Energy Analysis |
| |
Energy analysis is a very useful tool in estimating building life cycle costs and is becoming more and more important to facility managers and owners early on in the design process. The tool gives us the ability to predict building energy use. By making design changes to the model and running a series of energy analyses based on the various design iterations, we are able to estimate the build-ing’s loads based on the design schemes, thereby helping to minimize energy use and overall life cycle costs.
In its current incarnation, Revit Architecture will not provide energy analysis. The software is primarily created for architects to model and document their designs; you’ll need to use one of the third-party applications discussed in the following pages. At the same time, the design of a building involves not only its function, but also its aesthetic and social implications as well as its environ-mental impact. Today, the focus on energy efficiency is becoming more and more important to stakeholders involved with architecture. Owners and facilities managers alike are increasingly looking to get up-front data on predicted energy footprint and short-term and long-term costs and other information at the early stages of design.
Energy modeling can involve a complex set of analytical calculations, and entire careers are based on deriving accurate and predictable results. This type of analysis can encompass building energy use, daylighting, alternative power sources, computational fluid dynamics, thermal gain, and carbon footprint, to name a few. Essentially, energy modeling allows you to understand the building from a more holistic, ecological point of view.
It is important to keep in mind that any value you get out of the Revit model with respect to energy analysis will be only as useful as the information you have been able to put into the model. Good input will lead to good output.
There are a couple of applications that can be used in unison with the Revit architectural model for additional energy analysis data. |
