Como incorporar recursos de eficiência energética nas especificações de portas e janelas?

A great way to improve the energy savings and performance of single pane windows is to add a supplemental window system. Many windows can be retrofitted with an additional layer or layers of glass with low-E coatings and tinting in fiberglass frames. Installation is quick and does not provide interfere with daily operations. This can be done at a fraction of the cost compared to window replacements. We have installed numerous jobs saving clients substantial utility costs and improving the working conditions of the occupants.

Selecting high-performance materials is crucial for energy-efficient doors and windows. Opt for frames made of materials with low thermal conductivity, such as fiberglass or vinyl, which minimize heat transfer. Use insulated glazing, such as double or triple-pane glass filled with argon or krypton gas, to enhance thermal performance. Additionally, specify low-emissivity (Low-E) coatings to reduce heat gain in summer and heat loss in winter. Ensure that insulation materials, like polyurethane foam, are used in the frames to eliminate thermal bridging. By prioritizing these materials and insulation methods, you significantly improve energy efficiency, resulting in lower heating and cooling costs and enhanced comfort for occupants.

The orientation of windows and doors plays a significant role in energy efficiency. Position larger windows toward the south to maximize passive solar gain during winter, while minimizing openings on the north side to reduce heat loss. Incorporate overhangs or awnings to provide shading during the summer months, preventing excessive heat buildup indoors. Additionally, consider using exterior shading devices such as pergolas or louvered systems that allow for adjustable light control. Use landscaping strategically to enhance natural shading through trees and shrubs. By carefully planning the orientation and shading of doors and windows, you can optimize natural light while minimizing energy consumption for heating and cooling.

Effective ventilation and air sealing are essential for maintaining energy efficiency in doors and windows. Specify weatherstripping and caulking around openings to minimize air leaks that can lead to drafts and increased energy costs. Incorporate operable windows and doors to facilitate natural ventilation, enhancing indoor air quality while reducing reliance on mechanical systems. Additionally, consider including ERVs or HRVs to optimize air exchange without significant energy loss. Ensure that any ventilation systems installed are balanced to avoid negative pressure, which can increase energy consumption. By focusing on effective ventilation and airtightness, you create a comfortable living environment that conserves energy.

Incorporating energy-efficient doors and windows requires attention to certification and labeling. Specify products that have been certified by reputable organizations, such as ENERGY STAR or the National Fenestration Rating Council (NFRC). These labels indicate that the products meet specific performance criteria for energy efficiency. Encourage the use of third-party verified ratings that provide information on U-factor, Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT). This ensures that the selected products not only comply with energy codes but also contribute to long-term energy savings. By prioritizing certified products, you can confidently select materials that enhance the overall sustainability of the building.

To maximize energy efficiency, choose doors & windows designed for durability & low maintenance. Specify materials that withstand weathering & resist corrosion, such as fiberglass or treated wood, which ensures long-lasting performance & reduces the need for frequent replacements. Incorporate features that facilitate easy cleaning, such as tilt-in sashes or self-cleaning glass coatings. Regular maintenance schedules should be recommended to ensure seals and gaskets remain intact, maintaining energy performance. Also, educate building occupants about proper care & inspection practices. By prioritizing durable and low-maintenance solutions, you enhance the long-term energy efficiency of doors and windows, contributing to sustainability goals.
