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. ROCKY RUN PARK: • MULTI USE FIELDS• 2 BASKETBALL/TENNIS COURTS• PLAYGROUND W/SEATING

2. KEY ELEMENTARY FIELDS AND PLAYGROUND• SOCCER FIELD/SOFTBALL FIELD• PLAYGROUNDS

4. WILSON APARTMENTS PARK• SEATING• TREE SHADED GRASS SPACE

OPEN SPACE, AND NATURAL RESOURCES:PRIVATELY OWNED PARKS

3. BARTON PARK AND COMMUNITY GARDEN• GREENSPACE, SEATING, SHADE• COMMUNITY GARDEN

4. CLARENDON BOULEVARD ALCOVE• TREE SHADED SEATING• PAVED SURFACE

OPEN SPACE, AND NATURAL RESOURCES:PRIVATELY OWNED PUBLIC PLAZAS

3. VERIZON PLAZA• MULTIPLE LEVELS WITH SEATING• PUBLIC ART AND FOLIAGE

OPEN SPACE, AND NATURAL RESOURCES:PUBLIC PLAZAS

7. COURTHOUSE PLAZA• PAVED PLAZA WITH ACTIVE FRONTAGE• SHADED SEATING AND ACTIVE FOUNTAIN

8. JUDICIAL PLAZA• STEPPED PAVED PLAZA WITH MINOR SEATING• MEMORIAL SCULPTURE & VIEW OF GW MONUMENT

OPEN SPACE, AND NATURAL RESOURCES:MISCELLANEOUS PUBLIC SPACE

11. COURTHOUSE PARKING LOTACTIVE WITH MARKETS ON WEEKENDS2 SHADE TREES WITH SEATING AND 3 HISTORIC MARKERS

9. COLONIAL OFFICES METRO PLAZAMETRO ENTRY AND CAPITAL BIKE SHARE DOCKPARTIALLY PAVED WITH MINOR FOLIAGE

10. THE “PORK CHOP” MEDIANEMPTY 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 FRAMEWORK

A SUSTAINABILITY FRAMEWORK IS A TOOL THAT PROVIDES:

• 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

DISTRICT ENERGY NETWORKS/STORMWATER MANAGEMENT

DISTRICT ENERGY NETWORKS: PROGRESS SUMMARY

4. ENERGY END USE BREAKDOWNS OF THE EXISTING BUILDINGS

• CALIBRATED FROM THE DYNAMIC THERMAL MODELS• THE BUILDINGS ANNUAL ENERGY USE BREAKDOWN FOR

MAJOR MECH, ETC. WILL BE ANALYZED TO ASSESS THE VIABILITY OF CERTAIN ENERGY DESIGN SYSTEMS

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)

STORMWATER MANAGEMENT

STORMWATER OBSERVATIONS

1. SYSTEM WIDE CONCERNS• EXISTING INFRASTRUCTURE UNDER PRESSURE

(ADDITIONAL CAPACITY REQUIRED FOR 30% OF SYSTEM)

• ONGOING EROSION OF COUNTY STREAMS• NEW AND EVOLVING STORMWATER REGULATIONS

AND ONEROUS POLLUTION TARGETS• PREPARING FOR CLIMATE CHANGE IMPACTS

2. HIGH SITE ELEVATION• COURTHOUSE SQUARE IS ON TOP OF A

PROMONTORY; MANAGING STORMWATER RUNOFF IS IMPORTANT TO MITIGATE DOWNSTREAM IMPACTS INCLUDING EROSION AND NUTRIENT AND SEDIMENT REDUCTION

3. HIGH LEVEL OF IMPERVIOUS SURFACES• FEW EXISTING OPPORTUNITIES FOR STORMWATER

TO INFILTRATE• (ASSUMED) RELATIVELY HIGH RATE OF

STORMWATER RUNOFF• (ASSUMED) RELATIVELY HIGH LEVEL OF

SEDIMENT/NUTRIENT RUNOFF

4. MINIMAL RECYCLING AT THE BUILDING SCALE• POTENTIAL OPPORTUNITIES TO RECYCLE WATER

FOR NON-POTABLE USES SUCH AS COOLING TOWER MAKEUP AND LANDSCAPE IRRIGATION
