Start with the lease – or even before! The commercial lease governs the landlord-tenant relationship and can be a vital tool for enabling control and flexibility over occupant comfort and traditional approaches to controlling utility costs. To ensure you can pursue smart strategies for workplace comfort, make your priorities known early in lease negotiations. By stating your requirements for an energy-efficient, flexible workplace in an RFP or Letter of Intent, the landlord can work from the beginning to meet your needs. Further codifying your plans in the lease will ensure your ability to pursue your real estate strategy throughout the duration of your lease. Utilize daylight Leveraging natural light in your lighting design has dual benefits. First, it reduces your energy bill by decreasing your reliance on artificial light. Second, increased daylighting has been shown to have a positive impact on the sleep patterns and overall health of office workers, often leading to an increase in productivity. Ask your interior designer about implementing design strategies like exterior shades or light shelves, which can redirect sunlight deeper into your space. The explosion of light-emitting diode (LED) technology has also led to smart lighting systems that can react and adjust to natural daylight and occupancy of the space or even mimic circadian rhythms to further extend its benefits. Additionally, companies like View, Inc., and SageGlass offer dynamic windows that adjust to weather and operating conditions, helping to maximize occupant comfort and access to daylight. Optimize HVAC for comfort and fresh air Tenant control of HVAC equipment varies depending on building size and equipment configuration, but there are several strategies that tenants can pursue to optimize HVAC equipment and operations to provide a comfortable work environment and minimize energy use. First, where possible, specify high-efficiency roof-top units that meet or exceed the U.S. Department of Energy's technical specifications. Coordinate with your landlord to confirm that RTUs are right-sized for your space. Supplemental HVAC should be ENERGY STAR ® -certified. For a relatively small upfront cost premium, high-efficiency and certified equipment can reduce energy use by 5 to 20 percent while meeting your space-conditioning needs. Also, consider talking to a mechanical engineer about utilizing sensors and controls to deliver fresh air to the space. Lower levels of outside air negatively impact indoor air quality and worker productivity. 1 Research from Harvard University shows that doubling ventilation from 20 cubic feet per minute (cfm) to 40 cfm, per person, can lead to a 40 percent improvement in occupant cognition over a standard, built-to-code building while only costing approximately $40 per person per year. Implementing a thoughtful HVAC zoning strategy during build-out can also help to ensure that the HVAC system is meeting the localized heating and cooling needs within a space. 1 2 3 1. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4031400/ th E l E a DER DECEMBER 2017 17
