ASHRAE 189.1 is a standard for the design of high-performance green buildings that covers various aspects of sustainability, energy efficiency, water efficiency, indoor environmental quality, and more. It is an alternate compliance path for the IGCC, which is a model code that contains minimum requirements for green building design and construction. In jurisdictions that adopt the IGCC, a builder has the option to design and construct a building in accordance with the provisions of ASHRAE 189.1 rather than those of the IGCC123.

Recycling is the term for collecting, reprocessing, marketing and using materials that are diverted or recovered from the solid waste stream. Recycling is a process that transforms waste materials into new products that can be used for different purposes. Recycling reduces the amount of waste sent to landfills or incinerators, conserves natural resources, saves energy, and reduces greenhouse gas emissions. The LEED Green Associate Candidate Handbook states that one of the intents of the Materials and Resources category is to “reduce waste through recycling during construction and occupancy” [1, p. 15]. References: LEED Green Associate Candidate Handbook, [Recycling Basics | U.S. Environmental Protection Agency]

According to the Indoor Environmental Quality credit category of LEED, mechanical and electrical rooms are considered unoccupied spaces. These spaces are typically not intended for human occupancy, except for maintenance or operational purposes, and therefore do not require the same level of environmental control (such as ventilation or temperature control) as occupied spaces. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
