Energy efficiency for heating, ventilation and air conditioning (HVAC) systems in commercial buildings • Proposal 4. Natural light for higher-density housing • Proposal 5. Weathertightness testing for higher-density housing • Proposal 6. Standards referenced in B1 Structure • Proposal 7. Editorial changes to Acceptable Solution B1/AS1
- 11. Maximum delivered electricity (kWh/m2 /year) associated with operational energy (excluding appliances) for each star rating
- 14. “British Columbia’s ongoing experiment is demonstrating that if builders are given a long lead time for a high-performance level and interim thresholds, and given adequate supports, they will step up to the task.” 1. Prioritise the envelope 2. “Let the leaders lead” 3.

- 16. “The current New Zealand Building Code (NZBC) does not provide a strong link between operational efficiency and defined health and wellbeing parameters (eg internal temperatures).”
- 17. “Our vision is by 2035, New Zealand’s new buildings are using as little energy and water as possible. They are warmer, drier and better ventilated, and provide a healthier place for us all to work and live.).” Transforming Operational Efficiency: 1. Energy use 2. Water use 3. Health and wellbeing

Editor's Notes
- #13: TUI – a measurement of total usage intensity 1 kWh / sqm*yr = 1 TUI TEDI – a measurement of thermal energy demand intensity

- #18: “The most significant operational carbon emissions are the indirect carbon emissions from the use of electricity and water when we live and work in buildings. Operating buildings also contribute direct carbon emissions, mainly through burning fossil fuels to provide heating and hot water.” “Approximately 20% of all energy in NZ3 is consumed in the operation of buildings and around 65-70% of the energy consumed in buildings is in the form of electricity. Buildings use slightly more than half of the electricity produced in NZ.” “A considerable amount of potable water is used in buildings and a similar amount of wastewater comes from building use. Treatment and transport of potable and waste water, and related activities by water service providers, contribute indirect emissions mainly through the use of electricity4”. “Water supply is already strained in parts of New Zealand and this situation is predicted to worsen5 through the action of climate change. As well as reducing emissions, improving water efficiency will help keep New Zealanders supplied with water.” “Currently many buildings are cold, damp and poorly ventilated which impacts on occupant health and wellbeing6. The indoor environmental quality (IEQ) of buildings is primarily related to how much energy is required to maintain suitable indoor conditions throughout the year ie the operational efficiency.”
