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.
In most structures, windows account for 10 to 25 percent of the total heating bill by allowing hot or cold are to enter. During the summer months, HVAC systems work harder to cool hot air from sun exposed windows. Best to replace inefficient windows with double-pane or low-emissivity coated models, which can reduce energy loss by anywhere from 30 to 50 percent.
- Clean Refrigerator Coils – Coils can collect dust, making them less efficient for cooling. Be sure to clean coils two times per year to eliminate buildup and reduce energy use by up to 6%.
- Clean Ventilation – Air conditioning vents and dirty air filters should be cleaned and/or replaced regularly. Changing filters can reduce HVAC energy use and electricity costs from 5 to 15%.
- Inspect Vent Hoods – Check vent hoods for need of cleaning or filter replacements.
Energy Star certified ventilation fans can use 60% less energy than standard models.
Fix leaks. The most common fixture that leaks is the toilet flapper. Checking for leaks should be part of your overall maintenance plan and should be done on a regular basis. Perform a water audit. Take a look at your water meter when no one is likely to be using water. If the meter is moving, you have a leak.
Install water-saving devices. Can you transform your single flush toilets to dual flush with a kit? How about installing a Smart Faucet in every bathroom? The EPA has rolled a complete line of water saving fixtures under its WaterSense label, however, but these are merely minimums. Individuals should go beyond the minimum by installing 1.5 gallons per minute (gpm) shower heads when the WaterSense minimum allows shower heads with flow rates of 2.5gpm. Rebates may also be available from your local utility to promote the installation of new high efficiency toilets that utilize 1.28 gallons per flush or better.
Upgrade to water saving appliances. Old dishwashers and top-loading washing machines are incredible inefficient, utilizing as much as 25 gallons per load of dishes and 35 gallons of water per load of laundry. New high-efficiency models utilize a fraction of the water. Dishwashers in the two gallon range are very effective and front-loading washing machines use about a third of the water of what top-loaders use and rebates may be available. The less water an appliance uses, the less electricity and natural gas that will be needed to heat that water.
Rethink landscaping. Plant what’s appropriate for your region and you will reduce water consumption, increase habitat for native species and raise the value of your property. Re-landscaping is a big expense, but you are paying to water and maintain plants every year, year and year out, when you could be pocketing the money you currently budget for water.
On 8:30pm, Saturday 29th March, the WWF are encouraging everyone to switch their lights off for 1 hour to help recognize the increasing problem of climate change. It is widely accepted that climate change is causing the ice caps to melt and seas to warm, threatening ecosystems and coastal areas around the world. This is also causing related effects in other places as rising temperatures are causing increased droughts , threatening the most vulnerable animals and people worldwide.For just 1 hour, 8:30pm, Saturday, March 29th, many landmarks and cities throughout the world are showing their support for Earth Hour and recognizing the danger of climate change by switching the lights off during this time. To find out how you can participate, go to http://www.earthhour.org/TakeAction.aspx.
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.
