Residential energy modeling

    What are small residential firms using for energy modeling? HEED? Open Studio/Sketchup? Sefaira? Autodesk Insight? Most of our residential work is additions and renovations.

    We use Revit so it would be great to be able to use that geometry, but I wouldn't be opposed to using Sketchup.  I'm not sure such an animal exists, but we would love use one software to; show performance based code compliance, provide 2030 Challenge reporting, test different design options and show clients cost savings by investing in the envelope.

    CoveTool is the best option.

    RE Energy modeling for small firms

    I have found that energy modeling and carbon calculating plugins have restrictions on the host drawing tool. We use Revit LT, which is very powerful - but we don't need / can't afford the full version. The carbon software we wanted to use - Tally - doesn't work on LT, only the full version. We developed work arounds, but ultimately it was too much trouble and expense for us, even though we are committed to low carbon design and motivated by the 2030 Commitment. Still looking for an easier solution to calculating embodied carbon. For now, we reduce concrete, steel, glass and fossil fuel materials, and retrofit to Passive House. Still, I'd love to have some numbers.....

    As a solo practitioner, I'd love to have an affordable, easy-to-use tool. For someone like me, running a dozen projects on my own, it is impossible to learn to use a complicated tool, let alone pay for it. When I contacted Cove Tool about my concerns, how I would use the tool only a few times a year, and how the cost was 10X what I could afford, the response was a deafening silence.

    Another rogue aspect of my firm is that I use Vectorworks, so typical plug-ins built for Revit are lost on me. The industry and this organization need to understand and reflect upon what it takes to run a practice solo and our unique challenges. As fellow architects, being sensitive and not condescending to others in the practice who are "not there yet" would also go a long way. I'm not saying this thread has been condescending, but I often face it from architects, energy testing specialists, and those with more resources than they know what to do within their practice.

    Soap box over.

    Lee I hear your frustration and I agree in the industry it should not be a one size fits all when it comes to software that supports architectural practice. I work for local government and I am fighting for funding so I can provide Revit to my intern who is dying to use it on our projects.

    Andrew, 

    Thank you for recognizing my point and for your kind words. All the best in getting your grant funding.

    Lee, you nailed my frustration as well. I recently attended a Sustainability Symposium, hosted by our local AIA chapter and walked out even more frustrated. When the panel was talking about energy modeling and selecting low carbon footprint materials, it was clear this conversation was for the big firms only. I even asked the panel how this conversation can be applied to smaller firms/projects, and I was literally given the answer, "change the paper towels you use".

    IMHO small to medium sized firms, which are the overwhelming majority of AIA membership, need to work together to push the AIA to represent our needs and advocate for some kind of a public or PPP funded solution to provide our firms this capability. Small scale projects are the overwhelming majority of development in the US (from some CE lectures I have attended it is close to 90%). If our industry wants to really make a difference in climate change, we have to improve the performance of these buildings, and ironically we cannot afford the tools to help change the conversation.
