more efficient equipment for our space heat and hot water would certainly help to offset some of this deficit. Can we call it a Passive House?As more people gain awareness of Passive House, many projects claim to be similar to Passive House, using Passive House principals, almost Passive House, etc. during our record cold weather this winter (almost 3 weeks with lows dipping into the teens and cloudy snowy skies for much of it) the living room heater struggled a bit to raise the temperature very quickly when setback at night. this is one of the benefits of leasing a PV system. Certification generally involves a third-party review of the energy modeling, blower door testing to determine airtightness, and commissioning of the ventilation system.Here’s some data on the 18th Ave Residence (as calculated per PHPP):Euroclime Larch Windows and Doors w/ triple glazingWhile they may be designed with the best of intentions, most so called energy efficient homes (and buildings of all types) designed and built today make many of the same mistakes:The simplest, most reliable, and most effective approach to energy efficiency is to focus first on the building envelope. In Lyon, France, the east bank, often referred to as the left bank, of the river has undergone a transformation that has taken the former ports from a riverside car park, to a varied public space that will facilitate relaxation and socialising and encourage both city dwellers and wider Lyon residents to use sustainable transport options. At the centre of the development, the Terrasses de la Guillotière – a brand-new stepped open space created as part of this project – offers a distinctive city-centre setting with unique views over the river and the UNESCO world heritage site formed by Lyon’s historic centre.

Technically, a Passive House must be modeled using special software (either PHPP or WUFI Passive) and meet criteria for Annual Heat Demand, Annual Cooling Demand (or heating or cooling load), Annual Primary Energy Demand (i.e. Credit: IN SITU Architectes Paysagistes.Visualisations of The Lyon River Bank. We think they turned out quite well. You will receive a link to create a new password via email. The Lyon River Bank. PHPP assumes 4 occupants for a house of this size, when in reality there are only 2 of us (plus 1 dog and 2 cats) which should result in lower overall energy consumption. Info at insituarchitecture dot netreally this post should be titled: in addition to a few weeks ago a 4.32kW PV system was installed on the upper roof which is expected to help the house approach net zero energy use.we're also excited to present a handful of new photos completed by local architectural photographer jeremy bittermann.drop us a line if you have questions, want to learn more, or just to say something nice.We're excited to share some new photos of the Oceanside Beach House. with fewer occupants, there will be lower internal gains which presumably would increase slightly the heating demand and heat load. if we were to change our gas water heater to electric even without a change in energy consumption, our monthly utility cost would be even lower by eliminating the minimum gas charges.aside from reducing our CO2 emissions and our consistently tiny utility bills, we're staying extremely comfortable year round - warm in the winter while barely using our heating system, and cool in the summer without any air conditioning. In*Situ Architecture is an Architecture firm serving El Paso and the Chihuahuan Desert region of West Texas, New Mexico and Arizona. so the answer is unequivocally yes, it is definitely working.we just wrapped up our open house and it was very well attended. Because we both work from home much of the week with computers and other devices running all day, it could be assumed that while there are only 2 of us, our consumption includes both home and work and would therefore be higher. It's important to correctly identify this information to predict the effect of shading on the building. overall we are pleased with the system although it is definitely not sophisticated, super efficient, nor great looking.

The selection of windows and glass can be complicated and overwhelming, and selecting the wrong glass can have huge consequences. as an example, a small wood stove might produce about 20-30,000 btu/hr when running hot, far too much from a single point source in a passivhaus. because the house is so tight and well insulated, a number of rooms don't have any heating source yet remain perfectly comfortable including the pantry, 'breezeway', main floor bathroom, and upstairs walk in closet.

It’s important to understand the entire long term impact of sourcing and using a particular insulation product. in our climate mechanical cooling seems like an unnecessary and wasteful luxury, and we frankly did not want it at all. suitable for below grade / underslab / comes in different densities         blowing agent (currently used in US) has very high GWP and therefore should be avoided.
