New Air Tightness Record in Ontario (Dare I say Canada?)

It happened again yesterday: a new record (tell me if you know of a tighter house in Ontario if not Canada!) for air tightness was broken in Oakville by Certified Passive House Consultant (CPHC) Ed Marion of Passive House Ontario.

And this was just a pre-drywall test, so it can only get better from here.…

The House of Mystery

Sometimes we forget how complicated a house is. Building scientists know all about a house’s complexity because, even with help from supercomputers, they still can’t reliably simulate many of the processes taking place, let alone model the whole house. Perhaps the biggest challenge is that the darn thing can’t keep still. Cycles with different periods impose their wills on the structure and equipment in not entirely predictable ways. The seasons impose annual cycles for the sun and average…

GeoSpring HPHWH from GE

Most homes in this area have a gas fired natural draft hot water heater. They come complete with a draft diverter.  The purpose of the draft diverter is to send the exhaust gasses (containing Carbon Monoxide, Sulphur Dioxide etc) into the home if the chimney or flue doesn't allow them to go up. Left is a picture of a properly installed heater with a draft diverter. Note the space between the tank and the flue. That is the design that allow the noxious gasses to back draft into the…

Are you able to justify your Energy Management investments?

No business can afford to waste money. Each one is held accountable for how it spends financial resources. Enterprise-level companies in particular are under constant pressure to lower total cost of ownership (TCO) of assets and justify investments in the context of Cost, Profitability, Productivity, and Sustainability.

Improved energy efficiency is by far the single largest unleashed opportunity to reduce TCO across the enterprise. For example:

  • In…

5 Things New Energy Efficiency HVAC Contractors Need to Know

1. Do not sell on Price! Use 'Simple Payback'

The price of High-efficient equipment will undoubtedly cost more money up front, compared to the minimum efficiency systems. Taking into account existing repair bills, utility bills, installation, and equipment costs, a high-efficient furnace, boiler, or heat pump will cost the homeowner less over the estimated 10-15 years of operation. When completing the 'Simple Payback' calculation, the high-efficient heating system in New England will… Continue

A call to Builders and Architects: Does the Homeowner Know You’re a Blowerdoor Virgin?

When setting out to build an efficient house, the elephant in the room is air tightness. Industry is resisting mandated air tightness testing if thresholds are introduced meanwhile building codes are ratcheting up efficiency on all fronts except air tightness. Having debunked the myth that “a house needs to breath” its becoming painfully obvious to any building scientist that the lowest hanging fruit on the efficiency tree isn’t geothermal but simply producing a more air tight…

Could a Certificate Motivate Homeowners to Invest in Efficiency?

80 percent of Minneapolis’s housing stock was built before World War II, but 40 percent of these homes have never upgraded their wall insulation. After investigating barriers to completing efficiency projects, CEE’s latest report, Energy Fit Homes, proposes awarding a certificate to homes that achieve basic efficiency standards.
