OPEN SPACE
OPEN SPACE, AND NATURAL RESOURCES OBSERVATIONS COURTHOUSE SQUARE HAS SEVERAL PARKS AND PUBLIC PLAZAS WITHIN A 10 MINUTE WALKING RADIUS OF METRO. THEY ARE DIVERSE IN SCALE AND IN USE. IT IS IMPORTANT TO DEVELOP A DESIGN FOR COURTHOUSE SQUARE THAT ADDS VALUE TO THE COUNTY AND THAT COMPLEMENTS EXISTING AMENITIES. WE HAVE AN OPPORTUNITY TO DEVELOP A CIVIC OPEN SPACE THAT IS MORE GRAND IN SCALE THAN ANY OTHER SPACE IN THE AREA.
OPEN SPACE, AND NATURAL RESOURCES: RECREATION AND PLAY 1.

9. COLONIAL OFFICES METRO PLAZA METRO ENTRY AND CAPITAL BIKE SHARE DOCK PARTIALLY PAVED WITH MINOR FOLIAGE
10. THE “PORK CHOP” MEDIAN EMPTY W/ MINOR FOLIAGE SLATED FOR ADJUSTMENT
OPEN SPACE, AND NATURAL RESOURCES: TOPOGRAPHY CHALLENGES 1. SITE ELEVATIONS DROP OFF DRAMATICALLY TO THE SOUTH AND EAST OF THE COURTHOUSE SQUARE SITE. THIS POSES CHALLENGES TO THE WALKABILITY FROM ROSSLYN AND THE RESIDENTIAL BLOCKS TO THE SOUTH. 2. AS A PLATEAU, IT STANDS PROMINENTLY BUT DISTINCTLY SEPARATE FROM IT’S SURROUNDINGS.
OPEN SPACE, AND NATURAL RESOURCES: TOPOGRAPHY OPPORTUNITIES 1. AS A PLATEAU, IT STANDS PROMINENTLY ABOVE ITS SURROUNDINGS AND HAS ADVANTAGEOUS SEE AND BE SEEN QUALITIES. 2. THE STUDY AREA HAS SIGNIFICANT TOPO VARIATION FROM NORTH TO SOUTH 3. THE SITE HAS LAYERS OF METRO LANDINGS DIRECTLY ADJACENT TO THE NORTH AND WEST END OF THE STUDY AREA 4. THE METRO MEZZANINE CONNECTS TO UNDERGROUND PARKING, THE AMC THEATRE AND IS APPROXIMATELY THE SAME LEVEL AS VERIZON PLAZA
SUSTAINABILITY
SUSTAINABILITY SUSTAINABILITY FRAMEWORK A SUSTAINABILITY FRAMEWORK IS A TOOL THAT PROVIDES:
SUSTAINABILITY FRAMEWORK SYSTEM
•
A MEANS TO DEFINE SUCCESS
•
AN ORGANIZATIONAL STRUCTURE
•
COLLECTION OF GOALS, OBJECTIVES, AND INDICATORS THAT DRIVE THE DESIGN, CONSTRUCTION, AND OPERATIONS PROCESS TOWARDS SUSTAINABILITY
•
GOALS AND OBJECTIVES ARE DEFINED THROUGH A MULTI-STAKEHOLDER AND MULTI-DISCIPLINED APPROACH
•
A UNIQUE CONCEPTION OF SUSTAINABLE DEVELOPMENT TAILORED TO THE PROJECT CONTEXT
•
DEVELOPED ALONGSIDE THE OVERALL ENGINEERING AND ARCHITECTURAL AND URBAN DESIGN, ALLOWING FEEDBACK AND RELATING TO THE ORIGINAL PROPOSAL TO THE ORIGINAL PROJECT GOALS AND OBJECTIVES WHILE ADVANCING IN DETAIL
•
THEY OFTEN UTILIZE STANDARDIZED ASSESSMENT TOOLS TO CLEARLY DEFINE DEFENSIBLE PERFORMANCE GOALS FOR SECTORS WITHIN THE OVERALL PROJECT
DISTRICT ENERGY NETWORKS/STORMWATER MANAGEMENT DISTRICT ENERGY NETWORKS: PROGRESS SUMMARY 1. ENERGY EFFICIENCY MEASURE •
ECONOMIC CALCULATORS HAVE BEEN DEVELOPED FOR USE IN APPRAISING MEASURES THAT ARE DEPENDED ON ENERGY, COST, AND CARBON REDUCTION STRATEGIES
2. DEVELOPMENT OF DYNAMIC THERMAL MODELS HAS BEEN INITIATED •
SPECIFIC BUILDING INFO AND DATA CAPTURED DURING VISIT WILL INFORM THE PRIMARY BUILDING GEOMETRY AS WELL AS SECONDARY BUILDING GEOMETRY (OUTSIDE PROJECT BOUNDARY) SECONDARY BUILDING GEOMETRY WILL BE USED TO ASSESS THE DISTRICT BOUNDARY INFLUENCE
3. UTILITY CONSUMPTION DATA HAS BEEN PROCESSED •
MEASURED ENERGY USAGE OF THE BUILDINGS AND IT’S SYSTEMS ARE USED TO ADJUST THE INPUT PARAMETERS OF THE DYNAMIC SIMULATION MODEL

5. OPTIMIZATION OF THERMAL AND ELECTRICAL ENERGY STUDY •
RESOURCE ALLOCATION FROM THE ENERGY CONVERSION OF A COMBUSTIBLE FUEL IN A COOLING, HEATING, AND POWER SYSTEM, IS DEPENDENT UPON THE APPRAISAL OF THE PREDICTIVE LOAD DURATION CURVE. THE DYNAMIC SIMULATION MODELS BETTER CHARACTERIZE THE LDC THROUGH THE TIME USE OF TIME-STEP INTERVALS THAT CONSIDER VARYING ENVIRONMENTAL FACTORS
6. BUILDING ENERGY USE INTENSITIES •
THE BUILDING ENERGY USE INTENSITIES WILL BE BENCHMARKED AGAINST BUILDINGS WITH SIMILAR PROFILES (SEE ADJACENT CHART)
