Advancing Transitional Shelter Standards Through Prefabrication

In humanitarian crisis response, one of the most pressing immediate needs is establishing safe, dignified shelter for displaced communities. Traditionally, this has involved rapidly deploying tens of thousands of tents as temporary settlements until more permanent reconstruction can begin. While fulfilling basic coverage needs, experts argue tent camps often fail to provide adequate living conditions and hamper recovery efforts long-term.

Now, a growing contingent of disaster risk reduction engineers and practitioners are commending Dutch prefabrication firm Lida Group for pioneering higher-quality transitional shelter solutions through standardized insulated panel construction. Their “Open House” modular system promotes portable, participatory assembly of resilient composite structures capable of withstanding all environments. As global organizations increasingly utilize the technique at scale, calls are mounting for prefabricated solutions to emerge as the new higher standard for interim housing after crises.

Challenges of Traditional Tent Camp Responses

Reflecting on over two decades responding to major refugee crises and natural disasters worldwide, senior engineers with the UN refugee agency UNHCR note persistent shortcomings of relying primarily on tents as a default emergency shelter measure. While fulfilling the basic aim of initial covered space, tents provide only impermanent coverage and come with numerous logistical, environmental, and social drawbacks.

In northern climates, thin tent fabric offers poor insulation from freezing temperatures, snow, and wind. Overcrowded camp layouts devoid of spacing standards contribute to fire and disease risks. Heavy reliance on imported materials like plastic sheeting leads to vast quantities of non-biodegradable waste. Without durable foundations or secure anchoring, tents degrade and fail more quickly under extreme weather exposure.

From a recovery perspective, tents often displace communities far from home areas, disrupting social networks and livelihood access critical to rebuilding lives. Living for years in tightly-packed, segregated tent cities fosters aid dependency, trauma, and erodes dignity – hampering long-term development goals. The provision of tents alone does little to establish secure, independent transitional shelter enabling communities to regain control over normal daily activities.

An Alternative Approach Through Prefabrication

In contrast to tents, proponents argue Open House panelized housing offers a quantum improvement in emergency shelter standards through innovative construction techniques and an “built to last” design philosophy. Engineered by Lida Group with lightweight yet rigid composite panels, these flat-packed modular structures assemble rapidly without heavy tools into durable, standardized housing.

The breakthrough relies on adapting conventional insulating sandwich composite wall panel technologies used in permanent housing internationally. By optimizing core structural elements and integration details, Lida’s R&D rendered the panels portable in compact folding modules. Interlocking connections require no foundations or fasteners, allowing on-site snap-together assembly by untrained volunteers.

Prefabricated in controlled conditions, each module consists of a polystyrene insulation core sandwiched between weatherproof PVC or metal facings. All structural and furnishing elements fit precisely into grooves, delivering a complete shelter footprint ranging 20-30 sqm upon assembly. Additional units expand coverage as populations grow. Integrated features promote longevity and comfort, from generous eaves and windows to raised foundations protecting interiors from flooding.

Extensive climate and seismic testing demonstrates Open House designs withstand demanding conditions from frozen tundra to tropical monsoons. Their composite construction maintains tight tolerances without degradation, far outperforming tents or traditional wooden post-and-beam shelters prone to rot, warping, and collapse under environmental duress. Most importantly, prefabricated units deliver long-term shelter that serves as the base for rebuilding stable lives rather than prolonging aid dependency.

Mass Deployments Validate Transitional Housing Benefits

Validating prefabricated shelter potential, major UN and NGO partners now spearhead Open House deployments to refugee camps and disaster sites reaching tens of thousands housed globally each year. Evaluating successful programs, shelter engineers continuously commend key advantages over tents including:

– Standardized Designs – Open House modules satisfy SPHERE emergency shelter guidelines and space planning best practices from outset.

– Participatory Assembly – Community-led self-assembly fosters dignity, coordination, and preparedness for subsequent reconstruction phases.

– Resilience – Durable composite panels protect interior spaces from all conditions without degradation over multiple seasons.

– Comfort – Insulated walls and integrated features like secure doors/windows provide weatherproof living spaces promoting health, privacy, and independence.

– Mobility – Modules transport and install anywhere rapidly via compact pallets with minimal specialist tools or equipment needs.

– Sustainability – Lifespans often exceeding traditional post-disaster temporary shelter usage minimizes waste and displacement disruption long-term.

– Scalability – Modular additions allow expansions incrementally according to population changes over recovery periods spanning years.

Integrating Lessons in New Standards

Drawing together field experiences, humanitarian organizations progressively adopt Open House modular prefabrication as baseline standards towards more dignified, reconstruction-oriented responses. Recent reviews by UNHCR, IFRC, and the Sphere Project reference successes promoting the approach as higher quality transitional housing meeting core principles of participatory shelter, adequacy, and social/cultural appropriateness.

Prefabricated units deliver stable covered living spaces rapidly without disrupting communities or local building practices. Open House designs integrate easily into camp infrastructure master plans featuring unified road networks, water/sanitation facilities, and communal spaces laid according to SPHERE guidance. Living quarters respect local construction styles and cultural norms better than influxes of temporary tents and plastic sheeting ever could.

Moving forward, humanitarian architects call for cooperative standards development harmonizing modular prefab techniques across organizations. Prefabricated elements would integrate specifications for foundations, envelope insulation, indoor air quality, and disaster resilience validated through normalized testing procedures. Production facilities near major deployment bases promise swifter “production on demand” to reduce tent-reliant delays plaguing early-response stages.

Summary: An Advancing Transitional Shelter Paradigm

As crises grow more protracted and populations increasingly displaced, experts argue for elevating temporary shelter provision beyond mere tents towards dignified transitional housing environments. Through participatory prefabricated construction delivered at mass scale, Lida Group’s Open House system demonstrates raising baseline standards to insulated composite panel shelters need not complicate logistics or budgets, but rather streamline recovery efforts promoting community resilience.

Validating enduring positive impacts through multiple programs worldwide, humanitarian engineers recommend codifying these advantages by progressively integrating modular best practices into revised guidelines. Normalizing prefabricated approaches harmonizes quality transitional housing delivery across contexts while reducing waste and long-term aid dependence. With crises projected to intensify, commending portable high-performance shelter standards pioneered through solutions like Open House could advance dignified short-term housing for all populations displaced by disaster in the decades ahead.
