7 tips for optimizing design of zero net energy buildings
19 Dec 2022
In an increasingly environmentally conscious
society, Zero Net Energy (ZNE) buildings has risen in popularity taking green
building design and construction to new heights.
The ZNE space has increased 700% since 2022
.Clearly ZNE is not a fad. ZNE is solving a real problem to help the
environment. So are you thinking of pursuing net zero? If so, here are some
tips to consider.
-
Plan for grid optimization. Solar and wind energy variability may only become more critical
in the future. As a result, demand flexibility can take a higher priority.
Having intelligent systems optimized for grid sensitivity can help. Reduce
the amount of energy that the ZNE will have to draw from the grid during
low solar intensity. With thermal energy storage, chillers can be
completely shut off as needed to maximize building load flexibility. Think
energy awareness and energy agility for better resiliency.
-
Evaluate potential for energy cost
savings. Energy pricing for commercial
building customers can be extremely complex and often misunderstood. ZNEs
relying on grid for back up generation can be subject to high demand
charges. Know the effect of the demand charges then design the building to
better manage them. Evaluate potential for renewable procurement and
distributed energy storage resources for a balanced energy management plan
that supports your building loads, geography, utility rates and local
legislation.
-
Address thermal loads first. To get to zero energy, controlling thermal loads is a must. Air-conditioning
is the biggest, easiest load to shift. Never use a battery to run a
compressor to instantaneously cool something. Instead, store the cooling
the night before and save the battery for needs that can’t be
stored. After all, just storing the cooling is much less expensive
and more efficient than the storing electrons to create the cooling.
-
Try a layered approach. A layered approach involving several technologies can help
reduce demand as needed. Start with storing thermal loads. Then use
batteries to power devices such as lights and computers and to smooth out
short fluctuations in energy consumption. Use combinations of fans,
outdoor air and window shading.
-
Take a future ready approach. Give yourself some room for actual energy usage which tends to
be higher than anticipated in the design or planning stage. Due to human
behavior and future peak demand for new electricity loads such as electric
vehicles, be prepared for future energy consumption. Consider room for
future expansion. Install new smart controls and smart connected devices.
Start programs to promote energy savings by tenants.
-
Gain meaningful insights. Like the old adage says, you can’t manage what you don’t
measure. Simple graphics can alert you if you’re at risk for going off
course. To begin, check that you are measuring the predetermined
performance metrics (energy consumption, carbon emissions, peak demand).
Use metering to measure the building activity and energy consumption. You
should be able to easily monitor and control energy usage. Use forecasting
services for notification of potential peak demand events. Utilities may
have coincident peak days so you’ll want to avoid heavy energy use on
those days. Monitor that the storage is dispatched and that all efforts
have been made to reduce peak demand. Finally, data visualization can show
an important story behind the system’s performance.
-
Rely on trusted partners. There are numerous start-ups and new technologies. Don’t be
sold a bill of goods. Full service providers with decades of experience
that can provide turnkey solutions can help save time and money and
eliminate a lot of the complicated decision making. Have a partner who can
provide the answers you need, detailed energy services, energy procurement
and intelligent systems design.
