Are Smart Buildings the future for Indoor Air Quality?

I recently participated in the London Build Expo where Smart Buildings emerged as a recurring topic of discussion. Intrigued by this, I delved deeper into the subject, specifically exploring its application to air quality.

What is a Smart Building?

A smart building is a structure that utilizes advanced technology and interconnected systems to enhance its efficiency, performance, and overall functionality. These buildings leverage various sensors, devices, and automation systems to monitor, control, and optimize various aspects of the building's operations. The goal of a smart building is to create an environment that is more sustainable, comfortable, secure, and energy-efficient, while also providing improved occupant experiences.

The aim is to create more intelligent, resource-efficient, and liveable spaces, whilst encouraging the well-being and productivity of the building’s occupants.

What are the incentives for Smart Buildings?

As we strive to encourage individuals to return to their workplaces and revitalize the economy, it becomes imperative to establish appealing environments. Smart buildings offer an excellent means to achieve this goal.

The incentives for smart buildings encompass energy efficiency, long-term financial savings, environmental responsibility, occupant comfort and health, enhanced security and a competitive edge in the market. These factors contribute to the growing adoption of smart technologies in the construction and real estate sectors.

As a minimum, an environment is needed that provides good indoor air quality, promoting the health and well-being of the buildings occupants.

How can smart buildings be used to improve air quality?

I recently learnt from Steven Bartlett’s diary of a CEO podcast, that people appreciate being informed. Therefore, Air Quality Monitoring is a great way to keep people informed. Real-time monitoring allows for prompt detection of issues and enables automated responses. Other integrated technologies include:

• Ventilation control: Smart buildings can dynamically adjust ventilation rates based on occupancy levels and air quality measurements. Thus improving indoor air quality.

• HVAC System Optimization: Heating, ventilation, and air conditioning (HVAC) systems can include smart thermostats which can take into account occupancy and external environmental conditions to operate more efficiently and deliver better air circulation.

• Filtrations Systems: Smart buildings often incorporate advanced air filtration systems with smart filters capable of capturing a wide range of pollutants. These systems can be monitored and maintained more effectively through automation.

• Occupancy Monitoring: Smart sensors can detect the number of occupants in a space. This information can be used to adjust ventilation rates and air exchange rates based on the actual occupancy, preventing over-ventilation in unoccupied areas.

• Humidity Control: Maintaining optimal humidity is crucial for preventing mould growth and improving respiratory health.

The list goes on, and the more research and data that is captured, the better smart technology works.

Why businesses should care about their indoor air quality (IAQ)…

Indoor air quality (IAQ) refers to the quality of the air inside buildings, as it relates to the health and comfort of the occupants.

Air pollutants can originate from various sources, including combustion processes, cleaning products, building materials, and outdoor air.

Poor indoor air quality can lead to a range of health issues, including respiratory problems, allergies, headaches, fatigue, poor productivity, and more severe conditions in the long term. Therefore, efforts to monitor, maintain, and improve indoor air quality are crucial for creating healthy and comfortable indoor environments, whether in homes, offices, schools, or other buildings.

Proper ventilation ensures the exchange of indoor and outdoor air, reducing the concentration of pollutants and replenishing oxygen levels. In some cases, if the outdoor air is particularly poor, sealed facades and mechanical ventilation will be required to ensure good indoor air quality. BUT… mechanical ventilation is not always necessary; it can cause unnecessary costs, increase energy usage, and elevate the buildings carbon footprint. An air quality assessment can help to determine this requirement.

In the context of energy efficient buildings that are tightly sealed, addressing indoor air quality becomes even more imperative to strike a delicate balance between energy conservation and creating a healthy living and working environment. Thus, recognising and prioritising indoor air quality is fundamental for fostering healthier and more sustainable living and working spaces. Moreover, now winter is settling in, natural ventilation via opening windows becomes less frequent, and can impact the quality of indoor air quality.

How can we help?

Engaging with experts can offer valuable insights into the indoor air quality of your building, accompanied by suggestions for enhancing the overall indoor air environment. This is relevant whether you have concerns about your existing building or if you are in the process of designing a new building or refurbishing an existing one. Implementing measures at the outset, during the design stage, ensures that considerations for good air quality are integrated into the plans, guaranteeing a healthy indoor environment for future occupants. Maintaining favourable indoor air quality can positively impact the well-being and productivity of the building’s occupants. Exe Valley Environmental can help navigate you through the planning process and understanding the air quality consultancy services that may be necessary for your development. We will guide you through each stage, from early design and pre-planning advice, to supporting planning applications and discharging air quality conditions. If you’re unsure about the assessments your project might need in terms of air quality, drop me a call/message or a note via the contact form, for some non-committal advice.
