Classification of office buildings. Types of offices: cabinet, open space, combined

In Moscow and the regions of Russia today, office space located in business centers is in great demand. But today, despite the abundance of offers on the commercial real estate market, truly high-quality Business centers are in short supply. Convenience, prestige and customer trust largely depend on the class of the premises. There is a list of requirements for business centers, depending on the availability of which one or another class is assigned.

All office premises are usually classified into categories. The most common classifications of office premises are class “A”, class “B” and class “C”. The assignment of a class depends on the location, year of construction of the building, its design features, and layout. Engineering systems (air conditioning, ventilation, telecommunications, elevators), parking and security. If you are planning to rent an office, then you should know this classification.

Class A business center.
Offices of category “A” are the best offer on the commercial real estate market, but the price of such offices is the highest.
Such business centers are located in new buildings or in buildings after major renovation and reconstruction in the city center, which makes them the most expensive. Class A offices have an original design of premises, modern equipment, a VIP room, and fiber-optic telecommunications. A security service and an access control and video surveillance system are required. Be sure to be in the immediate vicinity - metro stations, public transport stops, car parks, cafes. Large trade and administrative centers are usually located nearby.

The facades and interior decoration are made of high-quality modern materials, often based on individual projects and using interesting architectural solutions. The internal layout, as a rule, can be easily changed at the request of the tenant or owner. Such centers also have an uninterruptible power supply system, are equipped with the most modern engineering systems, central air conditioning or climate control.

Class A business centers must have their own underground parking and surface parking. There are also cafes and canteens for employees, conference rooms and sports clubs.

Large firms and international companies become tenants of office space of this class.

Business center class B.
Class B premises are somewhat inferior to category A. These are economy class premises, and their rental costs are much lower. They are located in modern or converted administrative buildings. Sometimes located in business centers with 5 years of operation. The building parameters are identical to Segment A real estate, but the range of services is narrower. Thus, surface parking is provided, but there is no underground parking. Class “B” offices are not equipped at the highest level, ventilation systems and engineering systems are of a lower class.

Business center class C.
Segment “C” is of interest to enterprises and administrative organizations for office activities. Initially, such premises were not designed for such use. The infrastructure generally meets the minimum requirements. There is often no air conditioning system. Most of the buildings are in need of renovation and are considered outdated, but the presence of main communications allows work activities to take place. Services include telephone communication, Internet, ventilation system, toilet located in the corridor, heating system and dining room, parking is not provided. They are often located in residential areas. Class “C” office space is rented by small organizations.

In addition to class A, class B and class C, there is also class D, which is typical mainly for regions. Tenants in such a Business Center receive nothing except the premises themselves, which are often in need of repairs. The lack of infrastructure and the old-fashioned office-corridor layout create significant inconvenience for both office owners and their visitors.

This classification will help you adequately evaluate the premises if you need to sell an office, buy an office or rent office space.

In international practice, several classifications of office real estate are used, however, the system developed by BOMA (Building Owners and Managers Accociation) is considered the most used. Business centers are classified according to categories “A”, “B” and “C”.

Office premises of class “A” are the most prestigious and of high quality; the characteristics of class “C”, in turn, are far from modern requirements. Assignment to a particular class is to a certain extent subjective and is made taking into account compliance with certain characteristics:

1. Location.
2. Building type.
3. The novelty of the building.
4. Building maintenance systems, security system.
5. Solutions in the planning, decoration and construction of the building.
6. Engineering systems, air conditioning and ventilation systems.
7. Telecommunication systems.
8. Parking.
9. The building is equipped with elevators.
10. Infrastructure.

In Russia, a unified classification of office premises has not yet been approved. There are many variations of systems used on the market, but they are all based on similar principles.

The most famous classifications are:

1. Classification of the chief analyst of the Russian Guild of Realtors G.M. Stubble.
2. Classifications of the Moscow Research Forum, developed in 2003 and updated in 2006 and 2013.
3. Classification of the St. Petersburg Research Forum 2008

Many appraisal companies use a system similar to "ABC". In Russian realities, some companies add a special category “D”, which is due to the fact that many buildings date back to the Soviet era, have not been reconstructed and do not even meet the requirements of category “C”.

In accordance with the tightening requirements at the Moscow Research Forum in 2006, the 2003 classification was changed. The new structure divides modern office buildings into three types: “A”, “B+” and “B-”. Buildings that do not meet the specified criteria are classified as classes “C” and below. In 2013, an important innovation was the “Certification” item, that is, the compliance of office centers with international energy efficiency standards: LEED and BREEAM.

The second classification system involves dividing class “A” into additional categories:"A1", "A2", "A3" and is more detailed. The companies Noble Gibbons and Colliers International use it in their practice. The division into subclasses “A+”, “A” and “A-” is similar.

Class "A"

Class A business centers, which are the optimal solution for office premises, are located in new complexes with competent planning, a high level of construction and finishing, automated life support systems, equipped with security, communications and communication systems. Such offices are mainly built in the city center or in prestigious areas with a large number of transport links.

The tenants of premises in high-class business centers are large companies and branches of foreign companies. Class “A” fully meets all the criteria of a modern building, which include:

1. Availability of a central building management system.
2. Availability of a modern fire safety system.
3. The ceiling height is at least 2.7 m.
4. High-quality finishing materials for common areas and facades.
5. The waiting time for elevators is no more than 30 seconds.
6. The depth of the floor from the window to the “core” does not exceed 10 m.
7. Availability of an effectively organized reception area, conference rooms, spacious food and recreation areas.
8. Designer renovation.
9. Multi-level ground or underground parking with an entrance to the business center.

For class “A”, division into subclasses is practiced: “A1”, “A2”, “A3”, which have no fundamental differences among themselves and are used to define the building in more detail.

Subclass "A1"

This subclass is characterized by:

"A2"

It has less stringent requirements for the location of the building, and can also be a completely reconstructed building of relatively recent construction. Characteristics are close to class “A1”, but allow minor deviations according to secondary parameters.

"A3"

Can be assigned to a completely reconstructed building 20-30 years old. Relatively inefficient layouts and inferior central air conditioning systems are acceptable.

There may be some deterioration in relation to the “A2” subclass, for example, the location of the office center is not in the central, but in a more remote but prestigious area.

"IN"

Economy class offices, as class B office space is often called., often have no fundamental differences from a class “A” office. Unlike class “A”, which refers to representative premises, commercial real estate of class “B” refers to work premises. Large companies locate personnel other than top management in such offices. Tenants are small organizations and companies.

Such premises are characterized by:

"WITH"

Class “C” offices are predominantly located in Soviet-era buildings repurposed for office needs: research institutes, institutes, and plant managements.

A building of this type is often characterized by a complete lack of central air conditioning, unprofessional management, and lack of equipped parking.

The renovation was carried out using cheap materials, but there are problems with electrical voltage and infrastructure. Main characteristics of class “C” office premises:

1. Location on the outskirts of the city, inconvenient access to the building.
2. Service life exceeds 10 years.
3. Standard renovation, corridor system.
4. Outdated design, inefficient layout.

"D"

Real estate objects classified as "D" class do not meet the requirements of a modern facility office real estate. Offices of this class are characterized by outdated engineering solutions, wooden floors, and lack of life support services. They are located outside the city, in converted warehouses and production facilities, and in residential buildings.

Class “D” is characterized by:

1. The condition of the building requires major repairs.
2. Corridor system, location in basements and semi-basements, lack of quality planning.
3. The parking is spontaneous and unguarded.
4. Lack of building maintenance and management infrastructure.

Range of real estate prices for offices

Office real estate prices depend on many factors, the main ones being distance from the center and compliance with one or another category. The average rental rate for a class A office in 2018 in Moscow is RUB 25,500. per sq.m. per year, a “B+” class office can be rented for an average of 16,000 rubles/sq.m. per year, and sq.m. in a class “B-” office it will cost 14,500 rubles. in year. Office rent in the lower category is, on average, 9,000 rubles/sq.m. in year.

The need for a correct assessment determines the importance of using and constantly updating the most convenient and complete classification for all market participants. Clear criteria provide a clear picture of what the tenant is willing to pay money for, and what choices and options the landlord is willing to provide.

The commercial real estate market is vast and to more easily and quickly obtain information about the main parameters, quality and condition of a building or premises, a classification of commercial real estate was created. With the help of this classification, tenants can more professionally assess the premises and their requirements for it, and developers can obtain a description of the necessary qualities of a modern office building for the further development of any facility.

Unfortunately, any classification is conditional and does not replace the need to take into account the individual characteristics of the object and other nuances. In addition, in order for the assignment of a particular property to the appropriate class to make sense, market participants must clearly understand on what basis and by what principle this is done.

Of course, it is impossible to provide a unified approach when compiling a classification, and therefore realtors, developers and consultants often create their own classifications for the market segments in which they operate, or adapt Western standards systems to Russian conditions.

Commercial real estate segmentation

Real estate can be classified according to different criteria: by purpose, by purpose of ownership, by the degree of specialization, by type of property, by the degree of readiness for use.

So, in the 90s of the last century, experts proposed the so-called “enlarged” classification of real estate. According to it, the term artificial objects was introduced. It was proposed to include special buildings and structures here:

• medical and recreational (hospitals, clinics, nursing homes and children's homes, sanatoriums, sports complexes, etc.);
• educational (kindergartens and nurseries, schools, colleges, technical schools, institutes, children's art centers, etc.);
• cultural and educational (museums, exhibition complexes, cultural and recreation parks, cultural centers and theaters, circuses, planetariums, zoos, botanical gardens, etc.);
• special buildings and structures - administrative (police, court, prosecutor's office, authorities), monuments, memorial buildings, train stations, ports, etc.

The generally accepted classification of commercial real estate, which real estate market participants try to adhere to, divides all buildings and premises into segments - office, retail and warehouse real estate. In each of the segments, classes and even subclasses are distinguished. Let’s make a reservation here: there has never been a clear understanding of the classiness of objects.

Office real estate dominates the structure of the commercial real estate market. For example, if we take the period from 2007 to 2011, then over four years it decreased by almost 12 percentage points, due to a more dynamic increase in the supply of retail and warehouse sites. According to experts, in 2012-2013. The volume of supply of office space, which does not yet cover demand, will grow at an increasing pace, although not as dynamically as the other two market segments.

In second place in the structure of the commercial real estate market is warehouse real estate. Its share has remained virtually unchanged over four years.

The retail real estate segment is the most dynamic in the structure of the commercial real estate market. The main trend of 2007-2011 became its decentralization. The high dynamics of the increase in the supply of trading floors is due to the high demand for space in shopping centers, as well as the highest capitalization rate compared to other segments of commercial real estate.

Office rooms

Until recently, the main classification of office space was to divide it into three (A, B, C) or four classes (plus D).

Class “A” objects are modern business centers built according to the design of a famous architect by a developer with an excellent reputation and certain experience in this field.

The premises in such buildings are distinguished by optimal planning solutions and high quality finishes. The building itself is equipped with the latest engineering systems; all issues related to its operation are resolved by a professional management company.

A developed infrastructure has been created for tenants; underground parking requires at least one parking space per 60 sq.m. rented areas.

For a class “B” office, it is important that it is well renovated, has 24-hour security and access control to the premises, as well as that facility management services function properly.

Class “C” unites buildings of former research institutes, hotels, educational institutions and other administrative facilities, premises on the ground floors and basements of residential buildings. As a rule, tenants decide all everyday issues, including those related to security, themselves.

Assigning a class to a business center, denoted by the combination of symbols “ABC”, means that this object by location belongs to class “A”, by the type and technical level of the building – to class “C”, by the level of the management company – to class “B” , but at the same time the integral class of the object is “C”.

If the building does not fully comply with the specified characteristics within each of the categories of a certain class, it is allowed to consider an alternative to the advantages of the building and possibly assign it to this class if the possible equivalence of the characteristics is confirmed.

Assigned classes are subject to change. As new office centers of class “A” are built and existing office centers become obsolete, they may be assigned a lower class, for example, not “B”, but “C”, or, conversely, as the building is modernized, the class of the business center may become higher.

If, along with “C”, class “D” is also distinguished, then the main difference between them lies in the quality of the premises used for offices, the presence of at least cosmetic repairs in them. Class “D” sometimes includes all basements of buildings.

New system of standards

In 2011, leading Russian consulting companies announced a new system of standards for office real estate. At the same time, only high-quality office space was taken into account, divided into three classes: “A”, “B”, “B+”.

The main difference of the new classification is in more structured evaluation criteria. All parameters are divided into groups, each of which has a certain set of mandatory and desirable characteristics. For example, for class A the object must meet the following requirements:

• availability of a central building management system;
• the ability to set individual climate conditions for each office block;
• modern fire safety systems;
• high-quality high-speed elevators from leading global manufacturers;
• two independent power sources with automatic switching or the presence of a diesel generator;
• modern security and building access control systems;
• ceiling height of at least 2.7–2.8 m;
• open floor plan;
• column spacing is at least six meters.

Here you can add the possibility of installing a full-fledged raised floor, high-quality and presentable finishing of common areas, entrance lobby and facade, good location, absence of nearby objects that have a negative impact on its image, convenient access to the building and its transport accessibility, underground parking or covered multi-level ground parking with internal passage to the house.

Buildings of class “B+” must meet at least ten mandatory and eight optional of the above requirements, and for category “B” the presence of six mandatory and eight optional parameters will be sufficient.

Retail real estate

In the segment of shopping centers in Russia, a unified classification adapted to Russian conditions has not yet been adopted. Therefore, Russian analysts prefer to use the European classification to classify shopping centers. This classification is based on:

• size of retail space;
• shopping center coverage area;
• composition of tenants;
• specificity of the goods sold.

In all cases, the type of shopping center and its specialization are determined by the composition of tenants and the size of the trading area. The development of architectural and planning solutions, as well as the leasing of shopping center space - brokerage - are carried out on the basis of the concept of the shopping center. The concept of a shopping center should reflect:

• target groups of buyers (“buyer portrait”);
• type of shopping center;
• composition of tenants (“anchors”, “mini-anchors”, accompanying ones).

According to the European classification, there are 4 types of shopping centers:

• microdistrict shopping center (Neighborhood Shopping Center);
• Community Shopping Center;
• regional center (Regional Center);
• Super Regional Center.

The Neighborhood Shopping Center sells everyday goods (food, medicine, etc.) and provides household services that are needed daily by buyers of the center's shopping area.

In the neighborhood shopping center, the “anchor” is a supermarket; other significant tenants in this center include a pharmacy and a department store. Often centers that do not include a supermarket, but are similar in total rental area to microdistrict centers, are called microdistrict shopping centers. The typical area for a microdistrict shopping center, where all its inherent functions are presented, is about 5,000 sq.m., but in principle it can range from 3,000 to 10,000 sq.m.

The typical retail area of ​​a district shopping center is approximately 15,000 sq.m., but in general it can range from 10,000 to 30,000 sq.m. It typically serves communities within a 10-20 minute drive.

The area of ​​the regional center is 40,000 square meters. m, while it can vary from 30,000 to 100,000 sq.m. Typically, such a center includes: a mall, an indoor shopping gallery with an artificial climate, and fashion goods. The number of “anchors” is two or more - for 50-70% of the area. The coverage area of ​​such a shopping center is in the range of 9-27 km.

The typical area of ​​a super regional shopping center is 80,000 sqm, but can range from 50,000 to over 200,000 sqm. Such a center is similar in size to a regional one, but has a more diverse range of goods. The main tenants are three or more full-line department stores. They can occupy 50-70% of all leasable space. Regional and super-regional shopping centers attract customers because they offer a wide range of goods and services. They do not differ in their functions, the difference is only in the power of attracting customers.

Subtypes of shopping centers

There are also types of shopping centers. There are many of them: a specialized shopping center (Spiciality Shopping Center), a festival center (Festival Center), a power center (Power Center), an Outlet Center, a fashion shopping center (Fashion Center), a discount center (Off-price Center), shopping and entertainment center (Retail – entertainment Center), etc. That is, the name of a shopping center depends on its purpose or the types of goods and services offered in it. In any case, even if various variations are taken into account, the main composition of tenants determines the type of shopping center. The dimensions of the building itself and the site on which it is located, the layout of the shopping center only partially determine the type of shopping center.

Production and warehouse premises

To classify warehouse premises today, two standards systems are mainly used.

The first proposes to distribute warehouse real estate objects into four classes “A”, “B”, “C”, “D”, and in categories “A” and “B” there are two subclasses (A and A+, B and B+) . In accordance with the second, four classes are also distinguished (A, B, C, D), but there is careful detailing, as a result of which the categories look like this: “A1”, “A2”, “B1”, “B2”, “C1” , "C2", "D". Both systems are based on the same principles, differing only in the set of characteristics necessary to classify an object into one or another subclass.

In both classifications, the distinguishing feature of the highest level warehouse is the novelty of the building's construction. The location, decoration and equipment of such facilities must meet the following requirements:

• proximity to main transport arteries;
• the ability to adapt to any type of product;
• high turnover rate;
• guarantee of cargo safety.

Areas belonging to the next subclass can be completely reconstructed using modern materials and technologies. Such premises are approached with almost the same standard as warehouse complexes of categories “A+” and “A1”, with the exception of location (they are often located within the city, in industrial zones and experience problems associated with transport accessibility).

Class “B” includes objects built in the pre-perestroika period.

Class “C” includes former industrial premises, car depots and other objects that were not originally suitable for warehouses.

Class “D” are buildings that were not created for storing anything: garages, basements, bomb shelters, hangars, agricultural buildings. The specific nature of such premises makes their modernization or reconstruction impractical.

Hotel real estate as a commercial one stands apart.

The hotel segment is becoming more attractive to investors both due to a decrease in profitability in other segments and due to the city providing incentives for hotel projects. Experts divide hotel buildings according to “stars”. The distribution of “stars” directly depends on the class of hotel rooms - luxury, junior suite, etc. However, debates among hotel industry experts about whether to consider a particular hotel four-star or five-star do not subside. The Russian hotel complex is very heterogeneous and, unlike other segments of commercial real estate, hotels (especially international chain hotels) almost never openly reduce room rates. This is the peculiarity of this market compared to office or shopping complexes.

Modern trends in the development of society are putting forward new conditions for organizing the work of various business entities. The building in which the offices are located must ensure their normal functioning.

To do this, non-residential premises must have a number of qualities. To make it easier for tenants to navigate the large number of existing real estate market offers, office classes have been defined. Each of them is characterized by a set of qualities. What office classes exist and how to navigate them should be considered in more detail.

Why is classification needed?

The prestige of a particular premises should be taken into account when organizing your own business. To simplify this process, a classification of offices was invented, which has a scale in the form of Latin letters: A, B, C, D.

Each variety has its own qualities. This classification is rather arbitrary, so groups of non-residential premises have their own subgroups. The same is true for the first two categories - class A and class B offices have several varieties.

Knowledge of the features of each premises should be taken into account when choosing them for a certain type of business. The landlord, understanding what class his property belongs to, can correctly navigate the price. It is also extremely important for owners of various companies to take into account the class of the premises. Indeed, without the appropriate conditions, it is sometimes simply impossible to achieve success.

Category A

Class A offices are the most elite types of real estate intended for organizing a business. They are located in new business complexes, where the most favorable conditions for the functioning of offices have been created.

The construction of these premises was carried out taking into account all engineering requirements, and their layout was most successful. The decoration of class A premises is distinguished by modernity and high quality materials:

• all communications and life support systems comply with standards and building regulations;
• it is easy to get to such offices;
• in these premises there are conference rooms equipped with the latest technology, workplaces are equipped with high-quality office equipment and communications equipment;
• Such a business center has high-quality security systems.

There should be a closed underground parking area with an area of ​​1 car per 60 sq. m. office premises. And for workers in such offices all the necessary living and recreational conditions have been created.

Group A subclasses

In order to better understand the main qualities of elite premises, the classes of Group A offices are divided into subcategories A+, A and A-.

In the first case, the premises have all the requirements listed below without exception. However, even the most elite rental properties may have some shortcomings. If these deviations are single and insignificant, the premises are classified as group A.

But in case of non-compliance with several moderately important requirements, the office can be classified as category A-.

Basic requirements for A+ buildings

Elite office classes must have all of the following characteristics without exception in order to be classified as A+.

1. They should be located in or near the central business district, near transport links.
2. The facility must have a transparent system for accounting for operating costs.
3. There should be an entrance group and a foyer.
4. The height from floor to ceiling in 90% of rooms is at least 2.7 m.
5. Secure parking (not counting spontaneous parking) has 1 parking space per 60 sq. m. office space.
6. The energy supply must be at least 50 W per 1 sq. m. rented premises. The heating, ventilation and air conditioning system is at least 2 pipes.
7. The layout is open, with a grid of columns.
8. Fiber optic telephone systems and the Internet ensure full workflow execution.
9. Common areas included in the payment make up no more than 12% of the rental area.

Category B

The characteristics of offices assigned class B differ slightly from the previous category. They may not be as upscale, have a less favorable location, or have fewer services.

Quality standards are constantly increasing the requirements for rented non-residential premises. Sometimes, after several years of intensive use, a prestigious office also falls into a lower category. Class B may lose some of its previously existing qualities.

If a company does not need to rent premises for representation purposes, management most often pays attention to category B. It is more designed for a work environment rather than maintaining the organization’s reputation.

Class B Traits

Office class B is characterized by a number of features.

1. Most often, its location is not so advantageous.
2. Such premises may also not be located in specialized office complexes (previously it was some other residential or industrial building).
3. The range of services is somewhat limited.
4. The decoration of the premises is made of high-quality, but inexpensive materials.
5. Such buildings have parking, but, for example, it can be located in the open air.

These are economy class premises that have a significantly lower rental cost. In general, such offices meet all the requirements of international norms and standards, but their characteristics are somewhat limited.

Group B subclasses

The characteristics of class B offices differ from B+ in the absence of at least one minor parameter. A more elite type of building for organizing offices has a number of distinctive features.

Such non-residential premises can be easily reached along the main road. They are located in new or completely reconstructed buildings. Management and documentation are controlled by professionals.

The height of the premises allows the installation of suspended ceilings. B+ offices have secure underground parking, as well as ventilation and air conditioning systems. High-quality communications of various types are carried out here.

The building must have an entrance and a hall. The elevators work well. New windows provide more than enough natural light. The finishing is made of inexpensive but high-quality materials. If one insignificant of the listed parameters is missing, the office is classified as category B.

Class C

Class C offices are inferior to the previous ones in a number of characteristics.

1. They can be removed from the central transport intersection.
2. Such buildings are characterized by a poor level of maintenance.
3. There may not be sufficient parking space or a complete set of furniture and office equipment necessary for staff work.
4. Most often, such offices are organized in old post-Soviet buildings that were not built taking into account all modern requirements.

Being poorly suited for organizing the work of employees of any company, these buildings are considered unprestigious.

There are no interior renovations; at most, the landlord could restore the facade. Maintenance is either absent or carried out by the owner. There may be problems with paperwork.

But the Class C building has secure surface parking. There is also a 24-hour security system. Most often, although not in sufficient quantities, there are conditions for rest and welfare of employees.

Category D

Class D offices are located in former administrative buildings, institutes and other institutions built a long time ago. As a rule, repairs to them were carried out a long time ago.

There are also rooms that look quite solid from the outside. Usually these are buildings of former institutes. They may even have presentable libraries and printing presses.

But the internal layout and communication systems do not at all correspond to modern ideas about office space. Such buildings can be located anywhere. Getting to them is sometimes extremely difficult.

This segment attracts tenants due to its cost - in this case it is more than affordable. This class of offices is chosen by small firms for which the issue of presentability does not play a significant role.

But the pursuit of savings sometimes results in significant costs, since such premises often require major repairs. The tenant will spend significant sums on it. And the lack of basic canteens, parking and normal life support systems makes the work of the staff extremely difficult.

Having become familiar with the concept of office classes, it will be easier for a tenant to determine which premises are best suited for a particular business.

The new list consists of 26 items.

The Moscow Research Forum announced the update of a number of classification points for office buildings. During the year, the companies included in the Forum discussed the criteria for assessing office buildings and their compliance with modern market requirements. As a result, more than 70% of the classification points were revised in the direction of tightening the requirements for objects.

Let us recall that the Classification of office buildings was developed by the Moscow Research Forum in 2003 and finalized in 2006.

The updated classification consists of 26 points, which group requirements into the main categories: engineering systems, design features, location, parking, property, building management and tenant services. An important innovation was the “Certification” item - the compliance of business centers with international energy efficiency standards, such as BREEAM and LEED. This point is still advisory in nature, but it indicates changes taking place in the market and the growing importance of the environmental efficiency of buildings.

Significant changes have affected the “Parking” item. In connection with the latest changes in the organization of parking space in the city, analysts from five leading international companies have come to the conclusion that it is necessary to change parking requirements. For business centers located within the Garden Ring, the provision of parking spaces has become a recommendation: 1 parking space per 100 sq. m. m of rentable area. For class A and B+ objects located outside the Garden Ring, the supply ratio has become a mandatory parameter:

Between the Garden Ring and the Third Transport Ring: no less than 1/80;

Between the Third Transport Ring and the Moscow Ring Road: no less than 1/60;

Outside the Moscow Ring Road: 1/30 – 1/40 or more.

In general, the requirements for classified buildings have become more stringent. Thus, 7 criteria have become mandatory:

Availability of a central building management system (for class B+)

Availability of heating, ventilation and air conditioning system (for class B-)

The waiting period for elevators is no more than 30 seconds (for class A)

Minimum ceiling height “clean” 2.7 m (for class B+)

The depth of the floor from the window to the “core” should not exceed 10 m (for class A)

Loss coefficient no more than 12% (for class B+)

Availability of an effectively organized reception area (for class A)

The Class B- building classification system has been revised. The building assessment criteria are now mandatory and advisory in nature. To classify a building as a class B- object, all 8 mandatory criteria must be met to ensure safe and fairly comfortable work for office employees:

Availability of heating, ventilation and air conditioning system,

Modern fire safety system,

Availability of modern elevators for buildings of 4 floors or more,

Availability of a video surveillance system and access control to the building,

Use of high-quality materials when decorating common areas and facades,

Availability of organized guarded parking,

Organized building management,

Availability of internal infrastructure, taking into account the existing infrastructure in the immediate vicinity of the building.
