Ahorro de energía y Agua en proyectos arquitectónicos


Energy Efficiency in Construction: Save Electricity, Water & Gas

In recent years, the demand for sustainable and energy-efficient construction projects has been increasing consistently. Architects and construction professionals need to be prepared to address these needs in the design and construction of buildings, which includes energy efficiency measures in the use of electricity, gas, and water.

In this article, we offer relevant information for architecture professionals to reduce heat loss, improve air quality, harness renewable energy, and reduce waste. To achieve this, several factors must be considered, such as building orientation, selection of construction materials, installation of efficient heating, ventilation, and air conditioning systems, incorporation of renewable energy technology, and implementation of water-efficient practices.

How can we find practical solutions to build for energy savings? Here are some relevant insights for optimizing these types of projects, intended for architecture project management, remodeling works, as well as any professionals interested in the industry.

Energy and Electrical Lighting Efficiency

Advantages of LED Bulbs

LED bulbs are an excellent option for efficient lighting, as they consume up to 80% less energy than traditional bulbs and have a longer lifespan. In addition to this, their use can result in significant reductions in the electricity bill.

Choosing the right LED bulbs to save on electricity One key aspect is selecting the appropriate color temperature for each area of the home. For example, in work areas like the kitchen and study, a cool white light of 5000K or higher may be recommended to enhance productivity and work focusing. On the other hand, for restful spaces like the bedroom and living room, a warmer light of 2700K to 3000K is advised to create a cozy and relaxing atmosphere.

It is important to consider that the choice of color temperature will also depend on the natural light received in each space. If a room receives ample natural light, a cooler light may be chosen to balance the color temperature in the room.

Designing to Reduce Heating and Air Conditioning Usage

To reduce energy consumption for heating and air conditioning, it is important to design an efficient thermal installation. For sustainable housing construction, it is recommended to use materials with high thermal mass, such as masonry, concrete, or brick, as they can absorb and release heat more effectively than other materials.

Placing and installing windows and doors in strategic locations is crucial to take advantage of natural ventilation, as well as the installation of controlled mechanical ventilation systems.

Windows require special attention as they can be weak points in regards to the building’s thermal efficiency. Windows should have high energy efficiency, with double or triple glazing and low-profile frames to reduce heat transfer and noise. Insulating materials such as PVC, treated wood, or aluminum with a thermal break can provide good light transmission and high-temperature insulation capacity. In addition, solar control films can be used to reduce the impact of solar heat inside the building.

Water Saving, Reuse, and recycling in Architecture Projects

Efficient Water Consumption Devices

Low-flow faucets and showers are designed to reduce the amount of water flowing through them. Some models come with temperature control technology to avoid water waste while waiting for it to heat up. For example, a low-flow showerhead can reduce water usage by 50% compared to a conventional showerhead.

In the case of dual-flush toilets, they have two buttons: one for full flushes and another for partial flushes, allowing the user to control the amount of water used in each flush. Compared to conventional toilets, dual-flush toilets can reduce water consumption by up to 67%.

Finally, waterless urinals are an efficient and low-water consumption option for public and commercial bathrooms. Instead of using water for flushing, these use a sealed trap that captures odors and prevents bacteria, resulting in a significant reduction in water usage.

Rainwater Collection Systems and Greywater Treatment

Rainwater collection and recycling systems allow for the collection, storage, treatment, and reuse of rainwater and greywater generated in the building. Rainwater collection systems are based on capturing rain that falls on the building’s roof and storing it in a tank for later use in non-potable tasks such as garden irrigation, surface cleaning, and toilet flushing.

On the other hand, greywater treatment systems involve the capture, treatment, and storage of wastewater generated from showers, sinks, and washing machines for later use in non-potable tasks, such as garden irrigation, surface cleaning, and toilet flushing. Greywater treatment systems can include various technologies, such as filters, membranes, and disinfectants, to ensure the quality of the treated water.

How beneficial are these sustainable reusable water systems? A good application of these rainwater collection and greywater treatment systems can supply up to 100% of the non-potable water needs of a building.

Gas Saving and Climate Control Improvements

Efficient Heating Systems

To achieve efficient heating and gas savings, it is recommended to install heating systems that allow for individual temperature control in each room. Zoned heating systems, using programmable thermostats, are an excellent option to improve the climate control of different spaces.

Additionally, high-efficiency boilers can be used to better utilize fuel energy and reduce gas consumption. These boilers often incorporate condensing technology, which harnesses the heat from the water vapor in the combustion gases to heat the water circulating in the heating system.

Another important aspect to consider is the efficiency of radiators. Energy-efficient radiators can be made of materials such as aluminum, steel, or copper, and can have a high thermal conductivity design to maximize heat transfer. Moreover, automatic air purging systems can be installed to prevent air trapped in the radiators from decreasing their efficiency.

Biomass and Geothermal Heating Technology

Biomass and geothermal heating technology are highly efficient and environmentally friendly alternatives for reducing gas consumption in buildings. Biomass heating utilizes renewable fuels such as wood pellets, wood chips, or fruit shell pellets to generate heat. Geothermal heating harnesses the heat stored in the ground to heat the water circulated through pipes and then distributed throughout the building.

Both systems can be very efficient in terms of gas savings, as biomass and geothermal energy are renewable and sustainable energy sources that do not generate harmful emissions. Additionally, they often have lower costs compared to traditional gas heating systems. However, the choice between these systems will depend on the type of architectural project and construction being developed, as well as the heating needs of the users.

To make the best choice, it is important to consider the geographical location of the building, its size, and the regional climate. Biomass heating may be a good option in rural areas where renewable fuels are readily available, while geothermal heating may be more effective in urban areas where biomass availability is lower. It is also important to consider the available budget and the installation and maintenance costs of both systems.

Planning a construction project that saves electricity, gas, and water not only benefits the environment but also the economy of homes and businesses. Here, went through some general guidelines for developing more ecological and green architecture. The implementation of renewable energy technology and low-consumption devices should always be tailored to the specific needs of each project.
