One of the biggest problems of Iranian people is the high rate of energy waste in cooling, heating, and lighting systems, which on one hand increases the costs of energy generation and on the other hand solving this problem requires costly methods in order to increase the efficiency of energy consumption. What is more, this issue brings the complexity of energy source management for the government. This event has been highlighted with the population growth; also the limitations of energy sources has increased the importance of reviewing this problem.
Greatest Energy Cost of Houses: Allocation of more than 50% of energy consumption of a building to heating/cooling and air conditioning systems (HVAC)
Sedna has considered two essential solutions to reduce the use for 20% in heating/cooling systems. The first is to use different scenarios for the products' performance. The ability of 24h programming in Sedna products considerably decreases energy consumption as a result of temperature and light difference during night and day. The second solution to decrease the cost is to accurately review and analyze the monthly and yearly consumption rate. As the controllers of light and energy use become smart, you can have the most optimal energy consumption along with appropriate temperature and lighting conditions in your environment.
Based on the 19th topic of Iranian national construction laws, which deals with the issue of being economical in energy consumption, the comfort zone in a building is heating and moisture conditions in which about 80% of the residents and users feel comfortable. On the other hand, factors such as heating degree day and cooling degree day, the definition of which is as below, are two important parameters to control an environment's temperature. In sum, an appropriate heating and cooling system is one that can make balance between the two parameters of heating degree day and comfort zone in cold season, and cooling degree day and comfort zone in the warm season, so that energy consumption in both cases remains optimal.
Based on this document, the necessary energy saving in buildings is determined by some main factors such as the building's use type, geographical classification, the useful building area, the city of the building, and the building's classification. Sedna's cooling/heating controller products are designed in a way to take all the above items into consideration with 24h programming for throughout the year and while providing desired temperature conditions, it will guarantee the optimality of energy consumption.
This law has also considered some regulations to control the energy consumption via lighting systems in building spaces. Paying attention to systems of lighting reduction, spaces' benefit from natural light, control for turning off the light, etc. are some reasons that made Sedna Group to focus on the ability of smartness concerning the environment's light, time, trainability, and 24h programming throughout the year in its lighting controller products. Consequently, by means of simple control of temperature and lighting in buildings, concerning the regulations zone, the energy consumption of these two groups can be easily reduced for many percent.
