LEED Measures

Here is a list of some of the features of our home that qualify for LEED credits. This is not an exhaustive list, just some of the more interesting features:

  • Universal Design – every room in the home is usable by persons with limited mobility
  • Limit conventional turf – we will have no conventional turf at all, just gardens surrounding the house
  • Reduce irrigation demand – all our permanent plantings will have far less water demand than typical landscaping in this region
  • Water reuse – our rainwater harvesting system collects water from more than 50% of our roof, to be used for watering the gardens and flushing toilets
  • Indoor water use – all our toilets, lavatories and showers have very high efficiency fixtures that use much less water than conventional fixtures
  • Optimize energy performance – our home is designed to generate more energy than it consumes, using a combination of superinsulation, energy efficient appliances, active and passive solar heat collection, and solar electric generation
  • Construction waste reduction – our construction will generate about 1/10th as much waste per square foot as a typical home construction
  • Combustion venting – our wood stoves are EPA certified for low emissions, and have an outside combustion air supply to avoid drawing warm air from the house
  • Outdoor air ventilation – we use a heat recovery ventilator (HRV) to provide continuous ventilation, and to recover about 70% of the heat from the outgoing stale air
  • Local exhaust – our bathrooms are equipped with humidity sensors, which will increase the airflow through the HRV whenever excess humidity is present
  • Air filtering – the ventilation air intake is equipped with a high efficiency air filter (rated MERV 13) to reduce particulates in the incoming fresh air
  • Indoor contaminant control – we have a shoe removal and storage space near the front door, and a central vacuum system that exhausts to the outside

In addition, here are some of the environmentally preferable products in our home that earn LEED credits:

  • Floor – polished concrete generates far less emissions and traps far less dirt than carpet
  • Walls & ceilings – our drywall was made less than 200 miles away from 96% recycled material
  • Paints – All walls and ceilings use low-VOC paint
  • Countertops – we’re making our own countertops using recycled glass
  • Insulation – our cellulose wall insulation is about 85% recycled paper

Instructions

This tool will generate a PDF document containing a printable map ruler with user-selectable scales. It can include custom pace scales, which enable you to directly measure distances in your own paces on practically any map. We’ve had good results using a Brother P-Touch PC-Connectable Label Maker to print rulers onto 18mm Clear Label Tape, and you can also print on letter-size paper with a regular printer.

This should work in most browsers, but we recommend Google Chrome. If you are using FireFox and the ruler keeps opening in a separate application, there is an option to display the ruler directly in this page: in your browser’s Settings menu, under Applications look for Portable Document Format (PDF) and change the action to Open in FireFox.

With Chrome and most other browsers you can print a ruler directly from the preview window above (look for a printer icon) but if your browser doesn’t support that, you can click the Open PDF button to open the document in a new tab. When printing, look for a ‘Scale’ setting in your print dialog and make sure to set the scale to ‘Default’, ‘Actual Size’ or ‘100%’ (this can vary depending on which browser you are using). Don’t select ‘Fit to Page’ or similar, because it will mess up the scaling.

When using a label printer you will need to open the Printing Preferences dialog for your printer and set the Width to match the Print Format setting, and the Length to match the Ruler Length setting (see below). Here is an example, although your printer driver’s dialog may look different:

Print Format

The Print Format setting lets you specify a standard label tape width, or a letter-size page for printing on an ordinary printer. This deterimines the page size of the PDF document that is generated.

Upper and Lower Units

The units of each side can be specified, and if “Paces” are selected then a Pace Count can also be specified. For the Pace Count, enter the number of paces (two steps) it takes you to travel 100 meters. If you don’t know this number you can measure it by marking out a known length such as 50 or 100 meters and walking it while counting your paces. Repeat several times and average the result. You may want to print a scale with a larger pace count for rough terrain where it will take more paces to cover a given distance.

Ruler Length & Height

This is the physical size of the ruler that is printed. When printing labels it is recommended to set the Height equal to the full width of the label tape, although the printer may clip the index lines a little at the top and bottom edges. You can also reduce the height to make the ruler slightly narrower than the tape to avoid this clipping.

Map Scale

Enter the scale printed on the map, or measure the map scale if necessary. Some maps may show a scale such as 1:24,000 but may not actually be printed at exactly that scale, so it’s best to measure some features on the map to check the actual scale. To get the scale factor, just divide the real-world size of a known feature (such as the distance between two road intersections) by the physical distance measured on the map in the same units such as meters. The drop-down list at the left lets you enter common map scales easily, but you can also type an arbitrary scale into the box to the right.

Printer Scale

This lets you fine-tune the scaling to match a particular printer, because printers don’t always print things at exactly the specified size. Adjusting this is usually not necessary because measuring distances by counting paces is an approximate technique that’s affected by things such as terrain, so if a ruler is off by 1% it probably won’t matter. But if you want your ruler to be as accurate as possible then you need to experimentally determine your printer’s scale factor.

A simple way to do this is to set the map scale to 1:10,000 and the printer scale to 1.000, and print a ruler that shows a range up to 1.0km. Then measure the physical length of 1.0km on the printed scale, which ideally should be 100mm. If it is not, divide the printed length by 100mm and enter this number into the Printer Scale box. For example if it prints 98.3mm wide then enter 0.983. Try printing again and the resulting print should be extremely close. You can tweak this value experimentally, keeping in mind that making the Printer Scale larger will make the printed ruler shorter.

Mirror Image

Checking this box produces a mirror image of the ruler. This can be useful to eliminate parallax by attaching a clear label to the underside of a plastic sheet as described below.

Printing Problems?

If printing directly from your browser doesn’t work right, it may work better to save the PDF document to your computer and then open it in Adobe Acrobat Reader in order to print it. You can use the ‘Download’ button in the PDF preview panel above if your browser provides one, or click the Open PDF button to open it in a new tab and then use your browser’s Save-As menu (Ctrl-S in Chrome) to save the file. Here’s an example (thanks to Bill who figured it out!) of the Brother PT-D600 properties and Adobe print dialog:

Practical Guidelines

Single-scale rulers can be printed as narrow as 6mm (1/4″), which works well for adhering directly to a compass like this:

Two-scale rulers work better when printed on 12mm (1/2″) or 18mm (3/4″) clear label tape and affixed to a sheet of clear plastic:

As shown in these images, you can measure paces quite accurately from orienteering maps if you align the index marks with the edges of the circles instead of the center.

The following are a few different methods to print and assemble this kind of ruler. For any of these methods, an ordinary paper punch works well to punch a hole on the right hand side (opposite the map scale) so you can keep your rulers together on a lanyard.

Easy

Use a Brother P-Touch PC-Connectable Label Maker to print a ruler onto 18mm (3/4″) Clear Label Tape, and stick the label onto a sheet of rigid clear plastic. The Mirror Image option is recommended so you can place the label on the underside of the plastic sheet, especially if the plastic is somewhat thick, because it puts the printing right on the map to reduce parallax.

A good source of clear plastic material for rulers is the clamshell packaging in which many products are frustratingly packaged, as it often has flat areas large enough to cut out ruler material. Another good source is the thin clear lids that come on things like boxes of chocolate. If you can’t find any recyclable material that’s suitable, office supply stores carry all sorts of items made of clear plastic that can be cut up and used.

Cheaper

If you don’t have a label printer, you can print a ruler onto plain paper or transparency film and then laminate it using a thermal laminator.

Cheapest

Print the ruler onto ordinary paper or heavy card stock, optionally apply clear packing tape on both sides to make it more durable, and cut it out. You won’t be able to see through it but it still works if you cut right up to the tick marks.
