(1) Draft Revision of MIL-HDBK-1190, Facility Planning and Design Guide,
Chapter 8, Energy Conservation Criteria
1. Purpose. To provide best available current interim technical guidance concerning use of
lowest life cycle costs and reduced Design Energy Target (DET) values to achieve mandated
energy standards. Although not mandatory for projects currently under design, this interim
technical guidance may be used for current projects on a case-by-case basis where it does not
impact execution or exceed project scope and budget.
2. Background. Reference (a) provides goals to reduce facilities energy consumption, and states
policy to improve the management of Navy energy consumption. Executive Order No. 12902
mandates a 30% reduction of the 1985 energy usage by the year 2005 vice the 20% reduction by
the year 2000 required by 10 CFR 435 and previous Executive Order No. 12759.
It also directed the Interagency Energy Management Task Force to determine applicable energy
performance standards to be met or exceeded. Reference (b) provided interim guidance to use
energy efficient designs and products, to provide facilities with the lowest life cycle costs, and
to continue to use the Design Energy Targets in enclosure (1) of reference (c) as minimum
standards until the Task Force set new ones. However, the Task Force still has not issued any
guidance, and it is prudent to set some reasonable DETs to ensure the Navy facilities meet
mandated energy conservation standards.
Facilities and projects designed only to meet, not exceed, the current Design Energy Targets will
adversely affect the Navy's efforts to meet the 2005 goal of 30% energy reduction. Advances in
the efficiency of energy consuming equipment such as lighting products result in cost effective
facility designs having energy consumption levels lower than the Design Energy Targets.
