RELi is a building-resilience framework that connects climate adaptation and mitigation, biodiversity, and social equity. For an owner or facilities team, its most useful lesson is procedural: start with a site-specific risk assessment, then select measures that protect occupants, preserve critical operations, and support the surrounding community. Do not treat a resilience standard as a universal checklist.
RELi’s current version and maintenance status are not established by the available official information. The February 6, 2019 BUILDINGS feature described a planned RELi 2.0 that was expected to align with LEED pilot credits and add a point-based credit catalog. That description is historical, not confirmation that the planned release occurred or remains current.

What RELi means in building design
RELi is presented as a resilience-focused standard for buildings and facilities. Its scope is broader than structural resistance to a single event. The framework links three fronts that are often managed separately:
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →- Climate mitigation and adaptation: reducing contributions to climate change while preparing for changing hazards and conditions.
- Biodiversity: considering how a project affects and depends on living systems, landscapes, and ecological functions.
- Social equity: recognizing who relies on a facility, who is most exposed during a disruption, and which resources a project can share with its neighbors.
Doug Pierce, an architect at Perkins+Will and principal investigator on RELi’s development, described the reason for this integrated approach: “There’s no one right answer for everyone.” A hospital, school, manufacturing plant, apartment building, and public library can face different hazards, serve different populations, and have very different consequences when they close.
#1 Best Overall
- Valued Carpenter Pencil Set: You will get 2 pcs solid carpenter pencils with 26 piece 2.8 mm refills, 1 replaceable sharpener, 1 plastic storage box.The complete carpenter pencils combination allows you to finish your work faster and more easily
- Deep Hole Marker Pencil: The deep-hole construction pencils adopts 45mm elongated tip design, which is more convenient to mark in the small hole or in other tight areas that other carpenter markers cannot reach
- Carpenter Pencils with Sharpener: The sharpener is screwed into the top of the work pencil, which won't get lost either. Built-in pencil sharpener that keep the lead with pointed and smooth to Improves line of sight in fine work
- Stronger Solid Lead: This work pencil is matched with a 2.8 mm thick lead , which is much thicker and stronger during the drawing process of construction work, it will not break or damage easily
- Marks on Various Surfaces: 3 colors solid construction pencil can marks on various surfaces,such as metal, plastic, wood, paper etc. Ideals for woodworkers, contractors, craftsmen, builders, merchants and masons
RELi therefore works best as a way to organize decisions rather than as a substitute for engineering analysis, code compliance, emergency management, or continuity planning. A project team still needs qualified professionals to assess structural, electrical, mechanical, fire, flood, geotechnical, environmental, and accessibility conditions.
What the RELi 2.0 proposal actually established
The 2019 article reported that RELi 2.0 was expected to align with LEED pilot credits and introduce a credit catalog with a point system. That was a report of a planned update during the standard’s pilot phase. The source does not establish that version 2.0 launched as described, what credits it ultimately contained, or whether it is maintained today.
Use that distinction when writing specifications, setting owner requirements, or making certification claims. A project team can use the article’s resilience principles, but it should verify any current edition, definitions, prerequisites, scoring rules, or certification pathway directly with the standard’s current administrator before relying on them contractually.
Why a single disaster checklist fails
A generic list might tell every building to install a generator, elevate equipment, add flood barriers, or increase enclosure strength. Those actions can be valuable in the right setting and wasteful or counterproductive in another. A generator may preserve a critical service but create fuel, ventilation, noise, maintenance, and emissions obligations. A seawall may reduce one coastal exposure while shifting water or ecological impacts elsewhere. Operable windows can provide passive survivability during a power outage, but only where outdoor air quality, security, acoustics, humidity, and occupant needs make them workable.

Resilience decisions must account for the facility’s hazards, operating schedule, recovery objective, occupants, available alternatives, and community role. Ariane Laxo, a resilient-design leader and interior designer at HGA, put the desired process this way: “We want to have risk conversations holistically so we can look at all the risks together, not making separate lists of things we need to consider in design.”
How to assess a building’s resilience
Begin before choosing equipment or writing a credit checklist. Bring the owner, facilities staff, design professionals, security, landscape, stormwater, information-technology, human-resources, emergency-management, and continuity representatives into the same assessment. Use local hazard-mitigation plans and relevant organizational plans as inputs, then test their assumptions against the actual site and operation.
- Define the facility’s mission. List the services the building provides, the functions that are safety-critical, and the functions that can pause. Record operating hours, seasonal changes, staffing patterns, storage needs, and dependencies on utilities, communications, transportation, vendors, and data systems.
- Map site-specific hazards. Consider the hazards that can affect this parcel and its access routes: flooding, extreme rainfall, coastal or river water, heat, cold, wildfire smoke or fire, wind, utility interruption, security incidents, and other locally identified threats. Distinguish direct damage from loss of access, unsafe indoor conditions, and supply-chain disruption.
- Set recovery and survivability objectives. Decide how quickly each function must resume, which spaces must remain usable during an outage, and how long occupants may need to stay when evacuation or relocation is not practical. A facility that must operate continuously needs a different strategy from one that can close for several days.
- Identify occupant and user needs. Account for mobility, medical, sensory, language, age, and caregiving needs. Determine whether occupants can work or shelter elsewhere, how visitors are supported, and what happens when elevators, ventilation, lighting, water, or digital systems fail.
- Examine community context. Identify nearby populations, public services, vulnerable groups, evacuation constraints, and resources that could be shared. Ask whether the building can provide useful space, power, cooling, information, water, or other support during ordinary periods and a crisis.
- Rank risks by consequence and likelihood. Document the evidence behind each ranking, including maps, historical events, utility information, engineering studies, and operational records. Separate high-consequence low-frequency events from frequent lower-severity disruptions so neither category disappears.
- Test interdependencies. Model combinations rather than isolated failures. For example, a storm may interrupt power, disable pumps, block roads, prevent staff from arriving, and overload communications at the same time.
- Select and sequence interventions. Compare options against the ranked risks, recovery objectives, maintenance capacity, cost, environmental effects, and community benefit. Identify interim actions and a long-term capital plan.
- Exercise and update. Train staff, run tabletop and operational drills, inspect equipment, and revise the assessment after projects, incidents, code changes, or changes in climate and occupancy.
Choosing resilience measures by facility need
The following examples are possibilities, not universal RELi requirements. Each should be justified by the assessment and designed for the building’s actual use.
| Measure | Potential value | Questions before adoption |
|---|---|---|
| Backup power | Maintains selected life-safety systems, communications, refrigeration, controls, or mission-critical equipment during an outage. | Which loads are essential? What is the fuel or energy source, runtime, refueling access, noise limit, emissions impact, testing schedule, and safe connection method? |
| Operable windows and other passive-survivability features | Can provide ventilation, daylight, and limited thermal relief when mechanical systems or power are unavailable. | Are outdoor air, smoke, heat, humidity, security, acoustics, and accessibility conditions acceptable? Which rooms and occupants can use the feature safely? |
| Flood protection, including a seawall where appropriate | May reduce exposure to coastal or water-related hazards at a site with a documented need. | What design event and future conditions are being addressed? Could the measure redirect water, damage habitat, restrict access, or create a false sense of security? |
| Expandable geothermal capacity | Can allow a project to increase low-carbon heating or cooling capacity as loads, phases, or technology change. | Is the geology suitable? What space, drilling access, controls, financing, maintenance, and future load assumptions support expansion? |
| Community-use spaces and resources | Can support neighbors during normal periods and provide a place, service, or resource during a crisis. | Who operates the space, under what agreements, with what staffing, security, accessibility, insurance, supplies, and communications? |
The right comparison is not simply “Which upgrade is most resilient?” Evaluate each option against the hazard it addresses, the facility’s function and occupancy, the time needed to resume operations, occupant safety during interruptions, site and community context, and the evidence supporting the assessment.

Integrating climate, biodiversity, and equity
Climate adaptation and mitigation
Adaptation protects people and operations from present and anticipated hazards. Mitigation reduces emissions and resource impacts that contribute to longer-term climate risk. Decisions can serve both goals, but not automatically. A resilient power system, for example, should be evaluated for fuel use, emissions, maintenance, and the conditions under which it operates. Passive design, efficient systems, durable materials, and renewable or low-carbon energy may reduce operating impacts while improving performance during some outages.
Biodiversity and site systems
Landscape, drainage, soils, vegetation, and habitat can influence flooding, heat, erosion, and water quality. Include these systems in the same risk conversation as the building envelope and mechanical plant. Avoid assuming that a hard barrier is always the best answer; assess how a proposed intervention affects upstream and downstream conditions, ecological functions, maintenance, and future hazards.
Social equity and useful shelter
Equity means asking who benefits from the project and who bears the risk when it fails. A facility may be a workplace, school, care setting, or neighborhood resource. Spaces and resources that are useful every day can be easier to activate in an emergency than a room reserved only for disasters. Planning must still address staffing, access, safety, privacy, language, transportation, and the limits of what one building can provide. A single project cannot resolve wider inequities or biodiversity loss, but it can avoid increasing them and can strengthen local capacity.
Organizing the project team
Resilience work often fails at the boundaries between disciplines. Security may plan for threats without coordinating with landscape or access design. Stormwater improvements may proceed without facilities staff who will maintain them. Continuity planners may set recovery objectives without knowing how long replacement parts or specialist contractors take to obtain.

During planning and programming
Set mission, occupancy, recovery, and community objectives before selecting a rating target. Gather hazard maps, utility data, previous incident reports, insurance requirements, and local mitigation plans. Include resilience requirements in the owner’s project requirements and confirm who will verify them.
During design
Use scenario workshops to examine single and compound hazards. Develop options with capital, operating, maintenance, environmental, and community consequences visible. Design for inspection and replacement, not just initial performance. Preserve access to critical equipment and document manual operating modes.

Common mistakes and how to correct them
- Applying a generic checklist: Replace it with a documented, site-specific risk assessment tied to mission and occupancy.
- Counting equipment as resilience: Define the service the equipment must provide, the duration, operating procedure, maintenance, and failure mode.
- Planning for one hazard at a time: Test compound events such as extreme rain plus power loss and blocked access.
- Ignoring recovery: Set explicit restoration times and identify alternate locations, staff, vendors, data, and transportation.
- Leaving community needs until the end: Identify useful spaces and responsibilities during programming, not after construction.
- Assuming a standard is current: Verify the active RELi edition, administrator, definitions, and certification rules before making a compliance claim.
- Failing to maintain the solution: Fund inspections, exercises, replacement parts, training, and updates as part of the project rather than as optional extras.
What to document for defensible decisions
Keep a concise resilience record that another facilities manager can use years later. It should identify hazards and sources, assumptions, critical functions, recovery objectives, selected and rejected options, design loads or scenarios, responsible parties, maintenance requirements, inspection results, training records, and unresolved risks. Record why a measure was not selected; a lower-cost or lower-impact option may be appropriate when it meets the stated objective.
Use measurable operational questions where possible: How long must critical loads run? Which rooms must remain safe? What temperature, air-quality, water, or access conditions trigger relocation? Who authorizes shutdown or reopening? What evidence confirms that the building is ready? These questions turn resilience from a slogan into an accountable operating practice.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteThe practical takeaway
RELi’s enduring contribution is the insistence that disaster-ready design is not a universal package of products. It is a coordinated process that connects hazards, operations, occupants, ecology, and community. The 2019 account of RELi 2.0 should be read as historical planning, while any current edition or certification claim must be verified separately. For a building owner, the sound first move is a comprehensive risk assessment; every backup system, passive feature, flood intervention, or community resource should follow from that evidence.
