Calculating the correct CFM (cubic foot per minute) for your bathroom fan is important. We need the capacity of changing or replacing all of the air in our bathrooms 8 times each hour. This will remove the moisture that can lead to mold and mildew.  Interior design by Jil Sonia Interiors, Abbotsford, BC Large bathtubs and showers can give off a lot of steam - which can be relaxing and enjoyable - but - we don't want that steam to stick around. So how do we get rid of it? A correctly sized fan will help keep our home comfortable and remove the moisture quickly and effortlessly.  Ancona Brezza 90 cfm bathroom fan from Costco.ca Here's how to calculate the correct numbers, so your fan draws out the extra moisture, but isn't too powerful (making it quite noisy). First, we need to calculate the volume of the bathroom. Take the length of the room and multiply it by the width of the room. Take that # and multiply it by the height of the room. ie. 7' width x 10' length = 70. 70 x the height of the room (9' or however high your ceiling is) = 630. Now take that # and divide it by 7.5. Why 7.5? Well remember how I mentioned our air needs to be exchanged 8 times per hour? Well that works out to being changed every 7.5 minutes. So 630 divided by 7.5 = 84 I always round up, so that means a fan rated 100 cfm, will be perfect for our bathroom. Hope this helps keep your bathroom well ventilated so you can enjoy those luxurious hot showers!

There are an amazing amount of beautiful range hoods available now. Glass, steel and custom wood are all options. But, you need to know the SIZE of range hood you need, not the dimensions, but the amount of CFM (cubic feet per minute) needed for your hood. First you need to select your stove, or cook top. Then you need 100 CFM for every 12" of stove width. For example a 30" stove (2.5') x 100 CFM= Approx. 250 CFM needed, as a minimum. But we can't just stop there...  Kitchen steel hood, interior design by Jil Sonia Interior Designs, Abbotsford, BC We need to keep the room size in mind. Larger rooms need more CFM to clear the cooking odours away. A range hood should exchange the air in the kitchen 15 x per hour. If your kitchen is 12' x 15' and 10' high, that equals 1,800 cubic feet. To find the size of fan needed, multiply the cubic feet x the # of air exchanges (15) then divide by 60 (minutes in an hour). In our example that would be: 1,800 x 15 = 27,000 divided by 60 = 450. You need 450 CFM minimum for this size of kitchen.  Kitchen hoods. ca  Are we finished? Not yet. Gas ranges deliver a lot more heat than electric ranges. So we need to take this into consideration. Most gas burners put out approx. 10,000 BTUs per burner. Multiply that by the number of burners, 5 shown here = 50,000 BTU Then divide by 100 to find the minimum CFMs needed. In this case 500 CFM. Now we aren't quite finished. What about the size of the duct work, number of turns, etc.? Most HVAC suppliers recommend smooth 8" metal pipe. Add 1 CFM per foot of pipe and add 25 CFM for each bend and 40 CFM for the roof cap. Let's estimate this example as being 100 CFM needed. Now, we ARE finished. Take the rating for the stove width (250 CFM in our example), room size (450 CFM minimum), burner type (500 CFM minimum). The highest number is 500, then add your duct work CFM calculations (100) and you would need a total of 600 CFM for this range size, kitchen size, range burner and ductwork. I hope this helps. Be sure to discuss this with your contractor and appliance providers. Check out our 15 steps to design your dream home blog posts!

Floor plans and elevations. 3. Function Then steps 4-6 of designing your dream home: 4. Budget 5. Mood and Style 6. Overall design And steps 7-9 of designing your dream home: 7. Bathroom and Kitchen design 8. Furniture Plan 9. Lighting plan Now... we move on to steps 10, 11 and 12 ! 10. Window coverings: When designing your dream home, be aware of oddly shaped windows. For some reason architects love to add them in! Notice the angle at the top of the window below, it dips down in the centre. 
These windows are very difficult to cover. If you like horizontal blinds these can usually be used in some of the more difficult, or odd shaped windows, however not everyone likes horizontal blinds. Many clients prefer window coverings that can be slid to the sides so that all of the glass is showing. Transom windows (especially if they are arched), although beautiful, are especially difficult to cover. (Please do not cover windows with furniture as in this photo below!) 
Determine what kind of light coverage do you need. Do you sleep in - then curse the sunlight in the morning; or do you embrace it? You may need room darkening, or light filtering blinds. Do you have a window needing privacy? A window with lots of glare? Many solutions are available.

Discuss your drapery needs with an interior designer or window coverings specialist. Note these can be a little pricey, 30% of your room's budget usually goes towards window coverings.
11. Fabric: OK, so we are really getting to the styling part here. We know the mood we want to achieve. But where do we go from here? One idea is to start with a ‘signature fabric’, this is a fabric that sets a style or creates your desired mood. Determine the placement of your signature fabric. This can be an expensive fabric - perhaps use it just for the front of a small pillow. Confirm your signature fabric suits the ambiance you desire. Use this fabric to set the colour tone of your room. 
Now select complementary fabrics, but allow in general, no more than three different patterns in one room! Determine placement of all fabrics i.e: - patterned drapery fabrics for the windows - like the example above - perhaps a cream and raspberry stripe for an ottoman, - teal polka dots for the chair backs. Finally select trim to customize draperies or throw cushions. Then use your signature fabric to pick colours for the rest of the room.
12. Wall colour:
Now you can finally pick a wall colour! Can you believe we had to wait until step 12 for this? Wall color is not usually picked until near the end of the design, as there are so many different colours of paint to choose from. Kimberley Seldon says " picking a wall colour first is like buying a lipstick, then look all over trying to find a dress to match." 
Remember to keep the room’s atmosphere in mind. What is your light level? Resist the urge to paint a dark room in a light colour. Donald Kaufman says "Light wall colours never come to life in a dark room..." If the room is sunny, play that up - don't use a dark colour for the walls. Look at your signature fabric for wall color ideas. I can go on and on about colour but really colour expert Maria Killam says it best when she says "Painting a dark room in pale colours simply accentuates the shadows in a space." Other questions to ask when selecting a colour 'theme' : Are you drawn to warm, neutral or cool colours? Do you prefer many colors or a monochromatic look? Personally I throw out the colour theory I was taught in design school. I don't understand how someone can look at a room and say "do I want a complementary colour scheme? What about the split - complementary colour scheme or maybe an analogous colour scheme?" 
Maybe, just maybe those theories come into play when looking at how to spice up a room with accessories or accents, but in general the main points to remember are: ensure the colour flows from room to room, keep either a clean, (or conversely), a muted or a dirty colour scheme throughout, and remember to consider the undertones - more about that in a later post.
