The latest energy-saving solutions and technical improvements offer great potential for energy savings.
However, in order to ensure long-lasting, energy-efficient and efficient functioning of the building, continuous, properly conducted operation is necessary and maintenance of technical installations. In order to meet these requirements, an Action Plan has been drawn up presenting the energy saving measures that will be implemented to meet the criterion of energy efficiency of the building during its operation. The plan, in addition to specific actions, also includes commitments to adopt general principles of proper energy management. Tools have been indicated that will make energy efficiency a priority in the field of management at every stage of the life cycle of a building and its systems.
The following Action Plan covers issues related to elements of pro-ecological policy, operation and maintenance of technical building installations as well as a measurement and verification plan contributing to optimizing energy consumption and ensuring high quality of the internal environment in the building. The influence of the use of technical installations by the building staff on the final energy consumption and the need to make users aware is also underlined. In addition, a number of activities have been described to ensure an optimal environment for the building user. The adopted parameters of the internal environment have a direct impact on the health, efficiency and comfort of users. Maintaining high standards inside buildings allows to achieve higher efficiency of work or rest, which, for example, by reducing absenteeism can provide tangible benefits for the employer, building owner and, consequently, for the whole society.
Technical installations of the building will be under constant supervision provided by an external company that has 24/7 support and monitoring.
Technical security will be guaranteed by maintaining on the move and efficient and safe functioning of technical installations in accordance with the set parameters and regulations. Permanent monitoring of equipment status and periodic inspections may contribute to the extension of equipment life, and the preventive failure prevention system implemented in this way will allow to optimize energy consumption, reduce the costs of servicing the building and eliminate unforeseen events.
The process of maintaining and maintaining the installations in the building will be fully documented. Data and information on all failures and service events, including detailed descriptions, will be collected.
Taking care of the most accurate results of measurements and compliance with legal requirements, these devices will undergo periodic legalization and calibration.
Devices with high quality and longevity will be used, and operation and maintenance will be carried out in accordance with the principles of energy conservation and care for the comfort of users. Periodical cleaning of ventilation ducts and filters will be performed to prevent the accumulation of dust and microorganisms and excessive increase of air flow resistance, and thus increase of energy consumption needed for air transport to rooms.
A system for reporting corrections and defects by employees, operating 24 hours a day, 7 days a week, was implemented. For this purpose, specialized software was used to support technical service and to provide “help desk” services.
Full exploitation guarantees installation efficiency in a long period of time, quick intervention in the event of a possible failure and the possibility of scheduling fixed costs over a longer time horizon. The principle of reconciling all major changes in the structure and systems of the building in the context of the impact on energy consumption has also been implemented.
A measurement and verification plan was implemented to assess the energy efficiency of the building and ensure its constant optimization.
Within its framework, the necessary infrastructure was ensured enabling constant measurement of energy consumption in a building over a given period of time . The technical installations of the building are controlled and monitored by the Building Management System BMS (Building Management System) ensuring simultaneous reporting of the technical condition of the installation. In this way, easy and quick access to information about the current and past condition of the building is guaranteed through a logical system of data archiving. In addition, invoices for energy are collected and archived, and an electronic document flow system is implemented.
Collected data is used to test the energy efficiency of a building and its installation, comparing the expected energy consumption with the real one. Annual reports will be created that interpret the results of measurements and indicate the most important energy consuming elements. These analyzes will enable optimization of energy consumption in subsequent years.
Further optimization, in addition to the standard measurements of electricity, water, etc., will allow control measurements of the main air streams in the hygiene ventilation system, enabling the required amounts of fresh air supplied to individual rooms of the building.
Extensive analyzes based on energy simulations have been carried out as part of acquiring reliable information about the building.
- Computer simulation using software based on the hourly building simulation methodology – Design Builder
- Analysis made on the basis of the methodology for the elaboration of an energy performance certificate in Poland.[/ Showhide]
Technical installations have been adjusted after the building has been put into use and fully occupied, to take into account the actual working hours and the number of building users.
Optimized system operation is guaranteed while ensuring proper working conditions. The risk of using excessive amounts of energy due to, for example, excessive heating or cooling of building interiors has been reduced
Buildings generate significant amounts of waste every day.
To limit their number, a waste management policy has been introduced within which
public areas have been designated intended for the segregation of recyclable waste, such as paper, plastic, glass and batteries. In this way it will be possible to reduce the amount of waste exported to landfill.
Materials that are least polluting are used to prevent contamination in the building.
Paints, linings and other materials used for minor renovations should contain a minimum number of volatile organic compounds ( VOC), formaldehyde and not contain carcinogens and sensitizers of volatile substances.
In the .big building, you should regularly carry out maintenance of ventilation and air conditioning systems.
The frequency of maintenance operations depends on any failures and associated
operational problems, as well as whether previous maintenance was carried out properly and with due accuracy.
The ventilation system ensures an adequate level of air filtration, thanks to the use of filters with a minimum F6 class on air-fed banets. In order for the level of cleanliness of the air supplied to the building to be at a high level at all times, installed filters should be replaced in accordance with the manufacturer’s recommendations, at least once a year or immediately after finding their improper condition. In addition, the ventilation and air conditioning system should be mechanically cleaned. These systems should be cleaned of dust and substances harmful to health, among others bacteria and fungi that can cause allergies and respiratory diseases.
Incorrectly operating ventilation and air conditioning systems may contribute to the deterioration of air quality in the facility. People staying there may complain of fatigue, shortness of breath, decreased concentration or allergies and respiratory diseases. All maintenance operations should be performed by a specialist company.
In the .big building, the ventilation system ensures an adequate level of air filtration, thanks to the use of F7 class air curtain filters.
You should take care and control devices – measuring the concentration of carbon monoxide (CO) and gas (LPG) placed in underground garages.
The device should be inspected regularly, and all irregularities and failures should be removed immediately. [/ showhide ]
In a .big building, system failures should be regularly removed: water and sewage, fire, central heating, process heat and heat.
Installations should be serviced by specialized companies. In hot water from the water supply network and devices regulating humidity there may be a legionella-type bacterium that causes Legionnaires’ disease. Improperly operating kitchen installations may contribute to gastrointestinal diseases.
A cold water leak detection system has been installed, so you can avoid significant water losses that might otherwise go unnoticed.
In addition, a system of protection against uncontrolled water leaks from the toilet system was used by using motion detectors coupled with electro-valves. [/ showhide]
In order to ensure the highest comfort of building users, it is necessary to supervise and control companies dealing with internal installations.
Proper control and supervision of the work carried out by specialized companies will ensure the proper performance of services, and thus it is going to ensure the right parameters of the internal environment.
Additionally, the technical condition of the building should be regularly monitored. The building should be periodically inspected and reviewed in accordance with the Act of 7 July 1994. Construction law (Journal of Laws No. 89, item 414) and the Regulation of the Minister of Infrastructure of April 12, 2002. regarding technical conditions that should be met by buildings and their location (Journal of Laws No. 75, item 690). Inspections and inspections should concern both building partitions, chimney ducts as well as other internal installations.
The energy consumption of a building depends to a large extent on the people in it and the way they use installed devices and systems.
Therefore, it is very important to make staff aware and provide them with the necessary knowledge about the individual components of the system and their correct service that contributes to the minimization of energy consumed. Taking this fact into account, public information was prepared for building employees showing the correct, energy-saving service of systems in the workplace. In addition, an internet portal was created – a page of the building where information about energy saving measures as well as HVAC systems installed in the building and how to adjust them to ensure the highest possible comfort of use of the building.
