Creating Healthy, High-Performing Spaces for a Sustainable Future

Energy Modeling • Carbon Accounting • Whole Building LCA

  • Carbon Accounting

    Reduce your project’s carbon footprint by tracking the embodied carbon of material selections through Whole-Building Life Cycle Assessment (WBLCA). This approach is essential for understanding the full environmental impact of buildings and products—especially in the construction sector, where embodied emissions can be significant.

  • Energy Modeling

    Using the PHPP (Passive House Planning Package) energy modeling tool, a wide range of factors, such as building geometry, insulation levels, airtightness, window performance, solar gains, internal loads, and ventilation systems, are analyzed to accurately predict a building’s energy use, heat loss, and overall thermal comfort.

  • Feasibility and Cost Consulting

    Align your project goals to your budget with a feasibility assessment of your sustainable build to ensure the desired design outcome is achievable from the beginning .

  • Sustainable Construction Management

    First time building passive? We can help with on-site support for construction teams executing high performance projects as well as provide documentation for certification.

My Approach

Custom Home with Cottonwood Custom Builders, Inc.

To me, building wellness means focusing on energy efficiency, designing for net-zero carbon, taking into account the embodied carbon of selected materials, incorporating locally sourced building materials, while designing a building envelope that is air tight and vapor resistant and incorporating fresh air exchange for maximum health of the building and its occupants.

Feasibility

A Passive House feasibility study is an essential step in determining whether a building project can effectively meet the Passive House standard, which is a rigorous, voluntary standard for energy efficiency in buildings. This study evaluates the technical, economic, and environmental considerations involved in constructing or retrofitting a building to meet Passive House criteria.

A PH Feasibility study includes PHPP energy modeling to simulate the building’s energy performance, building envelope evaluation which looks at the effectiveness of insulation, airtightness, and thermal bridge reduction, and mechanical systems assessment.

Cost Consulting

Accurate cost estimation can make or break a project. I ensure accurate cost estimating that considers the diverse materials and technologies needed to build a high performance home. My many years of experience estimating commercial and residential projects supports the passive house approach by ensuring the design stays on budget from inception to completion.

My open book approach allows my clients to see all direct costs by line item with a variable contingency and markup clearly noted. Oftentimes, conceptual budgets are within 5-10% of the final construction contract if major design changes aren’t incurred.

  • What people are saying...

    "We had the pleasure of working alongside Karen Ramsey on a large renovation for a home in Boulder, Colorado. Karen was wonderful to collaborate with and she quickly adapted to and delivered on our design needs for the home.  She delivered high-quality work under tight deadlines and consistently demonstrated professionalism, skill and commitment to the success of the project.  We would be so happy to work with her again in the future!”
