In conversation with Esther Van Eeden on Passive House design

This article discusses the growing trends of smart, sustainable, and health-conscious home design. It highlights the concept of 'passive houses,' a specific construction standard developed by Swedish and German scientists and engineers, emphasizing their energy efficiency and minimal heating requirements. These homes feature excellent insulation, airtight seals to prevent heat loss, triple-glazed windows, and orientation for optimal natural light and shading, with a Ventilation Heat Recovery system (VHR) for air circulation. While passive houses are not necessarily more expensive to build than other new homes meeting high BER ratings, high-end developments like Drumnigh Oaks showcase these principles with luxurious interiors. Interior designer Sara Cosgrove of Grove & Co. exemplifies this approach in her work at Drumnigh Oaks, integrating sustainable materials such as curtains made from recycled plastic bottles and sintered stone countertops, avoiding petroleum-based components. She stresses the importance of scrutinizing material ingredients to minimize chemical use, drawing a parallel to the hidden ingredients in processed food. The article also mentions the use of rugs with the 'Care & Fair' label, promoting ethical labor practices and environmental responsibility. Additionally, recycled paint from Enable Ireland's collaboration with the Rediscovery Centre is utilized, demonstrating that sustainable options can maintain high quality. A significant concern addressed is indoor air pollution from furniture, fabrics, and building materials, which the Environmental Protection Agency (EPA) notes can be two to five times higher inside homes than outdoors. Formaldehyde and volatile organic compounds (VOCs) are identified as harmful pollutants. A new solution, Prestige by Fleetwood, an air-purifying paint, is introduced as a way to mitigate these pollutants by removing airborne formaldehyde and meeting indoor air purification standards. Róisín Lafferty, an interior designer, collaborated on this paint line, valuing the product's quality and the company's commitment to sustainability. Tiffany Jones of Beach House Interiors further expands on 'Wellness: by Design,' raising awareness about chemical pollutants released from common household items through 'off-gassing.' She advises consumers to look for certifications like FSC (Forest Stewardship Council) for furniture and OEKO-TEX® for fabrics, indicating responsible production processes. The article concludes by listing relevant organizations and upcoming events like the Ideal Home Show, where these innovations will be presented, underscoring the shift towards healthier and more environmentally friendly living spaces. #HomeDesign #SustainableLiving #PassiveHouse #InteriorDesign #EcoFriendlyMaterials #IndoorAirQuality #GreenBuilding #HealthConsciousHomes

Passive house design is a standard for creating highly energy-efficient and comfortable homes, significantly reducing energy consumption and environmental impact. The concept, originating in the US and Canada in the 1970s, was later refined in Germany, leading to the establishment of the Passive House Institute (PHI) and its rigorous Passivhaus performance standard. The Passive House Institute US (PHIUS) further developed the PHIUS+ standard in 2015, which considers cost-effective and climate-specific performance criteria. These homes are designed to be extremely airtight and well-insulated, minimizing the need for traditional heating and cooling systems, often cutting energy bills by up to 90 percent. This is achieved through a holistic approach guided by key principles: thermal control, air control, radiation control, and moisture control. Thermal control focuses on maintaining comfortable indoor temperatures by utilizing continuous insulation throughout the building envelope, installing high-performance windows, and eliminating thermal bridges. Air control ensures superior indoor air quality through airtight sealing of the enclosure and balanced mechanical ventilation systems that incorporate heat recovery, minimizing outside air infiltration and optimizing conditioned air retention. Radiation control involves balancing solar heat gain, using daylighting when beneficial, and employing shading strategies, along with high-performance glazing like double or triple-paned windows, to prevent overheating and maximize energy efficiency. Moisture control is critical for preventing dampness and mold growth, achieved through optimal mechanical systems and careful attention to vapor control in the high-performance enclosure. Certification from the Passive House Institute (PHI) validates that a building meets stringent standards for thermal comfort, heating and cooling demand, humidity levels, airtightness (0.6 ACH50 or lower), and overall primary energy renewable usage. There are three levels of certification: Classic, Plus, and Premium, each representing increasing levels of energy efficiency and renewable energy generation. While often associated with new construction, passive house principles can also be applied to existing homes through the EnerPHit certification system for renovations and retrofits. This system uses similar principles but offers less rigorous metrics, allowing homeowners to upgrade their properties by insulating foundations, replacing windows, installing heat-recovery ventilation, incorporating renewable energy, and addressing drafts. The benefits of passive house design include a reduced environmental footprint due to lower energy consumption and carbon emissions, improved indoor air quality through better ventilation and reduced contaminants, and enhanced overall comfort due to consistent temperatures and reduced noise. Homeowners also experience significant cost savings on heating and cooling, and the durable design contributes to the home's resiliency. However, there are initial drawbacks, such as higher upfront construction costs, typically at least 10 percent more than conventional homes, though tax breaks can mitigate some expenses. The complexity of the technology and certification standards can be challenging for some homeowners to fully grasp, and local weather conditions might occasionally necessitate a backup heating system. Despite these challenges, passive house design represents a significant step towards sustainable and efficient living. #PassiveHouse #EnergyEfficiency #SustainableDesign #GreenBuilding #HomeComfort #IndoorAirQuality #ClimateChange #BuildingStandards

Architect Trey Farmer and designer Adrienne Farmer embarked on a comprehensive renovation of their 1914 craftsman-style home in Austin, Texas, aiming to transform it into a hyper energy-efficient residence meeting Passive House standards. The original home, despite its charm, lacked insulation, featured single-pane windows, and had no subfloors, making it energy inefficient and susceptible to noise from a nearby highway. Their objective was to create a home that was both functional and highly sustainable. To achieve this, Trey Farmer collaborated with his former boss, Hugh Jefferson Randolph, an Austin-based architect known for his extensive experience in renovating historic homes in the Clarksville District, an area rich in history as the oldest surviving freedmen’s town west of the Mississippi. Randolph's expertise was crucial in balancing the modernization efforts with the preservation of the home's historical character. The resulting project, named the Theresa Passive House, stands as a benchmark for energy efficiency in the Southern U.S., demonstrating that historical residences can be updated to meet contemporary sustainability requirements without sacrificing their original charm. The renovation expanded the 1,400-square-foot, single-story home to include three bedrooms, two-and-a-half bathrooms, and a flexible loft space currently used as an office and for storage. A significant addition is the back screened porch, designed to be contemporary and spacious, offering views of downtown Austin and connecting the interior with the landscape. The design emphasized the interconnectedness of sustainability, resiliency, and well-being, focusing on energy efficiency, thermal comfort, indoor air quality, and responsible material selection. The home's compact, rectangular volume was shaped by the existing lot and site setbacks. A key achievement of the Theresa Passive House is its remarkable energy performance, resulting in an average monthly energy bill of just $10 for the Farmers. This project is notable as only the third Passive House in Texas and the sole Phius-certified, source-zero project in the Southern United States, meaning it generates more energy than it consumes. The home is equipped with photovoltaic panels from SunPower and a Tesla Powerwall, allowing it to produce its own electricity and remain operational during power outages, functioning as its own energy hub. To seamlessly integrate the home into its 100-year-old neighborhood, the design emulated the aesthetic of the original large front porch. The interior layout, initially choppy, was reconfigured to include a new entry corridor with concealed storage, an open-plan kitchen, living, and dining area bathed in natural light. The kitchen, inspired by functional commercial kitchens, features an 11-foot engineered quartz island, a dramatic overhead light well, and a built-in tea bar. The primary suite utilizes natural, non-toxic materials, with Moroccan Tadelakt walls, Zellige tiles, and an oversized soaking tub contributing to a tranquil and serene atmosphere. Living in the Theresa Passive House has provided the Farmers with valuable insights into the performance of a passive home in a hot, humid climate. Trey Farmer expressed satisfaction with the home’s performance during extreme weather conditions, including Texas summers and cold snaps, while acknowledging the ongoing learning process of maximizing its utility.

Residential design presents significant opportunities for architects to create positive and resilient ecological impacts, benefiting both homeowners and the environment. While large-scale projects often receive sustainability accolades, single-family residential designs are a consistent project type in the U.S. and can collectively achieve substantial reductions in whole-life carbon emissions. This approach is particularly effective when addressing climate-appropriate design, insulation, and mechanical ventilation, especially in cold regions where heating costs are high. Integrating Passive House principles, for instance, can lead to financial savings for homeowners through reduced fuel costs and improved indoor comfort. The firm OPAL approaches sustainability through five dimensions: habitable planet, circular resources, protected water cycle, resilient ecosystems, and healthy communities. For a habitable planet, architects have significant leverage in reducing greenhouse gas emissions, as buildings contribute approximately 40% of global emissions. Beyond operational efficiency, considering embodied emissions through sustainably sourced, bio-based materials like wood, cellulose, and high-recycled content metals can radically increase resilience and durability while offering immediate value to homeowners. In terms of circular resources, the focus extends beyond reusing existing buildings to designing new constructions for adaptability and reuse throughout a building's lifespan. Residential buildings, particularly single-family homes, often experience occupants across multiple life stages, necessitating designs that accommodate aging-in-place or multi-generational living. Such flexible designs reduce waste from renovations and make the building stock inherently more circular, healthier, and inclusive. Protecting the water cycle involves reducing potable water use, particularly for irrigation, by selecting native, drought-resistant plants. Designers should also manage stormwater on-site to prevent erosion and pollution, using it to reduce the need for potable water and opting for gravity flow over pumping to decrease energy demand. Creating resilient ecosystems means minimizing the "human-only" areas on a site and designing spaces that promote biodiversity. This includes considering the ecological impact of materials and incorporating features like bird-safe glazing. Finally, fostering healthy communities centers on creating healthy indoor environments. A non-negotiable aspect is avoiding the combustion of fossil fuels for heating or cooking within buildings, as this is a major source of indoor air pollution. Instead, electric alternatives and 100% fresh air mechanical ventilation with energy recovery systems are recommended. These strategies, combined with access to daylight, natural views, and bio-based finishes, contribute to the physical and mental well-being of occupants. The article emphasizes that even small-scale residential projects can achieve significant sustainability outcomes by synthesizing and simplifying ecological design principles, aligning with frameworks like the AIA Framework for Design Excellence. #ResidentialDesign #Sustainability #GreenBuilding #PassiveHouse #CircularEconomy #WaterConservation #EcosystemResilience #HealthyHomes #SustainableArchitecture

Leeuw House, designed by Belgian studio NU Architectuuratelier for a young couple, is located on a vacant plot in Sint-Pieters-Leeuw, near Brussels. The design aims to blend traditional architectural forms with modern materials and energy efficiency. The house's exterior features fibre-cement tiles, chosen for their cost-effectiveness and natural, uncoated materiality, which provides a varied colour palette unlike the more uniform appearance of coated tiles. This material choice covers both the facade and the roof, creating a cohesive, latticed surface. The project prioritizes energy efficiency, adhering to Passive House standards, a collaboration with Ghent-based engineering firm Robuust. The construction employs an airtight structure, significantly reducing the need for additional heating or cooling. The architects noted that the underfloor heating system installed in the house has not yet been required, underscoring its impressive thermal performance. This focus on sustainability and low energy consumption is a core aspect of the design. Architectural orientation plays a crucial role in the house's energy strategy and internal environment. The north facade is largely solid to minimize heat loss, while the south and west facades are extensively glazed. This maximizes passive solar gain, allowing ample natural light and warmth to penetrate the interior, simultaneously directing views towards the adjacent fields and away from nearby structures. This thoughtful placement ensures privacy and enhances the connection to the natural surroundings. The house integrates multiple entry and exit points to create a dynamic relationship with its site. These include a street-level ramp leading to the side of the house, direct access to a rear terrace, and external stairs from the first floor to the surrounding landscape. Green doors and shutters are incorporated to introduce a vibrant splash of colour to the otherwise grey exterior, a choice made collaboratively with the clients to enliven the building's aesthetic. Internally, Leeuw House is structured across three storeys, including a basement garage and three bedrooms on the first floor. The main living areas, such as the dining room, kitchen, living room, and study, are arranged on half levels between the ground and first floors. This split-level design creates a continuous, spiral-like internal landscape. The layout avoids separate circulation areas, instead using metal stairs to connect open-plan spaces, fostering a sense of flow and visual connectivity. As one ascends, the spaces transition from more public to more private zones, each offering unique views and qualities. Material choices within the interior further contribute to the house's functionality and aesthetic. Concrete flooring is used throughout, chosen for its thermal mass properties, which allow it to absorb heat during the day and release it gradually as temperatures drop. Birch plywood is utilized for the kitchen and storage cabinetry, providing warmth and texture. The metal floor plate supporting the upper level is left exposed, doubling as the ceiling for the ground floor. This industrial aesthetic was a client request, ensuring that structural elements remain visible and contribute to the overall design character. Photography for the project was provided by Stijn Bollaert, capturing the essence of Leeuw House's unique design and material application. #ResidentialArchitecture #FibreCementTiles #PassiveHouse #SustainableDesign #ModernHome #BelgianArchitecture #NUArchitectuuratelier #EnergyEfficient

Steffen Welsch Architects were tasked with expanding a 1930s, 1,291-square-foot Californian bungalow in Melbourne to accommodate a growing family and frequent guests. The clients sought increased space alongside sustainability, flexible interiors, evolving privacy considerations, and future accessibility. The architectural solution involved adding a 1,259-square-foot rammed earth wing that sweeps off the back of the original house, curving along the property line to maximize solar gain and create a communal courtyard. The design divides the home into four distinct zones. The existing bungalow now serves as the children and guest area, comprising two bedrooms, a playroom, and bathrooms. Each zone in the expanded home features its own outdoor space. The architects strategically positioned the new addition to capture sunlight, forming a central courtyard that allows occupants to view their own home rather than a boundary fence, addressing the challenge of a south-facing extension on a compact inner-city block. Sustainability was a core principle, focusing on minimizing both embodied and operational energy. This was achieved through passive solar design, optimal building orientation, high-performance windows and doors, and the use of rammed earth. Rammed earth was chosen for its low embodied energy and its contribution to the building's thermal mass. An entry hall connects the original bungalow to the addition, leading to the new master suite. Built-in storage, clad in charred wood, was incorporated for flexible use and accessibility. The connecting corridor, featuring polished concrete screed floors, leads to shared living spaces, with high clerestory windows in the rammed earth walls providing ample natural light. A study is integrated into this corridor with external access, and an interior window from the kitchen overlooks the study and hall. The shared living spaces open onto the communal courtyard through a curved glass wall. The kitchen features flat-front cabinetry and round backsplash tiles with a pastel glaze. Material selection emphasized functionality and user interaction, with a focus on solar heat radiation, natural ventilation, and durable surfaces. The bathroom incorporates wood-paneled walls that echo the rammed earth striations, using wormy chestnut and recycled blackbutt for the counter. The playroom, located in the original house, also faces the new courtyard. The addition's design thoughtfully combines the lightweight timber-clad aesthetic of the original bungalow with the robust character of earth construction, creating a home that is both functional and aesthetically harmonized with its surroundings. #HomeDesign #RammedEarth #SustainableArchitecture #BungalowExtension #MelbourneArchitecture #FamilyHome #PassiveSolarDesign #FlexibleLiving #ArchitecturalRenovation

The COVID-19 pandemic significantly influenced multifamily residential building design, necessitating a rethinking of community spaces to ensure safety and comfort in high-density living. Nate Jenkins, an associate principal at OZ Architecture, outlines ten emerging trends that address these challenges, focusing on creating adaptable and healthy living environments. Historically, amenities in multifamily buildings were concentrated on upper floors to impress prospective tenants, often requiring elevator use. The new trend shifts towards integrating ground-floor and second-floor mezzanine amenities. These lower-level spaces enhance street-level engagement and offer more permeable physical connections through operable windows and doors, facilitating safer and more accessible interaction within the building. This move balances the continued presence of rooftop amenities with the practical benefits of street-level engagement. Crowded elevators are being addressed with the implementation of smart elevator systems, a technology more common in office buildings but now making its way into residential complexes. These intelligent systems optimize passenger flow, reduce wait times, and minimize large gatherings in lobbies by making fewer stops. Users can monitor car occupancy, allowing for more informed and safer travel decisions. Traditional open common spaces, designed for large group mingling, are being reconfigured into smaller, more defined gathering areas. Drawing inspiration from restaurant design, architects are partitioning open spaces into intimate "rooms" that can accommodate four to ten people. This can involve using elements like screen walls, planter-box partitions, canvas separators, or permanent landscape treatments, both indoors and outdoors, to create a sense of personal space while maintaining a communal atmosphere. Addressing air quality, new ventilation systems are being engineered to maximize fresh airflow. The emphasis is on increasing the operability of windows, skylights, and other elements to bring fresh air into all areas, from individual units to corridors and common spaces. Building systems are being upgraded to provide higher concentrations of fresh air, allowing buildings to "breathe" more effectively by facilitating the intake of fresh air and the exhaustion of stale air, benefiting all occupants. Stairwells, traditionally viewed as utilitarian and often poorly lit, are being transformed into significant amenities. Wider, daylit staircases with a residential aesthetic are becoming the "new circulator" within buildings. Designers are incorporating art, color, materials, and natural light sources like windows and skylights to activate these spaces, encouraging their use as a healthy alternative to elevators and enhancing the overall residential experience. Open-concept co-working spaces are evolving into private, reservable, or rentable conference rooms within residential buildings. As communal rooms faced reduced usage, reappropriating them into private workspaces offers residents a convenient and safe on-site working environment. This approach not only adds to the building's attractiveness but also presents a potential new revenue stream for landlords, as residents might prefer to rent an office within their building rather than at an external co-working facility. Large, glittering public pools, often seasonal and expensive to maintain, are being replaced by intimate lounge areas designed for small groups. The impracticality of pandemic-era restrictions on communal pools, combined with their significant space consumption, has led to a shift towards partitioned hangout spaces. These new designs aim to create more accessible outdoor areas for all residents, fostering smaller, more manageable social interactions. Indoor fitness centers are being redesigned to be less crowded, featuring large fresh-air ports such as roll-up garage doors and sliding glass doors. There's also an increased integration of outdoor space for training. The traditional model of closely packed exercise machines is being phased out in favor of open-air workout spaces that may include different flooring surfaces, like artificial turf, mimicking outdoor playing fields and promoting a healthier exercise environment. Finally, in individual residences, small or inoperable windows are being replaced by larger, sliding glass doors with Juliet balconies. This design allows residents to open up their units to the outdoors, effectively extending their living space and bringing fresh air and natural light into their homes. Juliet balconies, offering direct outdoor access without the full footprint of a traditional balcony, are becoming a standard feature in many new unit designs, reflecting a desire for greater connection to the exterior. #MultifamilyHousingDesign #PostPandemicArchitecture #CommunityBuilding #SmartHomeTechnology #SustainableDesign #UrbanPlanning #ResidentialAmenities #InteriorDesignTrends #WorkFromHomeSolutions

Architect Nadine Engelbrecht designed an off-grid modern home, named The Conservatory, for her parents on their 80-acre farmland outside Pretoria, South Africa. The parents requested a residence that did not resemble a conventional house, seeking an escape from urban life. Engelbrecht responded with a barn-inspired design spanning 6,458 square feet, featuring an unconventional floor plan that prioritizes integration with the natural surroundings and passive climate control. The Conservatory's most striking feature is its massive glass facade, which can retract upward at the push of a button, opening the lofty interiors to the surrounding grassland. This design draws inspiration from vernacular African barns. The home's construction utilizes durable, low-maintenance materials such as exposed steel, concrete soffits, and cement-washed bricks. The interior aesthetic combines warm timber tones with polished concrete floors and industrial-style cabinetry, creating a modern, streamlined look. Optimal orientation and architectural elements like a large overhanging patio and timber shutters are strategically incorporated to manage sun exposure and maintain comfortable indoor temperatures throughout the year. Designed for a couple, the main living areas and high-ceilinged volumes are contained within a single level. Central to the home is a conservatory, equipped with solid and translucent roof-sheeting and sufficient insulation to optimize passive climate control. In winter, the conservatory is configured to maximize solar gain and prevent cold air ingress, with passive heat released into adjacent living spaces when glass partitions are open. During warmer summer months, the automated glass facade of the conservatory opens up, transforming into an outdoor patio that facilitates natural breezes and circulation throughout the house. The home also features unique architectural details, such as a glass floor within the conservatory that offers a view into the wine cellar below, accessible via a seamlessly integrated trap door. Guest suites for visitors are located in a separate lower-ground area, featuring their own private entrance and outdoor space, ensuring privacy and independent access from the main residence. The master bedroom is situated on the western side, providing a balcony that is ideal for enjoying sunset views. A sunlit workspace and a versatile leisure room connected to a fully-glazed study further enhance the functionality and appeal of the home. The design is deeply influenced by the site's natural characteristics, with the dwelling partially submerged into the hill. Veld grasses extend onto a portion of the roof, and vegetation permeates the interior through the central conservatory, blurring the lines between built environment and natural landscape. Habitable spaces are strategically oriented around the conservatory to maximize views of the surroundings. The project credits include Nadine Engelbrecht for architecture, Hans Boursema Boukontrakteurs as the builder, DMV Structures Inc. for structural engineering, Nandi Koster for landscape design, and Marsel Roothman Photography for the visuals. #OffGridHome #ModernArchitecture #SouthAfricanDesign #PassiveClimateControl #BarnInspired #SustainableDesign #RuralLiving #ArchitecturalInnovation #TheConservatory

The article discusses various aspects of creating a sustainable home, drawing insights from Delaware experts in architecture and horticulture. It emphasizes the growing importance of sustainability in residential design and everyday living. Scott Sampson, a LEED-accredited registered architect and principal of Spring Studio Architecture, highlights key elements of sustainable home design. He focuses on maximizing natural light, utilizing super-insulated building envelopes, and incorporating passive solar techniques. Passive solar involves designing a home to absorb winter sunlight for heating and block summer sunlight to reduce cooling needs. Sampson also advocates for integrating plants indoors to improve air quality and minimize indoor air pollution. He notes that while sustainable choices can sometimes impact budgets, especially with rising inflation, there is a dedicated clientele committed to eco-friendliness. For home renovations, Sampson points out the challenges and opportunities. The primary focus for existing homes is improving insulation and air sealing to control air infiltration. This includes maximizing insulation and strategically managing window placements and overhangs to leverage solar angles for heating in winter and shading in summer. In new builds, orientation is a critical factor, with south-facing homes being ideal for maximizing solar gain. This approach allows a house to largely self-heat during cooler months by utilizing southern-facing glass, while architectural features like overhangs and sunscreens prevent overheating in warmer months. Sampson also discusses sustainable materials, defining them as those that do not release formaldehyde or volatile organic compounds (VOCs). He stresses the importance of using locally sourced materials, particularly wood from well-managed forests, and choosing durable options that do not require frequent replacement. The article then shifts to sustainable gardening practices, building on a previous discussion about native gardens. Marcia Stephenson, director of advancement for the Delaware Center for Horticulture (DCH), shares her experience with growing fruits and vegetables in her suburban backyard. She has successfully cultivated figs and Asian pears, donating excess produce to community centers. Stephenson observes a rising interest in kitchen gardens, particularly spurred by the pandemic. She highlights the educational benefits for children, who learn about food origins by planting seeds and watching them grow. Her fig tree thrives on the warm, sunny southern side of her home, benefiting from radiant heat, while her Asian pear tree benefits from cross-pollination. She also grows various vegetables like lettuce, tomatoes, carrots, beets, cucumbers, Asian turnips, radishes, herbs, and bok choy. Raised beds are recommended for easier weeding and protection from pests like bunnies. Nora Melley, who manages education programs at DCH, discusses options for small spaces, such as dwarf fig trees and cascading blueberries suitable for containers and hanging baskets. She mentions challenges like birds eating blueberries and advises home gardeners to amend soil with sulfur for optimal blueberry growth, as Delaware's average soil pH is 6.5, while blueberries prefer a pH of 4.5. Patience is emphasized for fruit-bearing trees and shrubs, with soil amendment taking months and significant harvests from trees taking several years. Melley encourages starting small, suggesting simple methods like regrowing scallions from root ends in a window box, to avoid feeling overwhelmed and gradually expand sustainable gardening efforts. #SustainableHome #EcoFriendlyDesign #GreenArchitecture #SustainableGardening #PassiveSolar #VolatileOrganicCompounds #NativePlants #HomeRenovation #Delaware
