Corporate Social Responsibility (CSR) is becoming an integral part of today’s business model, driving companies to conduct business in ways that minimize their environmental, social, and economic impact through a variety of specified initiatives.

One initiative that is taking center stage is the move to day cleaning. Building owners and facility managers, who are looking to lower building operation costs, are moving their cleaning to daylight hours. With past day cleaning myths gone and overall stakeholder value increased, the trend to day cleaning is sure to accelerate, and Harvard will continue to lead the way.


Harvard has been day cleaning for over a decade, and understands the process extremely well. It involves much more than shifting cleaning from night to day hours. It involves a change in culture, equipment, and cleaning techniques.

Our transition planning is extensive and very well documented, to ensure all goes smoothly. We provide the expertise, tools, and information necessary to communicate the benefits of day cleaning to the building’s stakeholders.

In addition to our vast experience, we are a certified Healthy High Performance Cleaning (HHPC) Day Certified Contractor.* With our past experience and this certification, Harvard is fully prepared to assist you in the seamless transition from night to day cleaning.


A well-managed day cleaning program can produce energy savings ranging from 4% to 8%. Operational efficiencies and asset preservation, resulting from the reduction of after hours use of HVAC, elevators, and other mechanical equipment, improve as well. Valuable benefits are achieved with little to no capital investment on the part of the facility. 


Building occupants see the cleaners and through their interaction gain respect for the jobs they perform. Day time cleaning improves quality, since a well lit area makes dust, dirt, and streaks on windows easier to see and address. In addition, occupants are able to respond to emergencies more quickly and building security issues are improved because the facility can shut down faster, if needed.


In helping our clients calculate the potential energy savings of their facility, we utilize an energy estimation tool developed by building engineers and energy experts. The six factors used in calculating energy savings; let us calculate your savings for you.

1) Cost of electricity per kw/h

2) Type of lighting control system

3) Percent building occupied after 6:00 pm

4) Type(s) of lighting

5) Building automation

6) Net leasable square footage
