Artificial Intelligence (AI) is proving to have promising application in construction industry. Seeing how HVAC systems contribute to the largest share of energy consumption in commercial and residential buildings, energy efficiency measures that target HVAC can help achieve major savings. AI can help improve both energy efficiency as well as indoor air quality by optimizing airflow, humidity and temperature while maintaining the lowest possible energy consumption.

However, it is advised that energy saving HVAC upgrades should not hinder with the indoor environmental quality as it can cause discomfort and health issues in some cases too. This can also have a negative impact on productivity at work places and business settings.

Let’s take a look at how AI can improve HVAC efficiency with the following cases:

HVAC control

Controlling an HVAC system effectively becomes quite a challenging task when the building conditions are constantly changing. Consider the following scenarios:

With changing outdoor temperature, the heating or cooling required to maintain a suitable indoor temperature is affected.
HVAC control and optimization is also affected by indoor activities. For example, a commercial kitchen would require more ventilation than an work place of the same size.
The ventilation requirements and temperature control systems are also affected by people entering and leaving the buildings.
All the above situations cannot be efficiently managed with manual controls for optimal performance. This is where AI makes the job easy by allowing smart control systems that process real-time data and adjust the HVAC systems accordingly. This helps HVAC systems to operate at peak optimal performance even with variable building conditions.

Smart Controls for Ventilation Systems

For optimizing ventilation systems, considering the outdoor airflow for determining the optimal variables is a must. Air Handlers consume less energy than space heaters and air conditioners. However, the outdoor airflow determines the heating and cooling needs of a building. For example, if the outdoor airflow is increased during winter, more heat is needed to maintain the suitable indoor temperature. The same can be applied for air conditioners during summer when ventilation system increases outdoor airflow.

Many buildings have ventilation systems operating at full airflow. This leads to a major waste of energy. Overventilation leads to energy wastage while underventilation leads to detrimental effects on indoor air quality. Ventilation system coupled with AI can determine the optimal airflow for maintaining a suitable environment of the building. AI can also keep a track of number of occupants and also the air pollutants concentration. It is highly recommended that the ventilation systems should never reduce the airflow below the required minimum value as suggested by the local building codes.

Optimizing Space Heating and Air Conditioning

According to a study by Lawrence Berkeley National Laboratory (LBNL), peak human productivity is reached when the indoor temperature is around 22 degree Celsius. The study also observed that as the temperature increases or decreases, it caused discomfort and lowered the productivity. Extreme temperatures are highly unlikely even with deficient HVAC systems. However, the indoor air quality degrades gradually as the temperature diverges from the ideal range. Improved and efficient performance is possible with AI enabled smart controls for the HVAC system.

Building furnaces, boilers, chillers and other HVAC equipment are now available with in-built AI. Thus, major energy savings can be expected just by upgrading the old equipment. The use of smart controls leads to efficient working of the entire HVAC system at all times.

AI Synergy with Energy Efficiency Measures

Based on the previous points, it is evident by now that energy efficiency measures are more effective when coupled with artificial intelligence. Two examples of HVAC upgrades that work best with AI are Airside Economizers and Energy Recovery Ventilations.

Airside economizers can help save energy in some climate conditions. When outside air is within suitable temperature and humidity range, the economizers increase ventilation rates and reduce the need for air conditioning. Since ventilation fans need less energy than air conditioners, electricity can be saved. Smart controls can further maximize these savings.

In energy recovery ventilation, when the outdoor airflow is optimized, the energy wastage for heating or cooling is avoided. ERV can then exchange heat between supply air and exhaust air, ultimately reducing the workload on HVAC even further, ERV works for both summer and winter by maintaining suitable temperature with indoor air precooling or indoor air preheating.

A home loan has to be a decision that has been thought over from all angles and aspects. Missing any of the integral points can result in you choosing a housing finance company that leaves a bitter taste in your mouth. We all want the whole process of purchasing our own home to be a very pleasant experience that we can cherish for a long time, without any negative memories. Well, finding the ideal home loan is the first step in that process. When we think about all the factors that pertain to the perfect home loan, we can more easily identify the best among all the options presented to us. Research many housing finance companies, compare several home loans and weigh all their features before making a decision.

Housing Finance Company: It’s exceedingly important that you know everything there is to know about the financial institution that you choose. Don’t be tempted by just the gloss and glamour on the outside, but instead make sure that you’re thoroughly aware about their reputation with their customers. Read testimonials and speak to friends and family, who’ve used the same lender. Find out if they were satisfied with the service provided by the housing finance company and what complaints and comments they have to make.

Interest Rates: Finding the best interest rate is an extremely important aspect of every home loan process . It decides the amount of EMIs that we have to pay every month and hence how much we need to cut off from our budget. This singular factor can decide how much the home loan will costs us over a period of time. The best way to find low interest rates is to browse through and compare the varied options that lenders provide for any additional benefits being offered. An interest rate that’s low, is from a reputed bank and still offers us many advantages is the best one to opt for.

Loan Tenure: This is one of the most important parts of any home loan that we choose. If we choose a home loan that lasts for a very long period of time, we risk paying a lot more interest than we should ideally need to. However, very short loan tenure can result in high EMIs. Hence, it’s important to ensure that we find the perfect balance between the two and pay off the loan in steady and slow instalments.

Ensure that you think through your home loan decision thoroughly and find out all that you have to. Get all your questions and doubts answered before signing any paper and ensure that the entire process is transparent. Choose the best home loan now.

Erection problems are classified as erectile dysfunction which has many causes varying from physical to psychological. Even minor tensions like change of place can have its effect on male’s performance in bed. Amongst common causes of erection problems issues related to reproductive system and physical health are the most common. Males suffering with low testosterone and poor testicular functions, having restricted flow of blood, suffering with problems related to nervous system, having deficiencies of vital minerals or undergoing any treatment which has side effects are common victims of ED. Psychological issues like anxiety, depression, etc., take away male’s focus and harm his nervous system and are common causes of erection problems.
