Green building (also known as green construction or sustainable building) refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building’s life-cycle: from siting to design, construction, operation, maintenance, renovation, and demolition. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort.
Pinetop’s objective in green building is to provide:
- ENERGY EFFICIENCY
This is accomplished through the use of high efficiency windows and insulation in the walls, ceiling, and floors. With the extreme climate change that the McCall area endures the type of insulation that is put into homes in this region is essential for energy efficiency. ENERGYSeal provides a seamless system design of insulation in Pinetop homes that is efficient, durable, sustainable, and healthy.
- MATERIAL EFFICIENCY & WASTE REDUCTION
This is accomplished through the use of BMC Select who provides Pinetop with wall panels along with trusses. BMC Select manufactures building components such as trusses and wall panels that support green building by reducing waste on the job site, using recycled materials, and improving the durability of the structural frame.
- SITE & STRUCTURE DESIGN EFFICIENCY
The foundation of any construction project is rooted in the concept and design stages. The concept stage, in fact, is one of the major steps in a project life cycle, as it has the largest impact on cost and performance. In designing environmentally optimal buildings, Pinetop’s objective is to minimize the total environmental impact associated with all life-cycle stages of the building project.

ENERGYSeal’s spray-applied systems create a seamless and airtight seal in every cavity regardless of complex framing and penetrations, this translates to a building that is quieter, healthier, more durable, comfortable and energy-efficient. Best of all, the reduced energy bills will pay for these benefits over and over, while reducing your building’s impact on the environment. And since there are no moving parts, the system will last a lifetime. ENERGYSeal’s hybrid insulation system is the best way to save money and reduce your building’s environmental footprint.
ICE DAMS AND ROOF DURABILITY
Every winter, building owners in McCall and Valley County file millions of dollars in insurance claims for roof leaks, property damage, and mold problems caused by ice damming. On average McCall receives 130″ of snowfall annually and the surrounding mountains are blanketed with over 300″. It is not uncommon for snow to accumulate on rooftops at depths of over 4 feet for months on end. When this rooftop snow is able to melt and refreeze to form ice dams the effects are often severe and costly for residential and commercial buildings. Over time Ice dams create roof leaks and sliding snow and ice can cause severe structural damage and threaten pedestrian safety. Building owners concerned with the effects of ice buildup spend time and money to chip away ice and snow from roofs creating dangers and liability for those removing the ice and pedestrians below. This annual snow and ice removal is not only dangerous and costly but also drastically shortens the life of a roof system. Most property damage and insurance claims that are caused by ice damming could have been avoided with proper insulation and roof system design and installation. Despite the common occurrences of ice damming there is a great deal of misunderstanding with regard to the causes of ice damming and its potential for personal injury and building damage.
Roofs should be maintenance free, time and money should not be spent worrying about and snow and ice removal. EnergySeal’s stringent installation techniques, high-performance products, and systems approach help create roofs systems that are durable, efficient, and nearly maintenance free.
R-value is the most common method of labeling the thermal performance of an insulation product. However, labeled R-value often does not reflect how well an insulation system will perform in the real world.
The R-value assigned to insulation products is measured under laboratory conditions that do not necessarily reflect real-world environmental conditions or installation quality. R-value measurements are derived from small, meticulously prepared laboratory samples that are tested in an airtight hot box without an air pressure differential across the test sample. In reality, building envelopes are constantly exposed to differential air pressures and temperature swings and insulation is often carelessly installed with numerous defects and bypasses.
Extremely air-permeable insulation systems, such as low-density fiberglass, can be especially prone to R-value degradation and additional heat loss/gain under adverse installation and climate conditions. Low-density fiberglass is a very porous material that relies on air pockets trapped between minute glass rods to reduce heat transfer. The ability for air to move freely through fiberglass is what makes it such an ideal material for a furnace filter. Unfortunately, when air moves around so does heat, and this property is the primary reason that low-density fiberglass performance can be impacted by convective loops under extreme temperatures and experience ‘wind washing’ outside of sealed laboratory testing chambers.
Floor heating, also called radiant floor heating, is a luxurious home feature and a popular trend in new housing, as well as in renovations that focus on clean, comfortable, design-led living.
Pros at a glance:(+) Energy Efficient Heating (+) Effortless to Run (+) More Space & Design Freedom (+) Works with all floor coverings (+) Safety and Comfort (+) Ease of Installation
Energy Efficient Heating
There are two types of radiant floor heating, electric and water-based systems. Both provide heating in a room from the floor up for consistent, efficient warmth. Warm water systems run hot water through pipes to create heat, whereas electric underfloor heating heats wiring beneath the floor to generate heat.
Traditional radiators need to be heated to a high temperature (between 149-167 degrees Fahrenheit / 65-75 degrees Celsius) in order to heat up a room effectively, whereas floor heating only needs to run at a temperature of 84 degrees Fahrenheit / 29 degrees Celsius or less, depending on the floor finish, in order to warm the room – thereby consuming less energy, and keeping your energy bills far lower.
Furthermore, radiators heat the air nearest them first, which is why rooms heated by radiators are prone to “cold spots”, meaning that the air feels cold in the middle of the room and very hot next to the radiators. This usually results in opening a window above the radiator to bring some fresh air in, and there we go again, letting all that energy paid to warm up the house escape out of the window. Radiant heat provides warmth from the floor up throughout the room without any cold spots or stuffiness in the area being heated.
Radiant heat provides an average saving of 15% on heating bills thanks to the efficient way it warms a home.
Effortless to Run
Once installed, underfloor heating needs virtually no maintenance and comes with a 30 Year Guarantee for total peace of mind. The Warmup heating controllers will ensure that your heating runs in the most efficient manner either automatically with a Smart WiFi Thermostat, or, if you wish, with a programmable thermostat that can be programmed to ensure the heating comes on at certain times, giving you the option to switch it off at night time.
More Space & Design Freedom
With radiant floor heating, you’re able to enjoy your whole room without radiators on the walls. Even the most modern radiators take up room on a wall, so imagine the design freedom you have with heated floors – you can decorate the walls as you wish, to really make a statement or simply achieve the minimalist look, whatever your style, and free from having to plan around radiators.
Works with all floor coverings
Underfloor heating gives you the freedom to design your home as you wish, making the most of all the wall and floor space. And you’re still free to choose the floor type that you want as floor heating works well with laminate, wood, tile, stone, carpet and more.
Safety and Comfort
When you have underfloor heating, you no longer need to worry about sharp edges or hot surfaces of radiators when younger family members are in the house. The heating system is safely tucked out of the way and won’t get too hot to the touch.
Radiant heat is also much better for the air quality in a room since it keeps the air fresh and oxygen-rich. On the other hand, high temperatures caused by radiators increase discomfort and reduce oxygen levels. The thermal circulation from air rising to the ceiling and then back gets all the dust going in circles which will not happen with a floor heating system.

Properly sealing of the building envelope is one of the most critical steps in constructing an energy-efficient home. Heating and cooling account for 50% to 70% of the total energy used in the average home, in which air leakage can contribute significantly to energy waste. Eliminating gaps in the building envelope reduces air leakage from areas such as wall joints.
Why Is An Air Barrier Important For Energy Efficiency?
Increased Comfort: A tighter building envelope reduces the amount of unconditioned air, drafts and moisture that can enter the home.
- Lower Utility Bills: Air leakage accounts for 25% to 40% of the energy used for heating and cooling, hampering the performance of other building systems such as insulation and HVAC. All building systems must perform well together to optimize the energy efficiency of a home.
- Improved Air Quality: A tighter building envelope reduces the infiltration of outdoor air containing pollutants, allergens, dust and moisture.
