Flatrock Passive: Taking a Tour

first_imgEditor’s Note: This is one of a series of blogs by David Goodyear describing the construction of his new home in Flatrock, Newfoundland, the first in the province built to the Passive House standard. The first installment of the GBA blog series was titled An Introduction to the Flatrock Passive House. For a list of Goodyear’s earlier blogs on this site, see the “Related Articles” sidebar below; you’ll find his complete blog here. During the past year I have spent a major portion of my life implementing details that would ultimately lead to perpetually lower energy bills. Based on our final blower door test (0.36 ach50) and thermal imaging (to be presented in a later blog), I am confident that we have achieved the efficiency I was aiming for. This being said, a house has to be more than just a set of plans and a bunch of numbers on paper. It needs to be livable. It should be a space that you enjoy and become part of as you grow.My father and I spent two months working on various projects in order to complete the interior of the house. We had lots of ideas and details that we wanted to achieve. We decided early on in the project that we wanted what I call a “modern traditional” look, so most finishes were chosen based on that premise. The one project I am ecstatic about is the staircase! It was my first time building one and it turned out great! RELATED ARTICLES Heat-Pump Clothes DryersChoosing an Energy-Efficient RefrigeratorGBA Encyclopedia: AppliancesChoosing an Energy-Efficient TelevisionAll About Washing MachinesGoing High-Tech With an Induction Cooktop Interior detailsThe kitchen was installed by Dream Kitchens NL. We worked one-on-one with Krista Gernat to lay out the kitchen. Krista provided us with options like dovetailed drawers, waste pullouts, etc. Simple, flat-panel painted doors and cabinets fit well with the modern traditional theme. I installed solid birch countertops. For a woodworker, wood is easily fixed if it becomes scratched or worn. Simply scraping, sanding and refinishing provides a new countertop without tearing out the old one. The contrast against the blue cabinets is really eye popping (see Image #2 below).The living room (Image #3 below) is a great space. A large window provides lots of light. The Walltherm stove is commanding and contrasts nicely with the white walls. Once again, we dressed the wall behind the stove with shiplapped boards.The upstairs turned out as we had envisioned it. The painted wood floors look great and were quite cost-effective. We glued and nailed the floor down but there are still a few squeaks here and there. This is to be expected from a wide board softwood floor. I laugh and tell people, “We planned it that way. It is meant to sound like an old house in a Newfoundland outport community!”The bedrooms are spacious and have lots of closet space. Our laundry room (Image #4 below) was big enough for lots of cabinetry. The space will be used for storing linens, towels, and other household items.The master bath (Image #5 below) has a single sink and lots of space for a makeup vanity. There is lots of space for storage in all the cabinetry. The dining room is bright and spacious. The staircase is exactly as I had envisioned. My father and uncle helped with the installation. Although it was the first staircase I ever completed, I have quite a bit of woodworking experience so I saw it as a challenge. The simple spindles and skirts and treads go well with our simple furniture and fit nicely with the modern traditional theme.We integrated a shelved pantry under the staircase which is accessible by a small door. I sheathed the wall under the stair skirt with shiplapped boards. We felt this treatment added to the theme and also broke up the expanse of white walls. We decided to go with white (“Chantilly Lace” from Benjamin Moore) throughout the house and I am glad we did. Even on the darkest of days, there is enough light bouncing around from the large south-facing windows that we rarely have to turn on any lighting.center_img A very quiet interiorWhat is the house like to live in? It’s actually quite different than a code-built house. It is quiet … very quiet! We hear very little from outside the house. We typically don’t hear wind unless it gusts to about 50 km/hr (31 mph). The triple-glazed windows are also more soundproof. This is good since the glazing area is fairly large compared to some homes.Because the house insulates sound from the outside so well, inside sounds become more noticeable. It’s important when choosing appliances to consider the sound ratings of your appliances, or your refrigerator compressor and dishwasher pump will make you crazy! With concrete floors, the sound inside the house does bounce around quite a bit. It has a bit of a “pingy” sound but furniture and objects in the living space do cut down on this quite a bit.We’ve never been more comfortable. This has a lot to do with the fact that the structure is mostly free of thermal bridging and therefore maintains a higher mean radiant temperature. Triple-glazed windows make the space more comfortable and should be the standard. You can actually sit on the wide window sills when it is -10°C (14°F) outside and still feel comfortable! You may notice from some of the pictures that there are no heaters installed under the windows. They’re not necessary. The interior pane of glass is within a couple degrees of room temperature and therefore they do not lead to discomfort issues and are mostly draft-free because of this.

We went with Samsung Energy Star appliances where we could. The refrigerator (model RH22H9010SR/AA) uses about 635 kWh per year. The induction range (model NE58K9560WS/AA) uses about 355 kWh/year. The dishwasher (model DW80M9960UG/AA) uses about 239 kWh.The clothes dryer is a Whirlpool heat-pump dryer (model WED7990FW). It has a bit of a hum from the compressor. It is louder than most dryers but it is very energy efficient (531 kWh/year). It takes about 30% longer to dry a load but you can turn the heat on high to get it done quicker. The appliance is more efficient working at lower temperatures, so waiting a little longer is no big deal given the energy savings. Saving energy when it’s coldIn Newfoundland spring is kind of like winter. It’s cold! (WeatherSpark has some good visual graphs illustrating the weather for our region). Typical average high temperatures in April are about 1°C (34°F). Averages lows are around -5° C (23°F). In other words it is still heating season!We moved into our house in March. The first energy reading was in April at 1,232 kWh. On May 10 the meter reading was 965 kWh. Keep in mind that I am heating two buildings: a house and a garage for a total area of about 3,400 square feet. The three-year average for my last code-built house was about 2,400 kWh for the same month. That’s a savings of about 60% in electricity usage. In that house we cooked with propane and heated the garage with propane. The yearly cost of propane was about $1,100. The energy bills totaled about $4,500 a year. The total area was around 3,100 square feet including the garage. This is proof enough that superinsulation, airtightness, and very little thermal bridging have a profound effect on energy efficiency.As I write this, we are now halfway through May. The weather has been uncharacteristically good. It has been sunny and average temperatures have been around 5°C (41°F).I have been monitoring the heating system. Each connection on the manifold has a flow meter to indicate if heat is required in a given zone. There has been little to no requirement for heat during the past two weeks. Based on this observation, I think we are at the balancing point where solar gains and internal gains (from using appliances, taking showers, etc.) are balanced against heat flowing out of the building from thermal losses and ventilation. What does this actually mean? It means that heating season is effectively shorter because the house is able to capture more heat passively.Summer is coming. I have lots of exterior work to complete before the end of September. Why September? Because it starts getting cold again! Make hay when the sun shines!last_img read more

Distrust roils Chainpura

first_imgA sordid combination of rumours, distrust and fear of the unknown played a role in the brutal assault on four Sikh men seeking alms from the residents of this dusty village in the Ajmer district one month ago. The villagers here accuse the ‘sewadars’ of a gurudwara of ‘hypnotising’ them while asking for cash and foodgrain.The matter came to light earlier this week when a 51-second video of the Sikh men being abused and thrashed went viral on social media. The victims of violence, who fled to their native place of Khairthal in Alwar district, have not returned to Nasirabad to seek action against the youths seen beating them mercilessly in the video.The incident was similar to a recent episode in Jharkhand where six persons were lynched on the suspicion that they were child lifters. Villagers at Chainpura, situated 10 km from Nasirabad and dominated by Rawat Rajputs, insist that the incident involving youths from the nearby Chat Sardarpura hamlet was the culmination of tension building up in the area since long. “These Sikh men were around for several days. They asking villagers to donate foodgrain and threatening people who refused to do so,” Ajay Rawat, who owns a wine shop in Pushkar, said on Friday.The rumours ranged from child trafficking and molestation of women to hypnotism, robbery and selling low quality rice. The minuscule Sikh minority in Nasirabad was unaware of the incident until the video was circulated on social media.last_img read more

Gambhir should be fit to bat today: Team manager

first_imgIndia opener Gautam Gambhir should be fit to bat on the final day of the first Test against England if required, team manager Anirudh Chowdhary declared at the end of the penultimate day’s play at Lord’s in London on Sunday.”It was an impact injury. We have got it x-rayed and there is no fracture, nothing of the sort. He is presently icing it and he should be good (to bat tomorrow),” stated Choudhary.Gambhir was hit on his left elbow by a full-blooded sweep shot by England’s centurion Matt Prior while fielding at forward short leg.He did not come out to open India’s second innings, giving the place to Rahul Dravid.There was some more good news for India concerning Sachin Tendulkar and the perceived slow over-rates of the Indian team which, if otherwise, could have resulted in a ban for skipper Mahendra Singh Dhoni ahead of the second Test at Trent Bridge.Tendulkar, apparently, is on his way to recovery from the viral infection that stopped him from fielding for 215 minutes during England’s second innings.He came out to field after tea and will be able to bat tomorrow either after 98 minutes or at the fall of the fifth wicket, whichever is earlier.The word on Zaheer Khan was ambiguous which in other words implies that the left-arm seamer could be struggling to recover from his hamstring strain for the second Test.- With PTI inputslast_img read more
