Green Information: SIP Building System

A Build It Green home is environmentally friendly for several reasons

Timber products, sourced from well managed forests, ensure that more trees are planted than are cut down for processing. The younger trees that are planted as replacements are better adapted for reducing atmospheric CO₂ thus further reducing greenhouse gases. In some instances, areas of deciduous trees are planted within conifer forests to encourage a diversity of wildlife.

Build It Green Structural Insulated Panels are made from timber which is sourced from managed plantations and has a chain of custody accreditations for FSC and PEFC certified timber.

Timber is seen as a green building material because trees produce oxygen and remove carbon dioxide from our atmosphere and timber is the only truly renewable building material.

The polyurethane (PUR) core of insulation in the Build It Green Structural Insulated Panels is CFC/HCFC-free with zero Ozone Depletion Potential and has a Low Global Warming Potential (GWP).

Minimum Space Heating

The SIP Building System can reduce space heating demands by achieving U-values of 0.14 W/m²K or lower as standard and air permeabilities as low as 1 m³/hour/m² at 50 Pa.

This means that less non-renewable fossil fuels are consumed when heating the space available.

Minimal Landfill

The Build It Green SIP Building System is factory manufactured meaning there is minimal site wastage and therefore more efficient use of materials on-site. The minimal levels of site wastage means less site waste to landfill which also helps to reduce cost.

Code for Sustainable Homes

A Build It Green SIP Building System can help towards achieving a high score within the Code for Sustainable Homes.

The Code is the national standard for the sustainable design and construction of new homes, it aims to reduce our carbon emissions and create homes that are more sustainable.

PassivHaus

The term PassivHaus refers to a specific construction standard for buildings which have excellent comfort conditions in both winter and summer.

PassivHaus dwellings:

• are the worlds leading standard in energy efficient construction
• use efficient components and a whole house Mechanical Ventilation with Heat Recovery to achieve exceptionally low running costs
• are comfortable, healthy and sustainable

Basic Principles

A dwelling which achieves the PassivHaus standard typically includes:

• very good levels of insulation with minimal thermal bridges
• well thought out utilisation of solar and internal gains
• excellent level of airtightness
• good indoor air quality, provided by a whole house Mechanical Ventilation with Heat Recovery
• High Performance Windows & Doors

Build It Green offer a number of high performance building technologies that will assist you in meeting the PassivHaus standards. These include:

• Build It Green – SIP Building System
• Internorm high performance Windows & Doors
• Mechanical Ventilation with Heat Recovery
