Boston’s Masonry Contractors Rise to Meet New Energy Efficiency Challenges with Innovative Thermal Mass Solutions

As Boston implements some of the nation’s most stringent energy efficiency requirements, masonry contractors are stepping up to help property owners meet these ambitious green building mandates. The city’s adoption of the Specialized Code, which affects all new building construction within the City (after January 1, 2024) and existing buildings that propose significant renovations, requiring that all such buildings be Net-Zero Buildings upon completion of construction, has created both challenges and opportunities for the masonry industry.

Understanding Boston’s New Energy Efficiency Landscape

Boston’s energy efficiency requirements stem from Massachusetts’s mandate to update its building code every three years to be consistent with the most recent version of the International Energy Conservation Code (IECC), ensuring that new buildings are designed and constructed with energy efficiency in mind. The city has gone further by implementing a specialized net-zero opt-in code that applies to new construction and is designed to help ensure that new construction is consistent with a net-zero economy by 2050.

These regulations require buildings to meet one of three compliance pathways, with all multifamily housing over 12,000 sq. ft. required to achieve Passive House certification in addition to meeting one of the above pathways beginning in January 2024. For masonry contractors, this means adapting their traditional practices to support these high-performance building standards.

The Thermal Mass Advantage in Green Building

Masonry contractors have discovered that their traditional materials offer significant advantages in meeting these new energy requirements. Thermal mass tends to decrease both heating and cooling loads in a given building, with buildings constructed with masonry requiring 18% – 70% less insulation than similar frame buildings, while still providing an equivalent level of energy efficient performance.

This thermal mass benefit is now recognized in building codes. Stud wall assemblies have much higher requirements than masonry mass walls because of the benefits of thermal mass, which are now quantified in the national energy codes. The advantages include reduction of temperature swings, moderation of indoor temperature, storage of heating/cooling for later release, reduction and shift of peak heating and cooling loads to non-peak hours, and passive solar design.

How Masonry Contractors Are Adapting

Forward-thinking masonry contractors are embracing these changes by incorporating energy-efficient design principles into their work. Energy-efficient designs incorporate proper insulation techniques, strategic use of thermal mass, and passive solar design principles, with a well-designed masonry building able to reduce heating and cooling costs by up to 50%.

Contractors are also focusing on masonry’s thermal mass characteristics that provide optimal heating and cooling efficiency, with masonry walls remaining warm or cool long after the heat or air-conditioner has shut off, reducing heating and cooling loads while stabilizing indoor temperature shifts and exchanging typical peak heating and cooling loads to off-peak hours.

Meeting LEED and Green Building Standards

Many masonry contractors are now positioning themselves to help clients achieve green building certifications. Masonry can help a building meet LEED certification requirements because of its many unique “green” attributes, several of which mirror the basic LEED program categories and include indoor environmental/air quality, daylighting, local material supply, heating and cooling features, and its renewable resource status.

The sustainable aspects of masonry are particularly appealing to environmentally conscious property owners. Masonry is renewable and reusable, with rock and sand in no short supply and easily accessible, thus renewable, while a building’s life speaks to its reusability with the goal being to extend its usable existence.

For property owners seeking a reliable masonry contractor in Boston, MA, Academy Masonry offers the expertise needed to navigate these new energy efficiency requirements while delivering the durability and aesthetic appeal that masonry construction provides.

The Future of Energy-Efficient Masonry

As Boston’s energy efficiency requirements continue to evolve, masonry contractors must stay informed about new technologies and techniques. Masonry materials and wall systems, with their inherent thermal mass characteristics, provide designers with many options to achieve energy-efficient designs, with examples of wall configurations that exceed national building code requirements and high-performance standards.

The integration of thermal resistance requirements for materials installed in wall cavities, with the R-value of integral insulation installed in concrete masonry units considered in determining compliance, and the use of U-factor of concrete masonry units with integral insulation permitted shows how traditional masonry is evolving to meet modern energy standards.

Conclusion

Boston’s new energy efficiency requirements represent both a challenge and an opportunity for masonry contractors. Those who embrace these changes and understand how to leverage masonry’s inherent thermal mass benefits will find themselves well-positioned to serve clients seeking to meet these ambitious green building standards. Companies like Academy Masonry, with their commitment to quality craftsmanship and customer service, are leading the way in demonstrating how traditional masonry techniques can be adapted to meet the demands of a sustainable future.

For property owners planning construction or renovation projects in Boston, working with experienced masonry contractors who understand these new requirements is essential for achieving both compliance and optimal energy performance. The future of masonry in Boston is not just about building structures that last—it’s about building structures that contribute to a more sustainable and energy-efficient urban environment.
