Insulation campaign 50,000 homes above target as it closes

235,000 homes have been insulated under the Government’s Warm up NZ: Heat smart programme, well above the original target of 188,500 set in 2009.

Energy & Resources Minister Simon Bridges said yesterday a strong insulation industry had been built as a result of the programme, and the benefits of better home insulation had become well known.

The Heat smart programme is drawing to its planned completion following the launch of the Energy Efficiency Conservation Authority’s targeted Warm up NZ: Healthy homes programme announced in this year’s Budget: “This new programme offers free ceiling & under-floor insulation for low-income households, particularly families with children & high health needs. It’s expected to insulate around 46,000 additional houses over the next 3 years.”

US company creates solar-energy tiles

Published 18 September 2009

Philadelphia-based SRS Energy launched a solar-energy roofing tile at the American Institute of Architects’ annual national convention in April and has begun limited distribution through a partnership with US Tile, the biggest manufacturer of clay roofing tiles in the US.


The Solé Power Tiles are dark blue, distinctly different from the red or clay colours of standard tiles, but SRS said they could be installed without compromising aesthetics.

Springwise, which produces a weekly web newsletter focusing on innovation, said the tiles were made from a high-performance polymer often used in car bumpers, and were lightweight, unbreakable & recyclable.


It said flexible solar technology by United Solar Ovonic was embedded inside each tile, allowing them to function independently of each other. Meanwhile, the performance of the system as a whole is monitored remotely by SRS Energy & US Tile. SRS Energy’s director of engineering, JD Albert, also developed the electronic ink technology used in Amazon Kindle & the Sony Reader.

Colliers Jardine manager cuts $400,000 from highrise energy bill

Fine-tuning heat and cooling systems did it

Colliers Jardine’s national manager of engineering & facilities management services, Val Moraes, has won an energy-wise award from the Energy Efficiency & Conservation Authority, mostly for chopping $400,000 from the annual energy bill at the National Bank Centre in Auckland.

Mr Moraes said he took a scientific and analytical approach to monitoring systems and fine-tuning, rather than driving improvement by major refurbishments or overhauls. About 75% of common-area energy consumption on highrises occurs through airconditioning systems, so Mr Moraes brought big savings through intensive management and calibration of heating and cooling plant.

“In highrise buildings there’s always a conflict between heating and cooling systems. Both are run simultaneously to maintain balance. We’ve found that if we reduced unnecessary heating, the load on the chilling plant, which is a significant energy guzzler, was automatically reduced.”

Striking a highly consistent temperature balance also significantly improved the comfort of occupiers and helped operationally with dramatically lower complaint levels.

The Government’s new energy strategy is due out in October. The smart energy management measures that have been put in place at the National Bank Centre will mean it is one of the very few buildings in New Zealand that will not require any major upgrading or modification to meet the strict new standards,” Mr Moraes said.

The ability to cut energy costs is important in terms of tenant perception, as tenants focus increasingly on total occupancy costs, making buildings with lower operating expenses more sought after. “In the current leasing market, which is highly competitive, a proactively managed building is a significantly more marketable product.”

The National Bank Centre is jointly owned by Kiwi Income Property Trust and Capital Properties Ltd.
