Calico Energy於2021年5月3日發布，約為395 GtCO2。根據IPCC和CONSTRAIN項目2019年底的估計，395億噸二氧化碳是我們剩餘的碳預算總額，有50%的機會將變暖限製在1.5°C。氣溫上升超過2°C所帶來的風險令人擔憂，而我們在減少消耗方麵做得還不夠。以建築為例:隨著圍繞能源效率和改造的巨大市場，你不會瘋狂地認為我們正在減少它們對氣候的影響。但2019年，建築的直接和間接排放量上升至10億噸二氧化碳。這是有史以來最高的，幾乎占我們整個預算的2.5%。我們的許多建築仍然非常低效。這個問題，以及任何可行的解決方案，都歸結於規模。考慮一下你的水電費賬單。偶爾，您可能會看到一個數據比較圖表——您的能源消耗如何與類似客戶的數據進行比較。 Say you're a mixed-use building owner (hey, maybe you are!) with commercial and residential tenants. That handy comparison chart? If your building is sub-metered, you don't have one. And you probably can't get it, even if you try. Now zoom out. Without baselines across all building types, there's no way to target efficiency work, meaningfully decarbonize the sector or leverage buildings as resources . Recent events in Texas highlight the pressing need for a better understanding and utilization of our buildings. The data we'll need, the only baseline data set that can truly scale our climate solutions for buildings, is inaccessible. But it doesn’t have to be. Data access that benefits everyone Imagine this scenario: building owners get accurate historical whole building data from utilities (monthly, daily, or hourly), utilities identify least efficient buildings and create pipelines for existing programs, and program administrators, vendors and regulators can use the data to benchmark, evaluate opportunities, calibrate and perform M&V. It's a win-win-win, and it's possible. That's not to say it's easy. If you work within a utility or alongside one, you know that the systems that govern data are some combination of complicated and/or outdated. Considering those who need the data might not be utility account holders and that buildings don't always align with typical utility customer segmentation for programs, it's clear that traditional operating mentalities won't deliver the data we need. To make the scenario above possible, one very important thing needs to happen first: Utility-enabled whole building data access. So, how do we make it happen? Take a customer-type agnostic approach. When utilities move to a customer-agnostic approach, it doesn't mean that their customers become unimportant. Instead, it means that they're looking at data for buildings rather than customers; multitenant buildings are frequently many customers and of varied types. This approach makes it easier on building representatives (from owners to energy efficiency consultants) and gives utilities the ability to target buildings for EE upgrades and incentives. Combine utility data and building owner knowledge. Multi-tenancy is the thorn in the side of utility-enabled data access: Building owners have no rights to tenant data, and utilities only have customer and meter data (without that building-level view). Luckily for utilities, building owners know their units and who their tenants are/were – better than a utility ever could. An approach that leverages utility data and building owner knowledge is an elegant way to get accurate, aggregated data in building owner hands while maintaining privacy. Get involved with the stakeholder community. Whether you're a utility program manager facing an ordinance that will require new data access or a legislator or city official trying to reduce energy consumption in buildings, there are groups eager to work on the problems and solutions with you. Organizations like MEEA , ACEEE , and the Institute for Market Transformation are committed to providing best practices and helping regions shape effective building-focused legislation. Conversations about the future of the building sector are happening as we speak, and we need more utilities, technologists, and energy experts at the table. For the foreseeable future, approaches to building decarbonization and sustainability will vary region-to-region and utility-to-utility. Meaningful change, the kind that will reduce building sector emissions, depends on scalable solutions, and that requires generating and leveraging utility data at the building level. Fortunately, the model to make this possible exists – and it's a win-win-win for all involved.
