2019 October 7 Stuff: Regulation Needed To Push Owners To Reduce Fossil Fuels In Buildings, Expert Says

2019 October 5 Stuff: Regulation Needed To Push Owners To Reduce Fossil Fuels In Buildings, Expert Says

“Government regulation will be needed to achieve net-zero carbon buildings says architectural engineering professor Larry Bellamy.” Let’s hope those regulations are good ones that take building physics into account and don’t allow system-wide poor choices. I push energy efficiency every day, it’s what I do, but increased energy requires better building practices and not just stuffing in more insulation. Read …

2019 October 1 Build: Energy Poverty In New Zealand

Paying utility bills is a stretch for many New Zealand households. As we move to a low-carbon economy, a raft of measures may be necessary to ensure that energy costs do not weigh more heavily on those already financially burdened. Analysis using the Household Economic Survey, an annual survey run by Stats NZ that measures the economic wellbeing of New …

2019 September 30 Passive Houses on Energy Efficiency

80-90% heating energy reduction (well for those that could afford to heat their homes) saves energy, CO2 and costs less over the lifespan of the building than building to the legally required minimum (i.e. code). Passive House Pools (Passivhaus) are being built in the UK and were measured to save 70% of the heating energy costs (electricity) in the first …
