An assessment of the 1977 NM Energy Conservation Code was performed to identify changes which were cost effective in terms of life-cycle cost to the building owners. Suggestions were made to upgrade the residnetial sections of the code (apartments and multi-, single-family dwellings) to current practice (i.e., double pane windows, R-11 walls, and R-19 roof). For commercial buildings, it was recommended that a lighting power density be implemented at 2.0 Watts per square foot in office and retail structures. Implementation of the recommendations was estimated to save 4.75 million annually in utility costs over the present Code.
