International. ASHRAE presents these days a new standard focused on the creation of energy models establishing the minimum requirements to provide assistance in the design of buildings through the simulation and analysis of the energy consumption of the building.
ASHRAE members have been working on this standard for more than five years. On June 24, as part of the ASHARE Annual Conference to be held in Houston, a seminar on the new standard will be organized.
The ANSI/ASHRAE 209-2018 standard, Energy Simulation Assisted Design for Buildings Except Low-Rise Residential Buildings, was created to define reliable and consistent procedures that advance the use of timely energy models to quantify the impact of design decisions at the very moment they are being developed.
Applying to new buildings and rehabilitations, the standard defines the nominal requirements for using modeling in integrated design, describing analysis activities from early concept development to subsequent occupancy.
Design, construction and operation of the building
The standard defines seven modeling cycles in the design phase. Each has specific modeling goals coordinated with the typical design process and is an extension of an overall modeling cycle that can be applied at any time during design.
Three additional modeling cycles are defined for the construction and operation phases, and include a comparison of design and occupancy performance, to help owners and designers understand the impact of modeling hypotheses on the design phase and assist in future modeling.
To minimally comply with Standard 209-2018, project teams must evaluate energy efficiency options using an early modeling process during the design process (schematic design).
ASHRAE members have been working on this standard for more than five years. The Standard 209 committee was formed in the spring of 2011, and the first committee meeting was held during the 2012 ASHRAE Annual Conference in San Antonio, Texas.
