BIM Objects represent a geometrically-effective combination of the different information about the product’s functionality. The accurately presented geometrical characteristics allow placing a BIM Object in the right position of the project. BIM technology can also enable the precise visualization and evaluation of the product.
With BIM you can compare every aspect and property of the comparable items. It’s important or the modern construction project in the UK to be distinguished by the acute behavioral characteristics even at the virtual level. BIM creates opportunities to build a recognizable structure using the objects of any shape. We compile the BIM elements suitable for any UK construction project.
How we create BIM Objects?
We produce the BIM objects with the highest consistency, so you can be sure it will fit into the BIM structure as expected. Every dimension of a BIM Object and its appearance is as close to the real UK environment as possible. All our BIM Objects conform to the actual physical and geometric properties stated in the certification.
We can produce Revit families with Level of Detalisation (LOD) 300, 350 and 400. Depending on the requirements of your project we can make Revit families parametrical, add 2D symbols or fill BIM objects with necessary parameters. Also, the KarnoEnergy team will decrease the Revit family size to a minimum to make your model faster and work with better results.
Every benefit of the modern building information modeling (BIM) is at your disposal by the click of a mouse. You can quickly search through our BIM catalog to find samples of our work.
How to use BIM Objects?
Via a user-friendly interface, you can save the necessary elements to the BIM Library. The datum of each BIM Object is presented in a well-structured specification. You can modify your BIM objects to meet the requirements of the manufacturer \ project owner. The selection of BIM objects is constantly updated so you and your colleagues can work harmoniously. Reduce the cost of the construction and save your time while providing a benefit to the design.
When we speak about BIM or building information modeling, BIM definition may be hard to embrace at a go. The modern strategy of construction design tries to integrate each element into a consistent toolkit using BIM.
This Building Information Model covers the period from the project conception to the final demolition of the building. The undeniable advantage of BIM technology is interconnectedness. When you change any parameter of a BIM model, every associated object, drawing or visualizations also changes automatically. In fact, BIM creates a unified environment with access for professionals from a variety of fields.
BIM tools are used not only by the development team but also by the contractors and sub-contractors. In this way, BIM reduces the potential loss of information and provides valuable insights to the project owners. Also, the BIM meaning is undeniable in the matters of cost recovery. The annual BIM report consistently shows a high return on investment. Thus, BIM is an integral part of construction engineering development in the future.
What is a BIM model?
In a practical sense, a BIM model is structured information about a building suitable for digital processing. Building information modeling (BIM) is used within the framework of an object’s life cycle. Moreover, BIM brings together all the data available, allowing to use it for solving a variety of tasks. It becomes much easier to make specific constructive decisions using BIM.
As BIM provides a link to each level of the project, one can estimate the potential functional performance. Concerning the inventory and logistics management, the advantages of BIM should not be underestimated either. With BIM cost estimating and equipment ordering won’t take a lot of effort.
The result of BIM modeling is always dynamic, allowing making changes at any time. Although this significantly differs from the traditional design method, this is also why BIM projects are so promising. Nowadays the buildings’ utilization often changes repeatedly in a short time. That’s why the alterations detection and making some possible improvement is crucial.
How can Building Information Modelling (BIM) help you?
The capabilities of BIM projects allow designing or reconstructing a building anytime. It’s also getting easier to manage it as an object of commercial activity. Modern building information modeling lets to transfer the generalized and structured information for further use.
Nowadays BIM software takes over the processing of constructive information. As its volume is huge for a single project, it’s extremely difficult for a person to cope with. The collection and complex processing of the entire data volume results in a BIM model. The developed model is saturated with the information much more than the usual drawing. BIM technology is a logical stage of the standard design methods’ evolution, bringing them to the modern level.
The diversity of BIM objects
Usually speaking a BIM object means any infrastructure object. It embraces a variety of engineering networks (water, electricity, communications), railways, bridges, tunnels, etc. With BIM you can create anything, this approach is universal. A 308-meter «One Island East» skyscraper, built in Hong Kong in 2008 is a great example of this technology’s application.
The benefits of the BIM process over the classic method
Working with building information modeling in the UK one can review the model in different ways. Some still prefer to work with the familiar 2D plans and profiles. But there is no denying that the new generation tends to work on the BIM projects in 3D. Thus, the BIM process allows considering and processing the information in a variety of ways.
It builds on the traditional design methods, incorporates and enhances them. Any aspect of the building included in the model is an interconnected element of the overall structure. With this unity, to carry out calculations and analysis becomes much faster and easier.
What is BIM in construction?
Of course, fundamental decisions on design, as before, rest in the hands of people. But BIM construction performs its technical function of finding, processing and analyzing the necessary data. BIM technology is useful for finding the inconsistencies arising when the object is designed by many different specialists.
The discrepancies’ detection is a result of the continuous processing of the information submitted into a collaborative model. It becomes clear that the use of BIM in the construction sphere helps to avoid critical errors. And, of course, it allows reducing the costs significantly. This aspect underlies in the BIM level 2 development strategy. Reduction of the delivery and operational costs, along with the risk minimization characterizes this tendency the most.
What does BIM stand for?
An all-embracing approach to the object’s exploitation. It involves the collection and integrated processing of the architectural, economic and other data in the design process. The building (structure) and everything that has to do with it is considered as a single indivisible unity.
What is BIM level 2?
A state-initiated by the methodology aimed on reducing the cost of the public sector infrastructure using BIM technology. The key point is the use of the collaborative 3D BIM models.
What is BIM in construction?
The use of an information model aimed at solving any problems arising during the entire life cycle of the object. It’s aimed at preventing any design errors, reducing the cost of building’s exploitation.
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.
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.
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 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);
· 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.
Is it necessary to reuse wastewater: the experience of other countries
Savings of household resources – a rather difficult task. Particularly acute is the need to introduce a policy of “adjusting costs” for water supply. In this material, we will consider in detail the problem of reuse of wastewater. What is this practice, how much it allows you to save and as expedient as possible?
The process of regeneration
Regeneration of water – cleaning and refurbishment of spent liquid and precipitation. Purification involves the transformation of the sewage runoff into the water supply. The spent liquid is subject to the following stages of treatment:
· removal of mechanical particles;
· return of transparency;
The practice of reuse of water came to us from arid countries, where a litre of drinking water costs more than a litre of fuel. It seems strange for many compatriots to drink regenerated water (purified sewage liquid), but in most arid countries this is the only opportunity to offset the shortage of water resources. Regeneration can return more than 50% of wastewater, saving lives to hundreds of millions of people.
However, even developed countries that do not have an obvious shortage of water resources, today also pay attention to the process of regeneration of wastewater. The sewage can not only be drunk but also used for technical purposes. Regeneration to the state of technical water is much cheaper than the state of drinking.
Technical water is a liquid that can not be used in the food industry. You can not drink or use it for cooking. But it is great for watering the ground, washing and wash off in the toilet.
Regeneration of water is not necessarily a global event, as in central urban or district treatment plants. There are compact systems for the recycling of household or industrial water, which, with the permission of the city authorities, are installed at a specific facility.
In many countries of Europe, private systems for the regeneration of atmospheric precipitation and drainage fluids from the soil have become widespread. Buildings of this type allow reducing the load on the city collector system during the storms and spring floods.
City stations use budget technologies for water preparation, which require large-scale and long-time treatment facilities:
Object (private) treatment facilities are compact filtering stations, which instead of separation, defending and other measures listed above apply the following technologies:
· membrane cleaning;
· reverse osmosis
· multi-barrier filtration.
The degree of filtration in regeneration systems depends entirely on the requirements of consumers. That is, cleaning the waste liquid for food needs and watering the land has different degrees.
The role of technical water is suitable for the liquid with the presence of sodium salt, phosphates and other aggressive solutions. Such water is used for subsoil watering. That is, the technical water does not process the crown of bushes and trees. The technical fluid is fed immediately to the root system. Water for nutritional needs is subject to more qualitative cleaning.
In countries that do not have a clear shortage of drinking water, sewage is regenerated only to the state of the technical fluid.
In this material, we will tell you how to make your home efficient and functional. To do this, you do not have to invent the wheel. Smart House – modern technologies that make housing the most rational, efficient and functional as possible.
Smart House – a software and hardware complex that allows you economically and, most importantly, distribute power supply to the power grid safely. The main goal is to increase the “intelligence” of household appliances. That is, the equipment for a “smart house” is composed of elements of automatic control, which makes human life more comfortable and safe.
Functional Smart House allows:
· To reduce the load on the power grid (up to 15-20%);
· To increase the reliability of the main systems (security, climatic system);
· To simplify management of equipment;
· To make life more comfortable.
Smart House systems are unified. The software and hardware complex of a smart house in most cases are ready to use the product. Professionals can only pick up the equipment for the needs of a specific customer and set up the system.
Functional Smart House allows you to save up to 15-20% of electricity. At the same time, home furnishing becomes more reliable, safe and functional.
What is Smart House System consist of?
The hardware and software of a smart home require a separate room (multi-room) or a dedicated technological line, where central automation elements and a viewing display will be installed.
Smart House consists of the following systems:
· security (security, video surveillance, access restriction);
· communication (telephony, local computer network);
· entertainment system;
· heating / air conditioning / ventilation;
· distribution of power supply to the power grid;
· control panel.
All functional systems of Smart House are integrated into a single network. The equipment of a reasonable home is composed of elements of automation. That is, lighting, heating, air conditioning and other systems are connected with the control and executive logic unit (artificial intelligence).
Manage your home equipment from one place (multi-room). In addition, many systems of Smart House have a universal control panel. For example, buttons of a keychain are programmed for this or that technique. It is important that the gadget has an infrared port or a wireless module (Wi-Fi, Bluetooth).
Many systems of Smart Houseintegrate with computer networks. If the local network has Internet access, then smart home systems can be managed through remote access using a smartphone.
How does Smart Housework?
All Smart House functional systems are conventionally divided into three categories:
· high priority;
· average priority;
· low priority
A high priority is the security system. The security complex operates around the clock, so the security system works through the battery pack. Depending on the chosen scheme of a Smart House, the batteries replenish the resource either from a domestic network or from a source of alternative energy (solar cell or air engine).
Systems with medium and low priority are switched on, taking into account the expediency and overall load on the grid. For example, if the irrigation system is turned on, then only one of the three conditioners in the house is left in the house. After completing the irrigation, the air conditioning is switched on at full capacity (depending on the chosen home cooling program).
Over the past few years, in the construction projects of an international level, there has been a real revolution that BIM- technology has implemented. Therefore, native builders who deal with international standards or wish to take part in international construction projects will definitely have to establish construction on the basis of BIM.
BIM (Building Information Model) is a building information model. The technology goes beyond the classical systems of automated design (CAD). It is the basis or foundation for all stages of construction. If CAD opens the way to architectural design work in individual construction projects, then BIM combines all construction: from designing engineering systems to purchasing materials and even service of the facility after its commissioning
BIM design of the main engineering systems
BIM-technology allows you to create projects of dependent on each other engineering systems. For example, air conditioning specialists have developed and integrated a climate system scheme into a common BIM project. The building program displays a general three-dimensional model of the object and shows how it will interact with neighbouring engineering systems. That is, it is possible to immediately identify in which places there will be conflicts between communication, where they will be crossed and how safe they will be for each other.
Unlike classical CAD, BIM technology provides information on the technological features of the engineering system (circuit diagram, name and characteristics of equipment, the possibility of modernization, etc.), and the process of creating communications (technological map of construction), and the dynamics of the interaction of design systems between themselves and with the environment.
It should be noted that even if the planned project engineering system will make unscheduled changes then all developers of the general construction project will know about them. For example, the engineer decided to save on the quality of air conditioners or cooling reagents and made changes before purchasing construction materials. That is, the employee wanted to put a difference from the planned and real costs of himself in his pocket. BIM platform automatically makes changes to the budget, and also proves information about “unscheduled” changes to the attention of the monitoring commission.
Advantages of BIM-technologies
· The only working platform for all project participants.
· Maximum transparency at all stages of project implementation.
· Automatical coordination of all employees in real time.
· Ability to study the project on a three-dimensional model.
· Automatic search for errors and miscalculations.
· Forecasting emergencies and finding weaknesses.
· BIM-construction allows to systematize and generalize all aspects affecting the design, construction, operation and even utilization of the controlled object.
Regulation of the sphere of BIM-construction by the authorities
In Ukraine, there is almost no interest in BIM-technologies among public organizations. BIM standards are used by several organizations involved in international construction projects.
From neighbouring Belarus only began to implement BIM-construction standards. By comparison, in the UK, BIM standards from 2011 are mandatory in the public and industrial sectors. In the US, BIM technologies are being implemented since 2003 (at present the BIM sector has 30 million square meters of housing and engineering space).
Today, no international construction project can do without a BIM platform.
Support nature – and nature will support you. In the language of modern technology, it is quite possible to translate as: “Go to green energy – and get 75% energy for free”. That is, using 25 kW of electric energy, you can receive 100 kW of thermal, which does not harm the environment and is self-restored. Karno Energy tells you about this free energy help.
Let’s start with the fact that all heat pumps are divided into two categories:
· for the private sector;
· for city objects.
In the private sector, ground-water, water-water, air-water heat pumps are used. That is, a private plot allows you to build freely the necessary communications in the soil or in the reservoir. When it comes to horizontal constructions, then 1 kW of calculated thermal power requires from 25 to 50 m2 of land/water area.
Urban facilities do not have free access to geothermal sources (water and soil). As an urban heat pump, engineering systems of air-air, air-water or power piles are used.
What efficiency of the heat pump depends on?
The efficiency is estimated by the following metrics:
· work-load during the year;
· the amount of energy received.
The greater the load and the more energy is received, the faster the technology will pay off. A well-balanced heat pump, which is used correctly, reflects its price during the first four years under operating conditions for 15-20 years before the first major overhaul.
Heat pumps with a reverse of the thermal circuit are considered to be most effective. This technique can be used throughout the year. During the winter weather season, the pump will provide the facility with warmth, and in the summer it will be cool. Load of the heat pump with reverse is 80%. Classic heat pumps (operating only in winter) provide a load of no more than 40%.
What pumps are used in Ukraine?
Heat pumps of this type are divided into horizontal and vertical. Horizontal systems are picked up to a depth of 3 m (the temperature at this depth is +8 ° C throughout the year). Structures for water are immersed at a depth of 2 m.
For vertical systems it is necessary to drill the soil to a depth of 30-250 m, the temperature of the medium can reach +12 ° C. The wider the hole, the smaller the depth is used. For a well of 30-70 m, it is better to use a hole for 280-300 mm. Vertical heat pumps for water are almost not used today.
Soil/water pumps can work independently of the outside air temperature. The technology will be stable in producing heat even at -40 ° C in the street
Techniques of this type can be installed anywhere, even on the roof of a multistory dwelling house. The air heat pump takes at least the useful area. The equipment is much cheaper than ground/water analogues, but as well as they can work year-round, providing heat in the winter, and coolness in the summer.
But air heat pumps have several significant disadvantages: an increased level of sound noise and temperature constraints (the air heat pump does not work at an air temperature below -25 ° C). When it is frost, you will have to use a standby heating system, such as a warm floor or classic radiator heating.
Taking into account the high level of efficiency, affordable price and easy installation, many homeowners prefer the air heat pump itself.
