Large Scale Building Energy Simulations

Large Scale Building Energy Simulations

Energy simulation is an essential component to estimating savings of energy standards or energy efficiency programs. Using multiple prototypes along with a list of energy efficiency measures, we use energy modeling software to predict the savings benefits of energy codes or standards across a wide range of building types and climate regions. These projects often require tens of thousands of energy simulations to estimate savings across a population of buildings. Madison Engineering uses large scale energy modeling and analysis to assist government agencies and environmental policy groups develop energy efficiency programs, codes and standards

Sample projects:

California Database of Energy Efficiency Resources:

The Database of Energy Efficiency Resources (DEER) is considered one of the most comprehensive compilations of energy savings and calculation methods. Included in DEER are thousands of savings impacts for hundreds of different energy efficiency measures. Madison Engineering has been a contributor to DEER for more than 15 years and has used large scale energy modeling to developed savings estimates for utility efficiency program including lighting efficiency measures such as LEDs and HVAC measures such as high-efficiency water chillers.

Impact of Code Compliance in Rhode Island and Massachusetts:

For the New Buildings Institute, Madison Engineering used energy modeling to estimate the benefits of improvements to energy codes in Rhode Island and Massachusetts. We used field data from newly constructed buildings to determine levels of over- and under-compliance, then translated those compliance levels into energy modeling inputs. These were then simulated as well as different code baseline models.  The results of the simulations were then analyzed and processed to estimate the performance of existing buildings to the state’s energy code.

Core Performance Construction Guidelines:

We created several energy model prototypes and simulated many energy efficiency measures for locations all across the United States. The results of the simulations were used to create NBI’s Core Performance Guide.
