility field such as building materials, heating and cooling load, and climate factors, the energy performance of the building can be evaluated only after the facility design is completed in order to apply eco-friendly factors. These energy performance analysis tools provide energy load calculations using BIM (Building Information Modeling) created in the early stages of architectural design, so they go through a feedback process until the optimal plan is obtained. In addition, various architectural simulation tools that can be applied to each design element can be used and applied to actual plans. There are many simulation tools available to perform such simulations, but the easy-to-use simulation tools are summarized in Table 1 below.
