Urban Heat Islands

Hot town summer in the city

Hot town summer in the city

Edited by Allan Britnell

For the last 100 years, scientists have been exploring the reason why temperatures are so much warmer in the city compared to the rural areas surrounding them. This phenomenon, called an urban heat island, is a direct result of our activities.

Unfortunately, with global warming, this increased heat continues to go up in areas with lots of stone and concrete like parking lots and even in our own backyards. Even though more cities are investing in green spaces and promoting green roof technology, several online sources state that more than 70 percent of all of the surfaces that we are currently installing in our landscaped spaces are concrete, pavement, stone, or pavers. We are turning our own backyards into mini urban heat islands! Now if you have a client who wants a patio or if you specialize in stone masonry and installation, then there is good news. There are simple ways to reduce the heat in the backyard and still have a beautiful space that will not only last for years it will help increase the home’s value.

Help your clients choose lighter stone colours. Dark stones using black or dark grey pigments have been very popular for the last decade. Like wearing black clothes on a sunny day, dark stone choices heat up way more than the lighter options. White paving stones have become very popular for designers because of the modern aesthetic. Unfortunately, while going with a white paver might be better to displace heat, the idea of the sun bouncing off of the surface already makes my eyes hurt just thinking about it. Instead, I try and move my clients towards lighter colours that have flecks or speckles of darker material in them.

Throwing shade: Cantilevered umbrellas keep the sun off of guests, while rugs help prevent stonework from absorbing too much heat.

Incorporate shade into the design

By increasing the amount of permanent shade on the patio, you reduce the amount of sunlight and heat that the stones actually absorb. I’m a big fan of a pergola with large fabric panels that can be installed every spring and removed before the snow. This is such an important add-on to any project. Make sure to ask your clients if they have planned on adding shade. If a pergola is not for them, suggest using a large umbrella. I’ve been impressed with a lot of the new technology in umbrellas lately. Solar-powered models that are cantilevered with a good heavy base not only allows you to create shady all day long, they also charge in the sun, creating free light wherever you need it at night!

Simply adding an outdoor rug is also an effective way of displacing the heat. While stone may absorb and hold the warmth of the sun, the synthetic fibres of outdoor rugs don’t. Even the darkest rugs hold significantly less heat than a dark patio stone. They also act as a barrier between the sun and your patio, preventing it from heating up in the first place.

This summer is going to be a hot one across the country. Lets educate our clients so that we all work towards managing the urban heat islands that we are creating in our backyard.

Top 5 Spring Trends

It’s a time to switch things up, refresh and renew your home and backyard.

by Jo Alcorn

I love spring! It’s a time to switch things up, refresh and renew your home and, more importantly, your backyard.

I’ll be at the Backyard Living Expo — coming on April 6 to 8, 2018 at the International Centre —  for an on-stage presentation at 1:15 p.m. and would love for you to join me to talk about all things backyard decor and design. As a sneak preview, here are my top 5 tips and trends for this season.

 

High Performance Outdoor Sound

I love music and I play it all day long and there’s no exception when I go outside to relax and enjoy the warmer weather. I love the high performance outdoor sound that Paradigm has to offer. Long gone are the days of the boom box or the huge speaker systems. This company offers discrete luxury speakers that can be wall or deck mounted and faux rocks that can mix right into you garden, There is even a garden oasis systems with an underground subwoofer for large areas.

 

Shading Style

While I love the outdoors, shade is of the utmost importance. This year I am obsessed with pergolas. They have retractable systems that allow the light to shine in when you want a few rays, but you can also crank the roof closed when you need some shade. The great thing about these systems is that they can be built to spec for odd shapes, attached to an existing structure or they also have great stand-alone units.

 

Grilling Galore

There is nothing Canadians love more than firing up the grill and when your grill can match your decor it’s even better! I love the new Weber Spirit ll series that comes in four bold colours so you can add the perfect barbecue to match your decor. My choice this year would be the gorgeous ivory colour to add to my small space patio.

Burn Baby Burn

Adding a fire element to an outdoor space helps to elongate the season, creates an atmosphere of warmth (literally warm up next to the fire) and just adds a touch of sophistication. You can choose a stand-alone unit that can be purchased at most big box stores or, if you are creating your space from scratch, it’s great to incorporate a built-in unit that fits right into your design.

 

The Final Touches

I love adding accessories to an outdoor space that really tie it all together. Homesense has amazing seasonal accessories that bring your space to life at affordable prices. I love to add trays, lanterns and faux plants (yes, even in an outdoor space) to my backyard designs. Pillows are also a great way to add colour and comfort to your space. I have an entire line of outdoor pillows that are fully washable and are available on my site in a variety or colours and patterns.

Use these ideas to create your very own backyard oasis. Discover the secrets behind the perfect barbecue and learn how to make the most of your backyard, no matter the size or the budget, from industry and celebrity experts at the Backyard Living Expo, which runs from April 6, 7 and 8, 2018 at the International Centre, 6900 Airport Road, Mississauga.
