1
00:00:00,080 --> 00:00:02,040
Speaker 1: We've got movement into the construction sector to tell you

2
00:00:02,040 --> 00:00:05,920
Speaker 1: about this morning as well. Overall, our insulation requirements going

3
00:00:05,960 --> 00:00:07,920
Speaker 1: to change. What we're doing is a whole of house

4
00:00:07,960 --> 00:00:11,760
Speaker 1: approach and that allows more flexibility into potential saving it.

5
00:00:11,880 --> 00:00:14,040
Speaker 1: They say fifteen thousand dollars off a new build. So

6
00:00:14,240 --> 00:00:16,560
Speaker 1: Julian Laser is the chief executive of the Building Industry

7
00:00:16,600 --> 00:00:17,919
Speaker 1: Federation and he's with us.

8
00:00:18,000 --> 00:00:20,079
Speaker 2: Julian morning, Good morning, Mike.

9
00:00:20,320 --> 00:00:24,200
Speaker 1: The schedule method doesn't allow for design trade offs. I

10
00:00:24,239 --> 00:00:26,000
Speaker 1: read in the early hours of this morning. What does

11
00:00:26,040 --> 00:00:26,400
Speaker 1: that mean?

12
00:00:27,560 --> 00:00:29,720
Speaker 2: Well, look at the one size fits all. So basically

13
00:00:29,760 --> 00:00:32,600
Speaker 2: what that is, it's a straight jacket. It forces you

14
00:00:32,680 --> 00:00:35,400
Speaker 2: to use an exact amount of insulation depending on what

15
00:00:35,680 --> 00:00:39,159
Speaker 2: zone that we live in. But it means it's more

16
00:00:39,200 --> 00:00:41,960
Speaker 2: expensive and potentially over the top. So doing away with

17
00:00:42,040 --> 00:00:45,320
Speaker 2: it and relying on the calculation modeling methods means that

18
00:00:45,360 --> 00:00:48,479
Speaker 2: we're going to have a lot more flex so designers

19
00:00:48,479 --> 00:00:53,319
Speaker 2: can use a bigger range of materials, which ultimately will

20
00:00:53,320 --> 00:00:54,160
Speaker 2: bring costs down.

21
00:00:54,440 --> 00:00:57,000
Speaker 1: Okay, so if you do the right thing by the

22
00:00:57,080 --> 00:01:00,080
Speaker 1: end of it, you'll get there. As opposed to it

23
00:01:00,120 --> 00:01:02,640
Speaker 1: is super prescriptive currently, is what we're saying.

24
00:01:03,480 --> 00:01:06,400
Speaker 2: Yes, I mean the schedule method though, to be fair,

25
00:01:06,480 --> 00:01:09,039
Speaker 2: it's simpler to use. You know, there's a simple table,

26
00:01:09,120 --> 00:01:11,039
Speaker 2: so you and I could look at that and understand it.

27
00:01:12,760 --> 00:01:16,640
Speaker 2: MB could have adjusted the minimum our values and so

28
00:01:16,800 --> 00:01:18,679
Speaker 2: that the schedule method would have still come out with

29
00:01:18,720 --> 00:01:22,679
Speaker 2: the same outcome. This way, though, means that ultimately you

30
00:01:22,680 --> 00:01:25,000
Speaker 2: you probably do have to depend on a designer or

31
00:01:25,000 --> 00:01:28,600
Speaker 2: an expert to help you do the final calculations. But

32
00:01:29,200 --> 00:01:32,720
Speaker 2: there's a lot more flex and that's the key.

33
00:01:32,880 --> 00:01:35,399
Speaker 1: Does that explain the twelve months sector transition? Do we

34
00:01:35,440 --> 00:01:37,959
Speaker 1: need a twelve month transition? Is it because of that

35
00:01:38,000 --> 00:01:39,360
Speaker 1: complexity you've just outlined?

36
00:01:40,160 --> 00:01:42,880
Speaker 2: Yes, it is, And look, some of the industry wanted longer.

37
00:01:42,959 --> 00:01:45,640
Speaker 2: I think twelve months will be long enough just so

38
00:01:45,720 --> 00:01:51,360
Speaker 2: people can adjust themselves to the having to do the

39
00:01:51,400 --> 00:01:52,200
Speaker 2: slightly differently.

40
00:01:52,960 --> 00:01:56,680
Speaker 1: It's definitely enough time good And does the fifteen thousand

41
00:01:56,680 --> 00:01:58,720
Speaker 1: per house on average sound about right to you? Because

42
00:01:58,720 --> 00:01:59,960
Speaker 1: that's a decent chunk.

43
00:02:00,840 --> 00:02:04,080
Speaker 2: There's a decent chunk. Look, I think time will tell.

44
00:02:04,360 --> 00:02:08,160
Speaker 2: I think that the majority of residential dwellings is probably

45
00:02:08,160 --> 00:02:11,520
Speaker 2: going to be the cost difference around a little bit

46
00:02:11,520 --> 00:02:15,600
Speaker 2: more modestly to say four to five K, but potentially

47
00:02:15,639 --> 00:02:16,399
Speaker 2: up to fifteen.

48
00:02:16,720 --> 00:02:18,240
Speaker 1: Okay, good to talk to you. You have a good

49
00:02:18,280 --> 00:02:21,920
Speaker 1: weekend as well, Julian Lace four to five K versus fifteen.

50
00:02:21,960 --> 00:02:23,480
Speaker 1: Have to talk to Chris Pink next time I have

51
00:02:23,560 --> 00:02:26,239
Speaker 1: him on the program. You're inflating the old numbers, Christopher.

52
00:02:26,680 --> 00:02:29,600
Speaker 1: For more from the Mi Casking Breakfast, listen live to

53
00:02:29,680 --> 00:02:32,760
Speaker 1: news talks. It'd be from six am weekdays, or follow

54
00:02:32,800 --> 00:02:34,359
