  • How Insulation Will Help Reduce your Building's Energy Costs

    How Insulation Will Help Reduce your Building's Energy Costs

    If your energy bill is high, you are not alone. About 20% of the energy we use in the U.S. goes to power commercial buildings, and a survey from 2012 shows that by far the highest use is heating. If you add together heating, cooling, and ventilation, then about a third of your utility bill is going just to climate control.

    This means that a key element of building efficiency is to reduce the energy used to heat the building, and insulation is an important part of this. Too many building owners focus on easy fixes such as using LED lights and buying more energy-efficient equipment. While these are important, insulation is a neglected factor that can result in significant savings for both new builds and renovated buildings.

    The Benefits of Proper Insulation

    Proper insulation, which covers walls, ceilings and floors, including floors in the building, has several benefits:

    • It lowers heating and cooling costs substantially.
    • It increases comfort for those working in the building, thus improving morale. For residential buildings, it improves resident satisfaction.
    • If you have archives or other areas that need to be kept at a constant temperature, it makes it much easier.

    How Does Insulation Work?

    Insulation works by reducing air flow into and out of the building. This means that it helps keep the heat out in summer and in in winter. A lot of people mistakenly think insulation "keeps a building warmer," when what it does is slow heat transfer. In the summer, the heat can rush into your cooler building, causing the systems to work harder. In the winter, heat will escape through every crack.

    Insulation, in other words, reduces the amount your heating and cooling systems need to work to maintain the same stable temperature. It is rated by something called the R-value, which measures the ability to resist heat transfer. The higher the R-value, the more efficient the insulation, but you should also consider the size and the shape of the space being insulated.

    What Types of Insulation Are There?

    There are several types of insulation, and which you should use for your building depends on its construction. It also depends on whether you are doing a new build or, as is far more likely in New York, renovating an older building.

    1. Concrete blocks or forms. Concrete blocks are a great form of insulation when used in combination with foam beads, trapped air, or specialized cells. Concrete forms, which are more versatile, are hard to impossible to install in existing buildings, because of the seal that is required and the custom nature of the forms. For most New York building owners, concrete forms are not going to be an option. Blocks, however, can be installed during a major renovation.
    2. Blown and sprayed insulation. This is much easier to install post construction. The insulation is a foam, cellulose, or fiberglass material that is blown or sprayed into vulnerable spaces. It can be put into spaces that are oddly shaped or difficult to reach but can be expensive on larger buildings.
    3. Blanket insulation. Blanket insulation is generally used in single family homes but may be an option for smaller buildings. Most insulation blankets are fiberglass, although they can be plastic or mineral wool. This is inexpensive for small buildings. They do, however, need to be fitted properly.
    4. Rigid fiber insulation. This takes the form of rigid panels or boards which are cut to fit the space they are required in. This is a great option for between-floor insulation as it is also fire resistant and can reduce the risk of a fire spreading through the building. They also have an excellent R-value, between R-4 and R-6.5 per inch.

    What Should You Remember When Installing Insulation?

    There are a few things you should remember if installing or updating insulation in your building:

    1. Don't forget the floors. Insulating between floors slows heat flow through the building and helps reduce the loss of heat and cooling effects. This is particularly true when different tenants have the heat set at different levels. A tenant who prefers the heat higher directly below one who is keeping it at a lower level will experience heat loss up into the cooler office, and then will have to turn their heat higher.'
    2. Make sure that the ventilation system is effective. Insulation makes a building more airtight, which can then cause moisture to be trapped into the building.
    3. Air sealing is important. Make sure that there are no gaps around windows or exterior doors. Stairwell doors should also be sealed as stairwells tend to cause air flow through the building.

  • The Benefits of Incorporating Sustainable Building Strategies into Mixed-Use Designs

    The Benefits of Incorporating Sustainable Building Strategies into Mixed-Use Designs

    As our awareness of natural resource limitations continues to grow, the advantages of sustainable building strategies and their incorporation into mixed-use designs becomes increasingly important. Mixed use design fosters integration and density with two or more residential, commercial, cultural institutional, and/or industrial uses. Efficient building strategies are those that make highly productive use of natural resources and drive benefits for the city and its inhabitants. What are some of these advantages?  

    Efficient Use of Space

    Sustainable building design enhances efficiency in the use of energy, space and materials. For mixed use buildings, space efficiency is a key component in sustainable building strategies. The efficient use of space translates into saving energy and reducing waste over the lifecycle of a building.

    Environmental Impacts

    Sustainable building design optimizes energy performance and savings with the use of energy efficient equipment and utilizes design strategies to decrease reliance on heavy use power systems. This leads to a more efficient use of energy and reduces the impact on the environment. Mixed use buildings also promote walkability and help drive positive environmental impacts by reducing the carbon footprints in cities. With a greater variety of uses offered within a smaller footprint, people are more likely to explore on foot or via public transit versus exploring the area by cab or car.

    Health Benefits

    Smart growth strategies such as mixed-use development encourages pedestrian-friendly design. By building mixed use environments, this can help drive more active lifestyles, drive a greater sense of community and contribute to a greater sense of place. Sustainable building strategies also drive better environments for their inhabitants by maximizing natural light and providing increased air quality.

    Social Stimulation

    UCal Berkeley’s Professor of Urban Design Donald Appleyard’s lifetime of work pursued studies in the social and psychological effects of traffic and neighborhood layout as well as how to make cities and neighborhoods safe and livable. His research showed that the volume of traffic on a street affected the quality of life for residents in profound ways. People tended to rank their neighborhoods more favorably if they lived near transit corridors, sidewalks and activity. 

    Sustainability

    All these qualities of  mixed use landscapes add up to increased productivity, vitality, and variety in neighborhoods, with an increasing focus on driving sustainability. The sprawling suburban model that the advent of the automobile encouraged is simply no longer viable for much of the world (is this relevant?). Mixed use design considers the fact that the city is constantly in a state of flux and provides opportunities for innovation in sustainable building. By promoting health, economy, efficiency, productivity, sustainability, and the social interaction of its inhabitants, mixed use design provides  more dynamic city life.
