You Build What?

Often, when we are talking to people about what we do, there’s a pause and then, “You build what?” It’s easy to reply, “an energy efficient home” but it doesn’t really get at the heart of what building passive or super efficient means and we want everyone to know because we believe that building in this way is just one way to make an impact on our environment for the better!

Here are some details of home building we consider/ implement for a passive or super efficient home:

Conditioned Spaces: the size and density and where a home is geographically located is investigated to determine how much energy the heating/cooling/ventilation system would have to use per year. To determine this, we look at Peak Heating and Cooling loads. Peak heating is how much heat your system needs to put out on the coldest day of the year in the location of the home. Peak cooling then is the opposite. We build with dense packed cellulose insulation and do a rigorous amount of air sealing to keep the peak loads at a minimum. We want our homes to basically maintain a comfortable temperature of approx. 74F throughout the year which for the customer, results in lower energy bills.

Energy Sources: We want our homes to be significantly less consumptive than a standard home. To do this, we consider, how many people will live in the home and how the home will be used; what appliances will be in the home, what type of bulbs for lighting, the hot water heater and the Energy Recovery Ventilator Unit. We design the windows to provide solar gain in the winter when it’s needed and avoid window placement in areas where summer heat gain would be greatest. We evaluate the quality of everything making up the home because it’s these materials and fixtures that play a significant role in the energy performance of the home.

Air Tightness: By using the right materials and well developed building practices that prevent air and vapor from penetrating or leaking through the envelope (your homes shell) you can have a comfortable and healthy home. To do this, homes are blower door tested, which is an interesting and informative part of the build. The house, once the windows, doors, siding, roofing, and insulation are installed, is closed up and pressurized using a fan placed in a doorway. As the fan runs, the amount of air that escapes the home is measured, through software, and the output is generated in cubic feet per minute at 50 pascals of pressure per square foot. FUN FACT: Pascal: a pressure of one newton per square meter or in S.I.: one kilogram per meter per second squared.

COMPLICATED!

Lets just break that down a little: the number generated from the blower door is the number of times the air volume changes in a house over an hour at 50 pascals of pressure. PHIUS (The U.S. Chapter) requires homes to meet 0.06cfm50 per ft2 to be considered passive. The lower the number, the tighter the home! Some City and County Building departments will also have their own standard for air tightness as well. For example, in the City of Fort Collins a homes air tightness “shall not exceed 3.0 ACH50 (air changes/hour at 50Pascals of pressure) for either gas or electric heated homes” https://www.fcgov.com/building/files/cfc-sfd-air-tightness-testing-protocol-v4.2.pdf?1588951497 This is an important and incredibly useful tool in determining the energy efficiency of a home!

Whew! you’ve made it through that lengthy interpretation of what makes a passive home, passive. By building thoughtfully, we create homes that make an impact in human health, building health and environmental health.

Home Design Thoughts

As a new “normal” takes new form and globally we start to shift toward developing new standards and regulations for how we interact, shop, learn and live, it’s worth also considering the place of home design, and for that matter maybe even renovations.

Some ideas that come to mind, stream back to early home design others are new thoughts about how we might shift spaces within our own homes to take on these “new normal” practices.

1. Vestibules: these rooms are more commonly known as “mudrooms” but don’t really function as they had originally. Today they are the catch-all. The mudroom is the place to collect our shoes, seasonal layers, grocery bags, the things needed for kids athletic practices, the place to do laundry, etc. However, in ancient Greece, vestibules were the barrier between one’s home and the outside world. Bringing a true vestibule into home design could give a more private and secure location for deliveries, as well as a holding spot for those who would like to make sure that any deliveries can be cleaned or properly prepared before entering the main living space.

2. Kitchens: Today the kitchen is the meeting place. It’s the spot where dinner and homework get done; where lunch and zoom meetings are happening. We have, over time transformed kitchens from contained work centers into the  most popular gathering place of our homes. In the early 1900’s, when tile and stone became more popular, kitchens were designed with hygiene in mind. Obviously, there is great joy in gathering around food but as we think more toward how to not spread or how slow the spread of illness during social gatherings, having a kitchen that focuses on just the art of cooking and leaving dinning and living spaces as the social spots could be an option that reemerges.

3. Washstand: Is the first thing that comes to mind when reading this, that age old concept of a pitcher in a large bowl? Hand washing is one of the easiest ways to slow the spread of many pathogens, and having a small dedicated sink that reminds your household and guests to do that before continuing into the main area of a home could become a thing, especially as we continue to hear from health officials about the importance of hand washing to slow the spread and see local retail shops putting out their own hand sanitizer stations, that encourage patrons to stop and clean before proceeding into the store, out for use. Having a powder room near the entrance of the home was quite common as private bathrooms and personal hygiene became a popular thing in the 19th century. More commonly, we see powder rooms in a more central part of a home, occasionally next to the kitchen or in between living spaces, but designing one next to the entrance of the home is easy to do and helps remind people to wash up before continuing into the house.

4. Better Home Ventilation: Talk about the next up-and-coming home feature. Instead of bragging about that low flow shower head, or super efficient windows, ventilation systems are going to be all the rage. Why? The cleaner the air in your home is, the healthier not just the occupants but the whole house is. In all of our homes, the ventilation system is just as well thought out as the plumbing or electrical system. Bringing air in, pulling air out, designing around wet locations and areas where there is greater solar gain, being considerate of where air might need to be more regularly refreshed and when makes our homes function efficiently and sustainably!

 

These are of course just some ideas, a way of looking forward to home and interior design!

Unveiling

One of the most prominent features of our current project in Fort Collins, is the first level concrete walls. These walls are 11ft tall and except for the front entrance planter (seen in this video) are smooth faced; the planter is board formed. The walls were formed with snap ties and have a very modern look. As we continue to strip away the forms on the walls we will share more videos and photos of this feature!

We also plan to host periodic open houses throughout this project, giving anyone interested an opportunity to come meet us, check out our project and ask questions. We will post the days of these events here and on our Instagram account.

Summers End

Summer is quickly coming to an end. We are happy about the cooler weather, and how well our project in Loveland is progressing. We are looking forward to new projects moving along in their stages of planning and we look forward to hearing from you-when you’re ready to build your dream home.

Energy With A View

When we think of solar installations, we generally think of those big black panels that dot the roofs of homes, buildings and sometimes the roadside. But what about windows?

When Robert Clarke from Alpen HPP LLC (our window supplier), called us up and asked if we would be interested in meeting the VP Sales Rep from Solaria about a new BIPV  (Building-Integrative Photovoltaic) technology they were working on for residential homes, we said yes! Solaria has been talking with Alpen to produce highly efficient windows with a solar grid in them. Not only would you/potential customers be getting a high performance window, but also one that is going to generate energy for your home. The windows have already been installed in larger commercial buildings, one specifically in Japan, you can find the link to the article below. Currently their BIPV glass panels, used in conjunction with standard glass windows are taking the idea of being “green” and “sustainable” to a new level. The panels not only collect solar energy, they provide glare control, thermal performance and effective daylighting (Solaria).

The idea of combining solar windows on a home, while also getting the benefit of daylighting, thermal control and glare reduction desired in a window is exciting. The fact that these cells are unobtrusive to the view is a huge positive. We are looking forward to seeing  how Solaria and Alpen continue to work out the details of making these panels for residential installations.

Here’s Jason, holding up the sample pane Scott Hoover brought over (the image has been edited to show the outline of the cells better. Had this image not been manipulated, you the reader would have thought Jason was just standing there with his arm up for fun-not something he is particularly known for)

Summer Hustle

IMG_4693eThese three have been staying busy; unlike the tiny boss chilling in the wheelbarrow above.

Once framing and sheathing wrapped up, we quickly got to work on air/water/vapor sealing, and installing windows, doors, trim and siding.

The design of the homes exterior incorporates wood, stone and brick. The homeowner had two colors of wood that she stained, one very dark and one very light-you could say it’s black and and white in appearance, but up close there is a lot more color variations including tones of brown and green that help give the homes exterior a very rustic country look.

IMG_4691e

Here is a corner photo of the two stains side by side.

IMG_4670eIMG_4674e

As you can see, there is a lot of character and variation in the color of the siding depending on light and where a person is standing.

IMG_4700e

The white siding has also been used as an accent color under some windows. The Cupolas along the roofs ridge provide a bit more character along the gable.

IMG_20160616_094641

The rough plumbing and electrical have been completed and we are getting ready to start blowing insulation.

IMG_4667

Just look at that light switch box! We really appreciate the work both the plumbing and electrical contractors have done!IMG_4695e

Here is a photo of the tenting around the fire sprinklers. This is a mandatory step before insulation can be installed. What we are doing, is creating a barrier between the sprinkler line and the cellulose; which will help to prevent/minimize the chance of the line freezing. The netting seen above the line will also be tacked to the studs along the walls, and cellulose will be blown in and dense packed.

Sprouting Up

Aaahh, spring has arrived in Colorado…or at least it seems that way on a bi-weekly basis. One week sunny and hot, the next cold and wet.

As promised, in the previous post a look into how the framing has been going. We have brought on, J & D Builders from Greeley to help us out, and we are really enjoying working with them.

Looking out the Dinning room window, that tiny person was placed there for scale. The homeowners wanted big windows to really capture the view they have of the buttes and Horsetooth Rock from the North side of their home.

Looking out from the Kitchen into the rest of the first level. The “tiny person for scale” is standing in the Master Bedroom. The beam is situated over the Living Room.

IMG_4552

Here our scale model is standing under the beam and in front of her is the wash room and access to the garage. There are high ceilings throughout. The beams and columns for this project are Beetle Kill Pine, milled from The Forks Lumber Mill, whom we used for the Nederland Home.

IMG_4539

Here’s a look into the wall cavity. Soon we will be dense packing a whole semi load of cellulose into these cavities. One the ground is our vapor barrier. Just as on a roof, we must maintain a dry environment for the durability of our materials and the house as a whole.

Here’s a look at some amazing custom made brackets we had done for the home from Charles Lefkowitz at, Sculpture and Functional Metal Work. We will have an upcoming post with more photos of the brackets we are using.

There last two photos are of the column brackets, one from the side, and one from the front. These brackets are giving structural stability and a very modern and industrial look to the home.

 

That Brindle Look

Have you missed us? We’ve been busy but have some exciting update posts on the way to show just how things are progressing!

IMG_4398e

We’ve poured the concrete floor, and remaining walls on our Loveland site. We had some really strong winds Tuesday while we poured the walls, making for a lot of fun with the pump truck and hose. The following day was much calmer and hotter, and we started bright and early. The pour went smoothly, thanks in part to great team work from everyone and having a good pump operator…and a tiny person to keep everyone  in check!

The slab is going to be stained, and to give it a nice look, we’ve burnished it. The slab is also fitted for radiant floor heating.

Quinn (above) stripping forms where the outdoor fireplace will be. The concrete was poured in several locations with the board formed look, giving it a rustic and also modern feel. 

IMG_4418IMG_4420IMG_4426IMG_4424IMG_4440IMG_4452IMG_4456

Later in the afternoon, we began stripping the foundation forms and Jason started making saw cuts the following day.

IMG_4475IMG_4480

In the next post, we will be showing off how the framing is going. We’ve had a few stall days due to rain (and snow) but it’s moving along and we can’t wait to post about it!

The Day no one said Cheese.

Yesterday we poured 1000 sq. ft. of garage floor concrete. That might explain why no one said cheese, or “oh it’s you…again…” or “hey, hold my drink and watch this”… Everything went pretty well, except for the weather, which couldn’t decide if it was going to be sunny or cloudy with rain…or sunny with gusts of wind..or… And then there is the tale of two cement truck drivers-one who was on par with hand gestures and one who wasn’t… In the end, it all worked out and we got the work done!!IMG_4308IMG_4318IMG_4320IMG_4323IMG_4326IMG_4332IMG_4340

Strip, Backfill and Pour (repeat)

We’re still working on the foundation at our Loveland project. We’ve completed the footings, poured the walls and next week we start pouring the floors, beginning with the garage. Things are progressing quickly.

Last week we removed the forms on the larger back walls.IMG_4262IMG_4267IMG_4275

Did we forget to share photos of the wall being formed?? Of course we did!! So hey, why not add them now, because this wall really does deserve some attention…and they were already edited for a post but just like the missing pairs of socks after a run in the dryer…well…

Looking good, right!! We agree, it is.
