Transformation to Net Zero Energy
Tasks for Today
- Improve energy efficiency.
- Drive your energy use down, then drive it down further!
- Reducing your energy needs is much less expensive than providing renewable energy.
- Implement an Energy Management System (EnMS).
- Implement the Plan-Do-Check-Act cycle to sustain energy and cost savings in a best practice strategy for connecting staff behavior and energy demand.
- Use the 50001 Ready Navigator step-by-step guidance to achieve continuous energy improvement.
- Learn about renewable energy.
- Identify options for emission-free energy sources (on-site, off-site, partnerships).
- Invest wisely.
- Consider how all procurement and investments impact the Net Zero Energy goal.
- Prepare a basic action plan and start to implement it.
- Net Zero is a target today, but will be a requirement tomorrow.
- Consider implications for long range planning.
Basic Action Plan
1. Assess your performance.
Identify current requirements. What are the needs for building operations? -for occupant activities? The more detail you can provide, the better. Describe energy needs by type, floor, activity, time of day, etc.
Evaluate your efficiency. How well (efficiently) do you meet the needs? Not every building has separate meters for different spaces or activities, but even without specific measurements, some efficiencies will be obvious. Are lights on in unoccupied spaces? Does equipment go to "sleep" when not in use? Does the HVAC work "harder" at some times than others?
Develop an integrated team approach. Energy demand is affected by a range of building features and occupant activities; identify key team representatives for each.
2. Update and improve.
Do the simplest, least expensive projects first. Evaluate more expensive projects, as well as planned purchases and renovations, in terms of Net Zero Energy. Will the new/renovation effort reduce energy use? Will it facilitate conversion to renewable energy?
Efficient systems. As you reduce your energy requirements, your systems (e.g., HVAC, lighting) may no longer by optimally sized. They may be designed for a larger load; operating for lesser loads is usually inefficient. Stage improvements accordingly.
3. Evaluate renewable options.
After reducing your energy use, the balance under net zero targets will need to be obtained from zero emission sources.
- Renewable Energy Certificates (RECs).
- Energy districts and partnerships.
4. Continuously retune.
- Reassessing and continuing to improve are applicable throughout this Basic Action Plan.
- Optimize your operations to make the most of what you have.
- Meet regularly with your integrated team and keep talking about performance improvement.
- Your building may be able to produce more energy than it uses, helping others reach Net Zero (e.g. portfolio or partnership).
Implications for Long Range Planning
Under Net Zero Energy, energy requirements must be obtained from zero-emission sources. That means you will need renewable energy generation – either on-site or off-site. So, facility cost/benefit comparisons should consider the eventual expense and potential savings of renewable energy acquisition.
Facility repairs and renovations
Repair may solve an immediate problem, but upgrade or replacement may prove the better investment overall. Determining which upgrade or replacement is optimum may be different when evaluating a facility for Net Zero Energy. Perhaps one solution is more compatible with – or convertible to – a particular renewable energy system.
Incorporate Net Zero Energy targets into contracts. Consider Energy Savings Performance Contracts (ESPCs). Assess a building’s potential for renewable energy generation in property valuation. Identify and compare inherently efficient building characteristics, opportunities for on-site generation, and availability of renewable energy for purchase or trade.
Not all buildings will be able to generate the energy they need on their own sites. Many will need to explore some sort of creative partnering (e.g. districts, associations). Perhaps one partner has sufficient roof area for significant solar energy generation, and other partners invest in the installation of the photovoltaics.
