1 00:00:00,080 --> 00:00:05,200 Speaker 1: Remember the insulation debate new h one insulation standards. The 2 00:00:05,400 --> 00:00:08,640 Speaker 1: Minister Chris Penk said, well, he didn't say, but he 3 00:00:08,800 --> 00:00:11,799 Speaker 1: quoted figures that it could be around forty to fifty 4 00:00:11,880 --> 00:00:15,400 Speaker 1: thousand dollars extra to meet the new standards per house 5 00:00:15,480 --> 00:00:18,840 Speaker 1: that's been built. He said that in July, and now 6 00:00:18,960 --> 00:00:21,880 Speaker 1: we've had some numbers done. It could cost as little 7 00:00:21,880 --> 00:00:25,119 Speaker 1: as two thousand, two hundred dollars to add to a 8 00:00:25,160 --> 00:00:28,800 Speaker 1: new three bedroom house. That's according to Quantity Surveying, your 9 00:00:28,880 --> 00:00:32,239 Speaker 1: QS who put the numbers together for ebos and New 10 00:00:32,320 --> 00:00:36,400 Speaker 1: Zealand Certified Builders and Nick Clements is YOURQS author. Nick, 11 00:00:36,440 --> 00:00:40,239 Speaker 1: Thanks for being with us this morning. Reilly, tell me 12 00:00:40,280 --> 00:00:43,640 Speaker 1: what is that two thousand, two hundred dollars estimate? What 13 00:00:43,800 --> 00:00:44,400 Speaker 1: is that for? 14 00:00:46,400 --> 00:00:51,800 Speaker 2: So that's the cost impact of meeting the new ah 15 00:00:51,800 --> 00:00:55,040 Speaker 2: Onne standard, which changed for the twenty twenty three last year. 16 00:00:55,960 --> 00:00:59,080 Speaker 1: Is this for the country wide? The average? How big 17 00:00:59,080 --> 00:00:59,960 Speaker 1: a home are we talking? 18 00:01:01,560 --> 00:01:04,039 Speaker 2: It was a two bedroom about one hundred and forty 19 00:01:04,080 --> 00:01:07,440 Speaker 2: square meter two story. Our three bedroom, two story one 20 00:01:07,520 --> 00:01:10,000 Speaker 2: hundred and forty square meter home based on the Orkhan 21 00:01:10,080 --> 00:01:12,320 Speaker 2: regions are sort of the upper half of the North. 22 00:01:12,160 --> 00:01:16,160 Speaker 1: Island, Okay and is this if you if you start 23 00:01:16,319 --> 00:01:18,720 Speaker 1: the work on the H one from design phase. 24 00:01:20,080 --> 00:01:23,920 Speaker 2: Yeah. So with H one, there's two ways of complying 25 00:01:23,959 --> 00:01:27,560 Speaker 2: with the standard. There's something called schedule method and then 26 00:01:27,600 --> 00:01:31,840 Speaker 2: the other option is calculation method. So how I describe 27 00:01:31,840 --> 00:01:35,399 Speaker 2: it to peoples, there's four different levers that a designer 28 00:01:35,480 --> 00:01:38,720 Speaker 2: can pull to enable them enable their design to meet 29 00:01:39,080 --> 00:01:41,560 Speaker 2: the standard. And those levers are the insulation and the 30 00:01:42,160 --> 00:01:45,000 Speaker 2: thermal performance of the floor, the walls, the windows, or 31 00:01:45,040 --> 00:01:48,560 Speaker 2: the ceiling, the roof. And if you do it by 32 00:01:48,560 --> 00:01:51,400 Speaker 2: schedule method, it basically pushes all of those lead leavers 33 00:01:51,560 --> 00:01:55,200 Speaker 2: to ten. So it basically ensures that the building complies 34 00:01:55,320 --> 00:01:58,600 Speaker 2: by making sure everything is up to a particular standard. 35 00:01:59,040 --> 00:02:01,760 Speaker 2: But what the calculation method allows a designer to do 36 00:02:02,160 --> 00:02:05,920 Speaker 2: is work out the film performance of that particular building, 37 00:02:05,960 --> 00:02:09,400 Speaker 2: so that design that a size floor area, wall area, 38 00:02:09,480 --> 00:02:11,760 Speaker 2: window area, and then they can pull each of those 39 00:02:11,840 --> 00:02:16,839 Speaker 2: levers individually to meet a design criteria so it meets 40 00:02:16,840 --> 00:02:20,120 Speaker 2: the performance required for the standard. And the thing is 41 00:02:20,120 --> 00:02:22,640 Speaker 2: that each of those levers has different costs. He'd click 42 00:02:22,680 --> 00:02:25,760 Speaker 2: on that lever costs a different amount of money. And 43 00:02:25,840 --> 00:02:27,720 Speaker 2: what we did with the exercise, where is basically looked 44 00:02:27,720 --> 00:02:29,760 Speaker 2: at each of those leavers. I looked at what was 45 00:02:29,840 --> 00:02:32,520 Speaker 2: the in that case, what was the minimum we could 46 00:02:32,520 --> 00:02:34,400 Speaker 2: do to meet the standard, and what was the cost 47 00:02:34,400 --> 00:02:37,040 Speaker 2: of each of those ex changes. And so you're able 48 00:02:37,080 --> 00:02:39,400 Speaker 2: to basically it's a bit more refined than what the 49 00:02:39,400 --> 00:02:42,200 Speaker 2: schedule method is. The schedule method puts everything basically the 50 00:02:42,200 --> 00:02:45,679 Speaker 2: most extensive option, really okay, whereas the calculation method you 51 00:02:45,720 --> 00:02:46,200 Speaker 2: can refine. 52 00:02:46,480 --> 00:02:48,320 Speaker 1: So you haven't obviously done a lot of work on this. 53 00:02:48,480 --> 00:02:51,560 Speaker 1: The minister hadn't. He was using numbers that were given 54 00:02:51,600 --> 00:02:54,480 Speaker 1: to him by a few random builders. Is there any 55 00:02:54,520 --> 00:02:57,360 Speaker 1: way it could cost forty to fifty thousand dollars for 56 00:02:57,400 --> 00:02:59,919 Speaker 1: a house, a three four bedroom house, as he's indica, 57 00:03:03,000 --> 00:03:03,720 Speaker 1: I don't think so. 58 00:03:03,840 --> 00:03:06,800 Speaker 2: No, No, it would seem it would seem pretty high. 59 00:03:07,240 --> 00:03:09,720 Speaker 1: Is there a difference? Can you are there? Is there 60 00:03:09,720 --> 00:03:12,040 Speaker 1: an allowance for a difference per region, because it's obviously 61 00:03:12,080 --> 00:03:14,680 Speaker 1: warmer up north than it is down south in these standards. 62 00:03:15,400 --> 00:03:18,160 Speaker 2: Yeah, in the in the code is what they call 63 00:03:18,280 --> 00:03:20,440 Speaker 2: us that our rating, which is the indication of the 64 00:03:20,480 --> 00:03:22,000 Speaker 2: film work performance. And so you've got to meet a 65 00:03:22,000 --> 00:03:24,480 Speaker 2: different a venue down south than you do in the 66 00:03:24,560 --> 00:03:26,600 Speaker 2: in the North Island, right, but it wouldn't and it 67 00:03:26,600 --> 00:03:28,760 Speaker 2: would be more extensive to meet that higher avalue because 68 00:03:28,760 --> 00:03:31,919 Speaker 2: you've got to have a higher performing component to get there. 69 00:03:32,040 --> 00:03:34,280 Speaker 2: But I don't think. I didn't actually do the exercise 70 00:03:34,320 --> 00:03:36,840 Speaker 2: on the other parts of the country, but I don't 71 00:03:36,840 --> 00:03:38,360 Speaker 2: believe it would make that much of a difference. 72 00:03:38,480 --> 00:03:40,400 Speaker 1: All right, thank you very much. A few times this morning. 73 00:03:40,440 --> 00:03:42,960 Speaker 1: Sounds like the Minister will be taking this one on board. 74 00:03:43,040 --> 00:03:46,800 Speaker 1: Nick Clements of us, the your QS, author of the numbers. 75 00:03:46,840 --> 00:03:49,240 Speaker 1: They've run the numbers on the new H one insulation 76 00:03:49,360 --> 00:03:51,880 Speaker 1: standards and found actually it's a fraction of what we 77 00:03:51,880 --> 00:03:53,200 Speaker 1: were led to believe. 78 00:03:53,960 --> 00:03:56,600 Speaker 2: For more from news talks, there'd be listen live on 79 00:03:56,680 --> 00:03:57,960 Speaker 2: air or online and 80 00:03:58,160 --> 00:04:00,440 Speaker 1: Keep our shows with you wherever you go with our 81 00:04:00,520 --> 00:04:02,240 Speaker 1: podcasts on iHeartRadio.
