Software screen captures and equations

Software

Software developed by EETD researchers for energy-efficient buildings, and electricity grid. Download free or for a nominal licensing fee.

EETD scientists develop software to help design more energy-efficient buildings, audit energy use in buildings, examine the economics of sustainable projects, and model components of building systems. Most EETD software and documentation is available for download and public use.

Building Controls Virtual Test Bed

The Building Controls Virtual Test Bed (BCVTB) is a software environment that allows expert users to couple different simulation programs for co-simulation, and to couple simulation programs with actual hardware.

Demand Response Quick Assessment Tool (DRQAT)

The opportunities for demand reduction and cost saving with building demand responsive control vary tremendously with building type and location. This assessment tool will predict the energy and demand saving, the economic saving, and the thermal comfort impact for various demand responsive strategies. It is based on the most popular feature and capabilities of EnergyPlus. Users of the tool will be asked to enter the basic building information such as types, square footage, building envelope, orientation, utility schedule, etc.

DER-CAM

The Distributed Energy Resources Customer Adoption Model (DER-CAM) is a techno-economic model of customer DER adoption. Users input market information (fuel prices), system load information (hourly enduse loads), and DER technology information (costs, performance data, etc) and DER-CAM outputs the optimal selection of technologies, e.g. PV, solar thermal or CHP that should be adopted and details how they should be operated based on the specified inputs. Other outputs also include CO2 emissions.

Design Intent Tool

This tool helps building owners, architects, and engineers develop a Design Intent Document to help facilitate record-keeping and ensure that the owner's and designer's vision and goals are achieved and periodically verified through performance measurement. The focus is on energy-efficiency, but the tool is applicable to any aspect of design.

DOE-2

An advanced computer program that simulates hourly building energy use. This program is an international benchmark and is used as the basis of building standards in the U.S. and other countries. DOE-2 is also the basis of numerous handbooks on energy-efficient buildings and building components. Many design and consulting firms use DOE-2 as the main engine of their services.

Home Energy Saver for Consumers

The Home Energy Saver™ (HES) empowers homeowners and renters to save money, live better, and help the earth by reducing energy use in their homes. HES recommends energy-saving upgrades that are appropriate to the home and make sense for the home's climate and local energy prices. The money invested in these upgrades commonly earns "interest" in the form of energy bill savings, at an annual rate of 20% or more.

Metracker

Metracker is a prototype computer tool designed to demonstrate the specification, tracking, and visualization of building performance objectives and their associated metrics across the complete life cycle of a building. The underlying concept is that, to better assure the intended performance of a building, it is necessary to establish a baseline for expected performance and periodically compare actual performance to this baseline.
