Architectural First Floor Black band lives here!

Architectural Second Floor Black band lives here!

Architectural Basement? Initial research showed that few houses in New Mexico are built with basements, due to poor soil conditions Further research into the soil conditions, using has shown that almost half of the soil in the Albuquerque area would not be a limiting factor as far as basements are concerned Thus, further consideration shall have to be taken as far as the basement situation is concerned Additionally, both floors need windows added to them Black band lives here!

Foundation Compression due to House According to the International Residential Code, the live load varies from about 20 to about 60 pounds per square foot ≈ 40psf First Floor: 40 psf Second Floor: 30 psf Roof: psf ≈ 40psf All units then converted to metric, for consistency Produced the following table: Black band lives here!

Foundation Compression due to House Black band lives here! For concrete : 3,500 psi = kg/m 2 For cinder blocks : 2,200 psi = kg/ m 2

Foundation Force Caused by Soil Frost line Depth = 9’’ =.2286 m Minimum Footing Depth = 6’’ Below Frost line = 15’’ =.381 m If a basement is feasible, depth = 8’ = 2.44 m Had difficulty finding a specific soil density, instead just found a large range of densities Created the following table, displaying the force caused by the soil, as a function of soil depth and soil density Black band lives here!

Foundation Force caused by Soil Black band lives here!

Foundation Bending stress Caused By Soil Columns in yellow: minimum depth and “basement” depth From here moments and bending stresses caused by these forces can be determined Based on prior knowledge, it is already known that rebar will be necessary For now.2302 m is used as a thickness Black band lives here!

Foundation Bending Stress Caused By Soil Black band lives here!

Foundation What's Next From here I need to determine if any of these will give the desired factor of safety Assuming they won't, I'll need to determine amount of rebar required –Can also determine if the thickness can simply be increased A cost comparison should also take place Check to see if any pros/cons from one type significantly outweigh others Black band lives here!

Hydronic System Analysis System Schematic Transports fluid between FPCs and Storage Tank Appropriate pump, valves and piping are to be chosen given an array of FPCs

Hydronic System Analysis Calculations With 5 FPCs Max head = ft Pipe Diameter= 1.5” Flow Rate = 20gpm With 10 FPCs Max head = ft Pipe Diameter= 2.0” Flow Rate = 40gpm

Hydronic System Analysis Pump Selection Cost with 5 FPCs $ Cost with 10 FPCs $ Both cases require similar head 10 FPCs requires a greater flow rate

Hydronic System Analysis Valve Selection Gate and Ball valves Minimal pressure drop Good for on/off applications Globe Valve Creates some pressure drop Good for regulating flow

Hydronic System Analysis Piping materials CPVC Cheap Self-insulated Lightweight Easy to work with Can become brittle and discolored when exposed to UV rays PVC Shares many of the upsides of CPVC Not suitable for hot water usage Copper Proven durability Fire resistant Requires skilled labor to install/repair Galvanized Steel High durability Expensive Very difficult to repair

Hydronic System Analysis Piping Costs Copper 1.5” Diameter $94.76 per 10 ft 2.0” Diameter $ per 10 ft CPVC 1.5” Diameter $42.45 per 10 ft 2.0” Diameter $58.76 per 10 ft
