Check out this map that shows a near building level energy analysis of New York City. The map also estimates the heating, cooling, electricity and hot water use of each block.
The map represents the total annual building energy consumption at the block level (zoom levels 11-15) and at the taxlot level (zoom levels 16-18) for New York City, and is expressed in kilowatt hours (k Wh) per square meter of land area. The data comes from a mathematical model based on statistics, not private...
Energy-models have become more popular in the last couple years - this is certain. This is in part due to ASHRAE, LEED, and increased computational power.
So you could ask, "How successful is energy-modeling?".
Let's take a look at the [current] ultimate metric for environmental success - Global Warming.
I've heard that a way to measure global warming is by arctic populations, especially that of tertiary predators - chiefly the polar bear. While watching the Big Game, I witnessed something that gave indisputable evidence that the polar bear population is thriving, and possibly even evolving.
The number of polar bears shown over the passed few years has grown exponentially, which indicates healthy arctic...
I'm sure one of the items is getting a clear picture of the building, which often means looking at drawings, and mechanicals.
Often, it's best to talk about the model with a person that knows the building well or asking them to describe it. In the case where you ask for the building inputs, those unfamiliar with energy modeling often send unnecessary data, but miss key components.
However, if you send them this form, and ask them to fill out and include your email. BOOM! You can receive the basics requirements you need to build a model.
In fact, with this...
Let's cut straight to it:
LEED background information:LEED energy models have a default requirement that process loads and receptacles are 25% of the baseline building costs. The total cost must be identical in the proposed LEED model.
However, this assumption is based on a standard office building. Thus, if the process loads and receptacles are designed and documented (think spreadsheets, or even a basic description), one can use the actual designed loads. This can yield free leed points, bascially LEED plus a little math gets you 2 valuable LEED points.
Example LEED Case Study:....LEED + Math = 2 Points!
Let's consider a building that has 31% savings on the proposed...
So, you need to implement percent glass calculations in LEED? This has proved a bit confusing since the additions of doors to the "openings" and I think it requires explanation.
What's the relevance? Well, if you are near 40% glass, or say you're half glassed - this could make or break your model:
Here's the reason why: The TRACE 700 reports calculate the glass based on the Wall area only (and not the gross wall area, which includes Opaques doors). So if you have doors, your TRACE reports may over-estimate the percent glass. Let's take an example of a building that is "Half-glassed":
Let's take an example: Alternative 1:...So you have just completed an eQUEST run and you want to send your reports to a colleague by email. You are wondering, "how can I print to pdf?". (or maybe you are getting an error with your current pdf software).
Well, you could spend hundreds on special pdf software, but there's a free way to do this. You can even print all of your reports into one pdf!
How do I print to pdf for free? Download PDF printing software. We recommend free and lightweight...The energy modeling industry is always changing, with anything from updates to energy modeling software to new regulations and protocols.
If you think about it, the value in energy-modeling is the ability to predict the future (in terms of energy cost). So, we thought, why don't we take it one up, and predict the future of the industry for 2012.
LEED continues to be the golden gooseLEED is an amazing thing. It's become a sort of self perpetuating revenue generator. USGBC has done an amazing job marketing building efficiency to the general population.
Now building owners are aware of this "LEED" thing that makes their buildings more appealing to tenants (appealing = higher lease rates). And all that is great for...
As 2011 comes to an end we thought we could do at least one cliche looking back list. Our forum continues to be a great learning resource for energy modelers. There are a lot of great discussions and knowledge dumps going on. I'd encourage all Energy-Models users to check it out. Here are the top 10 most popular forum entries of 2011.
Dedicated OA and Split System in TRACE 700 ASHRAE - Building Energy Modeling Professional (BEMP) Certification Program...Energy-models.com is proud to announce a new advanced section in the eQUEST online course. While there are more videos in production, we have just released these popular requests (most of them are related to LEED or to help yield more LEED points):

When it comes to energy, I suppose we are all hypocrites at some point. I mean, look at Al Gore flying around in a private jet. Of course, Al Gore isn't exaclty going to come clean on his hypocrisy. But, that's because he wouldn't make millions on his powerpoints movies.
Anyway we here at energy-models.com are dishing out the dirt. Do you have a confession? Please comment!
This is what got us started: here's an interesting forum post we had from a very zealous but graciously honest energy-modeler:
I have to be 100% honest here. I have a very general lust for sports cars but more specifically for older American...
