What three does an excellent building energy system include

1. Solar photothermal system: a system that converts solar energy into heat energy for heating, refrigeration and other applications, mainly in construction Including solar hot water supply, heating and air conditioning systems. Solar photovoltaic system: a power generation system that uses the photovoltaic effect to directly convert solar radiation energy into electrical energy, referred to as photovoltaic system.

2. What systems are included in the design of renewable energy building application systems: solar photothermal system, solar photoelectric system, natural lighting system.

3. - Lactic acid energy system Lactic acid energy system refers to sugarThe energy system of ATP is re-synthesized in the process of anaerobic decomposition of raw or glucose in the cytoplasm to produce lactic acid. Its maximum energy supply rate or output power is 23 J·kg-1·s-1, and the power supply duration is about 33s. Because the final product is lactic acid, it is called lactic acid energy system.

4. Building Energy Management System (BEMS), Home Energy Management System (HEMS).

How the Internet of Things is applied to building energy conservation

Building energy conservation requires the use of the Internet of Things technology to perceive and collect data in real time with sensor devices, connect the building to the Internet through wireless network, and realize the exchange of information. And control.

Intelligent buildings in the design, construction and operation and maintenanceThe following Internet of Things technologies may be used: Automation System: Intelligent buildings need an automation system to control various equipment, such as lighting, HVAC, security and audio and video equipment.

Commercial office building: Intelligent building management system can realize intelligent management of the internal environment and equipment of commercial office buildings. Administrators can monitor and adjust the temperature, lighting and other equipment in the building in real time through the system to provide a comfortable office environment.

Introduction to the construction engineering of intelligent system of low-carbon building energy management?

The main system of intelligentization in low-carbon construction. Low-carbon construction technology is still a new technology under development. The construction of China's Beijing Olympics and Shanghai World Expo has integrated the low-carbon concept.

Low-carbon construction means that when building material manufacturers produce building materials and equipment, when owners use buildings, and builders try to improve energy efficiency, reduce energy consumption and reduce carbon dioxide emissions when buildings when building and demolishing buildings. It can be seen that low-carbon buildings emphasize the energy consumption and carbon dioxide emissions of the elements that make up the building.

Low-radiation glass: By using low-radiation glass, the outward transfer of indoor heat energy caused by radiation can be greatly reduced, so as to reduce electricity consumption and achieve the goal of emission reduction.

Through low-carbon design, low-carbon energy use, low-carbon creation, low-carbon monitoring, low-carbon operation and low-carbon emissions, it creates an atmosphere of energy saving and emission reduction and highlights a concept of green environmental protection. Low-carbon emission reduction is not a matter of point, but a whole process of realization, and intelligent technology is also included in it.

What is the Building Energy Management System (EMS)?

1. EMS, that is, the energy management system. It is a computerized system that combines science and technology with management (technology, business, policy, etc.), which can be used to monitor, analyze, control and optimize the use, production and distribution of energy and water resources.

2. The main functions of EMS are: EMS Energy Management System is a company-level integrated intelligent system integrating data acquisition, process monitoring and energy scheduling.

3. The EMS system is an energy management system. EMS is a set of electrical energy management systems suitable for low-voltage power distribution systems with the characteristics of strong professionalism, high degree of automation, ease of use, high performance, high reliability, etc. according to the needs of users and in accordance with the standard specifications of the power distribution system.

4. The role of BMS: to ensure the normal and safe operation of the construction equipment system and the public safety system. The role of EMS: to deliver international and domestic emergency letters, documents, financial bills, commodity samples and other documents and items to users with high quality.
