AWARE of CDC and NIH guidelines

The Baseline Property Condition Assessments described in ASTM E2018-15 do not specify consideration of infectious disease transmission concerns. In a pandemic and post-pandemic environment, that inspection and documentation is essential.

Buildings open to the public must comply with local regulations. For best results and greatest public acceptance, any planning for building repairs and maintenance should not overlook current CDC and NIH guidelines.

Optionally, ecoPreserve's can assist with a comprehensive GBAC STAR™ Accreditation which extends beyond the building to include the goals, actions, equipment, and supplies needed to implement best practices for outbreak prevention, response, and recovery.

Tools tailored to location and need

Disaster resilience requires a select toolset, identified, adapted, or created as needed based on planning calls and inclusive workshop participation.

Business and government organizations today are confronted by threat categories that range from drought to flood, from fire to hurricane, and extend globally to pandemics and sea level rise. Threat categories are broad and diverse, but ecoPreserve and collaborating organizations design resiliency tools for specific local context.

Local needs are identified and verified. Building from that essential understanding, tools are designed, tested in pilot programs, refined, then implemented through action plans.

Today's challenges/
tomorrow's potential

ecoPreserve collaborates with major community and private organizations in optimizing the resiliency and resource efficiency of their workplaces, venues, and public spaces.

In response to ever-increasing environmental, sociopolitical, and public health challenges, we advocate for and participate in assessment and planning actions that directly address disaster preparations, recovery activities, infrastructure improvements, and smart building/city design.

Online and in-person workshops

ecoPreserve designs and leads workshops in varied formats, to achieve varied goals.

Often an event is held for skill and knowledge development, but some needs of an organization or community are better resolved through collaboration to identify requirements and to design solutions. A range of Disaster Resilience workshops are available for solutions planning and development, as well as for training and communication.

Disaster Planning and Recovery Workshops

  • Identify technical and business process gaps
  • Define stakeholders, recovery teams, and processes/functionalities necessary for operation
  • Highlight missed expectations from a data loss and recovery time perspective
  • Address compliance with regulatory agencies and industry standards

An OPTIMIZED Assessment

Certified Sustainability Consultants on a facility assessment team can discover ways to lower energy costs. Their understanding of HVAC equipment suitability and condition along with the specifics of LED lighting retrofits can provide offsets for needed investments in upgrades and replacements.

Knowledge of water systems can bring further savings while averting water waste. It can all be part of an assessment which might otherwise overlook water fixtures and irrigation schedules.

How should a facility be ASSESSED?

A thorough facility assessment finds the issues - on the surface or below - which have a potential negative impact on the building. That brings the facility to meet building codes. Beyond that, the assessment proactively addresses the deficiencies not covered by code.

The occupants of a building benefit as the assessment reveals conditions having a potential impact on their health or safety. The assessment must not overlook those conditions, nor fail to consider the frequency and duration of occupant visits.
