Building Modernization
Commercial Buildings Are Never Truly Finished
Every commercial property reflects the era in which it was built.
Architectural styles change.
Tenant expectations evolve.
Technology advances.
Market conditions shift.
As a result, even successful properties eventually face pressure to adapt.
Building modernization helps commercial assets remain competitive, functional, and relevant within changing markets.
For some properties, modernization focuses on appearance. For others, the objective involves performance, leasing, customer experience, or long-term value.
Most projects ultimately pursue a combination of these goals.
What Is Building Modernization?
Building modernization involves upgrading commercial properties to better align with current market expectations and operational objectives.
Some projects focus on storefront systems.
Others prioritize facade improvements.
Certain initiatives include tenant improvements, energy upgrades, or exterior building renovations.
The scope varies widely depending on the age, condition, and goals of the property.
Common Modernization Projects
- Storefront upgrades
- Facade renovations
- Entrance improvements
- Building envelope enhancements
- Energy-efficiency upgrades
- Property repositioning initiatives
These investments help commercial assets remain competitive in evolving markets.
How commercial storefronts changed, decade by decade
Most buildings carry the glass of the era they were built or last renovated in. Step through the decades to see what your building likely has, what fails first and what a modernization usually changes.
The 1960s building: plate glass and single panes
Mid-century commercial buildings used large single panes of float glass in steel or early aluminum frames. Float glass made big, clear storefront lites affordable, and modern storefronts spread along main streets and new strip centers.
- What it looked like: wide single-pane lites, thin frames, manual doors with heavy hardware.
- What fails now: no thermal performance, glass that is not safety glazing, corroded steel frames and leaking putty glazing.
- Modernization move: replace with insulated safety glass in a thermally broken frame, keeping the original proportions if the building has historic value.
The 1980s retrofit: insulated glass and tinted facades
After the energy crises of the 1970s, insulated glass units and aluminum storefronts became standard. Federal safety glazing rules from 1977 meant tempered glass in doors. Bronze, gray and reflective tints were everywhere.
- What it looked like: bronze anodized frames, dark or mirrored glass, double-pane units.
- What fails now: 30 to 40 year old insulated units fog, seals and gaskets are worn out, and the dark glass makes spaces feel closed off.
- Modernization move: reglaze with clear low-E insulated units, re-gasket and reseal, and refinish or replace dated bronze frames.
The 2000s renovation: accessibility and low-E
The ADA (1990) reshaped entrances, and through the 1990s and 2000s states adopted the International Building Code. Low-E coatings and thermally broken frames became common, and automatic doors moved into everyday retail and offices.
- What it looked like: clear or lightly tinted low-E glass, clear anodized frames, accessible entrances and automatic operators.
- What fails now: seals reaching 20 to 25 years, worn door operators and closers, first-generation low-E that falls short of today’s energy codes.
- Modernization move: targeted repairs and hardware upgrades now, with replacement planned around a lease change or energy project.
Today’s modernization: performance, transparency and security
Current storefronts combine high-performance low-E, argon-filled insulated units, warm-edge spacers and thermally broken frames to meet energy codes, with larger, clearer glass that puts the business on display.
- What it looks like: big, clear lites, slim sightlines, black or custom finishes, frameless or narrow-stile entrances.
- Options: laminated security glass, bird-friendly glass where cities require it, electrochromic glass that tints on demand.
- Why owners do it: better tenants and rents, lower energy use, and a building that looks current from the street.
Modernization upgrades compared
Not every modernization means a new facade. Many owners phase upgrades over several years, starting with the changes tenants and customers notice most. Relative cost compares the options with each other.
| Upgrade | What it improves | Disruption | Relative cost |
|---|---|---|---|
| Clear low-E insulated glass | Comfort, energy, appearance | Low to medium | $$ |
| New entrance and hardware | First impression, accessibility, security | Low | $$ |
| Re-gasket and reseal | Leaks, drafts, longevity | Low | $ |
| Refinish or recolor frames | Appearance, brand | Low | $-$$ |
| Thermally broken storefront | Energy, condensation, code compliance | Medium to high | $$$ |
| Security glazing and locks | Break-ins, insurance, peace of mind | Low to medium | $$-$$$ |
| Full facade replacement | Everything at once, new look | High | $$$$ |

Markets Change Faster Than Buildings
Most commercial buildings remain in service for decades.
Meanwhile, customer expectations can change dramatically within just a few years.
Retail environments evolve.
Office requirements shift.
Tenant priorities advance.
Consumer behavior influences design.
Because buildings typically outlast market trends, modernization often becomes necessary to maintain relevance.
This reality affects retail centers, office buildings, mixed-use developments, hospitality properties, and institutional facilities alike.
First Impressions Matter
Visitors notice a property before entering it.
Customers evaluate appearance immediately.
Prospective tenants assess quality during tours.
Investors consider presentation when reviewing assets.
Consequently, exterior building upgrades frequently become a major part of modernization efforts.
Areas Often Targeted
Element | Modernization Objective |
Storefront systems | Improve visibility |
Building entrances | Strengthen perception |
Facades | Refresh appearance |
Architectural glazing | Enhance experience |
Exterior finishes | Improve presentation |
Public-facing areas | Increase engagement |
Visible improvements can significantly influence how a property is perceived.
Storefront Systems Often Lead The Process
Commercial storefronts play a central role in modernization projects.
Visibility affects customer engagement.
Transparency influences perception.
Natural light contributes to experience.
Because storefront systems are highly visible, upgrades often create immediate impact.
An updated storefront can help reposition an aging property. Likewise, facade improvements frequently support broader redevelopment objectives.
This connection explains why storefront modernization remains common across commercial real estate.
Tenant Expectations Drive Change
Businesses evaluate properties differently than previous generations.
Flexibility matters.
Building quality matters.
Customer experience matters.
Workplace environments matter.
As a result, ownership groups frequently invest in modernization projects designed to attract and retain tenants.
Common Tenant Priorities
- Modern appearance
- Natural light
- Updated storefronts
- Attractive public spaces
- Professional presentation
- High-quality environments
Properties that respond to these expectations often remain more competitive.
Building Performance Has Become Increasingly Important
Appearance is only one part of modernization.
Operational efficiency matters as well.
Energy performance influences costs.
Maintenance requirements affect budgets.
Building envelope performance impacts long-term ownership goals.
Because of these factors, modernization projects often focus on both aesthetics and functionality.
The strongest improvements frequently support multiple objectives at the same time.
Property Repositioning And Modernization Often Work Together
Some buildings require more than cosmetic updates.
Ownership groups may seek a completely new market position.
Retail centers can target higher-quality tenants.
Office properties may pursue premium occupancy.
Mixed-use developments often evolve alongside surrounding neighborhoods.
In these situations, modernization becomes part of a larger property repositioning strategy.
Exterior improvements frequently serve as visible indicators of that transformation.
Competitive Markets Reward Updated Properties
Commercial real estate is highly competitive.
New developments enter the market regularly.
Tenants have more choices.
Customers notice quality differences.
Investors compare assets constantly.
Therefore, modernization often helps existing properties remain relevant against newer competition.
Common Competitive Advantages
- Improved property image
- Stronger tenant attraction
- Better customer experience
- Enhanced visibility
- Greater leasing appeal
- Increased market relevance
These advantages can influence long-term performance.
Long-Term Value Depends On Adaptation
Commercial buildings rarely maintain value through inactivity.
Markets evolve.
Neighborhoods change.
Business needs continue advancing.
Consequently, successful ownership often requires ongoing investment.
Modernization helps properties adapt to those changes while protecting long-term competitiveness.
This perspective has become increasingly important as commercial assets face rising expectations from tenants, customers, and investors.
Key Benefits Of Building Modernization
Improved Property Image
Exterior upgrades help strengthen perception and create stronger first impressions.
Tenant Attraction
Modern environments often align more closely with current business expectations.
Enhanced Customer Experience
Updated storefronts and facades can improve engagement and comfort.
Better Building Performance
Operational improvements frequently support long-term ownership objectives.
Stronger Leasing Performance
Competitive properties often attract greater market interest.
Long-Term Asset Value
Modernization helps properties remain relevant as markets evolve.
Modernization Is About The Future
Commercial buildings tell a story.
Some reflect the past.
Others adapt to the present.
The strongest properties prepare for what comes next.
Building modernization supports that evolution.
Rather than allowing assets to become outdated, modernization helps ownership groups improve visibility, strengthen competitiveness, enhance tenant attraction, and support long-term value.
When property image, building performance, customer experience, and market relevance work together, modernization becomes more than a construction project.
It becomes a strategy for extending the life and performance of a commercial asset.
Building modernization: common questions
What does building modernization include?
Upgrades that bring an older building up to current expectations: new storefronts and entrances, energy-efficient glass, refreshed facades, accessibility and security improvements, and building system updates.
How do I know what era my storefront is from?
Single panes in steel or thin aluminum frames point to the 1950s and 1960s. Bronze frames with tinted or mirrored double-pane glass are typical of the 1970s and 1980s. Clear low-E glass and accessible automatic entrances point to the 1990s and later.
Do I have to meet current energy code when I modernize?
Usually when you replace a whole storefront or facade. Glass-only replacements and repairs are often treated differently. Your local building department decides.
Can a storefront be modernized without replacing it?
Often yes. Reglazing with low-E insulated units, re-gasketing, refinishing frames and upgrading the entrance can transform an older storefront at a fraction of replacement cost.
Can historic storefronts be modernized?
Yes, with care. Historic districts may limit changes to frame profiles and glass appearance, but insulated and laminated glass can often be used while keeping the original look.
How long does a facade modernization take?
On site, a few days to a few weeks depending on size, but design, approvals and fabrication usually add two to four months before work starts.
Where this fits in your storefront project
Every storefront moves through the same five stages: repair, deciding whether to repair or replace, upgrading, replacing and installing new. Pick the stage that matches where you are.
Repair
Fix what is broken. Broken glass, doors, frames, hardware, leaks and emergencies.
Repair vs Replace
Decide what makes sense. Damage, cost, building age, energy, safety and code.
Upgrade
Improve performance. Better glass, security, energy savings, access and appearance.
Replacement
Replace the whole system. Tear-out, full replacement, remodels and modernization.
Installation
Build something new. New construction, tenant build-outs and new storefronts.
Changing the opening or the layout?
If you are building new, enlarging openings or fitting out a new tenant space, the project is closer to a new installation. Plan the schedule and scope.
