The Company



Company Termoservice Ltd was registered on 28.06.2006. It is structured to operate and perform in the following directions and activities:

 -     Project Design and Management

 -     Green and Sustainable Building Performance

 -     Equipment service and maintenance, installation testing and balancing – in a separate division (see item 4.)

Later on, the major accent of the services has been directed to facilitation of Green building certification performance.

Considered separately, the details of the company’s activities are as follows:


Today, more and more buildings are tending to certify themselves using LEED and BREEAM certification systems. Following this trend of the green building industry, Termoservice team has been developing its skills so that to adequately respond to this situation. Thant’s why, recently after its registration, the company directed its activities towards Green building industry. The major argument for this decision was the profound experience already gained during the participation of Termoservice team members in many and various HVAC design and installation services.

The company is aware of the principles of developing projects that are able to meet the requirements of the certification system LEED (Leadership in Energy and Environmental Design), developed by USGBC (United States Green Building Council). Along with the years of providing facilitation services related to this rating system, some of Termoservice team members have acquired the credential of LEED AP (Accredited Professional) - BD&C. The company is also an official member of USGBC (United States Green Building Council) since many years.

The other world popular rating system BREEAM (Building Research Establishment Environmental Assessment Method), has been also one of the direction, where Termoservice developed some of its activities.

Locally, Termoservice is a member of the BGBC (Bulgarian Green Building Council) since its foundation as of 2009.

The main activities performed by Termoservice related to Green Building Performance are:

1.1.  LEED Certification related:


a)   Commissioning - Fundamental & Enhanced

The Commissioning services are an essential part of the LEED certification process. This is a quality oriented process, which is to be performed by independent professionals, reporting directly to the Owner. The process is focusing upon verifying and documenting that the facility and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owner’s Project Requirements.

Thanks to its profound long years experience in the HVAC field, Termoservice team have been performing the role of Commissioning authority in more than 30 projects.

Termoservice is performing also Commissioning of existing building, inseparable part of LEED EB-OM rating system. For this purpose, the company is equipped with the most sophisticated measuring instruments including Thermal Imager and almost all kind of Data loggers, Electrical and Airflow measuring devices. All electric and thermodynamic values which are to be observed during an inspection of buildings, are measured and registered.

b)   Energy modeling

Energy modeling, or Building simulation, especially the option “Whole-Building Energy Simulation” is perhaps one of the most useful analyses one can do when designing a green building. By means of Energy Modeling, it is possible to make the immediate evaluation of the phenomena of action/reaction that allow the study of multiple “what if” scenarios. For over 10 years, Termoservoice team executes Energy simulations with advanced software for modeling, recognized by ASHRAE, and suitable for LEED certification.

c)   Renewable Energy Production

Analyzing and evaluating systems based on renewable energy sources, it is rarely possible this to be integrated directly in the energy modeling software. The allowed by LEED method is “Exceptional Calculation”. Termoservice has been applying this method successfully to some renewable energy system such as:

-       Solar systems for Domestic hot water needs

-       Solar High temperature solar systems in combination with Absorption chillers

-       Geothermal closed loop heat pump systems

-       Photovoltaic electrical systems

-       Renewable energy based on Pelletes (sunflower waste)


a)   Minimum Indoor Air Quality Performance

This is a specific calculation procedure for verification that the minimum required outdoor air is ensured for the occupants. It is established by LEED on a calculation template and it is a mandatory provision for the certification process. Thermoservice has been performing successfully this calculation for over 30 projects.

b)   Enhanced Indoor Air Quality Strategies – details in LEED Reference Guide.

c)   Thermal Comfort. This is a procedure established to promote occupants’ productivity, comfort, and well-being by providing quality thermal comfort. Termoservice has been providing this procedure by the specialized software “ASHRAE Standard 55-2010 Comfort Model”.


a)   Light Pollution Reduction – details in LEED Reference Guide.

1.2.  BREEAM Certification related

1.2.1.   Credit Category “Energy” Ene 01 Reduction of energy use and carbon emissions

a)  Option 1 - Use of approved building energy calculation software

b)  Option 2 – Energy efficient design feature.

1.2.2.   Credit Category “Management”

a)  Man 04 – Commissioning and handover

1.2.3.   Credit Category “Health and Wellbeing”

a)   Hea – 04 – Thermal comfort

1.3.  SEDA related (Buigarian institution)

Termoservice company is certified by the Energy Efficiency Agency (EEA) to carry out energy audits and certification of buildings in accordance with Art. 44 of the EEL (Energy Efficiency Law) in Bulgaria. The industrial projects audits and certifications are also performed by the company with a partnership with other firms having the respective certificate under ordinance 16-346. Termoservice company is in possetion of the specialized software EECalc for calculation of Energy Audit of buildings, established and recognized by SEDA.

The activities established by SEDA and performed by Termoservice are:

1.3.1.   Conformity assessment, related to Energy Efficiency projects.

1.3.2.   Energy Audit and Certification of already constructed buildings.

For performing these services, the company is equipped also with a wide range of measuring instruments, as mentioned already in 1.1.1. a), and details of them are listed in section “Resources”.


The company has very big design experience and extensive design project data base. For this contributes also the circumstance that Termoservice was founded after the restructuring of the design engineering and service departments of Thermocontrol, Total Air and  Qualitair companies,  whose activities were related to the construction of some of the biggest projects in Bulgaria during the period 1995 - 2006, in the field HVAC&R  (heating, ventilation, air conditioning and refrigeration) and the Automation control systems belonging to them.

Leading HVAC&R designers are with over 30 years of continuous experience and have a Masters degree in their branch. All members of the design engineering team have full Licenses authority issued by KIIP (Association of Engineers in Investment Design, Sofia, Bulgaria). The leading HVAC&R designer is also a member of ASHRAE - American Society of Heating, Refrigerating and Air-Conditioning Engineers.

The main design engineering disciplines practiced in the company are:

2.1.  HVAC&R Design - Heating, Ventilation, Air Conditioning and Refrigeration.

Termoservice designs HVAC systems in the following mannor: maximum efficiency, also with using of renewable energy or energies, produced in the eco-compatible way. In this sense, together with the compliance to the local norms, the systems designed by Termoservice are following the guidelines of the International rating systems, methodologies and standards, especially ASHRAE USA, DIN Germany. 

This includes also any kind of energy optimized projects, using non-conventional and new energy sources such as geothermal heat, waste heat, co-generation systems, biogas, energy recovery concepts and more.

2.2.  Other design engineering disciplines

Termoservice performs as a complex project design package, the so called MEP combination (Mechanical, Electrical, Plumbing), namely:

2.2.1.  Electrical projects - according to intended uses and functions of the project.

2.2.2.  Water, Sanitary and Sewerage and Sprinkler systems.

2.3.  Automation and Automatic control

It is the other major discipline developed within the company.

The  Automation Control of HVAC and other engineering systems is the “Brain”, which is running and managing them. In order an Automation control to be effective, it has to be based on a professionally structured Logic of operation. Termocontrol team is aware that the optimal functioning of the building systems’ Automation requires to be provided with proper Design assignment  – something, which has been mastered within the company during long years practical experience.

2.4.  Project Management

In the dynamic design context, Termoservice understands the importance of applying the project concept in the construction stage of the building development. In general these services could be considered in two parts:

2.4.1.   Tender Procedures

Tenderings developed by Termoservice are prepared not only for projects designed by the company, but also for projects designed by other firms. In a professionally prepared tender documentation, the design solution is presented for bidding so as to encompass all aspects of building installations and to avoid the addition of annexes for missed work, preventing thus an unfair competition between prospective contractors. The consulting activities contribute in presenting a solution for the optimal choice of the installation system and a decision, applied to the selection of suppliers and equipment, accompanied with MSS (Material Sample Submittal) approval procedure. These activities are covering:

a)   Analysis of the design concept and its approval

b)   Preparation of tender documentation and carrying out of tender procedure

c)   Evaluation and consultancies of the tender results.

2.4.2.   Project Management

Company Termoservice proposes and performs the activities associated with a management of investment projects. These activities are directly related to the investor as the project management company in fact replaces the investor in his contact with the contractors. In today's practice, these activities are also known as Investor's Control, Project Management, etc. Their range starts from the design process through the construction of the building until to the issuance of an operation permit (protocol model 16). Termoservice company can perform these services not only within its basic design disciplines described herein, but also for the entire scope of all trades included in the investment process, starting from the architecture, whereby the requirements of the national building codes are followed closely.


Company Termoservice is specialized in maintenance and repair of air conditioning and refrigeration equipment and their automation control, including delivery of spare parts and element replacement.

These services however are performed in a separate department. Detail and contacts could be found on www.termoservice.bg.


With this presentation Termoservice company expresses its gratitude to all its clients and partners for giving it the opportunity to perform and offer its services and activities.
