HVAC System Design & Installation for Shopping Center Tenancies

This presentation provides a comprehensive overview of HVAC system design and installation considerations for three different tenancies within a shopping center: a garment alteration shop (Looksmart Alterations), a nail salon (Diamond Nail), and a coffee shop (Espresso Pump). It addresses the unique air quality challenges posed by each business, such as volatile organic compounds (VOCs), chemical odors, and roasting smells, and proposes solutions based on ventilation, air conditioning, and heating systems. The presentation emphasizes compliance with Australian Standards (AS) and the Building Code of Australia (BCA), including specific extraction capacity requirements for fans in various areas. It also highlights the importance of sustainable and green design principles, such as using solar power and natural cooling methods. The presentation provides recommendations for maintaining healthy indoor air quality and mitigating potential health risks associated with poor ventilation in these retail environments. Desklib provides similar solved assignments and past papers for students.

Ventilation

Problem Statement
In Looksmart Alterations
Healthy Indoor Air Quality involves ventilation, temperature and airflow. Human Odours and
the smell of the air fresheners’ fragrances can be found in Shopping Malls like Looksmart
Alterations popularly known as Volatile Organic Compounds (Mendell, 1990). All these
smells and fragrances in LookSmart Alterations can lead to allergy and asthma. The owner of
the shopping Centre must adopt strategies like air conditioning, efficient heating and
ventilation.

Methods of Providing Ventilation
In Diamond Nail
In Diamond Nail, ventilation must be integrated with effective implementation of air-
conditioning system (Magrini et al., 2007).The nail care and waxing smell is hazardous and
can prove to be fatal for Diamond Nail Employees since nail care and waxing contains
harmful chemical substances. Addition of humidifiers to those systems can lead to sick
building syndrome. Installation of HVAC system in the air-conditioned houses can reduce the
chance of sick building syndrome.
In Espresso Pump
Coffee beans are roasted in Espresso Pump. The roasting smell can create respiratory
problems like asthma or emphysema. Diacetyl and 2,3-pentanedione are two added as
flavouring agents to coffee which often leads to lung disease. Installation of HVAC system in
the air-conditioned houses can reduce the chance of related respiratory diseases.
Slide 4
Performance Requirements
Performance Requirements for installing HVAC are based on AS and BCA standards-
 Fans configured in the washrooms must have an extraction capacity of 25 lt/s
 Fans in the kitchen must have extraction capacity of 25 lt/s
 Fans implemented in the toilets must have extraction capacity of 50 lt/s

 Fans implemented in laundries must have an extraction capacity of 20 lt/s
Slide 5
Installation and Maintenance Requirements
Installation and Configuration of HVAC systems must comply with the regulations of AS
1668.1-1998, AS 4508-1999 and AS 4254.2-2012
Slide 6
Sustainable and green design
Sustainable and green design can be maintained by using Solar Power HVAC Systems. A
sustainable environment can be obtained by the usage of Trombe wells as well. HVAC
Systems can be implemented by using water as a coolant (Zhang et al., 2011). The HVAC
Systems can be implemented by natural means. The building owners must keep their
buildings’ doors, and windows opened during summer as that will allow cool air to come in.
The building owners again keep their doors and windows opened to preserve heat inside. In
this way, a sustainable environment can be maintained in the building by natural methods.
