Ch. 597

25D.

FOR THE PURPOSE OF EVALUATING LIFE-CYCLE COSTS THE
DEPARTMENT SHALL ESTABLISH AND UNIFORMLY APPLY A DEFINITION
OF WHAT CONSTITUTES THE LIFE OF A BUILDING. THE DEPARTMENT
SHALL ALSO SUPPLY DEFENDING CRITERIA FOR THE SELECTION OF
THE DEFINITION.

25E.

(A)    THE DEPARTMENT SHALL ESTABLISH STANDARDS AND
PROCEDURES, INCLUDING ENERGY CONSERVATION PERFORMANCE
GUIDELINES FOR EVALUATING THE EFFICIENCY OF DESIGNS FOR ALL
PROPOSED STATE-FINANCED AND STATE-ASSISTED BUILDING
CONSTRUCTION. THESE STANDARDS AND PROCEDURES SHALL TAKE
EFFECT BY MARCH 1, 1979.

(B)    THE LIFE-CYCLE COSTS SHALL BE THE SUM OF:

(1)    THE REASONABLY EXPECTED FUEL COSTS OVER THE
LIFE OF THE BUILDING, AS DETERMINED BY THE DEPARTMENT, THAT
ARE REQUIRED TO MAINTAIN ILLUMINATION, POWER, TEMPERATURE,
HUMIDITY, VENTILATION, AND ALL OTHER ENERGY-CONSUMING
EQUIPMENT IN A BUILDING; AND

(2)    THE REASONABLE COSTS OF PROBABLE
MAINTENANCE, INCLUDING LABOR AND MATERIALS, AND OPERATION OF
THE BUILDING.

(C)    TO DETERMINE THE LIFE-CYCLE COSTS AS DEFINED IN
SUBSECTION (B), THE DEPARTMENT SHALL ESTABLISH STANDARDS
THAT SHALL INCLUDE, BUT NOT BE LIMITED TO:

(1)    THE ORIENTATION AND INTEGRATION OF THE
BUILDING WITH RESPECT TO ITS PHYSICAL SITE, IF WIND OR SOLAR

ENERGY IS TO BE EMPLOYED;

(2)    THE AMOUNT AND TYPE OF GLASS EMPLOYED IN
THE BUILDING AND THE DIRECTIONS OF EXPOSURE;

(3)    THE EFFECT OF INSULATION INCORPORATED INTO
THE BUILDING DESIGN AND THE EFFECT ON SOLAR UTILIZATION OF
THE PROPERTIES OF EXTERNAL SURFACES;

(4)    THE VARIABLE OCCUPANCY AND OPERATING

CONDITIONS OF THE BUILDING AND SUBPORTIONS OF THE BUILDING;
AND

(5)    AN ENERGY CONSUMPTION ANALYSIS OF THE MAJOR
EQUIPMENT OF THE BUILDING'S HEATING SYSTEM, VENTILATION
SYSTEM, COOLING SYSTEM, LIGHTING SYSTEM, HOT WATER SYSTEM,
AND ALL OTHER MAJOR ENERGY-CONSUMING EQUIPMENT AND SYSTEMS
AS APPROPRIATE. THIS ANALYSIS SHALL INCLUDE:

(I) THE COMPARISON OF ALTERNATIVE ENERGY
SYSTEMS, EACH OF WHICH UTILIZES THE MOST PLENTIFUL AND
AVAILABLE ENERGY RESOURCES IN COMBINATIONS WHICH RESULT IN
GREATEST ENERGY EFFICIENCY BOTH IN THE BUILDING AND AT THE
