Early housing had no technology, while 20th century housing saw evolving technology and 21st century housing has organized technology. The document defines passive house standards for ultra-low energy buildings requiring little heating/cooling energy. Key benchmarks are space heating/cooling energy under 15 kWh/m2 per year, total primary energy under 120 kWh/m2 per year, and an air tightness of 0.6 air changes per hour. The passive house principles are an air tight building envelope, high efficiency windows and doors, super insulation, controlled ventilation with heat recovery, and thermal bridge free construction. The example passive house built met an air tightness of 0.37 air changes per hour, with a final HERS score

Passivhaus Designing for heating load 25th Passivhaus ConferenceNick Grant
Passive solar is dead, long live super-insulation. This paper was presented at the 25th International Passivhaus Conference, online. Passivhaus (Passive House) is the leading international standard for comfortable low energy buildings. This paper recommends designers consider designing for the alternative metric of peak heating load rather than annual energy demand. This means optimising glazing for daylight and views and not for solar gain.
Monitored energy use of air to water heat pumps in single Passivhaus dwellings is compared with the design estimates using PHPP. Heat pumps using conventional HFC refrigerants are compared with CO2 refrigerant. The latter gave improved performance for hot water heating but significantly worse for space heating. This is due to the very low heat load of Passivhaus dwellings being below the normal output range of available heat pumps.
Is Passivhaus a step too far? South Pacific Passive House Conference Auckland...Nick Grant
Is the Passivhaus standard too extreme for a mild climate such as New Zealand? Do we really need to do all the modelling and calculations if we max out the insulation and air tightness? Nick Grant's first presentation at the first South Pacific Passive House Conference in Auckland aims to explore these questions.
griha norms that are necessary to be followed when going for a rating system for an existing building has been explained here. In addition to that, two case studies have also been consideration.

April Forum: The Hit List - The Top Tips to Green NYC Buildings Part 1 of 3 E...GreenHomeNYC
Are you a homeowner, commercial property owner or property manager concerned with increasing energy costs?
Are you a contractor, architect, interior designer or real estate broker whose clients have asked about green buildings?
Do you plan to renovate, buy or develop a building?
Come hear The Top 10 Tips to make NYC Buildings Greener! Learn ways you could improve your building investments, prevent the loss of energy and money, and be environmentally conscious by constructing, renovating and maintaining green buildings!
Our panel discusses their top 10 tips to:
» reduce energy and water use;
» improve occupant health, safety and comfort with non-toxic, reusable and recycled building materials;
» prevent waste and pollution.
Local boy, Robert Steininger explains how he turned his 1970’s three bedroom semi into an energy high performer. His heating and hot water bill for the full year is €450. He explains what he had done, how it worked out, what went well and what he would do differently if he was doing it all again.
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.

Join us as Finegold Alexander presents the study for the Lowell Trial Court, a 250,000 SF state courthouse designated by Gov. Patrick’s Zero Net Energy Building Task Force as one of three public demonstration projects addressing the challenge of designing public buildings to high sustainability standards.
The engineering components of the study involved proposals for energy reduction and on-site production, investigated through a multitude of computer models and cost-to-benefits charts and analysis. Architecture and architects must change. Architectural form is a critical element in achieving any sustainable goals, including zero net energy. This session will look at the Lowell Trial Court design process and the iterative schemes the team produced. We will discuss building massing, orientation, urban context and all the elements we always address in every project. Now we find our attitudes toward these traditional design criteria are influenced by the integration of sustainable design. Design for zero net energy caused this team to think and collaborate differently with consultants, client and user groups.
A zero-energy building, also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), or net zero building, is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site,or in other definitions by renewable energy sources elsewhere.These buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount.

The heating system of the future, without traditional heating system. Can a house be constructed without a conventional heating system and still achieve a good comfort level in summer as well as in winter? Yes it can. Nothing magical: the right design, the right materials, and a ventilation system with heat exchanger can be enough. The following minute lecture by way of introduction to this innovative construction standard.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

A Brief History
3. What is Passive House
The term passive house refers to a rigorous, voluntary standard for
energy efficiency in a building
Resulting in ultra-low energy buildings that require little energy
for space heating or cooling
Thusly reducing its ecological footprint
4. Benchmarks in a Nutshell
Space Heating/Cooling Energy Demand
15 kilowatt hours per square meter of Treated Floor Area per year or 10 Watts per
square meter peak demand or in Imperial units 4.75 kBTU/sf*yr and 3.2 BTU/hr*sf
respectively.
Primary Energy Demand
Total energy to be used in the building operations (heating + cooling + lighting +
equipment + hot water + plug loads, etc…) is limited to 120 kilowatt hours per square
meter of Treated Floor Area per year or in Imperial units 38.0 BTU/sf*yr.)
Airtight Enclosure
Allowable limit of 0.6 air changes per hour at 50 Pascals pressure (ACH50) that is
verified with an onsite blower door test (pressurized and depressurized)
