How They Pulled It Off: Making a Midcentury Home Sustainable for the Next Century

Deborah and Jason DeSalvo, a couple from Montclair, embarked on a multiyear project to construct an energy-efficient, environmentally friendly home in Hunterdon County. Their primary goal was to create a residence with a minimal carbon footprint, integrated holistically into its natural surroundings. They acquired 43 acres of farmland and, with a strong commitment to sustainable living, began an extensive research phase to determine the best building practices and materials. Their vision was a traditional-looking farmhouse that covertly incorporated advanced ecological features. The DeSalvos collaborated with architect Bill Kaufman of WESKetch Architecture and Construction. Their detailed list of requirements included generating their own energy through solar panels and a geothermal heating/cooling system. They insisted on locally sourced materials, preferably from the United States and manufactured close to their home, to reduce transportation impact. Furthermore, they demanded a toxic-free environment, specifying all-electric, EPA-rated appliances and avoiding gas or propane. Jason DeSalvo emphasized his unwillingness to compromise on these stringent environmental criteria throughout the design and construction process. Kaufman embraced the challenge, applying the 'small-house architectural theory'—not necessarily meaning small in size, but rather small in environmental footprint. Although their house is 4,000 square feet, the design prioritizes efficient space utilization, ensuring every room serves a daily purpose. The layout also incorporates features for aging in place, such as first-floor living and accessibility without barriers. Kaufman described the final design as having outward simplicity but inward complexity, resulting in an attractive, livable home where the sustainable elements are largely undetectable to occupants. Functionality and design were inextricably linked in Cold Brook Farm's construction. Seventy-two south-facing solar panels and a sophisticated seven-zone geothermal system enable the house to achieve net-zero energy status, producing all the energy required for the household annually. This surplus energy is also sufficient to charge two electric cars for 15,000 miles each per year. A tightly sealed insulation envelope protects against external temperature fluctuations, while deep eaves regulate sunlight penetration, allowing warmth in winter and blocking excessive heat in summer. Extensive southern-facing windows maximize natural light, reducing the need for artificial lighting during the day. Interior design, spearheaded by Anastasia Harrison of ADH & Co., also adhered to strict sustainability guidelines. All materials were sourced from American companies and local craftsmen, with a focus on sustainability. Walnut beams in the living room were crafted from trees harvested on the property, and materials like ceramic tile resembling brick and soapstone countertops were chosen for their natural properties, requiring no toxic sealants. All paints used were non-VOC. The DeSalvos repurposed existing furniture and meticulously researched new items to ensure they were free from noxious chemicals and petroleum products. Their commitment extended to avoiding shingles, specific tiles, gas lights, and generators. Beyond the house, the DeSalvos dedicated themselves to preserving and revitalizing their 43-acre land. They practice organic, regenerative farming, growing healthy food on 12.5 acres, including grain for flour. They preserved over 5 acres of wetland and 25 acres of natural woodland, reintroducing native plant species and removing invasive ones. Around the house, only edible plants or those beneficial to wildlife were used for landscaping. The DeSalvos acknowledged the higher initial cost, estimating a 30 percent premium over traditional construction, but highlighted the long-term environmental benefits and the anticipated 10-year payback period through reduced operating costs. #SustainableHome #NetZeroEnergy #GreenBuilding #HunterdonCounty #SolarPanels #GeothermalHeating #EcoFriendly #OrganicFarming #LocalSourcing

Updating an older home presents a unique opportunity to blend modern comforts with historical charm, preserving the character that new constructions cannot replicate. Interior designers, carpenters, architects, and real estate brokers emphasize the importance of thoughtful renovations that respect the home's past while enhancing its functionality and aesthetic appeal for contemporary living. The key lies in strategic updates that address modern needs without erasing the inherent historical details, materials, and stories that define these unique properties. One fundamental aspect of updating an older home is prioritizing the restoration of original features over outright replacement. Historic homes often boast distinctive elements such as crown moldings, corbels, unique tiles, original light fixtures, hardware, flooring, and built-in carpentry, along with fireplaces. These features contribute significantly to the home's character and are difficult to replicate authentically. Expert advice suggests salvaging and restoring these elements whenever possible. Even if extensive demolition is necessary, retaining and reincorporating salvaged pieces can help maintain the home's historical integrity and charm. This approach ensures that the unique identity of the older home is preserved for future generations. Another crucial upgrade involves installing energy-efficient windows. Older homes frequently suffer from inefficient or difficult-to-operate windows, leading to higher heating and cooling costs and reduced comfort. Replacing these with modern, energy-efficient options not only improves the home's insulation and environmental footprint but also enhances living comfort, all while maintaining the structural integrity of the property. When selecting new windows, it is advisable to choose styles that complement the architectural period of the home to ensure a cohesive look. To further honor the home's historical roots, selecting period-appropriate color schemes for paint and wallpaper is essential. Researching popular colors and patterns from the home's original era or architectural style can guide aesthetic decisions. This can involve consulting local colorists for historical accuracy, as demonstrated by the renovation of a Painted Lady home in San Francisco, where a colorist was employed to achieve an authentic facade. Such careful consideration of color helps in maintaining the historical ambiance while offering a refreshed look. Modernizing kitchens and bathrooms often involves replacing outdated appliances and fixtures that may be inefficient or visually unappealing. The goal is to integrate modern conveniences without compromising the home's historic aesthetics. This can be achieved by selecting appliances with finishes and hardware that harmonize with the original style. Similarly, updating cabinetry is vital for both functionality and visual appeal. Depending on their condition, existing cabinets can be refinished, or new ones can be installed. Two design approaches can be considered: either matching the new cabinetry with the home’s original style or introducing a contrasting, minimalist contemporary design that still complements the architectural context. Decorating an older home also benefits from incorporating historic and reclaimed decor. Vintage furniture, textiles, and knickknacks naturally fit into an older home's setting, creating a seamless and authentic feel. Researching the home's history and possibly sourcing old photographs can provide inspiration for suitable decor choices. Even newly purchased items like light fixtures or hardware can be chosen for their vintage flair to maintain consistency. Finally, addressing structural and safety issues is a paramount concern in older home renovations. This includes ensuring proper water infiltration management through the roof, gutters, downspouts, and foundation. Critical safety upgrades involve replacing old lead plumbing, safely removing asbestos, and resolving any electrical or mechanical problems. These foundational improvements are essential for the home's long-term safety, functionality, and habitability, safeguarding both the property and its occupants while paving the way for aesthetic enhancements. #HomeRenovation #HistoricHomes #InteriorDesign #HomeImprovement #PeriodAppropriateDecor #EnergyEfficiency #StructuralIntegrity #VintageStyle

The concept of the environmentally responsible home has evolved significantly over the past 80 years, shifting from early passive solar designs to more contemporary approaches like 'passivhaus' and inner-urban apartments. This evolution reflects the broader story of sustainability itself, marked by changing focuses and terminology. In post-WW2 Australia, architects, influenced by figures like Walter Bunning, aimed to create a better society through modernist suburban housing that integrated with the landscape and climate. This led to designs emphasizing climate response, such as courtyards oriented for sunlight and privacy. The 1950s saw the Experimental Building Station promoting these ideas through instructional booklets like 'Designing Houses for Australian Climates' and 'Sunlight and Shade in Australasia'. These efforts focused on 'moral encouragement' for passive solar homes, based on scientific principles. However, their impact on mainstream housing was limited, as mass production of detached houses prioritized speed and quantity over energy efficiency or environmental considerations for the rapidly growing population. The 1960s brought a surge in environmental awareness, inspiring designs that incorporated alternative technology. This period saw a revival of vernacular forms, experimental dome structures, and autonomous houses, all aimed at addressing ecological and energy concerns. Despite these audacious fringe projects, mainstream housing largely remained unaffected. The 1973 oil shock acted as a catalyst, shifting focus towards widespread energy efficiency. Research concentrated on water heating and thermal comfort, leading to recommendations for bulk insulation, double glazing, and internal thermal mass in floors and walls. These solutions, often derived from European or US contexts, primarily targeted heating needs and frequently overlooked the cooling requirements of Australia's hot climates. While individual highly efficient passive solar homes proliferated in literature, they were largely ignored by the conventional building industry. By the 1980s, efficient design began to be reframed as ecologically sustainable development (ESD). This broadened the scope to include water cycle issues such as collection, storage, use, and recycling. The long-term impact of buildings was assessed through life cycle assessment (LCA), which incorporated the embedded energy content of materials and other environmental factors alongside operational energy. Recognizing the limited impact of 'moral encouragement', governments in the 1990s initiated regulatory measures for responsible design. Minimum thermal performance standards were introduced through NatHERS in 1993, highlighting the need for Australian-specific solutions that address both radiant and convective conditions, requiring both cooling and warming strategies. This included external insulation (outsulation), shading, and ceiling thermal mass for passive diurnal cooling. In 2003, specific energy efficiency standards were integrated into the Building Code of Australia, followed by BASIX in 2004, which focused on energy, water, and thermal comfort. While initially more effective for detached houses, BASIX gradually improved its applicability to apartments. Measures like rainwater tanks, stormwater management, and on-site detention became standard. Digital modelling advanced throughout the 2000s, leading to calculations that promoted internal environmental quality (IEQ), encompassing thermal efficiency, natural and artificial lighting, and natural and mechanical ventilation. The German 'passivhaus' concept emerged as a benchmark for extreme energy efficiency, advocating for super-sealed homes with highly controlled fresh air to minimize heating and cooling requirements. However, its application in Australia proved controversial due to its origins in sub-zero European climates, with many arguing that traditional passive design, suitable for Australia's temperate conditions and occupant habits of opening windows, is more appropriate. Since the early 2000s, the widespread availability of affordable and efficient photovoltaic panels (PVs) has enabled homes and apartments to generate electricity, making them carbon neutral, net-zero, or even carbon positive. The definition of environmental performance expanded beyond the building itself to include the embodied and operational impacts of transport and infrastructure. This led to planning considerations regarding dwelling density and location to minimize a home's overall carbon footprint. The challenge became finding the optimal 'Goldilocks' density: too low, and transport costs outweigh building efficiency; too high, and energy demands for services like basement ventilation and air conditioning become problematic. Ultimately, the most sustainable solution identified is a passive-based, well-designed cluster of 'low and close' dwellings situated near essential services, acknowledging that a truly 'fully sustainable home' remains an elusive ideal. #SustainableHouses #ClimateResponse #PassiveSolar #EnergyEfficiency #EcologicalSustainableDevelopment #LifeCycleAssessment #BuildingCodes #NatHERS #BASIX #Passivhaus #PhotovoltaicPanels #CarbonNeutral #UrbanPlanning
