Indoor Environmental Quality: Acoustics and Indoor Air

  Indoor Environmental Quality: Acoustics and Indoor Air



Indoor environmental quality especially in acoustical and indoor air quality is a concept that affects an occupant's health and productivity in a space. Having poor qualities can lead to lots of negative outcomes such as specific health issues. 


    Indoor air quality is governed by standards like the ASHRAE which covers the minimum ventilation requirements of a space to make sure there is sufficient outdoor air intake. This is to help maintain a healthy IAQ, buildings must also implement environmental tobacco smoke control measures. This helps also to prevent smoke transfer in units that are multi-resident. Effective strategies are source control to eliminate pollutants, proper ventilation and filtration, managing occupants' activities that may harm or affect the quality, and regulating the maintenance needed on HVAC systems.  



    Acoustic comfort is also a huge part of IEQ, especially in specific environments like schools or workplaces. In these environments concentration and focus is needed to the space working well. This should address sound insulation between rooms and a control over background noise from things like the HVAC and external systems. There are many different solutions to help the needs of this such as sound-absorbing materials, zoning noisy activities away from spaces of quiet. 


    Poor air quality and acoustics can lead to respiratory problems, fatigue, headaches, and reduced productivity. It is so important to think of these things first from the moment the design process begins in order to create a cohesive space. 


COVID-19 

    The effects of COVID had some positive and negative effects on air quality itself. A positive being an increased awareness prompting more individuals to invest better into different ventilation, filtration systems, and air monitoring. This led to ventilation improvements like updated HVAC and portable air purifiers to reduce airborne transmission.  

However, it also increased indoor occupancy which meant they were inside longer with poor ventilation. This led to a higher exposure to pollutants. Another fault was the overuse of disinfections which in poor ventilated spaces led to an increased indoor chemical pollution.

    Anna,
    Excellent Blog post. I enjoyed reading your summaries of IAQ and acoustics. These areas are so important for us to address. You provided great images and diagrams. I liked how you mentioned specific health issues associated with both topics. 50/50 points

Structural Systems

 Structural Systems      Interior Designers contribute to the environment of the interior spaces; this includes space planning, materials and finishings, casework, and furnishings. There are many jobs and services that an interior designer takes on throughout a space. Project Management is a large one that handles the project budget, contracts, scheduling, and resources of a project. There are many others that play into the smoothness of a project design itself these include, project goals, data collection, existing conditions, conceptualization, selections and materiality, documentation, coordination, contract administration, and pre-design or post-design services. Each one of these plays a role into the project and how everything comes together throughout a design.      Interior Designers do not work directly with structure systems; however, they need to understand how they work within a space. The purpose of a structural system is to carry the loads...

 Ceilings  Week Seven Blog Post  Chapter 9 Ceilings      Ceiling come in many different forms and materials that a ceiling can take on, one being cathedral and sloped ceilings. Cathedral Ceilings has a slope it creates a spacious space that a flat ceiling does not create. They have issues with lighting options, and you have to consider heating and cooling for the space. Directly applied ceilings are attached to the structure of the building these are normally made out of plaster or wood. Today gypsum wall board can be used in replacement of plaster. This can all be called drywall, it can come in a synthetic or natural source.  Suspended Acoustical-panel Ceilings are normally installed in the commercial environment. It provides noise control in large spaces as well as allows for duct work like sprinklers and electrical to be above the visual line. There are also many manufactures that create ceiling systems that are recycled and sustainable.  ...

 Week One   Chapter One: A Holistic Approach to Building Design and Construction  There seems to be a major concentration and importance of sustainability from the perspective of an interior designer. There are core principles of sustainable design, which include Energy efficiency, water conservation, material selection and lifestyle analysis, indoor environmental quality, and resilience and adaptability. As there has been more pollution and environmental effects the way we design buildings has become central to the issues as hand.  There has been a new idea of the building design process called Building Information Modeling. It requires all stakeholders in the building to be involved earlier into the process. The BIM system helps to reduce errors and is also used to generate pricing, energy models, and other services. This process creates building that have been thought through and carefully designed. The LEED Green Building Rating Systems rely on an integrated team...
