Efficiencies at its Kansas facility in 2016 has permitted DaVinci Roofscapes to lower pricing on the company’s roofing products. Price reductions went into effect during the fourth quarter of 2016 and range from 11 percent to 16 percent on several of the company’s synthetic shake and slate product lines.
“Adding more workers and line equipment at our plant along with other advances have enabled us to leverage our operational efficiencies and pass the savings on to our distributors,” says Ray Rosewall, president and CEO for DaVinci Roofscapes. “We’re going outside of the box by sharing our cost savings to make our composite roofing products even more accessible to roofers and owners across the country.”
“We’re conscious of what the market is telling us versus what our competitors are doing. For us, it’s all about advancing the growth of our customer’s business.”
“When DaVinci started manufacturing synthetic roofing tiles about two decades ago they were considered specialty products. Now, thanks to technological advancements our slate and shake tiles are seen more as main stream products. This means we’re very comfortable competing against products like slate, real cedar, asphalt and other materials. From an aesthetic, performance and cost standpoint synthetic roofing products are competitive.”
“Most importantly, we’ve heard from distributors, roofers and builders that our products are becoming preferred to the natural roofing products. People want the expected look of shake and slate, but they want the benefits that a manmade product offers. We’ve achieved that goal by creating realistic-looking products with additional features.”
New molds allowed DaVinci to enhance the look of all of its slate profiles in 2016. The thicker profiles replicate the quarried look of slate at a cost less than natural slate. Thanks to recent price reductions, pricing for the company’s Bellaforté Shake tiles falls below pricing of many real cedar shingles, but with the added benefit of resistance to fire, splitting, curling, mold and algae.
The team members at DaVinci Roofscapes develop and manufacture polymer slate and shake roofing systems with an authentic look and performance. DaVinci offers a selection of colors, tile thickness and tile width variety. The company’s products have a limited lifetime warranty and are 100 percent recyclable. All DaVinci roofing products are made in America where the company is a member of the National Association of Home Builders, the National Association of Roofing Contractors, the Cool Roof Rating Council and the U.S. Green Building Council.
Changes to the purpose and scope that reflect advances in green buildings over the last 10 years are proposed for the high performance building standard from ASHRAE, the International Code Council (ICC), the U.S. Green Building Council (USGBC) and the Illuminating Engineering Society (IES).
ASHRAE/IES/USGBC/ICC Standard 189.1, Standard for the Design of High-Performance Green Buildings, contains minimum requirements for the siting, design and construction of high-performance green buildings in support of reducing building energy use, resource consumption and other environmental impacts while maintaining acceptable indoor environments.
Among them is addenda o, which proposes revisions to the existing purpose and scope of the standard to clarify its intended purposes and application, and to better reflect the revisions to the standard that are being considered by the committee.
Committee chair Andrew Persily notes that the current title, purpose and scope were approved in 2006 and that much has taken place in the world of green buildings in the past 10 years.
Under addenda o, the purpose of the standard has been rewritten to focus on goals vs. strategies. For example, rather than energy efficiency, the goal of reduced building emissions is proposed for inclusion in the purpose.
A new section of the purpose speaks to the alignment of Standard 189.1 with the International Green Construction Code (IgCC), noting specifically that the standard is intended to serve as the technical basis of mandatory buildings codes and regulations for high-performance buildings.
Standard 189.1 currently is a compliance option of the 2015 IgCC, published by the International Code Council, ASTM and the American Institute of Architects. The standard will serve as the technical content for the IgCC beginning in 2018.
Other addenda open for public review until May 8, 2016 are:
- Addendum i reorganizes the roof heat island mitigation section and adds new provisions for vegetated terrace and roofing systems relative to plant selection, growing medium, roof membrane protection and clearances. In addition, provisions for the operation and maintenance of vegetated roofs are proposed for addition to Section 10.
- Addendum n clarifies footnote b to Table 7.5.2A. This footnote provides a method to adjust the percent reduction for buildings with unregulated energy cost exceeding 35 percent of the total energy cost. This addendum clarifies that the adjustment is to be made on the basis of energy cost, not energy use.
- Addendum p proposes to add requirements for water bottle filling stations, which are intended to improve water efficiency and sanitation of public drinking water and to reduce the environmental effects of plastic bottles.
- Addendum r lowers the ductwork pressure testing threshold to include 3-inch pressure class ducts, which are common upstream of variable air volume (VAV) boxes.
- Addendum t adds new requirements for reverse osmosis and onsite reclaimed water systems in order to reduce the likelihood of excessive water use because of poor design of water treatment and filter system.
- Addendum u adds new requirements for water softeners to reduce water consumption given the impact of the design and efficiency of these systems on water discharge water rates.
Open for public review from April 8 until May 23, 2016 are:
- Addendum q modifies Chapters 5, 7, 8 and 11, as well as Appendices A and E, to reflect the addition of Climate Zone 0 in ANSI/ASHRAE Standard 169-2013, Climatic Data for Building Design Standards.
- Addendum s removes the performance option for water use and moves the prescriptive option into the mandatory section.
The Washington, D.C.-based Roof Coatings Manufacturers Association has updated its reflective roof coatings and LEED white paper, originally issued by the Reflective Roof Coatings Institute (RRCI) in 2012. (RCMA and RRCI announced their merger in early 2015.)
The white paper explores the role of reflective roof coatings in the Washington-based U.S. Green Building Council’s LEED Version 4 green-building program with emphasis on new building structure, existing building operation and maintenance, and LEED v4 prerequisites and credit requirements.
The white paper intends to provide understanding for stakeholders about the cost-effective contributions of roof coatings and the environmentally sound new building and renovation projects that use LEED v4. The white paper also serves as a resource, which outlines the benefits that reflective roof coatings provide to buildings, businesses and the environment. The findings in the LEED white paper apply to any reflective roof coatings that are LEED-compliant.
Bob Kobet of The Kobet Collaborative, Pittsburgh, is the author of the LEED white paper updates, as well as RRCI’s original white paper. Members of the RCMA Reflective Roof Coatings Institute, RCMA Technical Affairs Committee, and RCMA Codes and Standards Task Force collaborated on the project to update and revise the white paper to incorporate LEED’s new version.
The COP21 agreement presents a major opportunity for architects around the globe to provide leadership in designing buildings and communities that help reduce greenhouse-gas emissions. Its call for capacity building for adaptation and mitigation of climate change represents exactly what the architecture profession excels at providing,” says Russell Davidson, FAIA, AIA president, as the COP21 meeting of the United Nations Climate Change conference concluded.
In a deal nearly two years in the making, the International Code Council (ICC) and ASHRAE have signed the final agreement that outlines each organization’s role in the development and maintenance of the new version of the International Green Construction Code (IgCC) sponsored by the American Institute of Architects (AIA), ASHRAE, ICC, the Illuminating Engineering Society (IES) and the U.S. Green Building Council (USGBC). The code, scheduled to be released in 2018, will be powered by ANSI/ASHRAE/ICC/IES/USGBC Standard 189.1, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings developed using the American National Standards Institute (ANSI) approved ASHRAE consensus process. The joint Standing Standards Project Committee 189.1 (SSPC) will serve as the consensus body that will work to ensure the standard is consistent and coordinated with the ICC Family of Codes.
The ICC will be responsible for Chapter 1, Scope and Administration. For the 2018 IgCC, ICC will coordinate the technical provisions developed by ASHRAE with the provisions in Chapter 1 of the 2015 IgCC. As a result, the 2016 Group B Cycle will not include Chapter 1 of the IgCC for code changes. With ASHRAE developing technical provisions, ICC’s 2017 Group C cycle to develop the 2018 IgCC has been cancelled. Part of the development process for the 2018 technical provisions will include the SSPC review of the 2015 IgCC and consideration of content for inclusion in 189.1-2017 along with changes generated by the committee and proposals submitted by stakeholders. Following the completion of the 2018 IgCC, Chapter 1 of the IgCC will be developed by ICC using its consensus code development process.
“Our goal in this partnership all along has been to share resources to increase use of the IgCC and make it simpler for code officials, designers and contractors to build environmentally efficient structures that will lessen energy and water consumption and reduce the carbon footprint,” said ICC Board President Guy Tomberlin, CBO. “We are now situated to do just that. We thank our partners, ICC Members and all who will contribute to the development of the IgCC powered by 189.1.”
The Executive Steering Committee for the effort to align 189.1, the IgCC and LEED consists of representatives of ICC, ASHRAE, USGBC, AIA and IES, and the SSPC Chair.
“The full integration of Standard 189.1 to serve as the technical content of the IgCC will leverage ASHRAE’s technical expertise and increase the standard’s influence on sustainable buildings,” notes ASHRAE President David Underwood. “We look forward to continuing to engage a broad spectrum of stakeholders in development of Standard 189.1 following the ANSI consensus standards development process. The result will be a comprehensive compliance tool that can be used by jurisdictions worldwide that are committed to a more sustainable built environment.”
The new publication also will align the Leadership in Energy & Environmental Design (LEED) rating system program to ensure a streamlined, effective set of regulatory and above-code options. The green building certification program recognizes best-in-class building strategies and practices. To receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification
“This joint initiative will forge the fundamental regulatory building blocks of green construction on which future green building leadership initiatives can grow,” says Brendan Owens, chief of engineering at USGBC. “It takes courage to think differently and to commit to a new model, and for that we thank the leadership of the partner organizations behind the IgCC powered by 189.1.”
“Our combined membership, consisting of practicing design professionals, code officials, and the building industry representatives, supports the development of codes and standards that protect the health, safety and welfare of the public at large,” says AIA CEO Robert Ivy, FAIA. “Through this significant agreement, both the AIA and the ICC agree to work more closely to achieve our common goals.”
In 2010, ASHRAE and ICC joined forces by making 189.1 an alternative compliance path for the IgCC. The new agreement between ASHRAE and ICC furthers the effort these organizations initiated in 2010 by providing the market with a single code that is coordinated with the International Family of Codes.
“IES looks forward to continuing to partner with ASHRAE in developing technical content for Standard 189.1,” according to Rita Harrold, IES representative. “And to participating with the other organizations in this unique collaborative opportunity to satisfy the goals for the new version of IgCC.”
The agreement creates a comprehensive framework for jurisdictions looking to implement and adopt green building regulations and codes. The unprecedented collaboration leverages the unique organizational expertise of the partners participating in this evolution of green building codes and brings AIA, ASHRAE, ICC, IES and USGBC into strategic and tactical alignment on the relationship between 189.1 and the IgCC. Other organizations that support this vision and would like to join the effort are invited to contact Dominic Sims or Jeff Littleton.
