Hot roofs absorb heat, causing air conditioner systems to work harder to cool during the warmer months of the year.
A cool roof uses material that is designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles. Cool Roofs can lower the temperature of your roof by up to 50 degrees, which will reduce cooling costs.
The Hovenring is an incredible suspended roundabout designed by IPV Delft to allow cyclists to safely navigate congested traffic by traveling above it. The Hovenring is located between Eindhoven and Veldhoven in the Netherlands. The circular steel bridge not only offers an alternative route for cyclists, but is also aesthetically pleasing landmark for locals and tourists.
The structure adds is an intriguing element to the landscape, with a pylon that soars approximately 230 feet high with 24 steel cables attached to it, holding the circular pathway up like a hovering saucer. The Hovenring provides spectacular viewing in daylight and at night, when the structure is illuminated. The Hovenring bicycle path offers an innovative approach to future road designs focused on efficiency and safety.
Caulking seems like a relatively easy thing to do, and in most cases it is. There are simple tips and tricks that can make a big difference between a easy, seamless, hassle-free caulking job and one that’s messy and full of frustration. Before you start your next caulking job, here are a few things to keep in mind.
- Purchase a good-quality pro-style caulking gun ($10). Skip the cheap low-end guns that utilize a ratcheting plunger. Ratcheting guns don’t operate smoothly, making it hard to apply a clean, uniform bead.
- Use blue painter’s tape to protect your windows and the other side of the joint you are trying to fill. Leave a gap between the tape about 3/8ths of an inch wide.
- Find a utility knife as when you cut off the top of the caulk tube, you do not want an uneven or straight cut. Make the cut at a 45 degree angle.
- When you apply the caulk you will hold the caulk gun at approximately 45 degree angle.
- Bend a piece of cardboard and practice on the seam before you attack your first seam. You could start in a less visible area where any mistakes will be less noticeable.
- After you apply the caulk, use a plastic spoon to smooth the seam so that it is more or less flush.
- Keep the tip of your caulking tube clean and free of dried caulk.
- Make sure you pull the tape off before the caulk dries to leave clean seam.
Proper caulking and sealing will lead to an increase in energy efficiency of a home’s heating and cooling systems. Caulking can also substantially extend the life of windows and doors.
Save money and energy this winter with these garage winterization tips:
- Install a weather seal between the bottom of the garage door and the garage floor.
- If time to replace your garage door, replace with an insulated door.
- Check the door leading from your garage to the house for leaks and replace seals, if necessary.
- Properly insulate rooms that share walls with the garage.
- Insulate your hot water heater.
- Install energy efficient lighting.
- Insulate all exposed pipes.
Test For Air Leaks and Drafts to Reduce Energy Loss
Properly sealing cracks and openings in you home can significantly reduce heating and cooling costs throughout the year. You may already know where some air leakage occurs in your home, such as an under-the-door draft, but you’ll need to find the less obvious gaps to properly seal your home.
Here are several tests that can be used to check for air leaks:
- Window Seal Check – Shut the window on a piece of paper. If paper can be pulled without tearing paper, than window should be resealed.
- Visual Gap Check – After daylight hours, shine a light through closed window and door seam and have a partner confirm if light is visible on other side.
- Hot/Cold Air Check – Use your hands to feel around door and window seal checking for cold or hot air coming in through a leak.
Common areas to check for leaks are between brick and wood siding, between foundation and walls, and between the chimney and siding. In addition, you should inspect around these areas for leaks and drafts:
- Door and window frames
- Mail chutes
- Electrical and gas service entrances
- Cable TV and phone lines
- Outdoor water faucets
- Where dryer vents pass through walls
- Bricks, siding, stucco, and foundation
- Air conditioners
- Vents and fans
Home Pressurization Test
If you are having difficulty locating leaks and drafts, you may want to conduct a basic building pressurization test:
- First, close all exterior doors, windows and fireplace flues.
- Turn off all combustion appliances such as gas burning furnaces and water heaters.
- Then turn on all exhaust fans (generally located in the kitchen and bathrooms) or use a large window fan to suck the air out of the rooms.
This test increases infiltration through cracks and leaks, making them easier to detect. You can use incense sticks or your damp hand to locate these leaks. If you use incense sticks, moving air will cause the smoke to drift, and if you use your damp hand, any drafts will feel cool to your hand.
Your central heating, venting and air conditioning (HVAC) unit may be sending conditioned air to unwanted areas, such as attic and crawl spaces. Check your ductwork for leaks or have it inspected by an HVAC professional. Sealing leaks will keep you from wasting home energy and save you money.
