Installing energy efficient windows like Intus windows in multifamily buildings can significantly reduce their energy consumption and carbon footprint. Analysis of older multifamily structures from the 1980s found that space heating accounted for 41% of their energy use. Intus windows, with a U-value of 0.15-0.17, can reduce space heating to just 6.5% of total energy use compared to older windows with U-values of 0.75 or higher. For example, a case study of a New York apartment building found that using more efficient standards like Intus windows could reduce each unit's energy use and carbon dioxide emissions by over 30%. This demonstrates that energy efficient windows can meaningfully cut the environmental impact of multifamily

Zehnder America a Fresh Look at Indoor Air QualityZehnder America
Home should be a place where you can breathe easy, but today that might not be the case. Indoor air pollution can be worse than outdoor pollution, and people spend about 87% of their time indoors, an average of 69% at home.
Environmental Protection Agency studies found pollution indoors could be two to five times higher than outdoor levels, and in rare cases up to 100 times worse. In this special report sponsored by Zehnder America Inc., we’ll outline causes of indoor air pollution and discuss solutions available to create a safe and comfortable
indoor environment.
Construction has changed a lot over the years, with new laws and regulations helping to promote better energy efficiency throughout the industry. Daniel Lambraia outlines some of the practices helping to make these standards the norm.

Josh Trent, Director of Communities & Design at Frontier Housing will discuss his success at reducing the construction
cycle time by more than 50%, and Frontier Housing’s award winning success at constructing homes to exceed the
Energy Star Standard.

Mechanical ventilation such as an energy recovery ventilator (ERV) or a heat recovery ventilator (HRV) provides a solution to a number of issues presented by natural ventilation. Proper ventilation is a critical consideration for homes and buildings. Poor ventilation can cause a buildup in indoor air pollutants like dust, pollen, mold, and household chemicals and lead to a lower living standard and poorer health of the building’s occupants.

The Fifth Assessment Report from the
Intergovernmental Panel on Climate Change is the
most comprehensive and relevant analysis of our
changing climate. It provides the scientific fact base
that will be used around the world to formulate
climate policies in the coming years.
This document is one of a series synthesizing the most pertinent findings
of AR5 for specific economic and business sectors. It was born of the belief
that the agriculture sector could make more use of AR5, which is long and
highly technical, if it were distilled into an accurate, accessible, timely,
relevant and readable summary.
Although the information presented here is a ‘translation’ of the key

Passive House in Crete
Passive House structures seamlessly merge comfort with minimal energy usage. Unrivalled design, skilled craftsmanship, top-tier windows, advanced insulation, and heat recovery ventilation distinguish Passive House construction.
Despite their high efficiency, these buildings harmonize inconspicuously with their traditional surroundings. Notably, a Passive House denotes a performance standard rather than a fixed construction approach. Designers have flexibility in achieving mandated energy targets, allowing creative freedom in construction methods.

1. Installing Energy Efficient Windows in Multifamily Buildings Cuts
Energy Consumption and Reduces Carbon Footprints
Most people livingin the UnitedStatesandeveryenvironmentalist knowswhata‘carbon

powerplants. Multifamilybuildingsmake upabout18% of our nation’shousingandthatnumberhas
beenincreasinginrecentyearsdue touncertaintyinthe real estate industry.Accordingtoananalysis
done byEnergy ProgramsConsortium85% of multifamilystructureswerebuiltbefore 1990 with
inefficientheating,cooling,plumbing,andlightingsystems.Thisunfortunate statisticisonlymade worse
by the fact that the majorityof familieslivinginmultifamilybuildingsare renterswithanannual income
of $31,000, and these lowerincome familiesthatneedenergysavings are forcedtopaymore forenergy
due to inefficacy. Thislowerstheirdiscretionaryincome andmakesthemmuch more vulnerableto

2009, rentersinmultifamilyunitsfacedanaverage rentincrease of 7.6 percent,while energycostsfor
these rentersrose by22.7 percent.
What can be done?
For multifamilybuildingsalreadybuiltandoccupied,itwouldbe unrealistic togo and replace all
the windowswithenergyefficientones.Atthispointinstallingthermostatstocontrol temperatures
duringtimesof lowenergyuse andusinglow-costtechniquesare the beststrategies forthese
apartments.Nevertheless,manynewmultifamilyhomesare
beingbuilttomeetthe demandfromcost conscious consumers.
For example,IntusWindowswereusedina48-unitmultifamily
projectinMaine that recentlywascompletedand now offers

windowscansignificantlycutenergyconsumptionand
therefore reduce carbonemissions.Inthe past,structural,
