What does the 2012 International Energy Conservation Code mean for the construction industry?

Internationally, code officials recognize the need for a modern, up-to-date energy conservation code addressing the design of energy-efficient building envelopes and installation of energy efficient mechanical, lighting and power systems through requirements emphasizing performance.

What is energy compliance method?

Compliance based. on simulated energy performance requires that a proposed residence (proposed design) be shown to have an annual energy cost that is less than or equal to the annual energy cost of the standard reference design. 46. Page 47.

What is the latest International Energy Conservation Code?

Introduction. ​The International Energy Conservation Code®(IECC®) establishes minimum requirements for energy-efficient buildings using prescriptive and performance-related provisions. It is founded on broad-based principles that make possible the use of new materials and new energy-efficient designs.

What is prescriptive energy code compliance?

A prescriptive code requires that each component is built to a certain standard, e.g. Wall R-value at least 20. A performance code requires that the building as a whole performs to a certain standard, e.g. uses less energy than the same building built to prescriptive code.

What is a performance based code?

Performance-based (also known as outcome-based) codes set standards based upon buildings’ actual energy use, rather than on compliance with stipulated technology or design features.

How many states have adopted the IECC?

48 states
The IECC is in use or adopted in 48 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands.

What is the difference between a prescriptive and a performance code?

What is the difference between mandatory and prescriptive?

What is the difference between Prescriptive and Mandatory measures? Prescriptive measures are the values of the standard package A in that climate zone – it is also the design of the baseline building; mandatory measures have to be meet no matter what.
