Development of a whole-house energy rating tool for new housing

In 2019, Australian energy ministers agreed on the need for the Trajectory for Low Energy Buildings (the Trajectory). One of the key aspects in the Trajectory for residential buildings is to expand the Nationwide House Energy Rating Scheme (NatHERS) to offer nationally accredited whole-of-home (WoH) tools to enable compliance requirements in the National Construction Code (NCC).

Streamlining electrification in support of decarbonisation

Our industry has increasingly focused on the electrification of building utilities coupled with low-carbon electricity to support the global decarbonization effort. Examples include the University of California’s system-wide ban on the use of on-site fossil fuel combustion in new construction and major renovations, and the City of Seattle’s recently passed measure to prohibit the use of natural gas for space heating in new construction and major replacements of heating systems in commercial buildings, as well as for water heating in new hotels and
large apartment buildings. This column presents an approach to integrating the production of domestic hot water with an electric heat-recovery chiller plant as a streamlined solution.

Feasibility study of wastewater energy transfer for an existing campus building cluster

The HVAC-related energy usage of a group of three existing buildings on a Canadian university campus (the “Cluster”) was simulated. Two scenarios were compared: (1) an ambient loop paired with conventional HVAC equipment (boiler plant and cooling tower), and (2) an ambient loop using wastewater energy transfer (“WET”). The study aimed to assess the feasibility of implementing WET as a heating and cooling method for cold-climate institutional buildings, as well as to measure the effects of WET implementation on energy usage, greenhouse gas emissions, and energy costs

Rewards program

Rewards program

Recognising performance that goes above and beyond doesn’t always have to be expensive, writes Dr Gayle Avery. But it does have to be executed properly and appropriately.You’d think that using rewards would be a cinch – just give someone some money or something else...
