For many building owners and property managers these days, there is a strong and growing interest in cleaner, energy efficient buildings. However, as many soon discover when beginning to investigate specific clean energy solutions, going green can be complex.
How do you know where to start? Is converting to solar energy a good move?
What if my building still has a lot of incandescent lights? Is it worth switching to LED lighting?
Should I be adding green space to my roof to help cut down on CO2?
And how about financing the various projects and understanding what types of tax incentives and rebates are available or if you even qualify for them?
These are all very good questions and important to answer before you begin your journey towards greater building efficiency. The reality here is that failing to have a well designed game plan on how to implement clean energy solutions can have a negative impact on your efforts.
To avoid this, we recommend a Clean Energy Roadmap.
What’s that, you ask? Well, it’s exactly what you suspect: a comprehensive strategy to evaluate a variety of potential clean energy investments that would reduce energy consumption and, if desired, enable a building to produce its own renewable energy. It can also be paired with innovative financing solutions to help pay for the various initiatives.
A Data Driven Process
A Clean Energy Roadmap (CER) analysis includes a list of tangible energy conservation measures (ECM’s), validated by data analysis, to support the decision making process. The list of potential clean energy solutions is rank-ordered according to overall economic value so that those projects with the most favorable economics are prioritized over those with, for example, longer cost payback periods.
The net effect is providing you as building owner/manager with more control over your energy spend.
The process itself involves a multi-step approach, as follows:
Specific steps within the process include the following:
A detailed audit of existing lighting in the building, capturing:
Wattage, lumen output and foot-candle readings
Physical condition of fixtures
Design solution for exterior lighting
Product specifications for LED solution, including ROI, NPV and environmental impact
Bid(s) for installing prescribed lighting solution
An ASHRAE-Level II Audit of the building, to include:
Review existing design drawings, as-builts, submittals, O&M manuals
Description of current mechanical equipment including condition, age, and life expectancy
Utility consumption & conditioned building data analysis (temp, humidity, light levels)
Facility visits (inspection of equipment/systems/envelope/controls)
Level 2 energy model using Trane Trace software
Meeting with maintenance personnel to discuss past maintenance and upgrades
Identify building code issues
List of recommended modifications to and/or replacement of existing HVAC equipment and operations to reduce energy consumption
Estimate of available utility rebates and other forms of subsidy to reduce project cost
An assessment of the building to determine if a solar photovoltaic system could be feasible, as well as the estimated cost and energy production potential
An evaluation of financing solutions that meet financial and operational goals including the feasibility of PACE
Any large scale effort should have a governing plan and clean energy initiatives are no different. A CER tells you which projects should be undertaken, in what order and why. It’s your playbook to deliver the energy efficiency goals you’ve set out to achieve.
