In the context of decarbonization, buildings are often talked about as if they exist in a vacuum, where any technical approach that eliminates fossil fuels -- particularly electric heat pump conversions -- is viewed positively. The reality is that buildings are connected to an electrical grid which, at any point in time and at every connection, has strict physical limits on how much electricity can be generated and transmitted. As many studies have concluded, large-scale building electrification that increases demand cannot happen without massive expansion of the grid which will take decades and hundreds of billions of dollars to realize. Here is one of many, many examples (from a Boston source!): https://www.bu.edu/sph/news/articles/2022/inefficient-building-electrification-risks-prolonging-fossil-fuels/. Making this problem even more challenging is the parallel electrification of the vehicle fleet. Not to mention that inefficiently electrified buildings also require more renewable energy power, which will slow even further the transition to a 100% renewable power system. What is needed is an electrification approach that does not increase demand and, preferably, also does not increase electricity use. And if that approach happened to also provide occupant comfort and health benefits, that would be amazing. Such an approach exists. We call it VHE HVAC (Very High Efficiency HVAC) and it has been successfully installed and validated in twenty buildings (and counting). In Tarrytown, NY a 71,000 sf office building replaced 24 gas-fired rooftop units with a VHE HVAC system. Natural gas use fell by 97%, electricity use was reduced by 34% and peak demand was reduced by 25% with the results validated by Pacific Northwest National Laboratory. Multiple other examples exist of buildings that achieved these types of results. Another large benefit of not increasing demand is that no upgrade is required for the building electrical service. Upgrades are extremely expensive and can often make an otherwise appealing project uneconomical. VHE HVAC is not a specific product or technology. It is a performance-based, technical specification that optimizes the entire HVAC system. The non-proprietary specification is less than two pages long and can be viewed at imt.org/vhehvac/spec. The approach uses high efficiency versions of equipment that are widely available through multiple manufacturers, including all of the major heat pump manufacturers. The equipment is familiar to industry designers and installers so the approach can be replicated and scaled without requiring extensive, specialized training. Getting the word out about electrification that does not increase demand is incredibly important in not just achieving the ultimate goal of a carbon free economy, but doing it as quickly as possible.
