The presentation will provide a refresher on the framework of sustainability and historic preservation, and will provide an introduction to roofing challenges and questions, and the general approaches recommended by the National Park Service. This presentation will primarily provide preliminary information, identify challenges specific to Fort Collins and northern Colorado, and suggest questions and research avenues to develop updated best practices in this area. Staff is seeking input from the Commission regarding this topic regarding future design review decisions under Chapter 14. ATTACHMENTS 1. Staff Presentation Packet Pg. 3 1 Historic Preservation & Sustainability Section 2 – Roofing Introduction Jim Bertolini, Historic Preservation Planner Landmark Preservation Commission Work Session, January 8, 2020 Goals of Sustainability Workshop • In General • Staff introduction to topic and preliminary questions • LPC encouraged to discuss, ask questions, and provide expertise on the subject • Topic-specific goals: • Explain current regulatory framework for roofing on historic buildings in Fort Collins • Inform LPC and attending public about how the City’s sustainability goals intersect with historic preservation goals regarding roofing. • Capture information from LPC members about best practices and products on roofing. • Return to LPC at future work session with results of additional research and, if needed, proposed new approach to roofing permits. 2 1 2 BOARD TOPIC 1, ATTACHMENT 1 Packet Pg. 4 Sustainability - Definitions • “Triple bottom line” approach •Social • Connect people with history • Consider owner/resident needs (rehabilitation) • Consider local knowledge & craftsmanship • Economic • Boosts to local job growth • Small business incubation • Financial solvency for local governments in pedestrian-focused environments • Environmental • Embodied energy • Reduce, reuse, recycle (in that order) 3 Society Environment Economy Embodied Energy • Buildings have two significant energy costs 1. Construction 2. Operations (lighting, heating, etc.) • Embodied energy includes full supply chain • Costs of raw material extraction • Costs of material manufacture/processing • Costs of transportation • Costs of physical construction • Best practice to consider demolition energy costs as well • Many historic buildings, especially masonry buildings, can meet LEED requirements for operational energy efficiency. 4 Materials - Architectural 50% Materials - Utilities 20% Fuel & Transport 17% Business Services 11% Furnishings 1% Machinery 1% Typical Embodied Energy Distribution U.S. Dept. of Energy, Energy Use for Building Construction. 3 4 BOARD TOPIC 1, ATTACHMENT 1 Packet Pg. 5 Planning Concepts & Strategies • Conduct an energy audit first (solve problems a building actually has) • Consider inherent energy efficiency of the building • Reuse of existing materials is generally more energy-efficient than replacement due to: • environmental costs of manufacture • durability of historic materials (especially pre-1950) • No such thing as “maintenance free” 5 Where Air Escapes From a House (by percentage) – Image based on data from Energy Savers, U.S. Department of Energy. Illustration: Blank Space LLC. Passive Approaches – Roofs • Roofs are a critical element for building health and energy efficiency • First line of defense for weatherization • Key factor in building airflow • Must be insulated but ventilated 6 National Park Service 5 6 BOARD TOPIC 1, ATTACHMENT 1 Packet Pg. 6 Preservation Approaches - Roofing •NPS • Preservation Brief 4 • Standards generally recommend retaining historic material • Acknowledge substitute materials as potentially appropriate where cost & community goals may conflict with retaining historic material 7 Old House Web Roofing – Design Review • Design Review – Fort Collins HPS • Staff Review (expedited) • Typically approved (or denied) within 48 hours of permit desk receiving application. • Landmarks/Landmark Districts – no change in material allowed (in-kind replacement required) • NRHP/SRHP properties – change in material strongly discouraged • Typically, LPC will not see roofing unless it is an appeal of a staff denial 8 7 8 BOARD TOPIC 1, ATTACHMENT 1 Packet Pg. 7 Roofing – City Code Requirements • Modern Fort Collins code requires: • Class IV shingles (impact resistant) • Adequate slopes and/or drainage • Underlayment and flashing • Drip edge (asphalt shingle) • Ventilation • Ice barrier at least 24 inches beyond interior edge of exterior wall (more for steep roofs) • Wood shingle roof system must be Class B or above (fire rating) • Chemically treated w/ fire retardant • Rated for commercial/multi-family use 9 Roofing – Historic Fort Collins materials •Wood • Typically, the first shingles on any residential building (and some commercial) • Some remain, either under asphalt or as the top layer • Asphalt • Most common material • Rolled/membrane or shingle • Began to replace wood beginning in 1930s • Some new products mimic wood shingles • Metal or Clay • Uncommon, at least on older construction • Often used on older commercial buildings (late 1800s to early 1900s) 10 9 10 BOARD TOPIC 1, ATTACHMENT 1 Packet Pg. 8 Roofing – Fort Collins Challenges • Sustainability goals (Zero Waste) • Disposal is problematic • Metal • Easy to recycle • Challenge – appropriateness on historic buildings • Hail damage • Climate change & storm intensity • Higher frequency of roof replacement • Rehab • Ventilation • Inadequate in many older buildings • Additions and alterations • Owners often need to add windows/dormers to meet ingress/egress code 11 Disposal • Roofing comprises a significant amount of Larimer County landfill every year, especially in 2019 • Difficulties in recycling • Wood (fire retardant) • Asphalt (limited demand) • Metal is the most recyclable • May not be historically appropriate • New products mimic wood or asphalt • Stone, polymer, or rubber coating • Typically require distance to blend 12 11 12 BOARD TOPIC 1, ATTACHMENT 1 Packet Pg. 9 Regional Approaches to Historic Roofing • Longmont – strongly recommends replacement in-kind • Approach depends on whether roof is character-defining • Typically require in-kind on architecturally- significant homes; allow switch to asphalt if not • Denver – allows substitute materials • If replacing wood, need brown-colored asphalt • Allow for synthetic wood (asphalt, slate) • Greeley – allows for substitute materials (discouraged) • Low-profile asphalt allowed to replace wood shingles 13 • Boulder (City) – allows for substitute materials in some circumstances • Wood must be phased out • Asphalt shingle considered appropriate • Require preservation of material (non-wood) if character-defining • Boulder County – phasing out wood shingles/shakes (fire concern) • Loveland – substitute materials allowed • Wood must be phased out • Have approved substitutes that mimic wood (polymer) In general, substitutes are allowed in other northern Colorado preservation programs, but reasons and limitations vary Questions • What new approaches should the City consider regarding roofing on historic buildings? • Should substitute materials be permitted? • If so, what factors should determine when this is appropriate? • What limitations should be placed on substitutes? • What types of substitute materials should be entertained, considering the City’s holistic goals for preservation of historic materials and waste reduction? • On what avenues for research should staff focus? • Substitute materials (regional use and effects on historic integrity) • Cost reduction methods • Code waivers or other approaches to enforcement in other communities • What should the LPC’s role be in roofing considering time constraints? 14 13 14 BOARD TOPIC 1, ATTACHMENT 1 Packet Pg. 10 Board Topic 2, Page 1 DATE: STAFF: January 8, 2020 Karen McWilliams, Historic Preservation Manager WORK SESSION ITEM 2 Landmark Preservation Commission SUBJECT FOR DISCUSSION LPC Work Plan - Progress and Priorities EXECUTIVE SUMMARY City Code requires all boards and commissions to file work plans on or before September 30 for the following year.
