Building automation: energy savings, KNX case studies and companies?
High-quality building automation typically saves 30-40% of the energy needed for lighting, heating and cooling a building. This matters amidst energy shortages, and reduces payback times on $100-500k up-front capex. This data-file aggregates case studies of KNX energy savings, and screens 70 companies, from Capital Goods giants to private pure-plays.

Cool customers: AI data-centers and industrial HVAC?
Chips must usually be kept below 27ยบC, hence 10-20% of both the capex and energy consumption of a typical data-center is cooling, as explored in this 14-page report. How much does climate matter? What changes lie ahead? And which companies sell into this soon-to-double market for cooling equipment?

Average home sizes: living space per person?
Average home sizes matter for overall residential energy demand, heating and cooling demand. Hence the purpose of this data-file is to aggregate average home sizes by country, then translate the data into living space per capita. A good rule of thumb is that each $1k pp pa of GDP translates one-for-one into 1m2 pp pa…

Global heat pump sales by country?
Global heat pump sales by country are tabulated in this data-file, for 14 countries/regions. Developed world heat pump sales rose at an 11% CAGR over the decade since 2012, reaching 7M units sold in 2022, but then unexpectedly fell by -10% in 2023, including YoY declines in 7 out of the 14 countries we are…

Electric vehicle cost breakdown by component?
This data-file disaggregates the $30k total cost of a typical new ICE and the c$45k total cost of a typical new EV, as a sum-of-the-parts, across 25 cost lines. Drivetrain costs are similar at $8-9k each. The key challenge for the EV is the battery. The electric vehicle cost breakdown shows promise for improving power…

Superconductor screen: projects, materials, companies?
This superconductor screen summarizes all of our work into superconductors, screening past projects, active companies, superconductor materials and the properties of commercial HTS tapes. Five listed companies in Europe, Japan and the US are particularly important for superconducting cable projects to relieve grid bottlenecks?

LNG plant compression: gas drives vs electric motors?
This data-file compares the costs of refrigerant compression at LNG plants, using gas turbines, electric motors powered by on-site CCGTs, or electric motors powered by renewable electricity. eLNG has higher capex costs, but higher efficiency, lower opex, and short payback times. Numbers in $/mcf and $/MTpa can be stress-tested in the data-file.
