This Old House | Net Zero From the Ground Up (S40 E2) | FULL EPISODE

today on this old house our boards have arrived here in Jamestown on Island and in simply a duo hours we’re gonna have ourselves a new foot and our activities room sits on an island or homeowners non-powered is agreed to give us a little tour what happened to all this plumbing here I’ve never seen anything like this before there’s already rock going on in that trunk so what are you learnt up here well a bit of a surprise it’s really the classic plumbers lament I see this primary root form we’re just gonna drag that forward so it’s even where this existing deck is definitely says mid-century modern money’s in the detail that is beautiful[ Music] are ya Kevin O’Connor and welcome back to this old house here in Jamestown Rhode Island where we are working on this little bungalow that was built in the 1920 s now our homeowners Don and Dana they are the architect and decorator for such projects and they have got some big projects the most difficult of the purpose of which is to construct the house Net Zero which means that they hope it can produce as much energy as the house expends and that is a tall task but before we can even get to any of that we have got some issues to deal with here on the exterior and our builder is Jeff Swain or good morning Jeff Kevin oh I I’m well good to see you so demo today demo today inside and outside all right what are we doing outside well outside we got a little bit of an issue we’ve got a fiber cement siding shingle okay very popular in the 30 s 40 s 50 s and a problem here is that the fiber and this is asbestos okay so we’ve got to be real cautious we got to take precautions to get this removed safely and disposed of properly so asbestos shingles we’ve are dealing with them before and if I recall correctly when they’re in this territory no problem at all it’s when we start to break them up and those fibers become airborne that we had to help the risk that’s correct so it’s the demo that we’re going to be concerned with certainly not original of the members of this house if you’re saying hurl the fort over like an overlay all right original was a white cedar shingle and this was overlaid at some degree all right so the people are here what is the protocol for demolition they’ve got to take precautions with their personal protective rig sure they’re going to be wearing see armour and respirators yep and we’ve apply poly down on the sand so that we can contain all of this and then you’ve actually got a cordon off the region here so that everyone is bides safe everybody knows what’s going on okay so we’re wetting the shingles down with a soap irrigate combine the soap adds to help penetrate and keep the asbestos particulate down when we remove the shingles so you can see the cedar shingles underneath you’re speaking of original to the house probably right yeah and what’s its optional protocol for jettison yeah well each suitcase is sealed and then sealed inside that barrel we positioned them aside and it’s all sent to a transfer station approved for asbestos removal delightful and in terms of time how long deprive the whole house do you think I think we should have it to be undertaken by today awesome all right we’re underway because good progress in progress[ Music] Tom hey Jeff how’d you make do good got the story stick for us I noticed the subfloor right here so we can measure for the height of our new footing right so I’ve got a fib attach now that we’re gonna cornerstone on the bottom of that subfloor Yeah right here and the addition is two steps down from the original floor so from the old-fashioned part of the house when you enter the additive you’re gonna steps down into a apartment two steps correct okay then we’ve got an 11 and 7/8 I joists that’s a storey organisation yep two slabs and then there’s the top of our new organization right now the difference here is we’re actually going to be using a precast groundwork which conveys the height of the wall is established at the factory we can adjust that elevation with the opening so we now have to know exact ID of the wall as ever but now we can dig down to our position grant a little more for a stone locate and adjust that so the priorities in the wall will end up exactly right let’s hope so all right let’s get digging all right[ Music][ Music][ Music][ Music][ Music] I’m surprised to see a ground Wow no kiddin look at that about eight inches or so yeah this is pact pretty good yeah looks like we’ll have no problem produce that cut right there yeah we don’t want this wall to fall in but if you look at the foundation look those positions right there those are old councils and they probably constructed the forms right on the jobsite spewed the concrete let’s drift them off and use them so the old-time fixes wearing roof saving a horse all right so let’s get an idea on how much more we have to get down here or yep we need to go woo another three paws to the bottom of the underside of the hoof all right all right let’s see how we’re doing there’s our fanny okay now these people that continue to dig out for the whole foundation now it’s interesting Kevin went to the factory which is about three hundred miles away to see these boards being cleared oh wow can’t wait to see that yeah it’s cool this factory is an effort of Pennsylvania which is just outside of Lancaster in three districts away from our job place and this is where our concrete organization walls are going to be formed up moved segregated and filled with ornaments Doug could see you can reach you so you are Director of Operation correct yes so when someone asks you why help a precast concrete wall what are you telling them I tell them we have the ability to take your blueprints and do a custom-built intend exactly as you like we have the ability to pour it inside a quality saw environment where we control the weather we don’t have the circumstances that are harmful to the quality on-site we don’t have all the trucks that are sitting and waiting so we can build everything perfect to spec each time and how long to install usually less than one day Wow install in a single date that’s correct so you’re given a speed in character that’s right all right well how about sacrificing us a tour let’s go here in our production facility we’re going to build about five or six foundations a daylight “were having” 60 total employees each organization takes about three hours to build so we’ll run transformations for about 16 hours and be building the working day long yeah one of the station segments that we use is EPS it’s an expanded polystyrene it comes in these big billets this is the kind of styrofoam cup material precisely same thing what we’re doing here is cutting stud separation the entire profile is programmed on the CNC machine and we apply an electric charge to the wires and it goes through and melts everything and sections it to the exact specification like a hot spear through butter right that’s exactly right every textile that we use that is EPS will be trimmed on this machine using up all the waste for the best part the tiny little bit that we do have will be ground up sent back to the manufacturer and they’ll use it again cool here’s a piece of ornament insulation that was just chipped on the CNC so the concrete goes into the cavity now and then you’ve got the insulation now on the outbound back that’s correct Ryan’s gonna take a piece of galvanized roars and he’s gonna Bend invoices up so that the separation can sit down on top of that yeah restraints it in place and it also carries the rebar that’s going to go in the stud right here is where we’re going to start with your foundation this is our forum this is your forum right now we’re spraying the forum down with a light-headed weight for moil this will keep the material from affixing when we’re ready to row the walls so we’re bringing a opening frame in now this is treated 2 by 8 framing we’re gonna determined it on the deck square it off and we’ll nail it down in place so it doesn’t move during the process windows made to the exact specifications of the customer the pattern will be set to the depth that they miss right now they’re dropping in the studs that we checked rendered earlier they’re going to be spaced 2 foot on hub we’re gonna leant header and footer insularity at the top in the bottom which will provide the 2 foot spacing we’re frame number 3 rebar and the header and the footer “theres been” two bits in each and then number 4 prohibit will be vertical in each stud now that the studs are still in rebars in what we’re gonna start doing is putting down the insulation everything that we’ve done so far is is kind of an opposite of what you’re used to seeing from the inside the foundation so we’re gonna put this part of isolation in first it’s poly I so it’s going to give us our six and a half per inch and it’s foil faced foil face for shell and inhale prevention next we’ll have four and a half inches of EPS this imparts it a combined our importance of 21 station 3 wow that is a nicely isolated wall so this is where we’re gonna mix our concrete we’re gonna mix a 5,000 psi concrete we have 100% button over the combination because we’re in a climate controlled environment so if you guys are 5000 psi what is it typically on a jobsite spewed on site sure normally on a jobsite you’re gonna learn anywhere from 25 to 3500 psi and the reason for that is they just they can’t control the conditions you may have five or six trucks out there you’re sitting you’re waiting to pour you’re lending water and things like that merely doesn’t have a control what is the five thousand get us five thousand allows us to guarantee these walls to be watertight nice so we’re pour the concrete right now what we have is we have a one in three-quarter inch face shell and then we have a full penetration ornament hole so we actually have a nine and a half inches of solid concrete at each ornament but that skin is just going to be your inch and three quarterss so that’s not a great deal of concrete I represent how much is that compared to a traditional pour we’re gonna use about a third of the concrete as a traditional rained wall now that is remarkable and so you can see the depth of the stud there so that entire thing gets fill up with concrete and then this right here is just four inches three-quarters that’s exactly right and of course the header and the footer is full depth concrete and the consignment will give through the stud into the soil all right so this wall has been moved its seat overnight we’ve divested it and it is ready to be hooked up and load it onto a trailer well your oil piece that thing really slipped right out of there no problem at all it’s coming out the path it’s supposed to all right and that’s weighing in at of the reasons why do you think that special board is probably 3,500 to 4,000 pounds yeah and we’ll get wise on the trailer and send the walls up to Jamestown awesome love to see it thank you Doug I’ll see you there our programme house sits on an island that is surrounded by Narragansett Bay now specific populations of Jamestown year-round is about 5,000 but that figure grows considerably when the warm weather arrives and all the sightseers show up for the summer while homeowner Don influences has lived here for quite a number of years and you’ve agreed to give us a tour Don which we revalue how long you’ve been coming to Jamestown we were one of those summers beings 18 years ago and eventually we fell in love with the place and decided to make a home now well it’s not alike I convey it is beautiful utterly I’ve always affection to be drawn up now on the island with the boys and scramble the stones the tidal pools the views it’s just a magical situate it’s got a little bit of record to know sure that Jamestown has been at the center of American maritime history from day one this structure right behind you is the original foot of the third lighthouse in the Americas 17:49 Revolutionary War and patently it’s gone but they leant a new one up gotta go back so that’s right so is there a chance that a regional like you can talk our style into that lighthouse I’ll identify what I can do let’s give it a try so this is the southern tip of small island developing if you look who it is there you can see the outline of Block Island beyond that is Long Island as you come around here that’s the beginning of Newport and then we’re looking north along the leading edge of Jamestown you hear hull Cove then precisely beyond to the port rather all and then way in the distance is Newport Harbor and as the crow flies how far to your mansion about four miles from our home which is a pretty good run[ Music] the history of Jamestown has countless assemblies some of a very early ones were all about farming the whole island was devoted to farming and you hear evidence of it everywhere in the stone walls and a good deal of “the farmers ” that still remain some of them are historic preservation and others are still working and as a farming world on an island they needed some channel to process what they grow so they improved this windmill in 1787 and it’s still here today oh cool yeah you can see the two millstones looks like one turns the other abides still the corn is ground and comes out here into this as the cornmeal yep was like the drive gibe is coming down from above from the sales the sales of the large-scale the large-hearted fins on the outside yes I think so and then this is the hopper where you dump the corn in beautiful that is very cool yeah so here we are right in the heart of Jamestown this is Jamestown harbor and in the distance you witness Newport and then up this rise right here is really the crown jewel of Jamestown which is Shore B Hill beautiful look at those residences huh yeah they’re beautiful at the beginning of this century the well-to-do chose this detail for self-evident intellects to build their summer sits and of these rooms my favorite is the black one with the pitch-black balance and the dark shingles I time desire the surprise the unexpectedness of that emblazon compounding right and did you get other inspiration from it for your house the porch lines you’ll is displayed when you look at them are more than a little bit similar to what we’re doing at our live beautiful this is east ferry this is the center of municipality the members of this house that we spoke over on coast B Hill were being built at the turn of the century but also there were inns all along here this condominium construct right here is was built in the 80 s and to recall that hotel that once stood on that corner and you guys can walk to town from the house yeah and we often do my son comes down with his fishing rod get out onto the wharves to fish stops for an ice-cream cone on his course back home it’s it’s wonderful it is wonderful I represent everything you just showed me is wonderful it’s there’s a lot to cherish we adore it our bodies have arrived here in Jamestown on Island this truck came the whole way from the factory in Pennsylvania and in just a pair hours we’re gonna have ourselves a new footing hey Jeff hey Tommy hey guys doing hey Kevin oh yeah how’s a factory all the factory was cool man they was a lot of space on the roof constituted them up poured I’m insulated it leads fast yeah it’s great well talk about fast I means that we are utilized these years ago on our oldest projection but it was a big crawlspace then we used it on the Kyle out projection which was a big addition and we also use it on the Ted Benson panelized how supposed to be me yeah I adore them because they go in quick they’re insulated and they’re strong freedom so what did you have to do to prep the hole for us Jeff well we had to pour a single face wall because the existing foundation is a crawlspace so they had a transfer that load down on the bottom we had to calculate the bottom accurately because patently these committees are coming pre-made a certain summit yeah so we stone the bottom we’ve got a sump pump disappearing get rid of the irrigate as we go and we’re pointed up ready to set all right well I know Adam Campbell from the companies here so I want to check in with him accompany what the process is all right hey Adam hi Kevin good to see you again good to see you so jeff has come the whole most of the way there what are you guys doing to finish it off what we do now is we’ll locate the area pins of the foundation and they’ll lay out the string text what the string wire is set they’ll come in now and they’ll start screening and compacting the stone so this is you guys trying to get it to time the excellent stature now that’s correct so that when the walls are finished everything’s square level at the flowerpot all right let’s get to it all right great and now that the first body is placed in the next thing we’re doing now is placing this ceiling so you’re running a pellet right down the angle there yes it’s a raincoat sealant so this is a urethane based sealant I know it’s also pretty strong yes it is it does have adhesive strength and it certainly is for waterproofing the wall so how many pendants you’re gonna run in that corner I’ll be going three necklaces the first one is called the connector bead yeah and that’s really the the central B that thwarts the water from coming through right and then he’ll place an intern exterior pellet formerly the other panel is located Isis and the panels then are placed together and bolted with a half inch bar oh yeah right you exclusively bolted into sit and that’s correct at the bottom of the wall and at the top great then we’re ready to come in yes it is all right I need to get out of the way okay[ Music][ Music] over the past year many of you have noticed that our friend Roger Cook has not been himself we have received endless enquiries with sorrow and concern for his health well you’ve been curious and you deserve written answers so let’s catch out all right Roger around here pal are you feeling better we got some medical problems going around that I’m trying to take care of yeah keep health you’re in good hands though right good pas to get some of the very best doctors in the world we’re out in this area so good we’re working on it so what’s the plan move forward you’re gonna step back a little step back a little I think it’s time to stop the ponderous lifting and leave it up to the team we’re gonna put in place you know the guys that work for me Fred Tom Jonathan we got Jenna whatta we got Mike coming in I mean we got a crew that can fill in right behind me and I do a lot of this from now yeah you do have a great team as you said and Fred and Tommy and Jen can really step up to the plate with your guidance and mark McCullough doing all the hard scape stuff I mean you’ve got your back handled yeah that’s good that’s good we’ve always had one another handled as a team right Roger I convened you for the first time on the first this old house you are familiar with direction back 40 years ago it’s hard to believe right now and it wasn’t long after that that you were realise segments that our audience would look at and learn about seeds and landscaping and over its first year you generated an amazing body of work which is still very valuable too well I think we’ve all done that as a crew and it really testifies when “youre watching” it it’s your passion too I symbolize anyone else like to get as dirty as I do we’ve been friends we’ve been brothers and weapons we’ve been through a lot of nonsense together as a group what you did is you imparted the backyard into the house to be able you know a chamber in the house and be part of the demonstrate an integrated part of it yeah it’s been great but like I said I’m not absolutely disappearing I’m still gonna watch you well it’s a family brother and you’re part of it and we’re gonna stick with you through the part thing yeah expressed appreciation for you got it well it is a family and when you are on the receiving intention of so much kindness from so many parties well it humbles all of us so from our family and all of us ROG Richard norm and Tommy we’re gonna discover all of you next time next time on this old house we can finally discover the appearance that the house is in now that the demo is complete this is what we perceived when we opened the walls this was still sizzling a week ago f-for sure we demystify the suitable scheming of an HVAC system and to make this house Net Zero we got to break some rules you can see a traditional wall here is 16 inches on centre today we’re gonna chassis a wall at 24 inches on hub so you are breaking with more than a century’s worth of convention that’s next time on this old house
