The Sustainable Buildings Industry Council (SBIC) has released Version 1.8 of its award-winning ENERGY-10 TM software. The software now includes a tool for building designers to integrate photovoltaics and solar domestic hot water in an energy efficient building. SBIC notes these solar features were added to ENERGY-10 TM Version 1.8 at the urging of the solar industry.
For TFM’s coverage of this topic, see “Sustainable By Design” in the archives.
New features in Version 1.8 include:
• A photovoltaic module that provides the ability to model and simulate the performance of a PV system that is either stand-alone or integrated with the building.
• A solar domestic hot water module provides a new solar domestic/service hot water modeling capability.
• A new library (“ASHRAELIB”) is included defining constructions (wall, roof, window, etc.) as spelled out in ASHRAE 90.1-2004.
SBIC notes that thousands of building designers and students currently use ENERGY-10 TM to make informed decisions about the energy performance of the smaller commercial buildings and homes they are designing. The software helps identify the best combination of nearly a dozen energy efficient strategies, including daylighting controls, passive solar heating, and high efficiency mechanical systems. According to SBIC, it usually takes less than an hour at a project’s outset to produce a simulation, which can result in energy savings of 40-70%.
Norm Weaver, a professional engineer from Steamboat Springs, CO, involved in the development of ENERGY-10TM since 1999, says, “Among the many updates in Version 1.8, the biggest feature is the introduction of integrated PV and Solar DHW modeling. With the growing interest in ‘net zero’ buildings, ENERGY-10TM can be used to rapidly close in on workable alternatives.”
Some highlights of ENERGY-10 TM are that it:
• Allows the user to integrate and assess dozens of energy efficient design decisions quickly and accurately.
• Quantifies and clearly illustrates the impact of design decisions on first cost, operating costs, and pollution prevention.
• Helps the user obtain energy credits under the U.S. Green Building Council’s LEED™ program. Output reports for “daylighting” and “total building energy use” facilitate the LEED™ submission process.
• Has multiple levels of technical support, including free or hourly direct support for professionals seeking assistance with beginning through advanced simulations, and SBIC’s free ENERGY-10 TM NetForum, which allows users to discuss the program and share ideas.
ENERGY-10TM Version 1.8 is now available for purchase online through SBIC. Upgrades, academic and professional site licenses are also available for purchase on-line.
