“What is the basis for building energy efficiency in the U.S and much of the world?”

 

With the onset of global warming, energy efficiency has become a great necessity. As such, buildings in the U.S must now follow a certain standard so that after construction they will meet the sustainability requirements dictated by ASHRAE Standard 90.1. ASHRAE Standard 90.1 is a compilation of all of the codes for building energy efficiency (with the exception of low rise residential units) and is updated every three years to ensure that the next set of codes will be 15 percent more efficient than the previous.

Cradle to Gate Life-Cycle Assessments

“How can we analyze the portion of the lifecycle of a product?”

 

Life-cycle assessments are done on projects to determine their total impact upon the environment. However, sometimes we may only want to know the impact of a portion of their life, specifically from resource extraction up until it leaves the factory. One way to accomplish this is to use something known as a cradle to gate life-cycle assessment. This process is very useful for manufacturers to determine what their contribution to climate change is.

“How can we design humidifiers for industrial needs?”

 

Humidifiers are widely used to make personal spaces much more habitable. However, can this technology be utilized for industrial applications as well? Well, it turns out that many processes actually need to be undertaken in less dry conditions because static air friction becomes more prevalent. To illustrate, the this buildup of dry air in data centers and manufacturing facilities could cause static electricity to discharge. Art museums also need to keep paintings at a certain humidity to protect works of art. As you can see, there are in fact many many industrial applications of humidifiers!

“How do we evaluate buildings after they have been built and used?”

 

Modern Buildings are designed to function in a certain way. However, after they have been built, unforeseen factors can disrupt things and cause inefficiencies. So how can we evaluate buildings in an effective and rigorous manner after they have been constructed? Well, after many years of research, building professionals in both the U.S and Scotland have developed something called a Post-Occupancy Evaluation, which involves authorized individuals to arrive onsite an perform audits. Once an evaluation has been done, further action can be commenced to bring the unit to full operation

“How can we achieve radiative heating?”

 

Radiative heating has a plethora of energy and ergonomic benefits. However, how can we put this idea into practice? Well, we know that we can use heat exchangers to transfer heat from one medium to another. So what if we were to simply build a specialized model to transfer heat to the surrounding atmosphere? Well, this mechanism is known as a radiator and has become one of the most common HVAC appliances in the world.

“How can we provide hot water for district heating?”

 

District heating is world-renowned for its ability to provide large urban communities with the heating that they need. However, how exactly can we provide them with the water that they need? Well, what if we were to have generators that instead of generating electricity would generate hot water? Well, this is the idea behind a Heat-only Boiler Station and is one of the prime elements in modern-day district heating systems

“What is the future of building energy information gathering?”

 

If we can know the energy consumed by a building, then we could learn and do a lot. We can observe any energy-related anomalies, or at what times are our peak usage. To streamline this, we can implement something called an Energy Management Information System, or EMIS. EMIS’ can store and analyze building energy data through a collection of hardware sensors, data in computer banks, and data from the web. From here, we can then take action, and truly optimize our operations!
