Ecological design is one of the most important areas of modern architecture. The buildings constructed in this way are different, there are no typical solutions in the industry, and each project is unique. Today we will tell you about a new and, to a certain extent, unique technology in the Ukrainian market of energy solutions, called Green BIM.

Green BIM is a symbiosis of two seemingly unlimited areas: the BIM (Building Information Modeling) and the Green Building Industry (BIM) strategy. After all, the introduction of BIM-technologies aims to reduce the cost and duration of the project, while adherence to the basic principles of green construction, as a rule, leads to an increase in the cost and duration of work. But the development of information and energy technologies allowed us to combine both directions to maximize the cost of construction and operation of the facility and increase the level of comfort.

Implementation of the Green BIM concept involves several main steps, among which:

· analysis of climatic conditions;

· Modelling of engineering systems;

· Designing the concept of building use.

Designing for the Green BIM concept should take into account many factors. We will tell you about them in detail.

The place of location

This item is very important for the construction of an energy efficient home. The natural and climatic conditions in the location and the way in which they will affect the building should be taken into account. It also includes the choice of optimal orientation towards the world, analysis of sunlight, determination of the potential of using wind turbines.

The form.

This item is directly related to the previous one because the most optimal form of construction depends on the geographical and climatic conditions in the location. For example, if there are strong winds in the area, it makes sense to give preference to the streamlined form.

Terms of use of the building.

It is important to understand the conditions of future operation of the house, the number of people who will live in it, or stay on it regularly, and so on. The design stage should take into account the typical operating schedule (the building and equipment itself). It can be a residential house, which is used mainly in the morning and evening, and in the daytime is almost empty; or an office that works according to a certain schedule and closes at night.

The problem of temperature preservation.

The building should be designed in such a way that the heat loss is minimal.

The materials

The materials should be environmentally friendly, and it is desirable that they are manufactured and procured as close as possible to the construction site in order to reduce transportation costs.

Zoning of placements

It is being implemented to increase the efficiency of their use.

The engineering systems.

The use of the most modern, reliable and rational in terms of utilizing the resources of engineering systems (ventilation, heating, water supply, air conditioning, etc.) is foreseen.

The renewable energy sources.

The Green BIM concept involves the use of renewable energy sources, although this is not always possible.

Part of the above problems can be solved by the architect himself (for example, the form of a building or the zoning of the premises), while for others, the involvement of automated simulation systems is required. After that, you can analyze the energy efficiency of the building, calculate energy consumption and cost at all stages of the construction. On the basis of the information model, a lot of tests and simulations of the operation of the building are carried out under different conditions, which allows a better evaluation of the project in terms of energy efficiency.

With the correct use of the strategy, Green BIM allows you to get at the same time several effective projects of one building and choose among them the most suitable option.

The era of massive and cheap construction is mentioned today, like a ghost. Except for the problems with the organization of everyday life, “budget” construction objects are not able to provide anything else. A completely different thing is green construction. Karno Energy tells you about the “green sector” of the construction industry.

Green construction – the construction of public and industrial objects, which harmonize as much as possible with the environment and do not harm the environment. Green building objects are energy-efficient and allow to use the innovative technologies with a focus on improving the ecological state of the region.

Each building of green construction is assigned a level of compliance with green standards. The most common evaluation system is LEED.

The rating system of green construction evaluation

LEED (Leadership in Energy and Environmental Design) – a guide to energy and environmental design. Developed and adopted in 1998 by the American Council for Green Building issues.

The LEED evaluation system can objectively analyze the state of these structures:

· Residential complexes (new construction);

· Schools

· Hospitals;

· Trading institutions;

· Production facilities.

LEED evaluates not only individual buildings but also determines the level of compliance with the green standards of the area where they are located. LEED also assesses the interior of the apartments and the exterior design.

The rating scale has 100 points. LEED system is capable of accrediting the building for four levels.

^standard certificate (40-49 points);

· silver certificate (50-59 points);

· gold certificate (60-79 points);

· platinum certificate (from 80 points and above).

The following areas of analysis are taken into account: efficiency of use of water and energy resources, air purity, general ecology of the region, building materials and technologies, architecture and influence of structures on the socio-economic development of the region (regional priority).

Other evaluation systems

1. BREEAM (BRE Environmental Assessment Method) – the method of environmental assessment of the efficiency of structures. The evaluation system was developed by a British non-commercial company in 1990. To date, the BREEAM system has analyzed more than 1.2 million buildings, including 1 million – construction of new construction.

The assessment is carried out according to the 5-point system. The analysis takes into account the factors of influence on neighbouring objects and the environment of the entire region. BREEAM can be adapted for an objective assessment of buildings at any corner of the Earth.

2. Energy Star – An International Standard for Energy Efficiency. The Energy Star rating is conducted separately from LEED and BREEAM. This standard analyzes energy-efficient building technologies. The Energy Star certificate is awarded to buildings that have reduced the load on standard electricity supply and heat supply systems by 20-30%. It is understood that the load was reduced due to the transition to alternative sources of electric and thermal energy.

In addition, the Energy Star sign is also found on many household appliances, industrial equipment, and the like. The Energy Star logo says that the technology uses energy-efficient technologies.

What does a certificate of compliance with the norm of green construction give?

Almost all buildings, which have a confirmation of compliance with the green standards, receive permission to introduce into the structure of engineering systems of innovative technologies. That is the building marked “green building” has the right to use alternative energy sources that do not harm the environment. In addition, compliance with green standards automatically increases the level of comfort of apartments.
