>> Providing phase one to employers which is included designing and providing documentation and project plans with regard to alternative choice of them.
>> Infrastructure design is to smart making and optimizing energy consumption.
>> Providing project execution description and maps details.

Engineering procurement:
>> Providing Meter and estimating of material consumption,
>> providing specifications of selected machines for the purchase process (Engineering procurement) and provide comparison tables with regards to the types of goods , advantages and disadvantages, prices, rate of power consumption and time of returning capital.
>> Monitoring the purchasing operation.

Supervision:
>> Monitoring on executive operations of contractors as a representative of the employer
>> For monitoring the action of designing operation, buy and run (third part) participating in projects as a representative employer.

Reverse engineering:
>> Perform reverse engineering is consist of investigating, giving data and calculating in order to provide solution to improve the sick buildings condition according to the heating and cooling existed facilities (In particular , commercial and office buildings with heterogeneous pattern of distributing of temperature and humidity)

Administrative services:
>> Performing of systematic contracting projects by using the most qualified technicians executive and utilizing the software to control the operation of the project. Areas where technical and engineering services are available:

1. Air conditioning
Air conditioning systems (heating and cooling) are responsible for welfare conditions for users. This is important and different according to types of users and region system installation that are cause of its extensive range of equipment and systems. Thus providing an overall solution or thumb calculations would be far. Performing the necessary technical visits and calculations are felt Due to substantial financial burden of its equipment in various projects in order to avoid any duplication and selecting the desired.
Providing consulting services are based on experience in executing of industrial construction and sanitary by using the related software on one hand and utilizing of the latest achievements and technologies with approach for reducing the basic costs and increase productivity, which is included by selecting the appropriate equipment capacity and consistent with the user and demands and climatic conditions that are caused a 30% in staff efficiency in energy and function in addition to provide technical calculations and financial (such as return on capital and to consider cycle synchronization of consumption) providing detail engineering services , regulatory services and even the executive.
In answer to various questions raised on whether such services are limited to buildings under constructions or not? We can point out Dozens of office and industrial buildings which were known as sick buildings and those users whom were suffering from undesirable patterns of temperature and humidity that after testing and calculating and providing a systematic problem-solving strategies and executing solutions in some cases which was done by the personnel of this group.

2. Purifying of drinking and industrial water
Today, with increasing population and development in industry and production, it has increased the water demand, in home sections and drinking and industrial section.
Consuming water is provided by two source of ground water and surface water due to proximity of various minerals and organic contaminants that are having lots of impurities , ion-exchange and RO and requires physical and chemical treatment methods which are (reverse osmosis system , disinfection, filtration and...)
In order to the design of optimizing water purification systems 3 fundamental question has to be answered :

1) What water should be filtered?
2) Why and for what consumer it should be filtered?
3) How much should be filtered?

Peyman’s water and facilities group with its experienced and capable staff with experience in water purifications system , is able to provide the best way to purify the water to consumers.

3. Pool, Jacuzzi and Sauna
Today demand is increasing for entertainment, sport and therapy systems including pool, Jacuzzi, sauna, various ponds and etc in public and private projects.
Peyman’s water and facilities group offers the four-fold water filtration of pool and Jacuzzi, with utilizing the modern methods of the world in filtering systems of pool and Jacuzzi and their high experience in this area and with possession of world’s most advanced equipment.
The four-fold of pool and Jacuzzi water purifications includes:

1. Circulation
2. Filtering
3. Cleaning
4. Testing

4. Refrigerator
Calculations and selections of devices are possible for refrigeration to below zero and above zero and cold storage for the particular users, such as precise control of temperature and humidity range or type of filtration and as well as perform temperature specific scenarios.

5. Energy sector
In the pattern of energy consumption of country, residential and commercial sectors are the major consumers of energy compared to other sectors such as industry, transport, agriculture and health.
Considering the variety of users, in commercial and residential, the biggest share of energy consumption is in this sector and are spent on cooling and heating and air conditioning, hence the use of the facilities and equipments with high efficiency and greatest saving in energy consumption and it has considered the quantity of economic and structural building, it has been of particular importance.
Therefore Peyman’s water and facilities group have tried to provide consulting services and considering the design criteria for different users, and provide the correct way to evaluate, compare and select the heating and cooling facilities according to economic considerations and the demands of employer, to choose the appropriate (systems and equipments) that can reduce the costs and energy consumption.

6. Re-engineering (reverse engineering)
Reverse engineering, is involved in problems of buildings and available spaces. For example in some office and commercial buildings heterogeneous distribution of temperature and humidity or the lack of fresh air are caused to increase fatigue and reduce efficiency and adverse effects based on standards it’s to be considered effective factors to reduce efficiency.
Peyman’s water and facility in field of reverse engineering has provided investigation, visit, calculations and getting technical feedback, comparison tables, design justifying and technical executive solutions for problems.

7. Balancing operation of climate
This operation can be performed in order to match the operation conditions with designed cases. This important is caused in increasing the efficiency of upstream equipment such as chillers, cooling tower, air handling, packages and etc in C.A.V and V.A.V systems and transmission equipments such as pumps and fans, as well as downstream equipment such as fan coils , exhaust valves, piping network and canals.

8. Intelligent infrastructure
Activity in this sector in industrial projects (E.M.S) and in residential projects are to develop the comfort level, getting data and efficient use of equipments, energy carriers and also considering the development plan.

9. Clean rooms
The important influence of temperature, humidity and pollutants needs specialised designing and supervising which results and performs in sensitive sites such as pharmaceutical factories, dairy and food and health centres as well as operating rooms, specialised labs (petroleum and paint), control centres and data processing centres.
This requirement requires design and implements systems of clean rooms in classrooms of A B C... in order to achieve stable conditions of temperature, humidity, pressure and etc, monitoring and controlling according to the plan conditions, can be applied.
