Building 7-Gen Communities
using electrification, and tight building envelopes.
To meet the IPCC target of limiting global warming to 1.5 °C above pre-industrial levels, the world will have to curb carbon emissions by at least 49% by 2030, and then achieve carbon neutrality by 2050. Natural gas is the primary heating fuel for most buildings constructed today.
With a life cycle of 60-100 years, these buildings will be forced to retrofit to cleaner energy sources in order to meet IPCC targets. Add in increasing taxes on natural gas, pricing volatility, methane leaks arising from its distribution, and the health costs of combustion byproducts, and it should be apparent why our 7-Gen Communities are built with zero-gas energy sources.
Because it is a rare electricity grid that runs without some fossil carbon feedstocks, where practical, we go a step beyond mere electrification and install distributed energy systems powered by renewable sources such as solar energy.
Clean energy sources are complemented by a well-designed, tight building envelope. This includes high-efficiency window insulation, and air-source heat pumps to generate heating and cooling. ERV (energy recovery ventilator) technology rounds out the picture to keep these buildings healthy as well as efficient.
