<p> Initial thoughts may seem straightforward with a straightforward answer: durable housing is tough; its vertical and horizontal surfaces resist deterioration from weathering and use. It could be theorized that durable housing would possess three qualities. </p><p> Firmness - it is well built of solid materials. </p><p> Utility - it is useful and comfortable to its inhabitants over time. </p><p> Delight - it remains appealing from one era to another. </p><p> Durability is a key point to prevent the deterioration of structures, members, and building components over time and to maintain the safety, comfort, and health of its occupants. The question of durability, explicitly considers architecture over time. Different people will obviously appreciate and focus on different aspects of durability. Residents want to live in a pleasant and dignified place with a "good address". Neighbors want to look at something calm and reassuring, not odd or brutal. Maintenance people hope for buildings with predictable performance and the fewest surprises and problems. Planners and politicians worry about the quality of the cityscape, the social health of neighborhoods, and the cost to public budgets. </p><p> The important aspect of durability is that buildings that are considered comfortable and attractive are somehow more worthy of the trouble of maintenance and renewal than the buildings that are not comfortable or attractive. Therefore there is a high correlation that suggests that the physical, social, and aesthetic aspects of durability are definitely related. </p><p> This Issue will focus on durability in terms of the physical attributes, longevity, and performance based requirements. The need to build efficient, sustainable, durable and cost effective buildings for the housing sector has become more important than ever. The Building Envelope Performance heavily depends upon the various agents and environmental factors that affect it's function. Building science can be defined as the body of knowledge regarding heat, air and moisture flow in buildings resulting from these agents, and their affect on building materials and occupants. All definitions of service life and durability include references to the service environment, underscoring the key concept that durability is a function of both material and its environment, a point too often misunderstood by designers. </p><p> Longevity of housing: What is our expectation of how <a href="https://www.home247.co/%E0%B8%82%E0%B8%B2%E0%B8%A2%E0%B8%84%E0%B8%AD%E0%B8%99%E0%B9%82%E0%B8%94%E0%B8%A1%E0%B8%B7%E0%B8%AD%E0%B8%AA%E0%B8%AD%E0%B8%87-%E0%B8%9E%E0%B8%AB%E0%B8%A5%E0%B9%82%E0%B8%A2%E0%B8%98%E0%B8%B4%E0%B8%99/" alt="คอนโด พหลโยธิน">คอนโด พหลโยธิน</a></li> long houses should last? Some do-it-yourself folks build so that their "improvements" last until the house is sold to someone else. Bankers and lending institutions expect the structure to last 30 years from the time they initiate a mortgage on the structure. Serviceability could mark the end of its safe use. Catastrophic failure of a home's structure caused by wind or earthquake will mark the end of its safe use. Green building systems are on the rise and will have consumer recognition within the next few years. Consumers are becoming aware of the impact of their purchasing decisions. More attention is being paid to renewability, sustainability, and environmental impact of the materials and systems we advocate. There are many lessons from existing housing systems; given the massive housing stock in place, there is much information to gain by making a connection between existing housing systems and new housing. We should be able to make inferences from problems witnessed and to quantify the behavior and performance of existing structures. </p><p> The effect of the do-it-yourself market is far reaching. The large retail "big box" centers send the message to most homeowners that they can do most projects by themselves. Whether the job entails painting the house to building an addition, is often seen as week-end work. Professional support for such projects will almost always result in a better job. We need to be more cautious about what we tell people they can tackle. Real estate professionals often see that projects done by homeowners can lower the value of a house compared to not making any "improvement" at all. These types of improvements are also common in the commercial sector. </p>
