Energry and Resource Conservation
Term | Definition |
---|---|
Environmentally Sound Development | disturbs existing site as little as possible: adaptive reuse, redevelopment of disturbed sites, use existing infrastructure |
Site Analysis and Assessment | Climate, Solar Altitude and Solar Access, Wind Patterns, Topography, Soil Characteristics, Groundwater and Run-off, Vegetation, Adjacent Land Use, Circulation, Utilities |
Solar Altitude and Solar Access | Building orientation, passive solar for heating, lighting, and photovoltaics |
Climate | Plan for microclimates |
Wind Patterns | Avoid damming cold-moisture air or blocking cool breeze |
Topography | Building proportions, wind patterns, drainage strategies, gravity-fed lines |
Soil Characteristics | Texture and load-bearing capacity, footings, and erosion |
Vegetation | Plant communities, run-off, and solar access |
Main goal of Site Development | Minimize energy and resource consumption during construction and occupation |
5 Steps to guide initial conceptual design | 1. Area takeoffs of impervious surface (>20% requires mitigation) 2. Alternative designs to minimize resource cost 3. Topo/hydro impacts (cut/fill, erosion, siltation, groundwater, pollution) 4. Development and maintenance costs 5. Compatibility Index |
Minimize transportation needs | Develop near amenities, include amenities, support alternative trans, consolidate trans networks |
Utilities | Locate development in or adjacent to existing, use gravity, consolidate corridors |
Building orientation | Solar access and align with landscape contours |
Construction methods and materials | eliminate unnecessary site disruption, use recycled or regionally available materials, albido affect |
Bioclimatic Design | relating temperature and humidity conditions to design for human comfort |
Plateau | Hot/Arid: balance extremes, shelter |
High Slope | Cold: control wind and promote solar gain |
Low Slope | Temperate: strategic wind and sun by seasons |
Bottom land | Hot/Humid: air movement |
Hot-Arid Region | Moisture conserving plants, prevent heat build-up, deflect hot winds, trap cool air, favor eastern slope base |
Temperate Region | Promote shade and evaporative cooling in warm season, block wind (NE/NW) and promote heat gain in cool season, favor southeast military crest |
Hot-Humid Region | Maximize breeze, shade, high ceilings, favor top of eastern slope |
Human Comfort Temperature | 68-80 degrees Fahrenheit |
Human Comfort Humidity | 80-20% |
Human Comfort Wind Velocity | 28 MPH |
Cold Regions | Control winter winds, promote solar gain and storage, favor south-southwest mid of slope |
