Indoor Air Quality Consulting Services

In today’s market, employers and landlords are taking a pro-active stance on indoor air quality (IAQ) issues. The effect of poor IAQ on employee moral and productivity can be detrimental to the employee-employer relationship, as well as the tenant-landlord relationships. In today’s competitive real estate and job market, providing a pleasant and safe working environment can mean the difference between profit and loss. LEED certified buildings also have Indoor Environmental Quality prerequisites that must be met to achieve certification.

PENTA’s IAQ team has surveyed over 20 million square feet of commercial space, as well as single and multi-family residential structures. Our team includes Indoor Environmental Professionals (IEP’s), Professional Engineers, and Biologists. Our team is experienced in various building uses from institutional to health care to general office space. PENTA’s objective is to understand the subject facility’s condition, evaluate the potential concerns, and develop a strategy to mitigate the concerns that will produce a cost-effective solution to fit the client’s needs.
