    Hey Ben, great first video super informative. Look forward to many more. How I wish I could sleep at night breathing in constant filtered fresh air, without outside noises being a nuisance.
    Comfort and health and durability in design makes a home for today and tomorrow.

    Great info. Beautiful home. In Germany, in the early 1990s, we had those roller shades (called 'rolladen' in German) and we loved them. In the US, they don't appear to be available.

      Thanks for sharing! Roller shutters are common here on project homes but rarely seen on architectural homes. They make a lot of sense if they can be incorporated neatly.

    Thanks for sharing this - really appreciate your perspective on needing an AC in a passive house (it's hard to find material addressing this online). Interestingly, our energy consultant told us that if we didn't install an AC, they would assume that a future home owner would install a least efficient version.

    • @theleanarchitect
      @theleanarchitect  Рік тому +1

      Yes. We have done the maths and find that in our climate, it is more cost effective and practical to include air conditioning and have it powered by the solar PV , than create a building that is somewhat impervious to summer heat gain.

    Interesting design and explanations. Now you have been living there for a while, have you found that the acoustic ceilings gather dust like a fan grill tends to do? This may seem a daft question but as a builder who has also lived in two of my own builds this aspect of dust-gathering (& accessibility to clean grills etc) actually became quite a bugbear for me in my first build and is something I designed out on the second build.

    • @theleanarchitect
      @theleanarchitect  5 місяців тому +1

      We have not had any issues with dust in the ceiling. Dust levels are definitely lower than on a normal house being that the house spends more time sealed up and the HRV filters out airborne particles.

    Hello Mr. Ben, i like the design of the home and I agree on part of the adopted solutions. May i know what is the time shift of the roof? I mean how many hours of delay between the peak of the heat outside and the peak of the heat inside. Do you also have a figure about how much energy per square meter does your house consume in a year? Thanks for the reply and wish you a good day.

    • @theleanarchitect
      @theleanarchitect  Рік тому

      Hello, Great Questions:
      The roof has a phase shift of 6.9hrs.
      In terms of energy use for heating and cooling:
      There is 0kw/h/m2/a for winter as we have never needed heating. (well below the Passive House standard of 15kwh.
      In Summer we have some cooling but this almost negligible (0-5kwh/m2/a) It is completely offset by Solar PV.
      For reference there is a single 6kw split system for 200sqm treated floor area. This operates for less than 100hrs a year at less than 50% capacity.

      @@theleanarchitect thanks for your kind answer. Usually in Europe we tend to build with insulation in mind plus mass in order to fight both winter cold and summer heat. All insulation material work against cold, but not all work against the heat. I believe, with all due respect, that 6 hours phase shift for your climate is insufficient for a good passive house since it means that the roof will not be able to damp and delay the heat wave efficiently. Maybe you did it on purpose, since you have only a 300kWh yearly consumption, but in Italy, where I live, we normally aim for at least 14 hours phase shift, preferably 20-24 hours shift. Thanks again, and wish you a great day

    • @theleanarchitect
      @theleanarchitect  Рік тому +1

      There are few local difference to account for:
      1: We have good diurnal temp change day/night. Peak daytime heat at 2pm, but by 7pm there is typically a cool shift from the ocean breeze.
      2: Local construction materials and norms would make it prohibitively expensive to build with 12 + hours of phase shift in roof and walls. Better to install a small AC for hot spells and power this with SolarPV.
      Also worth noting that a 6kw ac system only draws about 1.5kw at normal operating speeds. Our AC rarely operates above 50% so assume 500-750w of draw (same as our hot water unit). AC power draw is irrelevant anyway because we easily generate 4kw of power from solar.

    Brilliant design! How far north of the average home build price does this much emphasis on passive design go?

    • @theleanarchitect
      @theleanarchitect  Рік тому +4

      Thankyou. Its hard to compare with "average'' because the average standard is so much lower in specification in a thousand different ways. If this exact same house was built, but without the features that make this a Passive House it would save maybe $50k. We believe our homes are exceptional value for money when you compare the functionality, performance, comfort and specification against a typical custom or architect designed home.

    How do the costs compare between timber build and brick built?

    • @theleanarchitect
      @theleanarchitect  3 місяці тому

      We don't build from brick so it it is hard to do a side by side comparison with a similar project. Construction to this standard does use more costly materials and it is more labour intensive to install membranes, insulation compared to just slapping up some brick and rendering it. At a guess I would say +20% more

    I don't understand, why is e.g. an *air condition* called _passive,_ an _overhang_ well measured on the sunny side *is passive,* shading the summer sunshine-but letting the whole winter sun in.
    An HVAC can be _net zero_ using solar energy-passive meant for us something else in high school. But nice house anyway

    • @leslielugosi
      @leslielugosi Рік тому

      @@theleanarchitect I guess he meant the term "passive house" should use more passive principles like shading and using the hot from the sun by orientations. AC usually not needed in Hungary where we live if the passive component are correct. A good passive house - in my mind - have a massive thermal mass inside so it can provide stable temperature. As this house is wood, walls can not preserve heat or cool.
      Do floors have this mass?
