The Advantages of Replacing Windows

At a point in time, the windows in your commercial building are going to need to be replaced. When you do, there are some things that you need to think about before going out and buying them. Below are some things to consider before you make that big purchase:

  • Increases efficiency: When you install new windows in your commercial building, it improves the energy efficiency of your rental property. By selecting the right windows for your building, you can prevent energy loss and heat transfer. By replacing those old one pane windows or old technology two pane windows with more energy efficient ones, it can save you money over time.
  • New technology: There has been new technology since your windows were installed in your rentals. Window panes are better insulated now, plus there’s low-emissivity metallic coatings, new types of framing materials and tinting. All these improvements are geared towards durability and energy efficiency. You can also have security and safety features installed.
  • Increase value: By replacing windows, this enhances the value of your building. If you are planning on selling it, the new windows help with their streamlined functionality and efficiency. They will improve the appearance of the property too.
  • Areas prone to storms: If your property is in an area which is prone to high activity storms, you may require windows which are hurricane resistant. So, you may have to have ones which regulate the amount of pressure that they’re rated to withstand. Plus, they may have to be able to withstand wind speeds of a particular level.
  • Areas of high heat or extreme cold: If your property is in a high temperature zone, the windows may need to have a better solar heat gain coefficient. It will regulate how much sun is let in the in. If you live in a freezing climate, you may have to have double or triple paned models.
  • If you’re on a fault line: For the building in this area, you need to have the windows be safety glazed heat tempered, so they don’t shatter.

There are many reasons to replace windows in your commercial building.

Mixed Materials in New Builds

Since construction is done in certain ways over time, contractors making changes in how it’s done can be a drawn-out process. Contractors may be leery of anything new or untried. So most contractors when building, say an apartment building, often would rather select materials that they are comfortable with, know are reliable where they are sure that the pricing will stay affordable. However, there are new products made from mixed materials which may do the job even better. Below are some of these new products:

  • Bricks made using wool: These bricks are non-toxic and more sustainable. When making the bricks, a natural polymer which is removed from seaweed. Wool is added in too. The brick dries hard and is resistant to cold, wet climates.
  • Sustainable concrete: Recycled materials such as wood chips or crushed glass are added to the concrete which reduces the CO2 emissions associated with concrete production. This helps to reduce the carbon footprint.
  • Insulation from the paper: Paper based insulation is made from recycled cardboard and paper. It’s fire-retardant and resistant to insects because of the boric acid, borax and calcium carbonate mixed with it. It can be blown into anywhere insulation is needed.
  • Triple-glazed windows: These windows help prevent heat from escaping a building because of the triple layer of glass. Krypton is injected between each layer, plus low-emissivity coatings are added for further heat escape prevention. If the window frames as also insulated, this will add to the insulation factor.
  • Solar tiles: Most roofing tiles are made from concrete or clay and are used for protecting roofs from the elements. But, many companies are now taking advantage of the sun’s energy by using solar tiles. These tiles not only protect the building from the weather but can help generate power.

As you can see, new mixed materials can be used in construction to help with saving energy.

Replacing Windows to Save Money

slide2When the muti-family apartment building you own has cracks in the windows or has windows which don’t close properly, it can cost you money. Because apartments which are drafty and cold in the winter require more heating. Also bad windows can make apartments too hot in the summer because of poor insulation. Further, even if tenants pay their own utilities, the heat loss and heat gain will destroy your budgeted expense payments because of the extra heating and cooling required in the hallways and common areas. So rents go up and then you lose good tenants and can’t even attract new ones either because the apartments also look rundown.

So replacing your windows may be the best option. In order to determine which windows will work best for your building though you will need to understand the energy performance ratings on windows. This way you’ll be able to make an intelligent decision on windows based on the design of your building and the climate in your area. Further, after you make your decision, hire a reliable contractor to install them properly. So all this stated, here is some helpful information for you dealing with the above matter:

  • South facing windows: South facing windows should have a solar heat gain coefficient (SHGC) of at least 0.6 to maximize solar heat in the winter when it is cold. Windows should also have a U-factor of 0.35 or less so it reduces conductive heat transferred out in the winter and in during the summer. A VT or high visible transmittance is needed for good visible light transference too.
  • East, west, and north facing windows: It’s harder to control heat and light transfer through east and west facing windows because of the sun’s rising and setting. So these windows should be shaded or have a low SHGC. North facing windows gain little solar heat so their main use is for lighting
  • Cooler climate strategies: Strategies which are effective here are using north facing windows and shaded south facing windows for reducing cooling loads. Windows with a low SHGS are especially effective here. You are trying to keep heat in in other words.

When your making your selection for windows based on energy efficiency, first consider the windows’ ratings in relation to what is your climate and the design of your building. Also you need to select windows that have both low U-factor ratings and SHGS to get the most energy savings in a climate with both hot and cold seasons.

However; the best advice is to talk to a specialist at a building supply company when you are buying your windows.

Lighting Up the Outside

When an apartment building is undergoing construction, one of the main concerns should be about proper outdoor lighting. Because with proper lighting, the tenants of the building will feel and be safer, and the reputation of the building being a safe place to live will increase. Also without proper lighting, tenant turnover may increase because people feel unsafe on the grounds after dark.

outdoor-lightingBut is professionally installed outside lighting really that important as opposed to you doing it? Actually the answer is yes. Because experts will know how to do it right. Because the reason for exterior lighting in parking lots anyway is to make sure there aren’t any hidden dangers and dark spots where threatening people can hide in. The exterior lighting should be bright enough then at 100 feet for a person walking to see potential threats and be able to avoid them. Bright lighting helps to deter criminal activity because of identification risk on the part of the criminal. Criminals like easy targets in dark places and professional lighting experts know how to design the lighting.

Also, another important area is the perimeter of the apartment building and the entry way. So exterior lighting in common areas needs to be on a timer or photo-cell which is timed to be turned on when it’s dusk and then turn back off when it’s dawn.

Perimeter flood lights with motion detectors are another option for safety issues. The motion detector will only turn on the flood lights when a human body comes across its field of detection. That way, if someone is on the premises or just walking around, the lights will come on and anyone out walking will be able to see that person.

With some managers, the concern that too much lighting will disturb the tenants in their apartments may keep some portions of the complex dark. Some of these areas may be the passage area between buildings, the swimming pool area, the area where pets can be walked and the laundry rooms. By hiring professional contractors who work with these issues daily though, they can use lights which have special light pollution and glare technology which will solve these problems when installed. With these specific areas targeted, the tenants can feel safe as they walk back and forth in these areas.

There are some things which should be left to the professionals and exterior lighting done correctly is one of them.

It’s not easy to determine if your windows need to replaced but your multifamily contractor should be able to give you advice. Your contractor can explain what types of windows are best for your situation. Many older window styles are made with single pane glass which is not as energy efficient.  The windows feel cold in the winter and can frost on the inside. In some cases, the windows may break.

Dual pane windows can significantly lower your energy bills because well-fitting, dual pane windows will keep out the elements such as wind, heat, cold, rain and snow. New windows will pay for themselves in a very short amount of time.

How to Make Rentals More Energy Efficient

Energy efficiency is a popular modern concern. It’s important to multifamily property owners for a variety of reasons. First, many current laws encourage energy efficiency upgrades. Many power and water companies offer rebates and other financial incentives for installing energy efficient upgrades to homes. For multifamily construction property owners who are concerned about the environment, they can make a difference by investing in these types of technologies. Finally, it makes good financially in the long run. Water, heating and gas bills will be much lower which will make the multifamily property much more profitable.

Some low-efficiency systems can run as low as 65%. You will quickly realize your return on investment as modern gas or oil furnaces range from 80 to 98%. New gas or oil burners can run at efficiencies from 80% to 98%. This can significantly reduce your bills quickly. You may also receive rebates.

Your multifamily contractor will make additional recommendations for addressing energy concerns. Are your windows tightly fitted? Can you feel air coming through the sides of the windows? If so, it may be time to replace your windows. Your multifamily units can lose a lot of heat and cooling through windows that don’t fit properly. It may also be a good idea to invest in energy-rated window coverings. These can block cold air and keep rooms from overheating in the summer.

Other issues to consider are unit doors which can allow heat and cool air to escape. Are your buildings properly insulated? Solar energy is a big investment but can provide big payoffs. There are many big and small ways your can increase your buildings’ energy efficiency.

Tenant Pet Peeves

Your best tenants may move when their leases end if your property has too many frustrating problems. As a property owner, you need to be aware of common tenant frustrations and make sure your rental units are up-to-date and function properly. If tenants complain about problems, you should address them immediately. Next, you should check to see if these issues are limited to one unit or are widespread. If your units are all having similar issues, it’s time to call in a multi-family construction company to help bring your property up-to-date so you won’t lose tenants.

Plumbing problems affect the quality of their day-to-day lives so they will lose patience quickly. Make sure you work with a multi-family construction company that has significant experience with plumbing issues. They can advise you on how to approach plumbing issues. Your multi-family construction partner may recommend a variety of solutions such as upgrading water heaters, replacing plumbing lines and a variety of other solutions.

Tenants expect their homes to be warm in the winter and cool in the summer. You will get complaints quickly if your HVAC system doesn’t function properly. Tenants won’t renew leases if they are physically uncomfortable. Dealing with HVAC issues can be a significant project. You should work with a multi-family construction company that can thoroughly examine your HVAC system and make recommendations for improvement. Some upgrades may have energy and tax advantages if you switch to more energy-efficient equipment.

Energy Efficiency and Mutifamily Housing

Multifamily housing provides homes for over 40 million people around the country, and there is a huge potential for improvement in energy efficiency in the industry.    State and local governments are moving rapidly to adopt benchmarking and disclosure laws as a part of their efforts to make existing buildings more energy efficient and lower energy bills for local residents.  Six major cities (including Austin, Texas) and two states, have adopted disclosure and benchmarking laws for multifamily housing energy efficiency, totaling over 1.3 million housing units.  The goal is to introduce competency and competitiveness in the multifamily housing industry that previously, was not seen.  Most apartment buildings are 36 years old on average and were built prior to energy efficiency laws were in place.  CNT energy conducted a study in 2012 with the American Council for an Energy Efficient Economy (ACEEE), which shows that energy efficiency upgrades in multifamily housing could save building owners and residents up to $3.4 billion annually.  Where do most of the energy compliance problems exist?  What repairs need to be completed to ensure energy efficiency?

  • Air Ducts

The energy commission estimates that improper air duct installation is responsible for 20 to 40 percent of energy loss in residential buildings.  Animals, rodents, and age can also result in tears or rips in duct work.

  • Insulation

The standard width of insulation rolls is 16 inches.  When the space between the floor and beams is narrower, many subcontractors will simply stuff the insulation into the space without cutting it to fit insulationproperly.  When insulation is compressed, it reduces the R-Value, a measurement of its insulation capability.

  • Framing

The energy commission advocates energy efficient design and construction methods that reduce the amount of framing and studs, and increase the amount of insulation.  Generally speaking, the more framing that exists creates a greater chance of energy loss.  Air penetrating through leaks in walls and framing can cause particles from fiberglass insulation to become airborne, causing potential respiratory problems.  The potential for air leaks also increases and can be even greater in buildings with various ceiling heights.

  • Windows

Heat gain through windows is responsible for 50 percent of the cooling load in warmer climates.  Improperly installed windows are a major source of air and water intrusion from unconditioned spaces.  Besides energy loss, water seepage can cause mold and decay, resulting in extensive damage.

  •  Roofing

The heat from a roof makes an air conditioner work even harder to cool a space.  Leaks or gaps in tiles or shingles can create for leakage or water seepage that could result in structural damage and mold.

With energy costs on the rise by more than 20 percent, along with a greater focus on energy efficiency, multifamily housing can gain profitability by focusing on improvements and gain tenant loyalty.
