ROOF TRUSS CONSIDERATIONS Information Used In Analysis

Roof Structure Standard Roof Sizes Tiles Factor of Safety Used No attic necessary

Solar Panels Most efficient between 30-40° Each weighs around 80 lbs Could have up to 4 solar panels Each solar panel has a surface area of 4ft x 6ft

Environment .2” of snow fall is the maximum ever recorded Winds could reach up to 206 mph (F3 tornado) Montgomery County has had 15 tornadoes since

1956

ROOF TRUSS LIMITS Beam Forces

Maximum bending stress of material is 1650 lbs/ft² Maximum compressive stress is 1700 lbs/ft²

Forces on trusses Flat Plate Collectors

F=3.33lbs/ft² Forces in the negative y-direction

Plywood F=2.15625 lbs/ft² Force in the negative y-direction

Shingles F=.304 lbs/ft² Force in the negative y-direction

Wind F=.00256V² F=102.4 lbs/ft² Force in the x-direction

ROOF TRUSS DATA COLLECTION

Factor of Safety (FOS) turns out to be 4.7 Beam Loading(2”x12”)

Compressive loading failure is 24225 lbs Bending moment failure is 313680 lbs-inches

Worst Case Scenario Calculations Compressive load is 546.465 lbs Bending moment is 66667 lbs-inches

SOLAR WATER HEATING SYSTEMS

Hydronic System Analysis

Closed loop – Active system Potable water routed to storage tank Working Fluid circulates through collectors Potable water is heated through heat

exchanger System requires auxiliary components like

expansion tank, valves, etc.

Page 12: PDR PRESENTATION

BASIC ILLUSTRATION

Page 13: PDR PRESENTATION

MAJOR COMPONENTS ANALYZED

analysis & selection of suitable pump selection of appropriate heat exchanger selection of main water storage tank. primary plumbing components – pipes

For Each: options, benefits and costs analyzed

Page 14: PDR PRESENTATION

HYDRONIC SYSTEM PUMP ANLAYSIS

How the analysis was carried out :

1. Design analysis was based on Architectural & Solar Thermal systems & options were considered

2. Architectural: basement & overall house dimensions

3. Solar Thermal: two possible options of Flat Plate Collectors with varying flow rates, dimensions and pressure losses.

4. Result of Total System Head Loss :

No. of FPC’s
