- Laurie Catey's Questions
- Dimensions of the floor of the buildings (area and wall exposures)
- Historic Building Area = 115ft (S/N) x 76ft (E/W)
- New Addition Building Area = 65ft (S/N) x 42 ft (E/W)
- Height of walls/roof and at center monitor
- Historic Building = Wall height = 14.5 ft / Center of Roof Height = 23 ft
- New Addition = Wall Height = 15 ft
- Amount of windows (estimate of % of wall that is window would be fine at this point along with an idea of which exposure the % goes with)
- Historic Window-to-Wall Ratio = 27% (E/S/W) (Assume 0% for north wall)
- New Addition Window-to-Wall Ratio = 20% (Assume 0% for south wall)
- Window shading coefficient
- Historic Window Shading Coefficient (Summer)
- East windows = 90% shade
- South Windows = 90% sun
- West Windows = 50% sun (will have deciduous trees shading the front..however they will be small at first)
- North Windows = no windows
- New Addition Window Shading Coefficient
- East windows = 90% shade
- South Windows = no windows
- West Windows = 50% sun (will have deciduous trees shading the front..however they will be small at first)
- North Windows = 50% shading need to determine the impact of the Victorian house on north windows)
- Historic Window Shading Coefficient (Summer)
- Has anyone ever come up with any sort of heating or cooling load estimate thus far? Did you have a Btu/h/sq. ft. goal in mind from all of your studies?
- No not yet that is what we're trying to do with V 2.0
- Assumptions for the walls and roof.I believe we were going to start with R=50 for walls and R=60 for roof, so that's what I based my first pass on.
- That's correct
- Average Wind Speed - I was also wondering from your wind rose experience if you had a "design" wind speed in mind for summer cooling through natural ventilation? I looked at the Sun, Wind & Light book, and it seemed like 4 or 5 mph would be a good number for July-August hot day to use.
- This is exactly right... 4 - 5 mph for the city center. It's easy to get numbers in the macro (Detroit) , but harder to get the numbers in the micro (our neighborhood).
- Dimensions of the floor of the buildings (area and wall exposures)
Earth-Air Tube Designs
- Earth-air tube design...page containing our design for the Green Garage
- Earth-Air tube Design -- details in Iowa ...they have a website dedicated to earth-air tubes.
- / heating tubes design
- Earth-based Passive Ventilation Systems found in wikipedia. It indicates that the bacteria actually decreases by putting it through the earth system.
- Earth tubes on DIY Solar ... Summary design guidelines ...very well done

- Earth temps at Various depths looks like 8 - 12ft would be helpful.
Solar heating
- Green Garage Solar Heating Design
- Solar Thermal Collectors
- Overall
- Goal = highest Heat Output / Total Cost
- where Heat Output (Q-out) = Temp Rise x Volume Flow Rate x Specific Heat of Water
- If you measure the flow rate of the water through the collector in gallons per minute, then the equation becomes: Qout = (Flow Rate gallons/min)*(8.2 lb/gallon)*(Toutlet - Tinlet)*(1.0 BTU/lb-F)
- Guidelines / Base Data
- Solar Modeling
- Goal = highest Heat Output / Total Cost
- Which type of collector is better?
- All Manufacturers
- Evacuated Tube
- Efficiency - better at higher temperature differentials...lower in a normal residential/commercial system (unless high temps are needed.)
- Cost - higher cost sf ... approximately $75/sf
- Durability - slightly worst...more complex design...ave 15 yr life...failure point is evacuated tube seals.
- Flat Panel
- Efficiency - better at lower to mid temp differentials...better overall performance once integrated into a system.
- Cost - lower cost per sf...approx $25/sf
- Durability - significantly better... ave 30 - 40 year life.
- Decision
- should be cost per BTU generated...why not just buy little more of a slightly lower efficient panel and get same total energy
- Manufacturers
- Sun Earth Imperial Flat Plate, single glazed, copper, selective absorber |0.714, -0.727 from Build it Solar
- Seido 1-16 Evacuated Tube, evacuated glass tube, copper selective absorber |0.529, -0.299 from Build it Solar
- How should the panels be positioned?
- Vertically
- Fixed position - per SRCC guide the panels should be 55 degrees (Latitude + 15 degrees) for winter heating driven systems.
- Horizontally
- What is solar "true" south?
- Tells you how to find solar south on our site
- Approx 14 degrees west of magnetic south(one estimate)
- What is solar "true" south?

- On a partly cloudy day? 600 BTU/sf/h (750 BTU/sf/h * 75% per Build it Solar)
- On a cloudy day? 375 BTU/sf/h (750 BTU/sf/h * 50% per Build it Solar)
- How many panels do we need?

- Efficiency
- Solar thermal (water) panels are up to 70% efficient ... 3 to 4 times that of PV panels
- The efficiency varies with delta T the greater the difference the lower the efficiency
- Thermal Storage / Mass
- Overall Design Guidelines
- Size
- Purposes are hot water (small) and heating (large)
- 10 gallons ( or approx 1 cu ft) for every 1 sf of solar panel if you want to get to near 95% of heating demand
- Hold four days of heat (Rushforth LLC uses 2+ days... and gets much better results than one day)
- Shape / Exchangers
- maybe break the tank it into 2 sections
- Put the coils for the heat pump in the water and it uses the heat from 90F down to 40F.
- Material
- concrete tanks are quite common
- Size

- Over existing concrete forum reply
- Gypcrete over existing concrete is an accepted and common practice. Any "cementious" material designed for the purpose will do. If you have a walk-out or suffer from high ground water than one inch of closed cell polystyrene would be in order if you live above the Mason/Dickson. Each manufacturer will tell you how deep to pour but an 1.5" is typical with a 1/2" cover over the tube.
