This article is part of our new “Material Focus” series, which asks architects to elaborate on the thought process behind their material choices and sheds light on the steps required to get buildings actually built.

The Enseada House project was developed by the Porto Alegre office of National Architecture in 2015 and is 317 square meters with an interesting interplay between volume and materials. We talked with the architect Paula Otto, one of the designers to learn more about the material choices used in this project and the role that these choices played in the design concept.

What are the main materials you used for this project?

PO: Concrete, wood, stone (marble) and glass. In addition to those, we used some vegetation incorporated into the facade.

What were your main sources of inspiration and influence when choosing the materials used in the project?

PO: This basic combination of concrete and wood is very classic since they contrast and complement one another cooler and warmer. The use of vegetation on the facade is something that fits the project well and is increasingly used in contemporary architecture, references that we respect and influence us in a positive way.

Describe how decisions on materials influenced the project’s design.

PO: The project arises as a result of the composition of pure volumes. The goal was that the three distinct volumes of the house read very clearly. On the lower level, we would have the timber volume and the vegetation volume, upstairs we have the concrete volume. To make it so that the frames don’t break the uniformity of the concrete volume on the second floor, we used marble louvers (in very similar tone to the concrete) incorporated into the volume.

What were the advantages that this material offered to the construction of the project?

PO: Concrete was used as a structural element, without any other kind of coating. In this case, great care was taken with the numbering of the formwork, since any marks would be visible. Wood (in the shape of vertical louvers) was used as the light and privacy control element with foldable openings. Developed by the office together with the supplier, the louvers have a design that, when closed, make up the volume of the ground floor. The advantage of using wood for this comes from its format, flexibility, and handling.

Did the choice of materials create any challenges for the project?

PO: I think it made it more challenging to get specific things from the suppliers. In the case of wood, with respect to designing the louvers, and in the case of aluminum frames, finding a supplier who could develop a frame with more than 3 tracks. But the biggest challenge was developing the mounting details for the marble louvers on the facade. All in all, we talked to seven different providers before finding one that did the details correctly and was in line with the project.

Did you ever consider other possible materials for the project? If so, how would that have changed the project?

PO: No. This particular project started out being very similar to what was implemented, the materials were well defined from the very first sketches.

How did you research suitable suppliers and builders for the materials used in the project?

PO: We end up looking for suppliers that meet our needs in relation to specific materials and especially the detail necessary for the project. We try to create a network of relationships that will end up being used in future projects. We look for suppliers ready to move away from the familiar and work on details with the office. We believe that new proposals are crucial for the supplier’s growth as well. Being open to new challenges are qualities that we value greatly in our partners. The means of finding these suppliers are through internet searches and specialized fairs, but particularly on visits to other sites (where we can see live materials) and by referrals.

Can We Guess Your Personality Based On Your Taste In Music?

Our tastes in music can say a lot about our personality. It’s obvious that an introverted will never have the same tastes as an extroverted. The likeability of music is very subjective, because it’s based in our own preferences that go into our judgements.

Have you noticed that a certain moments in your life, the preferences have slightly changed? That’s because your moods were different then. However, your tastes are not likely to change dramatically.

musicSo, take now this quick, fun quiz to find out what your taste in music says about your personality!

Why Owen Smith is wrong to talk about a Labour split

The Labour leadership challenger is being misguided – a divorce would only damage all sides

Is the Labour party in imminent danger of splitting? In a Guardian interview, the leadership challenger, Owen Smith, says it may if Jeremy Corbyn remains in charge.

On Radio 4’s Today programme, the shadow chancellor, John McDonnell, dismissed the warning as misguided. “There is no way I am ever, ever going to allow this party to split.”

What Would a Home Economist, an Environmentalist, an Allergist, and Your Mother Say About Your Home Windows?

//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js

We’re always being told that home replacement windows are a wise decision especially when retiring any window older than 10 years for a new Energy Star-rated window. Anyone would expect a window salesman to tell us that, but we didn’t invite the window pitchman into the conversation.

Ok, we know mom would say, “Did you run out of glass cleaner?” and then go to the kitchen to make refreshments whether anyone wanted a snack or not.

If the windows were the topic of conversation with the other three guests, what would they say?

The home economist has taken a moment to compliment you on not having multiple copies of the same electronic devices (not 2, just 1 flat screen display; not 2, just 1 play station; etc.). But when it comes to the 14-year-old windows, she begins interrogating you about your energy bills and the single glazed aluminum double hung foggy panes she’s having to try to look through to see the front yard.

She gives her best over the glasses lecture about the certainty that home utility bills can significantly impact the household budget for good or for bad. She wastes no time lining out the costs of the electricity bill in the average American home:

• 44% HVAC systems (heating and cooling)
• 33% Lighting and other appliances
• 14% Water heating
• 9% Refrigeration (refrigerator and freezer)

“Replacing a set of 5 single glazed windows with Energy Star-rated insulated window replacements will reduce a 2,000 square foot home utility bill by 18%,“ she smugly states as she reaches for the lemon zinger cookies your mother set out for the curious guests. (Of course, you know that the average American 2,000 square foot home expends a minimum between $1,400 and $2,000 for utilities annually).

That prompts the environmentalist to chime. “You know that each American home produces more harm for the environment than their gas guzzling vehicles do, right?”

//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js

The HVAC systems have to work harder when home windows are like slotted spoons letting outside air through crevices and cracks, instead of having sealed casement frames to keep the conditioned air inside. Overworked HVAC systems leak refrigerants that damage the environment and contribute to global warming.

This is not even mentioning the increased load to produce the energy, send it through overworked channels and deliver it through weakened grids to every household in your neighborhood and throughout the United States. Does rolling brownouts or direct blackouts mean anything to anyone?

He doesn’t stop there. The older windows can be recycled for their glass and framing materials while the newer windows are constructed from cast off materials already manufactured and redesigned. The additional foam insulation and batted insulation along with putty, caulk and paint all can come from recycled materials and landfills can be used less and less.

As the environmentalists reaches for his third cookie (but who’s counting), the Allergist coughs and wheezes to accentuate her remarks. “There is no barrier to the allergens, pollutants, and insects that gain entry through these loose and cracked window frames. If I had an aromatic incense stick, I could show you the smoke trail conning behind as the wind comes seeping by the panes” (if you’re not from Oklahoma you may not know their state song lyrics, but the lady was trying to be funny).

Over 50 million Americans suffer from airborne allergens and the most common indoor/outdoor triggers are cat, dog and rodent dander; cockroach and dust mite allergens; mold spores; grass, tree, and weed pollen according to the Asthma and Allergy Foundation (AAF).

The University of Iowa Department of Environmental Health study found that traditional room side blinds collected indoor airborne allergens 200 times more than between-the-glass window shades.

The air quality is further hampered due to the moisture collecting from condensation differences between the moist air on the inside and the dryer air on the outside. Some folks even over-compensate with humidifiers in the home to offset the warmer dryer air of the summer months and to their own peril introduce more damage to their health.

With a sharp cough, she’s done.

What a home visit!

Here’s what we know will be of importance to all your guests:

Replacement windows will pay for themselves within five years of installation. Any homeowner can calculate within a few dollars the actual savings for their specific home even before they purchase replacement windows.

Interestingly, there are free programs like RESFEN that allow users to identify and pick the most energy-efficient and cost-effective window.

A homeowner or builder can describe his climate, the specific square footage of the entire home or just a specific room, the heating and air conditioning system being used, and utility usage. It even gets so precise as to include the window dimension, the orientation as to which point on the compass the window faces, and any environmental factors such as shade trees or vegetation affecting the window site.

Once the homeowner adds in the specifics of the window replacement, such as U-factor or light transfer ratio (easily provided by the manufacturer), an accurate annual heating and cooling cost is calculated allowing for seasonal spikes unique to the homeowner’s geo-tract neighborhood.

Energy Star replacement windows may provide you with a state or federal tax credit and you can know with just a quick little call to 1-800-TAX-FORM or your state tax people. In many cases the credit is 10% of the purchase price and in some cases includes the labor costs.

The value of the home is increased by 5 to 7% on average with the windows upgraded to Energy Star standards. When up for sale, new buyers look for every angle of perpetual savings they can find.

Imagine being able to provide a print out of low utility costs for a house your size! Even if you don’t move, the enjoyment of savings is still yours.

So, once the guests leave and mom has taken to using the glass cleaner on those windows of yours, it’s time to contact a home window replacement professional in your area to provide you an official quote for home window replacement installation just for you.

Who invited all those people over, anyway? Mom, if you’re still here, where are those lemon zingers?
