Designing Heating and Cooling Systems in Large Buildings

Have you ever wondered what goes into a heating or air conditioning system for a large office building or another large building like a mall or a school? My name is Evelyn, and I am an HVAC architect. I design heating and air conditioning systems for large, corporate buildings. Making sure that a large building with many rooms or offices is efficiently heated and cooled is a very large job and is much more complicated than simply heating or cooling a home. This blog will educate the reader on how heating and cooling jobs this large are designed and completed.

Keep Your Headroom Cool: What Attic Fans Have To Offer

Nicole Jacobs

Heat rises, which means that, in the summer, your attic will be the collection place for the majority of the heat in your house. While most homes have roof vents that are designed to give some sort of passive heat exchange between the interior and exterior of your home, this is often not enough to make a significant difference in your house. Attic fans are an alternative that provide increased cooling capacity to your attic, which can translate into a cooler home overall.

The Benefits of Attic Fans

Ventilation: Attic fans will pull hot air out of your attic, and thus the rest of your home as well, and exchange it for cooler air, helping to keep the overall temperature of the interior of your house low.

Mold Prevention: By causing movement in the usually stagnant air in your attic, attic fans help reduce the overall humidity levels. This helps prevent mold and mildew from forming in your attic, from which it can spread throughout your house and pose a serious health hazard.

Energy Savings: Attic fans are much smaller than central air conditioning units, and as such use much less energy. This means that if you use an attic fan to keep your home cool some or all of the time, you will be cutting down on your energy consumption and saving money in the long run.

Types of Attic Fans

Electric: Electric attic fans run off of a standard wall current, and work to pull in cool air from outside whilst blowing out hot air from the interior of your home. They can be installed so that they move air throughout your home, and as such can be used to cool down your entire house, either in tandem with or in replacement of conventional standard air conditioning.

Solar: Solar attic fans are identical in function to regular electric attic fans, but instead pull their power from solar cells attached to the roof. This means that your energy bills will be reduced over time because you will not need to pay for electricity to power your attic fan. It also means that your attic fan can continue to work even in the event of a power outage. The major drawback of solar powered attic fans is the fact that they only work when the sun is shining. However, it should be noted that attic fans will only need to ventilate your attic when the sun is shining because this is when heat is most likely to build up within your home.
