We help property owners reduce electricity waste through simple audits, energy-efficient renovation designs, and targeted renovation work. From building assessments, improvement recommendations, and projected savings calculations to the actual renovation execution, the entire process is handled through a streamlined and measurable workflow.

Rising Electricity Bills, Yet the House Stays Hot?

Many homeowners have tried their best to save on electricity. Air conditioners are turned off when not in use. Lights are replaced as needed. Chargers are unplugged. The use of electronic appliances is limited. Yet, the bills remain high. The problem is that energy waste often stems from more than just usage habits; the source may lie within the building itself. The roof absorbs too much heat. Ventilation is poor. Rooms lack natural airflow. Lighting is inefficient. The placement of openings does not support proper circulation. Consequently, air conditioners and fans have to work harder every day. Without realizing it, your home or shophouse continues to incur higher electricity costs than necessary.

Energy-Efficient Renovation: More Than Just Changing Light Bulbs

An energy-efficient renovation doesn’t necessarily mean purchasing a lot of expensive equipment. What matters most is identifying the areas causing the most energy waste and addressing them with targeted improvements. That is why our approach begins with an assessment of the building’s current condition. We then help formulate renovation recommendations that are realistic, tailored to your needs, and aligned with your budget. The goal is simple: to make the building more comfortable, cooler, and more energy-efficient.

Energy-Efficient Renovation Solutions for Surabaya and Surrounding Areas

Surabaya is known for its hot weather and high air conditioning usage, particularly in homes, shophouses, boarding houses, small offices, and commercial premises. If a building is poorly designed, external heat easily enters and becomes trapped indoors. Consequently, occupants feel uncomfortable, leading to heavier reliance on air conditioning. Through our energy-efficient renovation services, we help improve factors that influence thermal comfort and energy consumption—such as roofing, ceilings, ventilation, lighting, material selection, and even water usage efficiency.

What Can Be Improved?

Every property is unique, so renovation recommendations cannot be one-size-fits-all. However, in general, the areas that typically have the greatest impact on electricity bills and building comfort include:
  1. Overheating roofs and ceilings
  2. Suboptimal ventilation
  3. Poor air circulation
  4. Energy-inefficient lighting
  5. Rooms that rely too heavily on air conditioning
  6. Leaks or water wastage in the plumbing system
  7. Room layouts that trap heat
  8. Building materials that do not support thermal comfort
We will help identify the priority areas for improvement, ensuring the renovation is efficient and avoids unnecessary demolition.

Services You Receive

Initial Building Condition Audit

Our team conducts an initial assessment to understand the condition of your house, shophouse, boarding house, or property. The assessment may cover room conditions, heat sources, electricity usage, air conditioning usage patterns, lighting, and ventilation, as well as potential energy and water waste. This provides you with an overview of which areas require priority attention.

Energy-Efficient Renovation Recommendations

Following the initial audit, we formulate renovation recommendations tailored to the building’s specific conditions. These recommendations may include improving ventilation, optimizing openings, adding insulation, upgrading ceilings or roofing, installing energy-efficient lighting, selecting more suitable materials, and reconfiguring specific areas to enhance comfort and efficiency.

Estimated Savings and Budget Prioritization

We help estimate potential savings based on the building’s actual condition and planned improvements. This way, you not only know “what needs renovating” but also understand which measures will have the greatest impact on comfort and cost-efficiency. If the budget is limited, work can be prioritized and carried out in stages, starting with the most critical areas.

Renovation Work by the Technical Team

Once the plan is agreed upon, the renovation work can proceed, carried out by the technical team and experienced contractor partners. You do not need to go through the hassle of finding tradespeople, comparing materials, or managing the project from scratch. The process is designed to be more practical and streamlined, while remaining tailored to the building’s specific needs.

Renovation Design and Cost Estimates

We assist in preparing renovation concepts, defining the scope of work, and providing clear cost estimates. The goal is to enable property owners to make decisions with confidence, eliminating the guesswork regarding material requirements, labor costs, or unnecessary work.

If you feel your home has undergone frequent renovations yet remains hot, or if your electricity bills seem disproportionate to your usage, this service could be a more appropriate first step.

Why Energy Audit-Based Renovations?

Traditional renovations generally focus on appearance, room function, and construction. These are important, but they don’t necessarily address energy bills and thermal comfort. Energy audit-based renovations look at the building from a more holistic perspective. They don’t just look good, but also how it functions every day.
  • Is hot air entering your home?
  • Is air circulation good?
  • Is the lighting efficient?
  • Do you need air conditioning all the time?
  • Are there any electricity or water wastes that could be reduced?
With this approach, renovations become more strategic. They not only enhance the building’s appearance but also help reduce long-term operational costs.

Examples of Energy-Efficient Renovation Work

  • Improving ventilation and air circulation
  • Optimizing openings to maximize natural light and airflow
  • Upgrading roofs or ceilings to reduce heat gain
  • Using materials that enhance thermal comfort
  • Replacing lighting with energy-efficient systems
  • Reconfiguring spaces to reduce reliance on air conditioning
  • Improving water systems for greater efficiency
  • Recommending simple rainwater harvesting systems where feasible
  • Optimizing the layout of shophouses, boarding houses, or commercial spaces for greater comfort.
