Coordination and teamwork between architects, HVAC designers, MEP consultants and contractors using BIM technology can generate energy-
Efficient HVAC systems with minimal environmental impact.
A comfortable life depends mainly on efficiency and duration
The long-term performance of the MEP system in the living space, whether it is residential, office or business district.
The energy consumption of the building will affect the efficiency level of the building, thus affecting the global energy consumption and ultimately the environment.
Optimizing the performance of HVAC systems can significantly improve energy consumption and living standards.
Intelligent MEP Engineering design is required to achieve this level of performance.
In this article, we will learn what is needed for efficient HVAC system piping design and how we can advance those designs.
HVAC service is called HVAC service.
The energy efficiency of HVAC systems generally follows the principle of using less and making full use of existing resources to save money.
The energy cost of HVAC is the main component of the entire energy cost.
To better understand the efficiency of HVAC systems, understand how the different services of HVAC work.
How do different HVAC systems design HVAC to improve efficiency?
Usually, the energy efficiency is with Seer-
Seasonal Energy Efficiency ratio of BTU (
British heat units)
For the cooling system, that is, the ratio of the cooling output (in BTU)
Divided by the electricity consumption of kwh.
The higher the number, the higher the energy efficiency of HVAC.
Some of the most important features for general HVAC efficiency are: several factors for HVAC energy performance decision makers can influence HVAC energy performance targets.
Reducing energy costs by nearly 30% years can be increased
Performance of HVAC unit.
Higher savings can be achieved through natural ventilation in summer and the use of highly insulated warm walls and window surfaces in winter.
When the design objectives are determined early on, the design team knows what to do before the construction document phase.
Design team communication can also be prioritized.
According to U. S. data, HVAC systems account for 32% of building energy consumptionS.
Department of Energy.
How smart design can help plan Energy
Efficient HVAC systems that reduce costs and environmental degradation? Energy-
Efficient HVAC design ultimately requires greater effort and collaboration from the design team.
Design goals need to be decided in advance.
For example, the energy source code requirements and HVAC systems that use 40% less than the local code will have different designs.
There may be differences in component size and System Type.
Size is important.
In order to improve energy efficiency, the dimensions of the HVAC system must be appropriate.
Oversized devices tend to be less efficient and cost-effective than the right size.
An example is the oversized cooling system, which does not perform proper dehumidifying of the air, resulting in a cool but "damp" space ".
The design of the HVAC system must focus on the expansion, but not necessarily the change of the building.
Adding new technologies can lead to demand for more cooling.
However, providing excess capacity before making an expansion decision can be a waste.
The device may be out of date when these decisions occur.
Nevertheless, in order to save construction and operating costs, additional physical space should be provided for additional boilers, chillers, pumps and cooling towers, and the distribution system can be designed to accept additional equipment, and expand according to future needs.
Modular equipment can also be considered in mechanical rooms.
Ideally, the building design should include all the features to reduce the load of HVAC.
Some examples are: Other ways to reduce HVAC loads include using systems that work partially efficiently
Load, for example: Since carbon dioxide emissions from fossil fuel combustion provide heating and cooling in buildings, intelligent and efficient design plus regular maintenance can reduce the generation of carbon dioxide. BIM (
Modeling of Building Information
MEP engineers are increasingly looking to help design energy-
Efficient HVAC system.
To achieve greater success, using BIM becomes critical
Train personnel early in the HVAC design process to ensure the accuracy and reliability of the final design.
Since 3D graphics are connected to data-
Rich intelligent objects that carry component specifications, modifications made on one component are automatically updated anywhere the component appears.
Therefore, for HVAC designers who are good at using BIM technology, HVAC design changes are easier and more effective.
BIM technology is particularly helpful for HVAC systems when HVAC designers download data to run HVAC load and performance calculations.
Components can be moved, edited or modified to improve performance while automatically updating said changes on all drawings and other design services, including MEP construction drawing services.
With multiple views, the piping system design can be routed to achieve efficient airflow and avoid conflicts with structures or electrical or plumbing elements.
For all of these elements, gaps can be fully maintained, and the placement of hangers and brackets can follow industry codes and regulations, warning designers when codes are violated using geometric parameter rules.
Seamless coordination and teamwork between architects, HVAC designers, MEP consultants and contractors is critical for efficient design and construction of energy
Efficient HVAC systems with minimal environmental impact.
This collaborative effort with BIM technology is the way to advance efficient HVAC systems.
