LEED® Rating
Most capital projects with an estimated construction cost of $2,000,000 or more involving the construction of a new building, addition to an existing building, or the substantial reconstruction of an existing building, across most occupancy groups, are required to be designed and constructed to achieve a LEED® gold or higher rating, or other alternative green building standards.
Low Energy Use Intensity Building
Across most occupancy groups, similar city-owned projects are required to be designed as a low energy intensity building. A low energy intensity building is one designed and constructed such that its energy use intensity is the less stringent of the following;
(1) 50 percent of the design energy intensity of the more stringent of (a) the median source energy use intensity for contemporary buildings according to benchmarking data or (b) standards established for similar buildings according to ASHRAE 90.1-2013.
(2) A source energy use intensity of 38 kBTU/yr per square foot of floor area and for additions to, or substantial reconstructions of, existing buildings, a source energy use intensity of 42 kBTU/yr per square foot of floor area.
Energy Cost Reductions
Non-city owned projects (or city-owned projects without an envelope scope) estimated construction costs of $12,000,000 or more are required to reduce energy costs to by 20 percent. Projects with an estimated budget of $30,000,000 must reduce energy costs by 25 percent. Energy cost must be reduced by an additional five percent if it the payback on such investment through savings in energy cost would not exceed seven years.
System Installations or Replacements
Capital projects that solely involve or include a system upgrade, are subject to specific requirements, dependent upon the type of project and the estimated installation or replacement cost.
Boiler $2,000,000 or more 10 percent
Lighting $1,000,000 or more 10 percent
HVAC $2,000,000 or more 5 percent
Plumbing Systems Each project involving the installation or replacement of plumbing systems at an estimated construction cost for such of $500,000 or more must reduce potable water consumption in the aggregate by a minimum of 30 percent, pending approval of waterless urinals.
