Sustainable Architecture in Criciúma: Comfort that Also Adds Value to the House

Updated on 07/06/2026 by EZA Engenharia

Sustainable architecture is no longer that differentiator only a few clients asked for now and then. Today, those building a high-end house in Criciúma and the surrounding region come to the first conversation already asking about solar power, water reuse and thermal comfort. EZA Engenharia has been building for more than 35 years and has followed this change closely: what was once a whim has become a requirement, and rightly so, because the return shows up in the electricity bill, in day-to-day comfort and in the property's value down the road.

What sustainable architecture is in practice

Sustainable architecture is the set of design and construction decisions that reduce the consumption of natural resources and the environmental impact of a house, without giving up comfort or aesthetics. In practice, it starts before the foundation: in reading the lot, in solar orientation, in the winds that prevail here in the Criciúma region.

It's not a fixed package of items you tick off a list. It's a way of thinking about the entire project, from start to finish. The positioning of a window, the type of roof tile chosen, all of it weighs on the energy performance and comfort of the house for the coming decades.

• Solar orientation of the design to take advantage of natural light and heat
• Materials with better thermal and acoustic performance
• Rainwater harvesting and reuse systems
• Photovoltaic solar power generation
• Cross ventilation and strategic shading

Solar energy: the savings appear over time

Installing photovoltaic panels is one of the most frequent requests from those building a high-end house in Criciúma and the surrounding region, and for good reason. The return shows up in the energy bill, which plummets, especially in houses with climate control, a pool and other equipment that draw a heavy load.

The right sizing of the system depends on the family's consumption, the available roof area and the orientation of the house. That is why this planning needs to be part of the project from the initial phase, together with the electrical engineering. Leaving it for later usually leads to rework and an underused system.

Water reuse and passive comfort

Reusing rainwater for non-potable purposes, such as watering the garden, washing outdoor areas and supplying the toilet flush, reduces consumption from the public network and gives the house more autonomy. In Içara, Forquilhinha and Balneário Rincão, where many homes have large gardens and ample leisure areas, this system makes a visible difference in daily life.

Passive comfort, in turn, works in favor of the climate in the south of the country: cross ventilation, brise-soleils, pergolas and well-positioned vegetation reduce the reliance on air conditioning. The result is a home that is cooler in summer, cozier in winter, and with a much lower spend on climate control.

• Cisterns for rainwater harvesting
• Faucets and flush systems with flow control
• Brise-soleil and pergolas for shading the facades
• Strategic vegetation to reduce direct sun exposure

Property appreciation: an effect that shows over time

Houses designed with sustainable architecture criteria tend to be worth more on the market, because they cost less to maintain and operate, and that weighs on the mind of whoever will buy later. Real-estate appraisals already consider energy efficiency and sustainability systems as points in the property's favor.

But the gain is not only on resale. It is in the quality of life of those who live there every day: less corrective maintenance, less spending on energy and water, more thermal and acoustic comfort inside the home.

The construction company's role in this process

It is worth understanding the difference between a real-estate developer and a construction company, because this confuses a lot of people. The real-estate developer launches and sells developments. The construction company is the one responsible for the engineering and the physical execution of the project, from the structural design to the final finishing. EZA Engenharia operates as a construction company, with an in-house engineering team overseeing every stage of the residence.

It is this hands-on involvement that allows sustainable architecture to be integrated in a technical and safe way, without compromising schedule, budget or execution quality. In projects such as Residence V.S, in Criciúma, and Residence A.F, in Balneário Rincão, these criteria were part of the conversation from the very first sketch of the design and continued all the way to the handover of the keys.

EZA Engenharia has been building high-end homes since 1991, and it is this hands-on construction experience that underpins every sustainable architecture criterion applied in the team's projects: no decisions made only on paper, everything designed to truly work once the family moves in.
