This thermal imaging report documents issues found in a home inspection and provides recommendations. Several issues are highlighted, including missing insulation in bedrooms and kitchens allowing cold air to enter, plumbing leaks detected in basements, and improperly sealed ventilation ducts and doors allowing air exchange. The inspector recommends addressing issues like these by improving insulation, sealing air gaps, and monitoring problem areas.
Step 5 Pressure Balancing of The Seven Steps of Building a Synergy Home. Air that is supplied to a room needs a return pathway back to the air handler when the door is closed.
Home energy audits are needed to ensure that your home performs. Don't waste money on energy efficient upgrades until having an energy audit performed.
Combustion Safety - Step 7 of The Seven Steps of Building a Synergy Home. Failure to follow combustion safety guidelines can lead to Carbon Monoxide poisoning and death.

Airtight Construction is Step 1 of The Seven Steps of Building A Synergy Home. Airtight Construction is the foundation of energy efficient building. However, in absence of the other 6 Steps a home may experience major issues.

State of the Art Review of Unvented Sloped Wood-Framed Roofs in Cold ClimatesRDH Building Science
Typical residential house construction in North America has long had vented attics above living space with the insulation and air control layer at the ceiling plane of the living space. Except for documented wintertime condensation issues in cold climates, such vented attics generally perform quite well, provided that they are ventilated adequately and air leakage from the interior is prevented. However, architects and designers are moving away from empty attics by using the attic space as conditioned storage or bonus rooms, or by designing larger interior volumes with cathedral ceilings. The practical challenges of ventilating cathedralized attics and cathedral ceilings have been significant, both because of increased geometrical complexity and because of the number of penetrations typically required for services.
Spray foam has been used successfully in tens of thousands of unvented roof assemblies throughout North America but some concerns remain in the building industry that these assemblies are inferior to ventilated roof assemblies. The National Building Code of Canada, in particular, makes it difficult for designers to use unvented roof assemblies, even using designs that are approved in similar building codes in the United States and have been proven to be durable, high-performing options. Over the past decade, the authors have been directly involved with studies of both 0.5 pcf (8 kg/m3) open cell spray foam, and 2.0 pcf (32 kg/m3) closed cell spray foam in unvented roof assemblies in various climates with continuous monitoring of temperature and moisture conditions. This paper provides a literature review of research that has been conducted on wood-framed sloped unvented roof assemblies, but will focus on results from a field monitoring study of sloped unvented wood roofs in partnership with the University of Waterloo, as well as a field survey that opened roofs and removed samples from aged unvented roof assemblies.

In North America, the apparent thermal conductivity (and R-value) of building insulation materials is commonly reported at a mean temperature of 24°C (75°F) and practitioners typically assume thermal properties remain constant over the range of temperatures that are experienced in building applications. Researchers have long known and acknowledged the fact that the thermal properties of most building insulation materials change with temperature. There has been little more than academic reason to measure and report this effect. However, interest in temperature-dependent thermal performance has grown with the introduction of new materials, increasing concerns regarding energy performance, and the development of tools transient energy, thermal, and hygrothermal simulation software packages (e.g. Energy Plus, HEAT2, WUFI etc.) that have capacity to account for temperature-dependence.

Agenda
1. Understand typical ventilation practices for multi-unit residential buildings including corridor pressurization systems.
2. Understand performance issues associated with the ventilation of high-rise multi-unit residential buildings including the impacts of stack effect, wind, and airtightness.
3. Learn about how the theory of airflow relates well to what is
measured in-service, but that the well understood theory is not always taken into account in design.

Cara Pasang Ariston Water Heater electric 082122541663 atau pemanas air listrik merupakan alat pemanas air yang menggunakan energi listrik sebagai sumber energinya untuk dapat memenuhi kebutuhan mandi air panas keluarga Anda secara praktis. Sebenarnya, untuk pemasangan alat ini bisa dilakukan sendiri tanpa harus memakai jasa tukang. Dengan begitu kita dapat lebih menghemat biaya pengeluaran untuk membayar jasa tukang untuk memasang water heater listrik.
Berikut ini hal yang perlu diperhatikan untuk memasang water heater atau pemanas air listrik :
· Sebelum memasang pemanas air, Anda perlu menyiapkan instalasi pipa untuk jalur air panas dan jalur air dingin yang masuk ke dalam water heater. Pipa yang digunakan untuk saluran air panas pada pemanas air tentunya harus pipa khusus yang tahan terhadap panas tinggi seperti pipa dengan material polypropylene, serta material non-korosif yang tahan terhadap berbagai cairan kimia dan bebas dari sedimentasi (pengikisan).
· Kran mixing atau yang biasa kita kenal dengan kran panas dingin yang memiliki 2 saluran yaitu saluran air panas dan saluran air dingin yang nantinya akan digunakan untuk menyalurkan air dari water heater.
· Alat water heater listrik lebih baik dipasang minimal 1.5m dari lantai agar memudahkan Anda dalam pemasangan dan pengaturan pada water heater serta agar terhindar dari cipratan air mandi.

There are a possibility of 3 to 4 problems in one picture.
The bay window extrudes from the kitchen area and is outlined with the red arrow on the digital picture.
1. The plug on the wall is leaking air.
2. Bay window floor insulation is sagging and not touching floor sheathing rendering it ineffective.
3. There is a dryer exhaust venting underneath the bay window. It might not be properly sealed allowing cold air to enter floor
cavity.
4. Poor insulation at the rim joist area (left side of picture) allowing the cold to infiltrate the home and causing cold floors.
Recommend investigating under bay window and removing old insulation and look for gaps or voids and fill them as
necessary. Reinstall new insulation and secure it properly making sure it will keep in contact with the floor for a long period of
time. And also make sure proper air vapor barrier is in place.
