What started as a discussion on BLDG-SIM many years ago is
now an ASHRAE standard. See below.

*ASHRAE Publishes Energy Simulation-Aided Design Standard**
*/-- //Standard 209-2018 defines minimum requirements for
integrating building energy modeling into the design process


*ATLANTA (April 24, 2018)*? ASHRAE published a new standard
describing a methodology to apply building energy modeling
throughout the design process.

ASHRAE Standard 209-2018, Energy Simulation Aided Design for
Buildings except Low Rise Residential Buildings,
minimum requirements for providing energy design assistance
using building energy simulation and analysis.

The standard defines consistent energy modeling procedures
to quantify the impact of design decisions when they are
being made. To minimally comply with Standard 209-2018,
building project teams must evaluate energy-efficiency
options using modeling early in the design process
(schematic design).

?For many buildings, energy modeling is typically employed
only near the end of the design process to determine if a
building meets minimum requirements for energy-efficient
design, outlined in Standard 90.1,? said Jason Glazer, chair
of the Standard 209 committee. ?Standard 209-2018 requires
building energy modeling earlier in the design process, so
the information it provides will more effectively inform
design decisions and result in higher performing buildings.?

This new standard will be useful to building owners,
architects, government agencies and many others who want
their projects to benefit from the use of simulation. By
referencing the standard, they can identify appropriate
modeling tasks and procure modeling services that add value
in the design process.

The standard also describes analysis activities from early
concept development to post-occupancy. The standard applies
to new buildings, major renovations and additions, and
defines nominal requirements for using modeling to support
integrated design efforts.

Standard 209-2018 defines seven design-phase modeling
cycles, each with specific modeling goals coordinated with
the typical design process. Each modeling cycle is an
extension of a general modeling cycle that can be applied
any time during design. Three additional modeling cycles are
defined for construction and operation phases, and include a
design and post-occupancy performance comparison to help
owners and modelers understand the impact of design phase
modeling assumptions and inform future modeling efforts.

The cost of ASHRAE Standard 209-2018 is $67 for ASHRAE
members ($79, non-members). To order, visit

Congratulations, Jason (and the rest of the committee)
