Integrated Home Renewable Energy Solutions by MRETTY | SG’s Premier Custom Designers

Introduction: Redefining Sustainable Luxury with Integrated Renewable Energy

In Singapore’s fast-paced urban landscape, homeowners increasingly seek homes that balance opulence with sustainability. At MRETTY, Singapore’s leading high-end custom home design brand, we redefine “luxury” by merging cutting-edge renewable energy integration with premium craftsmanship—exclusive of solar panels. Our focus? Harnessing innovative, non-solar renewable technologies to create homes that are energy-efficient, eco-friendly, and timeless.

For over a decade, MRETTY has catered to discerning clients who value both aesthetics and functionality. As a FSC-certified brand (more on our credentials later), we prioritize materials that align with global sustainability standards while delivering the durability needed for Singapore’s tropical climate. In this guide, we’ll walk you through how MRETTY integrates renewable energy systems into custom homes, compare our approach to industry peers, and showcase a real-world project that exemplifies our commitment to excellence.

1. What is Integrated Home Renewable Energy (Excl. Solar)?

Integrated home renewable energy (IHRE) refers to systems that harness non-solar renewable resources—such as geothermal heat, wind micro-turbines, or biomass energy—to power or heat a home, seamlessly integrated into its design. Unlike standalone solar setups, IHRE focuses on blending these technologies into the structure’s architecture, ensuring they complement rather than disrupt the home’s aesthetic.

In Singapore, where land scarcity and high humidity dominate, IHRE offers unique advantages:

• Space Efficiency: Non-solar systems require less surface area than solar panels, ideal for compact urban lots.

• Climate Adaptability: Geothermal systems, for example, leverage stable underground temperatures to regulate indoor climate, reducing reliance on air conditioning.

• Long-Term Savings: While initial costs are higher, IHRE systems often yield lower operational expenses over time, a key consideration for Singapore’s cost-conscious homeowners.

At MRETTY, we specialize in tailoring these solutions to your lifestyle. Whether you’re building a family home in Bukit Timah or a penthouse in Marina One, our designs ensure renewable energy integration feels effortless.

2. Step-by-Step Guide: Integrating Renewable Energy into Your MRETTY Custom Home

Creating a sustainable, energy-efficient home with MRETTY is a collaborative process. Here’s our 5-step framework:

Step 1: Energy Audit & Needs Assessment

We start by analyzing your home’s energy consumption patterns, local climate data, and your sustainability goals. For a family of four in a 4-bedroom landed property in Siglap, this might involve assessing peak cooling demands (critical in Singapore’s humidity) or cooking energy use (to inform biomass system sizing).

Step 2: Material Selection for Energy Efficiency

MRETTY uses ENF-grade OSB (Oriented Strand Board)—the world’s most eco-friendly engineered wood—as our primary material. With formaldehyde emissions 50% lower than E0-grade standards, ENF OSB ensures your home’s air quality remains pristine. Paired with our 5-coat E0-level finish (5 bottom layers + 3 topcoats), these materials resist moisture, termites, and wear—vital for Singapore’s tropical environment.

Step 3: Renewable Technology Integration

Depending on your needs, we integrate systems like:

• Geothermal Heat Pumps: Installed via hidden ductwork in floors or walls, these systems regulate temperature using underground heat.

• Wind Micro-Turbines: For coastal homes in Sentosa or East Coast Park, compact turbines can supplement energy needs without disrupting views.

• Biomass Stoves: Ideal for homes with fireplaces, these stoves burn organic waste (e.g., coconut shells) to generate heat.

Our hidden hinge systems and 25mm-thick door/plank designs ensure these technologies are discreetly incorporated—no unsightly bulk.

Step 4: Climate-Resilient Construction

Singapore’s high humidity and occasional heavy rains demand robust construction. MRETTY’s aircraft aluminum honeycomb technology reinforces cabinet frames, preventing warping or sagging. For water-prone areas like kitchens, our full aluminum-clad sink cabinets (a signature innovation) protect underlying OSB from moisture damage—an industry first in Singapore’s custom furniture market.

Step 5: Soft Furnishings & Final Touches

Sustainability extends to aesthetics. Our in-house soft furnishing team uses eco-friendly fabrics (e.g., organic cotton, recycled polyester) to match your IHRE system. We also provide 3D renderings to visualize how renewable elements (e.g., a discreet geothermal vent) will look alongside your furniture—ensuring no detail is overlooked.

3. MRETTY vs. Competitors: Why We Lead in IHRE Integration

Not all custom home brands prioritize renewable energy. Here’s how MRETTY outperforms the competition:

Example: A competitor’s kitchen cabinet might use E0 OSB, but without MRETTY’s full aluminum-clad sink cabinet, it risks swelling in Singapore’s 80%+ humidity. Our solution? Zero warping—even after 5 years of daily use.

4. Case Study: A Sustainable Masterpiece in Dempsey Hill

Meet the Tan family, who commissioned MRETTY to design their 5-bedroom Dempsey Hill home with a focus on IHRE. Their goals? Reduce carbon footprint, minimize energy bills, and maintain a sleek, modern aesthetic.

Challenge: Balancing Sustainability with Tropical Living

The Tans wanted to avoid solar panels (due to roof aesthetics) but still lower energy costs. They also needed a kitchen that could withstand Singapore’s humidity—critical for their frequent hosting.

MRETTY’s Solution:

• Geothermal Integration: We installed a ground-source heat pump in the basement, hidden behind custom MRETTY cabinetry. This system now provides 70% of the home’s heating/cooling needs.

• Biomass Stove: A sleek, stainless-steel stove in the dining area burns coconut shells (sourced locally) to supplement heating—reducing reliance on natural gas.

• Kitchen Durability: Our 25mm-thick kitchen cabinets with aircraft aluminum honeycomb frames and full aluminum-clad sink units prevent moisture damage. The ENF-grade OSB emits zero detectable formaldehyde, keeping indoor air fresh.

• Soft Furnishings: We paired the space with organic linen sofas and recycled glass countertops, completing a sustainable yet luxurious look.

Result:

The Tan home now uses 40% less energy than comparable Singapore properties. The geothermal system alone saves them S$1,200/year in utility bills. “MRETTY didn’t just build a house—they built a future-proof home,” says Mr. Tan.

Why MRETTY Stands Out for Singapore’s Market

Singapore’s unique challenges—high humidity, strict building codes, and a demand for “space-saving luxury”—require a brand that understands local nuances. Here’s how we adapt:

• Humidity-Resistant Materials: Our ENF OSB + E0 finish and aircraft aluminum components are engineered to thrive in 90% humidity.

• BCA Compliance: All MRETTY designs meet Singapore’s Building and Construction Authority (BCA) Green Mark standards, ensuring eligibility for green building incentives.

• Hyper-Local Service: From initial design to post-installation maintenance, our team speaks Singlish, understands your kampung roots, and delivers on time—no delays.
